On September 1st 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. Mr Vitaliy Polianin, Vice President Director for Belarus NPP construction project said that 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 pre commissioning activities at Unit 1. Tests took a little over one 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.
