Refueling Information s,
OCTOBER 1986 Unit 1 e'
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 scheduled restset date to be determined. The sixth refueling will involve loadirs 8x8R.(retrofit) fuel assemblies into the core. The prior-to-startup unit 1 itosas 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-tion of O sonry 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 1
computers, seismic qualifications of piping (IEB 79-02/14), postaccident evaluation (NUREG-0737), RPS modifications (IE Notice 78-45), H 0 sample 22 line modification (LER 81-050), radiation monitors modification (LER 80033),

i
- There are.0 assemblies in the reactor vessel. The spent fuel storage pool presently contaids 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 I
of the fuel pool'.is 1355 locations.
Unit 2
\\
Unit 2 was shut down-on September 15, 1984, for its fifth refueling outage
(
with a echeduled r'estart date to be determined. On September 3, 1985, the unit was placed ori' administrative hold to resolve TVA and NRC safety concerns. The fifth refueling involves loading 8x8R (retrofit) fuel assemblies into the core.
The prior-to-startup unit 2 items are CRD SDIV piping modification (I88-80-17),
environmental qualification of electrical equipment (10 CFR 50.49), torus modifications (NUREG-0661), containment modification (NUREG-0737), electrical changes (Appendix R 10 CFR Sd) (partial), NSIV modifications, modification of masonry walls (IEB-80-11), addition of foedwater nozzle temperature monitoring (NUREG-0619), evaluation of the vent drain and test connections, VDTC, (LER-82020), valve modification (Appendix J) (partial) D/G speed sensor 00278 e-
