The hydraulic trials of the 1st power block’s reactor core cooling system have begun at the Leningrad NPP under construction
The team of the Leningrad NPP’s 1st power block under construction has started working on the hydraulic trials of the high-pressure safety injection system.
“The trials run at the return pipes of the first out of four safety channels have proven that those lines are solid and consistent. The welded connections have been done properly, with no leakages, permanent distortions, or metal breaks identified”, Alexey Mochalov, the deputy head of the Leningrad NPP’s reactor hall responsible for installation, commented.
“The technical examination commission and Rostechnadzor have announced that the hydraulic trials were successful. The return pipes are installed in a proper way, in accordance with the project, and operate normally. It is guaranteed that they will run safely and reliably. Similar operations will shortly be held at the pipelines of other safety system channels”, Vitaliy Shutikov, the head of the trials and the head of the Leningrad NPP’s reactor hall, summarized.
The high-pressure safety injection system is one of the protective safety systems designed to transfer boric acid solution into the reactor’s coolant system in case there is an accident involving loss of boric acid solution. It also, along with other systems, facilitates the reactor core’s cooling.
The Leningrad NPP is an affiliate company for Rosenergoatom Concern OJSC. The plant is based in the city of Sosnovy Bor, 40 km to the west from Saint Petersburg at the Gulf of Finland shore. The Leningrad NPP is the first Russian nuclear power plant having RBMK-1000 reactors (uranium-graphite channel-type thermal neutron reactors). The NPP exploits 4 power blocks with the electric capacity of 1000 megawatt each. Also, pursuant to the NPP-2006 project, 1,2 VVER-1200 power blocks included into The State Atomic Energy Corporation ROSATOM long-term plan are being constructed. Rosenergoatom Concern OJSC is the owner and developer of the project. Holding TITAN-2 is the primary contractor. ATOMPROEKT is the general designer.
