Draft RAI re. DC Cook's Response to GL 2003-01, Control Room Habitability (TAC MB9794, 5)
Mike, Joe:
We are reviewing your 12/4/03 submittal on this GL, and identified the following need for information:
Generic Letter 2003-01 requested confirmation that your facilitys control room meets the applicable habitability regulatory requirements and that it is designed, constructed, configured, operated, and maintained in accordance with the facilitys design and licensing bases. The Generic Letter further states that emphasis should be placed on confirming that the most limiting unfiltered inleakage into your CRE (and the filtered inleakage if applicable) is no more than the value assumed in your design-basis radiological analyses and hazardous chemical assessments, and requested that you describe how and when you performed the analyses, tests, and measurements for this confirmation. In your 12/4/03 response, you reported the results of your unfiltered inleakage test which you performed using the 1993 edition of ASTM E741 test method, rather than the 2000 edition endorsed by the NRC Regulatory Guide 1.197, Regulatory Position 1.1. In order for the NRC staff to evaluate the acceptability of the results from your alternative test method, the NRC staff requests that you submit the information listed in RG 1.197, Regulatory Position 1.3 that you have not included in your 12/4/03 response. The NRC staff is particularly interested in correlations of results of the 1993 method with a test performed with a methodology described in 2000 edition of the ASTM E471.
This e-mail aims solely to prepare you and others for a proposed conference call. This e-mail does not formally request for additional information, nor does it convey an official NRC staff position. Please call me after 10/2/06 to schedule the proposed conference call.
Thanks.
