TANK-REACTOR NUCLEAR POWER UNIT (OPTIONS) Russian patent published in 1996 - IPC

FIELD: nuclear power engineering. SUBSTANCE: tank-reactor nuclear power unit incorporating box-mounted vertical cylindrical vessel with core and rounded-off bottom provided with connections, compressed-gas system and device for filling box with liquid has its perforated containment secured in a spaced relation to external part of bottom that embraces its central part within which angle between tangents to bottom and longitudinal center line is not over 65 deg. Containment has connection whose one end is directed to bottom and other one is connected to compressed-air system. In its option, bottom mounts set of elements in a spaced relation to bottom and to each other; inner surfaces of elements are truncated conical surfaces of revolution with their larger base facing bottom and center line aligned with longitudinal center line of vessel; each preceding element is inserted into next one elevated in respect to the preceding one; bottom element has connection one of whose ends is directed to bottom and other one is connected to compressed-air system. EFFECT: improved design. 2 cl, 2 dwg
