Rostekhnadzor, Russia's Federal Environmental, Industrial and Nuclear Supervision Service, issued decade-long operating certificates for Zaporizhzhia Nuclear Power Plant units 1 and 2 in early April. Rosatom, the Russian state nuclear corporation, has separately confirmed the reactors cannot be restarted while fighting continues.
The regulatory decision sits alongside the plant's deteriorating physical situation, with the main high-voltage feeder still disconnected and the thirteenth total power loss detailed in event 3. The certification does not change the daily operational problem. It changes the horizon. An earlier IAEA-brokered local ceasefire in April had reconnected the backup feeder , but no sixth ceasefire for the main line has been agreed.
The two Russian actions, operational caution and administrative commitment, are not in tension. Rostekhnadzor's paperwork asserts long-horizon control regardless of military or diplomatic reversals. Rosatom's restart refusal avoids the international safety argument that would come with attempting cold start-up during active fighting. The combined posture treats the plant as a Russian nuclear asset permanently and a cold asset temporarily. Anything a negotiated settlement delivers on Ukrainian territory now has to reckon with a regulator that has already issued paperwork committing Moscow to administer the plant through 2036.
