6 Operati.ons Summary DECEMBER 1986 s
The following summary describes the significant operation activities during the reporting period. In support of this summary, a chronological log of significant events is included in this report.
There were two reportable occurrences and no revisions to previous occurrences reported to NRC during the month.
Unit 1 The unit remained on administrative hold the entire month. The unit is also undergoing its end-of-cycle 6 refueling.
Unit 2 The unit remained on administrative hold the entire month. The unit is also l
undergoing its end-of-cycle 5 refueling.
Unit 3 i
The unit remained on administrative hold the entire month. The unit is also undergoing environmental qualifications to comply with NRC requirements.
This was prepared principally by T. R. Smith.

Refueliin Information
~'
DECEMBER 1086 Unit 1 Unit I 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 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-tion of masonry walls (IRB-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 i

There are 0 assemblies in the reactor vessel. [hespentfuelstoragepool presently contains'284 new assemblies, 764 EOC-6, 252 EOC-5, 260 EOC-4, 232 EDC-3, 156 EOC-2, and 168 EOC-1 assemblies. The present available capacity 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 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 fifth refueling involves loading 8x8R (retrofit) fuel assemblies into the core.
l The prior-to-startup unit 2 items are CRD SDIY piping modification (IEB-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 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, VDTC, (LER-82020), valve modification (Appendix J) (partial), D/G apeed sensor 3
f Refuelina Information DECEMBER 1986 Unit 2 (Continued) installation (LER-81-004), HPCI and RCIC testable check valve change out, modification of PCIS logic (LER 259-85009), HPCI concerns, seismic program i
review, and EECW carbon to stainless pipe change out.
There are 0 assemblies in the reactor vessel. At month end there were 303 new assemblies, 764 EOC-5, 248 EOC-4, 352 EOC-3, 156 EOC-2, and 132 EOC-1 assemblies in the spent fuel storage pool. The present available capacity of the spent fuel pool is 1164 locations. All HDRs have been installed in the pool j
with the exception of two.
Unit 3 Unit 3 was shut down on March 9, 1985, and placed on administrative hold to resolve various TVA and NRC concerns with a scheduled restart date to be determined. The sixth refueling outage has been scheduled for September 21 i
j 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, modification of masonry' walls (IEB-80-11), evaluation of the vent drain and test connections, VDTC, (LER 82020), valve modifications (Appendix J), HPCI
