POOL SWELL a. Bubble pressure, bulk swell and froth swell loads, drag pressure, and other pool swell loads should be treated as abnormal pressure loads, P . Appropriate load a combinations and load factors should be applied accordingly. b. The pool swell loads and accident pressure may be combined in accordance with their actual time-dependent mutual occurrence. 2. SAFETY RELIEF VALVE (SRV) DISCHARGE a. The SRV loads should be treated as live loads in all load combinations with the exception of the combination that contains 1.5 P where a load factor of 1.25 a should be applied to the appropriate SRV loads. b. A single active failure causing one SRV discharge must be considered in combination with the design basis accident (DBA). c. Appropriate multiple SRV discharge should be considered in combination with the small-break accident (SBA) and intermediate break accident (IBA). d. Thermal loads due to SRV discharge should be treated as T for normal operation 0 and T for accident
