South China Regional Office of the National Nuclear Safety Administration Completes Refueling Outage Inspection of Yangjiang Nuclear Power Plant Unit 2

The South China Regional Office of Nuclear and Radiation Safety Supervision of the Ministry of Ecology and Environment successfully completed the nuclear safety supervision and inspection of the first criticality control point for the eighth refueling outage of Yangjiang Nuclear Power Plant Unit 2 on October 11. After verifying item by item the prerequisites for reactor recriticality and confirming that the primary loop and related systems and equipment were in a controlled and compliant state, the supervisors signed off and released the criticality control point in accordance with the law, marking the successful completion of the on-site nuclear safety supervision task for the Y208 refueling outage of the unit. During the overlapping period of the 2026 Mid-Autumn Festival and National Day holidays, multiple operating units at several nuclear power bases along the South China coast successively entered routine refueling outage cycles, with on-site maintenance activities highly concentrated, and nuclear safety...

Fuel unloading completed for Unit 3 of Dukovany Nuclear Power Plant

On July 30, Unit 3 of the Dukovany Nuclear Power Plant completed the unloading of reactor fuel assemblies, and the planned refueling outage has now entered its next phase. During this outage, the plant will replace part of the nuclear fuel and carry out hundreds of inspections, tests, and maintenance activities to enhance nuclear safety levels and ensure the long-term stable operation of the unit. In this outage, although the actual number of fuel assemblies to be replaced accounts for about one-fifth of the total, operators must first remove all fuel assemblies from the entire core and transfer them to the spent fuel pool. Subsequently, the reactor water level will be lowered to create conditions for maintenance of core cooling system components and inspection of some primary circuit equipment...
