This actually happened in August and September of 2023 and it’s great validation for High Temperature Gas-cooled Reactor (HTGR) at larger scales. I hope they have the guts to also do a full loss of coolant test. I’ve also heard the these tw

I have a feeling that in hindsight, 30-40 years from now, this will seem like no brainer and that the period prior was heavily anti-meritocratic and counterproductive.

If the pipeline started operating, which it probably would in a few months with energy catastrophe in Europe - it would be total victory for Russia: natural gas revenues through the roof, end of war, etc etc. USA for some reason believes th

Better metrics -- $/operation which includes the capital and operating cost and expected lifetime of the chip OR $/transistor or something like this.

In some respects, vulnerability to attack is a feature, not a flaw for promoting peace and collaboration instead of violence. A country with nuclear reactors is less likely to piss neighbors off enough to lead to an invasion. If invasion oc

Meltdown accident: basically, reactor is turned off, however heat continues to be generated because of a thing called decay heat which is when isotopes generated by the fission reactions decay to more stable isotopes and release energy. It&

The typical radioisotope generator is a Plutonium-238 source like the MMRTG on the Mars rovers. The Plutonium decays by alpha emission with a half life of 80+ years. The problem is there is a very limited supply of Plutonium-238 - we use th

Regarding Omouamoua, we just observed for the first time in human history, a cylinder or plate shaped object from another star flying through our solar system with questionable orbital velocities (we are not quite sure how to explain a smal

I was going to mention CANDU, basically the only exception to the above comment about running at too high power density.

This is just the dumb/old kind of nuclear in which the reactors are operated at really high power which means they have to be actively cooled so that the fuel doesn't melt itself and cause release of radiation. The reason they run

These guys explicitly want to couple their nuclear plant with wind/solar: https://usnc.com/mmr-energy-system/ . And from top level, it looks a lot like a natural gas plant.

Nuclear detonations are very effective earth movers, perhaps capable tools in an Megascale structure project. See project plowshare. I'm not sure if the energy to make a weapon (enrichment primarily) is less than using conventional dig

Very fair. We should just bite the bullet of Covid. The goal at the beginning was just to prevent overwhelming medical capacity. No one ever signed up to save everyone at the expense of everyone else!

1% of commercial reactors Have failed catastrophically. Seems like terrible track record.
