ENCLOSURE 2 DESCRIPTION AND JUSTIFICATION FOR CHANGES . ~ya e No. DESCRIPTION/JUSTIFICATION OF CHANGE/SAFETY EVALUATION 89 (units 1 & 2); Change the designation of Traversing-Incore-Probe 90 (unit 3) (TIP) actuation logic from Group 2 to Group 8. This discrepancy was discovered in an internal TVA audit by TVA staff. This discrepancy is the result of an apparent oversight. It should be changed as indicated to correct the discrepancy, since it is a Group 8 actuation logic ~ 251 & 260 (unit 2); FCV 73-81, the bypass valve around the HPCI steam 263 & 273 (unit 3) supply outboard isolation valve (FCV 73-3), was added to units 2 and 3 during their respective 1980 refuel outages. During quarterly surveillance testing on HPCI isolation valve FCV 73-3 in which the valve is closed and reopened, the steamline downstream from FCV 73-3 is sub)ected to thermal stresses from the closure and subsequent reopening. FCV 73-81 was added to relieve those thermal stresses. This is a one-inch valve. It is an isolation Group 4 valve with a maximum closure time of 10 seconds. 251A, 261A (unit 2) During the 1980 refueling outages on units 2 and 3 263AI 264AA 274A the hydrogen-oxygen analyzer system was replaced (unit 3) with the new Hays-Republic Hydrogen-Oxygen analyzer system. These changes are needed to reflect that new system. The safety evaluation for that new system was done at the time the system was installed, i.e., the refueL outage. 'ALl system 76 (Containment Inerting System) valves added to Tables 3.7.A and 3.7.D) were installed in the plant as part of the new H -0 system.'he tables are updated to reflect plant configuration. 252 (units 1 & 2) ~Chan e: Addition of system enation isolation valves 264 (unit 3) to the drywell air compressors "A" and "B," FCV 32-62 and FCV 32-63 (System 32 - Service Air System) to Table 3.7. A. These valves have been installed in the plant as part of a system modification. The drywell air compressors supply air to the air operated valves in containment. The technical specifications need to be updated to reflect plant configuration.
259 (units 1 4 2) ~Chan e: Addition of vaLves 68-588, 68-523, 68-558 272 (unit 3) and 68-555 (System 68 - Reactor Mater Recirculation System) to Table 3.7.D. Justification: Test connections have been added to allow these valves to be given a Local Leak Rate Test. Addition of these test connections should not have any adverse impact on safety. 262 (unit 2) ~Chan e: Deletion ot'alves 76-215 through 76-252 1'rom 276, 277 (unit 3) Table 3.7.D (System 76 - Containment Inerting System) Justification: These valves were removed from service as part of the removal of the previous hydrogen-oxygen analyzer system and the addition of the new Hays-Republic H -0 2 2 System. This revision to Table 3.7.D is need to accurately reflect plant configuration.}}
