requires, in part, that two ECCS injection / spray subsystems shall be operable. - With two -

i required ECCS injection / splay subsystems inoperable, initiate action to restore wolation capability to each required secondary containment and secondary containment bypass '

penetration flow path not isolated.

Contrary to the above, between October 18 and December 16,1997, isolation capability for each required secondary containment and secondary containment bypass penetration flow path not isolated was not restored in that surveillance testing for Containment :

Building Fuel Transfer Pool Ventilation Plenum Radiation - High instruments was not :

performed. Consequenty, Secondary Containment isolation Dampers 1VF04Y, Tuel ,

Buil: ling Supply Outboard Isolation," 1VF06Y, " Fuel Building Supply Inboard Isolation,"

- 1VF07Y,'" Fuel Building Exhaust inboard isolation Damper," and 1VF09Y, " Fuel Building Exhaust Outboard isole, tion Damper," did not have isolation capability.

This is a Severity Level IV Violation (Supplement I).

2. . Technical Specification 3.8.8, " inverters - Shutdown," requires, in part, that in Mode 4,

- one divisional inverter capable of supplying one division of the Division I or 11 onsite Class IE uninterruptible AC bus electrical power distribution subsystems required by ,

- operable. With one or more required divisional inverters inoperable, the limiting P:ondition for operation requires that actions be initiated to declare the affected required features inoperable immediately or suspend core alterations, suspend handling of irradiated fuel s assemblies in primary and secondary containment, suspad operations with the potential to orain the vessel, and initiate actions to restore required divisional inverters to an operable status immediately.

Contrary to the above, from November 8 to December 28,1997, the licensee did not initiate actions to restore required divisional inverters to an operable status immediately.

Specifically, operations personnel failed to note the impact on the Division I and ll inverters after declaring their respective room cooling fans inoperable.
