Content:
LOCA. Also to be considered are other accidents involving various high-energy pipe ruptures. Loads induced on the containment by such accidents include elevated temperatures and pressures and possibly localized loads such as jet impingement and associated missile impact. Also included are external pressure loads generated by events inside or outside the containment. f. Those loads to be sustained, if applicable, after abnormal plant conditions, including flooding of the containment subsequent to a LOCA for fuel recovery. g. Those hydrodynamic loads which are associated with BWR suppression pool swell phenomena and are produced as a result of the purging of air and steam in the drywell and vent system into the subversion pool during a postulated LOCA and/or the actuation of safety relief valve (SRV) discharge. Such loads include bubble pressure, bulk swell, and froth swell loads, drag pressure, pool boundary chugging loads, and other pool well loads associated with these phenomena. Also, those loads which are resulting from fluid-structure interaction due to seismic and/or pool swell should be considered. h. Those loads which are generated as a result of platform deformation and flexibility, towing of the platform, and wave action in case of floating plants. Other loads associated with the nonsymmetric dynamic loads generated from LOCA and SRV actuation loads should also be considered. i. Those loads which are generated as a result of the LOCA in the ice-condenser. These loads are categorized as nonsymmetric dynamic transient pressure loads 3.8.2-5 DRAFT Rev. 2 - April 1996 which in the first few seconds might produce compressive stresses in the containment due to the differential pressure across the containment. j. Those loads that are generated as a result of an inadvertent full actuation of the postaccident inerting hydrogen control system (assuming carbon dioxide), but not including seismic or design basis accident loadings.
