>If a few nuclear plants could easily be built on budget and on time in a given system, it would not be an issue...
Then it must not be an issue, because the People's Republic of China has been building dozens of nuclear plants on time and on budget for the last decade.
China's new nuclear connections have slowed way down since 2018. Last year, China connected just 1.2 GW(e) of new nuclear to the grid (a 1000 MW PWR and a 200 MW HTGR).
In contrast, they installed 217 GW(e) of PV in 2023.
Authoritarian state still keeping a toe in for military and pragmatic reasons. With communistic 5 year plan system you can through sheer force build a few reactors to keep the option open.
For every passing year they’ve been pulling back their nuclear ambitions in favor of renewables.
Then it must not be an issue, because the People's Republic of China has been building dozens of nuclear plants on time and on budget for the last decade.
