SUBJECT:

RE. GINNA NUCLEAR POWER PLANT - RE: EMERGENCY ACTION LEVEL SCHEME UPGRADE (TAC NO. ME7730).

Dear Mr. Pacher:

By application dated December 21,2011, and its supplement dated November 1,2012, Constellation Energy Group, (the licensee), requested prior U.S. Nuclear Regulatory Commission (NRC) approval for proposed changes to the emergency action level (EAL) scheme for the RE Ginna Nuclear Power Plant.

The licensee's requested changes support a conversion from the current EAL scheme to an upgraded scheme based on guidance in Nuclear Energy Institute (NEI) 99-01, Revision 5, "Methodology for Development of Emergency Action Levels," dated February 2008.

The NRC staff has completed its review of the proposed changes to the licensee's EAL scheme and supporting documentation in accordance with Appendix E to Title 10 of the Code of Federal Regulations (10 CFR) Part 50,Section IV.B.(1). We have concluded that the proposed changes meet the standards in 10 CFR 50.47(b) and the requirements of Appendix E to 10 CFR Part 50, and provides reasonable assurance that adequate protective measures can and will be taken in the event of a radiological emergency. Therefore, the licensee's proposed changes to the EAL scheme for the RE. Ginna Nuclear Power Plant, as outlined in the application and its supplement referenced above, are considered acceptable. The basis for our conclusion is contained in the enclosed safety evaluation.

UNITED STATES NUCLEAR REGULATORY COMMISSION WASHINGTON, D.C. 20555-0001 SAFETY EVALUATION BY THE OFFICE OF NUCLEAR REACTOR REGULATION UPGRADE TO EMERGENCY ACTION LEVEL SCHEME CONSTELLATION ENERGY GROUP RE. GINNA NUCLEAR POWER PLANT. LLC RE. GINNA NUCLEAR POWER PLANT DOCKET NOS. 50-244

1.0 INTRODUCTION

By application dated December 21, 2011 (Reference 12), and supplemented by letter dated November 1,2012 (Reference 13), Constellation Energy Group (CENG) (the licensee),

requested prior U.S. Nuclear Regulatory Commission (NRC) approval for proposed changes to the emergency action level (EAL) scheme for the RE. Ginna Nuclear Power Plant (GNPP).

The licensee's requested changes support a conversion from its current EAL scheme to a scheme based on Nuclear Energy Institute (NEI) 99-01, Revision 5, "Methodology for Development of Emergency Action Levels;' dated February 2008 (Reference 5).

GNPPs current EAL scheme is based on generic development guidance from the Nuclear Management and Resources Council/National Environmental Studies Project (NUMARC/NESP)-007, 'Methodology for Development of Emergency Action Levels;' (Reference 3). GNPP requested a revision to its EAL scheme to incorporate the numerous enhancements and clarification efforts made to the generic EAL development guidance resulting in the most recent document, NEI 99-01, Revision 5, which was found to be acceptable for use as generic EAL development guidance by the NRC (Reference 7).

2.0 REGULATORY REQUIREMENTS The NRC staff reviewed the proposed revision against the regulations and guidance described below.

-2 2.1 Regulations 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) states, in part, that

[...] 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 the onsite and offsite emergency response plans must meet for NRC staff to make a positive finding that there is reasonable assurance that adequate protective measures can and will be taken in the event of a radiological emergency.

Planning Standard (4) of this section requires that onsite and offsite emergency response plans contain:

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.

Section 50.47(b)(4) to 10 CFR specifies a standard emergency classification and action level scheme, assuring that implementation methods are relatively consistent throughout the industry for a given reactor and containment design while simultaneously providing an opportunity for a licensee to modify its EAL scheme as necessary to address plant-specific design considerations or preferences.

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

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 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 on site and offsite monitoring. Sy June 20,2012, for nuclear power reactor licensees, these action levels must include hostile action that may adversely affect the nuclear power plant ...

GNPP's proposed changes were submitted to the NRC for a technical and regulatory review prior to implementation by the licensee. This review is based upon a revision to the GNPP EAL scheme provided in the licensee's application letters and supplemented by the licensee's responses to the NRC staff's requests for additional information. Attachment 3 of the licensee's letter dated November 1, 2012 (Reference 13) contains the final version of the licensee's proposed plant-specific EAL scheme for GNPP and is therefore, the final version reviewed by the NRC staff for acceptability.

2.2 Guidance EAL development guidance was initially established via Generic Letter (GL) 79-50 (Reference 1) and was subsequently established in NUREG-0654/FEMA-REP-1 (Reference 2),

which was endorsed as an approach for the development of an EAL scheme via NRC Regulatory Guide (RG) 1.101, Revision 2 (Reference 6). As industry and regulatory experience was gained with the implementation and use of EAL schemes, the industry issued revised EAL scheme development guidance documents to reflect lessons learned. To date, NUMARC/NESP-007 (Reference 3), NEI 99-01 Revision 4 (Reference 4), and NEI 99-01 Revision 5 were provided to the NRC for review and endorsement as generic (non plant specific) EAL development guidance. RG 1.101, Revisions 3 and 4 (Reference 6) endorsed NUMARC/NESP-007 and NEI 99-01 Revision 4 as acceptable alternatives for licensees to consider in the development of their plant-specific EAL schemes, as well as allowing licensees to develop plant-specific EALs based upon an alternative approach not endorsed by the NRC.

NEI 99-01 Revision 5 was endorsed by the NRC as generic (non plant-specific) EAL development guidance via letter dated February 22,2008 (Reference 7), and this endorsement is expected to be reflected in the next revision of RG 1.101.

The EAL development guidance contained in GL 79-50, NUREG-0654/FEMA-REP-1, NUMARC/NESP-007, NEI 99-01 Revision 4, and NEI 99-01 Revision 5 are all considered generic EAL development guidance, as they are not plant-specific and may not be entirely applicable for some reactor designs. However, the guidance contained in these documents bounds the most typical accident/event scenarios for which emergency response is necessary, in a format that allows for industry standardization and consistent regulatory oversight. Most licensees choose to develop their plant-specific EAL schemes using the latest endorsed EAL development guidance with appropriate plant-specific alterations as applicable. Pursuant to 10 CFR Part 50, Appendix E, Section IV.S (2), a revision to an EAL must be approved by the NRC before implementation, if the licensee is changing from one EAL scheme to another EAL scheme.

In sum, the NRC staff considers the following methods acceptable for use in developing plant specific EALs that meet the requirements of Section IV of Appendix E to 10 CFR Part 50 and 10 CFR 50.47(b)(4), with the understanding that licensees may want to develop EALs that differ from the applicable guidance document as allowed in RG 1.101 and in the letter dated February 22, 2008:

  • Appendix 1, "Emergency Action Level Guidelines for Nuclear Power Plants," to NUREG-0654/FEMA-REP-1, "Criteria for Preparation and Evaluation of Radiological Emergency Response Plans and Preparedness in Support of Nuclear Power Plants,"

dated November 1980;

- 4

  • NUMARC/NESP-007, Revision 2, "Methodology for Development of Emergency Action Levels," dated January 1992;
  • NEI 99-01, Revision 4, "Methodology for Development of Emergency Action Levels,"

dated January 2003; and

  • NEI 99-01, Revision 5, "Methodology for Development of Emergency Action Levels,"

dated February 2008.

NRC Regulatory Issue Summary (RIS) 2003-18, with Supplements 1 and 2, "Use of NEI 99-01, Methodology for Development of Emergency Action Levels" (Reference 9), also provide guidance for developing or changing a standard emergency classification and action level scheme. In addition, this RIS and its supplements provide recommendations to assist licensees, consistent with Section IV.B of Appendix E to Part 50, in determining whether to seek prior NRC approval of deviations from the guidance.

Regardless of the generic EAL scheme development guidance document used by a licensee to develop its EAL scheme, or if a licensee chose to develop its EAL scheme using an alternative approach not endorsed by the NRC, or a combination of the two (most typical), the NRC staff will review the EAL scheme to assure it meets the requirements of Section IV of Appendix E to 10 CFR Part 50 and 10 CFR 50.47(b)(4).

3.0 TECHNICAL EVALUATION

In its application and supplemental letter, the licensee submitted the proposed EAL scheme, the technical basis, a comparison matrix, the EAL numbering scheme, and an explanation for any difference or deviation from NEI 99-01, Revision 5. The comparison matrix provided a cross reference relating the proposed EAL scheme to the EAL scheme in NEI 99-01, Revision 5 and the current EAL scheme.

The licensee currently utilizes an EAL scheme based on the generic EAL scheme development guidance from NUMARC/NESP-007, Revision 2 (Reference 3) with plant-specific modifications due to design issues and/or licensee preference. The licensee is converting to an EAL scheme using the development guidance from NEI 99-01, Revision 5 (Reference 5), with plant-specific modifications due to design issues and/or licensee preference.

The proposed plant-specific EAL scheme is unique to the licensee; however, to ensure consistency and regulatory stability, the NRC staff reviewed the proposed plant-specific EAL scheme to ensure the following key characteristics of an effective EAL scheme are in place:

  • Consistency (Le., the EALs would lead to similar decisions under similar circumstances at different plants), up to and including standardization in intent, if not in actual wording;
  • Human factors engineering and user friendliness;

- 5

  • Potential for classification upgrade only when there is an increasing threat to public health and safety;
  • Ease of upgrading and downgrading;
  • Thoroughness in addressing and disposing of the issues of completeness and accuracy raised regarding Appendix 1 to NUREG-0654;
  • Technical completeness for each classification level;
  • Logical progression in classification for multiple events; and
  • Objective and observable values.

To aid in understanding the nomenclature used in this safety evaluation, for each category of EALs reviewed the following naming/numbering convention is used: the first letter signifies the

=

category; the second letter signifies the classification level (G General Emergency (GE),

S =Site Area Emergency (SAE), A =Alert, U = Notification of Unusual Event (UE>>; and the number is the applicable number from the plant-specific EAL scheme. For ease of use, this safety evaluation will use the numbering system from the plant-specific EAL scheme rather than from the generic EAL development guidance.

3.1 Category 'R' - Abnormal Radiological Release/Radiological Effluent 3.1.1 EALSet RG1/RS1/RA1/RU1 This EAL set is based upon plant-specific indications of a release of radioactivity (gaseous and/or liquid).

3.1.3 EAL RA3 This EAL is based upon indications of a rise in plant radiation levels that impedes normal access to the Control Room (CR) and Central Alarm Station (CAS). The Alert EAL is primarily intended to ensure the plant emergency response organization is activated to support the CR in removing the impediment to normal access to the CR and CAS. Indications of increasing radiation levels in the plant are bounded by indication of fission barrier loss or potential loss, as well as in RS1 and RG1.

The licensee chose to modify this EAL set by using a site-specific implementation method that uses a modified numbering format and EAL sequence other than that provided in the generic EAL scheme development guidance, as well as using 'R' in lieu of 'A' to reference this category.

3.4 Category 'F' - Fission Product Barrier Matrix This category is unique in the overall EAL scheme, as the thresholds are not intended to be stand-alone indicators of a particular event occurring at the plant. Rather, they are to be used as triggers within the particular logic configuration needed to reflect a loss or potential loss of a fission product barrier. U.S. nuclear power plants have three fission product barriers: fuel cladding, the RCS, and the primary containment. Licensees are to develop thresholds that provide EAL decision-makers input into making an event declaration based upon degradation of one or more of these fission product barriers.

There are numerous triggers used as logic inputs to decide on the appropriate classification based upon the number of loss and/or potential loss indicators that are triggered for each barrier. By design, these indicators are redundant with other Similar indicators in the Category

'R' and Category'S' EAL sets, due to the importance for licensees to be able to recognize reactor and/or fission product barrier events as timely as possible using the best available indicators from several different perspectives.

The NRC staff verified that the logic used to determine the appropriate emergency claSSification is consistent with the generic EAL scheme development guidance.

The instrumentation and set points derived for this EAL category are consistent with the overall EAL scheme development guidance, address the plant-specific implementation strategies provided, and are consistent with a standard EAL scheme, as required by 10 CFR S0.47(b)(4).

3.S Category 'H' - Hazards 3.S.1 EAL Set HG4/HS4/HA4/HU4 This EAL set is based upon security-related events originally developed in accordance with the guidance from NRC Bulletin 200S-02 (Reference 10) or RIS 2006-12 (Reference 11) for licensees to implement regardless of the specific version of the generic EAL scheme development guidance used, or if the particular licensee developed its EAL scheme using an

- 11 alternative approach. Based upon lessons learned from the implementation and use of this EAL set, particularly the insights gained from combined security and emergency preparedness drills, the NRC staff and the industry worked to enhance the language of these EALs so as to eliminate any confusion without changing the intent of the EAL set as set forth in NRC Bulletin 2005-02 and RIS 2006-12. The NRC staff generated EAL Frequently Asked Question (EALFAQ) 2009-48 (Reference 8) to address the changes made to the generic EAL scheme development guidance document.

Therefore, these EALs are acceptable for implementation Internal flooding events are appropriately developed using the generic EAL development guidance with plant-specific terminology and plant-specific areas of consideration determined for these EALs. While consistent with the development strategies stated in the generic EAL development guidance, the actual wording used is different. However, these EALs are consistent with a standard EAL scheme and meet the requirements of Section IV of Appendix E to 10 CFR Part 50 and 10 CFR 50.47(b)(4). Therefore, these EALs are acceptable for implementation.

Events based upon vehicle crashes within the protected area or vital area have typically been difficult to differentiate for EAL purposes, between the UE and Alert classification levels. GL 79 50, NUREG-0654/FEMA-REP-1, and NUMARC/NESP-007 used language equating vehicles to aircraft, trains, and barges. NEI 99-01 Revision 4 addresses vehicles that are large enough to cause damage. With the issuance of NRC Bulletin 2005-02 (Reference 10), the need for EALs related to airborne, waterborne, or land-based security events has been resolved with the development of security-specific EALs. In addition, the intended basis for a UE EAL conSiders, among other factors, the resultant degradation in the level of safety of the plant. Eliminating the UE EAL for vehicle crashes is consistent with the intent of the UE classification and removes

- 13 any misunderstanding regarding the remaining Alert classification. The Alert classification is based upon indications of degraded performance or visible damage to a specific list of areas considered applicable to this EAL. Removing the UE EAL based upon vehicle crashes, and revising the wording of the remaining Alert EAL, is consistent with a standard EAL scheme and meets the requirements of Section IV of Appendix E to 10 CFR Part 50 and 10 CFR 50.47(b)(4).

Therefore, the revisions to these EALs are acceptable for implementation.

3.7 Summary The NRC staff has reviewed the technical bases for the proposed EAL scheme, the modifications from NEI 99-01 Revision 5, and the licensee's evaluation of the proposed changes. The licensee chose to modify its EAL scheme from the generic EAL scheme development guidance provided in NEI 99-01 Revision 5 in order to adopt a format that is better aligned with how it currently implements its EALs, as well as with plant-specific writer's guides and preferences. The NRC staff determined that these modifications do not alter the intent of any specific EAL within an EAL set, EAL category, or within the entire EAL scheme as stated in NEI 99-01 Revision 5.

Based on its review, the NRC staff has determined that the proposed EAL scheme uses objective and observable values, is worded in a manner that addresses human factors engineering and user friendliness concerns, follows logical progressions for escalating events, and allows for event downgrading and upgrading based upon the potential risk to the public health and safety. Risk assessments were appropriately used to set the boundaries of the emergency classification levels and ensure that all EALs that trigger an emergency classification are in the same range of relative risk. In addition, the NRC staff found that the proposed EAL scheme was technically complete and consistent with EAL schemes implemented at similarly designed plants.

4.0 CONCLUSION

Based on the above, the NRC staff has determined that the proposed changes meet the requirements in Appendix E to 10 CFR Part 50 and the planning standards of10 CFR 50.47(b).

Therefore, the NRC staff concludes that the proposed EAL scheme, as stated in Attachment 3 of the licensee's letter dated November 1,2012 (Reference 13), provides reasonable assurance that the licensee can and will take adequate protective measures in the event of a radiological emergency.

Dear Mr. Pacher:

By application dated December 21, 2011, and its supplement dated November 21, 2012, Constellation Energy Group, (the licensee), requested prior U.S. Nuclear Regulatory Commission (NRC) approval for proposed changes to the emergency action level (EAL) scheme for the RE Ginna Nuclear Power Plant.

The licensee's requested changes support a conversion from the current EAL scheme to an upgraded scheme based on guidance in Nuclear Energy Institute (NEI) 99-01, Revision 5, "Methodology for Development of Emergency Action Levels," dated February 2008.

The NRC staff has completed its review of the proposed changes to the licensee's EAL scheme and supporting documentation in accordance with Appendix E to Title 10 of the Code of Federal Regulations (10 CFR) Part 50,Section IV.B.(1). We have concluded that the proposed changes meet the standards in 10 CFR 50.47(b) and the requirements of Appendix E to 10 CFR Part 50, and provides reasonable assurance that adequate protective measures can and will be taken in the event of a radiological emergency. Therefore, the licensee's proposed changes to the EAL scheme for the RE. Ginna Nuclear Power Plant, as outlined in the application and its supplement referenced above, are considered acceptable. The basis for our conclusion is contained in the enclosed safety evaluation.
