Jack Cushing - Doc2.wpd Page 1 I Jack Cushing - Doc2.wpd Page 1 1 REQUEST FOR ADDITIONAL INFORMATION POINT BEACH NUCLEAR POWER PLANT, UNITS 1 AND 2 DOCKET NOS. 50-266 AND 50-301 In reviewing the Nuclear Management Company, LLC's submittal dated July 12, 2007, the NRC staff has determined that the following information is needed in order to complete its review:
Enclosure I Section 1. Summary Description, last sentence in the first paragraph on Page 2 of 9 reads:
The proposed amendment would also support a change to the Point Beach Nuclear Plant (PBNP) Final Safety Analysis Report (FSAR) changing the present penetration classification of "Class 5" to "Special," with the subsequent requirement to leak check the outside-containment purge supply and exhaust valves.
The second paragraph of Section 1 reads:
The proposed amendment would revise leakage testing requirements for the containment purge supply and exhaust isolation function. Leakage of the double 0-ring seals of the blind flanges is addressed by SR 3.6.1.1. The purge supply and exhaust valve system no longer contains the inside-containment isolation valves.
- 1.
What is meant by "...subsequent requirement to leak check the outside-containment purge supply and exhaust valves"?
- 2.
How does the requested deletion of surveillance requirement (SR) 3.6.3.1 revise leakage testing requirements for the containment purge supply and exhaust isolation function? Is this revision in leakage testing requirements implicit in the requested

Type B penetrations are required to be tested under Option B of 10 CFR 50 Appendix J at least once every 30 months.
- 3.
Your Technical Specifications Section 5.5.15a indicates that your Containment Leakage Rate Testing Program is in accordance with Regulatory Guide 1.163, "Pir-ffg-a-te-B6sed-Cdntain-rdent-Leak-TegtProgram."
Regulatcry Guide 1.163 endorses NEI 94-01, Revision 0, "Industry Guideline for Implementing Performance Based Option of 10 CFR 50 Appendix J." NEI 94-01 Revision 0 reads "...periodic Type B tests shall be performed at a frequency of at least once per 30 months, until acceptable performance is established." NEI 94-01 goes on to allow the Type B penetration test interval to be extended up to a maximum of once per 120 months based on the acceptable
Jack Cushing - Doc2.wpd Page 2 1 performance and additional performance factors. The sentence quoted above was not a complete statement of the testing intervals for Type B penetrations. Does the testing interval for the blind flanges still follow the complete guidance stated above or is it limited to 30 months?
