INTEGRATED FAST REACTOR Russian patent published in 2000 - IPC

FIELD: nuclear power engineering. SUBSTANCE: each internal structural component 12, 13, 15, 16, 22 of fast reactor is provided with supporting and holding members engageable with at least one component of system that includes reactor main vessel 1 and mentioned internal structural components 12, 13, 15, 16, 22 so as to hold them in position simply by resting on surfaces inside main vessel 1 without welded and mechanical joints. Floor 13 rests on supporting ferrule and flange in part of internal wall of main vessel. Cushion 12 that functions as base of reactor core 11 lies on floor 13. Internal chamber 16 is mounted on floor 13 and rests on bottom part of its internal ferrule 16c. Ferrule 22 that passes liquid sodium for cooling internal wall of reactor main vessel 1 rests with its bottom part on supporting facility of floor 13. Mentioned internal structural components are independent structures distinguished by high-precision treatment which makes them compact. EFFECT: reduced diameter of main vessel and mass of materials. 21 cl, 16 dwg
