Leningrad NPP: Rosenergoatom Director General set a task to increase the performance of preparation works on hydraulic tests at the first power unit with VVER-1200 reactor
To provide the full readiness of the secondary circuit for the beginning of hydraulic tests is the task set before the project office extended team by the Director General of Rosenergoatom Concern Andrey Petrov.
The forthcoming action is the milestone of June and the final stage before the starting of hot trials of the reactor equipment of the first start-up complex of Leningrad NPP under construction.
“To carry out the test we need to provide the secondary circuit containment and complete the welding of about 3.5 thousand erection joints at technological systems involved in these operations.
This is a large amount of work, and to accomplish it we need to massively increase the number of welders and increase our work productivity”, Andrey Yuvenalievich stressed.
Successful hydraulic test of the secondary circuits is the main condition of starting the next stage of commissioning works – the hot trials during which the efficiency of the main and auxiliary equipment and systems of the reactor unit will be checked in design and working modes.
Another key topic of the meeting was the information on readiness of the turbine generator positioning on the turning gear. The specialists of Leningrad NPP under construction have reported that they are planning to carry out these works until the end of this month.
The action must confirm that the turbine and generator assembly are carried out in a good manner and the turbine generator is ready for work.
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.
