The Leningrad NPP-2: the installation of automated worksites for operating personnel has been started at the power unit No. 2 of the VVER-1200

At the control unit of the work-in-progress power unit No. 2 with the VVER-1200 of the Leningrad NPP-2, the workers began to install the automated worksites for operating personnel.

They are to install equipment, to connect cables to it, to energize and to perform commissioning operations, and then to carry out overall tests as a part of the process control system.

Automated worksites are critically important. With the help of them, Site Shift Manager and leading engineers responsible for reactor and turbine control will monitor all the processes at the power unit; to measure, to record and to change operational parameters of the unit.

“With modern equipment, you can control the power unit “at single-click ease”. Operating personnel don’t need to go to the site in order to open or to close the valve. The power unit is remotely operated from worksites, with an instant and accurate displaying all the necessary data and parameters on screens”, - Dmitry Marygin, head of the section of thermal automatics and measurement department of the Leningrad NPP-2.

The whole set of works at that equipment will be completed in April in order to settle down the one of milestone events of 2019. That event is spillage of active and passive safety systems to an open reactor. This work is scheduled for the second quarter. During the spillage of systems, the workers will check permeability of primary pipelines. 

The Leningrad NPP is the country’s first plant with RBMK-1000 reactors (uranium-graphite circuit-type reactor running on thermal neutrons). The decision that marked its construction was taken in September 1966 by a resolution of the Central Committee of the Communist Party of the USSR and the Council of Ministers No. 800-252. According to that document, the Leningrad NPP was supposed to become a core in a network of nuclear power plants with RBMK-1000 reactors that were supposed to produce a substantial share of electric power. The construction of the Leningrad NPP was going well, and by 1973 the first power block was fully erected. On December 23, 1973, following stable 72-hours’ operation at the capacity of 150 megawatt, the State Commission signed the acceptance certificate stating that the first power block of the Leningrad nuclear power plant is commissioned for pilot production.
