Pressure test of primary circuit pipelines and equipment successfully completed at Belarus NPP Unit 1

Moscow, September 4 - Neftegaz.RU. On 01.09.2019, hydraulic tests of primary circuit systems and equipment for strength and tightness under 24,5 MPa pressure were successfully completed at Belarus NPP Unit 1 (Gen.Designer and Gen.Contractor is ASE, Engineering Division of Rosatom).

High availability of the unit has given us the opportunity to perform the hot pressure test of pipelines and equipment of the primary circuit at A-1 sub-stage ‘Equipment test and trial’ of stage-wise program of the precommissioning activities at Unit 1, noted Vitaliy Polianin, VP-Director for Belarus NPP construction project, ASE.

Tests took a little over 1 day and were performed virtually in the same breath - some minor observations were eliminated in the course of pressure buildup while performing under the program.

Currently, the specialists have begun tests of safety systems for the sealed primary circuit, which were also shifted from A-3.1 sub-stage, then, pipelines and equipment of the secondary circuit will undergo hydraulic tests for strength and tightness under 11,5 MPa pressure, which are scheduled for the first ten days of September.

Belarus NPP equipped with 2 VVER-1200 reactors making 2400 MW in total is being constructed according to the Russian 3+ generation design that fully complies with the safety related international standards and recommendations of International Atomic Energy Agency (IAEA).
