Omaha Public Power District's Revised Overall Integrated Plan for Fuel Permanently Removed from the Reactor Vessel to the Spent Fuel Pool in Response to Requirements for Mitigation Strategies for Beyond Design Basis External Events

==References:==
See page 4 By letter dated August 12, 2016 (Reference 1), the Omaha Public Power District (OPPD) requested relaxation of the implementation date for compliance with Order EA-12-049 to August 31, 2017, based on plans to remove all fuel from the reactor pressure vessel (RPV) to the spent fuel pool (SFP) by December 31, 2016. The new Overall Integrated Plan (OIP) for Fuel Permanently Removed from RPV to SFP is enclosed as discussed in Reference 1. As stated in Reference 2, the OIP includes an assessment of the reevaluated flooding hazards applicable to FCS with all fuel in the SFP and the capability to mitigate these re-evaluated flooding hazards.
The following are key aspects of the OIP with all fuel in the SFP:
* The Seismic and Flooding External Hazards have been updated consistent with OPPD's responses to the 50.54(f) letter Reference (6).
* The Storms , Hurricanes, High Winds and Tornadoes External Hazard has been revised to be consistent with the Updated Final Safety Analysis Report (USAR) to reflect the changes made in Amendment 272.
* SFP temperature and boil off calculations use a decay heat level corresponding to 60 days after shutdown for fuel removed from the RPV to the SFP.
* Sequences of Events are provided for two limiting flooding scenarios in addition to the extended loss of alternating current (ac) power (ELAP) Sequence of Events.
* The bases for time constraints have been established.
* Guidance documents have been developed and validated.

Open Items The NRC staffs review of the FCS OIPs , as supplemented , and as augmented in the audit process (Reference 3) , identified the items in Table 1 currently under NRC Staff review that require OPPD input. The following input is provided for each Audit Item.
Cl 3.2.4.2.C As discussed in the enclosed OIP, only the Spent Fuel Pool Instrument (SFPI) is used to monitor conditions in the mitigating strategies. The SFPI includes a stand-alone battery backup and the batteries housed in the battery room are no longer required to implement the mitigating strategies. Therefore, it is recommended this item be closed .
AQ.19 The FLEX safety injection refueling water tank pump is replaced with submersible pumps in the OIP mitigating strategies. Therefore, it is recommended this item be closed.
SE.14 As discussed in the attached OIP, no equipment in the containment is relied upon during an ELAP. Therefore , it is recommended this item be closed.
SE.17 The overall flooding strategy is discussed in the enclosed OIP. No open items are associated with the enclosed OIP.
Milestones The following will be completed by December 31, 2016:
Installation of the SFPI Installation of the standpipe between Rooms 81 and 69 Training and issuance of procedures and guidelines Procurement of the diesel fuel oil transfer pumps FLEX equipment staged in either the safety-related plant structures or in the FLEX Storage Building.

Staffing Assessment OPPD provided the Fort Calhoun Station Phase 2 Staffing Assessment Report in Reference 4 showing that the minimum on-shift staffing necessary to implement the mitigating strategies. In accordance with Reference 5, the required on-shift staffing will be reduced from 13 people to 8 people with the plant in a permanently defueled condition. This reduced on-shift staffing is sufficient to perform the required emergency response functions and implement spent fuel pooling cooling requirements.

Applicable Extreme External Hazard 1
1 The applicable extreme external hazards for Fort Calhoun Station (FCS) with all fuel stored in the Spent Fuel Pool (SFP) are seismic, external flood , high winds, snow, ice, cold temperatures and high temperature as detailed below:
Seismic Hazard Assessment The FCS design basis seismic hazard is described in Reference 1. In response to Omaha Public Power District (OPPD) submittals, the NRC determined (Reference 2) that FCS screens out of conducting a seismic risk evaluation because the Individual Plant Examination for External Events (IPEEE) demonstrates plant seismic capacity to levels higher than the ground motion response spectra (GMRS) in the 1-10 Hertz (Hz) range. NRC concurred OPPD demonstrated that the IPEEE-related screening criteria in the NRC-approved industry guidance was met (Reference 2) The NRC staff determined that OPPD provided the necessary information requested in Enclosure 1, Items ( 1) - (7) of the 50 .54(f) letter (Reference 3) . Further the NRC concluded :
Contingent upon the NRC staff's review and acceptance of OPPD's spent fuel pool evaluation (i.e., Item (9) of the 50.54(1) letter) and the full- scope Individual Plant Examination of External Events (IPEEE) relay chatter review (requested to meet the criteria for using an IPEEE program) to demonstrate that a seismic risk evaluation (Item 8) is not merited for FCS, the Seismic Hazard Evaluation identified in Enclosure 1 of the 50 .54(1) letter will be completed .
The NRC concluded OPPD's implementation of the SFP integrity evaluation (Reference 4) met the SFP Evaluation Guidance for Fort Calhoun and therefore, OPPD responded appropriately to Item 9 in Enclosure 1 of the NRC's 50 .54(1) letter.
By letter dated August 25, 2016 (Reference 5) , OPPD provided formal notification to the U.S.
Nuclear Regulatory Commission (NRC) pursuant to 10 CFR 50.4(b)(8) and 10 CFR 50.82(a)(1)(i) certifying that it plans to permanently cease power operations at FCS on October 24, 2016 . FCS plans to remove all fuel from the reactor pressure vessel (RPV) to the SFP by December 31, 2016. Because Ft. Calhoun will be ceasing operation and based on the seismic hazard discussion in SECY-15-0081 , OPPD is not proceeding with IPEEE relay chatter review. OPPD concludes the FCS site screens in using the design basis seismic hazard.
External Flood Hazard Assessment See Appendix A Storms. Hurricanes. High Winds and Tornadoes The following information is per USAR [Ref. 8, Chapter 2.5]:
The physical design parameters of tornado protection systems are such that designated SSCs are able to maintain their necessary capabilities in the event of a Design Basis Tornado (DBT) . Amendment 272 revised the DBT and associated tornado missiles for Fort Calhoun Station (FCS) to that defined in Regulatory Guide (RG) 1.76, Revision 1.
The spectrum of hypothetical missiles used for the design basis analysis are [Ref. 8, Table 5.8-2 :

site screens out for hurricanes because it is located several hundred miles from the nearest sea coast.
Snow, Ice Storms and Cold The hazard remains the same as assessed , audited and described in References 1, 6, and 7.
Per USAR [Ref. 8, Table 2.5-4], the max1mum snow and 1ce accumulation 1n and around FCS      1 in any 24-hour period was 18.3 inches. The lowest recorded temperature from National Weather Service data in Omaha is -32 &deg;F. Thus the FCS site screens in for snow, ice storms and cold.
Extreme Heat The hazard remains the same as assessed , audited and described in References 1, 6, and 7. The extreme temperature recorded at the site is 114&deg;F, per USAR [Ref. 8, Table 2.5-5]. Thus the FCS site screens in for extreme heat.

Key Site assumptions
* The fuel is permanently removed from the RPV and containment to the SFP
* SFP temperature and boil off calculations are based a decay heat level corresponding to 60 days after shutdown for fuel removed from the RPV to the SFP. To minimize the response time available, conservatively high values were selected for decay heat and conservatively low values were selected for initial pool and tank levels. The only SFP heat losses assumed were from the latent heat of evaporation.
* Initial conditions assumed for events other than beyond design basis flooding are consistent with References 1 and 2 with the following exception
: 1. Because the fuel is removed from the RPV and containment to the SFP there 1
is no secondary cooling.

U.S. Nuclear Regulatory Commission LIC-16-0095 Enclosure 1 Page 6 Fort Calhoun Station Decommissionin Overall Inte rated Im lementation Plan T +24 hr:       Establish Spent Fuel Pool (SFP) cooling by starting SFP makeup. Assuming ELAP initiation 60 days after shutdown, the SFP reaches 200 &deg;F in approximately 15 hours and boiling will start. The water level would reach 12'-
6" above the top of the active fuel in in 76 hours. Additional boil off from SFP will result in SFP level reduction to top of active fuel in approximately 129 hours. Makeup flow rate will be established to maintain SFP level within the desired band . Makeup flow rates of approximately 20 gpm, assuming ELAP initiation 60 days after shutdown , are needed to maintain the SFP level. The strategy ensures that makeup flow, in excess of the boil off rate, is initiated prior to reaching Level 2 (well within 76 hours). Using only the SIRWT as the source for makeup water, there is adequate inventory to maintain the SFP water level above Level 2 for more than 12 days.
T+ 5 days       Establish makeup to Safety Injection Refueling Water Tank (SIRWT) from an alternate source of water (ultimate heat sink- Missouri River). Based on makeup needs to the SFP , using only the SIRWT as the source for makeup water, and using conservative assumptions for available water from the I                 SIRWT, the SIRWT will be depleted in approximately 12 days.

A plant system designation is assigned to FLEX. This establishes responsibilities, maintenance and testing requirements for all components
, associated with FLEX. Unique identification numbers are assigned to all FLEX components included in the system. Equipment associated with these strategies is procured as commercial equipment with design, storage, maintenance, testing, and configuration control as outlined in JLD-ISG-2012-01 , Revision 1, Section 6 and NEI12-06, Revision 2, Section 11 . Installed structures, systems and components pursuant to 10 CFR 50 .63(a) will continue to meet the augmented quality guidelines of Regulatory Guide 1.155, Station Blackout.
Standard industry PMs have been developed to establish maintenance and testing frequencies based on type of equipment using the EPRI guidelines. There are some exceptions to the EPRI guidelines consistent with the length of time available to implement the FLEX strategy for a permanently shutdown plant.
Training Training materials for FLEX have been developed for all station staff involved in implementing FLEX strategies . These programs and controls are implemented in accordance with the Systematic Approach to Training . The first rotation of training is complete and a second rotation will be completed prior to December 31, 2016.

PWR Portable Equipment Phase 2:
Based on a site specific calculation, assuming an ELAP initiation 60 days after shutdown, boiling in the SFP will start in approximately 15 hours and the water level would reach 12'-6" above the top of the active fuel in in 76 hours. Additional boil off from SFP will result in a SFP level reduction to top of active fuel in approximately 129 hours. Makeup flow rate will be established to maintain SFP level between within the desired band . Makeup flow rates of approximately 20 gpm is needed to maintain the SFP level. Using only the SIRWT as the source for makeup water, there is adequate inventory to maintain the SFP water level above Level 2 for more than 12 days.
Details:
Strategies The strategy used to maintain spent fuel pool cooling is illustrated in Figure 1. Water to maintain the level in the SFP is supplied from the SIRWT via one of two submersible pumps.
The water from the pump is routed through a valve station to the SFP. Electrical power is supplied via one of two DG. The DG are located such that this strategy can be implemented for the worst case Sunny Day dam failure and adequate time is available to deploy equipment before flood waters arrive at the site. If conditions exist where a BOB flood could submerge the DG in their normal storage location, one DG is relocated to a higher elevation above the predicted level of a flood due to a hydraulic failure of one of the dams.
I II Procedures and                    The procedure flow chart is shown in Figure 2 and the Guidelines                      . procedures are listed in Table 1.

SFP cooling can continue to be provided indefinitely (The on-site OG fuel will last more than 30 days) using the Phase 2 strategy. Guidance is provided to provide fuel to the OG and to replenish the water in the SIRWT. This would be the case for BOB flooding where it is unlikely internal plant electrical buses could be restored . In the case of BOB flooding, a stand-alone self-powered heat exchanger would need to be installed and operated. Because of the large number of unknowns that would have to be addressed, additional guidance has not been developed for recovery from BOB flooding. For cases where the plant electrical busses can be restored, guidance is provided.                                                                  I Details:
