e following: (a) Design-basis LOCA in combination with OBE (if E # one- third E’, only its contribution to cyclic loading needs to be considered) D + L + Ta + Ra + Pa + E 3.8.2-14 Revision 2 - March 2007 (b) Operating plant condition in combination with OBE (if E # one-third E’, only its contribution to cyclic loading needs to be considered) D + L + To + Ro + Po + E (c) Operating plant condition in combination with OBE and multiple SRV actuations (if E # one-third E’, only its contribution to cyclic loading needs to be considered) D + L + Ts + Rs + Ps + E (d) Design-basis LOCA in combination with a single active component failure causing one SRV discharge D + L + Ta + Pa + Ra + Ts + Rs + Ps (3) Level C Service Limits These service limits include the loads subject to Level A service limits plus the additional loads resulting from natural phenomena for which safe shutdown of the plant is required. The loading combinations corresponding to these limits include the following: (a) Design-basis LOCA in combination with SSE D + L + Ta + Ra + Pa + E' (b) Operating plant condition in combination with SSE D + L + To + Ro + Po + E' (c) Multiple SRV actuations in combination with small- or intermediate-break accident and SSE D + L + Ta + Ra + Pa + Ts + Rs + Ps + E' (d) Dead load plus pressure resulting from an accident that releases hydrogen generated from 100-percent fuel clad metal-water reaction accompanied by hydrogen burning (10 CFR 50.34(f)(3)(v)(A)(1), 10 CFR 50.44) D + Pg1 + Pg2 Note: In this load combination, Pg1 + Pg2 should not be less than 310 kilo Pascals (kPa) or 45 pounds per square in gauge (psig). 3.8.2-15 Revision 2 - March 2007 (e) Dead load plus pressure resulting from an accident that releases hydrogen generated from 100-percent fuel clad metal-water reaction accompanied by the added pressure from postaccident inerting, assuming carbon dioxide as the inerting agent (10 CFR 50.34(f)(3)(v)(A)(1)) D + Pg1 + Pg3 Note: In this load combination, Pg1 + Pg3
