Burke) to USNRC (Document Control Desk), "Certification of Permanent Removal of Fuel from the Reactor Vessel," dated November 13, 2016 (LIC-16-0074) (ML16319A254) Pursuant to 10 CFR 50.12, Omaha Public Power District (OPPD) requests exemptions from portions of 10 CFR 50.47(b), 10 CFR 50.47(c)(2), and 10 CFR Part 50, Appendix E for the Fort Calhoun Station, Unit 1 (FCS). The requested exemptions would allow FCS to reduce emergency planning requirements consistent with the permanently defueled condition of the station.

On June 24, 2016, OPPD certified that FCS would permanently cease power operations no later

than December 31, 2016, in accordance with 10 CFR 50.82(a)(1)(i) (Reference 1). On August 25, 2016, OPPD certified that FCS would permanently cease power operations in accordance with 10 CFR 50.82(a)(1)(i) on October 24, 2016 (Reference 2). On November 13, 2016 (Reference 3), pursuant to 10 CFR 50.82(a)(1)(ii), OPPD certified that the fuel had been permanently removed from the reactor vessel and placed in the spent fuel pool.

Therefore , pursuant to 10 CFR 50.82(a)(2), the 10 CFR Part 50 license fo r FCS no longer author izes operation of the reactor or emplacement or reten t ion of fuel in the reactor vessel.

U.S. Nuclear Regulatory Commission LIC-16-0109 Page 2 ATTACHMENT 3 CONTAINS INFORMATION BEING WITHHELD FROM PUBLIC DISCLOSURE PER 10 CFR 2.390. UPON SEPARATION, THIS LETTER IS DECONTROLLED The requested exemptions are permissible under 10 CFR 50.12 because they are authorized by law, will not present an undue risk to the public health and safety, are consistent with the common defense and security, and present special circumstances.

More specifically, application of the portions of the regulations from which exemptions are sought is not necessary to ensure adequate emergency response capability for FCS and to achieve the underlying purpose of the rules. Furthermore, continued application of these portions of the regulations from which exemptions are sought would result in an undue hardship or other costs to OPPD and the FCS Decommissioning Trust Fund by requiring continued implementation of unnecessary emergency response capabilities. Finally, granting the requested exemptions would result in benefit to the public health and safety and would not result in a decrease in safety, because they would enhance the ability of the emergency response organization to respond to credible scenarios. The exemption requests are contained in Attachment 1 to this letter. OPPD has performed an analyses which show that 530 days (1 year, 165 days) after permanent cessation of power operations, the spent fuel stored in the spent fuel pool will have decayed to the extent that the requested exemptions may be implemented at FCS without any additional compensatory actions. Following the FCS shutdown, which occurred on October 24, 2016, 530 days after permanent cessation of power operations will occur on April 7, 2018. This analysis is included in

is a nonproprietary version of Attachment 3 suitable for public disclosure.

FCS also plans to submit a Permanently Defueled Emergency Plan and a Permanently Defueled Emergency Action Level scheme, for NRC review and approval pursuant to 10 CFR 50.54(q)(4) and 10 CFR Part 50, Appendix E, Section IV.B.2.

In support of this exemption and the associated license amendment for the Permanently Defueled Emergency Plan, numerous discussions, both electronic and in person, have been held with the cognizant state (Nebraska and Iowa) and local response organizations. On October 13, 2016, FCS facilitated a presentation and discussion that included a line by line review of NSIR/DPR-ISG-02, Emergency Planning Exemption Requests for Decommissioning Nuclear Power Plants, which is the basis for the exemptions. Participants at this meeting include the States of Iowa and Nebraska, Washington and Douglas counties from Nebraska, and Regional leadership from the Federal Emergency Management Agency. Follow up conversations, via phone and email, have been made to address questions from that meeting.

On December 8, 2016, FCS held the scheduled quarterly meeting with the States of Iowa and Nebraska, Douglas and Washington counties of Nebraska, Pottawattamie and Harrison Counties from Iowa, and Regional FEMA representatives. This meeting facilitated discussions on the process and plan changes that would be implemented at FCS as part of the Permanently Defueled

Emergency Plan.

Page 2 Pursuant to 10 CFR 50.12 "Specific exemptions," Omaha Public Power District (OPPD) requests the following regulatory exemptions for the Fort Calhoun Station (FCS):

Certain standards in 10 CFR 50.47(b) regarding onsite and offsite emergency response plans for nuclear power reactors; Certain requirements of 10 CFR 50.47(c)(2) to establish Plume Exposure and Ingestion Pathway Emergency Planning Zones (EPZs) for nuclear power plants; and Certain requirements of 10 CFR Part 50, Appendix E, which establishes the elements that make up the content of emergency plans.

The requested exemptions would allow OPPD to revise the scope of the FCS Emergency Plan to reflect the permanently shutdown and defueled condition of the station. The current 10 CFR Part 50 regulatory requirements for emergency planning (developed for operating reactors) ensured protection of the health and safety of the public while FCS was licensed to operate. However, with the station permanently shut down, defueled, and in a state of decommissioning, some of these requirements exceed what is necessary to protect the health and safety of the public.

The requested exemptions and justification for each are based on, and consistent with, Interim Staff Guidance (ISG) NSIR/DPR-ISG-02, Emergency Planning Exemption Requests for Decommissioning Nuclear Power Plants, issued May 11, 2015 (Reference 1).

FCS is located midway between Fort Calhoun and Blair, Nebraska, on the west bank of the Missouri River. The site consists of approximately 660.46 acres with an additional exclusion area of 582.18 acres on the northeast bank of the river directly opposite the plant buildings. FCS includes the Independent Spent Fuel Storage Installation (ISFSI), located within the protected area, approximately 200 meters north-northwest of the Containment Building. The distance from the reactor containment to the nearest site boundary is approximately 910 meters; and the distance to the nearest residence is beyond the site boundary. Except for the city of Blair and the villages of Fort Calhoun and Kennard, the area within a ten-mile radius is predominantly rural. The land use within the ten-mile radius is primarily devoted to general farming. There are no private businesses or public recreational facilities on the plant property.

Chapter 14 of the FCS Final Safety Analysis Report as Updated (USAR) describes the accident scenarios that are applicable to FCS. Many of the accident scenarios postulated in the USAR for operating power reactors involve failures or malfunctions of systems, which could affect the fuel in the reactor vessel, which in the most severe postulated accidents, would involve the release of large quantities of fission products. With the termination of reactor operations and the permanent removal of fuel from the reactor vessel, such accidents are no longer possible. Therefore, the postulated accidents involving failure or malfunction of the reactor, reactor cooling system, steam system, or turbine generator are no longer applicable.

LIC-16-0109

Page 3 On June 24, 2016 (Reference 2), OPPD certified that FCS would permanently cease power operations. On August 25, 2016 (Reference 3), pursuant to 10 CFR 50.82(a)(1)(i) and 10 CFR 50.4(b)(8), OPPD certified that FCS would permanently cease power operations on

October 24, 2016. On November 13, 2016 (Reference 4), pursuant to 10 CFR 50.82(a)(1)(ii), OPPD certified that the fuel has been permanently removed from the reactor vessel and placed in the spent fuel pool (SFP). Upon docketing of the certifications for permanent cessation of power operations (10 CFR 50.82(a)(1)(i)) and permanent removal of fuel from the reactor vessel (10 CFR 50.82(a)(1)(ii)), pursuant to 10 CFR 50.82(a)(2), the 10 CFR Part 50 license for FCS no longer authorizes operation of the reactor or emplacement or retention of fuel into the reactor vessel. Within two years following permanent cessation of power operations, FCS will submit a Post-Shutdown Decommissioning Activities Report (PSDAR), identifying the method FCS has selected for decommissioning. With the reactor permanently defueled, the reactor vessel assembly and supporting structures and systems will no longer be in operation and will have no function related to the safe storage and management of irradiated fuel in the SFP. A SFP cooling and clean-up system is provided to remove decay heat from spent fuel stored in the SFP and to maintain a specified water temperature, purity, and clarity. The irradiated fuel will be stored in the SFP and/or the ISFSI until it is removed by the Department of Energy (DOE). In order to allow a reduction in emergency planning requirements commensurate with the hazards associated with FCS's permanently shut down and defueled condition, exemptions from portions of 10 CFR 50.47(b); 50.47(c)(2); and 10 CFR Part 50, Appendix E, are needed. OPPD has performed an analysis indicating that 530 days (1 year, 165 days) after permanent cessation of power operations, the spent fuel stored in SFP will have decayed to the extent that the requested exemptions can be implemented at FCS without any compensatory actions. This analysis is included in Attachment 2. Considering the shutdown date of October 24, 2016, 530 days after permanent cessation of power operations will occur on April 7, 2018. OPPD will submit a Permanently Defueled Emergency Plan, including a Permanently Defueled Emergency Action Level scheme, for NRC review and approval pursuant to 10 CFR 50.54(q)(4) and 10 CFR 50, Appendix E, Section IV.B.2. The proposed emergency plan will be based on the exemptions requested herein.

Based on the analyses detailed in Section 4.0, below, OPPD has concluded that the portions of 10 CFR 50.47(b); 10 CFR 50.47(c)(2); and 10 CFR Part 50, Appendix E identified in Tables 1 and 2 below will not be necessary to protect the health and safety of the public when FCS is in the permanently defueled condition and would be unduly burdensome. Approval of the exemptions requested in Tables 1 and 2 would not present an undue risk to the public or prevent an appropriate response in the event of an emergency at FCS. LIC-16-0109

Page 4 OPPD requests exemptions from portions of 10 CFR 50.47(b) and (c)(2) and 10 CFR Part 50, Appendix E to the extent that these regulations apply to specific provisions of onsite and offsite emergency planning that will no longer be applicable to FCS when the certifications required by 10 CFR 50.82(a)(1)(i) and (ii) have been submitted and sufficient decay of the spent fuel has occurr ed. The specific portions of 10 CFR 50.47 and 10 CFR Part 50, Appendix E from which exemptions are being requested are identified using strikethrough text in Table 1 (Exemptions Requested from 10 CFR 50.47(b) and (c)(2)) and Table 2 (Exemptions Requested from 10 CFR Part 50, Appendix E), below. The portions of regulation that are not identified using strikethrough text (i.e., those po rtions for which exemption is not being requested), will remain applicable to FCS. Details related to specific exemption requests are prov ided in the Basis for Exemption column in each table.

1 10 CFR 50.47(b): The onsite and, except as provided in paragraph (d) of this section, offsite emergency response plans for nuclear power reactors must meet the following standards: In the Statement of Considerations for the Final Rule for Emergency Planning requirements for Independent Spent Fuel Storage Installations (ISFSIs) and for monitored retrievable storage (MRS) facilities (60 FR 32430; June 22, 1995) (Reference 5), the Commission responded to comments concerning offsite emergency planning for ISFSIs or an MRS and concluded that, "the offsite consequences of potential accidents at an ISFSI or a MRS [monitored retrievable storage installation] would not warrant establishing Emergency Planning Zones." In a nuclear power reactor's permanently defueled state, the accident risks are more similar to an ISFSI or MRS than an operating nuclear power plant. The draft proposed rulemaking in SECY-00-0145 (Reference 6) suggested that after at least one year of spent fuel decay time, the decommissioning licensee would be able to reduce its emergency planning program to one similar to that required for an MRS under 10 CFR 72.32(b) and additional emergency planning reductions would occur when: (1) approximately five years of spent fuel decay LIC-16-0109

Page 5 time has elapsed; or (2) a licensee has demonstrated that the decay heat level of spent fuel in the pool is low enough that the fuel would not be susceptible to a zirconium fire for all spent fuel configurations. Because of the slow rate of the event scenarios in the postulated accident and postulated beyond design basis events analyses and because the duties of the on-shift personnel at a decommissioning reactor facility are not as complicated and diverse as those for an operating reactor, significant time is available to complete actions necessary to mitigate an emergency without impeding timely performance of emergency plan functions. Exemptions from offsite emergency planning requirements have been approved when the specific site analyses show that at least 10 hours is available from a partial drain down event where cooling of the spent fuel is not effective until the hottest fuel assembly reaches 900 degrees Celsius (°C). Because 10 hours allows sufficient time to initiate mitigative actions to prevent a zirconium fire in the SFP or to initiate offsite protective actions in accordance with a comprehensive approach to emergency planning, offsite emergency plans are not necessary for these permanently defueled nuclear power plant licensees. The OPPD analysis has demonstrated that within 10 days after permanent cessation of power operations, the radiological

consequences of the pos tulated accident will not exceed the limits of the U.S. Environmental Protection Agency's (EPA) Protective Action Guides (PAGs) at the Exclusion Area Boundary (EAB). FCS has performed an analysis indicating that after the spent fuel has decayed for 530 days (1 year, 165 days), for beyond design LIC-16-0109

Page 6 basis events where the SFP is partially drained, and air cooling is not possible, 10 hours is available to take mitigative actions or, if needed, implement offsite protective actions using a comprehensive approach to emergency planning from the time spent fuel cooling is lost until the hottest fuel assembly reaches a temperature of 900°C. FCS maintains procedures and strategies for the movement of any necessary portable equipment that will be relied upon for mitigating the loss of SFP water. These mitigative strategies are maintained in accordance with License Condition 3.G of the FCS Renewed Facility Operating License. These diverse strategies provide defense-in-depth and ample time to provide makeup water or spray to the SFP prior to the onset of zirconium cladding ignition when considering

very low probability bey ond design basis events affecting the SFP. 2 10 CFR 50.47(b)(1): Primary responsibilities for emergency response by the nuclear facility licensee and by State and local organizations within the Emergency Planning Zones have been assigned, the emerge ncy responsibilities of the various supporting organizations have been specifically established, and each principal response organization has staff to respond and to augment its initial response on a continuous basis. See the basis for 10 CFR 50.47(b). 3 10 CFR 50.47(b)(2): On-shift facility licensee re sponsibilities for emergency response are unambiguously defined, adequate staffing to provide initial facility accident response in key functional areas is maintained at all times, timely augmentation of response capabilities is available and the No exemption is requested. LIC-16-0109

Page 7 interfaces among various onsite response activities and offsite support and response activities are specified. 4 10 CFR 50.47(b)(3): Arrangements for requesting and effectively using assistance resources have been made, arrangements to accommodate State and local staff at the licensee's Emergency Operations Facility have been made, and other organizations capable of augmenting the planned response have been identified. Discontinuing offsite emergency planning activities and reducing the scope of onsite emergency planning is acceptable given the significantly reduced offsite consequences when FCS is in the permanently defueled condition. The FCS emergency plan will continue to maintain arrangements for requesting and using assistance resources from offsite support organizations. Decommissioning power reactors present a low likelihood of any credible accident resulting in radiological releases requiring offsite protective measures because of the permanently shut down and defueled status of the reactor. An emergency operations facility (EOF) is not required. The control room or another location can provide for the communication and coordination with offsite organizations for the level of support required. Also see the basis for 10 CFR 50.47(b). 5 10 CFR 50.47(b)(4): A standard emergency classification and action level scheme, the bases of which include facility system and effluent parameters, is in use by the nuclear facility licensee, and State and local response plans call for reliance on information provided by facility licensees for determinations of minimum initial offsite response measures. FCS will adopt the Permanently Defueled Emergency Action Levels (EALs) consistent with those detailed in Appendix C of Nuclear Energy Institute (NEI) 99-01, "Development of EALs for Non-Passive Reactors," Revision 6 (Reference 7), endorsed by the NRC in a letter dated March 28, 2013 (Reference 8). FCS analysis shows that after the spent fuel has decayed for 530 days (1 year, 165 days), for beyond design basis events where the SFP is partially drained, and air cooling is not possible, 10 hours is available to take mitigative or, if needed, offsite protective actions using a comprehensive LIC-16-0109

Page 8 approach to emergency planning from the time spent fuel cooling is lost until the hottest fuel assembly reaches a temperature of 900°C. No offsite protective actions are anticipated to be necessary. Therefore, classification above the Alert level will no longer be required. Also see the basis for 10 CFR 50.47(b). 6 10 CFR 50.47(b)(5): Procedures have been established for notification, by the licensee, of State and local response organizations and for notification of emergency personnel by all organizations; the content of initial and followup messages to response organizations and the public has been established; and means to provide early notification and clear instruction to the populace within the plume exposure pathway Emergency Planning Zone have been established. Per SECY-00-0145 (Reference 6), after approximately 1 year of spent fuel decay time (and as supported by the SFP analysis), the NRC staff believes an exception to the offsite EPA PAG standard is justified for a zirconium fire scenario considering the low likelihood of this event together with time available to take mitigative or protective actions between the initiating event and before the onset of a postulated fire. SECY-13-0112, "Consequence Study of a Beyond-Design-Basis Earthquake Affecting the Spent Fuel Pool for a U.S. Mark I Boiling Water Reactor," (Reference 9) provides that depending on the size of the pool liner leak, releases could start anywhere from eight hours to several days after the leak starts, assuming that mitigation measures are unsuccessful. If 10 CFR 50.54(hh)(2)-type mitigation measures are successful, releases could only occur during the first several days after the fuel was removed from the reactor. As previously indicated, an FCS analysis shows that after the spent fuel has decayed for 530 days (1 year, 165 days), for beyond design basis events where the SFP is partially drained, and air cooling is not possible, 10 hours is available to take mitigative or, if needed, offsite protective actions using a comprehensive approach to emergency planning from the time spent fuel cooling is lost until the hottest fuel assembly reaches a LIC-16-0109

Page 9 temperature of 900°C.Therefore, offsite emergency plans are not necessary for permanently defueled nuclear power plants. Also see the basis for 10 CFR 50.47(b). 7 10 CFR 50.47(b)(6): Provisions exist for prompt communications among principal response organizations to emergency personnel and to the public. See the basis for 10 CFR 50.47(b). 8 10 CFR 50.47(b)(7): Information is made available to the public on a periodic basis on how they will be notified and what their initial actions should be in an emergency (e.g., listening to a local broadcast station and remaining indoors), [T]he principal points of contact with the news media for dissemination of information during an emergency (including the physical location or locations) are established in advance, and procedures for coordinated dissemination of information to the public are established. See the basis for 10 CFR 50.47(b). 9 10 CFR 50.47(b)(8): Adequate emergency facilities and equipment to support the emergency response are provided and maintained. No exemption is requested. 10 10 CFR 50.47(b)(9): Adequate methods, systems, and equipment for assessing and monitoring actual or potential offsite consequences of a radiological emergency condition are in use. See the basis for 10 CFR 50.47(b). LIC-16-0109

Page 10 11 10 CFR 50.47(b)(10): A range of protective actions has been developed for the plume exposure pathway EPZ for emergency workers and the public. In developing this range of actions, consideration has been given to evacuation, sheltering, and, as a supplement to these, the prophylactic use of potassium iodide (KI), as appropriate. Evacuation time estimates have been developed by applicants and licensees. Licensees shall update the evacuation time estimates on a periodic basis. Guidelines for the choice of protective actions during an emergency, consistent with Federal guidance, are developed and in place, and protective actions for the ingestion exposure pathway EPZ appropriate to the locale have been developed. In the unlikely event of a SFP accident, the iodine isotopes which contribute to an offsite dose from an operating reactor accident are not present, so potassium iodide (KI) distribution offsite would no longer serve as an effective or necessary supplemental protective action. Protective actions will be maintained for em ergency workers and any offsite emergency responders who would respond to the site. The Commission responded to comments in its Statement of Considerations for the Final Rule for Emergency Planning requirements for ISFSIs and MRS facilities (60 FR 32435), and concluded that, "the offsite consequences of potential accidents at an ISFSI or a MRS would not warrant establishing Emergency Planning Zones." Additionally, in the Statement of Considerations for the Final Rule for Emergency Planning requirements for ISFSIs and for MRS facilities (60 FR 32430) (Reference 5), the Commission responded to comments concerning site-specific emergency planning that includes evacuation of surrounding population for an ISFSI not at a reactor site, and concluded that, "The Commission does not agree that as a general matter emergency plans for an ISFSI must include evacuation planning." Because the NRC concludes that evacuation planning is not needed for a decommissioning reactor site that meets the criteria for an exemption from offsite EP requirements as discussed in the exemption from 10 CFR 50.47(b), evacuation time estimates are also not needed. LIC-16-0109

Page 11 Also see the basis for 10 CFR 50.47(b) detailing the low likelihood of any credible accident resulting in radiological releases requiring offsite protective measures and the basis for Section IV.1 exemptions for a discussion on the similarity between a permanently defueled reactor and a non-power reactor. 12 10 CFR 50.47(b)(11): Means for controlling radiological exposures, in an emergency, are established for emergency workers. The means for controlling radiological exposures shall include exposure guidelines consistent with EPA Emergency Worker and Lifesaving Activity Protective Action Guides. No exemption is requested. 13 10 CFR 50.47(b)(12): Arrangements are made for medical services for contaminated injured individuals. No exemption is requested. 14 10 CFR 50.47(b)(13): General plans for recovery and reentry are developed. No exemption is requested. 15 10 CFR 50.47(b)(14): Periodic exercises are (will be) conducted to evaluate major portions of emergency response capabilities, periodic drills are (will be) conducted to develop and maintain key skills, and deficiencies identified as a result of exercises or drills are (will be) corrected. No exemption is requested. 16 10 CFR 50.47(b)(15): Radiological emergency response training is provided to those who may be called on to assist in an emergency. No exemption is requested. LIC-16-0109

Page 12 17 10 CFR 50.47(b)(16): Responsibilities for plan development and review and for distribution of emergency plans are established, and planners are properly trained. No exemption is requested. 18 10 CFR 50.47(c)(2): Generally, the plume exposure pathway EPZ for nuclear power plants shall consist of an area about 10 miles (16 km) in radius and the ingestion pathway EPZ shall consist of an area about 50 miles (80 km) in radius. The exact size and configuration of the EPZs surrounding a particular nuclear power reactor shall be determined in relation to local emergency response needs and capabilities as they are affected by such conditions as demography, topography, land characteristics, access routes, and jurisdictional boundaries. The size of the EPZs also may be determined on a case-by-case basis for gas cooled nuclear reactors and for reactors with an authorized power level less than 250 MW thermal. The plans for the ingestion pathway shall focus on such actions as are appropriate to protect the food ingestion pathway. FCS has developed an analysis indicating that 530 days (1 year, 165 days) after permanent cessation of power operations, no credible accident at FCS will result in radiological releases requiring offsite protective actions. The analysis of the potential radiological impact of the postulated accident for FCS in a permanently defueled condition indicates that any releases beyond the site boundary are limited to small fractions of the EPA PAG exposure levels. According to the EPA's "Protective Action Guides and Planning Guidance for Radiological Incidents, Draft for Interim Use and Public Comment," dated March 2013 (PAG Manual), "EPZs are not necessary at those facilities where it is not possible for PAGs to be exceeded off-site." (Reference 10). Also see the basis for 10 CFR 50.47(b). LIC-16-0109

Page 13 19 10 CFR 50 Appendix E III. The Final Safety Analysis Report; Site Safety Analysis Report The final safety analysis report or the site safety analysis report for an early site permit that includes complete and integrated emergency plans under § 52.17(b)(2)(ii) of this chapter shall contain the plans for coping with emergencies. The plans shall be an expression of the overall concept of operation; they shall describe the essential elements of advance planning that have been considered and the provisions that have been made to cope with emergency situations. The plans shall incorporate information about the emergency response roles of supporting organizations and offsite agencies. That information shall be sufficient to provide assurance of coordination among the supporting groups and with the licensee. The site safety analysis report for an early site permit which proposes major features must address the relevant provisions of 10 CFR 50.47 and 10 CFR part 50, appendix E, within the scope of emergency preparedness matters addressed in the major features. The plans submitted must include a description of the elements set out in Section IV for the emergency planning zones (EPZs) to an extent sufficient to demonstrate that the plans provide reasonable assurance that adequate protective measures can and will be taken in the event of an emergency. No exemption is requested. LIC-16-0109

Page 14 20 10 CFR 50 Appendix E IV. Content of Emergency Plans 1. The applicant's emergency plans shall contain, but not necessarily be limited to, information needed to demonstrate compliance with the elements set forth below, , organization for coping with radiological emergencies, assessment actions, activation of emergency organization, notification procedures, emergency facilities and equipment, training, maintaining emergency preparedness, and recovery, and onsite protective actions during hostile action. In addition, the emergency response plans submitted by an applicant for a nuclear power reactor operating license under this part, or for an early site permit (as applicable) or combined license under 10 CFR part 52, shall contain information needed to demonstrate compliance with the standards described in § 50.47(b), and they will be evaluated against those standards. Following docketing of the "Certification of Permanent Removal of Fuel from the Reactor Vessel," in accordance with 10 CFR 50.82(a)(1)(i) and (ii), FCS became a permanently shut down facility with spent fuel stored in the SFP. In the EP Final Rule (76 FR 72596, Nov. 23, 2011) (Reference 11), the NRC defined "hostile action" as, in part, an act directed toward a nuclear power plant or its personnel. This definition is based on the definition of "hostile action" provided in NRC Bulletin 2005-02. NRC Bulletin 2005-02 was not applicable to nuclear power reactors that have permanently ceased operations and have certified that fuel has been removed from the reactor vessel. The NRC excluded non-power reactors (NPRs) from the definition of "hostile action" at that time because an NPR is not a nuclear power plant and a regulatory basis had not been developed to support the inclusion of NPR in that definition. Similarly, a decommissioning power reactor or ISFSI is not a "nuclear reactor" as defined in the NRC's regulations. The following similarities between FCS and NPRs show that the FCS facility should be treated in a similar fashion as an NPR. Similar to NPRs, FCS will pose lower radiological risks to the public from accidents than do power reactors becaus e: (1) FCS will be a permanently shut down facility (with fuel stored in the SFP and ISFSI) and will no longer generate fission products; 2) Fuel stored in the FCS SFP will have lower decay heat resulting in lower risk of fission product release in the event of a beyond design basis boil off or drain down event; and 3) no credible accident at FCS will result in radiological releases requiring offsite protective actions.

Page 15 21 IV.2 This nuclear power reactor license applicant shall also provide an analysis of the time required to evacuate various sectors and distances within the plume exposure pathway EPZ for transient and permanent populations, using the most recent U.S. Census Bureau data as of the date the applicant submits its application to the NRC. See the basis for 10 CFR 50.47(b)(10). 22 IV.3 Nuclear power reactor licensees shall use NRC approved evacuation time estimates (ETEs) and updates to the ETEs in the formulation of protective action recommendations and shall provide the ETEs and ETE updates to State and local governmental authorities for use in developing offsite protective action strategies. See the basis for 10 CFR 50.47(b)(10). 23 IV.4 Within 365 days of the late r of the date of the availability of the most recent decennial census data from the U.S. Census Bureau or December 23, 2011, nuclear power reactor licensees shall develop an ETE analysis using this decennial data and submit it under § 50.4 to the NRC. These licensees shall submit this ETE analysis to the NRC at least 180 days before using it to form protective action recommendations and providing it to State and local governmental authorities for use in developing offsite protective action strategies. See the basis for 10 CFR 50.47(b)(10). 24 IV.5 During the years between decennial censuses, nuclear power reactor licensees shall estimate EPZ permanent resident population changes once a year, but no later than 365 days from the date of the previous estimate, using the See the basis for 10 CFR 50.47(b)(10). LIC-16-0109

Page 16 most recent U.S. Census Bureau annual resident population estimate and State/local government population data, if available. These licensees shall maintain these estimates so that they are available for NRC inspection during the period between decennial censuses and shall submit these estimates to the NRC with any updated ETE analysis. 25 IV.6 If at any time during the decennial period, the EPZ permanent resident population increases such that it causes the longest ETE value for the 2-mile zone or 5-mile zone, including all affected Emergency Response Planning Areas, or for the entire 10-mile EPZ to increase by 25 percent or 30 minutes, whichever is less, from the nuclear power reactor licensee's currently NRC approved or updated ETE, the licensee shall update the ETE analysis to reflect the impact of that population increase. The licensee shall submit the updated ETE analysis to the NRC under § 50.4 no later than 365 days after the licensee's determination that the criteria for updating the ETE have been met and at least 180 days before using it to form protective action recommendations and providing it to State and local governmental authorities for use in developing offsite protective action strategies. See the basis for 10 CFR 50.47(b)(10). 26 IV.7 After an applicant for a combined license under part 52 of this chapter receives its license, the licensee shall conduct at least one review of any changes in the population of its EPZ at least 365 days prior to its scheduled fuel load. The licensee shall estimate EPZ permanent resident population changes No exemption is requested. FCS is not an applicant for a combined license. Therefore, this regulation is not applicable to FCS and an exemption is not necessary. LIC-16-0109

Page 17 using the most recent U.S. Census Bureau annual resident population estimate and State/local government population data, if available. If the EPZ permanent resident population increases such that it causes the longest ETE value for the 2-mile zone or 5-mile zone, including all affected Emergency Response Planning Areas, or for the entire 10-mile EPZ, to increase by 25 percent or 30 minutes, whichever is less, from the licensee's currently approved ETE, the licensee shall update the ETE analysis to reflect the impact of that population increase. The licensee shall submit the updated ETE analysis to the NRC for review under § 50.4 of this chapter no later than 365 days before the licensee's scheduled fuel load. 27 A. Organization The organization for coping with radiological emergencies shall be described, including definition of authorities, responsibilities, and duties of individuals assigned to the licensee's emergency organization and the means for notification of such individuals in the event of an emergency. Specifically, the following shall be included: No exemption is requested. 28 A.1. A description of the normal plant operating organization. Following docketing of the certifications required by 10 CFR 50.82(a)(1)(i) and (ii), FCS will not be a facility that can be operated to generate electrical power. Therefore, FCS will not have a "plant operating organization." Rather, the station will be maintained by a defueled on-shift staff. LIC-16-0109

Page 18 29 A.2. A description of the onsite emergency response organization (ERO) with a detailed discussion of: a. Authorities, responsibilities, and duties of the individual(s) who will take charge during an emergency; b. Plant staff emergency assignments; c. Authorities, responsibilities, and duties of an onsite emergency coordinator who shall be in charge of the exchange of information with offsite authorities responsible for coordinating and implementing offsite emergency measures. No exemption is requested. 30 A.3. A description, by position and function to be performed, of the licensee's headquarters personnel who will be sent to the plant site to augment the onsite emergency organization. The number of staff at FCS during the decommissioning process will be small but commensurate with the need to safely store spent fuel at the facility in a manner that is protective of public health and safety. FCS will maintain a level of emergency re sponse that does not require response by headquarters personnel. The on-shift and emergency response positions will be defined in the Permanently Defueled Emergency Plan. 31 A.4. Identification, by position and function to be performed, of persons within the licensee organization who will be responsible for making offsite dose projections and a description of how these projections will be made and the results transmitted to State and local authorities, NRC, and other appropriate governmental entities. FCS has developed an analysis indicating that 530 days (1 year, 165 days) after permanent cessation of power operations, no credible accident at FCS will result in radiological releases requiring offsite protective actions. FCS will maintain the capability to determine if a radiological release is occurring and perform dose projections. If a release is occurring, FCS will communicate release and dose projection information to offsite authorities for their consideration. The offsite organizations LIC-16-0109

Page 19 are responsible for deciding what, if any, protective actions should be taken. 32 A.5. Identification, by position and function to be performed, of other employees of the licensee with special qualifications for coping with emergency conditions that may arise. Other persons with special qualifications, such as consultants, who are not employees of the licensee and who may be called upon for assistance for emergencies shall also be identified. The special qualifications of these persons shall be described. As indicated by the FCS adiabatic heatup analysis, the time available to initiate compensatory actions in the event of a loss of SFP cooling or inventory precludes the need to identify and describe the special qualifications of these individuals in the emergency plan. The number of staff at FCS when it is in the permanently defueled state will be small but will be commensurate with the need to operate the facility in a manner that is protective of public health and safety. 33 A.6. A description of the local offsite services to be provided in support of the licensee's emergency organization. No exemption is requested. 34 A.7. By June 23, 2014, identification of, and a description of the assistance expected from, appropriate State, local, and Federal agencies with responsibilities for coping with emergencies, including hostile action at the site. For purposes of this appendix, "hostile action" is defined as an act directed toward a nuclear power plant or its personnel that includes the use of violent force to destroy equipment, take hostages, and/or intimidate the licensee to achieve an end. This includes attack by air, land, or water using guns, explosives, projectiles, vehicles, or other devices used to deliver destructive force. A decommissioning power reactor has a low likelihood of a credible accident resulting in radiological releases requiring offsite protective measures. For this reason and those described in the basis for Section IV.1 of 10 CFR Part 50, Appendix E, a decommissioning power reactor is not a facility that falls within the definition of "hostile action." Similarly, for security, risk insights can be used to determine which targets are important to protect against sabotage. A level of security commensurate with the consequences of a sabotage event is required and is evaluated on a site-specific basis. The severity of the consequences declines as fuel ages, and over time, the underlying LIC-16-0109

Page 20 concern that a sabotage attack could cause offsite radiological consequences is removed. Although, the analysis described above and in the basis for 10 CFR Part 50, Appendix E, Section IV.1 provides a justification for exempting FCS from "hostile action" related requirements, some EP requirements for security-based events will be maintained. The classification of security-based events, notification of offsite authorities, and coordination with offsite agencies under a comprehensive emergency management plan concept will still be required. FCS will maintain appropriate actions for the protection of onsite personnel in a security-based event. The scope of protective actions will be appropriate for the defueled plant status, but will not be the same as actions necessary for an operating power plant. 35 A.8. Identification of the State and/or local officials responsible for planning for, ordering, and controlling appropriate protective actions, including evacuations when necessary. Offsite emergency measures are limited to support provided by local police, fire departments, and ambulance and hospital services as appropriate. An FCS analysis has been developed indicating that 530 days (1 year, 165 days) after permanent cessation of power operations, no credible accident at FCS will result in radiological releases requiring offsite protective actions. Therefore, protective actions such as evacuation should not be required. Also see the basis for 10 CFR 50.47(b)(10). 36 A.9. By December 24, 2012, for nuclear power reactor licensees, a detailed analysis demonstrating that on shift personnel assigned emergency plan implementation functions Responsibilities of the on-shift and emergency response personnel will be detailed in the Permanently Defueled Emergency Plan and

implementing procedures and will be regularly tested through drills LIC-16-0109

Page 21 are not assigned responsibilities that would prevent the timely performance of their assigned functions as specified in the emergency plan. and exercises, audited, and inspected by FCS and the NRC. The duties of the on-shift personnel at a decommissioning reactor facility are not as complicated and diverse as those for an operating power reactor. In the EP Final Rule (Reference 11), the NRC acknowledged that the staffing analysis requirement was not necessary for non-power reactor licensees because staffing at non-power reactors is generally small, which is commensurate with operating the facility in a manner that is protective of the public health and safety. The minimal systems and equipment needed to maintain the spent nuclear fuel in the SFP or in a dry cask storage system in a safe condition requires minimal personnel and is governed by Technical Specifications. Because of the slow rate of the event scenarios in the postulated accident and postulated beyond design basis events analyses and because the duties of the on-shift personnel at a decommissioning reactor facility are not as complicated and diverse as those for an operating reactor, significant time is available to complete actions necessary to mitigate an emergency without impeding timely performance of emergency plan functions. For these reasons, it can be concluded that a decommissioning NPP is exempt from the requirement of 10 CFR Part 50, Appendix E, Section IV.A.9. 37 B. Assessment Actions B.1. The means to be used for determining the magnitude of, and for continually assessing the impact of, the release of radioactive materials shall be described, including emergency FCS will develop EALs consistent with the Permanently Defueled EALs detailed in Appendix C of NEI 99-01, Revision 6 (Reference 7). FCS proposes to continue to review EALs with the State of Nebraska and Washington County on an annual basis. However, based upon the reduced scope of EALs for the permanently LIC-16-0109

Page 22 action levels that are to be used as criteria for determining the need for notification and participation of local and State agencies, the Commission, and other Federal agencies, and the emergency action levels that are to be used for determining when and what type of protective measures should be considered within and outside the site boundary to protect health and safety. The emergency action levels shall be based on in-plant conditions and instrumentation in addition to onsite and offsite monitoring. By June 20, 2012, for nuclear power reactor licensees, these action levels must include hostile action that may adversely affect the nuclear power plant. The initial emergency action levels shall be discussed and agreed on by the applicant or licensee and state and local governmental authorities, and approved by the NRC. Thereafter, emergency action levels shall be reviewed with the State and local governmental authorities on an annual basis. defueled facility, the scope of the annual review of EALs is expected to be limited (i.e., informal mailings, etc.). Also see the basis for Section IV.1 for the justification from the requirements in Appendix E related to "hostile action." 38 B.2. A licensee desiring to change its entire emergency action level scheme shall submit an application for an amendment to its license and receive NRC approval before implementing the change. Licensees shall follow the change process in § 50.54(q) for all other emergency action level changes. No exemption is requested. 39 C. Activation of Emergency Organization C.1. The entire spectrum of emergency conditions that involve the alerting or activating of progressively larger segments of the total emergency organization shall be described. The The Permanently Defueled EALs, developed consistent with Appendix C of NEI 99-01, Revision 6 (Reference 7), will be adopted, as previously described. This scheme eliminates the Site Area Emergency and General Emergency event classifications. LIC-16-0109

Page 23 communication steps to be taken to alert or activate emergency personnel under each class of emergency shall be described. Emergency action levels (based not only on onsite and offsite radiation monitoring information but also on readings from a number of sensors that indicate a potential emergency, such as the pressure in containment and the response of the Emergency Core Cooling System) for notification of offsite agencies shall be described. The existence, but not the details, of a message authentication scheme shall be noted for such agencies. The emergency classes defined shall include: (1) Notification of unusual events, (2) alert, (3) site area emergency, and (4) general emergency. These classes are further discussed in NUREG-0654/FEMA-REP-1. Additionally, the need to base EALs on containment parameters is no longer appropriate. The EAL scheme presented in NEI 99-01, Revision 6 was endorsed by the NRC in a letter dated March 28, 2013 (ML 12346A463). No offsite protective actions are anticipated to be necessary, so classification above the Alert level is no longer required. In the event of an accident at a defueled facility that meets the conditions for relaxation of emergency planning requirements, there will be available time for event mitigation, and if necessary, implementation of offsite protective actions using a comprehensive approach to emergency planning. See the basis for 10 CFR 50.47(b) detailing the low likelihood of any credible accident resulting in radiological releases requiring offsite protective measures. Containment parameters will not provide an indication of the conditions at FCS and emergency core cooling systems will no longer be required. Other indications, such as SFP level or temperature, will be used while there is spent fuel in the SFP. In the Statement of Considerations for the Final Rule for Emergency Planning requirements for ISFSIs and for MRS facilities (60 FR 32430) (Reference 5), the Commission responded to comments concerning a General Emergency at an ISFSI and MRS, and concluded that, "-an essential element of a General Emergency is that a release can be reasonably expected to exceed EPA Protective Action Guidelines exposure levels off site for more than the immediate site area." The probability of a condition reaching the level above an emergency classification of Alert is very low. In the event of an accident at a defueled facility that meets the conditions for relaxation of EP requirements, there will be time to take LIC-16-0109

Page 24 measures to protect the public in accordance with a comprehensive approach to emergency planning. As stated in NUREG-1738, "Technical Study of Spent Fuel Pool Accident Risk at Decommissioning Nuclear Power Plants" (February 2001) (Reference 12) for instances of small SFP leaks or loss of cooling scenarios, these events evolve very slowly and generally leave many days for recovery efforts. Offsite radiation monitoring will be performed as the need arises. Due to the decreased risks associated with defueled plants, offsite radiation monitoring systems are not required. 40 C.2. By June 20, 2012, nuclear power reactor licensees shall establish and maintain the capability to assess, classify, and declare an emergency condition within 15 minutes after the availability of indications to pl ant operators that an emergency action level has been exceeded and shall promptly declare the emergency condition as soon as possible following identification of the appropriate emergency classification level. Licensees shall not construe these criteria as a grace period to attempt to restore plant conditions to avoid declaring an emergency action due to an emergency action level that has been exceeded. Licensees shall not construe these criteria as preventing implementation of response actions deemed by the licensee to be necessary to protect public health and safety provided that any delay in declaration does not deny the State and local authorities the opportunity to implement measures necessary to protect the public health and safety. In the Proposed Rule (74 FR 23254) (Reference 13) to amend certain emergency planning requirements for 10 CFR Part 50, the NRC asked for public comment on whether the NRC should add requirements for non-power reactor licensees to assess, classify, and declare an emergency condition within 15 minutes and promptly declare an emergency condition. The NRC received several comments on these issues. The NRC believed there may be a need for the NRC to be aware of security-related events early on so that an assessment of the likelihood that the event is part of a larger coordinated attack can be made. However, the NRC determined that further analysis and stakeholder interactions are needed prior to changing the requirements for non-power reactor licensees. Therefore, the NRC did not include requirements in the 2011 EP Final Rule (Reference 11) for non-power reactor licensees to assess, classify, and declare an emergency condition within 15 minutes and promptly declare an emergency condition. LIC-16-0109

Page 25 FCS will maintain the capability to assess, classify, and declare an emergency condition within 30 minutes after the availability of indications to operators that an EAL threshold has been reached. Emergency declaration is required to be made as soon as conditions warranting classification are present and recognizable, but within 30 minutes in all cases of conditions being present. In the permanently defueled condition, the rapidly developing scenarios associated with events initiated during reactor power operation are no longer credible. The consequences resulting from the only remaining events (e.g., fuel handling accident) develop over a significantly longer period. As such, the 15 minute requirement to classify and declare an emergency is unnecessarily restrictive. Because of the geographic location of FCS, emergency planning and responsibilities have historically involved coordination with the States of Nebraska and Iowa. Decommissioning-related emergency plan submittals for FCS have been discussed with offsite response organizations since OPPD provided notification that it would permanently cease power operations. These discussions have addressed changes to onsite and offsite emergency preparedness throughout the decommissioning process, including the proposed 30-minute emergency declaration time. Emergency management officials with both states have agreed that this declaration time is appropriate. See the basis for 10 CFR 50.47(b) detailing the low likelihood of any credible accident resulting in radiological releases requiring offsite protective measures and 10 CFR Part 50, Appendix E, Section IV.1 LIC-16-0109

Page 26 for discussion on the similarity between a permanently defueled reactor and a non-power reactor. 41 D. Notification Procedures D.1. Administrative and physical means for notifying local, State, and Federal officials and agencies and agreements reached with these officials and agencies for the prompt notification of the public and for public evacuation or other protective measures, should they become necessary, shall be described. This description shall include identification of the appropriate officials, by title and agency, of the State and local government agencies within the EPZs. See the basis for 10 CFR 50.47(b) and 10 CFR 50.47(b)(10). 42 D.2. Provisions shall be described for yearly dissemination to the public within the plume exposure pathway EPZ of basic emergency planning information, such as the methods and times required for public notification and the protective actions planned if an accident occurs, general information as to the nature and effects of radiation, and a listing of local broadcast stations that will be used for dissemination of information during an emergency. Signs or other measures shall also be used to disseminate to any transient population within the plume exposure pathway EPZ appropriate information that would be helpful if an accident occurs. See the basis for Section IV.D.1. 43 D.3. A licensee shall have the capability to notify responsible State and local governmental agencies within 15 minutes after declaring an emergency. The licensee shall demonstrate that While the capability needs to exist for the notification of offsite government agencies within a specified time period, previous exemptions have allowed for extending the State and local LIC-16-0109

Page 27 the appropriate governmental authorities have the capability to make a public alerting and notification decision promptly on being informed by the licensee of an emergency condition. Prior to initial operation greater than 5 percent of rated thermal power of the first reactor at a site, each nuclear power reactor licensee shall demonstrate that administrative and physical means have been established for alerting and providing prompt instructions to the public within the plume exposure pathway EPZ. The design objective of the prompt public alert and notification system shall be to have the capability to essentially complete the initial alerting and initiate notification of the public within the plum e exposure pathway EPZ within about 15 minutes. The use of this alerting and notification capability will range from immediate alerting and notification of the public (within 15 minutes of the time that State and local officials are notified that a situation exists requiring urgent action) to the more likely events where there is substantial time available for the appropriate governmental authorities to make a judgment whether or not to activate the public alert and notification system. The alerting and notification capability shall additionally include administrative and physical means for a backup method of public alerting and notification capable of being used in the event the primary method of alerting and notification is unavailable during an emergency to alert or notify all or portions of the plume exposure pathway EPZ population. The backup method shall have the capability to alert and notify the public within the plume exposure pathway EPZ, but does not need to meet the 15-minute design government agencies' notification time up to 60 minutes based on the site-specific justification provided. FCS proposes to complete emergency notification to the State of Nebraska within 60 minutes after an emergency declaration or a change in classification. This timeframe is consistent with the 10 CFR 50.72(a)(3) notification to the NRC and is appropriate because in the permanently defueled condition, the rapidly developing scenarios associated with events initiated during reactor power operation are no longer credible and there is no need for State or local response organizations to implement any protective actions. Because of the geographic location of FCS, emergency planning and responsibilities have historically involved coordination with the States of Nebraska and Iowa. Decommissioning-related emergency plan submittals for FCS have been discussed with offsite response organizations since OPPD provided notification that it would permanently cease power operations. These discussions have addressed changes to onsite and offsite emergency preparedness throughout the decommissioning process, including the proposed 60-minute notification to the State of Nebraska. Emergency management officials with both states have agreed that the proposed notification to Nebraska within 60 minutes is appropriate. FCS analyses demonstrate that 530 days (1 year, 165 days) after permanent cessation of power operations, no remaining postulated accidents at FCS will result in radiological releases requiring offsite protective actions, or in the event of beyond design basis accidents, 10 hours is available to take mitigative actions, and if needed, implement offsite protective actions using a comprehensive LIC-16-0109

Page 28 objective for the primary prompt public alert and notification system. When there is a decision to activate the alert and notification system, the appropriate governmental authorities will determine whether to acti vate the entire alert and notification system simultaneously or in a graduated or staged manner. The responsibility for activating such a public alert and notification system shall remain with the appropriate governmental authorities. emergency management plan. Therefore, there is no need to maintain an Alert and Notification System. Also see the basis for 10 CFR 50.47(b) and 10 CFR 50.47(b)(10). 44 D.4. If FEMA has approved a nuclear power reactor site's alert and notification design report, including the backup alert and notification capability, as of December 23, 2011, then the backup alert and notification capability requirements in Section IV.D.3 must be implemented by December 24, 2012. If the alert and notification design report does not include a backup alert and notification capability or needs revision to ensure adequate backup alert and notification capability, then a revision of the alert and notification design report must be submitted to FEMA for review by June 24, 2013, and the FEMA-approved backup alert and notification means must be implemented within 365 days after FEMA approval. However, the total time period to implement a FEMA-approved backup alert and notification means must not exceed June 22, 2015. See the basis for Section IV.D.3 regarding the alert and notification system requirements. 45 E. Emergency Facilities and Equipment Adequate provisions shall be made and described for emergency facilities and equipment, including: No exemption is requested. LIC-16-0109

Page 29 E.1. Equipment at the site for personnel monitoring; 46 E.2. Equipment for determining the magnitude of and for continuously assessing the impact of the release of radioactive materials to the environment; No exemption is requested. 47 E.3. Facilities and supplies at the site for decontamination of onsite individuals; No exemption is requested. 48 E.4. Facilities and medical supplies at the site for appropriate emergency first aid treatment; No exemption is requested. 49 E.5. Arrangements for medical service providers qualified to handle radiological emergencies onsite; No exemption is requested. 50 E.6. Arrangements for transportation of contaminated injured individuals from the site to specifically identified treatment facilities outside the site boundary; No exemption is requested. 51 E.7. Arrangements for treatment of individuals injured in support of licensed activities on the site at treatment facilities outside the site boundary; No exemption is requested. 52 E.8.a(i) A licensee onsite technical support center and an emergency operations facility fr om which effective direction can be given and effective control can be exercised during an emergency; FCS analyses demonstrate that 530 days (1 year, 165 days) after permanent cessation of power operations, no remaining postulated accidents at FCS will result in radiological releases requiring offsite protective actions, or in the event of beyond design basis accidents, 10 hours is available to take mitigative actions, and if needed, implement offsite protective actions using a comprehensive LIC-16-0109

Page 30 emergency management plan. Therefore, there is no need to maintain a TSC or an EOF. Offs ite agency response will not be required at an EOF and onsite actions may be directed from the Control Room or another location, without the requirements imposed on a Technical Support Center (TSC). An onsite facility will continue to be maintained, from which effective direction can be given and effective control may be exercised during an emergency. The FCS emergency pl an will continue to maintain arrangements for requesting assistance and using resources from appropriate offsite support organizations. 53 E.8.a(ii) For nuclear power reactor licensees, a licensee onsite operational support center; NUREG-0696, "Functional Criteria for Emergency Response Facilities," (Reference 14) provides that the operational support center (OSC) is an onsite area separate from the Control Room and the TSC where licensee operations support personnel will assemble in an emergency. For a permanently shut down and defueled power plant, an OSC is no longer required to meet its original purpose of an assembly area for plant logistical support during an emergency. A single onsite facility will continue to be maintained at FCS, from which Control Room support, emergency mitigation, radiation monitoring, and effective control may be exercised during an emergency. LIC-16-0109

Page 31 54 E.8.b. For a nuclear power reactor licensee's emergency operations facility required by paragraph 8.a of this section, either a facility located between 10 miles and 25 miles of the nuclear power reactor site(s), or a primary facility located less than 10 miles from the nuclear power reactor site(s) and a backup facility located between 10 miles and 25 miles of the nuclear power reactor site(s). An emergency operations facility may serve more than one nuclear power reactor site. A licensee desiring to locate an emergency operations facility more than 25 miles from a nuclear power reactor site shall request prior Commission approval by submitting an application for an amendment to its license. For an emergency operations facility located more than 25 miles from a nuclear power reactor site, provisions must be made for locating NRC and offsite responders closer to the nuclear power reactor site so that NRC and offsite responders can interact face-to-face with emergency response personnel entering and leaving the nuclear power reactor site. Provisions for locating NRC and offsite responders closer to a nuclear power reactor site that is more than 25 miles from the emergency operations facility must include the following: In accordance with paragraph 8.e. the requirements of paragraph 8.b.(1) - (5) do not apply to the FCS EOF because it was an approved facility prior to December 23, 2011. However, the exemption is requested to clearly reflect that the requirement no longer applies to FCS in a permanently shut down and defueled condition. See also basis for 10 CFR 50.47(b)(3). 55 E.8.b.(1) Space for members of an NRC site team and Federal, State, and local responders 56 E.8.b.(2) Additional space for conducting briefings with emergency response personnel; LIC-16-0109

Page 32 57 E.8.b.(3) Communication with other licensee and offsite emergency response facilities; 58 E.8.b.(4) Access to plant data and radiological information; and 59 E.8.b.(5) Access to copying equipment and office supplies; 60 E.8.c. By June 20, 2012, for a nuclear power reactor licensee's emergency operations facility required by paragraph 8.a of this section, a facility having the following capabilities: (1) The capability for obtaining and displaying plant data and radiological information for each reactor at a nuclear power reactor site and for each nuclear power reactor site that the facility serves; See the basis for 10 CFR 50.47(b)(3). 61 E.8.c.(2) The capability to analyze plant technical information and provide technical briefings on event conditions and prognosis to licensee and offsite response organizations for each reactor at a nuclear power reactor site and for each nuclear power reactor site t hat the facility serves; and 62 E.8.c.(3) The capability to support response to events occurring simultaneously at more than one nuclear power reactor site if the emergency operations facility serves more than one site; and LIC-16-0109

Page 33 63 E.8.d. For nuclear power reactor licensees, an alternative facility (or facilities) that would be accessible even if the site is under threat of or experiencing hostile action, to function as a staging area for augmentation of emergency response staff and collectively having the following characteristics: the capability for communication with the emergency operations facility, control room, and plant security; the capability to perform offsite notifications; and the capability for engineering assessment activities, including damage control team planning and preparation, for use when onsite emergency facilities cannot be safely accessed during hostile action. The requirements in this paragraph 8.d must be implemented no later than December 23, 2014, with the exception of the capability for staging emergency response organization personnel at the alternative facility (or facilities) and the capability for communications wi th the emergency operations facility, control room, and plant security, which must be implemented no later than June 20, 2012. See the basis for Section IV.1 regarding hostile action. 64 E.8.e. A licensee shall not be subject to the requirements of paragraph 8.b of this section for an existing emergency operations facility approved as of December 23, 2011; See the basis for 10 CFR 50.47(b)(3) and Appendix E, Section IV.E.8.b. 65 E.9. At least one onsite and one offsite communications system; each system shall have a backup power source. All communication plans shall have arrangements for emergencies, including titles and alternates for those in charge at both ends of the communication links and the See the basis for 10 CFR 50.47(b) and (b)(10). FCS will maintain communications with the State of Nebraska, Washington County, and the NRC. The onsite response facilities will be combined into a single facility, as described in IV.E.8.a(ii). LIC-16-0109

Page 34 primary and backup means of communication. Where consistent with the function of the governmental agency, these arrangements will include: E.9.a. Provision for communications with contiguous State/local governments within the plume exposure pathway EPZ. Such communications shall be tested monthly. 66 E.9.b. Provision for communications with Federal emergency response organizations. Such communications systems shall be tested annually. No exemption is requested. 67 E.9.c. Provision for communications among the nuclear power reactor control room, the onsite technical support center, and the emergency operations facility; and among the nuclear facility, the principal State and local emergency operations centers, and the field assessment teams. Such communications systems shall be tested annually. FCS analyses demonstrate that 530 days (1 year, 165 days) after permanent cessation of power operations, no remaining postulated accidents at FCS will result in radiological releases requiring offsite protective actions, or in the event of beyond design basis accidents, 10 hours is available to take mitigative actions, and if needed, implement offsite protective actions using a comprehensive emergency management plan. Therefore, there is no need for the TSC, EOF, or field assessment teams. Also see justification for 10 CFR 50.47(b)(3). The provisions remaining in 10 CFR Part 50, Appendix E, Section IV.E.9.a, b, and d include the necessary requirements. Communication with State and local EOCs will be maintained to coordinate assistance on site, if required. LIC-16-0109

Page 35 68 E.9.d. Provisions for communications by the licensee with NRC Headquarters and the appropriate NRC Regional Office Operations Center from the nuclear power reactor control room, the onsite technical support center, and the emergency operations facility. Such communications shall be tested monthly. The functions of the Control Room, EOF, TSC, and OSC may be combined into one or more locations due to the smaller facility staff and the greatly reduced interaction required with State and local emergency response facilities. An onsite facility will continue to be maintained, from which effective command and control will be maintained and direction can be given during an emergency. FCS will maintain communications capability with the NRC. Also see the basis for 10 CFR 50.47(b). 69 F. Training F.1. The program to provide for: (a) The training of employees and exercising, by periodic drills, of emergency plans to ensure that employees of the licensee are familiar with their specific emergency response duties, and (b) The participation in the training and drills by other persons whose assistance may be needed in the event of a radiological emergency shall be described. This shall include a description of specialized initial training and periodic retraining programs to be provided to each of the following categories of emergency personnel: No exemption is requested. 70 F.1.i. Directors and/or coordinators of the plant emergency organization; 71 F.1.ii. Personnel responsible for accident assessment, including control room shift personnel; 72 F.1.iii. Radiological monitoring teams; LIC-16-0109

Page 36 73 F.1.iv. Fire control teams (fire brigades); 74 F.1.v. Repair and damage control teams; 75 F.1.vi. First aid and rescue teams; 76 F.1.vii. Medical support personnel; 77 F.1.viii. Licensee's headquarters support personnel; The number of staff at FCS during the decommissioning process will be small but commensurate with the need to safely store spent fuel at the facility in a manner that is protective of public health and safety. FCS will maintain a level of emergency re sponse that does not require additional response by headquarters personnel. The on-shift and emergency response positions are defined in the Permanently Defueled Emergency Plan and will be regularly tested through drills and exercises, audited, and inspected by FCS and the NRC. Also see the basis for 10 CFR 50.47(b). Therefore, exempting licensee's headquarters personnel from training requirements is considered to be reasonable. 78 F.1.ix. Security personnel. No exemption is requested. 79 F.1. In addition, a radiological orientation training program shall be made available to local services personnel; e.g., local emergency services/Civil Defense, local law enforcement personnel, local news media persons. Because there will no longer be any expected actions that must be taken by the public during an emergency, it is no longer necessary to pre-plan the dissemination of this information to the public or to provide radiological orientation training to local news media persons. LIC-16-0109

Page 37 The phrase "Civil Defense" is no longer a commonly used term and is no longer applicable as an example in the regulation. 80 F.2. The plan shall describe provisions for the conduct of emergency preparedness exercises as follows: Exercises shall test the adequacy of timing and content of implementing procedures and methods, test emergency equipment and communications networks, test the public alert and notification system, and ensure that emergency organization personnel are familiar with their duties. 3 FCS analyses demonstrate that 530 days (1 year, 165 days) after permanent cessation of power operations, no remaining postulated accidents at FCS will result in radiological releases requiring offsite protective actions, or in the event of beyond design basis accidents, 10 hours is available to take mitigative actions, and if needed, implement offsite protective actions using a comprehensive emergency management plan. Therefore, the public alert and notification system will not be used and no testing would be required. Also see the basis for 10 CFR 50.47(b). 81 F.2.a. A full participation exercise 4 which tests as much of the licensee, State, and local emergency plans as is reasonably achievable without mandatory public participation shall be conducted for each site at which a power reactor is located. Nuclear power reactor licensees shall submit exercise scenarios under § 50.4 at least 60 days before use in a full participation exercise required by this paragraph 2.a. FCS will continue to invite the State of Nebraska and Washington County to participate in the periodic drills and exercises conducted to assess their ability to perform responsibilities related to an emergency at FCS, to the extent defined by the FCS emergency plan. Because the need for offsite emergency planning is relaxed due to the low probability of the postulated accident or other credible events that would be expected to result in an offsite radioactive release that would exceed the EPA PAGs and the available time for event mitigation, no offsite emergency plans will be in place to test. The intent of submitting exercise scenarios at power reactors is to verify that licensees utilize different scenarios in order to prevent the preconditioning of responders at power reactors. For defueled sites, there are limited events that could occur and the previously routine 82 F.2.a.(i) For an operating license issued under this part, this exercise must be conducted within two years before the issuance of the first operating license for full power (one authorizing operation above 5 percent of rated power) of the first reactor and shall include participation by each State and local government within the plume exposure pathway EPZ LIC-16-0109

Page 38 and each state within the ingestion exposure pathway EPZ. If the full participation exercise is conducted more than 1 year prior to issuance of an operating licensee for full power, an exercise which tests the licensee's onsite emergency plans must be conducted within one year before issuance of an operating license for full power. This exercise need not have State or local government participation. progression to General Emergency in power reactor site scenarios is not applicable to a decommissioning site. OPPD considers FCS to be exempt from F.2.a.(i) - (iii) because FCS will be exempt from the umbrella provision of Section IV.F.2.a. 83 F.2.a.(ii) For a combined license issued under part 52 of this chapter, this exercise must be conducted within two years of the scheduled date for initial loading of fuel. If the first full participation exercise is conducted more than one year before the scheduled date for initial loading of fuel, an exercise which tests the licensee's onsite emergency plans must be conducted within one year before the scheduled date for initial loading of fuel. This exercise need not have State or local government participation. If FEMA identifies one or more deficiencies in the state of offsite emergency preparedness as the result of the first full participation exercise, or if the Commission finds that the state of emergency preparedness does not provide reasonable assurance that adequate protective measures can and w ill be taken in the event of a radiological emergency, the provisions of § 50.54(gg) apply. 84 F.2.a.(iii) For a combined license issued under part 52 of this chapter, if the applicant currently has an operating reactor at the site, an exercise, either full or partial participation, 5 shall be conducted for each subsequent reactor constructed on the LIC-16-0109

Page 39 site. This exercise may be incorporated in the exercise requirements of Sections IV.F.2.b. and c. in this appendix. If FEMA identifies one or more deficiencies in the state of offsite emergency preparedness as the result of this exercise for the new reactor, or if the Commission finds that the state of emergency preparedness does not provide reasonable assurance that adequate protective measures can and will be taken in the event of a radiological emergency, the provisions of § 50.54(gg) apply. 85 F.2.b. Each licensee at each site shall conduct a subsequent exercise of its onsite emergency plan every 2 years. Nuclear power reactor licensees shall submit exercise scenarios under § 50.4 at least 60 days before use in an exercise required by this paragraph 2.b. The exercise may be included in the full participation biennial exercise required by paragraph 2.c. of this section. In addition, the licensee shall take actions necessary to ensure that adequate emergency response capabilities are maintained during the interval between biennial exercises by conducting drills, including at least one drill involving a combination of so me of the principal functional areas of the licensee's onsite emergency response capabilities. The principal f unctional areas of emergency response include activities such as management and coordination of emergency response, accident assessment, event classification, notification of offsite authorities, assessment of the onsite and offsite impact of radiological releases, protective action recommendation development, See the basis for Section IV.F.2.a. The low probability of the postula ted accident or other credible events that would result in an offsite radioactive release that would exceed the EPA PAGs and the available time for event mitigation at FCS during decommissioning render the TSC, OSC, and EOF unnecessary. The principal functions required by regulation can be performed at a single onsite location that does not meet the requirements of the TSC, OSC, or EOF. The onsite response facilities at FCS will be combined into a single facility. FCS will continue to conduct biennial exercises and will invite the State of Nebraska and local support organizations (firefighting, law enforcement, and ambulance/medical services) to participate in periodic drills and exercises to assess their ability to perform responsibilities related to an emergency at FCS, to the extent defined by the FCS emergency plan. The intent of submitting exercise scenarios for use by power reactor licensees is to check that licensees utilize different scenarios in LIC-16-0109

Page 40 protective action decision making, plant system repair and mitigative action implementation. During these drills, activation of all of the licensee's emergency response facilities (Technical Support Center (TSC), Operations Support Center (OSC), and the Emergency Operations Facility (EOF)) would not be necessary, licensees would have the opportunity to consider accident management strategies, supervised instruction would be permitted, operating staff in all participating facilities would hav e the opportunity to resolve problems (success paths) rather than have controllers intervene, and the drills may focus on the onsite exercise training objectives. order to prevent the preconditioning of responders at power reactors. In FCS's permanently shut down and defueled condition, there are limited events that could occur and the previously routine progression to General Emergency in scenarios is not applicable to a decommissioning site. 86 F.2.c. Offsite plans for each site shall be exercised biennially with full participation by each offsite authority having a role under the radiological response plan. Where the offsite authority has a role under a radiological response plan for more than one site, it shall fully participate in one exercise every two years and shall, at least, partially participate in other offsite plan exercises in this period. If two different licensees each have licensed facilities located either on the same site or on adjacent, contiguous sites, and share most of the elements defining co-located licensees, 6 then each licensee shall: See the basis for Section IV.F.2.a. 87 F.2.c.(1) Conduct an exercise biennially of its onsite emergency plan; LIC-16-0109

Page 41 88 F.2.c.(2) Participate quadrennially in an offsite biennial full or partial participation exercise; 89 F.2.c.(3) Conduct emergency preparedness activities and interactions in the years between its participation in the offsite full or partial participation exercise with offsite authorities, to test and maintain interface among the affected State and local authorities and the licensee. Co-located licensees shall also participate in emergency preparedness activities and interaction with offsite authorities for the period between exercises; 90 F.2.c.(4) Conduct a hostile action exercise of its onsite emergency plan in each exercise cycle; and 91 F.2.c.(5) Participate in an offsite biennial full or partial participation hostile action exercise in alternating exercise cycles. 92 F.2.d. Each State with responsibility for nuclear power reactor emergency preparedness should fully participate in the ingestion pathway portion of exercises at least once every exercise cycle. In States with more than one nuclear power reactor plume exposure pathway EPZ, the State should rotate this participation from site to site. Each State with responsibility for nuclear power reactor emergency preparedness should fully participate in a hostile action exercise at least once every cycle and should fully participate See the basis for Section IV.2. LIC-16-0109

Page 42 in one hostile action exercise by December 31, 2015. States with more than one nuclear power reactor plume exposure pathway EPZ should rotate this participation from site to site. 93 F.2.e. Licensees shall enable any State or local government located within the plume exposure pathway EPZ to participate in the licensee's drills when requested by such State or local government. See the basis for Section IV.2. 94 F.2.f. Remedial exercises w ill be required if the emergency plan is not satisfactorily tested during the biennial exercise, such that NRC, in consultation with FEMA, cannot (1) find reasonable assurance that adequate protective measures can and will be taken in the event of a radiological emergency or (2) determine that the Emergency Response Organization (ERO) has maintained key skills specific to emergency response. The extent of State and local participation in remedial exercises must be sufficient to show that appropriate corrective measures have been taken regarding the elements of the plan not properly tested in the previous exercises. FEMA is responsible for evaluating the adequacy of an offsite response exercise. No action is expected from State or local government organizations in response to an event at a decommissioning site other than receiving notification of the emergency and firefighting, law enforcement, and ambulance/medical response servic es. Letters of Agreement will continue to be in place for those services. Offsite response organizations will continue to implement actions to protect the health and safety of the public as they would at any other industrial site. 95 F.2.g. All exercises, drills, and training that provide performance opportunities to develop, maintain, or demonstrate key skills must prov ide for formal critiques in order to identify weak or deficient areas that need correction. Any weaknesses or deficiencies that are identified in a critique of exercises, drills, or training must be corrected. No exemption is requested. LIC-16-0109

Page 43 96 F.2.h. The participation of State and local governments in an emergency exercise is not required to the extent that the applicant has identified those governments as refusing to participate further in emergency planning activities, pursuant to § 50.47(c)(1). In such cases, an exercise shall be held with the applicant or licensee and such governmental entities as elect to participate in the emergency planning process. No exemption is requested. 97 F.2.i. Licensees shall use drill and exercise scenarios that provide reasonable assurance that anticipatory responses will not result from preconditioning of participants. Such scenarios for nuclear power reactor licensees must include a wide spectrum of radiological releases and events, including hostile action. Exercise and drill scenarios as appropriate must emphasize coordination among onsite and offsite response organizations. At FCS, there will be limited events that could occur that could result in radiological releases that exceed the EPA PAGs and the previously routine progression to General Emergency in power reactor site scenarios will not be applicable. Therefore, FCS does not expect to demonstrate response to a wide spectrum of events. Also see the basis for 10 CFR 50.47(b) detailing the low likelihood of any credible accident resulting in radiological releases requiring offsite protective measures and basis for Section IV.1 regarding hostile action. 98 F.2.j. The exercises conducted under paragraph 2 of this section by nuclear power reactor licensees must provide the opportunity for the ERO to demonstrate proficiency in the key skills necessary to implement the principal functional areas of emergency response identified in paragraph 2.b of this section. Each exercise must provide the opportunity for the ERO to demonstrate key skills specific to emergency response duties in the control room, TSC, OSC, EOF, and joint information center. Additionally, in each eight calendar See the basis for Section IV.F.2. Periodic drills and exercises will be completed to demonstrate ERO proficiency in key skills necessary to implement the principal functional areas of emergency response as applicable for the permanently defueled plant status. Critiques will follow each drill or exercise activity. FCS will continue to invite the State of Nebraska and local support organizations to participate in the periodic drills and exercises to assess their ability to perform responsibilities LIC-16-0109

Page 44 year exercise cycle, nuclear power reactor licensees shall vary the content of scenarios during exercises conducted under paragraph 2 of this section to provide the opportunity for the ERO to demonstrate proficiency in the key skills necessary to respond to the following scenario elements: hostile action directed at the plant site, no radiological release or an unplanned minimal radiological release that does not require public protective actions, an initial classification of or rapid escalation to a Site Area Emergency or General Emergency, implementation of strategies, procedures, and guidance developed under § 50.54(hh)(2), and integration of offsite resources with onsite response. The licensee shall maintain a record of exercises conducted during each eight year exercise cycle that documents the content of scenarios used to comply with the requirements of this paragraph. Each licensee shall conduct a hostile action exercise for each of its sites no later than December 31, 2015. The first eight-year exercise cycle for a site will begin in the calendar year in which the first hostile action exercise is conducted. For a site licensed under Part 52, the first eight-year exercise cycle begins in the calendar year of the initial exercise required by Section IV.F.2.a. related to an emergency at FCS to the extent defined by the FCS emergency plan. 99 G. Maintaining Emergency Preparedness Provisions to be employed to ensure that the emergency plan, its implementing procedures, and emergency equipment and supplies are maintained up to date shall be described. No exemption is requested. LIC-16-0109

Page 45 100 H. Recovery Criteria to be used to determine when, following an accident, reentry of the facility would be appropriate or when operation could be resumed shall be described. No exemption is requested. 101 I. Onsite Protective Actions During Hostile Action By June 20, 2012, for nuclear power reactor licensees, a range of protective actions to protect onsite personnel during hostile action must be developed to ensure the continued ability of the licensee to safe ly shut down the reactor and perform the functions of the licensee's emergency plan. See the basis for Section IV.1. 102 10 CFR 50 Appendix E V. Implementing Procedures No less than 180 days before the scheduled issuance of an operating license for a nuclear power reactor or a license to possess nuclear material, or the scheduled date for initial loading of fuel for a combined license under part 52 of this chapter, the applicant's or licensee's detailed implementing procedures for its emergency plan shall be submitted to the Commission as specified in § 50.4. No exemption is requested. LIC-16-0109

Page 46 103 10 CFR 50 Appendix E VI. Emergency Response Data System 1. The Emergency Response Data System (ERDS) is a direct near real-time electronic data link between the licensee's onsite computer system and the NRC Operations Center that provides for the automated transmission of a limited data set of selected parameters. The ERDS supplements the existing voice transmission over the Emergency Notification System (ENS) by providing the NRC Operations Center with timely and accurate updates of a limited set of parameters from the licensee's installed onsite computer system in the event of an emergency. When selected plant data are not available on the licensee's onsite computer system, retrofitting of data points is not required. The licensee shall test the ERDS periodically to verify system availability and operability. The frequency of ERDS testing will be quarterly unless otherwise set by NRC based on demonstrated system performance. 2. Except for Big Rock Point and all nuclear power facilities that are shut down permanently or indefinitely, onsite hardware shall be provided at each unit by the licensee to interface with the NRC receiving system. Software, which will be made available by the NRC, will assemble the data to be transmitted and transmit data from each unit via an output port on the appropriate data system.The regulation that identifies the requirement to maintain the Emergency Response Data System (ERDS) is not applicable to nuclear power facilities that are permanently shut down. When FCS is permanently defueled, this system will no longer be necessary to transmit safety system parameter data. No exemption is requested because this change in the ERDS data requirement is identified in 10 CFR Part 50, Appendix E, Section VI.2. LIC-16-0109

Page 47 104 10 CFR 50 Appendix E Footnotes 3, 4, 5, and 6 are proposed for exemption. OPPD considers FCS to be exempt from Footnotes 3, 4, 5, and 6 because FCS will be exempt from the umbrella provisions of Section F.2. LIC-16-0109

Page 48 10 CFR 50.82(a)(2) specifies that the 10 CFR Part 50 license no longer authorizes operation of the reactor or emplacement or retention of fuel in the reactor vessel after docketing the certifications for permanent cessation of power operations and permanent removal of fuel from the reactor vessel in accordance with 10 CFR 50.82(a)(1)(i) and (ii). Following the termination of power operations at FCS and the permanent removal of the fuel from the reactor vessel, the postulated accidents involving failure or malfunction of the reactor and supporting structures, systems, and components are no longer applicable.

A summary of the postulated radiological accidents analyzed for the permanently shut down and defueled condition is presented below. According to the EPA, "Protective Action Guides and Planning Guidance for Radiological Incidents, Draft for Interim Use and Public Comment," dated March 2013 (Reference 10), Section 2.3.5, "PAGs and Nuclear Facilities Emergency Planning Zones (EPZ)," EPZs are not necessary at those facilities where it is not possible for PAGs to be exceeded offsite.

Section 5.0 of ISG-02 (Reference 1) indicates that site-specific analyses should demonstrate that: (1) the radiological consequences of the remaining applicable postulated accident would not exceed the limits of the EPA PAGs at the EAB; (2) in the event of a beyond design basis event resulting in the partial drain down of the SFP to the point that cooling is not effective, there is at least 10 hours (assuming an adiabatic heat up) from the time that the fuel is no longer being cooled until the hottest fuel assembly reaches 900 C; (3) adequate physical security is in place to assure implementation of security strategies that protect against spent fuel sabotage; and (4) in the unlikely event of a beyond design basis events resulting in a loss of all SFP cooling, there is sufficient time to implement pre-planned mitigation measures to provide makeup or spray to the SFP before the onset of a zirconium cladding ignition.

Table 3 contains a listing of seven analyses that are expected to be evaluated by a decommissioning power reactor licensee r equesting exemption of emergency planning requirements. The table also contains a description of how FCS addresses each of these

analyses. LIC-16-0109

Page 49 1 Applicable design DBAs (i.e., fuel handling accident in the spent fuel storage facility, waste gas system release, and cask handling accident if the cask handling system is not licensed as single-failure-proof) (Indicates that any radiological release would not exceed the limits of EPA PAGs at EAB); The postulated accident that will remain applicable to FCS and could contribute to dose upon implementation of the requested exemptions is the fuel handling accident (FHA) in the Auxiliary Building, where the SFP is located. The results of the analysis indicate that the dose at the EAB would not exceed the EPA PAGs within 10 days after permanent cessation of power operations. This analysis is described in Section 4.2. 2 Complete loss of SFP water inventory with no heat loss (adiabatic heatup) demonstrating a minimum of 10 hours is available before any fuel cladding temperature reaches 900 degrees Celsius from the time all cooling is lost (Demonstrates sufficient time to mitigate events that could lead to a zirconium cladding fire); FCS performed an analysis that conservatively evaluates the length of time (number of hours) it takes for uncovered spent fuel assemblies in the SFP to reach the temperature at which the zirconium cladding would fail. Based on the limiting fuel assembly for decay heat and adiabatic heat up analysis, at 530 days (1 year, 165 days) after permanent cessation of power operations, the time for the hottest fuel assembly to reach 900°C is 10 hours after spent fuel cooling is lost. This analysis is described in Section 4.3 and is included in Attachment 2. 3 Loss of SFP water inventory resulting in radiation exposure at

the EAB and control room; (Indicates that any release is less

than EPA PAGs at EAB); and FCS performed an analysis to determine the offsite radiological impact of a complete loss of SFP water. It was determined that the gamma radiation dose rate at the EAB would be limited to small fractions of the EPA PAG exposure levels. This analysis is described in Section 4.4 and is included in Attachment 3. 4 Considering the site-specific seismic hazard, either an evaluation demonstrating a high confidence of a low-probability (less than 1 x 10-5 per year) of seismic failure of the spent fuel storage pool structure or an analysis demonstrating the fuel has decayed sufficiently that natural air flow in a completely drained pool would maintain peak cladding temperature below 565 degrees Celsius (the point of incipient cladding damage) (Indicates that any release is less than EPA PAGs at EAB). FCS conducted a seismic evaluation in response to a NRC request for information pursuant to 10 CFR 50.54(f) regarding Recommendation 2.1 of the Near-Term Task Force (NTTF) Review of Insights from the Fukushima Dai-ichi Accident. The seismic evaluation included all structures including the SFP, and was prepared and submitted for NRC review. The OPPD submittal (LIC-14-0047) (Reference 15) documents the seismic evaluation in conformance with NTTF Recommendation 2.1 including the high confidence of a low-probability of seismic failure (HCLPF) values and the 1 x 10 -5 per year hazard level. The Staff review of the NTTF submittal, specifically for the SFP Evaluation associated with the reevaluated seismic hazard implementing NTTF Recommendation 2.1 (CAC No. MF3735) is documented in NRC-16-0068 (ML16182A361) (Reference 16). The NRC staff concluded that the assessment was performed consistent with the NRC-endorsed (ML15350A158) (Reference 17) SFP Evaluation Guidance Report (Reference 18) and provided sufficient information, including the SFP LIC-16-0109

Page 50 integrity evaluation, to meet the SFP Evaluation Guidance (Item 9 in Enclosure 1 of the NRC's 50.54(f) letter), thus supporting SDA No. 6 of NUREG-1738. Therefore, the air-cooled analysis is not being performed. The analysis is described in SDA-6 of Table 5. 5 The analyses and conclusions described in NUREG-1738 are predicated on the risk reduction measures identified in the study as Industry Decommissioning Commitments (IDC) and Staff Decommissioning Assumptions (SDA), listed in Tables 4.1-1 and 4.1-2 of that document. The staff should ensure that the licensee has addressed these IDCs and SDAs for the decommissioning site if they are storing fuel in an

SFP. IDCs and SDAs are addressed in Section 4.5 and Tables 4 and

5. 6 Verify that the licensee presents a determination that there is sufficient resources and adequately trained personnel available on-shift to initiate mitigative actions within the 10-hour minimum time period that will prevent an offsite radiological release that exceeds the EPA PAGs at the EAB. The onsite restoration plans for repair of the SFP cooling system and to provide makeup water to the SFP are incorporated into FCS procedures. There are multiple ways to initiate mitigative actions and add makeup water to the SFP within the 10-hour minimum time period with or without entry to the SFP floor. Refer to SDA 2 in Table 5. 7 Verify that mitigation strategies are consistent with that required by the Permanently Defueled Technical Specifications or by retained license conditions. FCS maintains procedures and strategies for the movement of any necessary portable equipment that will be relied upon for mitigating the loss of SFP water. These mitigative strategies were developed in response to 10 CFR 50.54(hh)(2) and are maintained in accordance with License Condition 3.G of the

FCS Renewed Facility Operating License. These diverse strategies provide defense-in-depth and ample time to provide makeup water or spray to the SFP prior to the onset of zirconium cladding ignition when considering very low probability beyond design basis events affecting the SFP. Refer to SDA 4 in Table 5. LIC-16-0109

Page 51 While spent fuel remains in the SFP, the only postulated accident that will remain applicable to FCS that could contribute to dose upon implementation of the requested exemptions is the FHA in the Auxiliary Building, where the SFP is located. FCS maintains an analysis (Calculation FC08557, Fuel Handling Accident in the Spent Fuel Pool Site Boundary and Control Room Dose (Reference 29)) that has determined the EAB dose due to a FHA occurring in the Auxiliary Building. The FHA analysis is performed using selective application of the Alternative Source Term (AST), the guidance in Regulatory Guide 1.183, Appendix B (Reference 19), and Total Effective Dose Equivalent (TEDE) dose criteria. The results of the analysis indicate that the EAB dose is within regulatory allowable limits for a FHA occurring in the Auxiliary Building within 10 days after shutdown.

The results of this analysis may be applied after November 13, 2016, the date that OPPD certified that all fuel has been permanently removed from the reactor vessel and placed in the SFP (Reference 4). With respect to beyond design basis events, FCS analyzed a partial drain down of the SFP water that would effectively impede any decay heat removal (adiabatic heatup). The analysis (Calculation FC08104, Maximum Cladding Temperature Analysis for Adiabatic Heat-up of Spent Fuel Assembly (Reference 30)) compares the conditions for the hottest fuel assembly stored in the FCS SFP to a criterion proposed in SECY-99-168 (Reference 20) applicable to offsite emergency response for a unit in the decommissioning process. This criterion considers the time for the hottest assembly to heat up from 30°C to 900°C adiabatically. If the heat up time is greater than 10 hours from the time spent fuel cooling is lost, then offsite emergency preplanning involving the plant is not necessary.

Based on the limiting fuel assembly decay heat and adiabatic heat up analysis, 530 days (1 year, 165 days) after permanent cessation of power operations, the time for the hottest fuel assembly to reach 900°C is 10 hours after the assemblies have been uncovered. As stated in NUREG-1738, "Technical Study of Spent Fuel Pool Accident Risk at Decommissioning Nuclear Power Plants" (February 2001) (Reference 12), 900°C is an acceptable temperature to use for assessing the onset of fission product release under transient conditions (to establish the critical decay time for determining availability of 10 hours to evacuate) if fuel and cladding oxidation occurs in air. Because of the length of time it would take for the adiabatic heat up to occur, there is ample time to respond to any partial drain down event that might cause such an occurrence by restoring SFP cooling or makeup, or providing spray. As a result, the likelihood that such a scenario would progress to a zirconium fire is not deemed credible. The analysis is included in Attachment 2.

LIC-16-0109

Page 52 FCS analyzed a drain down event of the SFP to determine a dose rate curve at the EAB and Control Room. NUREG-0586, "Final Gener ic Environmental Impact Statement on Decommissioning of Nuclear Facilities," (Reference 21) Supplement 1, Section 4.3.9, identifies that a SFP drain down event is a beyond design basis event. Although Calculation FC08104, Maximum Cladding Temperature Analysis for Adiabatic Heat-up of Spent Fuel Assembly, demonstrated a significant release of radioactive material from the spent fuel is not possible in the absence of water cooling after 530 days (1 year, 165 days) following permanent cessation of power operations, the potential exists for radiation exposure to an offsite individual in the event that shielding of the fuel is lost. The SFP water and the concrete pool structure serve as radiation shielding. A loss of water shielding above the fuel could increase the offsite radiation levels because of the gamma rays streaming up out of the SFP being scattered back to a receptor at the site boundary.

The offsite and Control Room radiological impacts of a postulated complete loss of SFP water were assessed in Calculation FC08513, EAB Radi ation Shine Dose 18 Months Post Shutdown with the SFP Drained (Reference 31). It was determined that the gamma radiation dose rate at the EAB would be limited to small fractions of the EPA PAGs. The EPA PAGs were developed to respond to a mobile airborne plume that could transport and deposit radioactive material over a large area. In contrast, the radiation field formed by scatter from a drained SFP would be stationary rather than moving and would not cause transport or deposition of radioactive materials. The extended period required to exceed the EPA PAG limit of 1 Rem TEDE would allow sufficient time to develop and implement onsite mitigative actions and provide confidence that additional offsite measures could be taken without planning if efforts to reestablish shielding

over the fuel are delayed. Based on the data presented in Calculation FC08513, 530 days (1 year, 165 days) following permanent cessation of operations, the dose rate in the Control Room during an event involving a complete loss of SFP water will be below 2.32 x 10 -3 mRem/hr, which is less than 15 mRem/hr. Calculation FC08513 is included in Attachment 3 and 4.

Although the limited scope of the postulated accident and beyond design basis events that remain applicable to FCS justify a reduction in the necessary scope of emergency response capabilities, OPPD also evaluated the IDCs and SDAs contained in NUREG-1738 (Reference 12).

LIC-16-0109

Page 53 NUREG-1738 contains the results of the NRC staff's evaluation of the potent ial accident risk in SFPs at decommissioning plants in the United States. The study was undertaken to support development of a risk-informed technical basis for reviewing regulatory exemption requests and a regulatory framework for integrated rulemaking. The NRC staff performed analyses and sensitivity studies on evacuation timing to assess the risk significance of relaxed offsite emergency preparedness requirements during decommissioning. The staff based its sensitivity assessment on the guidance in Regulatory Guide (RG) 1.174, "An Approach for Using Probabilistic Risk Assessment In Risk-Informed Decisions on Plant-Specific Changes to the Licensing Basis" (Reference 22). The staff's analyses and conclusions apply to decommissioning facilities with SFPs that meet the design and operational characteristics assumed in the risk analysis.

The study found that the risk of a potential SFP accident at decommissioning plants is low and well within the Commission's Safety Goals. The risk is low because of the very low likelihood of a zirconium fire (resulting from a postulated irrecoverable loss of SFP cooling water inventory) even though the consequences from a zirconium fire could be serious.

The study provided the following assessment:

The Executive Summary in NUREG-1738 states, in part, "the staff's analyses and conclusions apply to decommissioning facilities with SFPs that meet the design and operational characteristics assumed in the risk analysis. These characteristics are identified in the study as IDCs and SDAs. Provisions for confirmation of these characteristics would need to be an integral part of rulemaking." The IDCs and SDAs are listed in Tables 4.1-1 and 4.1-2, respectively, of NUREG-1738. Tables 4 and 5 describe how the FCS SFP meets or compares with each of these IDCs (Table 4) and SDAs (Table 5). Attachment 4 includes a new regulatory commitment to update the FCS USAR with this information.

LIC-16-0109

Page 54 NUREG-1738 (Reference 12) identifies beyond design basis seismic events as the dominant contributor to events that could result in a loss of SFP coolant that uncovers fuel for plants in the Central and Eastern United States. Additionally, NUREG-1738 identifies a zirconium fire resulting from a substantial loss-of-water inventory from the SFP, as the only postulated scenario at a decommissioning plant that could result in a significant offsite radiological release. The scenarios that lead to this condition have very low frequencies of occurrence (i.e., on the order of one to tens of times in a million years) and are considered beyond design basis events because the SFP and attached systems are designed to prevent a substantial loss of coolant inventory under accident conditions. However, the consequences of such accidents could potentially lead to an offsite radiological dose in excess of the EPA PAGs (Reference 10) at the

EAB.

However, the risk associated with zirconium cladding fire events decreases as the spent fuel ages, decay time increases, decay heat decreases, and short-lived radionuclides decay away. As decay time increases, the overall risk of a zirconium cladding fire continues to decrease due to two factors: (1) the amount of time available for preventative actions increases, which reduces the probability that the actions would not be successful; and (2) the increased likelihood that the fuel is able to be cooled by air, which decreases the reliance on actions to prevent a zirconium fire. The results of research conducted for NUREG-1738 and NUREG-2161, "Consequence Study of a Beyond-Design-Basis Earthquake Affecting the Spent Fuel Pool for a U.S. Mark I Boiling Water Reactor," dated September 2014 (Reference 23), suggest that, while other radiological consequences can be extensive, a postulated accident scenario leading to a SFP zirconium fire, where the fuel has had significant decay time, will have little potential to cause offsite early fatalities, regardless of the type of offsite response (i.e., formal offsite radiological emergency preparedness plan or Comprehensive Emergency Management Plan).

The purpose of NUREG-2161 (Reference 23) was to determine if accelerated transfer of older, colder spent fuel from the SFP at a reference plant to dry cask storage significantly reduces the risks to public health and safety. The study states that "this study's results are consistent with earlier research studies' conclusions that spent fuel pools are robust structures that are likely to withstand severe earthquakes without leaking cooling water and potentially uncovering the spent fuel. The study shows the likelihood of a radiological release from the spent fuel after the analyzed severe earthquake at the reference plant to be about one time in 10 million years or lower. If a leak and radiological release were to occur, this study shows that the individual cancer fatality risk for a member of the public is several orders of magnitude lower than the Commission's Quantitative Health Objective of two in one million (2 x 10 -6/year). For such a radiological release, this study shows public and environmental effects are generally the same or smaller than earlier studies." The reference plant for the study (a General Electric Type 4 BWR with a Mark I containment)generated approximately 3500 MWt and the SFP contained 2844 fuel assemblies. FCS was licensed to generate 1500 MWt, and the SFP has the capacity to hold 1083 fuel assemblies. The SFP holds 944 fuel assemblies following permanent cessation of power operations and transfer of all fuel from the reactor vessel to the SFP. Based on these differences, the risk and the consequences of an event involving the SFP at FCS are lower than those in the NUREG-

2161 study.

Page 55 FCS conducted a seismic evaluation in response to a NRC request for information pursuant to 10 CFR 50.54(f) regarding Recommendation 2.1 of the NTTF Review of Insights from the Fukushima Dai-ichi Accident. The seismic evaluation included all structures including the SFP, and was prepared and submitted for NRC revi ew. The OPPD submittal (LIC-14-0047) (Reference 15) documents the seismic evaluation in conformance with NTTF Recommendation 2.1 including the HCLPF values and the 1 x 10 -5 per year hazard level. The Staff review of the NTTF submittal, specifically for the SFP Evaluation associated with the reevaluated seismic hazard implementing NTTF Recommendation 2.1 (CAC No. MF3735) is documented in NRC-16-0068 (ML16182A361) (Reference 16). The NRC staff concluded that the assessment was performed consistent with the NRC-endorsed (ML15350A158) (Reference 17) SFP Evaluation Guidance Report (Reference 18) and provided sufficient information, including the SFP integrity evaluation, to meet the SFP Evaluation Guidance (Item 9 in Enclosure 1 of the NRC's 50.54(f) letter), thus supporting SDA No. 6 of NUREG-1738. Based on the above, FCS has demonstrated that no credible accident will result in radiological releases requiring offsite protective actions. Additionally, there is sufficient time, resources and personnel available to initiate mitigative actions that will prevent an offsite release that exceeds EPA PAGs. LIC-16-0109

Page 56 1 Cask drop analyses will be performed or single failure-proof cranes will be in use for handling of heavy loads (i.e., phase II of NUREG-0612 will be implemented). The FCS Auxiliary Building crane with its main hook is used to move the spent fuel casks into the SFP. The capacity of the crane lifting system using the main hook is 106 tons to accommodate the ISFSI spent fuel casks. The design of this lifting system is single failure-proof. Therefore, the likelihood of dropping the spent fuel casks into the SFP or in the Auxiliary Building is extremely low. The crane, main hook and lifting system meet the requirements of NUREG-0612, NUREG-0554, ANSI-30.2-1976, Regulatory Guide 1.104, CMAA-70, and ASME NOG-1-2004 as a single failure-proof system. The licensing basis for the control of heavy loads associated with the Refueling Area Crane consists of a commitment to NUREG-0612, "Control of Heavy Loads at Nuclear Power Plants," -Phase 1 requirements. The Auxiliary Building Crane large hook conforms to the design requirements of NUREG-0554 "Single-Failure-Proof Cranes for Nuclear Power Plants", as demonstrated through conformance with the generic topical report for nuclear safety-related X SAM crane EDR-1. The basis for FCS's defense-in-depth approach for the control of heavy loads in the SFP area consists of preventing load drops due to crane failure, rigging failure, or human error through a combination of the use of the single failure-proof crane and compliance with the following guidelines from NUREG-0612. 1. Definition of safe load paths 2. Development of load handling procedures 3. Periodic inspection and testing of cranes 4. Qualifications, training and specified conduct of operators

5. Special lifting devices should satisfy the guidelines of ANSI N14.6 6. Lifting devices that are not specially designed should be installed and used in accordance with the guidelines of ANSI B30.9

7. Design of cranes to ANSI B30.2 or CMAA-70 Rigging equipment meeting Guideline Nos. 5 and 7 must be used to maintain single failure-proof status. The licensing basis with regard to these guidelines requires that off the shelf and specially designed rigging equipment meet one of the following requirements:

LIC-16-0109

Page 57 1. Provide redundancy or duality such that a single lift point failure will not result in uncontrolled lowering of the load; lift points must have a design factor of safety with respect to ultimate strength of five times the maximum load. The following is an example for meeting this requirement. Lifting a 10,000 lb. load requires two sets of rigging, each rated for at least 10,000 lbs. (with a 5:1 factor of safety). The total combined factor of safety would then be 10:1. or 2. A non-redundant or non-dual lift point system must have a design safety factor of ten times the maximum load. This can be met by using one set of rigging rated at 20,000 lbs. (with a 5:1 factor of safety) to lift a 10,000 lb. load. The total combined factor of safety would then be 10:1. Because the auxiliary building crane is single failure-proof, an accidental load drop is considered not to be a credible event such that condition 5.1.2(1) of NUREG-0612 is satisfied and analysis of cask drop accidents in accordance with condition 5.1.2(4) of NUREG-0612 is not required. 2 Procedures and training of personnel will be in place to ensure that onsite and offsite resources can be brought to bear during an event. FCS procedures are in place to ensure onsite and offsite resources can be brought to bear during an event, including: AOP-01, Acts of Nature , AOP-06, Fire Emergency, AOP-37, Security Event, AOP-31, 161kV Grid Malfunctions, AOP-38, Blair Water Main Trouble, and OCAG-1/2/3/4, Operational Contingency Action Guidelines. EP-FC-112-100-F-01, Command and Control Checklist - Control Room, directs the Control Room to implement EP-FC-114-100, Off-Site notifications. The Shift Manager or other designated Control Room personnel activates the ERO Notification System in accordance with EP-FC-112-100-F-06, ERO Notification or Augmentation. This process ensures FCS emergency personnel report to their proper locations. Periodic Emergency Plan drills are conducted wi th opportunities for off-site response organization participation in accordance with EP-FC-122, Drills and Exercises. Training requirements are outlined in EP-FC-10, Emergency Preparedness Program Description, and executed per TQ-FC-113, ERO Training and Qualification. The post-shutdown on-shift operations staff, including Certified Fuel Handlers (CFH) and Non-Certified Operators (NCO) will be appropriatel y trained on these procedures. The FCS CFH training program was submitted for NRC review and approval by letter dated January 15, 2016 (Reference 24). Finally, the systematic approach to training is implemented to ensure Operations and other appropriate personnel receive initial and continuing training on B.5.b event related procedures LIC-16-0109

Page 58 and strategies credited in the Mitigation Strategy License Condition under 10 CFR 50.54 (hh)(1), 10CFR 50.54 (hh)(2), and Attachment 2 to NRC order EA-06-137. Additionally, ERO decision-makers receive initial and continuing training in accordance with TQ-AA-113, ERO Training and Qualification. Training is provided on strategies and command and control aspects of a 10 CFR 50.54 (hh)(1) and 10 CFR 50.54(hh)(2) B.5.b event that includes the following: Initial operational response, Initial damage assessments, appropriate offsite notifications, an d notification of the ERO. 3 Procedures will be in place to establish communication between onsite and offsite organizations during severe weather and seismic events. FCS maintains the following procedures to provide guidance for establishing and maintaining communications between offsite agencies and the onsite ERO during severe weather and seismic events: 1.

The FCS design is consistent with this IDC, which includes multiple readouts and alarms for SFP temperature, water level, and area radiation monitors. Additionally, FCS maintains procedure AOP-36, Loss of Spent Fuel Pool Cooling, to guide the response in the event that cooling or water level is lost in the SFP. The Control Room and local operating panel (AI-100) are also alerted by alarm when a SFP cooling pump is not running. This allows for prompt operation action prior to having an issue with cooling. SFP temperature indication in the Control Room and remote locations is monitored from a point in the SFP cooling path on the outlet of the heat exchanger. Additionally, the Component Cooling water temperature through the heat exchanger is also monitored. Both of these indications will cause alarms in the Control Room on high temperature. Additionally, temperature indications from the 1013-, 1022-, and 1035-foot elevations of the SFP are displayed and recorded on the Emergency Response Facility (ERF) computer. These indications have high, high-high, and rate of change alarms. SFP water level is monitored each shift as part of required Operator rounds using an installed level indication and visual verification. This level indication also drives a Control Room alarm on both high and low level. There is also a ruler mounted indication in the SFP for monitoring level locally. In the event of a beyond design basis flooding event, additional level indication is installed in the SFP as driven through OCAG-2/3/4. SFP area radiation levels are monitored via area radiation monitors that provide indication and alarm annunciation in the Control Room. A local alarm to notify personnel of high area radiation levels is also in place. 6 SFP seals that could cause leakage leading to fuel uncovery in the event of seal failure shall be self-limiting to leakage or otherwise engineered so that drainage cannot occur. The design of the SFP and its cooling system and connections to the pool are such that the SFP cannot be drained below the level of the top of the stored fuel when in its storage rack. Additionally, drainage grooves are provided behind the stainless steel liner to permit detection of any liner leakage. On a quarterly basis, the liner leakage is evaluated per preventative maintenance work instructions. The hydraulic design of the Spent Fuel Pool Cooling System is such that the single failure of any line or other single component will not drain the SFP. LIC-16-0109

Page 60 The top of the fuel assemblies in the rack is at elevation 1008'-6", which is the same as the elevation of the bottom of the gate connecting the pool with the fuel transfer canal. A plate has been installed across the bottom of the gate to raise the minimum possible water level in the pool to 1009'-8.5". The gate is a taper design that is 7'4" wide at the top and tapers to 4'6" wide at the bottom. The gate is constructed of carbon steel with stainless steel plate. The lower one-third is filled with concrete to withstand hydrostatic forces. The gate is sealed using a rubber gasket at the gate-to-SFP liner interface. This design provides a passive seal (e.g., in comparison to the active seal of designs using inflatable bladders). The SFP cooling system has two suction points. The upper suction line enters at elevation 1034'-0" and is the normal suction point. The lower suction line enters at elevation 1011'-4" which is above the top of the stored fuel. The lower suction normally has a closed valve, but if the valve is inadvertently left open, the upper cooling water suction line and strainer would serve as a vacuum breaker and prevent draining of the pool. A rupture of the suction line upstream of the valve would only drain the pool to a level still above the spent fuel assemblies. The SFP cooling water discharges to the pool at 1034'-0" and ends at 1031'-7" (a 90 degree elbow to direct flow downward). The line is provided with a 1/2 inch hole to act as a vacuum breaker in the event that a discharge piping rupture occurs causing the line to act as a siphon. The transfer tube is isolated by a flange on the reactor side and by gate valve in the fuel transfer canal. The isolation valve is a 36-inch, double sliding stem gate valve, manually operated from the 1038-foot level of the spent fuel deck area. 7 Procedures or administrative controls to reduce the likelihood of rapid draindown events will include (1) prohibitions on the use of pumps that lack adequate siphon protection or (2) controls for pump suction and discharge points. The functionality of anti-siphon devices will be periodically verified. Administrative controls are in place that drive procedure use and adherence and risk management. Specifically, HU-AA-104-101, Procedure Use and Adherence, establishes the expectations and requirements for procedure adherence and usage for all personnel performing activities. Additionally, all work activities are subject to the work process controls and Integrated Risk Management per WC-AA-104 where the activities are analyzed and managed for risk (e.g., address SFP activities). The SFP is designed to reduce the likelihood of rapid drain down events. Specifically, the SFP cooling lower suction, which is st ill well above the top of stored f uel, has a manual valve that is controlled/locked closed. If the valve were to be inadvertently left open, the upper suction line and strainer would serve as a vacuum breaker and prevent draining of the SFP. A rupture of the suction line upstream of the valve would only drain the SFP to a level still above the spent fuel assemblies. The SFP cooling discharge line is provided with a 1/2 inch hole to act as a vacuum breaker in the event that a discharge piping rupture occurs causing the line to act as a siphon. LIC-16-0109

Page 61 FCS maintains an administrative requirement that the SFP be maintained at an elevation of 1033' to 1037'-9" at all times. This corresponds to 37.5' and 42.3' on local level indication. This administrative requirement is placed in procedures as a precaution/limitation. Additionally, the ISFSI equipment design is such that there are no SFP operations that have the potential to cause a rapid drain down. The ISFSI controlling procedures carefully control water volume move in and out of the SFP during operations. 8 An onsite restoration plan will be in place to provide repair of the SFP cooling systems or to provide access for makeup water to the SFP. The plan will provide for remote alignment of the makeup source to the SFP without requiring entry to the refuel floor. FCS practices align with this IDC. The onsite restoration plan for repair of the SFP cooling system and for makeup water to the SFP are incorporated into procedures AOP-36, Loss of Spent Fuel Pool Cooling, and OCAG-1, Operational Contingency Action Guideline ***10 CFR 2.390**** (also OCAGs-2/3/4) AOP-36 establishes multiple makeup sources from onsite that include: 1. Demineralized Water 2. Blair Water (city water) 3. Fire Water Storage Tank 4. Diesel Fire Pump (river water) OCAG-1 establishes multiple onsite and offsite makeup sources. OCAG-2/3/4 establish additional makeup sources from onsite in the event of major flooding. There are multiple ways to add makeup water to the SFP with or without entry to the pool floor as depicted above. 9 Procedures will be in place to control SFP operations that have the potential to rapidly decrease SFP inventory. These administrative controls may require additional operations or management review, management physical presence for designated operations or administrative limitations such as restrictions on heavy load movements. Administrative controls are in place that drive procedure use and adherence and risk management. Specifically, HU-AA-104-101, Procedure Use and Adherence, establishes the expectations and requirements for procedure adherence and usage for all personnel performing activities. Additionally, all work activities are subject to the work process controls and Integrated Risk Management per WC-AA-104 where the activities are analyzed and managed for risk (e.g., address SFP activities). FCS maintains an administrative requirement that the SFP be maintained at an elevation of 1033' to 1037' 9" at all times. This corresponds to 37.5' and 42.3' on local level indication. This administrative requirement is placed in procedures as a precaution/limitation. Additionally, the ISFSI equipment design is such that there are no SFP operations that have the potential to LIC-16-0109

Page 62 cause a rapid drain down. The ISFSI controlling procedures carefully control water volume move in and out of the SFP during operations. The fuel handling procedures at FCS require additional personnel to verify fuel assemblies are correctly grappled prior to movement. Additionally, the fuel handling tools are designed with a J-Hook that prevents a fuel assembly from separating from the tool. The heavy loads and crane usage around the SFP are controlled through GM-OI-HE-002, Auxiliary Building Crane HE-2 No rmal Operation. Attachment 13 of this procedure summarizes the licensing basis for the auxiliary building crane being single failure-proof. FCS maintains a defense-in-depth approach to control heaving loads in the SFP area. The basis for FCS's defense-in-depth approach for the control of heavy loads in the SFP area consists of preventing load drops due to crane failure, rigging failure, or human error through a combination of the use of the single failure-proof crane and through compliance with the following guidelines from NUREG-0612. 1. Definition of safe load paths 2. Development of load handling procedures 3. Periodic inspection and testing of cranes 4. Qualifications, training and specified conduct of operators

5. Special lifting devices should satisfy the guidelines of ANSI N14.6 6. Lifting devices that are not specially designed should be installed and used in accordance with the guidelines of ANSI B30.9

7. Design of cranes to ANSI B30.2 or CMAA-70 Rigging equipment meeting guideline Nos. 5 and 7 must be used to maintain single failure-proof status. The licensing basis with regard to these guidelines requires that off the shelf and specially designed rigging equipment meet one of the following requirements: 1. Provide redundancy or duality such that a single lift point failure will not result in uncontrolled lowering of the load; lift points must have a design factor of safety with respect to ultimate strength of five times the maximum load. The following is an example for meeting this requirement. Lifting a 10,000 lb. load requires two sets of rigging, each rated for at least 10,000 lbs. (with a 5:1 factor of safety). The total combined factor of safety would then be 10:1. or LIC-16-0109

Page 63 2. A non-redundant or non-dual lift point system must have a design safety factor of ten times the maximum load. This can be met by using one set of rigging rated at 20,000 lbs. (with a 5:1 factor of safety) to lift a 10,000 lb. load. The total combined factor of safety would then be 10:1. 10 Routine testing of the alternative fuel pool makeup system components will be performed and administrative controls for equipment out of service will be implemented to provide added assurance that the components would be available, if needed. FCS practices align with this IDC. SFP makeup strategies are outlined in AOP-36 and OCAG documents as previously outlined. One of the primary makeup strategies is from the Fire Protection System. The Fire Protection System has redundant pumping capability and power supplies to ensure alternate SFP makeup functions. The system is supplied by redundant pumps, one diesel driven and one electric motor driven, each design rated for 2000 gpm at 125 psig discharge pressure. Both pumps take suction from the plant intake cooling water structure from the Missouri River. The fire protection header is normally maintained at greater than 130 psig by a jockey pump. If pressure decreases in the system, the fire pumps are automatically started by their initiation logic to maintain the fire protection system header pressure. The electric motor driven pump starts when system pressure decreases to 110 psig and the diesel driven pump is started in 10 seconds if the electric motor driven pump does not start or when system pressure drops to 100 psig. The onsite Fire Truck can also take suction from the Missouri River or a hydrant to provide an alternate source of makeup water to the SFP. The Fire Protection System can also be cross-connected with the Blair Water System (city water). The Fire Protection System provides defense-in-depth, and is routinely tested to ensure capability is maintained. OCAG-1 establishes multiple makeup sources from onsite and offsite as discussed previously. OP-AA-201-010-1001 contains the maintenance, verification and testing requirements of B.5.b Equipment. Administrative controls are in place that drive procedure use and adherence and risk management. Specifically, HU-AA-104-101, Procedure Use and Adherence, establishes the expectations and requirements for procedure adherence and usage for all personnel performing activities. Additionally, all work activities are subject to the work process controls and Integrated Risk Management per WC-AA-104 where the activities are analyzed and managed for risk (e.g., address SFP activities). Once all fuel is removed from containment, a large inventory of water above the fuel still exists to extend the time to boil or until fuel is uncovered. The SFP cooling system has far fewer interfaces than the RCS that could impact the ability of the system to perform its function; however, there are also fewer redundant makeup sources available which constitutes a higher risk. Therefore, SO-O-21, Shutdown Operations Protection Plan, has special requirements to adhere to or LIC-16-0109

Page 64 additional clarifying information when crediting or considering available systems and equipment to fulfill SFP only shutdown conditions.

LIC-16-0109

Page 65 1 Licensee's SFP cooling design will be at least as capable as that assumed in the risk assessment, including instrumentation. Licensees will have at least one motor-driven and one diesel-driven fire pump capable of delivering inventory to the SFP. The FCS design is consistent with this SDA. The SFP cooling system, SFP racks, and Auxiliary Building which houses the SFP were designed and constructed to Seismic Class I standards. The SFP cooling system heat exchangers are ultimately cooled by the Missouri River (ultimate heat sink) using redundant pumps that are supplied by redundant power sources. The pumps are normally powered from offsite power, but can be supplied from an alternate reliable power source. The makeup system is adequate to provide water at the required capacity. The SFP makeup system can provide 500 gpm, and additional water is available from both the demineralized water system and the fire protection system using hoses. The station design includes a motor-driven fire pump and a diesel-driven fire pump, both of which will be maintained until all fuel is removed from the SFP. Each fire pump has the capability to deliver 200 to 500 gallons per minute (gpm) of makeup water to the SFP. FCS also has a pumper type fire truck, which is able to provide 200 to 500 gpm of makeup water to the SFP. 2 Walk-downs of SFP systems will be performed at least once per shift by the operators. Procedures will be developed for and employed by the operators to provide guidance on the

capability and avail ability of onsite and offsite inventory makeup sources and time available to initiate these sources for various loss of cooling or inventory events. FCS operators perform a walk down of the SFP systems once per shift as driven by operator rounds and by surveillance testing procedure. The onsite restoration plan for repair of the SFP cooling system and for makeup water to the SFP are incorporated into procedures AOP-36, Loss of Spent Fuel Pool Cooling, and OCAG-1, Operational Contingency Action Guideline ***10CFR2.390****. (also OCAG-2/3/4) AOP-36 establishes multiple makeup sources from onsite that include: 1. Demineralized Water

2. Blair Water (city water)

3. Fire Water Storage Tank 4. Diesel Fire Pump (river water)

OCAG-1 establishes multiple onsite and offsite makeup sources. OCAG-2/3/4 establish additional makeup sources from onsite in the event of major flooding. LIC-16-0109

Page 66 There are multiple ways to add makeup water to the SFP with or without entry to the pool floor. 3 Control room instrumentation that monitors SFP temperature and water level will directly measure the parameters involved. Level instrumentation will provide alarms at levels associated with calling in offsite resources and with declaring a general emergency. The FCS design is consistent with this SDC, which include multiple readouts and alarms for SFP temperature, water level, and area radiation monitors. Additionally, FCS maintains procedure AOP-36, Loss of Spent Fuel Pool Cooling, to guide the response in the event that cooling or level is lost in the SFP. The Control Room is also alerted by alarm when a SFP cooling pump is not running. This allows for prompt operation action prior to having an issue with cooling. SFP temperature indication in the Control Room is monitored from a point in the SFP cooling path on the outlet of the heat exchanger. Additionally, the component cooling water temperature through the heat exchanger is also monitored. Both of these indications will cause alarms in the control room on high temperature. Additionally, temperature indications from the 1013-, 1022-, and 1035-foot elevations of the SFP are displayed and recorded on the plant computer. These indications have high, high-high, and rate of change alarms. SFP water level is monitored each shift as part of surveillance testing using an installed level indication. The level indication includes an alarm in the control room for both high and low SFP level. This alarm will be changed to reflect the requirement of Emergency Plan limits. There is a field installed ruler type level indication mounted to the SFP liner and can be used to manually monitor the SFP level. In the event of a beyond design basis flooding event, additional level indication is available for installation in the SFP as driven through OCAG-2/3/4. FCS will continue to use the approved NRC EAL scheme, based on NEI 99-01, Development of Emergency Action Levels for Non-Passive Reactors, Revision 6. FCS will adopt to the Permanently Defueled EALs based on Appendix C of NEI 99-01. Based on the current EAL scheme a declaration of General Emergency would be based on radiation levels from a fuel handling accident. 4 Licensee determines that there are no drain paths in the SFP that could lower the pool level (by draining, suction, or pumping) more than 15 feet below the normal pool operating level and that licensee must initiate recovery using offsite sources. The normal pool operating level is 1035'-6". The SFP cooling system is normally supplied through an 8" pipe at 1034'-0". The SFP cooling system discharges through an 8" pipe. The discharge pipe enters the SFP at 1034'-0" and ends at 1031'-7" (a 90 degree elbow to direct flow downward). This discharge line is provided with a 1/2 inch hole to act as a vacuum breaker. The discharge line is also the normal borated makeup path for the SFP. The SFP cooling system has an additional lower suction point at an elevation of 1011'-4", which is more than 15 feet below the normal pool operating level, but above the top of the fuel assemblies, which are at an elevation of 1008"-6". The lower suction valve is locked closed and controlled closed. Additionally, FCS maintains an administrative requirement that the SFP be LIC-16-0109

Page 67 maintained at an elevation of 1033' to 1037'-9" at all times. This ensures compliance with Technical Specifications, maintaining greater than 23 feet of water above the top of the fuel. The gate connecting the SFP to the fuel transfer canal is designed such that the minimum possible water level in the SFP is 1009'-8.5". The gate is a taper design that is 7'4" wide at the top and tapers to 4'6" wide at the bottom. The gate is constructed of carbon steel with stainless steel plate. The lower one-third is filled with concrete to withstand hydrostatic forces. The gate is sealed using a rubber gasket at the gate-to-SFP liner interface. This design provides a passive seal (e.g., in comparison to the active seal of designs using inflatable bladders). The fuel transfer canal has two openings that are more than 15 feet below the normal pool operating level. These lower openings are only a credible drain path when the SFP gate is removed. The lowest entry point to the fuel transfer canal when the gate is removed is at the 1009'-8.5" elevation (i.e., cannot drain below this elevation). The first opening is the fuel transfer tube, where the opening centerline is at 1001'-6" and the bottom of the transfer tube is at 1000'. The transfer tube is isolated, except during refueling, by a flange on the reactor side and by a gate valve in the fuel transfer canal. The isolation valve is a 36 inch, double sliding stem gate valve, manually operated from the 1038' elevation of the spent fuel deck area. The second opening is the drain at the bottom of the fuel transfer canal, which is at 995'-6". This opening has a locked closed isolation valve that is controlled closed except during specific operations (e.g., transfer to waste, draining transfer canal). Both of these openings cannot drain below an elevation of 1009'-8.5" since that is the bottom of the SFP gate opening. FCS maintains procedures and guidelines in place to obtain offsite assistance if necessary for mitigation of events that result in significant loss of SFP inventory. These mitigating strategies were implemented as part of AOP-36 and are also included in B.5.b requirements. 5 Load Drop consequence analyses will be performed for facilities with nonsingle failure-proof systems. The analyses and any mitigative actions necessary to preclude catastrophic damage to the SFP that would lead to a rapid pool draining would be sufficient to demonstrate that there is high confidence in the facilities ability to withstand a heavy load drop. The FCS design is in alignment with this description. The heavy loads and crane usage around the SFP are controlled through GM-OI-HE-002, Auxiliary Building Crane HE-2 Normal Operation. Attachment 13 of this procedure summarizes the licensing basis for the Auxiliary Building crane being single failure-proof. FCS maintains a defense-in-depth approach to control heaving loads in the SFP area. The basis for FCS's defense-in-depth approach for the control of heavy loads in the SFP area consists of preventing load drops due to crane failure, rigging failure, or human error through a combination of the use of the single failure-proof crane and through compliance with the following guidelines from NUREG-0612. 1. Definition of safe load paths 2. Development of load handling procedures LIC-16-0109

Page 68 3. Periodic inspection and testing of cranes 4. Qualifications, training and specified conduct of operators 5. Special lifting devices should satisfy the guidelines of ANSI N14.6 6. Lifting devices that are not specially designed should be installed and used in accordance with the guidelines of ANSI B30.9

7. Design of cranes to ANSI B30.2 or CMAA-70 Rigging equipment meeting guideline Nos. 5 and 7 must be used to maintain single failure-proof status. The licensing basis with regard to these guidelines requires that off the shelf and specially designed rigging equipment meet one of the following requirements: 1. Provide redundancy or duality such that a single lift point failure will not result in uncontrolled lowering of the load; lift points must have a design factor of safety with respect to ultimate strength of five times the maximum load. The following is an example for meeting this requirement. Lifting a 10,000 lb. load requires two sets of rigging, each rated for at least 10,000 lbs. (with a 5:1 factor of safety). The total combined factor of safety would then be 10:1. or 2. A non-redundant or non-dual lift point system must have a design safety factor of ten times the maximum load. This can be met by using one set of rigging rated at 20,000 lbs. (with a 5:1 factor of safety) to lift a 10,000 lb. load. The total combined factor of safety would then be 10:1. Because the Auxiliary Building crane is single failure-proof, an accidental load drop is considered not to be a credible event such that condition 5.1.2(1) of NUREG-0612 is satisfied and analysis of cask drop accidents in accordance with condition 5.1.2(4) of NUREG-0612 is not required. 6 Each decommissioning plant will successfully complete the seismic checklist provided in Appendix 2B to this study [NUREG-1738]. If the checklist cannot be successfully completed, the decommissioning plant will perform a plant specific seismic risk assessment of the SFP and demonstrate that SFP seismically FCS conducted a seismic evaluation in response to a NRC request for information pursuant to 10 CFR 50.54(f) regarding Recommendation 2.1 of the NTTF Review of Insights from the Fukushima Dai-ichi Accident. The seismic evaluation included all structures including the SFP, and was prepared and submitted for NRC review. The OPPD submittal (LIC-14-0047) (Reference 15) documents the seismic evaluation in conformance with NTTF Recommendation 2.1 including the HCLPF values and the 1 x 10

-5 per year hazard level. The Staff review of the NTTF submittal, specifically for the SFP Evaluation associated with the reevaluated seismic hazard implementing NTTF Recommendation 2.1 (CAC No. MF3735) is documented in NRC-16-0068 (ML16182A361) (Reference 16). The NRC staff concluded that the assessment was LIC-16-0109

Page 69 induced structural failure and rapid loss of inventory is less than the generic bounding estimates provided in this

study (<1 x10 -5 per year including non-seismic events). performed consistent with the NRC-endorsed (ML15350A158) (Reference 17) SFP Evaluation Guidance Report (Reference 18) and provided sufficient information, including the SFP integrity evaluation, to meet the SFP Evaluation Guidance (Item 9 in Enclosure 1 of the NRC's 50.54(f) letter), thus supporting SDA No. 6 of NUREG-1738. 7 Licensees will maintain a program to provide surveillance and monitoring of Boraflex in high-density spent fuel racks until such time as spent fuel is no longer stored in these high-density racks. The FCS spent fuel racks utilize Boral rather than Boraflex as a neutron absorbing material. There are two regions or types of racks in the SFP that both contain Boral as described in USAR 9.5. The Boral is attached as panels between each storage cell. The panels are protected with a stainless steel sheath. The technical specifications describe the surveillance test requirements, which requires poison sample coupons to be tested for dimensional change, weight, neutron attenuation change, and specific gravity change. This is required 1, 2, 4, 7, and 10 years after installation, and every 5 years thereafter. The purpose of the coupon sample program is to ensure that the required amount of boron remains in the neutron absorber material throughout the life of the racks. These coupon samples are sent out for analysis to an independent firm whose results are reviewed and accepted by FCS. LIC-16-0109

Page 70 10 CFR 50.12 states that the Commission may, upon application by any interested person or upon its own initiative, grant exemptions from the requirements of the regulations of 10 CFR Part 50 which are authorized by law, will not present an undue risk to the public health and safety, and are consistent with the common defense and security. 10 CFR 50.12 also states that the Commission will not consider granting an exemption unless special circumstances are present. As discussed below, this request for exemptions satisfies the provisions of Section 50.12.

10 CFR 50.12 allows the NRC to grant exemptions from the requirements of 10 CFR Part 50. The proposed exemptions would not result in a violation of the Atomic Energy Act of 1954, as amended, or the Commission's regulations. Therefore, the exemptions are authorized by law.

The underlying purpose of 10 CFR 50.47(b); 10 CFR 50.47(c)(2); and 10 CFR Part 50, Appendix E, is to ensure that there is reasonable assurance that adequate protective measures can and will be taken in the event of a radiological emergency, to establish Plume Exposure and Ingestion Pathway EPZs for nuclear power plants, and to ensure that licensees maintain effective offsite and

onsite emergency plans. As discussed in this request, FCS performed an analysis indicating that within 10 days after shutdown, the radiological consequences of the postulated accident will not exceed the limits of the EPA PAGs at the EAB. In addition, FCS has developed an analysis for beyond design basis events related to the SFP which show that 530 days (1 year, 165 days) after permanent cessation of power operations, the analyzed event is either not credible, is capable of being mitigated, or the radiological consequences of the event will not ex ceed the limits of the EPA PAGs at the EAB.

Additionally, the offsite and Control Room radiological impacts of a postulated complete loss of SFP water were assessed. It was determined that the gamma radiation dose rate at the EAB would be limited to small fractions of the EPA PAG exposure levels and the dose rate in the Control Room will be below 2.32 x 10 -3 mRem/hr, which is less than 15 mRem/hr. For these reasons, offsite emergency response plans will no longer be needed for protection of the

public beyond the EAB 530 days after permanent cessation of power operations. Based on the reduced consequences of radiological events possible at FCS in the permanently defueled condition, the scope of the onsite emergency preparedness organization and corresponding offsite requirements in the emergency plan may be accordingly reduced without an undue risk to the public health and safety.

Therefore, the underlying purpose of the regulations will continue to be met. Because the underlying purpose of the rules will continue to be met, the exemptions will not present an undue risk to the public health and safety.

LIC-16-0109

Page 71 The reduced consequences of radiological events that will remain possible at FCS when it is in the permanently defueled condition allows for a corresponding reduction in the scope of the onsite emergency preparedness organization and associated reduction of requirements in the emergency plan. These reductions will not adversely affect FCS's ability to physically secure the site or protect special nuclear material. Physical security measures at FCS are not affected by the requested exemptions. Therefore, the proposed exemptions are consistent with the common defense and security. Pursuant to 10 CFR 50.12(a)(2), the NRC will not consider granting an exemption to its regulations unless special circumstances are present. OPPD has determined that special circumstances are present as discussed below. Special circumstances will exist at FCS because the plant will be permanently shut down and defueled and the radiological source term at the site will be reduced from that associated with reactor power operation. With the reactor permanently shut down and defueled, the accidents postulated to occur during reactor operation will no longer be possible. In particular, the potential for a release of a large radiological source term to the environment from the high pressures and temperatures associated with reactor operation will no longer exist.

The underlying purpose of 10 CFR 50.47(b), 10 CFR 50.47(c)(2), and 10 CFR Part 50, Appendix E is to ensure that there is reasonable assurance that adequate protective measures can and will be taken in the event of a radiological emergency, to establish Plume Exposure and Ingestion Pathway EPZs for nuclear power plants, and to ensure that licensees maintain effective offsite and

onsite emergency plans. The standards and requirements in 10 CFR 50.47(b); 10 CFR 50.47(c)(2); and 10 CFR Part 50, Appendix E, were developed taking into consideration the risks associated with operation of a nuclear power reactor at its licensed full power level. These risks include the potential for a reactor accident with offsite radiological dose consequences. The radiological consequences of the postulated accident that will remain possible at FCS upon permanent shutdown of power operations are substantially lower than those at an operating plant. The upper bounds of the analyzed dose consequences limits the highest attainable emergency class to the Alert level. In addition, because of the reduced consequences of radiological events that will still be possible at the site, the scope of the onsite emergency preparedness organization may be reduced accordingly. Thus, the underlying purpose of the regulations will not be adversely affected by eliminating offsite emergency planning activities or reducing the scope of onsite emergency planning as described in this request.

LIC-16-0109

Page 72 Radiological analysis indicates that within 10 days after shutdown, the radiological consequences of the postulated accident that will remain possible at FCS upon permanent removal of fuel from the reactor will not exceed the limits of the EPA PAGs at the EAB. In addition, an analysis has been developed for beyond design basis events related to the SFP which show that 530 days (1 year, 165 days) after permanent cessation of power operations, the analyzed event is either not credible, is capable of being mitigated, or the radiological consequences of the event will not exceed the limits of the EPA PAGs at the EAB. Therefore, application of all of the standards and requirements in 10 CFR 50.47(b); 10 CFR 50.47(c)(2); and 10 CFR Part 50, Appendix E are not necessary to achieve the underlying purpose of those rules.

Because the underlying purposes of the rules would continue to be achieved even with FCS being permitted to reduce the scope of emergency preparedness requirements consistent with placing the facility in the permanently defueled condition, application of the rules is not necessary to achieve the underlying purpose, and the special circumstances are present as defined in

10 CFR 50.12(a)(2)(ii).

Application of all of the standards and requirements in 10 CFR 50.47(b); 10 CFR 50.47(c)(2); and 10 CFR Part 50, Appendix E is not necessary for adequate emergency response capability and is excessive for a permanently shut down and defueled facility. Application of all of these standards and requirements would result in undue costs being incurred for the maintenance of an ERO in excess of that actually needed to respond to the diminished scope of credible events. Other licensed sites similarly situated, such as Entergy Nuclear Operation, Inc.'s (ENO) Vermont Yankee Nuclear Power Station (VY), Southern California Edison Company's San Onofre Nuclear Generating Station (SONGS), Duke Energy Florida, Inc.'s Crystal River Unit 3 Nuclear Generating

Station (CR3), and Dominion Energy Kewaunee, Inc.'s Kewaunee Power Station (KPS), have recently been granted similar exemptions.

Therefore, compliance with the rule would result in an undue hardship or other costs that are significantly in excess of those contemplated when the regulation was adopted, or that are significantly in excess of those incurred by others similarly situated. The special circumstances required by 10 CFR 50.12(a)(2)(iii) exist.

The plant will be permanently shut down and defueled and the radiological source term at the site will be reduced from that associated with reactor power operation. With the reactor permanently shut down and defueled, the postulated accidents that could occur during reactor operation will no longer be possible. In particular, the potential for a release of a large radiological source term to the environment from the high pressures and temperatures associated with reactor operation will no longer exist.

LIC-16-0109

Page 73 The proposed exemptions would allow FCS to revise the onsite emergency plan to correspond to the reduced scope of remaining accidents and events. As such, the emergency plan would no longer need to address response actions for events that would no longer be possible. The revised emergency plan would thereby enhance the ability of the ERO to respond to those scenarios that remain credible because emergency preparedness training and drills would focus only on applicable activities. Elimination of requirements for classification of EALs for events that were no longer possible would enhance the ability of the ERO to correctly classify those events that remain credible. As the proposed exemptions will enhance the ability of the organization to respond to credible events, a resultant benefit to the public health and safety is realized.

Therefore, because granting the exemptions would result in benefit to the public health and safety and would not result in a decrease in safety, the special circumstances required by

10 CFR 50.12(a)(2)(iv) exist. The exemption requests for 10 CFR 50.47(b); 10 CFR 50.47(c)(2); and 10 CFR Part 50, Appendix E requirements are consistent with exemptions on the same emergency planning requirements that recently have been issued by the NRC for other nuclear power reactor facilities beginning decommissioning. Specifically, the NRC granted similar exemptions to ENO for VY (Reference 25); to Southern California Edison Company for SONGS, Units 1, 2, and 3 (Reference 26); to Duke Energy Florida, Inc. for CR3 (Reference 27); and to Dominion Energy Kewaunee, Inc. for KPS (Reference 28). Similar to the current request, these precedents each resulted in exemptions from certain emergency planning requirements in 10 CFR 50.47(b); 10 CFR 50.47(c)(2); and 10 CFR Part 50, Appendix E, related to the elimination of offsite radiological emergency plans and reduction in the scope of the onsite emergency planning activities. For the same reasons that the NRC recently issued these exemptions, OPPD seeks approval of the enclosed proposed exemption requests.

The proposed exemptions meet the eligibility criterion for categorical exclusion set forth in 10 CFR 51.22(c)(25), because the proposed exemptions involve: (i) no significant hazards consideration; (ii) no significant change in the types or significant increase in the amounts of any effluents that may be released offsite; (iii) no significant increase in individual or cumulative public or occupational radiation exposure; (iv) no significant construction impact; (v) no significant increase in the potential for or consequences from radiological accidents; and (vi) requirements of an administrative, managerial, or organizational nature. Therefore, pursuant to 10 CFR 51.22(b), no environmental impact statement or environmental assessment need be prepared in connection with the proposed exemptions.

Omaha Public Power District (OPPD) has evaluated the proposed exemptions to determine whether or not a significant hazards consideration is involved by focusing on the three standards set forth in 10 CFR 50.92 as discussed below:

LIC-16-0109

Page 74 1. Does the proposed exemption involve a significant increase in the probability or consequences of an accident previously evaluated? The proposed exemptions have no effect on structures, systems, and components (SSCs) and no effect on the capability of any plant SSC to perform its design function. The proposed exemptions would not increase the likelihood of the malfunction of any plant SSC.

When the exemptions become effective, there will be no credible events that would result in doses to the public beyond the Exclusion Area Boundary (EAB) that would exceed the Environmental Protection A gency (EPA) Protective Action Guides (PAGs). The probability of occurrence of previously evaluated accidents is not increased, because most previously analyzed accidents will no longer be able to occur and the probability and consequences of the remaining postulated accident, a fuel handling accident (FHA), is unaffected by the proposed exemptions. Therefore, the proposed exemptions do not involve a significant increase in the probability or consequences of an accident previously evaluated.

2. Do the proposed exemptions create the possibility of a new or different kind of accident from any accident previously evaluated?

The proposed exemptions do not involve a physical alteration of the plant. No new or different type of equipment will be installed and there are no physical modifications to existing equipment associated with the proposed exemptions. Similarly, the proposed exemptions will not physically change any SSCs involved in the mitigation of any accidents. Thus, no new initiators or precursors of a new or different kind of accident are created. Furthermore, the proposed exemptions does not create the possibility of a new accident as a result of new failure modes associated with any equipment or personnel failures. No changes are being made to parameters within which the plant is normally operated, or in the set points which initiate protective or mitigative actions, and no new failure modes are being

introduced. Therefore, the proposed exemptions do not create the possibility of a new or different kind of accident from any accident previously evaluated.

3. Do the proposed exemptions involve a significant reduction in a margin of safety?

The proposed exemptions do not alter the design basis or any safety limits for the plant. The proposed exemptions do not impact station operation or any plant SSC that is relied upon for accident mitigation.

Therefore, the proposed exemptions do not involve a significant reduction in a margin of safety. Based on the above, OPPD concludes that the proposed exemptions present no significant hazards consideration, and, accordingly, a finding of "no significant hazards consideration" is justified.

LIC-16-0109

Page 75 There are no expected changes in the types, characteristics, or quantities of effluents discharged to the environment associated with the proposed exemptions. There are no materials or chemicals introduced into the plant that could affect the characteristics or types of effluents released offsite. In addition, the method of operation of waste processing

systems will not be affected by the exemptions. The proposed exemptions will not result in changes to the design basis requirements of SSCs that function to limit or monitor the release of effluents. The SSCs associated with limiting the release of effluents will continue to be able to perform their functions. Therefore, the proposed exemptions will not result in changes to the types or significant increases in the amount of any effluents that may be released offsite. The exemptions will result in no expected increases in individual or cumulative occupational radiation exposure on either the workforce or the public. There are no expected changes in normal occupational doses. Likewise, the dose of the postulated accident is not impacted

by the proposed exemptions. No construction activities are associated with the proposed exemptions.

See the no significant hazards considerations discussion in Item (i)(1) above.

The proposed exemptions will form the basis for a reduction in the size of the FCS ERO commensurate with the reduction in consequences of radiological events that will be possible at FCS when the facility is in the permanently defueled condition. They also will modify the requirements for emergency planning. Therefore, the exemptions address requirements of an administrative, managerial, or organizational nature.

This calculation satisfies the NRC expectation set forth in Item 2 of Section 5.0 of the Interim Staff Guidance for emergency planning exemption requests (Ref. 4.1) which states that an adiabatic heat-up analysis be used to determine when a minimum of 10 hours is available from the time cooling is lost before the cladding temperature reaches 900°C. This analysis conservatively assumes that there is no radiative or air cooling of the fuel assemblies: the flow paths that would provide natural circulation cooling are assumed to be blocked and no credit is taken for radiation or conduction to adjacent assemblies or spent fuel pool racks. Omaha Public Power District Fort Calhoun Station 2.0 Inputs 2.1 Maximum Fuel Cladding Temperature S&L Calculation 2016-10694 (FC08104) Revision 0 PageS Item 2 of Section 5.0 of the Interim Staff Guidance for emergency planning exemption requests (Ref. 4.1) states that an adiabatic heat-up analysis be used to determine when a minimum of 1 0 hours is available from the time cooling is lost before the cladding temperature reaches 900°C. Therefore, 900°C is the maximum fuel cladding temperature investigated in this calculation. This is the temperature where "runaway oxidation" is expected to occur per NUREG-1738 (Ref. 4.6, p. 3-7). 2.2 Fuel Cladding Properties The fuel cladding material is M5Ž Zirconium alloy (Ref. 4.3). The density to be used for the cladding is 6.55 g/cm 3 (Ref. 4.3) or 408.9 lbm/ft 3 [=6.55 * (30.48 cm/ft)3 I 453.59 gllbm]. The specific heat of M5Ž Zirconium alloy increases as temperature increases over most of the temperature range of interest (Table 3 of Ref. 4.3). The mass based specific heat below is computed by dividing the provided volumetric heat capacity by the density. Table 2-1: Fuel Cladding Heat Capacity Temperature Volumetric Heat Capacity Mass Based Heat Capacity OF oc Btu/ft 3-°F Btu/lbm-°F 31.7 -0.2 27.23 0.0666 1520.3 826.8 39.98 0.0978 1592.3 866.8 88.69 0.2169 1790.3 976.8 32.57 0.0797 2.3 Spent Fuel Pool Temperature I Spent Fuel Initial Temperature The spent fuel pool maximum normal temperature is 140°F (Ref. 4.3). This temperature is appropriate to use as the initial cladding temperature for this analysis. In the generic analyses in both SECY-99-168 (Ref. 4.4) and NUREG-1738 (Ref. 4.6, pg. 2-2), the starting water/fuel assembly temperature was set at 30°C (86°F). Both documents state that the analysis starts at the time of fuel uncovery. Using 140°F as the starting temperature of the analysis is conservative compared to the initial temperature used in NUREG-1738 and SECY-99-168 because more heat energy is required to heat the assembly from 86°F to 900°C than is required to heat the assembly from 140°F to 900°C. Therefore, the decay heat required for a given heat up time (e.g. 10 hrs) will be reached earlier after shutdown for lower initial temperatures. Since the result of this analysis is a time after shutdown and a greater time is conservative, use of a higher initial temperature is conservative. Furthermore, using the spent fuel pool maximum normal temperature for the initial temperature of the spent fuel is a source of conservatism: as the decay time increases Omaha Public Power District Fort Calhoun Station S&L Calculation 2016-10694 {FC08104) Revision 0 Page9 {i.e. as the plant has been shutdown longer) the fuel heat generation rate will be lower and the maximum spent fuel pool temperature would likely be lower. 2.4 Fuel Assembly Geometry (Ref. 4.3) T bl 2 2 F I A a e -: ue ssem bl G IY t eometry Fuel Type 14x14 Combustion Engineering Fuel Pellet Diameter 0.3805 inches Inner Diameter of Cladding 0.387 inches Outer Diameter of Cladding 0.440 inches Number of Full Length Rods per Assembly 176 Number of Partial Length Rods per Assembly 0 Active Fuel Length of Full Length Rods 129.3 inches Number of Other Tubes in Assembly 4 guide tubes and 1 instrument tube Inner Diameter of Guide & Instrument Tubes 1.035 inches Outer Diameter of Guide & Instrument Tubes 1.115 inches In addition, Reference 4.7(b) shows that the fuel rod pitch {center to center distance) is 0.580 inches, resulting in an orthogonal spacing of 0.140 inches [=0.580-0.440] between fuel rods (distance between cladding). Based on Figure 3.1 of Reference 4.9, Cycle 28 (the final fuel cycle) consists of fuel from batches DO, EE, FF, and GG. The fuel assemblies corresponding to these batches are htp_24, htp_25, htp_26, and htp_27, respectively, based on p. 119 in Attachment 4 of Reference 4.1 0. The guide tube material for each of these fuel assembly types is provided as parameter assy_gt_matl on pp. 67, 79, 91, and 102, respectively, of Attachment 4 of Reference 4.10. Similarly, the instrument tube material for each of these fuel assembly types is provided as parameter assy_it_matl on pp. 68, 80, 91, and 103, respectively, of Attachment 4 of Reference 4.1 0. The above information is used to determine that the guide and instrument tube material is M5Ž Zirconium alloy. 2.5 Fuel Properties The fuel is uranium dioxide, U0 2 {Ref. 4.3). The fuel density is equal to 96o/o of the theoretical density of 10.96 g/cm 3 {Ref. 4.3). Thus, the fuel density is 10.5216 g/cm 3 [=0.96

• 10.96] or 656.8 lbm/ft 3 [=10.5216
• {30.48 cm/ft)3 I 453.59 g/lbm]. The specific heat of uranium dioxide fuel increases as temperature increases over the temperature range of interest {Table 2 of Ref. 4.3). The mass based specific heat below is computed by dividing the provided volumetric heat capacity by the fuel density.

• (30.48 cm/ft)3 /453.59 g/lbm]. The fuel stack density is slightly less dense than the fuel since it accounts for the fact that fuel pellets are not perfectly cylindrical since they have dished ends, chamfered edges, and an outward land taper (OL T). The fuel stack density is 98.6% of the fuel density since the volume reduction (relative to a right circular cylinder) due to the aforementioned geometric features is 1.4% (Table 3.3 and Section 5.1.2 of Ref. 4.9). When computing the mass of fuel, the stack density should be used with the pellet stack volume assuming a right circular cylinder.

It is recognized that Table 3.3 of Reference

4.9 lists

dish, OLT, and chamfer volumes of both 1.2% and 1.4o/o. These volumes are the reductions in pellet stack volume relative to a right circular cylinder. The 1.2°Al volume is only applicable to blanket pellets, while the 1.4o/o volume is applicable to enriched pellets. Blanket pellets are those at the top and bottom of the fuel rods. Since the overwhelming majority of pellets are enriched pellets, 1.4% is the appropriate volume to use. Furthermore, use of 1.4% is conservative as it results in less fuel mass and hence a faster heat-up time.

4.5 states

that the maximum decay heat load from a single assembly occurs for Fuel Assembly DD07. The table below shows the maximum fuel assembly heat generation rate for several different times after shutdown. Table 2-4: Heat Generated by Highest Heat Load Fuel Assembly (0007) Cooling Time (years) Cooling Time (months) Decay Heat (watts) 1.0 12 5043 1.0833 13 4764 --1.167 14 4515 "-Y 1.25 15 4291 1.33 16 4086 1.4167 17 3898 1.5 18 3726 2.0 24 2921 2.5 30 2380 3.0 36 2002 The reactor contains 133 fuel assemblies (Ref. 4.7(a)) and has a 100o/o reactor power level of 1500 Mwt (Ref. 4.8). Therefore, the average heat generation for an assembly at full power in the reactor is 11.3 megawatts [=1500/133]. The heat loads in the table above are on the order of 0.04o/o to 0.02o/o of the peak reactor power. NUREG-1738 (Ref. 4.6) mentions that additional heat load due to oxidation of the cladding may exist at temperatures less than 900°C, although it is not a significant heat source below 600°C (p. A1A-5 of NUREG-1738). However, the oxidation heat load is not included in the adiabatic analysis in NUREG-1738. For the purposes of comparing the adiabatic heat-up results for the Fort Calhoun fuel to the generic results in NUREG-1738, no additional oxidation heat load is applied herein. Exclusion of oxidation heat loads is consistent with the Staff guidance for adiabatic spent fuel heat-up (Section 4.0 of Ref. 4.1 ). The Staff recognized the exclusion of oxidation as non-conservative, but stated that the overall adiabatic heat-up analysis reasonably represents conditions that may occur in the event of an SFP accident involving the loss of water inventory. The Staff conclusion was based on weighing the conservatisms of the adiabatic heat-up analysis methodology with the non-conservatisms. Omaha Public Power District Fort Calhoun Station 3.0 Assumptions S&L Calculation 2016-10694 (FC08104) Revision 0 Page 12 3.1 The heat-up time does not credit the drain down time of the pool. This is conservative because no credit is taken for the thermal capacitance of the water. 3.2 It is assumed that the properties for uranium dioxide fuel adequately represent all metal oxides in spent fuel, which contains uranium as well as measureable amounts of other elements such as neptunium, plutonium, americium, and curium (Tables 5.6 and 5. 7 of Ref. 4.11). Based on Tables 5.4 through 5.7 of Reference 4.11, the mass of uranium dioxide at discharge and 10 years after discharge is 93-95% of the total initial mass of fuel. Given that some mass is converted to energy during the fuel cycle, it can be concluded that the mass of uranium dioxide in spent fuel is greater than 93% of the total spent fuel mass. Tables 5.6 and 5.7 present the results of ORIGEN runs for spent fuel with 3.2o/o and 4.2%, uranium 235 enrichment, respectively. These enrichments are similar to Fort Calhoun which utilizes fuel with enrichments ranging from 3.3 to 4.5°/o uranium 235 (pp. 48 and 108 of Ref. 4.9).

Zirconium alloy is in the cladding and the guide/instrument tubes. The zirconium and the uranium dioxide are modeled as heating up at the same rate since: 1) the fuel pellets and zirconium alloy are immediately adjacent to each other, 2) the heat is generated throughout the assembly, 3) the transient is relatively slow, and 4) the materials have high thermal conductivities. Therefore, the will be the same for both materials. Where: Xu signifies the property is for yranium dioxide Xz signifies the property is for alloy Equation 6-2 Given that the volume of uranium dioxide computed below is based on a right circular cylinder, the appropriate uranium dioxide density to use is the fuel stack density.

The heat-up time is calculated for discrete temperature increments of 1 00°F or less in order to more accurately model the heat capacity. For each temperature increment, the minimum specific heats of zirconium alloy and uranium dioxide are used. Minimizing the specific Omaha Public Power District Fort Calhoun Station S&L Calculation 2016-10694 (FC08104) Revision 0 Page 16 heat is conservative as it results in a faster heat-up. The total heat-up time is then the sum of the heat-up times for the increments up to the temperature of interest (900°C). The volume of uranium dioxide is given below. V cyl = (1t . _DP_2 ) . Nh .

The length of the cladding and tubes that is heated is conservatively modeled as being the same as the heated length of uranium dioxide. In reality, the cladding and guide/instrument tubes are longer than the length of the uranium dioxide pellets (i.e. the heated length of the fuel is less than the total length of the assembly). Thus, the actual mass of zirconium in a fuel assembly is greater than that which is modeled. Modeling less zirconium results in faster heat-up times, which are conservative. V = (1t .

Omaha Public Power District Fort Calhoun Station S&L Calculation 2016-10694 (FC08104) Revision 0 Page 17 Temperatures in the fuel assembly are modeled as uniform before and during the event since: 1) the heat generation rate is relatively uniform and low (see Input 2.6), 2) the diameter of the fuel rods is small, and 3) the spacing between rods is small (0.14 inches per Input 2.4). The heat-up time is calculated as a function of the decay time after reactor shutdown.

6.2 Acceptance

Criteria There are no specific acceptance criteria for this analysis. However, the goal is to determine the decay time after shutdown at which it takes 1 0 hours for the fuel to heat up to 900°C. This supports the analysis requirement set forth in Item 2 of Section 5.0 of the Interim Staff Guidance for emergency planning exemption requests (Ref. 4.1 ), repeated below. Complete loss of SFP water inventory with no heat loss (adiabatic heatup) demonstrating a minimum of 10 hours is available before any fuel cladding temperature reaches 900 degrees Celsius from the time all cooling is lost (Demonstrates sufficient time to mitigate events that could lead to a zirconium cladding fire); ... Reference 4.1 is consistent with SECY-99-168 (Ref. 4.4) which suggests that "10 hours [is] sufficient time to take mitigative actions." SECY-99-168 performed a generic analysis that found that for PWRs, 2.5 years is expected to be the decay time needed to reach a 10 hour heat-up time from 30°C to 900°C while NUREG-1738 shows that a 10 hour adiabatic heat up time from 30°C to 900°C for a PWR would occur at less than 2 years (Ref. 4.6, Fig. 2.2). The results of this analysis are compared to the generic analyses.

1) at various times after shutdown are shown below. Table 8-1 : Results Cooling Time Cooling Time Heat-Up Time to 900°C (1652°F) (Months) (Years) (hours) 12 1.0 7.6 13 1.0833 8.0 14 1.167 8.5 15 1.25 8.9 16 1.33 9.4 17 1.4167 9.8 18 1.5 10.3 24 2.0 13.1 30 2.5 16.1 36 3.0 19.1 By interpolating, the heat-up time to 900°C is at least 10 hours at a decay time of 1.453 years (1 year, 165 days) after shutdown.

This duration is based on 365 days per year. As stated in Section 6.2, SECY 168 performed a generic analysis that found that for PWRs, 2.5 years is expected to be the decay time needed to reach a 1 0 hour heat-up time from 30°C to 900°C. NUREG-1738 shows that a 10 hour heat up time to 900°C for a PWR would occur at less than 2 years (Ref. 4.6, Fig. 2.2). The results calculated here are consistent with the NUREG-1738 analysis. Figure 8-1 shows the heat-up time to 900°C as a function of decay time.

• Convective heat transfer (air cooling) is not credited.
• No heat transfer (convection, radiation, or conduction) from the hottest assembly to adjacent colder assemblies is credited.
• Metal heat capacitance for the fuel rods and guide/instrument tubes beyond the heated length, spacer grids, the upper and lower end fittings, and channel walls in the fuel assembly is ignored. Water thermal capacitance during drain down is ignored.

Dear Mr. Peterson ,

Calculation FC08514 was completed to generate decay heat data as a function of time for the assembly with the highest decay hea t load In the Fort Calhoun Station spent fuel pool after permanent cessation of operat i ons. The calculation has determined that the hottest assem.bly in the spent fuel pool is Assembly DD07. The decay heat In Watts from 1 year after shutdown to 3 years after shutdown is shown below from Reference 1, p.44. The decay heat data presented above is su i table for use by Sargent & Lundy to perform calculations for the adiabatic heatup of the highest decay heat spent fuel assembly. Please contact me with any questions or if you require any further information.

CALCULATION SHEET FC08513 Revision 0 Page 7 of269 1.0 Purpose The purpose for this calculation will be to show that the maximum dose at the EAB will be well below the acceptance criterion, which is taken to be based upon EPA Protective Action Guidelines (PAGs, Reference 21). The MCNP calculation determines the dose rate as a function of time following a full drain down of the spent fuel pool. This calculation does not determine a dose rate during the drain-down and utilizes a single time point which is used in calculating the time varying dose. The time of the event is estimated to be 18 months after December 1, 2016, i.e. June 1, 2018. The dose rate will be calculated using the code MCNP6.1 (References 1-4). The dose rates to be calculated were the direct and scattered gamma and neutron radiation as a result of a complete drain down of water from the Fort Calhoun Station (FCS) spent fuel pool (SFP). The complete drain down of water in the SFP is considered a beyond design basis event as it is not part of the FCS Updated Safety Analysis Report (USAR). 1 .1 Objective Determine the gamma and neutron an average dose rate to the plant staff in the Control Room (CR) and to the public at the Exclusion Area Boundary (EAB). Fort Calhoun Station CALCULATION SHEET FC08513 Revision 0 Page 8 of 269 2.0 Inputs This calculation utilizes various drawings, references and assumptions to develop an MCNP model to determine dose rates at the EAB and CR. These inputs are show in the calculation where the input is referenced and utilized.

Fort Calhoun Station CALCULATION SHEET FC08513 Revision 0 Page 13 of 269 4.0 Assumptions

1. All structures are constructed of Ordinary Concrete.

Basis: Ordinary Concrete (Reference 5, Material 95 Concrete, Ordinary (NBS 03)) is a generic concrete of granite/sand aggregate and the most commonly available cement. In most nuclear power plants, the grade of concrete is specified during construction. With varying concretes densities ranging from 2.18 to 5.56 grams/cm 3 depending on application (Reference 5). The FCS contract 759 (Reference

6) specified a minimum of 145 lbs/ft 3 for type A and B concretes (equivalent to 2.322 grams/cm 3) and 224 lbs/ft 3 for type C concrete (equivalent to 3.588 grams/cm 3). Since most of the construction utilized Type A and B concretes and the Compendium of Material Composition Data for Radiation Transport Modeling has ordinary concretes with varying densities, the 2.35 grams/cm 3 was chosen as it has a similar density to the Type A and B concrete specifications.

2. Any volume not specifically specified as concrete, steel or fuel mixture was defined as dry air. Basis: Utilizing air without moisture simplifies the problem , additionally the scope of the evaluation is the SFP is completely drained. All water is removed. 3. The railroad siding rollup door (1 004-1A) a rolling door of overlapping carbon steel design was modeled as single sheet of carbon steel. (Carbon Steel is used as the drawing title, Reference 14.60 is " STEEL ROLLING DOORS-RAILROAD SIDING FOR AUXILIARY BUILDING")

Basis: Due to the design of the door is overlapping carbon steel design. To calculate the percent of overlap is excessive detail for this type of model, and carbon steel is used since stainless steel would have been too expensive. This approach allows for more transmission of particles though door , thus the calculation will calculate a higher dose rate. 4. The railroad siding vertical lift door (1 004-1 C) was modeled similarly to the design of the door without utilizing the internal structural steel within the door or overlapping the panels. Basis: Due to the design of the door, The Polyisocyanurate insulation wrapped by the 14-gauge carbon steel simplifies the model. This approach also allows for more transmission of particles though door, thus the calculation will calculate a slightly higher dose estimate.

5. The reinforcing steel rebar in the concrete walls was not modeled due to the specific details that are difficult and excessive detail to model. Basis: The steel of the rebar is a more effective photon reflector/scatterer given its relatively high density compared to concrete.

The lack of rebar allows for more transmission of particles though walls of the auxiliary building and spent fuel area, thus the calculation will calculate a slightly higher dose estimate. Fort Calhoun Station CALCULATION SHEET FC08513 Revision 0 Page 14 of 269 6. The equipment in the affected rooms and hallways was disregarded in terms of shielding or scattering. Basis: This is conservative due to the materials would scatter/absorb particles (photons/ neutrons) and reduce the particle's effective energy, thus reduce dose from that particle. The affected buildings and hallways contain significant amounts of equipment. For example, room 69 contains: the various tanks storing water, component cooling water pumps and piping , as well as ventilation equipment. Equipment like this occupies space and provides additional scattering of the source photons/neutrons.

7. Modeling the auxiliary building and control room floors and walls was simplified by excluding the 2.5 feet concrete beams. Basis: By averaging these beams into the thickness of the floors and walls would increase the thickness and potentially decrease the dose. Incorporating the beams changes the scattering similarly to ignoring the equipment within the structures.

8. Only the areas adjacent to SFP at the 1 025' elevation of the auxiliary building was modeled , eliminating room 68 (the cask decontamination room). Basis: The remaining concrete structures below this level have a considerable amount of reinforced concrete and will have little impact to particles transporting through the exterior walls of the auxiliary building and to the control room. 9. The control operators occupy the control room twenty-four (24) hours a day, seven (7) days a week. (720 hours). Basis: Per current plant Technical Specification Table 5.2-1, " MINIMUM SHIFT CREW COMPOSITION," at least one of these individuals (or the second senior licensed operator, if both senior licensed operators are in the control room) must be present at the controls at all times. This consistent with NUREG-0737, Reference

22. 10. No axial or radial peaking factors are applied in developing the source, since this is a homogenized source term. Basis: The source term represents the spent fuel as a homogenized volume with each plane of the source representing a planar source with no self-shielding.

11. The Polyisocyanurate foam (PNNL-15870 material249 page 240 of 357) is an equivalent replacement for the Trymar 9501. Basis: OPPD Drawing G-576 shows Trymar 9501 as the insulation component for door 1004-1A. The DOW Chemical MSDS shows Trymar 9501 as a "POLYMERIZED POLYURETHANE MODIFIED POLYISOCYANURATE RIGID CELLULAR PLASTIC."

Fort Calhoun Station CALCULATION SHEET FC08513 Revision 0 Page 15 of 269 Since Trymar 9501 is not a commonly known material, research shows the following from the DOW MSDS sheet (Trymer): DOW CHEMICAL CO--TRYMER 9501-4 RIGID FOAM INSULATION, 02837 --9320-00N056603

12. This calculation assumes (a) no cladding failure during or after the drain down and (b) any existing cladding breaches (fuel pins with holes identified prior to Cycle 21) have released the gap activity or decayed significantly to impact overall radiation dose. Basis: (a) Spent fuel pool (SFP) accidents involving a sustained loss of coolant have the potential for leading to significant fuel heat up and resultant release of fission products to the environment.

This heatup is precluded because the fuel in the SFP is assumed to be beyond the point of heating up enough the fuel clad temperature will not exceed 900C for 1 0-hours after loss of SFP inventory, and; (b) Any fuel that has cladding breaches (i.e. from grid to rod fretting, etc.) has released radionuclides from the gap during storage in the pool water over the years, and was subsequently filtered through the SFP demineralizer and filtration system, along with pool skimmers. Cycle 20 (September 2003) was the last operating cycle with known fuel failures. This assumption maximizes the direct exposure from shine and bound the site-boundary and control room dose rate from direct shine. Fort Calhoun Station CALCULATION SHEET FC08513 Revision 0 Page 16 of 269 5.0 Method of Analysis and Acceptance Criteria 5.1 Method of Analysis MCNP6, "Monte Carlo N-Particle Transport Code," a radiation transport computer code, was utilized to determine dose rates from direct and scattered radiation at Fort Calhoun Station from spent fuel assemblies within the spent fuel pool following a complete loss of SFP water. This calculation does not determine airborne immersion or inhalation doses due to releases of radioactive material from the spent fuel assemblies following drain down of the SFP. Gamma and neutron cases are utilized to determine "shine" dose rates. A complete MCNP model was developed to evaluate specifically the FCS pool, auxiliary building, control room and containment. The simplified model assumes the main structures of the facility are present ignoring plant components such as piping, valves, pumps, ventilation equipment and sub-structures like electrical panels and internal non-structural walls. The MCNP model developed used existing FCS fuel information that was derived for the Extended Power Uprate (EPU) calculations (Reference

8) in terms of pool geometry and fuel modeling to expedite and simplify the process. EPU operating parameters were not utilized in this analysis.

Because the fuel cladding is assumed intact, at any point after 18-months post shutdown, the dominant noble gas in the source term within the fuel is Kr-85. Because Kr-85 is a noble gas, no shine from ground will be included, because the fuel cladding remains intact. The FCS model was developed to include various dose point tallies and detectors inside the control room, in and around the SFP area and outside of the buildings. Simplification of geometry was utilized when excessive details could not be modeled and did not reduce the expected attenuation before radiation would exit the auxiliary building. A homogenized fuel source was used which includes the 944 fuel assemblies to be stored in the FCS spent fuel pool after final operation of the Cycle 28. In addition to the fuel, the homogenized source incorporates the stainless-steel racks and air to approximate self-absorption of the radiation source. The radiation source term for the fuel region noted above was derived from the ORIGEN-ARP/ORIGEN-S modules within SCALE6.1 (Reference 9). The conversion factors used to convert both energy dependent gamma and neutron flux to dose rates will be based upon ANSI/ANS-6.1.1-1977. Point detectors were used in the model at the spent fuel walkway, Auxiliary building roof, at ground level 10 feet and 100 feet from the railroad siding door (1 004-1 ), the control room operating space and the closest approach to the FCS EAB (-900 meters south southwest measuring from containment centerline). Only the two detectors which were of importance to the purpose of the calculation were utilized in the final case runs. The others were of initial interest in comparisons to the San Onofre for benchmark comparisons. The dose to the plant staff and public is significantly different with a pool drain down event at 18 months after shutdown than immediately after reactor shutdown. Therefore, the last aspect of this calculation is to document the available source term of the fuel discharged from the reactor (assuming a full core offload prior to December Fort Calhoun Station CALCULATION SHEET FC08513 Revision 0 Page 17 of 269 1, 2016) and the subsequent decay of that fuel to June 1, 2018. Important for dose considerations during a loss of all SFP water inventory is also the fuel that is currently in the SFP. The gamma and neutron source term for fuel stored in the pool (i.e. fuel that has decayed longer than 3 years) was included.

5.2 Acceptance

Criteria The calculation will estimate the dose rate from gamma and neutron flux from the spent fuel. With previous industry calculations (Reference

12) indicating very little dose from the n-gamma reaction, no n-gamma dose was determined.

This is also indicated by the results of FC08514 (Reference

9) which does not produce that type of source from ORIGEN-ARP. It is expected that gamma dose rate will be the dominate contributor for integrated dose. A 95% confidence interval will be evaluated for the dose rate. The DOE dose at the EAB is expected to be below the 50-mrem in a year for members of the public or% the TEDE dose for member of the public as defined in 10 CFR 20. The dose rate in the Control Room is expected to be below 15-mR/hr as defined in NUREG-0737 (Reference 22). In addition, the 15-mR/hr is consistent with the Control Room emergency action level for the new shutdown EALs (Reference 21 ).

Fort Calhoun Station CALCULATION SHEET FC08513 Revision 0 Page 18 of 269 5.3 Identification of Computer Code MCNP6Ž is a general-purpose, continuous-energy, generalized-geometry, time dependent, Monte Carlo radiation-transport code designed to track many particle types over broad ranges of energies. MCNP6 represents the culmination of a year effort to merge the MCNP5Ž [X-503] and MCNPXŽ [PEL 11] codes into a single product comprising all features of both. For those familiar with previous versions of MCNP, the code has been expanded to handle a multitude of particles and to include model physics options for energies above the cross-section table range, a material burnup feature, and delayed particle production. Expanded and/or new tally, source, and variance-reduction options are available to the user as well as an improved plotting capability. Although MCNP6 is simply and accurately described as the merger of MCNP5 and MCNPX capabilities, the result is much more than the sum of these two computer codes. MCNP6 is the result of five years of effort by the MCNP5 and MCNPX code development teams. These groups of people, residing in the Los Alamos National Laboratory's (LANL) X Computational Physics Division, Monte Carlo Codes Group (XCP-3), and Nuclear Engineering and Nonproliferation Division, Systems Design and Analysis Group (NEN-5, formerly D-5}, have combined their code development efforts to produce the next evolution of MCNP. MCNP6.1/MCNP5/MCNPX is maintained and provided by the Radiation Safety Information Computation Center from Los Alamos National Laboratory, Los Alamos, New Mexico for the U.S. DEPARTMENT OF ENERGY. MCNP 6.1 is maintained in OPPD SWIMS, approved by (Software Change Review Committee (SCRC). 5.4 MCNP Benchmark MCNP is widely used and accepted by the nuclear utility industry to perform radiological analysis. The following case from the MCNP Installation files was run for comparison to ensure MCNP6.1 was installed properly. The version utilized in this calculation was MCNP compiled version as delivered by LANL and thus no changes to the code have been made. -Hall105a.txt, "a modified hallway problem with gamma source," was used in this calculation as a benchmark since this case uses some similar materials and a gamma source term. The results of the benchmark are shown in Attachment E. Comparison of the tally results and resulting statistical comparisons show excellent agreement and provide a basic confidence that MCNP6.1 was installed correctly. MCNP5 and MCNP6 can be utilized for radiation dose analysis as intended. The test case was run with both MCNP5 and 6. The case output from the installation was run using MCNP5, and because of computer machine CPU processing differences and updated cross section libraries, the results are not identical. The MCNP5 and MCNP6 test case results, as installed, are identical with exception of runtime. Fort Calhoun Station CALCULATION SHEET FC08513 Revision 0 Page 19 of 269 6.0 Model Geometry Overview Fort Calhoun Station is located between Nebraska Highway 75 and the Missouri River at 96 degrees, 4 minutes and 39 seconds west longitude and 41 degrees, 31 minutes and 14 seconds north latitude in Washington County, Nebraska, on the southwest bank of the Missouri River as shown on Figure 6.1.1-1 (Reference 14.67). The Exclusion Area Boundary (EAB) for FCS is shown in blue. The minimum Distance to the EAB is 910 meters at the 187 -degree radial of the containment building (Reference FCS Technical Specification 4.1 ). The actual value used in the model is 904.4 meters. / Figure 6.1.1-1 FCS Site Layout with EAB (USAR Figure 1.2-2, Reference 14.67) / / / $ / / *c. / I v4tr I "ilcc .ff' / -9c / * &'/ / / / / // ,....._ SITE BOUNOERY ( I I I l Fort Calhoun Station CALCULATION SHEET FC08513 Revision 0 Page 20 of 269 To calculate the limiting dose rates at the EAB, the closest point at the site EAB was chosen. This was determined to be at the at site access from Highway 75, shown on Figure 6.1.1-2 (Reference 14.67). This was evident, with the spent fuel pool located in the southwest portion of the auxiliary building, which is southwest of containment (shown in blue). Another attribute contributing to the Highway 75 EAB location was the elevation at highway 75 is greater than 1 080' above sea level (USAR Section 2.3 and Reference 14.42). The elevation at the Highway 75 EAB location is above the spent fuel pool walkway of 1 038' (Reference 14.9) which provides more of a direct line-of-site path to the radiation source. Other features of the model for this calculation, only the containment and the auxiliary building were modeled ignoring the radwaste building and the old warehouse, both of which are west of the auxiliary building. The EAB distance utilized (904.4 meters) is based upon review of Technical Specification 4.1 (EAB distance is 910 meters from Containment centerline).

The containment basemat is at an elevation of 979' above sea level (Reference 14.14. And every plant elevation (dimension "Z") modeled in MCNP is based upon that reference elevation from the 979' value and convert feet to centimeters (30.48 cm/ft). The same approach is utilized for dimensions in the "X" and "Y" dimensions. East to West is -X to +X and South to North is -Y to +Y, utilizing the containment centerline at X and Y = 0. 6.1.1 Photon Flux-to-Dose Rate Conversion Factors For the purposes of this calculation the ANSI/ANS-6.1.1-1977 neutron and photon dose rate conversion factors from Reference 15 and presented in Reference 1 are used.

The source material M3 is comprised of a homogenized mixture of spent fuel, stainless steel storage racks (with boral absorbing panels) and because the spent fuel pool is drained of all water, dry air. Materials utilized in MCNP are defined using the material card (Mn), where "n" is the number of the material and materials are specified by their constituents using the nuclide identifiers found in the in the MCNP libraries (Reference 1). Reference 5 provides a list of over 300 commonly used materials with the specification of elements by nuclide in either weight percent or atom fraction. This was utilized for materials M1, M2, M4 and MS. Material M1 The construction of the plant (refer to references 14.12 -14.37) shows that the structures (floors walls and roofs were built with reinforced (rebar) concrete. Using ordinary concrete with a nominal density 2.35 g/cm 3 (Reference

5) is a representative value for structural concrete.

FCS Contract 759 (Reference

6) specifies a minimum density of 145 lbs/ft 3 (2.32 gl cm 3) for both Class A and B concrete not accounting for the rebar and 225 lbs/ft 3 (3.6032 gl cm 3) for Class C "heavy concrete" which was utilized in shielding applications.

With the addition of rebar, as a reinforcing component, the concrete density is greatly increased and thus reduces particle transportation by attenuating the photon or neutron by either scatter or absorption. Thus, the density of 2.35 g/cm 3 for all structures represents a nominal value particle transport and easily modeled. The isotopic composition of ordinary concrete in the MCNP model is taken from Reference 5 and listed in Table 6.1.2-1.

Using air with no moisture (Assumption 4.2) simplifies the model as the water molecules increase the density and reduce particle transport. The isotopic composition of dry air in the MCNP model is taken from Reference 5 and listed in Table 6.1.2-2. Table 6.1.2-2 Isotopic Composition of Dry Air (Reference 5, Material M2) Element (MCNP ID) Model Composition (Atom Density) N (7014) 0.000039 0 (8016) 0.000011 Density (g/cm 2) 0.001205 Materials M4 and M5 The interior door of the railroad siding, door 1 004-1 A, was modeled as a solid sheet of 20-gauge steel (Assumption 4.3). Thus, the rollup door is comprised of interlocking pieces that are shown on OPPD drawing 232552 (Reference 14.60), which indicates material overlap. Since this overlap increases the effective thickness of the door, modeling the door as a single sheet of carbon steel simplifies the calculation. For simplicity, the exterior door of the railroad siding, door 1004-1C, was modeled as one solid panel (Assumption 4.4), utilizing the panel dimensions as shown on drawing G-576, sheet 20 (Reference 14.65). Since this overlap also increases the effective thickness of the door, modeling of both doors as single components was a conservative approach, in that the objective is to determine the best estimate of dose at the EAB. This allows more particles to transport to the site boundary. Door 1 004-1 A construction is of 20-guage steel and Door 1 004-1 C utilizes insulation wrapped in 14-guage carbon steel (Assumptions 4.4 and 4.11). The isotopic composition of carbon steel used in the MCNP model is taken from Reference 5 and listed in Table 6. 1.2-3.

The exact composition was not available; therefore, the best suitable material found in Reference 5 was utilized. Polyisocyanurate is found in Reference

5. The composition of Polyisocyanurate used in the MCNP model is taken from Reference 5 and listed in Table 6. 1. 2-4.

Therefore, all components of the fuel assembly, storage racks and air are to be weight averaged over the space taken up by the components in the spent fuel pool. Reference 10 provides a breakdown of fuel assembly hardware by axial region of the fuel assembly.

This breakdown is shown in Table 6.1.2-5, which lists by mass, the components of fuel fabricated by AREVA. This table was for a different approach to modeling a fuel assembly, as the materials are sub-divided in to regions Upper End Fitting, Plenum, Active Fuel and Bottom End Fitting. For the purposes of this analysis, the combining of masses for all four (4) regions was utilized in order to calculate the total mass of all spent fuel in the FCS spent fuel pool.

U02 atomic mass is 237.9414516 + (2 x 15.9994) = 269.9414516. -U/U02 Ratio is 237.9426516/269 .9414516 = 0.88146. -Mass of U02 = 388.6/0.88146 = 440.859 kg I assembly To get a representative mass of all fuel in the spent fuel pool, an approximation of the enrichment of the fuel located in the FCS spent fuel pool is necessary. From OPPD calculation FC08514, Attachment 10.2, which lists all FCS fuel on site by serial number and enrichment, the enrichment values were averaged with a value of 3.509 weight percent U-235. See Attachment "U-235" for the calculation of the average enrichment and calculation for atomic weight for Uranium at 3.5 weight percent U-235. Since the use of the enrichment is to assist in determining weight, an approximate value is adequate. The average enrichment for the fuel in the spent fuel pool used was 3.50% U-235. This provides a nominal value to calculate Uranium and Uranium Oxide masses and volume occupied by the Uranium Oxide, necessary in determining the source term density. Fort Calhoun Station CALCULATION SHEET FC08513 Revision 0 Page 32 of 269 Spent Fuel Racks portion of M3 Adding the mass of the Spent Fuel Racks to the fuel components of the M3 composition was accomplished by first determining the volume of the parts of the Region I and Region II racks. This is necessary because the racks are of differing designs. The Region I racks have a much larger cell-to-cell pitch by design than the Region II racks, allowing for a flux trap between cells and therefore, more air between cells when the spent fuel pool is drained. The two different designs are identified on Holtec Drawings 1000 through 1004 and 1007 (References 14.51 through 14.57). Drawing 1000 (Reference 14.51) shows the overall layout of the spent fuel racks. In addition, as shown in the upper right corner of the drawing, each defined rack has the base dimensions and the number of cells within each rack. The source term volume neglects the area below the fuel assembly alignment pins. At the bottom of the racks, a%" plate of Stainless steel was not included in the weight or volume calculations (References 14.53 and 14.55). The racks, comprised of differing thicknesses of stainless steel panels, are the main structure with boral panels used for neutron absorption with regard to maintaining the configuration subcritical. Region I Volume Drawing 1000 (Reference 14.51) shows Region I racks as A1 and A2 with the larger cell pitch. The Region I racks, as shown on drawing 1001 (Reference 14.52) identifies a grouping of 4 rows by 5 columns and each cell is identified by a number 1 through 20. Each 4 by 5 grouping of cells is repeated 4 times defining racks A 1 and A2. Utilizing these uniquely designed 20 cells, the panels are catalogued by their individual parts. Table 6.1.2-7 and Table 6.1.2-8 are utilized to arrive at the total number of parts and dimension for each cell. The dimensions for each box or panel are found on Holtec drawings 1001 and 1002 (References 14.52 and 14.53). The equations for volumes by part in Table 6.1.2-8 are shown in the notes 1 through 5 after the table.

This work was documented in FC08514, and a standard CE 14 x 14-assembly type was used versus building a specific AREVA fuel type. The fuel design used in the FCS reactor is a standard CE 14 x 14-fuel type even when manufactured by AREVA or Westinghouse or Exxon. Benchmark calculations for the source term were produced to check against explicit AREVA 14 x 14 ORIGEN output and the source term generation was found to be well within statistical acceptance and documented in FC08514. As noted in the referenced calculation radial or axial peaking factors were not applied to the source term since the assemblies were modeled with plant specific burnups from GARDEL/CECOR online measurement processes. The ARP/ORIGEN-S calculations were performed to generate a gamma and neutron source for a time point at eighteen months after reactor shutdown. A fourteen-month source term was then scaled from further ORIGEN runs on core offload fuel batches. These two time points are considered relevant for the dose analyses. The explicit operating parameters used to generate the source term can be found in FC08514 and will not be discussed further in this calculation. The source term generated for gamma, (photons) included light elements, actinides and fission product calculations. The gamma radiation that results from neutron interactions (i.e., neutron/gamma reactions) was not included and that discussion is justified in FC08514, and has precedent with the SCE response regarding source term generation. Additionally, FC07586 provided justification for not including the neutron/gamma reactions. Page 28 of FC07586 notes that both the neutron radiation source term in a spent fuel assembly and gamma radiation that results from neutron/gamma reactions, are orders of magnitude less than energy deposition potential from a spent fuel assembly gamma radiation source term. Therefore, FC07586 noted that the spent fuel assembly neutron radiation source terms and gamma radiation that results from neutron/gamma reactions were not further pursued for spent fuel pool concrete gamma heating. The energy deposition and energy strength has direct correlation to dose as well. This calculation will include neutron source term for completeness related to dose consequences. It will not however, include any neutron/gamma interactions that could potentially produce further gamma sources. By far the total gamma source strengths due to fission products, actinides, and light element activation products in the spent fuel are the dominant radiation source term as shown by the source term total strength. The ORIGEN-ARP/ORIGEN-S computer codes were run to obtain time dependent gamma radiation source terms for 18 standard gamma energy groups and to obtain neutron radiation source terms for 44 standard neutron energy groups. The 18 group structure ORIGEN2 was used for the gamma calculations. The 44-group structure ENDF5 was used for the neutron calculations. Details about those calculations are found in FC08514. Gamma and neutron energy bin values (MeV) are provided in the tables noted below. There are 19 gamma energy bin values in descending order and 45 neutron energy bin values in descending order. Fort Calhoun Station CALCULATION SHEET FC08513 Revision 0 Page 55 of 269 The radiation source term within the active fuel region of an assembly and stored in the spent fuel racks is homogenized over the active fuel region in the spent fuel pool. The source term generated is uniformly distributed over the surface of the fuel region of the spent fuel pool. No axial power distribution was applied to the source term. This is considered conservative as some fuel cycles have axial power distributions that have a large fraction of power in bottom segments of a spent fuel assembly and as such, the source would be weighted towards bottom of the fuel. Two source terms were generated, one for a fourteen-month post shutdown event, and one for an eighteen month. The source terms generated for these time points were for neutron and photons (gammas). The source term was generated by energy group so that it can be readily input into MCNP calculations. No adjustment to this source term is required as discussed above. The following tables are used to calculate the dose rates at fourteen and eighteen months after reactor shutdown. The first set of tables are for gamma dose calculations and represent the photon source term from the fuel in the spent fuel pool. The energy groups are listed by the output number of the group. The table below shows the energy boundaries for each energy group, so for example output group 1 has an energy bin or boundary of 0 to 0.02 MeV. Output group 18 has an energy bin or boundary of 8 to 11 MeV.

Since majority of fission products and some fuel structural activation products produce gammas within this range, they are distinctly dose relevant for personnel and the source term in these energy groups would be expected to dominate the dose calculation. The output group structure with energy boundaries is important, as they need to correlate to the MCNP input decks as well. The actual table of total photons gamma spectrum as a function of energy output group is provided next. The far right column represents the total core offload and old fuel source term that must be input into MCNP for the eighteen month calculations.

The first table shows the neutron energy output group by energy boundaries such that the same binning process has to be preserved for the MCNP calculations. That is the strength of the source for that energy group (and the energy boundary itself) has to be specified so the code can track the particle interactions by energy. For example, the far right hand column represents the Group Output number, the two middle columns represent the energy boundary ranges, the far left column represents the ORIGEN Maximum Neutron Energy group structure. For example, the far left column value of 1 represents the ORIGEN energy boundary from 2E+1 to 2E+ 7 eV, but it's output group is number 44. The energy groups must remain consistent for the dose calculations. That is the number of neutrons for a particular output group must align with the energy for that group structure.

The total source term for gammas and neutrons for the MCNP model is similar to that which was calculated for the SCE source term (Reference

12) and comparable dose predictions would be expected.

The gamma and neutron source terms noted above in the previous tables were input directly into the MCNP files for dose calculations related to the control room and exclusion area boundary.

Term Output Dose Importan t Nuclides as a Function of Cooling Time The following output, Figure 6.1.5-1 , from ORIGEN-ARP (FCS DD1 18 month Curies.out) for the highest enrichment assembly that is being oftloaded from the Cycle 28 core was r un to show the measure of curies for the important dose nuclides. The nuclides that were plotted are those nuclides that have relatively high dose conversion factors for external gamma. These nuclides were tracked through the three-cycle fuel irradiation , and then subsequent decay corrected in the ORIGEN calculation process. The output shown is a function of time after the assembly has been discharged from the core (DD1 sub-batch assembly). The output reported is in curies for a single assembly discharged. The units for cooling time are in years.

After 1.5 years of cooling the output for this assembly shows that the only nuclide that has relevant curie measure is Kr85 at 5.327E3 Curies. After 1.5 years of decay, the fuel assembly activity available for release is predominately Kr85 (noble gas). The potential release of Kr85 from an assembly would not be expected to contribute to groundshine since noble gases do not interact with soils or plateout. Therefore, there is no potential for plateout of Kr85 to the soil and a potential groundshine dose nor could it be released from the soil for dose contribution. Based upon the isotopes of dose significance identified, Kr85 is only one available for potential release at this time-point (only if cladding compromised) there would be no expected contribution of dose from a groundshine itself. Therefore, this calculation assumes no clad failure , and as such, even though 1129 and Cesium's would be of significance in total Curies they are not available for potential groundshine contribution. Figure 6.1.5-2 illustrates the decrease in curie measure for the nuclides tracked above that would be potentially relevant for groundshine dose. This figure shows how quickly the tracked nuclides decay. The remaining nuclides within the assembly are what are modeled and tracked for source term related to direct and scattered shine, (i.e. Cs, Sr and Y). That output is documented as part of the source term generated for direct and scattered gamma and neutron contribution in FC08514. This calculation does not document a boil off or fuel handling accident, and as such inhalation doses are not required to be computed.

Review of the FCS USAR indicates the minimum LPZ is at nine (9) miles versus nominal 10 miles for emergency planning zones. In order to keep the model simplified, only the structures of interest to the problem are modeled. These include the portions of the FCS auxiliary building (Rooms 3, 25, 25A, 68, and 69) containment, the control room and the topography at the EAB. Containment is modeled because of the amount of area it takes up and provides a source of material that helps scatter particles back to the south and west EAB areas. Figure 6. 1. 5-1 and Figure 6. 1. 5-2 show the overview of the plant areas as modelled in MCNP. Figure 6.1.5-1 shows the overview of the SFP, Containment, the Control Room and the Room 69 adjacent area between the control room and the SFP above the 1025' plant elevation in the X-Y plane. Figure 6.1.5-2 shows the horizontal slice of the SFP, including the fuel, Containment, the and the area above the SFP in the X-Z plane.

However, Figure 6.1.1-4 depicts the Y-Z cutaway allowing the distance Fort Calhoun Station CALCULATION SHEET FC08513 Revision 0 Page 66 of 269 from the plant and the elevation change at the EAB to be shown. This is where the EAB dose detector was located, 900 Meters South-Southwest of the plant. 6.2.1 Model Geometry Figure 6.1.5-4 MCNP Model Plant Cutaway Slice (Y-Z) -Looking towards plant North -The starting point (model origin) of plant to model the FCS geometry was the containment centerline at the 979' elevation. Each section of the plant modeled in MCNP utilized plant architectural and structural drawings to ascertain wall locations thicknesses, and elevations. In order to simplify the review process, the MCNP cards shown are grouped by structure and do not match the order of cards as needed to execute MCNP. 6.2.1.1 Containment References 14.12 through 14.17 provide the details of containment. Containment is modeled as a right circular cylinder with the base at the 991' elevation, 12 feet thick (365. 76 em), the internal radius of 55 feet , 0.25 inches (1677.35 em) and external radius of 58 feet, 10 % inches (1795.15 em). The containment dome is not spherical; this resulted in the approximation as a right circular cylinder (rcc). This is acceptable since the containment design more closely reflects the geometry of a cylinder with containment extending well above the top of the auxiliary building, thus any particles leaving the east side of the of the auxiliary building are either scattered back, absorbed or otherwise lost. Reference 14.13, was utilized to determine the approximate height of the cylinder at the 1121.5' elevation (4343.07 em) utilizing the average of the containment arc. Since the vertical rise of the tendon structure is approximately 18 feet, 3.5 inches, the inside of the containment cylinder is 1103.21' (3785.87 em). The containment tendon structure at the top of the containment Fort Calhoun Station CALCULATION SHEET FC08513 Revision 0 Page 67 of 269 provides additional concrete material included due to the thick containment walls at that elevation. Defining containment was done utilizing the surface cards shown in Figure 6.2.1-1. The surfaces defined are the top and bottom elevations of the containment basemat, 3230 and 3260, respectively. The right circular cylinder surfaces 5000 and 5100, centered at 0, 0, 0 and 0, 0, 365.76 are the exterior and interior walls of containment, respectively. c 3230 3260 c pz pz 365.76 0.00 c Containment Building c c Figure 6.2.1-1 Containment Geometry Cards $ Top of Containment Basemat (991'0") $ Bottom of Containment Basemat (979'0") 5000 rcc 0. 0. 0. 0. 0. 4343.07 1795.15 $ CAN Outer 5100 rcc 0. 0. 365.76 0. 0. 3785.87 1677.35 $ CAN Inner c The Cell cards then define the relationship of the surfaces as show in Figure 6.2.1-2.

The surfaces that define the structure within the Auxiliary building are based upon References 14.1 through 14.37. Each structure defined will reference the specific drawing utilized. Figure 6.2.1-9 shows the MCNP surface cards for Rooms 3, 25, 25A, 67, 69 and 77 (Control Room). The auxiliary building, control room and areas between the spent fuel pool are included because the dose to the control room operator was to determined. The dose was calculated by locating an F5 detector (flux at a point) in the at-the-controls area of the control room, where the operators are required to be stationed 24 hours-a-day, 7 days-a-week (Reference 17). Room 69 encompasses a large open area of the Auxiliary building north and east of the spent fuel pool at the 1 025' elevation. This area is also abutted up to the containment wall. An image from the MCNP Vised software shows the model which includes adjacent area in a 3-D layout. See Figure 6.2.1-8.

The fuel source is the simplest surface and cell to define from a geometry perspective. Because the fuel and spent fuel racks have been homogenized, defining the source was modeled using a single right parallel piped, fitting into the shape of the spent fuel pool. These surfaces utilize the exact elevations of the top and bottom of the spent fuel racks and the perimeter of the spent fuel pool. Table 6.2.1.4-5 provides the dimensional information utilized to define the fuel source that includes the specific drawing utilized.

The SDEF defines the functionality of the source. Since the sources for these cases are 3-dimensional and energy dependent (as determined by the ORIGEN cases), these sources must be defined using, the dimensions of the fuel surface geometry, which are shown on the Sl1 (x), Sl2 (y), Sl3(z) cards matching the definitions of fuel geometry. The SP1, SP2, and SP3 cards accompanying the Sl cards indicates the functionality of the source is based upon a distribution of 0 to 1, which reflects a probability of the source (1) is in effect at all times. The energy dependence of the photons and neutrons is identified similarly using the Sl4 and SP4 cards.

The dose rate (neutron and gamma) at the EAB 14-months after shutdown with the Spent Fuel Pool completely drained is 1.66E-03 mRem/hr. Therefore, the DOE dose to the public from this event is 14.6 mrem, which is less than the 10CFR20 limit of 50 mRem. The dose rate (neutron and gamma) from this event in the Control Room is 2.32E-03 mRem/hr. which is_below 15-mR/hr as defined in NUREG-0737 (Reference 22). The dose rates (neutron and gamma) 18-months after shutdown at the EAB with the Spent Fuel Pool completely drained is 1.38E-03 mRem/hr and the Control Room is 2.23E-03 mRem/hr. The reported dose rates above are determined by averaging MCNP tally output for Gamma (Table 7-1) and Neutron (Table 7-2). Because the number of histories for the Neutron results were run at different times (and required considerably more computer execution time than the gamma cases), the 14-month neutron value reported was determined by a ratio of the tally result at the last point (nps=1.0E+08) to the 18-month tally value (nps=1.006633E E+08). The tally trend on both cases were similar, ensuring the ratio was valid. The full tally analysis are shown in Attachment D spreadsheets ("tallies_gamm20161017.xlsx" and "tallies_neut20161 017).

This is due to the 14-month run did not utilize the same total number of histories (7.25E+08).

To calculate the upper boundary, the error for the 18-month case was applied. Based upon the results of the MCNP cases , dose rates at the EAB and control room, have larger relative errors than expected. Notwithstanding, the dose rates including a two-sigma (standard deviation) error, which did meet the objective of this calculation. See Table 7-3 for gamma and neutron dose rate results with the error applied. Dose rates are well below the acceptance criteria of less than 15-mR/hr as defined in NUREG-0737 (Reference

22) in the Control Room. In addition, the 15-mR/hr is consistent with the Control Room emergency action level for the new shutdown EALs (Reference 21 ). In addition, the DOE dose is less than the 50-mrem in a year for members of the public or % the TEDE dose for member of the public as defined in 10 CFR 20.

For the14-month gamma dose rate at the EAB, the upper boundary is 1.0416E-03 mRemlhr + (1.96 x 1.0416E-03 mRemlhr x 0.2935) = 1.64E-03 mRemlhr. (b) The relative errors for these dose locations did not pass all the MCNP 10 statistical checks and the errors are greater than 0.05. Table 1.1: " Guidelines for Interpreting the Relative Error" of the MCNP6 User's Manual indicates that relative errors between 0.05 and 0.50 imply that the tally results could be off by a factor of a few. Due to the dose rates being significantly low, the results indicate a large margin to the acceptance criteria. (c) The 14-month neutron dose rate was determined by using the ratio of the mean values at 1.0E+08 histories for the 14-month and 18-month runs. This is due to the 14-month run did not utilize the same total number of histories (7.25E+08). To calculated the upper boundary, the error for the 18-motnh case was applied. This is a valid approach since the histories show identical trends with respect to mean value, error, variance, pdf and figure of merit.

The masses of the uranium isotopes are calculated by multiplying the mass of uranium in anassembly (i.e., 388.6 kg per Design Input Table 2-1) by the uranium isotope weight percents. The mass of U02 in the uranium blend is calculated by multi pi ying the mass of uranium in an assembly by the ratio of the atomic mass of U02 i n the uran ium blend to the atomic mass of the uranium blend. The mass of oxygen in the uranium blend is the mass of U02 in the uranium blend minus the assembly mass of uranium in the blend.

The results are 4E-05-mR/hr. MicroSkyshine will only except energies between 0.1 to 10-Mev, so below 0.11 didn't use, and flux for 11-MeV was entered as 10-MeV. I might make a run adding all lower energies into 0.1 and see what the difference is between the two runs. Steve

COMMONWEALTH OF VIRGINIA CITY OF LYNCHBURG AFFIDAVIT ss. 1. My name is Gayle Elliott. I am Deputy Director, Licensing & Regulatory Affairs, for AREVA NP Inc. (AREVA NP) and as such I am authorized to execute this Affidavit.

2. I am familiar with the criteria applied by AREVA NP to determine whether certain AREVA NP information is proprietary.

I am familiar with the policies established by AREVA NP to ensure the proper application of these criteria.

3. I am familiar with the AREVA NP information contained in Calculation FC08513, entitled, "EAB Radiation Shine Dose 18 Months Post Shutdown with the SFP Drained," and referred to herein as "Document." Information contained in this Document has been classified by AREVA NP as proprietary in accordance with the policies established by AREVA NP for the control and protection of proprietary and confidential information.

4. This Document contains information of a proprietary and confidential nature and is of the type customarily held in confidence by AREVA NP and not made available to the public. Based on my experience, I am aware that other companies regard information of the kind contained in this Document as proprietary

'and confidential.

5. This Document has been made available to the U.S. Nuclear Regulatory Commission in confidence with the request that the information contained in this Document be withheld from public disclosure.

The request for withholding of proprietary information is made in accordance with 10 CFR 2.390. The information for which withholding from disclosure is requested qualifies under 10 CFR 2.390(a)(4) "Trade secrets and commercial or financial information."

6. The following criteria are customarily applied by AREVA NP to determine whether information should be classified as proprietary: (a) The information reveals details of AREVA NP's research and development plans and programs or their results.

(c) The information includes test data or analytical techniques concerning a process, methodology, or component, the application of which results in a competitive advantage for AREVA NP. (d) The information reveals certain distinguishing aspects of a process, methodology, or component, the exclusive use of which provides a competitive advantage for AREVA NP in product optimization or marketability. (e) The information is vital to a competitive advantage held by AREVA NP, would be helpful to competitors to AREVA NP, and would likely cause substantial harm to the competitive position of AREVA NP. The information in this Document is considered proprietary for the reasons set forth in paragraphs 6(c), 6(d) and 6(e) above. 7. In accordance with AREVA NP's policies governing the protection and control of information, proprietary information contained in this Document has been made available, on a limited basis, to others outside AREVA NP only as required and under suitable agreement providing for nondisclosure and limited use of the information.

8. AREVA NP policy requires that proprietary information be kept in a secured file or area and distributed on a need-to-know basis.

9. The foregoing statements are true and correct to the best of my knowledge, information, and belief. SUBSCRIBED before me this __ I to_th __ dayof J 2016. Sherry L. McFaden NOTARY PUBLIC, COMMONWEALTH OF VIRGINIA MY COMMISSION EXPIRES: 10/31/18 Reg. # 7079129
