The Novovoronezh NPP: the 3+ generation 6th power block has attained 90% of its capacity

The most potent one in Russia and the world’s first innovative 3+ generation power block of the Novovoronezh NPP has attained 90% of its capacity. Thus, the new 6th power block has moved to the 3rd sub-stage in the pilot production capacity level development, which is the final step to prepare the power block for commercial operation.

It is important to note that the pilot production is an important phase in launching the 6th power block operational, and it is subdivided into the following sub-stages:
  • attaining 50% of the capacity (sub-stage 1);

  • attaining 75% of the capacity (sub-stage 2);

  • attaining the project capacity (sub-stage 3: includes the 90% and 100% capacity trial runs);

  • the acceptance tests of the power block for its commissioning into commercial operation (sub-stage 4).

The power start-up of the 6th power block took place on August 5th, 2016. The Novovoronezh NPP obtained the Rostechnadzor’s approval of launching the pilot production of the 6th power block early September this year, which was followed by the equipment trials in different modes and reaching the 50% capacity.

At the moment, similar tests are carried out at the 6th power block with 90% of its capacity. The plan is being adhered to without any deviations.

The pilot production phase will be completed once the test runs are successful at all capacity levels, including the project capacity (100%) and once the power block passes all acceptance tests. It is planned to be commissioned for commercial operation late 2016.

The 3+ generation power blocks are also being constructed in France and the USA; however, the Novovoronezh NPP’s 6th power block became the first new-generation atomic power block to reach the pilot production stage.

The Novovoronezh nuclear power plant is a branch of the JSC "Concern Rosenergoatom". The station is located on the bank of the Don River in 42 km to the south of Voronezh. It is the Russia's first nuclear power plant with VVER reactors (water-to-water power reactors of case type with regular water under pressure). Each of five reactors of the station can be a main one – a prototype of serial power reactors: the power unit No. 1 with the VVER-210 reactor, the power unit No. 2 with the VVER-365 reactor, the No. 3, 4 power units with the VVER-440 reactors, the power unit No. 5 with the VVER-1000 reactor. The first power unit was launched in 1964, the second – in 1969, third – in 1971, fourth – 1972, fifth – 1979. There are three power units (power units No.1, 2 were stopped in 1984 and 1990 respectively) in work at the moment.

The new innovative power units with capacity 1200 MW have been constructed at the construction site of the Novovoronezh NPP since 2007.
