Progress in extending burnup of LWR fuel

Creators

Description

Progress in increasing burnup of LWR fuel has been and continues to be made. Initially, LWR fuels were designed to achieve a burnup of about 33 GWd/tu for PWRs and about 28 GWd/tu for BWRs. Current warranties are about 36 GWd/tu and 31 GWd/tu for PWRs and BWRs, respectively. Present optimum extended burnups (batch average) are typically about 50 GWd/tu and 45 GWd/tu for PWRs and BWRs on 12-month cycles, respectively, and about 10% higher for 18-month cycles. Thus, the goal of research and development programs of the recent past has been to achieve these burnup levels reliably with maximum duty cycle flexibility
