THERMAL RADIATION SHIELD FOR SPACE NUCLEAR POWER PLANT Russian patent published in 1995 - IPC

FIELD: nuclear power engineering. SUBSTANCE: known shadow radiation shield of space nuclear power plant that has container in the form of conical shell with bottoms potted in lithium hydride which forms, upon hardening, solid monolith, fastenings mounted on bottoms and used for attaching the shield to other units of nuclear power plant, and power elements inside monolith fastening these parts together, as well as shell-mounted fastenings for power plant service lines is provided with ridges made on conical shell along its generating line and fastenings made in the form of perforated shaped ribs on its inner surface, at points where fastenings of service lines are located. EFFECT: improved service life of radiation shield or equivalent reduction of its mass due to elimination of clearance between shell and hardened lithium hydride monolith, elimination of members projecting beyond shadow cone formed by lithium hydride monolith. 3 dwg
