The Shippingport Atomic Power Station has remained shutdown since February 4, 1974 for repair of the main unit turbine and for modifications for installation and operation of the third nuclear core, the Light Water Breeder Reactor (LWBR) core. During this report period, PWR Core 2, Seed 2 was removed from the reactor vessel and placed in the deep pit storage area. Plant conditions were maintained to support the defueling operation. The 1A, 1C and 1D loops were isolated from the reactor vessel and in a dry layup condition. The 1B loop was open to the vessel for decay heat removal. The reactor pit was flooded for core removal and transfer to the storage pit. Following defueling the pit was drained and decontaminated. Inspection of the reactor vessel was completed. Routine periodic maintenance work continued during the period. Work on the replacement of the 1A and 1D heat exchangers continued. Welding of the risers and downcomers on the 1A heat exchanger was essentially completed. The 1D heat exchanger was removed, a spare installed, and fit up and welding of riser and downcomer pipes initiated.
