The report BNWL-2041 was prepared by Battelle-Northwest Laboratory for the U.S. Nuclear Regulatory Commission to aid in the assessment of the safety margin provided by the CRBRP transient performance design criteria. The report compares certain aspects of the fuel pin transient performance analysis in the CRBRP PSAR with experimental test results obtained with the Fuel Cladding Transient Tester (FCTT) on EBR-II irradiated fuel pin cladding. Failure temperature, residual strength, and failure strain values obtained by the FCTT are used in BNWL-2041 to question the CRBRP fuel pin design temperature limits for upset and emergency events, the residual strength values employed in the Cumulative Mechanical Damage Function (CDF), and the allowed incremental strain during upset and emergency events. This paper critically reviews the evaluations in BNWL-2041 to assure that FCTT results are correctly analyzed, interpreted, and applied.
