The Nuclear Reddit
Nuclear power is the use of sustained nuclear fission to generate heat and electricity. Nuclear power plants provided about 5.7% of the world's energy and 13% of the world's electricity, in 2012. In 2013, the IAEA report that there are 437 operational nuclear power reactors (although not all are producing electricity), in 31 countries. More than 150 naval vessels using nuclear propulsion have been constructed.

RULES
1) Do not encourage/show dangerous DIY methods.
Do not ever post content that shows or encourages users to attempt "at-home" or "DIY methods of obtaining, using, or creating radioactive or other harmful chemicals.
This results in a week long ban the first time with removal of content, and an instantaneous permanent ban the second.
2) Do not violate Reddit's Content Policy.
3) Address the argument, not the person.
Any use of prejudice/discrimination directly against a user (racism, etc) is not acceptable and will result in an immediate ban.
4) Do not make false claims against another user.
Any use of unprovoked ad-hom attacks or accusations to discredit the user will be met with a ban. We do not support arguments that devolve into trying to discredit the other. Keep the conversation about the facts/articles provided in discussion.
5) Do not re-post content.
All content that has already been posted in the past will be removed immediately.
More than 3 offenses results in a ban.
6) Do not post click-bait that fails to source.
Any content posted that fails to source any portion of the article will be subject to removal.
Continuing this practice will result in a talk with the user, with failed adherence afterwards resulting in a ban.
7) Do not spam articles or comments.
Whether pro-nuclear or not, we do not appreciate constant spamming of articles or comments on this sub.
8) Nuclear/renewables fighting
Posts encouraging or highlighting competition between nuclear and renewables are discouraged. Posts calling for the elimination of renewables will be removed. Note this applies to posts and not comments. Comments are more opinion and not considered a sanctioned message of the subreddit.

Serbian president's appeal as country targets four SMRs

Wouldn't it make sense for the US Navy to fund development of higher temperature reactors like liquid metal, molten salt and gas cooled reactors along with supercritical CO2 power cycles and to meet their own needs? Why hasn't the US Navy done it?
When it comes to molten salt and liquid metal reactors I'm not thinking of breeder reactors. I'm thinking of reactors that would use uranium-235 as their fuel because it would be simpler and more compact for use on a ship. Make them thermal spectrum reactors so they don't have to be huge. If uranium-233 or plutonium-239 are used as fuels then they should be bred in separate breeder reactors on land. The same applies to gas cooled reactors.
For supercritical CO2 power cycles I'm thinking of using one of the simpler cycles shown here because the equipment can generate the same amount of power in less space than power generation with steam.
It makes sense to me for the US Navy to pay the first mover costs to develop these technologies to meet its own interests, just like when it did the same to develop the first pressurized water reactors. Why hasn't it been done?
It's not due to worse leadership. Admiral Rickover led the development of nuclear powered ships and launched the first nuclear powered ship, the Nautilus in 1954. He stayed in the Navy leading its naval reactors division until 1981, plenty of time to develop new kinds of reactors and power cycles. Especially with how military R&D is so much better funded than civilian R&D. The disparity was even stronger during the Cold War.
edit. The mentality of not developing new technologies is incredibly disappointing. It should always be developed and improved regardless of any clear, immediate problem even if it is only to prevent stagnation and maintain the ability to improve the technology.

UAE participate in Nuclear Energy Summit in Brussels
Suhail bin Mohammed Al Mazrouei, Minister of Energy and Infrastructure, led the UAE delegation at the inaugural Nuclear Energy Summit in Brussels, convened by the Belgian government and the International Atomic Energy Agency (IAEA). The summit, co-chaired by Belgian Prime Minister Alexander De Croo and IAEA Director General Rafael Mariano Grossi, emphasized nuclear power's integral role in sustainable development. Building upon the momentum from its inclusion in the Global Stocktake at COP28 in Dubai, leaders from 32 nations endorsed measures to expand nuclear capacity, affirming its significance in reducing greenhouse gas emissions and advancing clean energy transition.
