多瑙河水位持续下降至历史最低水平，对沿岸国家的能源供应和运输造成严重影响。布达佩斯7月30日测得的水位仅为23厘米，低于2018年前纪录33厘米[1]。在此背景下，匈牙利和罗马尼亚的核电站被迫大幅削减产能。
匈牙利帕克斯核电站应对措施最为严峻。该电站2号反应堆在7月30日早晨减产50%，1号反应堆已于周一减产254兆瓦，3号反应堆在周三关闭[1]。罗马尼亚切尔纳沃达核电站面临类似困境，一个反应堆在本周早期关闭，第二个反应堆在能源部考虑关闭后最终保持运行[1]。
低水位问题不仅影响核电运营，还对多瑙河航运造成瘫痪。塞尔维亚诺维萨德河段水位下降20米，数百艘小船和数十艘货轮搁浅[1]。保加利亚维丁地区也在周二从搁浅游轮撤离186名游客[1]。与此同时，极端热浪在欧洲多国肆虐，德国疾病控制与预防中心公布数据显示，今年夏季因热相关条件导致9800人死亡，超过2016年以来任何整个年份的死亡人数[1]。
Record-low water levels on the Danube River have prompted Hungary and Romania to significantly reduce nuclear power generation. [1] Hungary's Paks Nuclear Power Station reduced output at its Unit 2 reactor by 50 percent on the morning of July 30, following a 254-megawatt reduction at Unit 1 on Monday and the shutdown of Unit 3 on Wednesday. [1] In Romania, the Cernavoda Nuclear Power Station shut down one reactor early in the week, though a second reactor remained operational after the energy ministry considered closure. [1]
The water crisis extends beyond energy production to critical river transportation. Budapest recorded a water level of just 23 centimeters on July 30, falling below the previous record low of 33 centimeters set before 2018. [1] In Novi Sad, Serbia, the Danube's water level dropped 20 meters, leaving hundreds of small boats and dozens of cargo vessels stranded. [1] Bulgaria's port city of Vidin evacuated 186 passengers from a grounded river cruise ship on Tuesday. [1] The drought conditions have also triggered a severe heat wave across Europe; Germany recorded 9,800 heat-related deaths during the summer, exceeding the total for any full year since 2016. [1]
