EVENT DESCRJPTION AND PROBABLE CONSEQUFNCES Oio l o l2 l l0n 12/15/82 at 0936, both the Unit Yturbine driven and the lA motor driven g jojall emergency feedwter pumps (EFWP) were incapable of automatic actuation for 460 l seconds. Since neither were capable of automatic actuation, they were consid-

o;3)lered technically inoperable and constituted a degraded mode. At the time, the l l o l s l lMDEFWP could have been made automatic, the TDEFWP could have been started at thel l o l 7 l l pump, and the 1B MDEFWP could have been used. The health and safety of the l loisllpublic were not iconardized. l
