The purpose of this trip was to discuss with the Licensee, VEPCO, FRC's initial review of the Licensee ts Radiological Effluent Technical Specifica-tions (RETS) submittal for both North Anna and Surry Power Stations.

The intent was to resolve most of the technical difficulties, deficiencies, deviations, and specifications not addressed, with NUREG-0472, Rev. 2 serving as a model RETS.

This also included review of the Offsite Dose Calculation Manual (ODCM) which was submitted by the Licensee for review.

At the onset of the site meeting, WM (NRC) gave to the reviewers a copy of the Rev. 3 (draft) RETS Model NUREG-0472.

Rev. 3 was addressed as a package to be used by the reviewer but copies were made and passed out to the Licensee representatives.

The first station for which review was made was North Anna Units l

& 2 RETS.

The Licensee was informed that Rev. 3 could be used as the model RETS to be followed for comparison purposes.

The two ODCMs; North Anna and Surry, were reviewed as a single review and the.outcome of that discussion was to apply to Surry, as both methodology and equations were very similar.

Due to the fact that the North Anna RETS submittal followed the model RETS NUREG-0472 and the Surry RETS submittal followed existing plant Technical Specifications and a style of their own procedural approach, each review will be discussed separately.

NORTH ANNA POWER STATION (NAPS)

The meeting to review the NAPS RETS & ODCM submittal was held May 12-13, 1982 at VEPCO Corporate Headquarters, Richmond, VA.
