> I'm not keen on new nuclear (time and cost as much as anything else), but it's a terrible idea to phase out operating nuclear plants which are still safe and within their planned lifetime.

Funnily, I have almost the opposite view. I'm terrified of old nuclear because those first gen power plants are all missing a lot of safety lessons. Nuclear disasters happen at old plants.

I want old nuclear plants to be either upgraded or decommissioned. I have much less concern about new nuclear (other than it taking a very long time and an a lot of money to deploy).

A healthy social attitude to nuclear would be to require periodic upgrades or decommissions as the plant ages.

Nuclear reactors are regularly maintained, tested and checked. When possible, old plants are upgraded to new safety standards.

You can upgrade certain components, and safety systems. However things like the containment structure or pressure vessel can't be changed. You for example can't retrofit a core catcher, but you could improve the turbines, I think Steam Generators as well, replace PLC's, Tsunami proof your site by building a larger tsunami wall / making your backup generators flood proof...

What nuclear disasters? Exactly? Name one nuclear disaster at an old nuclear plant whose lessons weren’t applied to the whole fleet.

> Nuclear disasters happen at old plants.

You used plural? What disasters are you talking about?

Even Chernobyl wasn't technically first generation (not that it has anything to do with power plan safety in western countries anyway).

Three Mile Island kind of proved it was fairly safe given that's the worst disaster to ever happen without any external factors (like tsunamis or being designed and run by soviet engineers..)

safety is great and in some cases it can be improved. check out what great carenage is in france

Even assuming all bad stuff, nuclear is statistically ok https://ourworldindata.org/safest-sources-of-energy

Tell me you don't work in energy without telling me.

Most heavily regulated industry on the planet - constant upgrades and safety reports.
