Fusion reactor reaction cladding for producing Pu-238 isotopes

Abstract

The invention relates to a fusion reactor reaction cladding for producing Pu-238 isotopes. The fusion reactor reaction cladding comprises a cladding armor, a cladding first wall, a group of multiplication regions and multiplication regions or more than two groups of multiplication regions and multiplication regions which are arranged in a staggered manner, a graphite moderating layer, a neptuniumtarget layer, a graphite reflecting layer and an outermost shielding layer in the radial direction far away from a source, and a partition plate is arranged between a multiplication region and a multiplication region. According to the reaction cladding provided by the invention, on the basis of meeting engineering requirements, the construction and operation cost of a production process can be reduced, the safety of production facilities and equipment is ensured, and the possibility of potential risks is reduced.

Description

Technical field[0001]The present invention belongs to the technical field of radioactive waste treatment, and is specifically involved in the production of polysetal reactive cladding of PU-238 isotope.Background technique[0002]There are about 95% uranium and 1%, and about 4% of the long life fission products and the secondary element NP, AM and CM, etc. (NP account for 0.1%). Among them, NP-237 is a cracked nucleation material. In the nuclear industrial importance is second only to uranium and plutonium, it can make it produced into a target material in neutron irradiation devices to produce an important alpha radioactive isotope PU. -238.[0003]The -238 (PU-238) is an excellent alpha radioactive isotope energy, which can be used for the isotope battery for artificial satellites and medical cardiac pacemakers. It has high compared to power (5.5W / g), half-life (87.7) Year), gamma radiation is weak and easily implanted. Further, since the PU-238 can also emit an energy of X-rays, it...

Problems solved by technology

However, there are certain safety risks in the production of Pu-238 using the fusion reactor cladding, especially the realization of industrial scale production also has high requirements for the stability of the fusion reactor cladding.

Therefore, providing a fusion reactor reactor cladding that is reasonable, feasible and capable of stably producing Pu-238 is beneficial to solving the problems of safety risks in the irradiation scheme using fission reactors and difficulty in meeting the requirements of industrial scale production.
