This report describes the application of ARROTTA, a three dimensional space time kinetics code, to a licensing analysis of the PWR rod ejection accident. Three approaches for the use of ARROTTA are described: (1) a benchmark for point kinetics, (2) direct application as a biased licensing model, and (3) as a best estimate model used in conjunction with statistical combination of uncertainties. The use of ARROTTA as a biased licensing model was fully developed in conjunction with Duke Power Company; the results have been submitted to NRC as part of their reload licensing methodology.
