3 Refueling Information JANUARY 1986 Unit 1 The unit was shut down on March 19, 9185, and remains in cold shutdown because of unfinished modifications to meet environmental concerns. The unit began its sixth refueling on June 1, 1985. The refueling will involve loading 8x8R (retrofit) fuel assemblies into the core, replacing recirculation piping, work on "A" and "B" low-pressure turbino, upgrade hangers and anchors, and environmentally qualify instrumentations.
There are 764 assemblies in the reactor vessel. 1he spent fuel storage pool presently contains 252 EOC-5 assemblies, 260 EOC-4 assemblies, 232 EOC-3 assemblies, 156 EOC-2 assemblies, and 168 EOC-1 assemblies. The present fuel pool capacity is 3,471 locations.
Unit 2 Unit 2 was placed on administrative hold to resolve various TVA and NRC concerns. The ucit was shut down for its fifth refueling outage on September 15, 1984, with a scheduled' restart date of June 1, 1986. This a
refueling involves loading additional 8x8R (retrofit) assemblies into the core, finishing torus modification, turbine inspection, piping inspection, THI-2 modifications; postaccident sampling facility tie-ins, core spray change-out, and feedwater sparger inspection.
There are no assemblies in the reactor vessel. At month end, there were 277 new assemblies, 764 EOC-5 assemblies, 248 EOC-4 assemblies, 352 EOC-3 assemblies, 156 EOC-2 assemblies, and 132 EOC-1 assemblies in the spent fuel storage pool. The present available capacity of the spent fuel pool is.77 locations. All old racks have been removed from the pool and,new HDRs are being I
installed.
