SUBJECT:

Duke Energy Corporation (DEC)

Catawba Nuclear Station Units 1 and 2 Docket Nos. 50-413 and 50-414

-TAC Nos. MA4315 and MA4316 Proposed Technical Specification (TS) Amendments TS 3.3.1 - Reactor Trip System Instrumentation TS 3.3.2 - Engineered Safety Feature Actuation System Instrumentation TS 3.3.5 - Loss of Power Diesel Generator Start Instrumentation TS 3.3.6 - Containment Purge-and Exhaust Isolation Instrumentation TS 3.4.12 - Low Temperature Overpressure Protection System Pursuant to 10CFR50.90 and 10CFR50.4, this letter submits a license amendment request (LAR) for-the Catawba Nuclear Station Facility Operating License (FOL) and Technical Specifications /

(TS). This amendment is applicable to Facility Operating Licenses NPF-35 and NPF-52.

The changes proposed by DEC in this LAR will facilitate treatment ,

of the-Reactor Trip System (RTS) Instrumentation, Engineered Safety Feature Actuation System (ESFAS) Instrumentation, Loss of fdp/ ,

Power T>iesel Generator Start Instrumentation (LOP), Containment /

Purge .ind Exhaust Isolation Instrumentation (VP), and the Low Temperature ~ Overpressure Protection System (LTOP) power operated relief valves (PORV) TS Trip Setpoints as nominal values.

Currently, the instrumentation Trip Setpoints specified in the subject TS's contain inequalities. It is Duke Energy's position that these ineqanlities do not represent absolute limits for the as-left condition of these setpoints. Instead,- the setpoints and their associated' inequalities are nominal values which allow the trip setpoints-to be left at the value specified in the TS's plus

( or minus an instrument calibration setting tolerance. As

-described in previous correspondence from DEC to the NRC dated August 20, 1998 and September 30, 1998, this position-is supported by the licensing basis for the Catawba Station and the

regulatory positions used to develop the licensf g basis.

However, DEC recognizes that the subject TS's could be revised to-remove any ambiguity as to ?!hether the specified trip points represent absolute or nominal values. Consequently, this LAR will change the subject TS's to provide clarification that the specified' ,tpoints represent nominal values.

L Attachment 1 provides marked up pages of the existing Catawba TS's and. Bases showing the proposed changes. Attachment 2 contains the new Catawba TS and Bases pages. The Description of Proposed Changes and Technical Justification is provided in Attachment 3. Pursuant to 10CFR50.92, Attachment 4 documents the

-determination that this proposed amendment contains No L Significant Hazards Considerations. Pursuant to 10CFR51. 22 (c) (9 ) , Attachment 5 provides the basis for the categorical exclusion from performing an Environmental

, Assessment / Impact Statement. Implementation of this amendment to l the Catawba FOL and TS's will not impact the Updated Final Safety e Analysis Report (UFSAR).

. Note that on March 15, 1999, DEC submitted a LAR for Catawba which proposed to delete TS 3.3.7 for the Control Room Area Ventilation System Actuation Instrumentation, and TS 3.3.8 for the. Auxiliary Building Filtered Ventilation Exhaust' System Actuation Instrumentation. Therefore, it is not necessary to include revised pages for TS's 3.3.7 and 3.3.8 as part of this LAR package.

In accordance with Duke internal procedures and the Quality Assurance Program Topical Repert, this proposed amendment has been previously reviewed and approved by the Plant Operations Review Committee and the Duke Corporate Nuclear Safety Review Board. During NRC review of this LAR, Catawba will continue its current-practice of treating the subject Trip Setpoints as nominal values and leaving these setpoints at the value specified in the TS's plus or minus an instrument calibration setting tolerance.

Pursuant to 10CFR50.91, a copy of this LAR is being forwarded to the appropriate South Carolina state official.

Please direct questions on this LAR to L. J. Rudy at 803-831-L  : 3084.
