Nuclear reactors can last up to 80 years. The main reason nuclear hasn't displaced fossil fuels over the last 70 years is due to relentless irrational opposition.
> No reactor has yet even reached the operating age of 60 years. That 80 years number is wholly speculative.
Ontario's Bruce A site (Units 1-4) have an age of ~45 years, and has just finished refurbishment (ahead of schedule and under budget) to run for another few decades:
Maybe, but the world is changing. What is safer: some nuclear incidents once in a while, or +4 degrees in the world and a whole strip of land around the equator becoming unlivable to the human species? We're talking billions of refugees here.
I think we need to realise how bad the situation is and how worse it is going to be before we say that nuclear energy is "risky".
The American regime has recently solved this problem by removing safety requirements - they have de-recognized the linear no-threshold model of radiation damage, which means the official fact is that there is a threshold of radiation that's safe to receive. That threshold is, of course, just above whatever one of the nuclear reactors they're about to build will emit. They removed the "as low as reasonably possible" design goal which means it's now allowed to dump radioactive waste into a river to save money
"They removed the "as low as reasonably possible" design goal which means it's now allowed to dump radioactive waste into a river to save money"
This is just an incredibly stupid lie that completely destroys your credibility.
The ALARA (As Low As Reasonably Achievable) principle paired with hyper-sensitive detection technology requires nuclear operators to spend billions on redundant safety features and extensive permitting for infinitesimal health benefits. This regulatory burden prices nuclear energy out of the market.
"safe" is a spectrum. While coal is allowed to kill millions of people a year, the safety level of nuclear in the US was raised to "no matter whatever happens no one ever anywhere must have harm come to them" and that's not realistic. Solar kills orders of magnitude more people than nuclear! But we haven't regulated rooftop solar out of existence, plus that wasn't even an option 50 years ago. That's 40 years we didn't have to be poisoning the Earth with coal.
Thankfully the US has now removed the linear no threshold model and the As Low As Reasonably Achievable radioactive emissions goal which were irrational and made nuclear much more expensive than it should be.
