Letter from Hal B. Tucker to HR Denton (USNRC), September 26, 1983, Response to Generic Letter 82-33 (Rev. 2) (Supplement I to NUREG -0737) regarding the Catawba Station conformance to Regulatory Guide 1.97, Rev. 2.CATAWBA NUCLEAR STATION REGULATORY GUIDE 1.97, REV. 2 REVIEW iE17 Variable: Range: Category: Existing Design: Compliance:

Display: Position: Implementation Schedule: Atmospheric Stability-50 to 10 0 C 3 The Indicated range for atmospheric stability is"4o to 80C for a 30 meter interval.This instrumentation is In compliance with Duke's Interpretation of RG 1.97, Rev. 2 as clarified in Section 5.5.One computer point.One channel recorded This instrumentation was specified to have an accuracy of +/-0.1 0 C which is considered adequate for the intended monitoring function.Not Applicable.

5-_4 Revision 2 Attachment B -Revised Commitment Wording: Proposed new wording for Regulatory Guide 1.97,Rev 2 -Supplement 1 NUREG-0737 Response and Instrumentation E-17 in UFSAR Table 1-11 and Section 2.3.3.3 E-17 Variable: Range: Category: Existing Design: Compliance:

Display: Position: Atmospheric Stability-50 to 10 0 C 3 The indicated range for atmospheric stability is -4° to 8 0 C for a 50 meter interval.This instrumentation is in compliance with Duke's interpretation of RG 1.97, Rev. 2 as clarified in Section_1.8.1.29.1, with the exception of the instrument accuracy.One computer point. One channel recorded The instrumentation loop has an accuracy of+0.27 0 C through and including the digital or analog display. This minimum loop accuracy is considered adequate for the intended monitoring function of dose assessment.
