Idaho National Engineering Laboratory (INEL) used the RELAP5/MOD1.6 code to simulate a number of transient scenarios for the USNRC PTS study of the H.B. Robinson Unit-2 PWR plant. Eleven of these scenarios were reviewed at BNL on the basis of information received before September 30, 1984. Six of these eleven scenarios were selected for an in-depth quantitative analysis performed on the basis of a simple method developed at BNL. However, the detailed analysis of two of these transients, namely transients 1 and 4 are not presented here as they have since been recalculated by INEL and the new calculations could not be reviewed at BNL due to budgetary constraints. The simple method uses the mass and energy balance equations to predict the temperature and pressure of the reactor system. The results of these calculations were compared to the RELAP5 results and the INEL extrapolations. In general, the RELAP5 and INEL results appear to be reasonable.
