Current status of spent fuel isotopic composition database SFCOMPO and related technical development by JAEA

Suyama, Kenya; Okuno, Hiroshi ; Uchiyama, Gunzo

In the field of criticality safety evaluation of spent fuels, Japan Atomic Energy Agency (former Japan Atomic Energy Research Institute, JAERI) has carried out continuous research and development. The effort includes obtaining isotopic composition data of spent nuclear fuels by the post irradiation examinations (PIE) for spent fuels irradiated in light water reactors and developing burnup calculation code system SWAT and new libraries for ORIGEN2 code adopting latest nuclear data libraries. JAERI had developed isotopic composition database SFCOMPO. This report describes current status of SFCOMPO and a result of technical developments of burnup credit in JAEA, i.e. re-evaluation of burnup values of PIE data taken at JAERI.
