The invention discloses a vacuum chamber with neutron moderation, neutron shielding and cooling functions. A wall of the vacuum chamber adopts an inner and outer wall interlayer welding structure, wherein the wall comprises a vacuum chamber inner wall and a vacuum chamber outer wall; the vacuum chamber inner wall and the vacuum chamber outer wall are welded into a whole, and an interlayer is formed between the vacuum chamber inner wall and the vacuum chamber outer wall. Before welding, a metal ceramic composite neutron absorbing material used for absorbing neutrons is placed in the interlayer,a neutron moderating coolant inlet is formed in the lower left portion of the outer wall of the vacuum chamber, and a neutron moderating coolant outlet is formed in the upper right portion of the outer wall of the vacuum chamber. An interlayer between the inner wall of the vacuum chamber and the outer wall of the vacuum chamber is filled with a liquid neutron moderating coolant. The vacuum chamber can be in any shape, such as a common square or cylindrical vacuum chamber; through the design, it is guaranteed that the vacuum chamber has the neutron moderation function, the neutron shielding function and the cooling function in the thermal state, and the vacuum chamber stably can work for a long time in the internal neutron radiation state and the thermal state.
Description
technical field [0001] The invention belongs to the field of separation of nuclear materials, and in particular relates to a vacuum chamber with functions of neutron moderation, neutron shielding and cooling. Background technique [0002] In the field of nuclear material separation, in addition to good vacuum sealing performance, the vacuum chamber also needs to slow down and shield the neutron radiation in the vacuum chamber, and cool the wall of the vacuum chamber. However, conventional vacuum chambers do not have this function. Therefore, it is necessary to design a vacuum chamber with functions of neutron moderation, neutron shielding and cooling. Contents of the invention [0003] Aiming at the defects existing in the prior art, the object of the present invention is to provide a vacuum chamber with reasonable structural design and strong practicability, which has the functions of neutron moderation, neutron shielding and cooling. The sub-radiation is moderated and ...
