On July 27, power unit No.2 of Belarus NPP (its General Designer and General Contractor being ROSATOM Engineering Division) has proceeded to the reactor plant hot functional test, which is the most large-scaled stage of commissioning works before the physical start-up. The permit to carry out this technological process was issued by the Gosatomnadzor of the Republic of Belarus. During the hot functional test, specialists check the operability of the power unit main equipment for meeting the design documentation requirements, including compliance with operation safety standards. All main and auxiliary equipment and the reactor plant systems are tested at the following operating parameters: the primary circuit temperature reaches 280 degree C, while the pressure reaches 160 atmospheres (more than 165.3 kgf /cm2).

Besides testing the primary circuit equipment (such as reactor, steam generators, main circulation pumps, main circulation pipeline, etc.), the specialists will also test safety systems, auxiliary power systems, reactor control and protection systems.
