Draft RAI on Your Response to Generic Letter 2004-02 (TAC MC4672, MC4673)

Getachew:

By letter dated March 3, 2005, CCNPP provided the 90-day response to the Generic Letter 2004-02 for Calvert Cliffs Nuclear Power Plant, Units 1 and 2. The GL requested that addressees perform an evaluation of the emergency core cooling system (ECCS) and containment spray system (CSS) recirculation functions in light of the information provided in the GL and, if appropriate, take additional actions to ensure system function. Additionally, addressees were requested to submit to the NRC the information specified in the GL. The NRC staff has completed its preliminary review of CCNPP's response and has determined that additional information is needed to complete its review. Following are two draft questions that we plan to send to CCNPP in the form of a formal Request for Additional Information (RAI).

Please call me to discuss the following draft questions, and whether you can respond within 30 days of a formal RAI.

(1) Page 2 of the response stated that the susceptibility of the Unit 1 ECCS and CSS recirculation functions to the adverse effects identified in GL 2004-02 was analyzed using the guidance in Topical Report NEI-04-07. The response did not provide a description of the methodology to be used for the Unit 2 analyses. As requested in GL 2004-02, please provide a description of methodology to be used in the Unit 2 analyses and the planned completion date.

(2) Page 3 of the response requested an extension of the completion date for the Unit 1 corrective action to May 31, 2008. Paragraph 2(b) of the Required Information section of GL 2004-02 states that if all corrective actions will not be completed by December 31, 2007, licensees are to describe how the regulatory requirements discussed in the Applicable Regulatory Requirements section of the GL will be met until the corrective actions are completed. While the NRC staff realizes that information is not required to be provided until September 1, 2005, the NRC staff will not be able to act on CCNPP's request for an extension until that information is provided.

This e-mail aims solely to prepare you and others for the requested phone call. It does not formally convey an NRC staff position, nor does it formally request for additional information. Thank you for your help.
