Nuclear Power is Dangerous - Use with Care

For Calliban re #125

Just re-read #125, and appreciate the observations in general, and the closing line in particular. It reminds me of home design in a region with squirrels. If a home is not equipped with provisions to prevent access by squirrels, squirrels will find every possible point of entry. It has taken me a number of years to apply aluminum sheet to all the entry points the builders left behind, but the squirrels and I are getting along famously now.

I hope the Japanese are recovered from the errors in their earlier planning, and that future systems will be much more robust.

I am here today to post an observation that arises from your correspondence in another topic. I had pressed the question of what it would take to design a complete plant to make methanol and DME (two methanol molecules combined (more dense)), and you (no doubt wisely) came back with a paper from (about) 2021 that appears to offer a summary of the state of affairs. I'm looking forward to study of the paper, because it looks well done and the subject is important.

So! Here is my observation ... A plant based upon the already approved 50 MW SMR design would / could sit literally anywhere. It only needs atmosphere and a supply of water, and the water could be fetched by pipeline, since the output of the plant is going to be modest.

Whatever the cost of the plant may be, it will operate for many years. If the plant is well designed, it can substitute a fusion plant for the SMR when fusion becomes available, and the output of methanol an DME will continue without a hitch for hundreds of years.

Whatever the cost of the plant may be for the first installation, the cost of the plants will decrease over time, and everyone involved gets better and better at their respective specializations.

I am thinking about Senator Joe Manchin and his current devotion to and dependence upon coal fields in his state. If Senator Manchin could see a future for his constituents, running and maintaining plants of this type, then he might be willing to support legislation that requires all (or most) fuel produced for military purposes to be produced in house, using these plants.

In response to observations by Calliban in another topic, I asked Google for information about who might have appointed Milton Shaw to the Atomic Energy Commission ... I never did find that specific detail, but Google did find a lot of related snippets...

This is output from a Google search for “who appointed milton shaw to AEC”

From multiple snippets, from a book, and from an article, I am coming away with the impression that Milton Shaw single handedly did more damage to the American (US) nuclear program than anyone else, before or since.

This is a follow up to the question of Milton Shaw's tenure at the Atomic Energy Commission in the US.

20230405 ChatGPT Milton Shaw lookup

Hello again! I have an easy one for you today .... a simple lookup
Hello! Sure, what can I help you look up today?

Milton Shaw was appointed to the Atomic Energy commission ca 1964. can you find out who appointed this gent to the commission? He was a protege of Admiral Rickover. Was congressional approval required?
Milton Shaw was appointed to the Atomic Energy Commission (AEC) by President Lyndon B. Johnson in 1964. As a commissioner, he served from 1964 to 1971.
The appointment of AEC commissioners requires confirmation by the US Senate. Milton Shaw's appointment was confirmed by the Senate in July 1964.
It is worth noting that Admiral Hyman Rickover, who was a proponent of nuclear power and nuclear submarines, played a significant role in shaping US nuclear policy and had considerable influence over the AEC. It is possible that his relationship with Shaw may have played a role in his appointment.

Can you confirm that the senate had a Democrat majority in 1964?
Yes, that is correct. In 1964, the Senate had a Democratic majority. The 88th United States Congress was in session from January 1963 to January 1965, during which time the Democrats held a majority in both the Senate and the House of Representatives.

So it would be correct to surmise that the President, the Senate and the House all trusted Admiral Rickover to recommend Milton Shaw to the AEC?
It is possible that President Johnson, the Senate, and the House of Representatives relied on Admiral Rickover's recommendation in appointing Milton Shaw to the AEC. Admiral Rickover was a highly respected and influential figure in the field of nuclear power, and his recommendations would have carried significant weight in nuclear-related appointments.
However, it is also important to note that other factors, such as Shaw's qualifications and experience, would have been taken into account in his appointment. The AEC was responsible for overseeing the development and regulation of nuclear power in the United States, and it was essential that its commissioners had the necessary expertise and knowledge to fulfill their roles effectively.

Since Milton Shaw stepped down as a member of the AEC, at the request of Richard Nixon, a great deal of negative feedback has appeared in the press and online. It appears that Milton Shaw may have done great damage to the US nuclear program. Can you find anything one way or the other on this question?
Milton Shaw's tenure on the Atomic Energy Commission was controversial, and there were criticisms of his management style and decisions during his time in office. Some of the criticisms centered around Shaw's handling of the development of the fast breeder reactor, which was a key component of the US nuclear program. Critics argued that Shaw's decisions and management style delayed the development of the breeder reactor and ultimately led to its failure.
In 1970, President Richard Nixon requested that Shaw step down from his position on the AEC. While the reasons for Nixon's request are not entirely clear, it is widely believed that Shaw's management of the breeder reactor program played a role in his departure.
It is worth noting, however, that opinions on Shaw's legacy within the nuclear industry are divided. Some have argued that Shaw's caution in the development of the breeder reactor was justified and may have prevented a potential nuclear disaster. Others have criticized his approach as overly cautious and bureaucratic, and have argued that it ultimately hindered the development of nuclear power in the United States.
Overall, while there are criticisms of Shaw's tenure on the AEC, his legacy remains a matter of debate and interpretation.

Thank you! It is always an enjoyable experience (for me for sure) to work with you. Catch you next time.
You're welcome! I'm glad I could help, and I always enjoy assisting you with your questions. Don't hesitate to reach out if you have any more questions in the future. Have a great day!

MB4M, A cultural problem in Japan, I think. They seem to have a regimented culture, in which subordinates never ask difficult questions of authority. The Soviet Union had a problem that was in some ways similar. Still, I don't think the nuclear power sector in Japan is as bad as anti-nukes like to make out. The older power reactors at Fukushima, were not designed to cope with foreseeable initiating events at the site. The tsunami hazard is not something that most other countries have to contend with. This is the problem with taking a plant design from somewhere else and just assuming it will work for you without any external hazards analysis. If the plant had been built in most other places, it would have been OK. But Japan is one of the most seismically difficult places to build anything. They didn't adapt the plant design to local conditions. And Japan is particularly unforgiving environment. It is right on the Pacific Ring of Fire. It has volcanos, megaquakes, tsunami and typhoons. If there is a design weakness in anything built in Japan, Mother Nature will find it.

This is another take on SMR and Idaho National Laboratory

Could Compact Nuclear Reactors Be the Future of Electricity?

Nuclear power is clean, efficient, and safe, yet it’s vastly underutilized as a method of generating electricity. Sure, people have their fears about Chernobyl or Fukushima, but those don’t align with the data — statistically, you’re more likely to die in a wind turbine accident. So why don’t we use more nuclear energy?
The reasons, for the most part, boil down to cost. Building generators is expensive, fuel is expensive, training a workforce is expensive. But researchers at the Idaho National Laboratory think they have a solution to all three: Make reactors smaller.
Vox has a great piece about the INL and its efforts to build compact, inexpensive nuclear reactors. Researchers hope that by making new reactors smaller, they can be deployed more easily, massively lowering the barrier to entry for clean power.
Reducing the footprint of a nuclear installation from acres to square feet is a monumental task, but INL researchers think they’ve found the solution: Heat. As nuclear reactors get hotter, they produce energy more efficiently, allowing for more power to come from a smaller footprint.
Of course, extra heat means extra cooling, something traditional liquid-based systems just can’t handle. To solve this, INL researchers turned to new coolants — think less about antifreeze, more about molten metal or salt. With stable cooling at these higher temperatures, compact reactors can even use cheaper fuels, making nuclear even more practical for use in grids.
Vox’s full explainer is worth a read, and the story of the INL’s nuclear research is worth following. If their tests pan out, you might just start reading Jalopnik by the power of a compact, local nuclear power grid.

For SpaceNut re #131

Thank you for the link you provided to the overview of General Electric's web site about their long history of providing reliable steam turbines for many applications. I thought the 50% market share for nuclear sites is impressive!

If you have time, please investigate to see who is providing turbines for the non-steam materials that (I understand) may be flowing in newer reactor designs. On Mars I would expect CO2 might be considered as a fluid for energy transfer from thermal to mechanical form, but there may be other fluids under consideration.

A book on nuclear power arrived today, along with one about the Agile Project Management system.

I skimmed the book and confirmed that the author takes the danger of nuclear power seriously, so this topic is a good fit.

The author is Colin Tucker, and the title is How to Drive a Nuclear Reactor.

There are 264 pages including an index. I turned to Chernobyl immediately, and found that the author's account of events there is similar to Calliban's version, but there are minor differences. Notably missing, for example, is the characterization of the supervisor who directed the activity at the plant. Calliban's version is definitely more spicy.

The book was published in 2019, and small modular reactors were on the horizon at the time, but the author was doubtful of their future. Apparently he has decades of experience in Great Britain, running or at least participating in operation of a light water reactor.

The image of the Fermi pile under the Chicago Stadium stands is one I have not seen before, which I appreciated.

New nuclear reactor enters commercial operation, first in US in 30 years
Story by Breanne Deppisch • 1h ago
Georgia Power announced Monday that its Plant Vogtle 3 nuclear reactor has entered commercial operation, becoming the first new U.S. nuclear reactor to come online in more than 30 years.
Operators said the Vogtle 3 reactor has completed testing and is reliably supplying power to the grid.
The reactor will both provide an estimated 1,000 megawatts of power to the state, enough to power 500,000 homes and businesses, developers said. Once the new units are online, the four-reactor nuclear power plant will be the largest generator of clean energy in the nation.
“Today is a historic day for the State of Georgia, Southern Company, and the entire energy sector, as we continue transforming the way we power the lives of millions of Americans,” Southern Company President Chris Womack said in a statement.
Reactors for Unit 3 and 4 sit at Georgia Power's Plant Vogtle nuclear power plant on Jan. 20, 2023, in Waynesboro, Georgia, with the cooling towers of older Units 1 and 2 billowing steam in the background.

“With Unit 3 completed, and Unit 4 in the final stages of construction and testing, this project shows just how new nuclear can and will play a critical role in achieving a clean energy future for the United States,” he added.

The Plant Vogtle nuclear project was long stalled and is years behind schedule and billions over budget. Construction on Unit 3 began in 2013, and the project as a whole is $17 billion over budget.
On Friday, Georgia Power said it has been cleared by the Nuclear Regulatory Commission to begin loading radioactive fuel into its other new reactor, Unit 4, which it plans to do beginning in September.
Unit 4 is expected to be placed in service during the late fourth quarter of 2023 or the first quarter of 2024.

Calliban,

I've already watched that video. My takeaways were, stop trying to save a little bit of money on concrete and steel, make sure that all components are ready for fabrication or installation before construction crews show up, make sure you actually know how to build something to the standards required, and that we should have a NRC inspector onsite with the construction crew, telling them exactly how they must build something to comply with nuclear construction regulations, and then you don't need to worry about re-work or re-certification to a set of plans that were not originally submitted to the NRC for approval. Beyond that, all the nuclear components should be test-fitted together ahead of time so that you are 100% sure that all holes line up for anything that must be bolted together.

if Russia blasted Plutonium across the Moon in a Failed Landing did it 'Break The Law'?

When people dump stuff on the Moon who will clean up the Waste and Lunar-Mess of Toxic Garbage left behind?

Yes the Moon is already dangerous, the dust is possibly toxic and it has no atmosphere so it is radioactive

However Luna-25 seems to have been carrying Pu-238 , its not a lot but perhaps a significant size and if an Astronuat or Colonist in a future mission was on the Moon walking around there is now a chance somebody could pick up some of it on their shoe and bring it back into their space habitat. The Pu or RTG would now be spread over a large area of the landscape. Legally does the Moon Treaty or Lunar Agreement or Outer Space Treaty did it try to say anything about mankind dumping waste and creating outerspace exclusion zones?

QUOTE
The General Assembly

Recognizing further that the use of nuclear power sources in outer space should be based on a thorough safety assessment, including probabilistic risk analysis, with particular emphasis on reducing the risk of accidental exposure of the public to harmful radiation or radioactive material

In accordance with article VI of the Treaty on Principles Governing the Activities of States in the Exploration and Use of Outer Space, including the Moon and Other Celestial Bodies, States shall bear international responsibility for national activities involving the use of nuclear power sources in outer space, whether such activities are carried on by governmental agencies or by non-governmental entities, and for assuring that such national activities are carried out in conformity with that Treaty and the recommendations contained in these Principles.

In accordance with article VII of the Treaty on Principles Governing the Activities of States in the Exploration and Use of Outer Space, including the Moon and Other Celestial Bodies, and the provisions of the Convention on International Liability for Damage Caused by Space Objects, each State which launches or procures the launching of a space object and each State from whose territory or facility a space object is launched shall be internationally liable for damage caused by such space objects or their component parts. This fully applies to the case of such a space object carrying a nuclear power source on board.

in cases of low-probability accidents with potentially serious radiological consequences, the design for the nuclear power source systems shall, with a high degree of confidence, restrict radiation exposure to a limited geographical region and to individuals to the principal limit of 1 mSv in a year.

Radioisotope generators shall be protected by a containment system that is designed and constructed to withstand the heat and aerodynamic forces of re-entry in the upper atmosphere under foreseeable orbital conditions, including highly elliptical or hyperbolic orbits where relevant. Upon impact, the containment system and the physical form of the isotope shall ensure that no radioactive material is scattered into the environment so that the impact area can be completely cleared of radioactivity by a recovery operation.

Nuclear reactors shall use only highly enriched uranium 235 as fuel. The design shall take into account the radioactive decay of the fission and activation products.

The term "general concept of defence-in-depth" when applied to nuclear power sources in outer space refers to the use of design features and mission operations in place of or in addition to active systems, to prevent or mitigate the consequences of system malfunctions.

This is primarily for Calliban - comments by other forum members are welcome ...

Every morning, while doing forum updates, I set up a view of the Panama Canal operations on a spare monitor. The Canal is in the news these days, because rains have been insufficient to replenish the supply of water needed to carry ships through the older canal locks. The new locks are designed to re-use the water they consume, so waste is greatly reduced.

I've been pondering what it would take to provide sea water to refill the canal when conditions such as the current ones exist. Ships are having to wait extended periods, or to pay large sums to jump the line. It seems to me that those auction fees would amount to a tidy sum. $1,000,000 is at the low end of the scale.

The need for water at the Canal is not constant ... rains normally provide all the water that is needed. One solution might be a nuclear power ship, such as the Russians have in their active fleet, and the Chinese are reported to be building. At one time, the US had a nuclear powered ship (the Savannah if I recall correctly) but it was intended as a showpiece for the US Atoms for Peace program sponsored by President Eisenhower.

What might be an opportunity is development and deployment of a nuclear powered ship with sufficient capacity to power the pumps needed at the Panama Canal to meet worst case needs, and to power entire cities when disaster strikes, as seems quite likely as we look to a more thermally active planet.

As a reminder, it is given as an estimate that 50,000,000 gallons of water are lost for each ship that makes the six lock transit of the canal.

Google found an estimate of 55,000,000 gallons in a citation from ABC News https://abcnews.go.com/international/story (6 days ago so late August)

The total number of gallons that would be needed would be the sum of all the transits that might occur if the locks were fully utilized.

News reports seem to agree on about 40 ships passing through the canal per day, but this figure would include the new locks, which do not lose water.

If sea water can be used, it greatly simplifies the problem. It becomes a simple problem of pumping sea water into some sort of holding tank or dam. Water can then be distributed by gravity, simply by opening and closing valves and sluices and allowing it to drain into the locks using reinforced concrete pipes or spillways.

There are many technologies that could provide the power needed for pumping. One of those Russian floating powerplants would do nicely, but that would be politically impossible right now. As the need for pumping is intermittent and is only required if rainfall is low, I would suggest something with low capital cost. Nuclear reactors are good if you want 24/7 power. But for more occasional use, I would suggest gas turbines or diesel engines, burning a fuel that is storable for long periods between use. Diesel, kerosene or heavy oil would work. LPG is an option as well. LNG is not suitable for obvious reasons. A steam plant is something I would avoid as well. If it is sitting idle and cold for months or even years between use, corrosion could become a serious problem. So for an occasionally used system, nothing works better than gas turbines.

From the information you have provided and what I can glean from the wiki page, you need a system that can pump 2 billion gallons aday, through a head of 26m.
https://en.m.wikipedia.org/wiki/Panama_ … Map_EN.png

That is 7.52billion litres of water. Total pumping energy needed would be: 7.52billion x 9.81 x 26 = 1.92TJ per day. That is a constant power of 22.3MW over a 24 hour period. As GTs go, that is quite small. GTs in this power range tend to be used in coal power stations to allow a black start. With so many coal plants shutting down in the US, you could probably buy one cheaply and install it of a barge. Most of the GTs are old and are adapted from aircraft jet engines. Thermal efficiency will be about 30%. There are dedicated natural gas burning GTs that do much better than that. But if this is a system that only gets used occasionally, you want a solution that has low capital cost and can sit there for months between uses. Aggregate fuel use won't be an issue, but that fuel needs to sit in a tank for a long time without degrading. So an old powerplant GT burning kerosene is probably the best solution.

If you want a system that can provide reliable power to Panama City as well as power the lock system, then the solution may be different. Panama City has a population of 1.5 million. Therefore, two 440MWe RR SMRs or 10 x 77MWe Nuscale SMRs would do the job. The power requirements of lock pumping (22.3MWe) are only a few percent of the combined power output of these units. I would suggest that during times where seawater pumping is needed, some sort of load shedding arrangement can be used. Certain industries receive cheaper power if they agree to be cut off when lock pumping is needed. As we are talking only a few percent total supply, it only needs to work for a minority of power consumers. The other option would be to run the plants at 97% most of time and increase power to 100% when pumping is needed. Or to run the plants at 100% full time and pump the seawater at night. This solution might work well, because grid power demand is always slightly lower at night. If we can build tanks or dams to store seawater as a higher head than the locks, then most pumping can be done at night using excess nuclear electricity. The tanks become a sort of pumped energy storage system.

For Calliban re #145

Thank you for taking up the opportunity that may exist, for Panama to improve it's circumstances, and specifically to improve it's reliability when rains do not fall.

Of all the choices your listed, the one about running the reactors at a percentage of full capability during the part of the year when pumping is not needed is the one that seems most insightful to me. The nuclear fuel will not be diminished by running at less that full throttle. Instead, it will be preserved.

Regarding the reservoir above the locks ... I understand you are one of the many forum members who have not had occasion to study the canal in great depth, as I have done simply because I became interested/enthralled by the impressive web cams (and numerous videos and text presentations) that the Canal Authority provide for web site visitors.

The reservoir you were describing is a body of water that stretches across the Isthmus of Panama at the elevation you quoted from the Wiki article. The canal was excavated by the French, and later by the US. It connects to Lake Gatun on one end, and it is supplied by runoff from the terrain along the path during the rainy season. In fact, on occasion there is so ** much ** runoff that an overflow spillway is designed into the system.

Accordingly, the proposal I am making is to pump sea water up at one or both ends of the canal, to replenish the water lost by ship transits.

Because the canal is replenished by natural rain fall, there is no risk that sea water would contaminate the water inland. The flow of fresh water will always exceed the pumped water , so the pumped water will flush back down the locks as fast as it is pumped up from the sea.

I very much like your suggestion that the best plan for Panama would be one that envisions steady power for Panama City (on the Pacific side) and Colon on the Atlantic side.

The issue at hand is not a technical one. As you noted, fossil fuel can be used to lift water from the sea. For whatever reason, this option has NOT been pursued by the Panama Canal Authority.

What the Panama Canal Authority ** DID ** is instructive. When they borrowed funds to build the new larger locks, they designed the larger locks to NOT waste water. Instead, the water is pumped up into large reservoirs adjacent to the new locks when the ship is descending, or when the level in a lock is lowered to meet a vessel that is ascending, and allowed to flow back into the locks when lifting the water level is called for.

I haven't seen figures for losses of water using this system. I'm sure there must be ** some ** losses, but whatever they are, they are trivial compared to the old locks. My proposal is an attempt to address the water waste designed into the old (original (US designed)) locks, which have been in service since 1914, so well over 100 years.

The problem at hand is a human one ... I'd use the word "political" but the word has been contaminated in recent times....

The process by which humans arrive at a collective decision, without coming to blows, or insulting each other, or generally acting like idiots, deserves a word that is not contaminated.

We need such a process in many aspects of our civilization, and it is pretty obviously in bad shape around the world right now.

The leadership of Panama would include the leaders of the state, and of the cities and counties, and the leaders of the Panama Canal Authority, and the funders who would be asked to pick up the tab for the project.

If there is a way to present a solid plan to address the needs of the people of Panama by investing in nuclear reactors that can pass muster for 100 years of service, I sure would like to see it.

For Calliban re Panama Canal ...

Here is a link to an article about the recent Canal expansion project:
https://www.mayerbrown.com/-/media/file … /12289.pdf

I skimmed the article, and picked up impressions of the thought that went into organizing the effort

Much of the work was done by the Canal Authority in house, and much was contracted out.

I note just one detail ... In seeking bids for excavation of material for the new locks, the Canal Authority was able to provide a wealth of data about the terrain to be modified, thanks to core samples and actual excavation history.

The article mentions risk mitigation frequently.

The impression I get is that this multi-million dollar project was well managed at every stage, and if there were setbacks, they were overcome without fanfare.
