Abstract

The invention relates to an operation method under a radioactive condition, provides a feeding method of a radioactive material liquid and aims at solving the defects of high cost, difficulty of replacing and repairing a feeding pump and low radioactive safety of operators in a current feeding method of a radioactive material liquid. The method comprises the steps of (1), setting a non-radioactive container and filling deionized water in the non-radioactive container; (2), arranging a sealed middle container, filling ionized water in an inner lower part of the middle container and filling an organic solvent in an upper part of the middle container; (3), arranging a sealed feeding container and filling the radioactive material liquid in the feeding container; (4), arranging a feeding pump and a pipeline; and (5), opening the feeding pump to feed the material. Due to the feeding method of the radioactive material liquid, quantitative feeding of the radioactive material liquid is realized, so that the cost of the feeding pump is greatly reduced, the feeding pump is easy to replace and repairing; and the feeding method is good, so that the generation of radioactive waste is reduced; a device used in the feeding method is simple and easy to operate.

Description

technical field [0001] The invention relates to an operation method under radioactive conditions, in particular to a feeding method of radioactive material liquid. Background technique [0002] In the field of nuclear industry (such as nuclear fuel reprocessing), the transportation and transfer of radioactive materials usually need to be completed by using feed pumps. During the feeding process of the radioactive feed liquid, since the feed pump needs to be in direct contact with the radioactive feed liquid, the feed pump will be subject to radioactive contamination and radiation damage. In this case, in order to meet the anti-radiation performance, the cost of the feed pump will inevitably rise sharply; at the same time, due to the existence of radiation shielding equipment and radioactive contamination, the replacement and maintenance of the feed pump will also be very difficult. And it is not conducive to the radiation protection of operators. [0003] Based on the abov...
