RELAP5/MOD3 is a pressurized water reactor (PWR) system analysis code being developed jointly by the U.S. Nuclear Regulatory Commission (USNRC) and a consortium consisting of several of the countries and domestic organizations that are members of the International Code Assessment and Applications Program (ICAP). The mission of the RELAP5/MOD3 code development program is to develop a code version suitable for the analysis of all transients and postulated accidents in PWR systems including both large and small break loss of coolant accidents (LOCA's) as well as the full range of operational transients. Although the emphasis of the RELAP5/MOD3 development is on large break LOCA, improvements to existing code models, based on the results of assessments against small break LOCA and operational transient test data, are also being made. This paper discusses the new code models as well as improvements to existing models. 13 refs., 6 figs., 1 tab.
