Good morning,

Please find below analysis from the DOE/NNSA Ukraine Task Force related to nuclear safety risks resulting from damage to the Kakhovka Dam.

• Th e damage to the Kakhovka Dam creates s ignificant humanitarian ri sks and jeopardizes the long-term operation of Zaporizhzhia Nuclear Power Plant (ZNPP) even if th e Ukrainians are ab le to regain co ntrol, however, there is no immed iate risk to nuclear safety from the lowering water levels.

• The biggest risk to nuclear safety continues to be the single off-site power supply to ZNPP.

Nuclear safety analysis

• Impacts from damage to the Kakhovka Dam have been assessed prev iously, by Ukraine in 20 11 as part of the post-Fukushima 'stress tests' and by the U.S. using Department of Homeland Security (DHS) dam safety modeling software. The Ukrainian analysis was published pub licly and is referenced by many media so urces.

• The U.S. Energy Attache at Embassy Kyiv ha s been in contract with Energoatom (the plant operator), the nuclear regulator, the Ministry of Energy, and the Armed Forces o f Ukraine, all of which report long-term operational issues but no immediate safety concerns.

• IAEA Director General Gross i provided remarks during the ongoing Board of Governors meeting, stating, "our current assessment is that there is no immediate risk to the safety of the planl." The State Depar tm ent repo11s that in addition to hi s published remarks, he added, ' I've been warning about the danger of increased military activity in the region for months and today here we are.' DG Grossi reiterated his plan to travel to ZN PP next week.

• If the water level in the public re se rvoir lowers below intake levels and cannot feed the cooling pond/spray ponds, alternate sources of makeup water wi ll be needed (to replace losses from evaporation, small leaks, etc.)

• U.S., Ukraine, and IAEA analyses arc consistent that the current water avai lable is enough for approximately 4-6 weeks before alternate water so urces may be needed.

Humanitarian conditions

• Th e Armed Fore s of Ukraine report that th po ssib l dama g includes inund atioi..

appro xim a te ly 250 quarc mile w ith a population of92 000 people in 40 e ttl ements.

• Evac uation are underway via bu e, tra ins, and private vehicles.

Please let us know if you have any quest ions.

Thanks (b)(6)
