NRC QUESTIONS ON PREVIOUS ACTIONS WITH CW BLWDWN VAC BRKRS

Description:

Originator: JOHN M KIJOWSKI Supv Contacted: Dave Gustafson Condition

Description:

During NRC debrief on 8/31/05, there was discussion regarding the CW blowdown vacuum breaker, OCW058, leakage that was identified in May 2005 (Reference IR 336401). A previous root cause was performed for vacuum breaker failures that occurred in 2000. The NRC question is: Subsequent to 0CW058 leakage identified in May 2005, were the root cause actions reviewed for adequacy? If so, what was the conclusion?

Immediate actions taken:

Write IR for Engineering follow up to answer the questions.

Recommended Actions:

Assign an action item (ACIT) to Engineering (A8930TT) to document the response to the questions and also that feedback was provided to the NRC.

Due Date: 10/07/05 What activities, processes, or procedures were involved?
