Optimization of waste management for mixed oxide fuel in light-water reactors: Evaluation of the effectiveness of blending spent uo2 and mixed oxide fuels in reprocessing

This study evaluated the impact of using mixed oxide fuel in light- water reactors (MOX-LWRs) from viewpoint waste management. As one challenges MOX-LWR is high decay heat, reasonable option for management may be to reduce heat generation high-level radioactive (HLW) glass by blending spent MOX and UO2 fuels. Both thermal properties HLW on repository are examined. The results indicate that introducing blended UO2–MOX (blended HLW) as a technical can control repository, which then lead reduction 5–30% emplacement area. obtained demonstrate viability future alternative approach MOX-LWR.
