Request for License Amendment for TS Surveillance Requirements for CS Nozzles - Dated 4/19/02 Following is the list of questions we would like to discuss with you on the subject amendment for Byron/Braidwood Units 1 and 2. Please let me know about your availability to have this telephone conference. If you have any further questions, please give me a call.

1. For each plant/unit,

a. Please discuss maintenance and surveillance activities which resulted in a breach of the containment spray piping system between the CS007A/B valves and the spray nozzles since the last performance of the TS SR 3.6.6.8 test. Work activities near the ring headers which could have introduced foreign material into the nozzles (such as painting) should also be included in your evaluation.

b. Please describe any foreign material exclusion program requirements implemented at the time of the activity. This should include required QA cleanliness inspections results.

c. Describe what assurance you have that no foreign material could have entered each plant/units containment spray system during each of the occasions. In particular, please explain why any plant-wide concerns with the implementation of the FME program would not have affected the confidence that the containment spray system is free from debris.

2. Please explain the steps you will take to ensure that after revising TS SR 3.6.6.8, as proposed, that the FME program at each site will be maintained at the level necessary to provide assurance that the containment spray nozzles will remain free from blockage during future maintenance activities or testing. In your explanation, please discuss your evaluation of the current program as implemented, including any actions you plan to take to enhance or strengthen the program.
