During the fourth quarter of 1976, the Shippingport Atomic Power Station remained shutdown for PWR/LWBR (Pressurized Water Reactor/Light Water Breeder Reactor) core conversion. The PWR Core remains in storage in the deep pit of the Fuel Handling Canal. The LWBR core barrel has been installed in the reactor vessel. The first core blanket assembly was installed in the core barrel on December 10 and a second blanket assembly was installed December 29. A seed assembly was installed in the core barrel on December 11 and a second seed assembly was installed on December 30. At the beginning of the quarter the 1A, 1B, 1C and 1D reactor coolant loops were drained with a nitrogen purge established. The 1B, 1C and 1D steam generators were in a wet lay-up condition and recirculating on the reactor plant cooldown and temperature control heat exchanger. The 1A steam generator was in a partial drain condition with a nitrogen purge established. The pressurizer was drained and isolated from the reactor vessel.
