Dear Sir:

j August 9, 1988. Attached is a revision to the previous proposed amendment to the

, Technical Specifications for Facility Operating License Nos. NPF-35 and NPF-52 f; 1 for Catawba Units 1 and 2. The request involves changing Technical Specification i Table 3.3-3 to reflect a proposed change in the actuation logic for the Nuclear

j requirements to allow for the implementation of this modification. Per the {

4 August 12, 1988 denial letter, the discussion now addresses the safety

! significance of allowing a 48 hour5.555556e-4 days <br />0.0133 hours <br />7.936508e-5 weeks <br />1.8264e-5 months <br /> waiver of compliance with the Action j St .etement . i t t j The attachment contains the proposed change and a discussion of the justification l and a No Significant liazards Analysis. The analysis is included pursuant to 10 l 1 CFR 50.91 and it has been concluded that the propnsed amendment does not involve  !
