Abstract

The thermal stress state of the connecting node of the shank of the spiral coil element ∅ 32×4 mm to the collector ∅ 325×32 mm of HPH-6 and HPH-7 for the operational modes of the power unit with the WWER-1000 reactor is investigated. Mathematical modeling of the connection is performed, taking into account that temperature movements and stresses depend on the thermophysical and mechanical characteristics of structural materials in the operating conditions of the equipment.
