An evaluation is presented of the thermal gradients in LOFT containment vessel for new conditions. The new conditions are, (a) the outside air temperature in buildings attached to the outside of the containment was reduced from 50/sup 0/F to -20/sup 0/F, and (b) the LOCE conditions for inside the containment were reduced from one where T/sub max/ = 260/sup 0/F to one where T/sub max/ = 175/sup 0/F. The four areas considered in this evaluation include all areas affected by the surrounding buildings air temperature change and include (a) the railroad door frame, (b) portions of the stiffener ring, (c) containment vessel shell, and (d) penetrations and air locks.
