Refuelina Information JULY 1985 i
Unit 1 The unit was shut down on March 19, 1985, and remains in cold shutdown i
because of unfinished modifications to meet environmental concerns. The unit began its sixth refueling on June 1, 1985. This refueling will involve loading 838E (retrofit) fuel assemolles into the core, replacing recirculation piping work on "A" and "B" low-pressure turbine, upgrade hangers and anchors, and environmentally qualify instrumentations.
4 There are 764 assemb1'les in the reactor vessel. The spent fuel storage pool presently contains 252 EOC-5 assemblies, 260 EOC-4 assemblies. 232 50C-3 assemblies, 156 50C-2 assemblies, and 168 EOC-1 assemblies. The present fuel i
pool capacity is 3,471 locations.
Unit 2 Unit 2 was shut down for its fifth refueling outage on September 15, 1984,
{
with a scheduled restart date of December 15, 1985. This refueling outage will involve loading additional.8x8B (retrofit) assemblies into the core, finishing torus modification, turbine inspection, piping inspection. TNI-2 modificationst post-accident sampling facility tie-ins, core spray change-out, and feedwater sparger inspection.
l There were no assemblies in the reactor vessel. At month end, there were 1
i 273 new assemblies, 764 EOC-5 assemblies, 248 EOC-4 assemblies, 352 50C-3 assemblies, 156 EOC-2 assemblies, and 132 EOC-1 assemblies in the spent fuel i
storage pool. The present available capacity of the spent fuel pool is 77 j
locations. All old racks have been removed from the pool and new HDRs are being i
installed.
