Refined Analysis of Effects on the LOFT Containment Building Resulting from Main Steam and Feedwater Breaks

摘要

Dynamic one-degree-of-freedom analyses of main steam breaks 8/10B and 8/11 and feedwater break 9/40 were performed using refined jet-plus-reaction force-time functions. Feedwater breaks 10/8B and 10/11 were analyzed statically using a refined maximum jet-plus-reaction force and assuming a dynamic load factor of 2. None of the breaks were found to stress the containment shell in excess of the ASME Boiler and Pressure Vessel Code allowables. (ERA citation 04:046648)
