Dear Mr. Denton:

The recently submitted Amendment Number 20 to the Vogtle Electric Generating Plant (VEGP) Final Safety Analysis Report (FSAR) contained an error in regard to Regulatory Guide 1.94. Paragraph 1.9.94.2, VEGP Position, clarification number 9 " Paragraph 7.5 Welding" included the phrase "of structural steel not in tension". This erroneously limits our commitment to use of the Visual Weld Acceptance Criteria (VWAC) by excluding those welds which are in tension.

This is not our intent.

Attached is a marked up copy of page 1.9-74b indicating the deletion of the phrase. We will correct this error in the next general amendment to the VEGP FSAR.

If you have any questions in this regard, please do not hesitate to contact me.

I urs truly, l

This paragraph requires visual inspection on completed splices shall be performed only after the splices have cooled to ambient temperatures. The VEGP specification does not require splices to be cooled to ambient temperature prior to inspection.
