Pre-Submittal Teleconference Millstone Power Station Unit 2 License Amendment Request for Spent Fuel Pool Heat Load Analysis in Response to Confirmatory Order EA-13-188 December 17, 2015 Pg. 2 Agenda Purpose of LAR Scope of LAR Schedule Pg. 3 Purpose of LAR LAR required by Confirmatory Order EA-13-188 (8/26/15) Compliance Item #5: amendment request seeking NRC approval of the spent fuel pool heat load analysis and any associated technical specification changes. This DNC has determined no change to the TS is required Request approval of the SFP heat load analyses, TS Bases Section 3/4.9.3 and FSAR Section 9.5 LAR meets regulatory criteria and will preserve health and safety of the public Pg. 4 Scope of LAR LAR will request NRC review and approval of proposed changes to TS Bases Section 3/4.9.3 to remove spent fuel pool decay heat load Proposed bases change is based on the TS prior to the 2009 Bases change made by DNC under 10 CFR 50.59 Change will remove reference to Spent Fuel Pool Decay Heat Load The change is consistent with 10 CFR 50.36 and previous License Amendments 240 (2/10/2000) and 315 (6/4/2013)

Pg. 5 Scope of LAR (Continued) LAR will request NRC review and approval of proposed changes to FSAR Section 9.5 Proposed changes are based on the FSAR prior to the 2010 change made by DNC under 10 CFR 50.59 Proposed FSAR change reflects revisions to: Spent fuel movement decay time Cooling water temperatures (RBCCW) Spent fuel movement rate Scope of LAR (Continued) LAR will provide a summary of the analysis results supporting fuel movement starting at 100 hours0.00116 days <br />0.0278 hours <br />1.653439e-4 weeks <br />3.805e-5 months <br /> after reactor shutdown at a rate of 6 assemblies per hour. LAR will include the proprietary analyses performed by Holtec International submitted under 10 CFR 2.390 Holtec Report No. HI-971778, Rev. 2 "Heat Load from the Spent Fuel Holtec Report No. HI-2094491, Rev. 0, "Thermal- Hydraulic Analysis of Millstone Unit 2 Spent Fuel Pool with Increased Fuel Transfer Rate and Reduced In- Holtec Report No. HI-981901, Rev. 0 including Addenda A & B, "Spent Fuel Pool Thermal- Pg. 6 Pg. 7 Schedule DNC will submit the LAR by February 15, 2016 Request review of this LAR within one year of submittal To maintain compliance with the Confirmatory Order, Standing Order 14-21 is in place prohibiting fuel movement prior to 150 hours0.00174 days <br />0.0417 hours <br />2.480159e-4 weeks <br />5.7075e-5 months <br /> after shutdown.
