__________.__._n_. o 2 Operations Summary (Continued) October 1985 Fatigue Usage Evaluation The cumulative usage factors for the reactor vessel are as follows: Location Usage Factor Unit 1 Unit 2 Unit 3 Shell at water line 0.00620 0.00492 0.00430 Feedwater nozzle 0.29782 0.21319 0.16133 Closure studs 0.24204 0.17629 0.14326 NOTE: This accumulated monthly information satisfies Technical Specification Section 6.6.A.17.B(3) reporting requirements. Common System Approximately 1.2E+06 gallons of waste liquids were discharged containing approximately 1.05E-01 curies of activities. l I L @4 k

3 Operations Summary (Continued) October 1985 Refueling Information Unit 1 Unit 1 was in shutdown for its sixth refueling on June 1,1985 with a scheduled restart date of March 1989. 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. The unit was shut down on March 19, 1985, and remained in cold shutdown until June 1,1985, because of unfinished modifications to meet environmental concerns. There are 0 assemblies in the reactor vessel. The spent fuel storage pool presently contains 764 EOC-6 assemblies, 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 shut down for its fifth refueling outage on September 15, 1984 with a scheduled restart date of January 22, 1986. This refueling outage will involve loading additional 8X8R (retrofit) assemblies into the core, finishing torus modification, turbine inspection, piping inspection, TMI-2 modifications; post-accident 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 HDR's are being installed.

4 Operations Summary (Continued) October 1985 Unit 3, Unit 3 is scheduled for its sixth refueling outage approximately i November 30, 1985, with a scheduled restart date of March 1987. This refueling involves loading 8X8R (retrofit) assemblies into the core, and complete reinspection.of stainless steel piping. The unit was shutdown on March 9,1985, I and will remain in cold shutdown until November 30, 1985, on an administrative 1 hold to resolve various TVA and NRC concerns. There are 764 assemblies presently in the reactor vessel. There are 248 EOC-5 assemblies, 280 EOC-4 assemblies,124 EOC-3 assemblies,144 EOC-2 assemblies, and 208 EOC-1 assemblies in the spent fuel storage.Sool. The present available capacity of the spent fuel pool is 914 locations. ? { 4 1 1 1 i i 1 { 4 9
