NMP2 SIX MONTH UPDATE (FEBRUARY 2016)

FOR RELIABLE SPENT FUEL POOL INSTRUMENTATION 1 Introduction The Nine Mile Point Unit 2 (NMP2) Overall Integrated Plan (OIP) was submitted to the Nuclear Regulatory Commission (NRG) in February 2013 (Reference 1), documenting the requirements to install reliable spent fuel pool level instrumentation (SFPLI), in response to Reference 2.

Subsequently, a supplement to the OIP for SFPLI was submitted to the NRG in March 2013 (Reference 3). By letter dated June 5, 2013 (Reference 4), the NRG requested that NMP respond to a request for additional information (RAI) regarding the NMP2 OIP for Reliable Spent Fuel Pool Instrumentation. By letter dated July 5, 2013 (Reference 5), NMP2 responded to the June 5, 2013 RAI. By letter dated Aug 27, 2013 (Reference 6), NMP2 provided the first Six Month Update. By letter dated November 15, 2013 (Reference 7), the NRG provided NMP with its Interim Staff Evaluation (ISE) and RAI regarding the OIP for Reliable Spent Fuel Pool Instrumentation. By letter dated February 24, 2014 (Reference 10), NMP2 provided the second Six Month Update. By letter dated August 26, 2014 (Reference 11 ), NMP2 provided the third Six Month Update. By letter dated February 19, 2015 (Reference 12), NMP2 provided the fourth Six Month Update. By letter dated August 28, 2015 (Reference 14), NMP2 provided the fifth Six Month Update. Installation is complete up to the final power supply tie-in, which requires a refueling outage.

By letter dated April 28, 2015 the NRG issued to Nine Mile Point the report for the on-site audit conducted at NMP in November 2014 regarding Mitigating Strategies and Reliable Spent Fuel Instrumentation related to Orders EA-12-049 and EA-12-051, which provided a status of all open audit review items that the NRG staff is evaluating in anticipation of issuance of a combined Safety Evaluation for both the Mitigating Strategies and Spent Fuel Instrumentation orders (Reference 13). The Audit Report contained no open items related to Spent Fuel Instrumentation at NMP.

This enclosure provides an update of milestone accomplishments since submittal of the OI P, including any changes to the compliance method, schedule, or need for relief/relaxation and associated basis (if applicable). NMP2 has completed detailed design for the SFPLI System and completed Site Acceptance Testing.

2 Milestone Accomplishments The following milestones have been completed since the development of the OIP (Reference 1),

and are current as of February 5, 2016.

  • Submitted Overall Integrated Plan 102013
  • Issued Purchase Order for Instrumentation 202013
  • Commenced Engineering and Design 202013
  • Selected Instrumentation and Technology 202013
  • Completed Detailed Design 202014
  • Commenced installation of SFPLI System 402014 3 Milestone Schedule Status Table 1 provides an update to the milestone schedule to support the OIP (References 1 and 3).

It provides the activity status of each item and the expected completion date, noting any change. The dates are planning dates subject to change as design and implementation details are developed. Any changes to the following target completion dates will be reflected in the notification of compliance to the NRG.

This change is related to the method used to determine the Level 2 Water Level and was described in the February 2015 Six Month Update (Reference 12).

No additional changes have been made.

5 Need for Relief/Relaxation and Basis for the Relief/Relaxation NMP2 expects to comply with the Order implementation date and no relief/relaxation is required at this time.

6 Open Items from Overall Integrated Plan and Interim Safety Evaluation Table 2 provides a status of the OIP open items documented in the February 2014 Six Month Update (Reference 10). These open items include previous regulatory commitments made in the July 2013 RAI Response (Reference 5). As noted in the memorandum from C.A. Hunt (NRC) to M.A. Mitchell (NRC), Summary of the November 26, 2013 Public Meeting to Discuss Industry Responses to Staff Interim Evaluations for Spent Fuel Pool Instrumentation (Reference 9), the ISE questions supersede any previous requests for information issued by the staff concerning the spent fuel pool instrumentation.
