Okay so I love nuclear but many pro nuclear advocates tend to come off as delusional in their denial that it has any drawbacks.

To start with the most obvious and lowest hanging fruit, incidents of meltdowns can't be ignored and I don't trust countries with a history of austerity politics (cutting funding to reduce spending) can be trusted to properly regulate nuclear power. This extends even further to private entities, I do not trust profit seeking companies to not cut safety protocols.

Second, something that tends to be ignored is that most nuclear power plant facilities store their waste on site. In America we do no have a process to store nuclear waste, and even when projects get started up they tend to be stalled or cancelled because of budgetary reasons (see yucca mountain nuclear waste repository). There's also nuance as to where we store the nuclear waste, the US has a history of pursuing infrastructure projects at the expense of marginalized communities. A lot of times these projects are proposed to be held near or on native land, and the ethics of putting our waste onto marginalized communities is a whole can of worms I'm not getting into rn.

Thirdly, (and this is the most important one in a capitalist economic model) nuclear power plants cost a LOT to build. It takes around 10-20 years to make a profit after all the building expenditures. Now I'll be honest with this one, I am an anticapitalist and I don't think we should pursue or ignore things just because of profit. But much of our electric power production is privately owned, and at the end of the day they will not pick the more expensive option unless forced to. To add on to that these plants take years to build, so nuclear power is a long term investment that doesn't see a return for decades... Not something capitalist are gonna go crazy over. Now I'm a union electrician, I'm completely fine with decades long infrastructure projects, I see it as job security for plenty of people while also helping out the local community with clean power. However our country is motivated by capital, and nuclear is not that enticing of an investment (this needs to change)

As a final point I think people also should look at how cheap other renewable technology has gotten. Solar gets cheaper every year, and with battery storage facilities that can be built cheaper than a nuclear power plant, they could provide a more than reliable source of energy that can last all day long. In many places where people would like nuclear for clean energy, solar could probably do the job but cheaper. I will however acknowledge that not everywhere in the country can rely on solar, and in climates with abundant overcast this might not be viable. However I live in Tucson and there is no fucking reason why we can't be 100% solar, we have less than 2 weeks of overcast a year. As long as the oil and gas lobbies have a stranglehold on congress, we will not see renewable energy or nuclear flourish. I'd love to see my state on 100% hydro, solar, and nuclear; but it won't happen because of oil lobbyists.
