Zaporizhzhia nuclear plant has approximately 11 days of diesel fuel left, Rosatom says

BLUFFull replenishment of ZNPP's diesel reserves is unlikely by July 31, leaving the plant operating on thin fuel margins in an active strike zone.

Rosatom chief executive Alexey Likhachev told journalists in Kaliningrad following consultations with an IAEA delegation that diesel fuel reserves at the Zaporizhzhia Nuclear Power Plant stand at roughly 50 percent of required capacity, enough for about 11 days of autonomous operation 123. Likhachev said all tanks need to be filled to maximum capacity to build a larger reserve against unforeseen situations 12. He noted the plant has switched to autonomous power supply 21 times to date, each time without incident, and called energy stability the second-highest item on the agenda after nuclear safety 12. Likhachev also said Ukrainian forces have struck the plant more than 400 times since mid-March, and Kremlin spokesman Dmitry Peskov said Moscow remains in contact with the IAEA over the danger of strikes near the plant 3.

Analysis
Full replenishment of ZNPP's diesel reserves to required capacity by July 31 is unlikely, since tank deliveries require safe passage through a zone Ukrainian forces have struck more than 400 times since mid-March, and Rosatom's push to build reserves beyond the current 50 percent floor depends on logistics neither side has committed to protect. This judgment carries low confidence, resting on Rosatom's own operational reporting rather than independent IAEA confirmation of tank levels or resupply logistics, with the figures converging narrowly across Interfax, Kommersant, and Vedomosti as primary accounts plus one secondary pickup, all from Russian state or state-adjacent media. The quantified 50 percent reserve and 11-day runway mark the first concrete operational metric, superseding May's vaguer warnings of a deteriorating situation nearing a point of no return. The disclosure may function as leverage for securing international logistics access rather than genuine distress, given the plant's clean record across 21 prior autonomous switch-overs; continued shortfall past July 31 would sustain pressure for a negotiated strike-free buffer zone around the plant.
