Zaporizhzhia Nuclear Plant Without External Power for Over a Week as IAEA Warns 10-Day Diesel Supply at Risk

BLUFIAEA will very likely secure continued diesel resupply or a negotiated line repair before onsite fuel runs out around September 8, but drone strikes at the site could collapse that margin without warning.

The Zaporizhzhia Nuclear Power Plant has been without off-site power for more than a week after losing its last remaining line, the 330kV Ferosplavna-1, on August 20 following military activity north of the Dnipro River, IAEA Director General Rafael Grossi said 1. The plant is running on emergency diesel generators to power cooling pumps for its six reactors and spent fuel pools, and as of Friday had approximately ten days of diesel fuel on site, the regulatory minimum 12. The IAEA reported deliveries of several dozen tonnes of fuel from two off-site locations on Thursday and Friday, the plant's first resupply in roughly six months, and said it is negotiating a local ceasefire to allow repairs to the damaged line 123. The IAEA also confirmed three drone incidents at the site during the week, including one that injured two employees near the cooling pond on August 25 1.

Analysis
The plant's ten-day diesel reserve, not the severed Ferosplavna-1 line, now sets the survival clock, and the IAEA will very likely secure a further fuel delivery or a negotiated ceasefire to repair the line before onsite supplies run out by September 8. Confidence is moderate, reflecting the Agency's access for two deliveries this week and six prior ceasefire negotiations, offset by continued military activity and three drone incidents that could disrupt logistics on short notice. Reporting rests on a single primary account, IAEA's own Update 364, with other outlets adding only same-day pickups rather than independent confirmation. The ceasefire framing may overstate near-term prospects, since six prior localized arrangements since late last year have not fixed the plant's external power vulnerability. Whether the margin holds determines whether Western donors keep routing emergency fuel through existing IAEA channels or face pressure to authorize a more forceful ceasefire-enforcement or line-repair mission on compressed notice.
