SERIAL: NLS-84-455 0CT 2 21984 Director of Nuclear Reactor Regulation Attention:
Mr. D. B. Vassallo, Chief
/
Operating Reactors Branch No. 2 Division' of Licensing
(
United States Nuclear Regulatory Commission Washington, DC 20555 BRUNSWICK STEAM ELECTRIC PLANT, UNIT NO. 1 DOCKET NO. 50-325/ LICENSE NO. DPR-71 REQUEST FOR ADDITIONAL INFORMATION UNIT 1 LOCAL LEAK RATE TESTS
Dear Mr. Vassallo:
As a ' result of. telephone conversations with your staff, Carolina Power & Light Company committed to provide additional information concerning our submittal of September 4,1984 which requested a one-time only deferment of requiral Type B ami C local leak rate tests (LLRTs) for certain valves and penetrations.
Specifically, the following data was requested :
1)
The previous LLRT results for the subject valves.
2)-
An indication of which valves can be testal during plant operation.
3).
The approximate dose received during valve testing.
This information has been compiled ami is provided in Attachment 1.
The dose rates listed in Attachment 1 are for testing performed while shutdown, dose rates encountered while testing at power would be substantially higher.
Aiditionally, although many 'of these tests may be performed at power (as indicatal), most would require placing the system in a limiting condition for operation action statement or would initiate a half scram. We consider such actions to be a greater safety concern than deferral of the LLRT testing for three months. provides additional information regarding programmatic improvements at Brunswick involving the LLRT program.
Should you have further uestions concerning this matter, please contact Mr. John S. Dietrich at 919) 836-6154.
Yours very truly, Ohf0

Summary of LLRT Program Improvements
- Expanded total ISI staff from two to ten people with three solely dedicated to LLRT/ILRT.
- Significantly revised program in 1982 following an extensive review of containment penetrations to incluie a larger number of tests.
- Require performance of prenaintenance LLRTs to determine "as found" containment leakage to more closely monitor valve degradation and overall
, containment integrity.
- Revised maintenance procedures to ensure the requirements for pre-and postmaintenance LLRTs are determined correctly.
- Leakage trends since 1982 (these values are approximate):
Unit 1 Unit 2 1982 120 scfh 145 refh 1983 90 scfh 120 sefh 4
1984 90 scfh*
90 scfh 1
- Not a complete cycle for data; Unit I has basically been at power throsqghout 1984.
- For clarification:
BSEP performs its ILRT at 49 psig and the pass / fail limit is 0.5% wt/ day (L The.375 L is used as the criteria for determining whether the,)LRTs remain a,t the 40-month interval or the shorter r
I 18-month interval.
