ENCLOSURE FINAL (SUPPLEMENTAL) RESPONSE TO NRC-0IE LETTER FROM C. E. MURPHY 20 H. G. PARRIS DATED JANUARf 14, 1981 Referencas: (1) Report Nos. 50-518- 80-24 and 50-520/80-24 (2) L. M. Mills' letter to J. P. O'Reilly dated February 6, 1981 As indicated in our initial response (Reference 2) to the inspection report violation in Reference 1, we are including the resolution of GE actions concerning handling ECN's and updating drawings as additional steps taken to avoid further noncompliance.

4. Steps Taken to Avoid Further Noncompliance GE has responded to TVA's request regarding treatment of ECN's and has agreed to implement the practice of encircling the area of :nodification on the ECN to improve the visual identification of affected change areas. Additionally, GE has ensured TVA that C. F. Braun does review ECN's to the same criteria as they review drawings. This is necessary because in the C. F. Braun ddcument control program, ECN's are the documents which directly change a drawing and are not the implementing tool for development of changes. C. F. Braun engineering personnel responsible for sign-off of ECN's have been instructed to ensure that all ECN's are legible when reviewing the ECN for release.
