Mo production at the new J-PARC facilitySugihara, Kenta*; Meigo, Shinichiro

Japan relies on imports for the supply of Mo/
Tc used in nuclear medicine examinations. However, due to the short half-life of Mo and its dependence on overseas conditions, domestic production is desirable. The 
Mo(n,
) method at JRR-3 is a candidate, but JRR-3 has a four-month shutdown period for maintenance, and a supply must be covered during that period. Therefore, a conceptual design for Mo production using a 0.4 GeV proton-induced nuclear reaction was developed at the new J-PARC facility, with the aim of covering the supply during the shutdown period. Additionally, we compared the Mo yield immediately after irradiation at the JRR-3 irradiation facility and discussed its usefulness at the new J-PARC facility and future challenges.
