Danube Water Level Drop May Affect Operation of Paks Nuclear Power Plant

Hungarian Prime Minister Magyar stated after inspecting the Paks Nuclear Power Plant that the Danube water level has dropped again, which may lead to a further reduction in the plant's power output next week, or even pose a risk of shutdown. At a press conference, Magyar said that about a week ago, heavy rainfall occurred in the Austrian catchment area, temporarily alleviating the low water level of the Danube, but the positive effects of the rainfall have since diminished. According to forecasts, the Danube water level may drop to -132 cm on August 16 or 17, a level approaching the critical operating conditions of the Paks Nuclear Power Plant. If this level is reached, one of the two currently operating turbines may need to be shut down again. He noted that existing forecasts cover the next 6 to 7 days,...

Danube Water Levels Recover, Hungary Restarts Second Turbine at Paks Nuclear Power Plant

On August 10, as the Danube River's water levels recovered, Hungary began restarting a previously constrained turbine at the Paks Nuclear Power Plant. The Paks plant uses Danube water for cooling and normally supplies nearly half of Hungary's electricity. Due to heatwaves and persistent drought, the Danube's water levels fell to historic lows in recent weeks, reducing the plant's generating capacity to about 10%, with only one of its eight turbines remaining operational. According to available information, Hungarian Prime Minister Péter Magyar stated on the 10th that the Danube's water level had risen 19 centimeters from the low point recorded last week, and that restart work on the second turbine at the Paks plant had begun, with power generation expected to resume by Monday evening.

Zaporizhzhia Nuclear Power Plant to Raise Spent Fuel Pool Water Levels to Mitigate Power Outage Risks

The International Atomic Energy Agency (IAEA) stated that the operator of the Zaporizhzhia Nuclear Power Plant has decided to raise the water levels in the spent fuel pools on site to enhance safety buffer capacity in the event of a prolonged loss of external power. The primary purpose of raising the water levels is to extend the time before water in the spent fuel pools begins to boil and evaporate under extreme conditions where external power to the plant is interrupted for an extended period, diesel reserves are depleted, and emergency diesel generators can no longer supply power to the cooling systems. Spent fuel pools are used to store used nuclear fuel underwater, typically for at least five years, allowing its radioactivity and residual heat to gradually decay, making continuous cooling a critical element of nuclear safety. All six units at the Zaporizhzhia Nuclear Power Plant...
