Refueling Information ..

AUGUST 1986 Unit 1 1

' Unit 1 was placed on administrative hold in March 1985 to resolve TVA and NRC concerns. .The unit also began its sixth refueling on June 1, 1985, with a i scheduled restart date to be determined. The sixth refueling will involve loading 8x8R (retrofit) fuel assemblies into the core. The prior-to-startup unit 1 items _are environmental qualification of electrical equipment (10 CFR 50.49), torus modification (NUREG-0661), containment modifications (NUREG-0737),

electrical changes (Appendix R 10 CFR 50) (all), NSIV modifications, modifica-r tion of masonry walls (IEB-80-11), evaluation of the vent drain and test connections, VDTC, (LER-82020), valve modification (Appendix J), HPCI concerns, modification of PCIS logic (LER 259-85009), replacement of plant process j computers, seismic qualifications of piping (IEB 79-02/14), postaccident I

evaluation (NUREG-0737), RPS modifications (IE Notice 78-45), H22 0 sample i- line modification (LER 81-050), radiation monitors modification (LER 80033,),

-EECW carbon to stainless. pipe change out, and all NRC commitment items except Anticipated Transients Without Scram (ATWS) modifications which is. scheduled for

! next o'utage.

! There are 0 assemblies in the reactor vessel. The spent fuel storage pool-presently contains 284 new assemblies, 764 EOC-6, 252 EOC-5, 260 EOC-4, 232 EOC-3, 156 EOC-2, and 168 EOC-1 assemblies. The present available capacity of the fuel pool is 1355 locations.

i Unit 2 Unit 2 was shut down on September 15, 1984, for its fifth refueling outage

with a scheduled restart date to be determined. On September 3, 1985, the unit was placed on administrative hold to resolve TVA and NRC safety concerns. The j fifth refueling involves loading 8x8R (retrofit) fuel assemblies into the core.

The prior-to-startup unit 2 items are CRD SDIV piping modification (IEB-80-17),

environmental qualification of electrical equipment (10 CFR 50.49), torus modifications (NUREG-0661), containment modification (NUREG-0737), electrical l changes (Appendix R 10 CFR 50) (partial), NSIV modifications, modification of masonry walls (IEB-80-11), addition of feedwater nozzle temperature monitoring (NUREG-0619), evaluation of the vent drain and test connections, VOIC,
