Dave:
Our reviewer, Emmett Murphy, has completed his initial review of your 2/24/05 submittal and found that he needs answers/clarification to a number of questions (below). Emmett will not be back in the office until after July. Please work with me to set up a conference call to discuss the following 2 questions:
- 1. How were the indications identified in the lower tubesheet region, including those located above the expansion region, factored into condition monitoring assessment for structural and accident leakage integrity? This description should include a description of the loads considered for the structural assessment (axail load and differential pressure) and the loads considered for the accident leakage assessment. Include the methodology for assessing accident induced leakage.
- 2. Were the indications in the non-expanded portion of tubing in the lower tubesheet identified with the bobbin probe or only with the MRPC? If not identified with the bobbin, should the use of MRPC in this region be expanded during future steam generator inspections?
This e-mail aims solely to prepare you and others for the requested conference call. It does not convey a formal NRC staff position, nor does it formally ask for additional information.
