sed. (a) If the elastic working stress design methods are used: 3.8.3-17 Rev. 1 - July 1981 (1) D + L (2) D + L + E If thermal stresses due to T and R are present, the following combinations shoulB be algo considered: (3) D + L + To + Ro (4) D + L + To + Ro + E (b) If the plastic design methods are used: (1) 1.7D + 1.7L (2) 17D + 1.7L + 1.7E If thermal stresses due to T and R are present, the following combinations shoulB also Be considered: (3) 1.3 (D + L + T + R) (4) 1.3 (D + L + E + T + R) (ii) For factored load conditions the following load combinations should be considered: (a) If the elastic working stress design methods are used: (1) D + L + To + Ro + E' (2) D + L + Ta + R + Pa (3) D + L + Ta + Ra + Pa + 1.0 (Yr + Yj + Ym) + E (4) + L + Ta +R +P + 1.0 (YP + 1- + Y) +E (b) If the plastic design methods are used: (1) D + L + T + R + E' (2) D + L + Ta + Ra + 1-5 Pa (3) D + L + Ta + Ra 1 25 Pa + 1 0 (Yr Yj +Ym)+. 2 E (4) D + L + Ta + Ra + 1.0 Pa + 1.0 (Yr Y +Y)+1.E In the above combinations, thermal loads can be neglected when it can be shown that they are secondary and self-limiting in nature. In combinations (2), (3) and (4), the maximum values of P T , R , Y Y , and Y , including an appropriate dynamic lea8d fictof, sAAul be useW unless a time-history analysis is per- formed to justify otherwise. Combinations (3) and (4) and the corresponding structural acceptance criteria of subsection II.5 3.8.3-18 Rev. 1 - July 1981 of this SRP section should first be satisfied without Y ,., and Y . When considering these loads, local section stpengyh capacities may be exceeded under these concentrated loads, provided there will be no loss of function of any safety-related system.. For the divider barrier, ice-condenser elements and the Mark III containment drywell, the loading criteria are acceptable if found in accordance with the following: d. Divider barrier As the structural integrity of the divider barrier and, to a certain extent, its leak-tight integrity as well,
