Abstract

The invention discloses an irradiation target containing Np-237 for producing Pu-238 in a research reactor, comprising a target cylinder and an upper end and a lower end arranged at both ends of the target cylinder, the target cylinder is provided with a cooling function The tall target to be irradiated has good cooling effect and is suitable for the production of Pu‑238 by irradiation of research reactors. The irradiation target of the present invention can irradiate Pu-238, and has high conversion rate and good safety.

Description

technical field [0001] The invention belongs to the field of radioactive isotope irradiation production, and in particular relates to an irradiation target containing Np-237 for producing Pu-238 by using a research reactor. Background technique [0002] Radioisotope batteries (nuclear batteries) have the characteristics of small size, high energy density, long life, high reliability, and not affected by the environment. They can provide energy for spacecraft, microsatellites, and cardiac pacemakers. Pu-238 is the first discovered artificially synthesized plutonium isotope. It has the characteristics of moderate half-life, high power density, and light radiation shielding. It is an ideal radioisotope heat source material. The large-scale preparation of Pu-238 relies on irradiation of the target in the reactor, followed by purification by solvent extraction and ion exchange methods. At present, the two main production methods are: recovery of Np-237 from spent fuel and re-irr...
