LIQUID METAL COOLED CORE REACTOR WITH CORE SUPPORT STRUCTURE RELEASED BY HEAT TENSIONS.

摘要

1. A liquid metal-cooled core reactor of the so-called pool type a) having a grid plate (8) which carries the reactor core (5) and which rests on a core-supporting structure (15) which is supported on the base of the reactor tank (1), b) a space surrounded by the core-supporting structure (15) and which is connected to the suction chamber of the cooling medium pumps (9) which contains cooled cooling medium, c) a collecting device which serves to receive a cooling medium sub-stream which serves to hold down the core elements (6, 7) in the grid plate (8), and the walls of which device do not form part of the core-supporting structure (15), d) a cooling medium space which extends from the collecting device to those regions of the wall of the reactor tank (1) which are to be cooled, _c_h_a_r_a_c_t_e_r_i_s_e_d_ _i_n that e) the core-supporting structure (15) contains openings (16) to the suction chamber of the cooling medium pumps (9) which contains cooled cooling medium, f) a special collecting vessel (12) is connected to the collecting device, and g) cooling medium pipelines (13) extend from the collecting vessel (12) to those regions of the wall of the reactor tank (1) which are to be cooled.
