Content:
s 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 that 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 submersion 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. The staff will also consider those loads resulting from fluid-structure interaction caused by seismic and/or pool swell. H. Those thermal loads associated with passive cooling of the external surface of the steel containment shell, including consideration of nonuniform distribution in the circumferential and meridional directions (e.g., AP600, AP1000). I. Those loads that are generated as a result of the LOCA in the ice-condenser. These loads are categorized as nonsymmetric dynamic transient pressure loads that in the first few seconds might produce compressive stresses in the containment because of the differential pressure across the containment. J. For an existing plant subject to the requirements of Title 10 of the Code of Federal Regulations, Paragraph 50.34(f) (10 CFR 50.34(f)), those loads that are generated by pressure and dead loads during an accident that releases hydrogen generated from 100-percent fuel clad metal-water reaction and accompanied by either hydrogen burning or added pressure from postaccident inerting (10 CFR 50.34(f)(3)(v)(A)(1)); and those loads that are generated as a result of an inadvertent full actuation of a postaccident inerting hydrogen
