COOLANT FLOW LIMITER RESPONDING TO EMERGENCY DEPRESSURIZATION OF NUCLEAR REACTOR CIRCUIT

摘要

FIELD: nuclear power engineering. SUBSTANCE: aerodynamic-drag blocking element in the form of annular chamber arranged on periphery of inner surface of pipeline and provided with holes in inner wall communicating through check valve with external source of blocking agent in the form of environmentally oriented steam or gas held under pressure equal to at least working pressure within circuit is placed inside circuit pipeline. EFFECT: reduced pressure drop in circuit. 2 dwg
