3 Refueling Information NOVENBER 1985 Unit 1 The unit was shut down on March 19, 1985, and remains in cold shutdown because of unfinished modifications to meet environmental concerns. The unit began its sixth refueling on June 1, 1985. This refueling will involve loading 8x8R (retrofit) fuel assemblies into the core, replacing recirculation piping work on "A" and "B" low-pressure turbine, upgrade hangers and anchors, and environmentally qualify instrumentations.
There are 764 assemblies in the reactor vessel. The 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 was placed on administrative hold to resolve various TVA and NRC concerns. The unit was shut down for its fifth refueling outage on September 15, 1984, with a scheduled restart date of June 1, 1986. This refueling involves loading additional 8x8R (retrofit) assemblies into the core, l
finishing torus modification, turbine inspection, piping inspection. TNI-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 273 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 installed.

4 Refueling Information NOVEMBER 1985 Unit 3 Unit 3 started its environmental qualification outage to comply with NRC requirements December 1, 1985, with a scheduled restart date of March 1987. The unit was shut down on March 9, 1985, and remained in cold shutdown until December 1, 1985, on administrative hold to resolve various TVA and NRC concerns. The sixth refueling outage has been scheduled for September 21, 1988, and involves loading 8x8R (retrofit) assemblies into the core and'ATWS modifications. The prior-to-startup unit 3 items are environmental qualifica-tion of electrical equipment (10 CFR 50.49), containment modifications (NUREG-0737), electrical changes (Appendix R 10 CFR 50) (all), NSIV modifica-tions, modifications of masonry walls (IE8-80-11), evaluation of vent drains and test connections, VDTS, (LER 82020), valve nod 1f1c,ations (Appendix J), HPCI concerns, replacement of plant process computer, seismic qualifications of piping (IEB 79-02/14), postaccident evaluation (NUREG-0737), addition of redundant drywell control air supply, RPS modification (IE Notice 78-45),
4 H0 sample line modification (LER 81-050), radiation monitor modification 22 (LER 80033), replacement of jet pump holddown beam assemblies (IEB-80-07),
change out switches in SBGT (LER-83-018), EECW carbon to stainless pipe change out, and plant design upgrade to seismic qualification.
There are 764 assemblies presently in the reactor vessel. There are 248 EOC-5, 280 EOC-4, 124 EOC-3, 144 EOC-2, and 208 EOC-1 assemblies in the spent fuel storage pool. The present available capacity of the fuel pool is 914-locations.
