SUBJECT :
Document Control Desk Calvert Cliffs Nuclear Power Plant Unit Nos. I & 2; Docket Nos. 50-317 & 50-318 Nine-Month Response to NRC Generic Letter 2008-01, "Managing Gas Accumul ation in Emergency Core
- Cooling, Decay Heat
- Removal, and Containment Spray Systems" The Nuclear Regulatory Commission (NRC) issued Generic Letter (GL) 2008-01 (Reference a) to request that each licensee evaluate the licensing basis, design, testing, and corrective action programs for the Emergency Core Cooling Systems, Decay Heat Removal system, and Containment Spray system, to ensure that gas accumulation is maintained less than the amount that challenges operab ility of these systems, and that appropriate action is taken when conditions adverse to quality are identified.
Reference (a) requested each licensee to submit a written response in accordance with 10 CFR 50.54(t) within nine months of the date of the GL, consistent with the requested actions and information.
Attachment (l ) to this letter contains our nine-month response to NRC GL 2008-01.
Additionally, the NRC requested that if a licensee cannot meet the requested response date, the licensee "shall provide a response within 3 months of the date of this GL." In the three month response, we were requested to describe the alternate course of action that we proposed to take, including the basis for the acceptability of the proposed alternative course of action. In Reference (b), as revised in Reference (c),
we provided our three-month response to the requested information in NRC GL 2008-01 for Calvert Cliffs Unit 2, describing the alternative course of action we proposed to take.
As documented in Reference (d), the NRC staff reviewed our proposed alternati ve course of action and concluded that for Calvert Cliffs Unit 2, with the exception of clarifications and associated requests discussed in the enclosure to Reference (d), our proposed alternati ve course of action related to our nine-month supplemental (post-outage) response was acceptable.
Reference (d) requested that we submit a three-month supplemental response to revise our proposed alternative course of action. Reference (e) is our three-month supplemental response to NRC GL 2008-01 for both Unit 1 and Unit 2.
