FIELD: heating.
SUBSTANCE: invention relates to the recovery heat treatment of units of water-to-water power reactors (WTWPR). The method of recovery of physicomechanical properties of the material of intra-housing devices of the water-to-water power reactor after the action of operational factors includes extraction of the intra-housing devices from the reactor housing and their subsequent heat treatment providing heating, conditioning and cooling, heating is conducted up to the temperature of 975-1025°C, conditioning is performed at this temperature within 120-130 h, and cooling is conducted in air.
EFFECT: increase of the service life and ensuring the safe operation of VVER-1000 reactors.
