The proposed Technical Specifications for the Noninterruptible Control Air System, in most cases, explicitly applied the current requirements implicit in the Technical Specification definition of OPERABILITY by refering to the 'Ibchnical Specifications for systems supported by the Noninterruptible Control Air System. Further, the request proposed additional allowed outage time beyond the current requirements whenever a Control Air Compressor is inoperable and the associated subsystem receives air through a cross-tie from the other subsystem.
The additional time was proposed to reflect Fermi 2 design features which are not adequately a3 dressed by the definition of OPERABILITY.
