Description
Summary:Problems that arose around the weld joint connecting the reactor coolant circuit’s header to the steam generator shell during operation of steam generators at nuclear power stations equipped with VVER-1000 reactors are considered. Works on studying the defects occurred in the header’s metal are described, and ways for preventing their development are determined.
