-DISCUSSION OF PROPOSED TECHNICAL SPECIFICATION CHANGES

-The proposed change to North Anna 1 and 2 Technical Specifications Table 4.11

- 2 will include the Containment Vacuum Steam Ejector (Hogger) as a gaseous

-release path that should be monitored. A containment air sample will be sampled by grab sample and have a minimum analysis frequency of prior to each release, for each ejector. This release path was inadvertently left out of our RETS submittals f of December 16, 1982 and February 25, 1983 and was since approved by the NRC on May 5, 1983, in Amendment Ncs. 48 and 31, for North

. Anna 1 and 2, respectively. Since this proposed change was left cut of our previous submittals, and it should have been included, and it has since been approved by the NRC, the change should be administrative 1y inserted.

The proposed change to North Anna 1 and 2 Technical Specifications 5.1.2 is to indicate that the low population zone is shown in Figure 5.1-2 instead of Figure 5.1-1. Amendment Nos. 48 and 31, for North Anna 1 and 2, respectively, deleted Figure 5.1-2. Figure 5.1-2 should be re-inserted into the Technical Specifications and so indicated in Technical Specification 5.1.2.

The proposed change to North Anna 1 and 2 Technical Specifications Figure 5.1-1 should be revised to include the location of the Met. Tower. The location of the Met. Tower was inadvertently left out of our RETS submittals.

The proposed change to North Anna 1 Technical Specification 4.11.2.5 is to revise the table number that is referenced in the surveillance requirement.

Table 3.3-13 is referenced and the correct table number should be Table 3.3-14.

The proposed change to North Anna 2 Technical Specification 6.10.2n is to make the requirement read, " Records of meetings of the System Nuclear Safety and Operating Committee to issuance of Amendment No. 11." The Amendment No. (11) was inadvertently left off our RETS subm'**21 and has since been approved by the NRC.

These proposed changes do not pose a significant hazards consideration as described in the Federal Register, dated April 6, 1983, Page 14870, Example (1); a purely administrative change to the Technical Specifications: for example, a change to achieve consistency throughout the Technical Specifications. The proposed changes are needed to correct various administrative problems that have developed since our RETS submittals of December 17, 1982 and February 25, 1983 and the issuance of Amendment Nos. 48 and 31, for North Anna 1 and 2, respectively, which dealt with RETS. A number of corrections needed to be made due to inadvertent discrepancies from our RETS submittals N0/JHL: Jab /044-m17
