Enclosure:

As stated 1

• l Request for Additional Information Application Dated July 9,1998 General Electric Company (Vallecitos Nuclear Center)

Docket 70-754 Please provide the following criticality safety and environmental protection information:

1. Page A-5-4, Appendix A, Section 5.9.2: Correct the references to 10CFR70.24.

Did the, licensee intend to change its commitment regarding the criticality accident alarm .

system for 10CFR70.24 from 70.24(a)(2) to 70.24(a)(1) throughout the license? If so,  ;

correct the first reference from 70.24(a) to 70.24(a)(1).

2. Page A-5-4, Appendix A, Section 5.9.3 (new)[5.9.4 (old)]: Correct the reference to a "subcritical area" definition from Section 3.15 to Section 3.17.

l

3. Page 3-5, Appendix B, Section 3.8: Correct the reference to a "subcritical area" definition from Section 3.16 to Section 3.17.

4. Page 6-9, Appendix B, Figure 6.2: Add the locations of the three detectors around the 3

Radioactive Materials i aboratory to Figure 6.2 (as mentioned in Page 7-6, 1 Section 7.3.10).

1

5. Section 10.1.1 presents the licensee's proposed gaseous stack effluent action levels for the site. Some of the action levels listed are larger than the NRC's 10CFR Part 20  :

release limits. NRC assumes that these action levels are higher than Part 20 limits because the levels are measured at the stack and there would be dilution of these l emissions prior to reaching the site fence line, which is the boundary for the licensee to 1 meet Part 20 limits. However, there is not enough information provided for the NRC to  ;

determine if these action levels are sufficient to prevent gaseous discharges from l crossing the site boundary at levels greater than Part 20 limits. Provide the following i information to justify the request to change gaseous stack effluent action levels for the i site: l l

a) a detailed list of the specific isotopes (e.g., U-235, Pu-241) which are discharged j from the site; b) a detailed list of the specific isotopes (e.g., U-235, Pu-241) which are measured under each of the Gross Alpha, Gross Beta, and Noble Gases parameters; c) the specific information used to determine that the requested stack action levels will assure that the site will meet Part 20 limits (e.g., stack height, distance to fence line, wind rose information, X/O calculations, and dilution factors-enough information should be provided so that the NRC can perform confirmatory calculations); and, d) a written justification for the use of the new action levels and how these action levels will assure that Part 20 limits and, specifically, the 10 mrem /yr dose constraint contained in 10 CFR Part 20.1301(d) will be met.
