ULNRC-06164 December 15, 2014 Page2 6. NRC Memorandum from J. Holonich to A.J. Mendiola re: Minutes From Aug 19 2014 Meeting on Gas Voids NEI Version, dated October 1, 2014, Accession Number ML14266A168 NRC Generic Letter (GL) 2008-01, "Managing Gas Accumulation in Emergency Core Cooling, Decay Heat Removal, and Containment Spray Systems," dated January 11, 2008 (Reference 1) was issued pursuant to the requirements of 10 CFR Part 50.54(+/-) to request information from licensees regarding how they protect certain safety systems from the accumulation of air, nitrogen or other gases that could cause the systems to become inoperable. The GL requested licensees evaluate their emergency core cooling (ECCS), decay heat removal (RHR), and containment spray (CS) systems in order to determine how their licensing basis, design, testing and corrective actions ensure that gas accumulation is maintained less than the amount that challenges operability of these systems, and that appropriate action is taken when conditions adverse to quality are identified. Specifically, the NRC requested licensees to provide the following information: 1. A description of the results of evaluations that were performed pursuant to the above requested actions. This description should provide sufficient information to demonstrate that the licensee is or will be in compliance with the quality assurance criteria in Sections III, V, XI, XVI, and XVII of Appendix B to 10 CFR Part 50 and with the licensing basis and operating license, as those requirements apply to subject systems; 2. A description of all corrective actions, including plant, programmatic, procedure, and licensing basis modifications that the licensee determined were necessary to assure compliance with these regulations, and 3. A statement regarding which corrective actions were completed, the schedule for completing the remaining corrective actions, and the basis for that schedule. By letter dated April 10, 2008 (Reference 2) Ameren Missouri provided a 3-month response to the GL, indicating that not all of the required plant walkdowns and evaluations would be completed by the October 11, 2008 deadline. Ameren Missouri's April10, 2008letter was subsequently acknowledged by the NRC in a letter to Ameren Missouri dated September 18,2008 (Reference 3). Ameren Missouri's 9-month response for Callaway Plant Unit 1 was provided in Reference 4. As indicated in the 9-month response, Ameren Missouri committed to providing a supplemental response within 90 days of the completion of the Refuel16 outage which concluded on November 7, 2008. Ameren Missouri satisfied that commitment via letter dated February 4, 2009 (Reference 5), which concluded that the ECCS, RHR, and CS systems are capable of performing their specified safety functions and that the systems are in compliance with their licensing basis with respect to the concerns outlined in GL 2008-01. The only remaining corrective action involves the resolution of the definition of"full" in Technical Specification Surveillance Requirements for the subject systems and the corresponding updates to the Final Safety Analysis Report. Ameren Missouri committed in its 9-month response to monitor the industry resolution of this issue and submit a license amendment request, as appropriate, within one ULNRC-06164 December 15, 2014 Page 3 year following NRC approval of the TSTF Traveler or Consolidated Line Item Improvement Process (CLIIP) Notice of Availability (Reference 4 Commitment 2). Notice of Availability for adopting TSTF -523 under the CLIIP was provided in 79 FR 2700 on January 15, 2014, committing Ameren Missouri to resolving the issue by January 15, 2015. However, as recognized in the memorandum dated October 1, 2014 to Licensing Processes Branch Chief Anthony J. Mendiola (Reference 6), the industry does not fully understand the NRC endorsed guidance for implementing TSTF-523 (i.e., RIS 2013-09 and NEI 09-10 Revision 1a-A). Therefore, Ameren Missouri is submitting this supplemental response to GL 2008-01 consistent with the guidance provided in NEI 99-04 to notify the NRC that site management has approved the extension of the commitment to submit a license amendment request within one year of the NRC CLIIP Notice of Availability (Reference 4 Commitment 2). The due date will be extended by one year to January 15, 2016 to allow time for the industry to gain understanding of NRC guidance for implementing TSTF-523. This response is submitted in accordance with 10 CFR 50.4. This letter does not contain new commitments; however, this letter does provide notice of a change to an existing commitment as summarized in Enclosure I. If there are any questions or if additional information is needed, please contact Mr. Scott Maglio at (573) 676-8719 or Mr. Tom Elwood at (573) 676-6479.
