The operation is divided into two phases: "Hydraulic testing and circulation flushing of the primary circuit" and "Hot run".  The tests are conducted without nuclear fuel in the reactor and do not pose any nuclear threat.  Their task is to prepare the power unit for the first criticality, which is scheduled for the end of the year.

The operation is aimed to conduct high-voltage and hydraulic tests of the equipment prior to the final assembly.

The work is under way at level  +7,800 of the first power unit turbine building of the LNPP under construction

The seminar was attended by the representatives of JSC CONCERN TITAN-2, Fennovoima, RAOS Project Oy and the Radiation and Nuclear Safety Authority in Finland (STUK).

Experts of JSC CONCERN TITAN-2, the contracting organization of the LNPP under construction, completed the installation of main and auxiliary equipment of technological systems in the standby diesel-generator station building of the first power unit.
