Installation of key components of the core catcher for Unit 4 of Leningrad NPP Phase II completed
The under-construction Unit 4 of Leningrad NPP Phase II has recently reached a key engineering milestone: the engineering team of the general contractor TITAN-2 successfully positioned and secured the maintenance platform and cantilever truss of the core catcher (the core passive safety system molten core retention device) precisely in the reactor shaft. The two large components weigh 78 tonnes and 148 tonnes respectively. Following the installation of the first batch of components (the catcher vessel and internal filler materials) in the summer of this year, another breakthrough has been achieved in the assembly of large structures for this core safety facility. As the core barrier of the defense-in-depth system of the Generation III+ pressurized water reactor (VVER-1200), the core catcher is mainly used under severe accident conditions...

Rosatom Starts Preparations for Long-Lead Equipment Contracts at Primorskaya NPP
The engineering division of Rosatom recently announced that preparations for signing long-lead equipment manufacturing contracts for the Primorskaya Nuclear Power Plant have commenced, covering the reactor building, turbine hall, core catcher, and other major system components. According to the announcement, the scope of contract preparation includes key equipment such as main reactor building equipment, turbine hall equipment, the Automated Process Control System (APCS) for the units, and the core catcher. Long-lead equipment typically has extended manufacturing cycles and represents a critical element that must be secured early in the pre-construction phase of a nuclear power project. Currently, the project is also advancing multiple public tender preparation efforts, including site vertical layout planning,...
