atures, and hydrostatic loads such as those present in pressure-suppression containments utilizing water. c. Those loads to be sustained during severe environmental conditions, including those induced by design wind (if not protected by a shield building) and the operating basis earthquake. d. Those loads to be sustained during extreme environmental conditions, including those induced by the design basis tornado (if not protected by a shield building) and the safe shutdown earthquake specified for the plant site.' e. Those loads to be sustained during abnormal plant conditions, which include loss-of-coolant accidents (LOCA). The main abnormal plant condition for containment design is the design basis 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 3.8.2-3 Rev. 1 - July 1981 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
