The first entry is always the pin's source. Overall confidence is a weighted average of how firmly each reference supports the start and end times used above; a reference counts half as much for every 180 days older than the newest.
Operator confirms December 7 startup, December 23 grid connection and January 10, 2025 commercial return; different from stale database restart marker.
Reactor timeline, electrical capacity and annual electricity supplied; historical table derived from IAEA PRIS.
Published safety-upgrade estimate described for Shimane Unit 2 restart; not the unrelated Unit 3 construction project. Exact quote: “revised that figure upward to 600 billion yen”.
Something missing or wrong? Say it in your own words: a link that backs this pin up, a different start or end date and why, or a fact it lacks or gets wrong. The AI checks it against this pin's sources, searches for better ones, and adds any page that backs you up. The pin's own sources still count most. A picture that shows something else, or shows it badly, is looked at too, and moved down or replaced.
The operator confirms commercial return after receipt of the regulator’s inspection certificate. Net electrical rating 789 MWe; gross 820 MWe.[1]
789 MW electrical capacity. Historical generating capacity; not a claim about current output. Calendar-2025 electricity supplied: 7,072.79 GWh (annual energy, not instantaneous output).[2]
Project cost: JPY 600,000,000,000. Published safety-upgrade estimate described for Shimane Unit 2 restart; not the unrelated Unit 3 construction project. Source quote: “revised that figure upward to 600 billion yen”. Stated currency; no foreign-exchange or inflation conversion.[3]
