Content:
ion 1 of NUREG-0484 presents guidance on the acceptable methods for combining LOCA, SRV, and the safe-shutdown earthquake (SSE). This report states that the square root of sum of the squares method is appropriate for the following: A. Combination of SSE and LOCA dynamic responses for all ASME Class 1, 2, or 3 systems, components, or supports. For dynamic responses resulting from the same initiating event, when the time-phase relationship between the responses cannot be established, the absolute summation of these dynamic responses should be used.
