DOI:https://doi.org/10.2172/4132521· OSTI ID:4132521

During the first quarter of 1975, the Shippingport Atomic Power Station remained shutdown for PWR/LWBR (Pressurized Water Reactor/Light Water Breeder Reactor) Core Conversion. Defueling operations continued throughout the quarter. A nitrogen purge of the upper reactor vessel was initiated on January 3, and then on January 10, the reactor vessel water level was lowered to a level between elevation 706'9'' and 707'2''. This level has been maintained the remainder of the quarter. The RWD gaseous waste system remained vented to atmosphere throughout the first quarter report period. (auth)
