RAI Questions regarding RBS Drywell Bypass Test Interval Extension - With attachment Bill, I have attached RAI questions that were forwarded to me by the staff of the Civil and Engineering Mechanics Section of the Mechanical and Civil Engineering Branch of the Division of Engineering regarding River Bend Station License Amendment Request (LAR 2004-02) dated February 16, 2004, (NRC TAC MC2071) which seeks a one-time extension of the Drywell Bypass Test Interval.

After you and your colleagues have had a chance to evaluate them, we can set up a call to discuss them further if you desire to do so.

Thanks, Mike Webb NRC Project Manager for Rver Bend Station 301-415-1347

REQUEST FOR ADDITIONAL INFORMATION LICENSE AMENDMENT REQUEST LAR-2004-02 ONE-TIME EXTENSION OF DRYWELL BYPASS LEAKAGE TEST INTERVAL RIVER BEND STATION. UNIT 1 TAC NO. MC2071

1. The amendment request states that two drywell bypass leakage tests (DBWTs) have been performed. Provide the results of these tests and describe any remedial actions taken to restore leakage to acceptable limits.

2. Discuss whether significant drywell leakage can be detected during normal operation.

3. The DWBTs and inspections complement each other in ensuring the structural and functional integrity of the drywell and containment. The amendment request does not provide information related to the structural and functional integrity of the drywell.

Describe the inspections (i.e., inservice inspection program or other programs) used to verify the integrity of the drywell boundary, including the drywell head to flange connections and other drywell penetrations. Provide a summary of the acceptance criteria, degradations found during these examinations (including location, size, root cause, etc.), and corrective actions taken.
