First U.S. nuclear reactor built from scratch in decades enters commercial operation in Georgia::ATLANTA — A new reactor at a nuclear power plant in Georgia has entered commercial operation, becoming the first new American reactor built from scratch in decades.

France was able to output 2 reactors per year at 1,5 billion of euros per 1000MW for more than 2 decades during the 70's to 90's. The whole French nuclear industry has cost around 130-150 billions between 1960 and 2010, including researches, build and maintenance of France's whole nuclear fleet.

A 1000MW reactor, at current French electricity price and for a 80% capacity factor, generates 1,4 billion of euros worth of electricity per year, for a minimum of 60 years.

Nuclear is not costly, and can absolutely compete by itself, if you don't sabotage it and plan it right.

Except those reactors are off 30-50% of the time due to shoddy construction, €1.5/W in 2023 money is pure fiction, and overnight costs with free capital aren't real costs once you adjust for inflation and stop cherry picking the first reactors before negative learning rates kicked in.

I would be very interested to know why the trend has moved away from building reactors in time and within a reasonable budget. It seems that most projects after the turn of the millennium haven't been cost effective.

Why did we manage to build reactors well before but not now?

Every year a reactor operates is a year of experiencing new ways they suck. The fixes and added complexities are rolled into the next reactor.

Thr grifters running the show also learn new ways to grift, so the small new delays and costs are amplified.

For older reactors the costs this imposes are rolled into operational budgets (and more often than not reactors are closed as unprofitable and the public or ratepayers are left holding the bag).

Additionally regulatory agencies keep finding new instances of fraud, stopping these adds costs to the regulator and regulatee.

This has happened since well before three mile island, so all misdirections to "scare mongering about meltdowns" are lies (the rate of cost escalation actually slowed significantly after three mile island).
