SUMMARY

DESCRIPTION Pursuant to 10 CFR 50.90, Southern California Edison (SCE) is submitting Amendment Applications 226, 273, and 258 for San Onofre Nuclear Generating Station (SONGS) Units 1, 2 and 3, respectively. The proposed amendments would revise the Permanently Defueled Emergency Plan (PDEP) into an ISFSl-Only Emergency Plan (IOEP) and revise the Emergency Action level (EAL) scheme into an IFSl-Only EAL (IOEAL) scheme. The proposed changes are being submitted to the NRC for approval prior to implementation, as required under 10 CFR 50.54(q)(4), 10 CFR 50, Appendix E, Section IV.B.2, and 10 CFR 72.44(f).

By letters dated June 28, 2013 (Reference 1) and July 22, 2013 (Reference 2), SCE submitted the certification of permanent removal of fuel from the reactor vessels for SONGS Units 2 and 3, pursuant to 10 CFR 50.82(a)(1 )(ii). Consequently, as specified in 10 CFR 50.82(a)(2), the 10 CFR Part 50 license for SONGS no longer authorizes operation of the reactor or emplacement or retention of fuel into the reactor vessel. The Post-Shutdown Decommissioning Activities Report (PSDAR) for SONGS dated September 23, 2014 (Reference 3), documented that SCE expects to have all spent fuel transferred to the Independent Spent Fuel Storage Installation (ISFSI) in 2019. In addition, SONGS Unit 1 has been permanently shut down since 1993 and is in the decommissioning phase. Above-ground structures have been dismantled. Unit 1 fuel is stored in the Independent Spent Fuel Storage Installation and in the GE-Hitachi Morris facility.

To reflect the reduced scope of potential radiological accidents with spent fuel in dry cask storage within the ISFSI, SCE proposes a new EAL scheme and corresponding emergency plan changes.

The proposed IOEP is for the operation of the ISFSI. This plan would only be implemented after all spent fuel has been removed from the spent fuel pools and placed in dry storage within the ISFSI. Implementation of the IOEP would involve SONGS applying administrative controls for methods to control the potential dispersal of radiological source material.

The proposed IOEP continues to rely on previously granted exemptions from certain emergency planning requirements (Reference 4) as the basis for these exemptions has not changed and remains in effect.

There are no existing license amendment requests associated with the emergency plan currently docketed for SONGS. Therefore, no disposition of other license changes, as they relate to this license amendment request, is needed. Consistent with the condition that the proposed IOEP may be implemented only after all spent fuel has been removed from the spent fuel pool and placed in dry storage within the ISFSI, SCE License Amendment Applications 225, 272, and 257 (dockets 50-206, 50-361 and 50-362, respectively) (Reference 5), *proposed a revision to the Technical Specification 4.3, "Fuel Storage," stating spent fuel shall not be stored in the spent fuel pool.

EVALUATION OF THE PROPOSED AMENDMENT ISFSl-Only Emergency PLAN (IOEP) and Emergency Action Level (EAL) Scheme

2.0 PROPOSED CHANGE

The proposed amendment would modify the SONGS license by revising the emergency plan and the associated emergency action level (EAL) scheme. The proposed changes reduce the scope of onsite emergency planning requirements to reflect the reduced scope of potential radiological accidents with all spent fuel in dry cask storage within the ISFSI. After all spent fuel is in dry cask storage within the ISFSI, the number and severity of potential radiological accidents is less than when spent nuclear fuel was stored in the spent fuel pool. Therefore, the offsite radiological consequences of accidents possible at SONGS are substantially lower.

There continues to be no need for offsite emergency response plans at SONGS because no design basis accident or reasonably conceivable beyond design basis accident can result in radioactive releases that exceed Environmental Protection Agency (EPA) Protective Action Guides (PAGs) (Reference 6) beyond the Exclusion Area Boundary (EAB).

SCE has developed a methodology for determining when to apply administrative controls that would be adequate to limit potential dispersal of radioactive material during decontamination and dismantling of radioactive systems, structures, and components contained in the non-operational nuclear Units. These administrative controls ensure that if a radiological release were to occur, it would not exceed two times the Offsite Dose Calculation Manual (ODCM) limits (2 x 1500 mrem/year) at the EAB for 60 minutes (and therefore not result in doses to the public above EPA PAGs beyond the EAB).

For potential liquid radioactivity releases, the SONGS UFSAR provides analysis for two events.

For the Radioactive Waste System Leak or Failure (Release to Atmosphere), the UFSAR states that consequences would be less than 100 mrem, which is below the acceptance criterion of 2 x 1500 mrem/year. For the Postulated Radioactive Releases Due to Liquid Tank Failures, the UFSAR states that there is no credible accident that results in releases exceeding 10 CFR 20 limits. As the ODCM limits are based on 10 CFR 20, any dose consequences from a liquid radioactivity release would also be below two times the ODCM limits at the EAB for 60 minutes (and therefore not result in doses to the public above EPA PAGs beyond the EAB).

The current EAL scheme was approved for use at SONGS on June 5, 2015 (Reference 7), and is based upon NEI 99-01, Revision 6 (Reference 8). The proposed EAL scheme remains based on NEI 99-01, Revision 6, as appropriate for the ISFSl-only condition at SONGS.

2.1 Summary of Major Changes The major changes to the SONGS Emergency Plan are:

1. Removal of the various emergency actions related to the spent fuel pool.

2. Removal of non-ISFSI related emergency event types.

3. Replacement of the "Shift Manager" title with the ."ISFSI Shift Supervisor (ISS)" title as the position which assumes the Emergency Director's responsibilities.

4. Revision of the emergency response organization.

Page2

EVALUATION OF THE PROPOSED AMENDMENT ISFSl-Only Emergency PLAN {IOEP) and Emergency Action Level (EAL) Scheme The off-normal events and accidents addressed in the SONGS ISFSl-Only Emergency Plan are related to the dry storage of spent nuclear fuel at the ISFSI and include only off-normal, accident, natural phenomena, and hypothetical events and consequences as presented in the NU HOMS Certificate of Compliance (CoC) 1029 (Amendments 0 and 1) Horizontal Modular Storage System Updated Final Safety Analysis Report (NU HOMS UFSAR), and in the HOLTEC CoC 1040 (Amendment 1 and Proposed Amendment 2) HI-STORM System Final Safety Analysis Report (FSAR). After all fuel is removed from the SONGS spent fuel pools, there will no longer be any potential for the accidents previously described in the SONGS Emergency Plan that would increase risk to the health and safety of the public that specifically related to the storage of the spent fuel in the spent fuel pool. After the transfer of the spent fuel to the ISFSI, the spent fuel storage and handling systems will be removed from operation consistent with the PSDAR for SONGS dated September 23, 2014 (Reference 3).

2.2 Elimination of Spent Fuel Pool and Radioactive Release Initiating Conditions and EALs, The initiating conditions (ICs) and EALs associated with emergency classification in the current emergency plan are based on NEI 99-01, Revision 6. Specifically, Appendix C of NEI 99-01 contains a set of ICs and EALs for permanently defueled nuclear power plants that had previously operated under a 10 CFR Part 50 license and have permanently ceased operations.

After all spent fuel has been removed from the spent fuel pool and placed in dry storage within the ISFSI, the NEI 99-01, Appendix C, ICs and EALs that are associated with the spent fuel pool are no longer required to be in the emergency plan. Additionally, certain ICs and EALs whose primary function is not associated with the spent fuel pool are also no longer required to be in the emergency plan when administrative controls are applied to limit the potential dispersal of radioactive material and the offsite consequences of uncontrolled effluent releases.

Therefore, the ICs listed in Table 1 below are being deleted from the currently approved emergency plan for SONGS. The ICs being deleted are either associated only with spent fuel pool operation or are ICs for which administrative controls to limit possible effluent releases have been established.

The currently existing SONGS ICs and EALs not listed in Ta_ble 1 above are being retained.

The EAL ICs being deleted include all ICs associated with the categories of abnormal radioactivity release and system malfunction. These two categories apply only to spent fuel pool operation.

One new EAL is being proposed in IC E-HU1, "Damage to a loaded cask CONFINEMENT BOUNDARY." The new EAL E-HU1 .2 provides threshold values for the AREVA ISFSI and the new HOLTEC ISFSI based on the generic AREVA and HOLTEC Technical Specification values provided in the respective Certificates of Compliance.

The EAL ICs being retained in the emergency plan are appropriate to address the condition of an ISFSl-only facility (no fuel stored in the spent fuel pool).

2.3 Emergency Response Organization Revision A Resource Manager is provided to assist in assessing the event and obtaining needed resources. The Resource Manager is required to be in contact with the Emergency Director within 2 hours2.314815e-5 days <br />5.555556e-4 hours <br />3.306878e-6 weeks <br />7.61e-7 months <br /> of classification of an Unusual Event or ALERT. The Resource Manager augments the Emergency Director by assisting in assessing the emergency condition and coordinating required resources, including public information interface. Services provided to the Emergency Director by the Resource Manager can be provided remotely and do not necessitate an onsite response of the Resource Manager. By responding remotely, the actual response time is decreased with no negative impact to services and functional responsibilities provided by the Resource Manager.

Page 4

EVALUATION OF THE PROPOSED AMENDMENT ISFSl-Only Emergency PLAN (IOEP) and Emergency Action Level (EAL) Scheme Events that require entry into the ISFSl-Only Emergency Plan would be an extreme natural phenomenon (beyond design bases) or a security condition, either of which would negatively impact or restrict access to the site.

Therefore, the Resource Manager's functional responsibilities would be performed in a timely manner by not requiring the Resource Manager to physically report to SONGS during a classified emergency.

3.0 TECHNICAL ANALYSIS

3.1 Radiological Consequences of Design Basis Events The San Onofre site is located on the coast of Southern California in San Diego County, approximately 62 miles southeast of Los Angeles and 51 miles northwest of San Diego. The site is located entirely within the boundaries of the United States Marine Corps Base, Camp Pendleton, California, near the northeast end of the 18-mile shoreline. The population of the area within a 10-mile radius of the San Onofre Nuclear Generating Station is projected to increase from 59,024 in 1980 to 95,301 by 2020.

The SONGS Units 2 and 3 Updated Final Safety Analysis Report (UFSAR), Chapter 15, Accident Analyses, currently address the design basis accidents (OBA) and transient scenarios applicable to SONGS Units 2 and 3 in the permanently defueled condition with irradiated fuel stored in the SFP. Many of these postulated accidents are predicated on spent fuel being stored in the SFP. However, upon transfer of all irradiated fuel to storage in the ISFSI, the accident scenarios predicated on spent fuel storage in the SFP are no longer possible. The SONGS 1 Defueled Safety Analysis Report (DSAR), Chapter 8, Accident Analyses states that there are no remaining design-basis accidents for Unit 1, which is consistent with the condition that all spent fuel has already been removed from the Unit 1 spent fuel pool. The ISFSI is a passive system that does not rely on electrical power for heat transfer. After removal of the spent fuel from the Units 2 and 3 spent fuel pools, there are no credible fuel related accidents Hor which Certified Fuel Handler, Shift Manager, or Certified Operator actions are required to prevent occurrence or mitigate the consequences. There is no credible accident resulting in radiological releases requiring offsite protective measures.

The robust design and construction of the spent fuel storage systems selected for use at the ISFSI prevents the release of radioactivity in the event of an off-normal or accident event as described in the ISFSI storage system safety analysis reports. Leakage of fission products from a canister confinement boundary breach is *not considered to be a credible event, given the high integrity nature of the canisters' design and the additional protection afforded the canisters by the storage system.

SCE plans to use the DEGON decommissioning method (immediate dismantling), in which the equipment, structures, and portions of the facility and site that contain radioactive contaminants are promptly removed and/or decontaminated to a level that permits termination of the license after cessation of operations (Reference 3). Administrative controls that are required to be in Page 5

EVALUATION OF THE PROPOSED AMENDMENT ISFSl*Only Emergency PLAN (IOEP) and Emergency Action Level (EAL) Scheme place when decontamination and dismantlement activities of radioactive systems, structures, and components are being performed are designed to minimize the likelihood of an off-normal event, and thereby the consequences of such an event.

After all the spent fuel has been removed from the spent fuel pool, the radiological inventory (non-fuel) that remains at the reactor facility is primarily attributable to either stored liquid radioactive waste or activated reactor components and structural materials. For liquid radwaste, Chapter 15 of the UFSAR states that there is no credible accident that would exceed 10 CFR 20 limits. For activated reactor components and structural materials, there are no credible accident sequences that can mobilize a significant portion of this inventory for release. As a result, the potential accidents that could occur during the decommissioning of the reactor facility have negligible offsite and onsite radiological consequences.

With all spent nuclear fuel in dry storage within the ISFSI, the radiological status of the facility required for implementing this proposed revision to the SONGS ISFSl-Only Emergency Plan (IOEP) is summarized as follows:

• The remaining radiological source term at SONGS is not likely to create an unplanned/unanticipated increase in radiation or in liquid or airborne radioactivity levels outside of the EAB that would result in doses to the public above ODCM limits at the EAB.

• Source term accumulation from activities during decontamination and dismantling of radioactive systems, structures, and components are administratively controlled at a level that would preclude the declaration of an Unusual Event (UE).

• Necessary radiological support personnel will be administratively required to be onsite during active decontamination and dismantling of radioactive systems, structures, and components.

The IOEP and certain initiating conditions (ICs) and emergency action levels (EALs), for which administrative controls to limit possible effluent releases will be established, do not apply to decontamination or dismantling of radioactive systems, structures, and components.

• NUREG-0586 (Reference 9) supports this conclusion in the following statement.

"The staff has reviewed activities associated with decommissioning and determined that many decommissioning activities not involving spent fuel that are likely to result in radiological accidents are similar to activities conducted during the period of reactor operations. The radiological releases from potential accidents associated with these activities may be detectible. However, work procedures are designed to minimize the likelihood of an accident and the consequences of an accident, should one occur, and procedures will remain in place to protect health and safety while the possibility of significant radiological accident exists."

NUREG-0586 also makes the following supportive statement.

Page 6

EVALUATION OF THE PROPOSED AMENDMENT ISFSl-Only Emergency PLAN (IOEP) and Emergency Action Level (EAL) Scheme "The staff has considered available information, including comments received on the draft of Supplement 1 of NUREG-0586, concerning the potential impacts of non-spent-fuel-related radiological accidents resulting from decommissioning. This information indicates, that with the mitigation procedures in place, the impacts of radiological accidents are neither detectable nor destabilizing. Therefore, the staff makes the generic conclusion that impacts of non-spent-fuel-related radiological accidents are SMALL. The staff has considered mitigation and concludes that no additional measures are likely to be sufficiently beneficial to be warranted."

Accordingly, administrative controls that are designed to minimize the likelihood and consequence of an off-normal event would be implemented when decontamination or.

dismantling activities of radioactive systems, structures, and components are being performed.

Implementation of the IOEP would involve SCE applying administrative controls for methods to control the potential dispersal of the radiological source material.

Administrative controls would potentially need to be applied duririg handling of:

• . Radioactive materials collected on filter media and resins.

• Contaminated materials collected in shipping containers.

• Surface or fixed contamination on work areas that may create airborne radioactive material.

• Radioactive liquids within tanks Details of administrative control programs will be finalized in 2017. Administrative controls are expected to be similar to existing controls provided by the Radiation Protection Program and Fire Protection Program. Activities will be performed in accordance with procedures by individuals that have been trained to prevent the potential dispersal of radioactive material.

Several examples of methods to control potential dispersal of the radiological source term include limitation on dispersal mechanisms that may cause a fire (e.g., limits on combustible material loading, use of fire watch to preclude fire, etc.), placement of a berm around a radioactive liquid storage tank, or packaging contents of a shipping container within a confined boundaries and ventilation controls.

As discussed in the previously granted exemption from various emergency planning requirements contained in 10 CFR 50.47 and 10 CFR 50, Appendix E (Reference 4), an analysis of the potential radiological impact of a design basis accident at SONGS in a permanently defueled condition indicates tbat any releases beyond the EAB are below the EPA PAG exposure levels, as detailed in Reference 6. The basis for these exemptions has not changed and remains in effect for the proposed emergency plan changes.

3.2 Radiological Consequences of Postulated Events Under the previous facility condition of fuel stored within the spent fuel pool, the most severe postulated beyond design basis event involved a highly unlikely sequence of events that causes Page 7

EVALUATION OF THE PROPOSED AMENDMENT ISFSl-Only Emergency PLAN (IOEP) and Emergency Action Level (EAL) Scheme heatup of the spent fuel, postulated to occur without heat transfer, such that the zircaloy fuel cladding reaches ignition temperature. The resultant zircaloy fire could lead to the release of large quantities of fission products to the atmosphere. However, after removal of the spent fuel from the spent fuel pool, the configuration of spent fuel stored in dry storage precludes the possibility of such a scenario.

With this previously limiting beyond design basis scenario no longer possible, SCE assessed the following beyond design basis events associated with performance of decommissioning activities with all irradiated fuel stored in the SCE ISFSI. A summary of the assessments is provided below.

1. Cask Drop Event (Fuel Related Accident)

SCE is the user of general licenses for the storage of spent fuel in an ISFSI at power reactor sites in accordance with the provisions of 10 CFR 72.210.and 10 CFR 72.212. The generally licensed ISFSI at SONGS is used for interim onsite dry storage of spent nuclear fuel assemblies in both the Transnuclear Standardized NUHOMS System (NU HOMS Certificate of Compliance (CoC) 1029 (Amendments 0 and 1)) and in the HOLTEC*

HI STORM System (HOLTEC CoC 1041 (Amendment 1 and Proposed Amendment 2)).

As documented in the storage system safety analysis reports, analysis of the normal and off-normal events, including drop events, determined that canister drops can be sustained without br:eaching the confinement boundary, preventing removal of spent fuel assemblies, or causing a criticality accident. There are no evaluated normal conditions or off-normal or accident events that result in damage to the canister producing a breach in the confinement boundary. Neither normal conditions of operation, nor off-normal events preclude retrieval of the fuel for transport and ultimate disposal.

As documented in the storage system safety analysis reports, the canister drops can be sustained without breaching the confinement boundary.

2. Radioactive Material Handling Accident (Non-Fuel Related)

The limiting non-fuel related event involves the release of radioactive material from either a liquid radioactivity storage tank or from a concentrated source, such as filters, resins, and open shipping containers (as discussed in NUREG-0586, Appendix I).

For liquid releases, the SONGS UFSAR states that there are no credible accidents that could exceed 10 CFR 20 limits.

For a concentrated solid source, the evaluated initiator for these events is a postulated fire.

During SONGS decommissioning activities, after all spent fuel has been moved to the ISFSI, there would be no concentrated source of radioactive materials whose release to the environment could exceed two times the ODCM limit at the EAB (2 x 1500 mrem/year).\

During decontamination and dismantlement activities, administrative controls would be applied to the handling of open containers or other packages containing filters, resins, and other dispersable materials generated during decommissioning activities such that a release Page 8

EVALUATION OF THE PROPOSED AMENDMENT ISFSl-Only Emergency PLAN (IOEP) and Emergency Action Level (EAL) Scheme to the environment from concentrated sources of these radioactive materials would not exceed two times the ODCM limit at the EAB.

3. Accidents Initiated in External Events The effects of external events, such as aircraft crashes, fires, floods, wind (including tornados), earthquakes, lightning, and physical security breaches on the ISFSI remain unchanged from the effects that were considered under the existing emergency plan.

Externally initiated events are addressed by the proposed EALs.

In summary, there continues to be a low likelihood of any postulated event resulting in radiological releases requiring offsite protective measures, and there is no credible radioactive material event (non-fuel related) resulting in radiological releases requiring declaration of an emergency.

3.3 ISFSl-Only Emergency Plan The SONGS ISFSl-Only Emergency Plan (IOEP) is provided in Enclosure 1 to this submittal for NRC review and approval. This proposed emergency plan is associated with EALs for events related to the ISFSI. The IOEP addresses the applicable regulations stipulated in 10 CFR 50.47, "Emergency Plans" (as exempted), 10 CFR 50, Appendix E, "Emergency Planning and Preparedness for Production and Utilization Facilities" (as exempted), and 10 CFR 72.32, "Emergency Plan," and is consistent with the applicable guidelines established in NUREG-0654/FEMA-REP-1, Revision 1, "Criteria for Preparation and Evaluation of Radiological Emergency Response Plans and Preparedness in Support of Nuclear Power Plants."

The IOEP describes the station's plan for responding to emergencies that may arise at SONGS while all spent nuclear fuel is in dry storage within an ISFSI. Currently, irradiated fuel is stored both in the ISFSI and in the spent fuel pool (SFP). After all fuel at SONGS is in dry storage within the ISFSI, the number and severity of potential radiological accidents is .significantly less than when fuel was also stored in the SFP.

As provided in the ISFSI storage system Final Safety Analysis Reports (FSARs), the analyses of the potential radiological impacts of postulated off-normal, natural phenomenon, and accident

. events in an ISFSl-only condition indicate that any releases beyond the Exclusion Area Boundary (EAB) would result in a dose to the public below the radiation limits established in 10 CFR 72.106(b). Areas where exposure levels could potentially warrant pre-planned response measures are generally limited to the ISFSI pad and nearby vicinity; for this reason radiological emergency planning is focused in this area.

The EAB is the area surrounding the ISFSI in which SCE has the authority to determine all activities including exclusion or removal of personnel and property from the area. The analyses of the radiological impact of potential accidents at the ISFSI conclude that any releases beyond the EAB are expected to be less than the EPA PAGs.

Based on the reduced number and consequences of potential radiological events at SONGS with all spent nuclear fuel in dry storage within the ISFSI, there will continue to be no need for Page 9

EVALUATION OF THE PROPOSED AMENDMENT ISFSl-Only Emergency PLAN (IOEP) and Emergency Action Level (EAL) Scheme offsite emergency response plans for the protection of the public beyond the EAB. Additionally, the scope of the onsite emergency preparedness organization and corresponding requirements in the emergency plan may be reduced without an undue risk to the public health and safety.

The analysis of the potential radiological impact of an accident in a condition with all irradiated fuel stored in the ISFSI indicates that any releases beyond the EAB are below the EPA PAG exposure levels, as detailed in Reference 6. Exposure levels, which warrant pre-planned response measures, are limited to onsite areas. For this reason, radiological emergency planning is focused onsite.

3.4 ISFSl-Only Emergency Action Levels provides the site-specific EAL technical bases document, which contains the proposed SONGS ISFSl-Only Emergency Action Level (IOEAL) scheme for NRC review and approval. The current SONGS EAL scheme was approved by NRC on June 5, 2015 (Reference 7). The new ISFSI EAL scheme is to be implemented by the SONGS ISFSl-Only Emergency Plan (provided in Enclosure 1).

Deletions from the currently approved EAL scheme are listed in Section 2.2, "Elimination of Spent Fuel Pool Initiating Events and EALs," Table 1, "Emergency Plan Initiating Conditions Being Deleted," above.

Operating Modes and Applicability The proposed EALs are only applicable after the final spent nuclear fuel assembly has been transferred out of the spent fuel pool and placed in storage within the ISFSI.

State and Local Government Review of Proposed Changes State and local emergency management officials are advised of EAL changes that are implemented. Following NRC approval and prior to implementation, SCE will provide an overview of the new classification scheme to State and local emergency management officials in accordance with 10 CFR Part 50, Appendix E, Section IV.B.1.

SUMMARY

By letters dated June 28, 2013 (Reference 1) and July 22, 2013 (Reference 2), SCE submitted a certification of permanent removal of fuel from the reactor vessels for SONGS Units 2 and 3, pursuant to 10 CFR 50.82(a)(1 )(ii). Consequently, as specified in 10 CFR 50.82(a)(2), the 10 CFR Part 50 license for SONGS no longer authorizes operation of the reactor or emplacement or retention of fuel into the reactor vessel. The Post-Shutdown Decommissioning Activities Report (PSDAR) for SONGS dated September 23, 2014 (Reference 3), documented that SCE expects to have all spent fuel transferred to the Independent Spent Fuel Storage Installation (ISFSI) in 2019. SONGS Unit 1 spent fuel has previously been removed from the Unit 1 spent fuel pool and is now in dry storage. To reflect the reduced scope of potential radiological Page 10

EVALUATION OF THE PROPOSED AMENDMENT ISFSl-Only Emergency PLAN CIOEP) and Emergency Action Level (EAL) Scheme accidents with spent fuel in dry cask storage within the ISFSI, SCE proposes a new EAL scheme and corresponding emergency plan changes.

This proposed amendment would revise both the emergency plan and the EAL scheme appropriate for the condition of the station wherein all spent nuclear fuel is in dry storage within the ISFSI. The new emergency plan and EAL scheme are being submitted to the NRC for approval prior to implementation, as required under Section IV.8.2 of Appendix E to 10 CFR Part 50. Additionally, 10 CFR 50.54( q)( 4) and 10 CFR 72.44(f) require that the proposed changes receive prior approval by the NRC because they are considered to reduce the effectiveness of the plan.

The proposed emergency plan does not meet all standards of 10 CFR 50.47(b) and requirements of 10 CFR 50, Appendix E. However, SCE was granted exemptions from portions of 10 CFR 50.47(b), 10 CFR 50.47(c)(2), and 10 CFR 50, Appendix E, Section IV, by letter dated June 4, 2014 (Reference 4). The basis for these exemptions has not changed and remains in effect for the proposed emergency plan changes. With the granted exemptions, the emergency plan, as revised, will continue to meet the remaining applicable requirements in 10 CFR 50, Appendix E and the planning standards of§ 50.47(b).

5.0 REGULATORY ANALYSIS

5.1 No Significant Hazards Consideration Pursuant to 10 CFR 50.90, Southern California Edison (SCE) is submitting Amendment Applications 226, 273, and 258 for San Onofre Nuclear Generating Station (SONGS) Units 1, 2 and 3, respectively. The proposed amendments would revise the Permanently Defueled Emergency Plan (PDEP) into an ISFSl-Only Emergency Plan (IOEP) and revise the Emergency Action Level (EAL) into an ISFl-Only EAL (IOEAL) scheme. The proposed changes are being submitted to the NRC for approval prior to implementation, as required under 10 CFR 50.54(q)(4), 10 CFR 50, Appendix E, Section IV.8.2, and 10 CFR 72.44(f).

By letters dated June 28, 2013 (Reference 1) and July 22, 2013 (Reference 2), SCE submitted a certification of permanent removal of fuel from the reactor vessels for SONGS Units 2 and 3, pursuant to 10 CFR 50.82(a)(1)(ii). Consequently, as specified in 10 CFR 50.82(a)(2), the 10 CFR Part 50 license for SONGS no longer authorizes operation of the reactor or emplacement or retention of fuel into the reactor vessel. The Post-Shutdown Decommissioning Activities Report (PSDAR) for SONGS dated September 23, 2014 (Reference 3), documented that SCE expects to have all spent fuel transferred to the Independent Spent Fuel Storage Installation (ISFSI) in 2019. SONGS Unit 1 spent fuel has previously been removed from the Unit 1 spent fuel pool and is now in dry storage. To reflect the reduced scope of potential radiological accidents with spent fuel in dry cask storage within the ISFSI, SCE proposes a new EAL scheme and corresponding emergency plan changes.

SCE has evaluated the proposed amendments to determine if a significant hazards consideration is involved by focusing on the three standards set forth in 10 CFR 50.92, "Issuance of Amendment," as discussed below:

Page 11

EVALUATION OF THE PROPOSED AMENDMENT ISFSl-Only Emergency PLAN {IOEP) and Emergency Action Level (EAL) Scheme

1. Does the proposed amendment involve a significant increase in the probability or consequences of an accident previously evaluated?

Response: No The proposed amendments would modify the SONGS Units 1, 2 and 3 licenses by revising the emergency plan and revising the EAL scheme. The SONGS units have permanently ceased operation and are permanently defueled. The proposed amendments are conditioned on all spent nuclear fuel being removed from wet storage in the spent fuel pools and placed in dry storage within an ISFSI. Occurrence of postulated accidents associated with spent fuel stored in a spent fuel pool is no longer credible in a spent fuel pool devoid of such fuel. The proposed amendments have no effect on plant systems, structures, and components (SSCs) and no effect on the capaQility of any plant SSC to perform its design function. The proposed amendments would not increase the likelihood of the malfunction of any plant SSC. The proposed amendments would have no effect on any of the previously evaluated accidents in the SONGS Updated Final Safety Analysis Report (UFSAR).

Since SONGS has permanently ceased operation, the generation of fission products has ceased and the remaining source term continues to decay. This continues to significantly reduce the consequences of previously postulated accidents. Therefore, the proposed amendments do not involve a significant increase in the consequences of a previously evaluated accident.

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

Response: No The proposed amendments constitute a revision of the emergency planning function commensurate with the ongoing and anticipated reduction in radiological source term at SONGS.

The proposed amendments do not involve a physical alteration of the plant. No new or different types of equipment will be installed and there are no physical modifications to existing equipment as a result of the proposed amendments. Similarly, the proposed amendments would not physically change any SSCs involved in the mitigation of any postulated accidents. Thus, no new initiators or precursors of a new or different kind of accident are created. Furthermore, the proposed amendments do not create the possibility of a new failure mode associated with any equipment or personnel failures. The credible events for the ISFSI remain unchanged.

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

Page 12

EVALUATION OF THE PROPOSED AMENDMENT ISFSl-Only Emergency PLAN (IOEPl and Emergency Action Level (EAL) Scheme

3. Does the proposed amendment involve a significant reduction in a margin of safety?

Response: No Because the 10 CFR Part 50 licenses for SONGS no longer authorize operation of the reactors or emplacement or retention of fuel into the reactor vessels, as specified in 10 CFR 50.82(a)(2), the occurrence of postulated accidents associated with reactor operation is no longer credible. With all nuclear spent fuel transferred out of wet storage from the spent fuel pools and placed in dry storage within the ISFSI, a fuel handling accident is no longer credible. There are no longer credible events that would result in any releases beyond the EAB exceeding the EPA PAG exposure levels, as detailed in the EPA's "Protective Action Guide and Planning Guidance for Radiological Incidents," Draft for Interim Use and Public Comment dated March 2013 (PAG Manual).

The proposed amendments do not involve a change in the plant's design, configuration, or operation. The proposed amendments do not affect either the way in which the plant structures, systems, and components perform their safety function or their design margins.

Because there is no change to the physical design of the plant, there is no change to any of these margins.

Therefore, the proposed amendments do not involve a significant reduction in a margin of safety.

• Based on the above, SCE concludes that the proposed amendments present no significant hazards consideration under the standards set forth in 10 CFR 50.92(c), and, accordingly, a finding of "no significant hazards consideration" is justified.

5.2 Applicable Regulatory Requirements/Criteria The regulatory requirements, as exempted, are discussed below.

Title 10 of the Code of Federal Regulations (10 CFR), Section 50.47, "Emergency plans," sets forth emergency plan requirements for nuclear power plant facilities. The regulations in 10 CFR 50.47(a)(1 )(i) state, in part, "No initial operating license for a nuclear power reactor will be issued unless a finding is made by the NRC that there is reasonable assurance that adequate protective measures can and will be taken in the event 'of a radiological emergency."

Section 50.47(b) establishes the standards that emergency response plans must meet for NRC staff to make a positive finding that there is reasonable assurance that the licensee can and will take adequate protective measures in the event of a radiological emergency.

• Planning Standard (1) of Section 50.47(b) states, in part: "[E]ach principal response organization has staff to respond and to augment its initial response on a continuous basis."

• Page 13

EVALUATION OF THE PROPOSED AMENDMENT ISFSl-Only Emergency PLAN (IOEP) and Emergency Action Level (EAL) Scheme

• Planning Standard (2) of Section 50.47(b) states, in part: "On-shift facility licensee responsibilities 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 .... "

• Planning Standard (4) of Section 50.47(b) requires that a licensee's emergency response plan contain the following: "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."

• Planning Standard (8) of Section 50.47(b) states, in part: "Adequate emergency facilities and equipment to support the emergency response are provided and maintained."

10 CFR 50.54(q)(4) specifies the process for revising emergency plans where the changes reduce the effectiveness ofthe plan. This regulation states the following:

"The changes to a licensee's emergency plan that reduce the effectiveness of the plan as defined in paragraph (q)(1 )(iv) of this section may not be implemented without prior approval by the NRC."

Section IV.A of Appendix E, "Emergency Planning and Preparedness for Production and Utilization Facilities," to 10 CFR Part 50, states, in part: "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 .... "

Section IV.C.1 of Appendix E requires each emergency plan to define the emergency classification levels that determine the extent of the participation of the emergency response organization.

Section IV.E of Appendix Estates, in part: "Adequate provisions shall be made and described for emergency facilities and equipment. ... "

As proscribed in 10 CFR 72.13, "Applicability", the applicable emergency plan requirements for an Independent Spent Fuel Storage Installation associated with a general license are specified in 10 CFR 72.32(c) and (d).

The proposed emergency plan continues to rely on previously granted exemptions from certain emergency planning requirements (Reference 4) as the basis for these exemptions has not changed and remains in effect.

In November 2012, NEI published NEI 99-01, Revision 6 (Reference 8). NRC endorsed NEI 99-01, Revision 6, by letter dated March 28, 2013 (Reference 10). The changes being requested herein are based on Revision 6 to NEI 99-01. The proposed changes are conservatively being considered as a change to the EAL scheme development methodology. Pursuant to 10 CFR Part 50, Appendix E, Section IV.B.2, a revision to an entire EAL scheme must be approved by the NRC before implementation. '

Page 14 c

EVALUATION OF THE PROPOSED AMENDMENT ISFSl-Only Emergency PLAN (IOEP) and Emergency Action Level (EAL) Scheme 5.3 Precedent Similar changes to emergency plans and associated emergency action levels for plants that have transitioned to ISFSl-only status were approved by NRG for the La Crosse Boiling Water Reactor facility on September 8, 2014 (Reference 11) and for the Zion facility on May 14, 2015 (Reference 12).

• 5.4 Conclusion Based on the considerations discussed above, (1) there is reasonable assurance that the health and safety of the public will not be endangered by operation in the proposed manner, (2) such activities will be conducted in compliance with the Commission's regulations, and (3) the issuance of the amendment will not be inimical to the common defense and security or to the health and safety of the public.

6.0 ENVIRONMENTAL CONSIDERATION

A review has determined that the proposed amendments would change a requirement with respect to installation or use of a facility component located within the restricted area, as defined in 10 CFR 20, or would change an inspection or surveillance requirement. However, the proposed amendments do not involve (i) a significant hazards consideration, (ii) a significant change in the types or significant increase in the amounts of any effluent that may be released offsite, or (iii) a significant increase in individual or cumulative occupational radiation exposure.

Accordingly, the proposed amendment meets the eligibility criterion for categorical exclusion set forth in 10 CFR 51.22(c)(9). Therefore, pursuant to 10 CFR 51.22(b), no environmental impact statement or environmental assessment need be prepared in connection with the proposed.

amendments.

IOEP-1 SONGS ISFSl-Only Emergency Plan PARTI

1.0 INTRODUCTION

The San Onofre Nuclear Generating Station (SONGS) is owned by Southern California Edison (SCE), San Diego Gas and Electric (SDG&E) and the cities of Anaheim and Riverside, California.

SCE is authorized to act as agent for the co-participants and has exclusive responsibility for the operation of the facility.

The SONGS INDEPENDENT SPENT FUEL STORAGE INSTALLATION (ISFSI) Only Emergency Plan (IOEP) describes the plan for responding to emergencies that may arise at the station's ISFSI.

In this condition, no reactor operations can take place and all irradiated fuel is removed from the Spent Fuel Pools (SFPs). This IOEP addresses the risks associated with SONGS' ISFSl-Only conditions.

As provided in the ISFSI storage system Final Safety Analysis Reports (FSARs), the analyses of the potential radiological impacts of postulated off-normal, natural phenomenon, and accident events in an ISFSl-Only condition indicates that any releases beyond the EXCLUSION AREA BOUNDARY (EAB) would result in a DOSE to the public below the radiation limits established in 10 CFR 72.106(b). Areas where exposure levels could potentially warrant pre-planned response measures are generally limited to the ISFSI pad and nearby vicinity; for this reason radiological emergency planning is focused on this area.

1.1 PURPOSE The purpose of the IOEP is to assure an adequate level of preparedness to cope with a spectrum of emergencies. This Plan integrates the necessary elements to provide effective emergency response considering cooperation and coordination of organizations expected to respond to emergencies.

1.2 SCOPE The SONGS IOEP is developed to respond to potential radiological emergencies at the SONGS ISFSI. Because there are no postulated off-normal, natural phenomenon, or accident events that would result in OFFSITE DOSE consequences that are large enough to require OFFSITE emergency planning, the overall scope of this Plan delineates the actions necessary to safeguard ONSITE personnel. The concepts presented in this Plan address the applicable regulations stipulated in 10 CFR 50.47, "Emergency Plans" and 10 CFR 50, Appendix E, "Emergency Planning and Preparedness for Production and Utilization Facilities". The Plan is consistent with the applicable guidelines established in NUREG-0654/FEMA-REP-1, Revision 1, "Criteria for Preparation and Evaluation of Radiological Emergency Response Plans and Preparedness in Support of Nuclear Power Plants" and NEI 99-01, "Development of Emergency Action Levels for Non-Passive Reactors" Rev. 6.

Exemptions from selected portions of 10 CFR 50.47 and 10 CFR 50 Appendix E for SONGS were granted by the Nuclear Regulatory Commission (NRC) on June 4, 2015 (ADAMS Accession Number: ML15082A204).

The IOEP revision 0 was approved per NRC Safety Evaluation dated [insert date prior to issuing].

1 Revision O

IOEP-1 SONGS ISFSl-Only Emergency Plan 2.0 DISCUSSION 2.1 OVERVIEW OF ISFSI ONLY EMERGENCY PLAN (IOEP)

In the event of an emergency at the SONGS ISFSI, actions are required to identify and assess the nature of the emergency and to respond in a manner that protects the health and safety of the public and ONSITE personnel.

This Plan describes the organization and responsibilities for implementing emergency measures. It describes interfaces with OFFSITE government agencies (Federal, State and local) which may be notified in the event of an emergency, and may provide assistance. Fire, rescue and ambulance services are provided by the United States Marine Corps Camp Pendleton Fire Department (USMC CPFD).Law enforcement services are provided by the Federal Bureau of Investigation (FBI) and local public entities. Medical services are provided by Mission Hospital Regional Medical Center in Mission Viejo, California.

Because there are no postulated events that would result in OFFSITE DOSE consequences that are large enough to require OFFSITE emergency planning, emergencies are divided into two emergency CLASSIFICATION levels: UNUSUAL EVENT (UE) and ALERT.

SONGS is responsible for planning and implementing emergency measures associated with the SONGS ISFSI. This Plan is provided to meet this responsibility. To carry out specific emergency measures discussed in this Plan, detailed implementing procedures are established and maintained.

In addition to the description of activities and steps that can be implemented during a potential emergency, this Plan also provides a general description of the steps taken to recover from an emergency situation. It also describes the training, drills, exercises, planning, and coordination appropriate to maintain an adequate level of EMERGENCY PREPAREDNESS.

2.2 FACILITY DESCRIPTION SONGS has permanently ceased power operations and all Units 2 and 3 irradiated fuel has been removed from the SFPs and placed into dry storage within the SONGS ISFSI.

SONGS Unit 1 has been permanently shut down since 1993 and is in the decommissioning phase.

Above-ground structures have been dismantled. Unit 1 fuel is stored in the SONGS ISFSI and in the GE-Hitachi Morris facility.

By letter dated June 12, 2013, SCE certified its intention to permanently cease power operations at SONGS Units 2 and 3 as of June 7, 2013, pursuant to 10 CFR 50.82(a)(1)(i). By letters dated June 28, 2013 and July 22, 2013, SCE certified permanent removal offuel from the Unit 2 and Unit 3 reactor vessels, pursuant to 10 CFR 50.82(a)(1 )(ii). The 10 CFR 50 licenses for SONGS Units 2 and 3 no longer authorize operation of the reactors, or emplacement or retention of fuel into the reactor vessels, as specified in 10 CFR 50.82(a)(2).

The San Onofre ISFSI is located on the coast of southern California in San Diego County, near the border with Orange County. The site is located entirely within the boundaries of the United States Marine Corps Base, Camp Pendleton, California. There is public access between the beaches north and south of the station. Interstate Highway 5 and the Atchison, Topeka, and Santa Fe Railway pass within 1000 feet of the station.

IOEP-1 SONGS ISFSl-Only Emergency Plan 2.3

SUMMARY

OF EMERGENCY ACTIONS This Plan is activated by the ISFSI Shift Supervisor, who assumes the position of EMERGENCY DIRECTOR (ED) upon DECLARATION of an emergency based upon CLASSIFICATION of an event according to the EMERGENCY ACTION LEVEL (EAL) criteria. The emergency measures described in the subsequent sections and implementing procedures are implemented in accordance with the CLASSIFICATION and nature of the emergency at the direction of the ED. Regulatory authorities and OFFSITE support organizations are notified in accordance with this Plan. The ED has authority and responsibility for control and mitigation of the emergency, including emergency response resources, coordination of radiological ASSESSMENT ACTIVITIES, recovery implementation, and coordination of emergency response activities. The following sections of this Plan describe the detailed plans and actions of the SONGS EMERGENCY RESPONSE ORGANIZATION (ERO), including interfaces with OFFSITE support organizations.

IOEP-1 SONGS ISFSl-Only Emergency Plan 4.0 DEFINITIONS AND ABBREVIATIONS 4.1 DEFINITIONS This section provides definitions that are used in this document. Terms capitalized in the text of the definitions indicate that they are defined elsewhere in this section.

Accident Assessment - Accident assessment consists of a variety of actions taken to determine the nature, effects and severity of an accident.

Accountability - A procedural or discretionary PROTECTIVE ACTION taken for all persons within the ISFSI PROTECTED AREA, which involves the gathering of personnel into pre-designated areas, and the subsequent verification that the location of these personnel is known.

Alert - Events are in progress or have occurred which involve an actual or potential substantial degradation of the level of safety of the ISFSI or a security event that involves probable life threatening risk to station personnel or damage to ISFSI equipment because of HOSTILE ACTION.

Any releases are expected to be limited to small fractions of the EPA PROTECTIVE ACTION Guideline exposure levels.

IOEP-1 SONGS ISFSl-Only Emergency Plan 4.0 EMERGENCY CLASSIFICATION SYSTEM Planning Standard 50.47(b)(4) (as exempted in Reference 17) -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.

SONGS utilizes NEI 99-01, Revision 6, "Development of Emergency Action Levels for Non- Passive Reactors" as its basis for classifying emergencies. The CLASSIFICATION system referenced in NEI 99-01, Rev. 6 has been endorsed by the NRC and offers a standard method for classifying emergencies. EALs are addressed in site procedures and the ISFSl-Only Emergency Plan*

Emergency Action Level Technical Bases Manual (IOEP-2).

This Plan addresses two (2) CLASSIFICATIONS of emergencies (UNUSUAL EVENT and ALERT),

which represent a hierarchy of emergencies based on potential accidents that could occur at the SONGS ISFSI. Once indications are available that an EAL is met, the event is assessed and classified, and the corresponding emergency CLASSIFICATION level is promptly declared as soon as possible.

4.1 UNUSUAL EVENT Events are in progress or have occurred which indicate a potential degradation of the level of safety of the SONGS ISFSI or indicate a security threat to facility protection has been initiated. No release of radioactive material requiring OFFSITE response or monitoring are expected. State and LOCAL GOVERNMENT AGENCIES, Marine Corps Base Camp Pendleton and the NRC are notified of an UNUSUAL EVENT.

The purpose of the UNUSUAL EVENT CLASSIFICATION is to bring the on-shift staff to a state of readiness and to provide for systematic handling of event information and its related decision making.

4.2 ALERT Events are in progress or have occurred which involve an actual or potential substantial degradation of the level of safety of the SONGS ISFSI or a security event that involves probable life threatening risk to site personnel or damage to ISFSI equipment because of HOSTILE ACTION.

Any releases are expected to be limited to small fractions of the EPA PAG exposure levels.

As in the case of the UNUSUAL EVENT, the ALERT CLASSIFICATION includes emergency situations which are not expected to threaten the public, but for which notification of the State and LOCAL GOVERNMENT AGENCIES, Marine Corps Base Camp Pendleton and the NRC is required.

The ASSESSMENT ACTIVITIES required to evaluate a particular emergency depend on the specific nature and CLASSIFICATION of the emergency. The ED is responsible for the initial measurement of ISFSI DOSE RATES after an off-normal, natural phenomena, or accident event.

The EALs identify the parameter value to determine the emergency condition. CLASSIFICATION of events is performed by the ED in accordance with the EAL scheme.

If the measured ISFSI DOSE RATES exceed the EAL threshold, the ED then performs a radioactive release assessment in the vicinity of the affected storage module or cask. After completing the assessment, the ED contacts the Resource Manager to assist in interpreting the radioactive release assessment results.

Notification of a radiological release assessment is in accordance with Section 5.0.

24 Revision O

IOEP-1 SONGS ISFSl-Only Emergency Plan 10.0 PROTECTIVE ACTIONS Planning Standard 50.47(b)(10) (as exempted in Reference 17)-A range of protective actions has been developed for emergency workers and the public.

PROTECTIVE ACTIONS for ONSITE personnel are provided for their health and safety.

Implementation guidelines for ONSITE PROTECTIVE ACTIONS are provided in EPIPs.

Additionally, the EPIPs provide for a range of PROTECTIVE ACTIONS (e.g. relocation of personnel and personnel take cover) to protect ONSITE personnel during HOSTILE ACTIONS.

ACCOUNTABILITY ACCOUNTABILITY should be considered and used as a PROTECTIVE ACTION whenever a site wide risk to health or safety exists and prudence dictates. If personnel ACCOUNTABILITY is required, at the direction of the ED all individuals at the site (including employees without emergency assignments, visitors, and contractor personnel) shall be notified of the emergency.

ACCOUNTABILITY of all personnel inside the ISFSI PROTECTED AREA (PA) should be accomplished within 60 minutes after emergency DECLARATION and maintained thereafter. If personnel are unaccounted for, teams shall be dispatched to locate the personnel.

Non-ESSENTIAL PERSONNEL located outside of the ISFSI PA but within the SITE BOUNDARY will be directed to report to an assembly area or exit the site, as appropriate. The ED is responsible for controlling access to the site when the IOEP is activated.

The means for controlling radiological exposures shall include exposure guidelines consistent with EPA Emergency Worker and Lifesaving Activity Protective Action Guides.

SONGS maintains a radiological exposure control program to assure that protection against radiological exposure, as set forth in 10 CFR Part 20 is provided. This program is implemented through the "Radiological Protection Standard" which covers both normal and emergency radiation protection measures.

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.

Exposure Guidelines During an emergency, DOSES above normal occupational radiation exposure limits may be authorized by the ED for activities such as saving a life, preservation of valuable equipment, or controlling exposure. Table 11-1 contains the guidelines for emergency exposure criteria, which is consistent with the EPA's, "Protective Action Guide and Planning Guidance for Radiological Incidents," Table 2-2, "Response Worker Guidelines".

• Radiation Protection The purpose of a Radiation Protection Program is to assure that radiation DOSES received by personnel are kept as low as reasonably achievable and do not exceed the prescribed limits for both normal and emergency conditions. The established measures to provide this assurance include access control, personnel monitoring, and contamination control.

Access Control During a declared emergency, radiological surveys of the ISFSI area will be performed to determine the actual extent of the radiological conditions. As necessary, the ED will ensure RCAs and access controls are established to prevent personnel from entering the area. Recovery and CORRECTIVE ACTIONS will be planned and executed in a manner that minimizes exposure to personnel.

Contaminated areas are isolated with appropriate radiological protection and access control.

Personnel leaving contaminated areas are monitored for radioactive contamination. Supplies, instruments, and equipment that are in contaminated areas or have been brought into contaminated areas will be monitored prior to removal.

Restricted areas and contaminated items will be returned to normal use when contamination levels have been returned to acceptable levels. Contamination control criteria for returning areas and items to normal use are contained in the station procedures.

IOEP-1 SONGS ISFSl-Only Emergency Plan Personnel Exposure Monitoring Personal dosimeters are utilized to monitor the exposure of personnel during normal or emergency conditions. Adequate supplies of dosimeters are maintained for use during an emergency.

Procedures describe in detail the types of personal dosimeter devices, the manner in which they are to be used, who is to wear them, and how they are tb be cared for.

Emergency worker DOSE records are maintained in accordance with station procedures Contamination Control Various contamination control measures are utilized. These include access control measures and means for the DECONTAMINATION of personnel, areas, and equipment. These activities are addressed in facility procedures and are briefly described below. All personnel are monitored for radioactive contamination prior to leaving the RCA. During normal or emergency conditions, contamination should be removed from any part of a person's body prior to their leaving the RCA.

All personnel DECONTAMINATION, even during an emergency, will be performed under the supervision of personnel trained in radiological monitoring and assessment and in accordance with established procedures.

Portable contamination monitoring instruments are available to frisk personnel for potential contamination.

Documentation of surveys, contamination, and DECONTAMINATION activities shall be maintained in accordance with station procedures.

SCE has established general plans described in the following sections to conduct recovery from potential emergencies at the SONGS ISFSI. The recovery organization will be based on the normal SONGS organization and would function with the senior management position being responsible for site activities.

Emergency Termination and Notification Termination of an emergency status is the responsibility of the ED. The ED is also responsible for providing notification of the emergency termination and initiation of Recovery operations to the NRC, State and LOCAL GOVERNMENT AGENCIES and Marine Corps Base Camp Pendleton, the SONGS ERO and other organizations that may be providing ONSITE support.

Recovery Operations Recovery operations begin immediately following emergency termination and will address the specific emergency circumstances. Recovery planning includes equipment to be repaired or replaced, licensing implications, special training requirements, OFFSITE support, and determination of causes and consequences. Site procedures addressing Recovery operations provide an outline for a short term Recovery plan.

The senior management position shall be responsible for the development and implementation of the Recovery plan and shall provide for detailed monitoring of the implementation and status reporting. The senior management position also has the authority to revise or halt activities as circumstances dictate.

The ISFSI recovery will be terminated by the SONGS senior management position after the ISFSI has been returned to a stable condition.

Exercise and Drill SONGS conducts a BIENNIAL Exercise to test the adequacy of timing and content of implementing procedures and methods; to test emergency equipment and communication networks; and to ensure that emergency personnel are familiar with their duties. Each exercise will be evaluated by station evaluators and possibly Federal evaluators. SONGS will invite Federal, State, and LOCAL GOVERNMENT AGENCIES to participate or observe scheduled exercises upon request.

For alternating years, an INTEGRATED DRILL is conducted for the purpose of testing, developing, and maintaining the proficiency of emergency responders. BIENNIAL Exercises and alternate year INTEGRATED DRILLS will allow the ERO to demonstrate the following principal functional areas:

Exercise and drill scenarios are developed to provide reasonable assurance that anticipatory responses will not result from preconditioning of participants. Exercise and drill scenarios, as appropriate, emphasize coordination among ONSITE and OFFSITE response organizations.

Exercise and drills allow free play for decision making. The scenarios for use in exercises and drills include, at a minimum, the following:

• The basic objective(s) of each drill and exercise and appropriate evaluation criteria;

• The date(s), time period, place(s), and participating organizations;

• The simulated events;

• A time schedule of real and simulated initiating events;

• A narrative summary describing the conduct of the exercises or drills to include such things as simulated casualties, OFFSITE fire department assistance, rescue of personnel, use of protective clothing; and,

• A description of the arrangements for and advance materials to be provided to official observers.

The scenario should be varied from year to year such that all major elements of the plans and preparedness organizations are tested.

30 Revision O

IOEP-1 SONGS ISFSl-Only Emergency Plan Equipment and Proficiency Drills Drills are conducted to provide supervised instruction, training and practice opportunities for ERO members. Drills may be performed as part of the BIENNIAL exercise, INTEGRATED DRILL or as an independent drill. A drill may be a component of an exercise. Drills are supervised and evaluated by qualified personnel. Drills are conducted, in addition to the exercise at the frequencies indicated below:

Communication Drills A communications drill with State and LOCAL GOVERNMENT AGENCIES is conducted ANNUALLY. A communications drill with NRG Headquarters is conducted ANNUALLY.

Communication drills include the aspect of understanding the content of messages.

Fire Drills A fire drill is conducted in accordance with SONGS Fire Protection Program.

The OFFSITE portions of the medical drill may be performed as part of the required BIENNIAL exercise or INTEGRATED DRILL.

Radiation Protection Drills A Radiation Protection drill is conducted ANNUALLY.

Augmentation Drills An unannounced augmentation drill is conducted ANNUALLY. This drill involves implementation of the ERO callout system procedure and documentation of the estimated response time for each responder. This drill demonstrates the capability to augment the ED after an emergency is declared.

Critique and Evaluation Critiques shall be scheduled at the conclusion of each exercise or alternate year INTEGRATED DRILL to evaluate the performance of the organization. The ability of EMERGENCY RESPONSE PERSONNEL to self-evaluate weaknesses and identify areas for improvement is the key to successful exercise I drill conduct.

Exercise and drill objectives are evaluated against measurable demonstration criteria. Following the conclusion of each exercise or drill, a critique, including participants and evaluators, is conducted to evaluate the ability of the ERO to implement the IOEP and its implementing procedures.

Official observers from the NRG should observe, evaluate, and critique the required exercises.

A formal evaluation in the form of a written critique report is prepared following an exercise or drill involving the evaluation of designated objectives. The report evaluates and documents the ability of the ERO to respond to a simulated emergency situation. The report will also contain reference to CORRECTIVE ACTION documents and recommendations.

IOEP-2 EAL Technical Bases Manual

1.0 INTRODUCTION

1.1 PURPOSE This document contains the Nuclear Regulatory Commission (NRC) approved set of INITIATING CONDITIONS (ICs), their associated EMERGENCY ACTION LEVEL (EAL) thresholds, and their site-specific technical bases, for the San Onofre Nuclear Generating Station (SONGS)

INDEPENDENT SPENT FUEL STORAGE INSTALLATION (ISFSI), using the EAL development methodology found in NEI 99-01 Revision 6.

Any changes to this document will be made in accordance with the requirements of 10 CFR 50.54(q) and 10 CFR 72.44(f).

Personnel responsible for emergency classification and declaration may use this document as a technical reference and an aid in EAL interpretation. 1 The primary tool for determining the EMERGENCY CLASSIFICATION LEVEL is the EAL Matrix Table in this manual, also available on form EP(123) EAL, Emergency Action Levels. The user of the EAL Matrix Table may (but is not required to) consult the Emergency Action Level Technical Bases Manual in order to obtain additional information concerning the EALs being considered for classification of an emergency.

This document is also used to facilitate review of any proposed changes to the SONGS ISFSl-Only EALs.

The SONGS ISFSI is essentially an interim spent fuel storage facility where the spent fuel is surrounded by inert gas inside a container called a canister. The canisters used at SONGS are stainless steel cylinders that are welded closed. The fuel is cooled by natural airflow around the canister. The fuel was moved to dry storage after several years in spent fuel pools, so the heat given off by the fuel has significantly decreased. Each canister is surrounded by additional steel, concrete, or other material to provide physical protection, structural integrity, and additional radiation shielding to workers and members of the public. These primary functions of the ISFSI are the focus of the ISFSl-Only ICs and EALs.

SCE was granted exemptions from portions of 10 CFR 50.47(b), 10 CFR 50.47(c)(2), and 10 CFR 50 Appendix E, Section IV. The basis for these exemptions has not changed and remains in effect for the ISFSl-Only Emergency Plan (IOEP). The changes to this Technical Bases Manual reflect the lowered radiological source term and risks associated with ISFSI storage relative to reactor at power operation or storage in spent fuel pools. Source terms and accident analyses associated with design basis accidents are documented in the dry storage systems' Final Safety Analysis Reports (FSARs).

With regard to event recognition and classification, regulations specific to the declaration of emergencies are provided in planning standard 10 CFR 50.47(b)(4), 10 CFR 50 Appendix E.IV.B, and 10 CFR 72.32(a)(3).

1 Emergency event 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. Use of this document for assistance is not intended to delay event declaration.

1 Revision O

IOEP-2 EAL Technical Bases Manual The NRC, by letter to Nuclear Energy Institute (NEI) dated 03/28/13(ML12346A463), documented its review of the draft version of NEI 99-01, Revision 6, dated November 2012 (ML12326A805), and found it acceptable for use by licensees seeking to upgrade their EMERGENCY ACTION LEVELS (EALs) in accordance with 10 CFR 50 Appendix E. The regulatory and technical analysis for this endorsement can be retrieved through ADAMS Accession No. ML13008A736.

1.2 EMERGENCY CLASSIFICATION LEVELS (ECLS)

As defined in NUREG-0654/FEMA-REP-1, nuclear power plant emergencies are separated into four ECLs:

• UNUSUAL EVENT (UE)

• ALERT

• Site Area Emergency

• General Emergency The ECLs are escalated from least severe to most severe according to the relative threat to the health and safety of the public and emergency workers. An ECL is determined to be met by identifying abnormal conditions and then comparing them to ICs through EAL threshold values as discussed below. When multiple EALs are met, event declaration is based in the highest ECL reached.

The ISFSI Only ICs and EALs within this document use the two lower of the four ECLs. The source terms and release motive forces associated with an ISFSI are not sufficient to require declaration of a Site Area Emergency or General Emergency.

2 Revision 0

IOEP-2 EAL Technical Bases Manual 1.3 INITIATING CONDITIONS (ICS)

An IC is a general description of an event or condition that aligns with the definition of one of the four ECLs by virtue of the potential or actual effects or consequences.

Each IC is given a unique identification code consisting of a hyphenated letter combination, a separate letter and one number. The hyphenated letter combination identifies the recognition category, the separate letter identifies the ECL, and the number identifies the sequence of the IC within the recognition category. The EAL identification codes are developed as follows:

Permanently Defueled Recognition Category Applicable to ISFSI

• PD-H - Hazards and Other Conditions Affecting Plant Safety ISFSI Recognition Category

• E-H- Hazards and Other Conditions Affecting ISFSI ISFSI Only ECLs (lowest to highest)

• U - UNUSUAL EVENT

• A-ALERT For an ISFSl-Only station, the UNUSUAL EVENT ICs provide for an increased awareness of abnormal conditions while the ALERT ICs are specific to actual or potential impacts to spent fuel.

Security and Judgment ICs and EALs were included to provide a basis for classifying events that cannot be readily classified based on observable events or physical conditions alone.

1.4 EMERGENCY ACTION LEVELS (EALS)

An EAL is a pre-determined, site-specific, observable threshold for an IC that, when met or exceeded, places the ISFSI in a given ECL.

EAL thresholds may utilize a variety of criteria including instrument readings and status indications; observable events; and entry into particular procedures.

EALs are individually identified by the IC identification code followed by the EAL number, such as E-HU1 .1 for damage to a loaded canister CONFINEMENT BOUNDARY or PD-HA1 .1 for a HOSTILE ACTION within the VEHICLE BARRIER SYSTEM (VBS).

All EAL classification assessments shall be based upon valid indications, reports or conditions. A valid indication, report, or condition, is one that has been verified through appropriate means such that there is no doubt regarding the indicator's operability, the condition's existence, or the report's accuracy.

3 Revision 0

IOEP-2 EAL Technical Bases Manual 1.5 EAL TECHNICAL BASES MANUAL CONTENT EAL Matrix Table This manual contains an EAL Matrix Table that addresses all of the recognition categories for the ISFSI EAL thresholds.

The EAL Matrix Table is designed as an evaluation tool that organizes the ECLs from the highest (ALERT) on the left to the lowest (UNUSUAL EVENT) on the right. Evaluating the EALs for each EGL from highest to lowest reduces the possibility that an event will be under classified. All EALs are to be reviewed for applicability prior to event declaration.

Other user aids, such as wallcharts, may be developed from the EAL Matrix Table to support evaluation of abnormal conditions in other human factored formats.

EAL Documentation Format Each EAL within the technical bases manual is documented in the following manner:

• IC Identification Number

• INITIATING CONDITION

• EAL Threshold Value(s)

• Basis

• Basis Reference(s) 4 Revision O

IOEP-2 EAL Technical Bases Manual 2.0 DEFINITIONS AND ABBREVIATIONS 2.1 DEFINITIONS Advanced Horizontal Storage Module (AHSM) - The Transnuclear AHSM is a reinforced concrete structure for storage of a loaded DRY SHIELDED CANISTER (DSC) at a spent fuel storage facility.

Alert - Events are in progress or have occurred which involve an actual or potential substantial degradation of the level of safety of the ISFSI or a security event that involves probable life threatening risk to site personnel or damage to ISFSI equipment because of HOSTILE ACTION.

Any releases are expected to be limited to small fractions of the EPA Protective Action Guideline exposure levels.

Confinement Boundary - The barrier(s) between spent fuel and the environment once the spent fuel is processed for dry storage. As applied to the SONGS ISFSI, the CONFINEMENT BOUNDARY is defined by the inner surface of the sealed Transnuclear DSC or Holtec MULTl-PURPOSE CANISTER (MPG).

Dry Shielded Canister (DSC) - A Transnuclear welded pressure vessel that provides confinement of intact or damaged fuel assemblies in an inert atmosphere.

Emergency Action Level (EAL) - A pre-determined, site-specific, observable threshold for an INITIATING CONDITION that, when met or exceeded, places the station in a given EGL.

Emergency Classification Level (ECL) - One of a set of names or titles established by the US Nuclear Regulatory Commission (NRG) for grouping off-normal events or conditions according to potential or actual effects or consequences, and the resulting onsite and offsite response actions.

The EMERGENCY CLASSIFICATION LEVELS applicable to the SONGS ISFSI, in ascending order of severity, are:

• UE

• ALERT Hostage - A person(s) held as leverage against the station to ensure demands will be met by the station.

Hostile Action - An act toward the SONGS ISFSI 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. Other acts that satisfy the overall intent may be included.

HOSTILE ACTION should not be construed to include acts of civil disobedience or felonious acts that are not part of a concerted attack on the SONGS ISFSI. Non-terrorism-based EALs should be used to address such activities (i.e., this may include violent acts between individuals within the VBS boundary).

Hostile Force - One or more individuals who are engaged in a determined assault, overtly or by stealth and deception, equipped with suitable weapons capable of killing, maiming, or causing destruction.

Independent Spent Fuel Storage Installation (ISFSI) - A complex that is designed and constructed for the interim storage of spent nuclear fuel and other radioactive materials associated with spent fuel storage.

IOEP-2 EAL Technical Bases Manual Initiating Condition (IC) - An event or condition that aligns with the definition of one of the two applicable ECLs by virtue of the potential or actual effects or consequences.

Multi-Purpose Canister (MPC) - Holtec MPCs are the sealed spent nuclear fuel canisters which provide the CONFINEMENT BOUNDARY for the contained radioactive materials.

Projectile - An object directed toward the SONGS ISFSI that could cause concern for its continued capability, reliability, or personnel safety.

Protected Area - That onsite area within the security boundary as defined in the station's Security Plan.

Security Condition - Any security event as listed in the approved security contingency plan that constitutes a threat/compromise to site security, threat/risk to site personnel, or a potential degradation to the level of safety. A SECURITY CONDITION does not involve a Hostile Action.

Transfer Cask - Containers designed to contain the Transnuclear DSC or Holtec MPC during and after loading of spent fuel assemblies, prior to and during unloading, and to transfer the DSC or MPC to or from the Transnuclear AHSM or Holtec VERTICAL VENTILATED MODULE (WM).

Unusual Event (UE) - Events are in progress or have occurred which indicate a potential degradation of the level of safety of the ISFSI or indicate a security threat to facility protection has been initiated. No releases of radioactive material requiring offsite response or monitoring are expected unless further degradation of occurs.

Vehicle Barrier System (VBS) - Vehicle control measures (passive or active) used to protect against the malevolent use of a land vehicle. The VBS consists of both active and passive components, terrain features, man-made structural features, and vehicle access checkpoints as defined in the SONGS Security Plan.

Vertical Ventilated Module (WM) - The Holtec WM is a subterranean type overpack, which receives and contains the sealed Holtec MPC for interim spent fuel storage at an ISFSI. The Holtec WM supports the MPC in a vertical orientation and provides gamma and neutron shielding, and also provides air flow through cooling passages to promote heat transfer from the MPC to the environs.

IOEP-2 EAL Technical Bases Manual 4.0 EAL TECHNICAL BASES 4.1 PD-HA1 I Initiating Condition:

HOSTILE ACTION within the VBS boundary.

EAL:

PD-HA 1.1. A HOSTILE ACTION is occurring or has occurred within the VBS boundary as reported by the Security Shift Supervisor.

I Basis:

This IC addresses the occurrence of a HOSTILE ACTION within the VBS boundary. This event will require rapid response and assistance due to the possibility of the attack progressing to the ISFSI PROTECTED AREA Security plans and terminology are based on the guidance provided by NEI 03-12, Template for the Security Plan, Training and Qualification Plan, Safeguards Contingency Plan [and Independent Spent Fuel Storage Installation Security Program].

As time and conditions allow, these events require a heightened state of readiness by the staff and implementation of onsite protective measures (e.g., evacuation, dispersal or sheltering). The ALERT declaration will also heighten the awareness of Offsite Response Organizations, allowing them to be better prepared should it be necessary to consider further actions.

This IC does not apply to incidents that are accidental events, acts of civil disobedience, or otherwise are not a HOSTl~E ACTION perpetrated by a HOSTILE FORCE. Examples include the crash of a small aircraft, shots from hunters, physical disputes between employees, etc.

Reporting of these types of events is adequately addressed by the requirements of 10 CFR § 73. 71 or 10 CFR § 50.72.

EAL #1 is applicable for any HOSTILE ACTION occurring, or that has occurred, within the VBS boundary.

This includes any action directed against the ISFSI that is located within the VBS boundary.

In some cases, it may not be readily apparent if an aircraft impact within the VBS boundary was intentional (i.e., a HOSTILE ACTION). It is expected, although not certain, that notification by an appropriate Federal agency to the site would clarify this point. In this case, the appropriate federal agency is intended to be NORAD, FBI, FM or NRC. The emergency declaration, including one based on other ICs/EALs, should not be unduly delayed while awaiting notification by a Federal agency.

IOEP-2 EAL Technical Bases Manual 4.2 PD-HU1 I Initiating Condition:

Confirmed SECURITY CONDITION or threat.

EALs:

PD-HU1 .1. A SECURITY CONDITION that does not involve a HOSTILE ACTION as reported by the Security Shift Supervisor.

PD-HU1 .2. Notification of a credible securit threat directed at the site.

Basis:

This IC addresses events that pose a threat to station personnel or the spent fuel, and thus represent a potential degradation in the level of station safety. Security events which do not meet one of these EALs are adequately addressed by the requirements of 10 CFR § 73. 71 or 10 CFR § 50. 72. Security events assessed as HOSTILE ACTIONS are classifiable under IC PD-HA1.

Timely and accurate communications between SSS and the ISS is essential for proper classification of a security-related event. Classification of these events will initiate appropriate threat-related notifications to station personnel and Offsite Response Organizations. Security plans and terminology are based on the guidance provided by NEI 03-12, Template for the Security Plan, Training and Qualification Plan, Safeguards Contingency Plan [and Independent Spent Fuel Storage Installation Security Program].

EAL #1 references Security Shift Supervisor because these are the individuals trained to confirm that a security event is occurring or has occurred. Training on security event confirmation and classification is controlled due to the nature of Safeguards and 10 CFR § 2.390 information.

EAL #2 addresses the receipt of a credible security threat. The credibility of the threat is assessed in accordance with Security procedures. Credible security threat includes a HOSTILE ACTION within the SITE BOUNDARY outside of the VBS boundary.

Escalation of the ECL would be via IC PD-HA 1.

IOEP-2 EAL Technical Bases Manual 4.5 E-HU1 I Initiating Condition:

Damage to a loaded canister CONFINEMENT BOUNDARY.

EAL:

E-HU1 .1. Damage to a loaded Transnuclear canister CONFINEMENT BOUNDARY as indicated by dose rates greater than EITHER of the following:

• 520 mR/hr (gamma) 3 feet from the surface at the top centerline.

• 190 mR/hr (gamma) 3 feet from the surface of the neutron shield at the midheight centerline.

E-HU1 .2. Damage to a loaded Holtec canister CONFINEMENT BOUNDARY as indicated by dose rates greater than EITHER of the following:

• 60 mR/hr (gamma + neutron) on the top of the closure lid of a WM. A minimum of four (4) dose rate measurements shall be taken on the top of the WM. These measurements shall be taken approximately 90 degrees apart around the circumference of the lid, approximately 18 inches radially inward from the edge of the lid.

• 7000 mR/hr (gamma + neutron) on the side of a TRANSFER CASK. A minimum of four (4) dose rate measurements shall be taken on the side of the TRANSFER CASK, approximately at the cask mid-height plane. The measurement locations shall be approximately 90 degrees apart around the circumference of the cask. Dose rates shall be measured between the radial ribs of the water jacket.

I Basis:

This IC addresses an event that results in damage to the CONFINEMENT BOUNDARY of a storage canister containing spent fuel. It applies to irradiated fuel that is licensed for dry storage beginning at the point that the loaded storage canister is sealed. The issues of concern are the creation of a potential or actual release path to the environment, degradation of one or more fuel assemblies due to environmental factors, and configuration changes which could cause challenges in removing the canister or fuel from storage.

The existence of "damage" is determined by radiological survey. The EAL threshold values, which are a technical specification multiple of "2 times", are used here to distinguish between non-emergency and emergency conditions. The emphasis for this classification is the degradation in the level of safety of the spent fuel canister and not the magnitude of the associated dose or dose rate. It is recognized that in the case of extreme damage to a loaded canister, the fact that the "on-contact" dose rate limit is exceeded may be determined based on measurement of a dose rate at some distance from the canister.

Security-related events for ISFSls are covered under ICs PD-HU1 and PD-HA1.
