IRRADIATION TARGET FOR PRODUCING MO-99 ISOTOPE IN HEAVY WATER REACTOR

WIPO Patent Application WO/2022/167007

A1

The present invention provides an irradiation target for producing a Mo-99 isotope in a heavy water reactor, comprising: a plurality of fuel elements, each comprising a cladding, a uranium-containing core, and an end plug. An end part of the cladding is provided with a filling opening. The end plug covers the filling opening at the end part of the cladding, and is in sealing connection with the cladding. The uranium-containing core is filled in a sealed cavity formed by the end plug and the cladding. A plurality of fuel elements are provided. End plates are arranged at both ends of the fuel elements and are fixedly connected to the plurality of fuel elements. The uranium-containing core of at least one of the fuel elements is an uranium-containing core provided with a rich uranium fuel, and the 235 U enrichment degree of enriched uranium fuel is 6.0 wt% - 20.0 wt%. By means of the present invention, existing reactors may be utilized for non-stop production of Mo-99 having a short half-life. By using enriched uranium to produce Mo-99, the efficiency is high and the quality is good. Meanwhile, effects on power generation of a nuclear power plant can be reduced to a maximum extent.
