>...Does anyone honestly think the United States has institutions sound enough to safely manage nuclear power over multiple decades?

All indications are that much was learned by industry and the NRC after TMI: "...The NRC said the TMI accident also led to increased identification, analysis and publication of plant performance information, and recognising human performance as “a critical component of plant safety”. Key indicators of plant safety performance in the US have improved dramatically. Those indicators show:

• The average number of significant reactor events over the past 20 years has dropped to nearly zero.

• Today there are far fewer, much less frequent and lower risk events that could lead to a reactor-core damage.

• The average number of times safety systems have had to be activated is about one-tenth of what it was 22 years ago.

• Radiation exposure levels to plant workers have steadily decreased to about one-sixth of the 1985 exposure levels and are well below national limits.

• The average number of unplanned reactor shutdowns has decreased by nearly ten-fold. In 2007 there were about 52 shutdowns compared to about 530 shutdowns in 1985."

No one ever promised that there would never be a nuclear accident - that would be unrealistic for any power source. But historically nuclear power has been much safer than all the alternatives that have been available. If only other power sources were as safe:

Unfortunately anything at all related to nuclear is covered by the media orders of magnitude more than other power sources so many people have an understandable misperception that it is more dangerous than other sources of power. 200 thousand people had to be evacuated in CA a couple of years ago because of a lack of maintenance on a hydroelectric dam could have let to catastrophic failure. We got lucky that time as the rains stopped just in time, but how much did the media cover that story? How much would the media have covered that if 200 thousand had been evacuated because of a nuclear power plant?

A recent Harvard study shows that pollution from fossil fuels is much worse than previously thought and they estimate that it is responsible for more than 8 million people yearly. We need to move away from burning fossil fuels and we need to use all the tools that are available.

It is possible there will be some major advances in grid storage that will allow us to stop using natural gas to cover for the intermittent nature of wind and solar. In that case - great! But... what if that doesn't pan out? The dangers we are facing in the coming decades are immense. Texas has shown us what happens with even a small disruption of energy. If it came down to a situation where you were forced to choose, would you prefer the world to suffer through catastrophic climate change rather than use nuclear power?



> the intermittent nature of wind and solar

is kinda dependent on your region.

where I live, wind is pretty unreliable except at a narrow band of latitude.

but solar is -very- reliable. more like regular than intermittent. So we have two kinds of storage requirements: short term buffers for 15 mins of passing cloud cover, and overnight. Because of this manageable profile our economy is swiftly ramping up solar not just for current demand but in pursuit of 10x cheap new power to drive new industry.


It isn't as easy as you are implying. Trying to rely only on intermittent power sources has huge storage requirements due to weather along with daily/seasonal variation. If grid energy storage was a simple problem it would have been done decades ago.

For example, one estimate is that for Germany to rely on solar and wind would require about 6,000 pumped storage plants which is literally 183 times their current capacity: >...Based on German hourly feed-in and consumption data for electric power, this paper studies the storage and buffering needs resulting from the volatility of wind and solar energy. It shows that joint buffers for wind and solar energy require less storage capacity than would be necessary to buffer wind or solar energy alone. The storage requirement of over 6,000 pumped storage plants, which is 183 times Germany’s current capacity, would nevertheless be huge.

There is a large variation in daily electrical usage (particularly in summer months). For example in the US: https://www.eia.gov/todayinenergy/detail.php?id=42915

Contrary to what advocates claim, people have been looking at grid energy storage for decades and it isn't as simple as they claim. As Bill Gates said in an interview: "…They have this statement that the cost of solar photovoltaic is the same as hydrocarbon’s. And that’s one of those misleadingly meaningless statements. What they mean is that at noon in Arizona, the cost of that kilowatt-hour is the same as a hydrocarbon kilowatt-hour. But it doesn’t come at night, it doesn’t come after the sun hasn’t shone, so the fact that in that one moment you reach parity, so what? The reading public, when they see things like that, they underestimate how hard this thing is. So false solutions like divestment or “Oh, it’s easy to do” hurt our ability to fix the problems. Distinguishing a real solution from a false solution is actually very complicated."

Gates is investing in 4th gen nuclear and energy storage companies so he is putting his money where his mouth is.


> It isn't as easy as you are implying.

I'm not saying it's easy, I'm saying it's happening.


>...I'm saying it's happening.

Hopefully someday, but it's not happening yet. Those big battery farms installed by Tesla (et al) are used primarily for grid stabilization. Most current grid storage is pumped hydro and that has limited potential to expand. Like I said, it is possible there will be some major advances in grid storage that will allow us to stop using natural gas to cover for the intermittent nature of wind and solar. In that case - great! But... what if that doesn't pan out? The dangers we are facing in the coming decades are immense. Texas has shown us what happens with even a small disruption of energy. If it came down to a situation where you were forced to choose, would you prefer the world to suffer through catastrophic climate change rather than use nuclear power?


I'm no power engineer, I'm just assuming that the people pouring literally $billions into huge-scale solar infra in my region know what they're doing.
