The spillage phase was carried out in order to check the permeability of the pipelines connecting the primary circuit equipment and their post-assembly cleaning from possible mechanical impurities. During the process, chemically demineralized water was spilled in the system of emergency cooling of the core and pressure compensator, cleaned the pipelines of the purge-make-up system, and flushed the equipment and pipelines of the system of emergency and planned cooling down, passive heat removal system from the core. In total, the process involved 26 technological systems associated with the first circuit.
Currently, experts have begun to build the reactor. These works are carried out in the framework of preparation for the next important stage - hydrotesting and circulation spillage of the reactor compartment pipelines at elevated parameters.
Belarusian NPP with two VVER-1200 reactors with a total capacity of 2400 MW is being built according to the Russian project of generation 3+, which fully complies with international standards and the International Atomic Energy Agency (IAEA) safety recommendations.
