3 1 June 8, 17 NEI 17-03, [Rev A]    1    INTRODUCTION The NRC pursued numerous regulatory actions following the 2011 Fukushima Dai-ichi event in Japan. These actions began with the work of the Near-Term Task Force (NTTF) and the development of the associated NTTF recommendations.
The NRC's response to the NTTF Report was provided in SECY- 11-0124, ("Recommended Actions to Be Taken without Delay from the Near-Term Task Force Report"), and SECY-11-0137 ("Prioritization of Recommended Actions To Be Taken in Response to Fukushima Lessons Learned").
These two papers identified actions to be taken in the near term and prioritized the NTTF recommendations.
The near-term actions ultimately culminated in the issuance of three orders, a request for information under 10 CFR Section 50.54(f) that addressed several regulatory issues, and two Advance Notices of Proposed Rulemaking (ANPR). The regulatory efforts to address lessons learned from Fukushima have evolved over time, and the two rulemaking activities discussed in the ANPRs were consolidated into the Mitigation of Beyond-Design-Basis Events (MBDBE)  rule: 10 CFR 50.155. 10  CFR  50.155  applies  to  power  reactor  applicants and  licensees  and  includes  the  following:
Provisions that make generically applicable requirements previously imposed by Order EA-12-049, "Order Modifying Licenses with Regard to Requirements for Mitigation Strategies for Beyond-Design-Basis External Events," dated March 12, 2012 (ADAMS ML12054A735), for the mitigation of beyond-design-basis external events. These requirements constitute the majority of the requirements in this rule, and are located mainly in 10 CFR 50.155(b)(1), with portions in paragraphs (c), (d), (e), and (g) as described further below. Requirements for licensees to consider the effects of the reevaluated seismic and flooding hazards information within the mitigation strategies and guidelines, in accordance with the Commission direction provided in SRM-COMSECY-14-0037 (ADAMS ML15089A236), "Staff Requirements
- COMSECY-14-0037 -Integration of Mitigating Strategies for Beyond-Design-Basis External Events and the Reevaluation of Flooding Hazards," dated March 30, 2015. These requirements appear in 10 CFR 50.155(b)(2).
Requirements previously in 10 CFR 50.54(hh)(2) for mitigation of the effects of a loss of a large area of the plant due to explosions or fire. These requirements appear in 10 CFR 50.155(b)(3).
Requirements to integrate the above capabilities with the emergency operating procedures.
These requirements appear in 10 CFR 50.155(b)(4).
Reasonable protection requirements that enable the proper degree of regulatory assurance to be applied to the equipment and structures, systems, and components (SSCs) that perform a beyond- design-basis function for the purposes of 10 CFR 50.155. These requirements appear in 10 CFR 50.155(c)(2) and (c)(3). Supporting requirements for the integrated response capability that include staffing, communications, training, drills or exercises, and documentation of changes. These requirements are found in 10 CFR 50.155(b), (c), (d), (e) and (g). Provisions that make generically applicable requirements previously imposed by Order EA-12-051, "Order Modifying Licenses with Regard to Reliable Spent Fuel Pool Instrumentation,"
(ADAMS ML12056A044), for remotely monitoring the spent fuel pool wide-range level. These requirements appear in 10 CFR 50.155(f).
Requirements that facilitate the decommissioning of reactors that are subject to this rule. These requirements appear in 10 CFR 50.155(a)(2).
 
2 June 8, 17 NEI 17-03, [Rev A]      Provisions that rescind orders, including Orders EA-12-049 and EA-12-051, for which 10 CFR 50.155 will now provide the governing substantive requirements.
These requirements appear in 10 CFR 50.155(i).
Provisions that facilitate the removal of a variety of license conditions for which 10 CFR 50.155 will now provide the governing substantive requirements.
These requirements appear in 10 CFR 50.155(i).
This document provides guidance to assist licensee implementation of 10 CFR 50.155 provisions.
Note that NEI has prepared another document that can assist rule implementation.
The "BD B Event Response Program Manual" provides an outline (or "roadmap") for developing an emergency response program manual that can be used at the fleet or site level. Rather than building a new program manual, this document recommends that the various elements it describes be blended into the existing FLEX/SFPI program document. The "BDP Event Response Program Manual" can be found at https://www.nei.org/Member

-Response-for-Members. 2 UFSAR CONSIDERATIONS There is no specific requirement to address beyond-design-basis aspects of 50.155 compliance topics in the UFSAR. Note that some aspects of the changes made to address beyond
-design-basis accidents should be included in the UFSAR if they affect design basis systems, structures, or components already included in the document (e.g., installation of new connection points on safety related equipment or systems for FLEX pumps and generators, changes to the seismic capacity of tanks, etc.). 3 SCOPE  NEI 17-03 provides guidance for the implementation of 10 CFR 50.155 through matrices that cross reference the rule and its statements of consideration (FRN MLXXXXXX proposed rule ML16292A026
) with existing NEI guidelines and other applicable references.
Some of the matrices provide assessments of potential gaps that a licensee may encounter during implementation of 10 CFR 50.155. The top-level matrix in NEI 17-03 is the "Rule Requirements Cross Reference." This matrix does not address a specific document; rather it relates all of the rule paragraphs to the various documents and guidelines that provide more information on the applicable requirement.
The other matrices in NEI 17-03 address specific documents as follows:  NEI 12-06, Revisions 0, 2, and 4: Diverse and Flexible Coping Strategies (FLEX) Implementation Guide NEI 12-01, Revision 0: Guidance for Assessing Beyond Design Basis Accident Response Staffing and Communication Capabilities NEI 13-06, Revision 1: Elements to Emergency Response Capabilities for Beyond Design Basis Events and Severe Accidents  NEI 14-01, Revision 1: Emergency Response Procedures and Guidelines for Beyond Design Basis Events and Severe Accidents  RG 1.226 to JLD-ISG-2012-01: Flexible Mitigation Strategies for Beyond Design Basis Events  RG 1.227 to JLD-ISG-2012-03: Wide Range Spent Fuel Pool Level Instrumentation A matrix was not developed for RG 1.228, Integrated Response Capabilities for Beyond-Design-Basis Events , because this regulatory guide did not evolve from a single ISG, rather it was created to document the NRC's endorsements of the emergency response guidelines that were developed subsequent to the Fukushima event (NEI 12-01, 13-06, and 14-01).
3 June 8, 17 NEI 17-03, [Rev A]    NEI  17-03  matrices  fall  into  two  types:  cross  reference,  and    comparison.
A brief description of each matrix is provided below:
Cross Reference Matrix o MBDBE Rule Requirements Cross Reference Matrix - This matrix relates every paragraph in the final rule to associated industry guidance and relevant information in the rule's "Statements of Consideration
." Differences and applicable generic actions are identified.
Revision Comparison Matrices o NEI 12-06 Revision Comparison Matrix - NEI 12-06 ("Diverse and Flexible Coping Strategies (FLEX) Implementation Guide") was the industry's principal guidance for the design and implementation of FLEX. Licensees may presently be implementing different revisions of this document. This matrix identifies the differences between the three revisions of NEI 12- 06 that have been endorsed by the NRC (revisions 0, 2, and 4) and assists with the decision of whether to adopt a different revision and what should be addressed if an older revision is used. o RG 1.226 to JLD-ISG-1201-01 Comparison Matrix - JLD-ISG-2012-01 ("Compliance with Order EA-12-049, Order Modifying Licenses with Regard to Requirements for Mitigation Strategies for Beyond-Design-Basis External Events") endorsed revisions 0 and 2 of NEI 12-06. RG 1.226, ("Flexible Mitigation Strategies for Beyond-Design-Basis Events") endorses revision 4 of NEI 12-06. This matrix examines the differences between the ISG and the RG. o RG  1.227  to  JLD-ISG-2012-03  to  RG  1.227  Comparison Matrix  -  JLD-ISG-2012-03 ("Compliance with Order EA-12-051, Reliable Spent Fuel Pool Instrumentation")
endorsed revision 1 of NEI 12-02 ("Industry Guidance for Compliance with NRC Order EA-12-051, 'To Modify Licenses with Regard to Reliable Spent Fuel Pool Instrumentation'".
RG 1.227, "Wide-Range Spent Fuel Pool Level Instrumentation")
also endorses revision 1. This matrix examines the differences between the ISG and the RG. o NEI 12-01 Comparison Matrix - NEI 12-01 ("Guideline for Assessing Beyond Design Basis Accident Response Staffing and Communications Capabilities")
was developed and endorsed by the NRC years before 10 CFR 50.155 became effective.
This guideline is referenced by the Regulatory Guide that covers Integrated Response Capabilities (RG 1.228), but like NEI 13-06 and 14-01, not all of the guideline is applicable to implementation of 10 CFR 50.155. This matrix identifies the sections of NEI 12-01 that are applicable and provide interpretations and other information relevant to each applicable section. o NEI 13-06 Comparison Matrix - NEI 13-06 ("Enhancements to Emergency Response Capabilities for Beyond Design Basis Events and Severe Accidents")
was endorsed by the NRC and referenced by RG 1.228, but like NEI 12-01 and 14-01, not all of the guideline is applicable to implementation of 10 CFR 50.155. This matrix identifies the sections of NEI 13- 06 that are applicable and provides interpretations and other information relevant to each applicable section. Note a portion of NEI 13
-06 was committed to by licensees because of a voluntary commitment to the NRC in fall 2015.
o NEI 14-01 Comparison Matrix - NEI 14-01 ("Emergency Response Procedures and Guidelines for Beyond Design Basis Events and  Severe Accidents")
was endorsed by the NRC and referenced by RG 1.228, but like NEI 12-01 and 13-06, not all of the guideline is applicable to implementation of 10 CFR 50.155. This matrix identifies the sections of NEI 14-01 that are applicable and provides interpretations and other information relevant to each applicable section. This matrix also identifies that generic activities are planned to support licensee implementation of 10 CFR 50.155. Note a significant portion of NEI 14
-01 was committed to by licensees because of a voluntary commitment to the NRC in fall 2015.
4 June 8, 17 NEI 17-03, [Rev A]    Each matrix includes a summary that highlights the key conclusions of its gap assessment.
Many of these matrices identify various generic industry activities that are in place or planned to assist with implementation of 10 CFR 50.155. 4 GENERAL MATRIX USAGE  Users performing gap assessments for implementation of 10 CFR 50.155 should consider the following guidance:
Information in the document "Section" column of some matrices may only be a summary of the guidance from the indicated section. Users are encouraged to refer to the specific section of the document for which the gap assessment has been performed to obtain a full understanding of the guidance. The Statement of Consideration s provide s important information concerning the Nuclear Regulatory Commission's intent with respect to the rule requirements.
Applicable sections of the Statement of Consideration s are referenced in the matrices. Users are encouraged to read the referenced sections of the Statement of Consideration s to gain insights into the requirements and how the interpretations in the matrices were derived. Users do not have to revalidate generic information in the table. The information has been developed and reviewed by members of the NEI MBDBE Rule Implementation Sub Group for use as a starting point to assist users in successful rule implementation.
Users should validate information in the Gap Assessment
/ Recommended Action column for  site specific applicability, even where "none" appears in that column (i.e., verify that there are no site specific gaps for that portion of the guidance).
NOTE THAT IN ALL CASES, IT IS THE RESPONSIBILITY OF EVERY LICENSEE TO EXAMINE ITS LICENSING BASES AND DETERMINE WHAT ADDITIONAL ACTIONS MAY BE NECESSARY TO ACHIEVE FULL COMPLIANCE WITH 10 CFR 50.155  5 PREVIEW OF SIGNIFICANT GAPS AND ACTIONS Each matrix includes an introduction that summarizes its major impacts and necessary actions. This section presents a preview of the more significant of these items. 5.1 10 CFR 50.155 Rule Cross Reference Matrix  Licensees who have not implemented NEI 12-06, revision 4 will need to update their programs to address this revision, or be able to explain why implementation of an earlier revision is acceptable.
See the NEI 12-06 Revision Comparison Matrix for an identification of the differences.
10 CFR 50.155(g) applies change control requirements to the entire rule, including EDMGs (see 155(b)(3)).
Ensure that a specific change control process is in place for EDMGs to document that changes to them continue to meet the requirements
. Furthermore, ensure configuration control procedures properly handle the hand-off between different change control requirements.
10 CFR 50.155 must be implemented within 2 years of its effective date for most plants, or 3 years for BWRs that received the EA-13-109 Order on severe accident capable hardened containment vents, unless delays associated with reevaluated hazards apply. In that case related to hazards
, a request (not an exception) for an alternative compliance date must be submitted within 90 days of the rule effective date. Ensure that the site-specific voluntary commitment to perform multiple source term dose assessments is maintained.
Ensure that the NSIAC Initiative (voluntary commitment) on SAMGs is maintained.
 
5 June 8, 17 NEI 17-03, [Rev A]    5.2 NEI 12-06 Revision Comparison Matrix Validation Requirements including providing a basis for time sensitive actions performed more than 24 hours after the initiation of the event. (Section 3.2.1.7 and Appendix E)  Incorporation by reference of several supplemental guidance documents.
(Section 3.2.1.13)
Clarification on  minimum  quantities of  hoses  and  cables  to  be  maintained allowing  for  potential reduction in equipment.
(Section 3.2.2)
Clarifications on minimum Spent Fuel Pool Cooling Strategy spray requirements allowing for potential reduction in equipment.
(Table 3-1, 3-2 and Appendix C, D)  Clarifications on alternate locations for instrument readings. (Section 5.3.3)
Clarifications to support using existing station processes to manage maintenance and testing.  (Section 11.5.2)  Clarifications to support managing out of service time include separating functional from protected and using station corrective actions and work control processes.
(Section 11.5.3)  Clarification on Configuration Control to support long term sustainability of FLEX Program including FLEX Strategy change management.
(Section 11.8)
Removal of recommendation to maintain Final Integrated Plan (FIP) as a living document. (Section 13.2) 5.3 NEI 12-01 Comparison Matrix  NOTES: o 10 CFR 50.155(b)(5) requirements  for staffing capabilities are applicable to the requirements of 10 CFR 50.155 (b)(1) through (b)(3).
o 10 CFR 50.155(c)(4) requirements for  communications capabilities  are  applicable  to  the requirements of 10 CFR 50.155 (b)(1) and (b)(2).. o Although the requirements for communications capabilities contained in 10 CFR 50.155(c)(4) are not applicable to paragraph 10 CFR 50.155(b)(3) (EDMGs), all licensees have existing communications capabilities supporting EDMGs at the guidance level. See the B.5.b Phase 1 guidance letter dated February 25, 2005, Items B.1.i and B.2.b. Further details are available in NUREG 0800, Standard Review Plan, Section 19.4, Acceptance Criteria Item 12.
Verify drill or exercise critiques and training feedback mechanisms include consideration of staffing and communications capabilities and assessments in the performance of 10 CFR 50.155 related drills, exercises and training. Verify the applicable change control process (e.g., 10 CFR 50.155(g) as implemented in the FLEX program document) contains adequate administrative controls for the identification of impacts to staffing and communications assessments that may impact the implementation of 10 CFR 50.155(b) strategies.
Include a demonstration of the associated communications capability when conducting the initial drill or exercise that demonstrates the capability to transition to and use one or more of the strategies and guidelines in either paragraphs (b)(1), (b)(2) or (b)(3) of 10 CFR 50.155. This drill or exercise must be completed within four years of the effective date of the rule.
Confirm communications capabilities committed to in response to the 10 CFR 50.54(f) letter comply with the requirements of 10 CFR 50.155(c)(4).Verify that communications equipment necessary to implement 10 CFR 50.155(c)(4) or to implement 10 CFR 50.155(b)(3) strategies is included in inventory checklists and is periodically verified functional with periodic maintenance tasks and frequencies defined. Verify that communications equipment contracts with vendors supporting communications equipment necessary to implement 10 CFR 50.155(c)(4) are maintained current and periodically verified. Verify that communications equipment procurement specifications or purchasing documents are consistent with requirements normally applied to other EP equipment and should be commonly available, commercial grade with readily available parts and replacement.
 
6 June 8, 17 NEI 17-03, [Rev A]    Verify that agreements with communications service providers that enable access to Government Emergency Telecommunications Service (GETS), the Telecommunications Service Prior ity (TSP) programs and the Wireless Priority Service (WPS) are maintained current and periodically verified. Information related to these services may be obtained from https://www.dhs.gov/office
-emergency-communications, under the Response Support section of the web page. Note that the National Communications Service (NCS) referenced in NEI 12
-01 was disbanded by Executive Order 13618 on July 6, 2012 and the cited website is no longer functional
. Verify agreements with communications providers of Emergency Services (e.g., satellite phone service) are maintained current and periodically verified.
 
7 June 8, 17 NEI 17-03, [Rev A]    5.4 NEI 13-06 Comparison Matrix  A site must have the capability to predict offsite doses  during an event involving an extended loss of all AC power affecting all onsite units. Previously, the requirement to perform this did not require the assumption of an extended loss of AC power. Even though not required by the rule, licensee regulatory commitments include the capability to predict dose from multiple source terms.
A n ERO role identified as "Ultimate Decision Maker" is defined. This individual is assigned authority and responsibility for providing overall direction on the implementation of EOPs, FSGs, EDMGs and SAMGs for a unit or set of units. On an eight (8) year frequency, sites must conduct drills demonstrating BDB strategies (including communications capabilities)
, including:
o A drill that demonstrates the integrated use of FLEX strategies under the control of an Abnormal Operating Procedure (AOP) or Emergency Operating Procedure (EOP), as appropriate to the postulated scenario. o A drill that demonstrates the transition from a controlling AOP, EOP or Extensive Damage Mitigation Guidelines (EDMG) into Severe Accident Management Guidelines (SAMGs), and the selection of appropriate severe accident management strategies.
Even though not required by the rule, licensee regulatory commitments include SAMGs to be integrated with the EOP network. o A drill that demonstrates the use of EDMG strategies.
o A drill or drills to demonstrate the capability to utilize equipment necessary to implement each strategy for responding to a beyond design basis event or severe accident. It is important to note that while it is acceptable to use an EP exercise to accomplish the new drill requirements, it is recommended that exercises not be used to meet these requirements.
Graded exercises serve a specific purpose to meet the regulatory required emergency planning requirements.
Combining BDB drills with a graded exercise could lead to confusion and conflicts that interfere with objectives of either or both of the activities.
5.5 NEI 14-01 Comparison Matrix  Verify Severe Accident Management Guidelines (SAMGs) are revised and maintained in accordance wi t h the new NSSS Owners Group guidance by the utility commitment date in the letter sent to the NRC. Integrate the appropriate guidelines (FSGs, EDMGs) with the EOPs in accordance with the revised NSSS Owner's Group guidance.
Provide the necessary training of new tasks on the procedure integration using the SAT process
. Designate a member of the Emergency Response Organization (ERO) as the Ultimate Decision Maker (UDM). Provide the necessary training required for the position to ERO personnel designated
. 5.6 RG 1.226 to JLD-ISG-1201-01 Comparison Matrix  RG 1.226 endorses NEI 12-06, Revision 4, but its implementation section allows use of other NRC acceptable methods. The ISG recognizes that FLEX equipment may be pre-staged for up to 45 days to reduce the risk of maintenance or outage activities.
All other instances of unavailability due to the lack of reasonable protection are limited to 14 days. The RG 1.226 discussion on this topic only includes the 14 day allowed outage time with no mention of the exception for 45 days if deployed to reduce the risk of maintenance or outage activities.
However, in the NRC Staff's concluding position, the NRC Staff states that Section 11.5.4 provides an acceptable method for controlling unavailability of the equipment to satisfy that element of reasonable protection.
Note there is a distinction for deployed equipment for maintenance or outage activities with regard to reasonable protection.
 
8 June 8, 17 NEI 17-03, [Rev A]  5.7 RG 1.227 to JLD-ISG-2012-03 Comparison Matrix  The Applicable Regulations section of RG 1.227 explains a 10 CFR 50.155(f) requirement that each licensee provide reliable means to remotely monitor wide-range water level for each spent fuel pool at its site until five years have elapsed since all of the fuel within that spent fuel pool was last used in a reactor vessel for power generation
. Paragraph 50.155(f) removes the requirement for operating nuclear power plants to provide wide
-range spent fuel pool level monitoring capabilities for spent fuel pools that contain only fuel greater than five years old.
This condition typically exists at plants with multiple spent fuel pools that use only one of the pools for freshly discharged fuel.
Paragraph 50.155(a)(2)(i) removes the requirement for wide
-range spent fuel pool level monitoring capabilities for all spent fuel pools at a nuclear power plant that has permanently ceased operation and removed all fuel from the reactor vessel once the NRC has docketed the appropriate certifications without regard to the age of the fuel in the pools.
6 MBDBE RULE CROSS REFERENCE  Introduction The Mitigation of Beyond Design Basis Events (MBDBE) Rule Cross Reference matrix identifies sources of additional guidance and background for every paragraph in 10 CFR 50.155. It also includes information on the following related regulations and two subjects that were not included in the rule. 10  CFR  50  Appendix  E  -  "Emergency Planning  and  Preparedness for  Production and  Utilization Facilities" 10 CFR 52.80 - "Contents of applications:
additional technical information" Multiple Source Term Dose Assessments (MSTDAs)  Severe Accident Mitigation Guidelines (SAMGs)  10 CFR 50.155 does not include requirements for MSTDAs and SAMGs, except for a requirement to integrate the SAMGs with the existing EOPs, because the NRC took credit for pre-existing licensee commitments (NSIAC Initiative) in these areas. It is important that licensees maintain these commitments in order to remain consistent with the basis for the rule. The Commission directed the staff in SRM
-SECY-15-0065 to incorporate oversight of SAMGs into the ROP.
Major Gap Assessments and Recommended Actions The information provided below is a summary of the most significant observations in the 10 CFR 50.155 Rule Requirements Cross Reference Matrix. Licensees who have not implemented NEI 12-06, rev 4 should either update their programs to address this revision, or be able to explain why implementation of an earlier revision is acceptable.
See the NEI 12-06 Revision Comparison Matrix for an identification of the differences.
The impact of many of the rule requirements depends on associated guidance. When this is the case, the 10 CFR 50.155 Rule Requirements Cross Reference Matrix refers the user to the appropriate guideline matrix in this document for information on impact and actions.
10 CFR 50.155(g) applies change control requirements to the entire rule, including EDMGs (that are required under paragraph 155(b)(3)).
Ensure that a specific change control process is in place for EDMGs to document that changes to them continue to meet the requirements
. Furthermore, ensure configuration control procedures properly handle the hand-off between the different change control requirements that govern other plant equipment and programs. 10 CFR 50.155 must be implemented within 2 years of its effective date for most plants, or 3 years for BWRs that received the EA-13-109 Order on severe accident capable hardened  containment vents unless delays associated with reevaluated hazards apply. In that case related to hazards
, a request (not an exception) for an alternative compliance date must be submitted within 90 days of the rule effective date. Ensure that the site-specific commitment for a capability to perform MSTDA s is maintained.
Ensure that the NSIAC Initiative on SAMGs is maintained.

Many Licensees used the communications capabilities described in these assessments as part of the FLEX strategies.
As a minimum, configuration control and maintenance of the communications equipment need to be maintained as part of the FLEX program to satisfy the (C)(4) section of the rule. Part of the reason the NRC moved the communications requirements from App E to 50.155 was to avoid requiring licensees to include the beyond
-design-basis communications in their EP plans. This avoids issues with change control under 50.54(q) rather than 50.155(g).

Additionally, in each 8-calendar-year exercise cycle, nuclear  power reactor licensees shall vary the content of scenarios during exercises conducted under paragraph 2 of this section to provide the opportunity for the ERO to demonstrate proficiency in the key skills necessary to respond to the following scenario elements:
hostile action directed at the plant site, no radiological release or an unplanned minimal radiological release that does not require public protective actions, an initial classification of or rapid escalation to a Site Area Emergency or General Emergency, and integration of offsite resources with onsite response. The licensee shall maintain a record of exercises conducted during each 8-year exercise cycle that documents the content of scenarios used to comply with the requirements of this paragraph.
Each licensee shall conduct a hostile action exercise for each of its sites no later than December 31, 2015. The first 8-year exercise cycle for a site will begin in the calendar year in which the first hostile action exercise is conducted.
For a site licensed under 10 CFR part 52, the first 8-year exercise cycle begins in the calendar year of the initial exercise required by section IV.F.2.a of this appendix.

However, in November 2015 the NEI Nuclear Strategic Issues Advisory Committee (NSIAC) approved an Industry Initiative on SAMGs that requires each licensee to docket site- specific commitments concerning the updating these guidelines, and their consideration within plant configuration management processes, integration with other emergency response guideline sets and symptom-based EOPs, and validation.

V.B ., "Rule-making Scope", p - 56  V.C ., "Command and Control" - p 87 Reg Analysis, section 2.3 states: "The Commission concluded that the imposition of SAMG requirements was not warranted because it did not meet the substantial additional protection criteria under 10 CFR 50.109(a)(3).
Consequently, this regulatory analysis does not further evaluate SAMGs as proposed requirements in the final MBDBE Rule. Instead, SAMGs will continue to be implemented and maintained through a voluntary industry initiative as discussed in SRM-SECY-0065 and in Option  1."    Note that SRM
-SECY-15-065 included direction that SAMG oversight be included in the ROP: "The staff should update the Reactor Oversight Process to explicitly provide periodic oversight of industry's implementation of the SAMGs. NRC guidance should clarify how deviations or performance deficiencies would be addressed.
" Ensure that the NSIAC Initiative on SAMGs is maintained.

Individual licensee stations implemented and achieved compliance with Order EA-12-049 at different points in time and were not always consistent in site specific adoption of endorsed white papers or FAQs. The NEI 12-06 Revision Comparison provides section-by-section identification of changes in NEI 12-06 to support the user's effective and efficient identification of gaps for their resolution during implementation of 10 CFR 50.155.
The information captured in the Impact/Interpretation and Action columns is based upon an assumption that NEI 12-06 Revision 4 will be used for implementation of 10 CFR 50.155.
The NEI 12-06 Revision Comparison Matrix identifies changes in each section of the following endorsed revisions; NEI 12-06, Diverse and Flexible Coping Strategies (FLEX) Implementation Guide, Revision 0, August 2012  NEI 12-06, Diverse and Flexible Coping Strategies (FLEX) Implementation Guide, Revision 2, December 2015  NEI 12-06, Diverse and Flexible Coping Strategies (FLEX) Implementation Guide, Revision 4, December 2016  Changes in other versions of NEI 12-06 including the not-endorsed Revision 1 and Revision 3 are not specifically captured in the matrices. As such, the changes from Revision 1 are contained in the R-2 Change column unless the Revision 1 change was further altered or removed by the Revision 2 change. Similarly, the Revision 3 changes are contained in the R-4 change column. NEI 12-06 Sections with no changes from Revision 0 through Revision 4 are not listed in the Matrix. NEI 12-06 changes to format or spelling such as changing "n" to "N" or renumbering of footnotes are not shown. The FLEX Strategy Validation Revision Comparison is provided in a separate matrix to accommodate the initial guidance being a white paper in lieu of being included in NEI 12-06, Revision 0. This supplemental Matrix provides a table showing the significant changes made in the published versions of;  NEI FLEX Validation Process White Paper, Attachment to APC 14-17, July 18, 2014  NEI 12-06, Diverse and Flexible Coping Strategies (FLEX) Implementation Guide, Revision 2, December 2015, Appendix E  NEI 12-06, Diverse and Flexible Coping Strategies (FLEX) Implementation Guide, Revision 4, December 2016, Appendix E  An explanation of the information provided in each column of the matrix follows:  Section - Provides the NEI 12-06 Section number and title.

NEI FLEX FAQ Disposition Table provides a cross-reference to NEI 12-06 Section where the information was incorporated.
This table is provided as an aide to the user of the NEI 12-06 Revision Comparison Matrix. FAQ references that were incorporated into NEI 12-06 sections are included in individual Matrix cells and related FAQ references are also provided. These Incorporated FAQs and/or Related FAQs can be referenced to provide additional insights on the topic and its resolution.
Note that in all cases, it is the responsibility of every licensee to examine its licensing bases and determine what additional actions may be necessary to achieve full compliance with 10 CFR 50.155 including determination of the revision level of the implementing guidance. Summary of Major Gap Assessments/Recommended Actions The major gaps/recommended actions in the NEI 12-06 Revision Comparison Matrix include;  Validation Requirements including providing a basis for time sensitive actions performed more than 24 hours after the initiation of the event. (Section 3.2.1.7 and Appendix E)  Incorporation by reference of several supplemental guidance documents.
(Section 3.2.1.13)
Clarification on  minimum  quantities of  hoses  and  cables  to  be  maintained allowing  for  potential reduction in equipment.
(Section 3.2.2)
Clarification on minimum Spent Fuel Pool Cooling Strategy spray requirements allowing for potential reduction in equipment.
(Table 3-1, 3-2 and Appendix C, D)  Clarifications on alternate locations for instrument readings. (Section 5.3.3)
Clarifications to support using existing station processes to manage maintenance and testing.  (Section 11.5.2)  Clarifications to support managing out of service time including separating functional from protected 52 June 8, 17 NEI 17-03, [Rev A]  and using station corrective actions and work control processes.
(Section 11.5.3)  Clarification on Configuration Control to support long term sustainability of FLEX Program including FLEX Strategy change management.
(Section 11.8)
Removal of recommendation to maintain Final Integrated Plan (FIP) as a living document. (Section 13.2)
Addition of the reevaluated flooding hazard and seismic hazard for determining the adequacy of the FLEX Strategies.
(Appendix G and Appendix H)  USER NOTES  Due to the large size of this matrix, it has been formatted to extend across two adjacent facing pages.
Matrix provides description of changes in the progression of the revisions of NEI 12-06. The User enters in the left side column for each row that corresponds to their currently implemented FLEX Mitigating Strategies NEI revision level as well as adoption of endorsed white papers and FAQs. Then, using the information on the changes in each revision of NEI 12-06 and moving to the right, the user identifies the impact to their FLEX Mitigating Strategies and actions needed to close the gap in support of 10 CFR 50.155 implementation aligned with NEI 12-06 Revision 4. The gaps, impact and actions can be used to assist with the decision of whether to adopt a newer revision, or to develop a justification for use of an older revision. For example if a station's FLEX Mitigating Strategies were implemented using NEI 12-06 Revision 0, the aggregate of the changes in columns R-2 Change and R-4 Changes have the potential to  impact the FLEX Mitigating Strategies in achieving compliance with NEI 12-06, Revision 4 and the MBDBE. Potential impacts could be only administrative for the change in revision of the NEI 12-06 with no change in requirements, or no change in the net requirements between Revision 0 and Revision 4. Additionally, the potential impact could be none if the clarifications incorporated into NEI 12-06 are consistent or not more restrictive as adopted in site- specific FLEX implementation.

Impact/Interpretation Action  Clarification adding details  JLD-ISG-2012-01 R 2 points out that NEI 12-06 R 4 Section 3.2.1.7
.6 requires "Strategies that  have a time constraint to be successful should be identified and a basis provided that the time can reasonably be met. "  The ISG discusses the use of Level A or B validation as a method to address the "reasonably met" criteria for those tasks expected to be performed >24 hours after the initiation of the event that have a time constraint.
NEI 12-06 Appendix E step E.5.1.2 states in part "tasks performed greater than 24 hours after the event will not be time validated."
(Additional information on Validation provided in Appendix E)    The Validation guidance used may not have required validation of actions performed >24 hours after the event. Based on current guidance, review FIP timeline to verify time sensitive actions required >24 hours after the event were validated or a basis provided that the time can be reasonably met. Validation or some other basis may need to be provided for those that were no t time validated using a Level A or B validation process. Clarification None  This change formally incorporates all the industry white papers and technical papers into the NEI 12-06 guidance. Many licensee strategies adopted the white papers and docketed this information, the current FIPs and/or program document may refer to these as "white papers" and not formal guidance of NEI 12-06. There is no technical change in the individual white paper content, however, since the FIPs and/or program document may still refer to these positions as "white papers," these may require revision. Potential update to FIP and/or program document  Implementation of change control will vary dependent upon which revision of NEI 12-06 is being adopted. If NEI 12-06 R2 or R4 is adopted that incorporates the "white paper" the content of the white paper is no longer an 'alternate approach' that requires additional evaluation of applicability to facility.

Impact/Interpretation Action  New Guidance for performing Flooding Hazard evaluation The Mitigating Strategies Assessment (MSA) determines if the FLEX strategies can be implemented given the impact of the reevaluated flood hazard information.
If it is determined the FLEX strategies cannot be implemented, the MSA considers other options such as plant modifications, modifications to strategies or different mitigation strategies.
The MSA process provides multiple assessment Paths to accommodate site specific differences between their design basis flood hazard and their reevaluated flood hazard. Implementation of any FLEX Strategy changes or facility changes (physical or technical basis) indicated by the MSA would be governed by Section 11.8, Configuration Control. The MSA document itself is not required to be maintained.
However, Section 11.8.1 requires the basis of the FLEX Strategies be maintained and Section 11.8.2 requires configuration control processes will be used to ensure changes to the facility will not adversely impact the FLEX Strategies.
As such, ensuring the controlling performance criteria or margin for flood protection features that were established during the MSA are not reduced via replacement and/or plant modification will provide the on- going basis that the FLEX Strategies are not impacted by the reevaluated flood hazard. Validate site's Flooding MSA has been performed as described in Appendix G. If the MSA concluded the FLEX Strategies can be implemented without change due to the impact of the reevaluated flood hazard information, a basis documentation update will be required. If the MSA concluded a change is needed, the change would be implemented with station procedures and as described in Section 11.8 including the determination if the change can be made without NRC approval. Implementation of these changes is required to achieve compliance with the implementation of 10 CFR 50.155.

128 June 8, 17    NEI 16-05, [Rev A]    8 NEI 12-01 COMPARISON Introduction To assist in implementing 10 CFR 50.155, a gap assessment of NEI 12-01, Revision 0 has been performed.
That process involved preparing a matrix to facilitate review of the following references to assess potential gaps that a licensee may encounter during implementation of 10 CFR 50.155 and identify the recommended actions to close those gaps:  10 CFR 50.155 sections applicable to Beyond Design Basis (BDB) event response staffing and communications capabilities including the applicable portions of the associated statements of consideration (ADAMS Accession No. ML16292A026).
Regulatory Guide (RG) 1.228 Revision 0, Integrated Response Capabilities for Beyond
-Design-Basis Events, endorses NEI 12
-01 Revision 0 as an acceptable method to assess staffing and communication capabilities and needs when responding to a beyond-design-basis event. There are no exceptions or clarifications to NEI 12
-01 Revision 0 guidance in RG 1.228. Therefore, there are no additional gaps specific to RG 1.228 that need to be addressed for compliance with staffing and communications requirements of the rule.
NEI 12-01 Revision 0, Guidelines for Assessment Beyond Design Basis Accident Response Staffing and Communications Capabilities.
Other NRC requirements or guidance supporting the development of NEI 12-01 Revision 0 as listed in the "Other Requirement or Guidance" column of the gap assessment matrix.
All power reactor licensees and holders of Construction Permits in Active or Deferred Status received a 10 CFR 50.54(f) letter regarding NTTF recommendation 9.3, dated March 12, 2012. See Attachment 6 of the 10 CFR 50.54(f) letter for a listing of addressees. In response to the March 12, 2012 letter, addressees performed staffing and communication assessments using the guidance provided in NEI 12-01 Revision 0. 10 CFR 50.155 does not require these assessments to be re
-performed, but addressees need to review commitments made in those assessment submittals and determine which of the commitments are necessary for rule compliance and need to be treated as obligations. In addition, the following need to be maintained per the change control process in 10 CFR 50.155(g):  Documentation of sufficient staffing to support the strategies required by 10 CFR 50.155(b)(1) through (b)(3). Documentation of the communications capability to support the strategies required by 10 CFR 50.155(b)(1) and (b)(2).
Summary of Major Gap Assessments
/ Recommended Actions  NOTES:  1. 10 CFR 50.155(b)(5) requirements for staffing capabilities are applicable to the requirements of 10 CFR 50.155(b)(1) through (b)(3).
: 2. 10 CFR 50.155(c)(4) requirments for communications capabilities are applicable to the requirements of 10 CFR 50.155 (b)(1) and (b)(2). 3. Although the requirements for communications capabilities contained in 10 CFR 50.155(c)(4) are not applicable to paragraph 10 CFR 50.155(b)(3) (EDMGs), all licensees have existing communications capabilities supporting EDMGs at the guidance level. See the B.5.b Phase 1 guidance letter dated February 25, 2005, Items B.1.i and B.2.b. Further details are available in NUREG 0800, Standard Review Plan, Section 19.4, Acceptance Criteria Item 12.

From the Statement of Considerations, there is no intent to require current licensees to re-perform those staffing assessments as part of 10 CFR 50.155 implementation.
However, current licensees that performed these staffing assessments should maintain any commitments made in the responses submitted under the 10 CFR 50.54(f)) letter required responses.
Changes to those commitments should follow the commitment change process established by the Licensee. Additionally, Licensees should address the potential impact of changes to the 10 CFR 50.155(b)(1) through (b)(3) mitigation strategies on the staffing assessments that were performed to ensure that staffing remains adequate. The need for this evaluation could come about in one of several ways:  1. Changes to the 10 CFR 50.155(b)(1) through (b)(3) mitigation strategies that involve additional actions, action complexity or that change the sequence of required actions. 2. Changes to minimum staffing requirements that impact the number of staff available to perform required actions.

There are no direct training requirements associated with communications equipment defined in 10 CFR 50.155. However, to the extent that the deployment and use of communications equipment is necessary to successfully implement the strategies required by 10 CFR 50.155(b)(1) through (b)(3), training on communications location, deployment and use should be considered under 10 CFR 50.155(d).
NOTES:
177 June 8, 17 NEI 17-03, [Rev A]  9 NEI 13-06 COMPARISON Introduction To assist in implementing 10 CFR 50.155, a gap assessment of NEI 13-06, Revision 1 has been performed.
That process involved preparing a matrix to facilitate review of the following references to assess potential gaps that a licensee may encounter during implementation of 10 CFR 50.155 and identify the recommended actions to close those gaps . NRC  RG 1.228 "Integrated Response Capabilities for Beyond Design Basis Events  identifies methods and procedures the NRC considers acceptable for compliance with 10 CFR 50.155 "Mitigation of Beyond-Design-Basis Events." The staff position is that NEI 13-06 provides an acceptable method for enhancing the on-site emergency response capabilities for beyond-design-basis events through training, drills or exercises, and facilities and equipment to support a multi-unit event response. The NRC position does not include any exceptions or clarifications.
It is important to note that Revision 1 of NEI 13-06 was drafted based on an early version of the proposed 10CFR50.155 rule. As such, some sections of NEI 13-06 address proposed requirements of the early rule draft that do not exist in the final version. In particular, both the Multi Source Term Dose Assessment capability (MSTDA) and Severe Accident Mitigation Guideline (SAMG) requirements were removed from the draft final rule language. These capabilities have been implemented through the licensee Regulatory Commitment process,(i.e. process described in NEI 99
-04)  and are managed according to that process. It should also be noted that NEI 12-06 has been revised since the publication of NEI 13-06. Changes to 12-06 have made some of the discussion in the Executive summary of 13-06 obsolete. Specifically, the sentence in the Executive Summary that quotes from NEI 12-06, Section 11.6, "Where appropriate, the integrated FLEX drills should be organized on a team or crew basis and conducted periodically; with all time-sensitive actions to be evaluated over a period of not more than eight years." This quote is no longer accurate, as it was removed in Revision 4 of 12-06. NEI 12-06 now refers back to 13-06 for guidance related to drills, noting that Industry guidance for conducting FLEX drills is provided in NEI 13-06. Summary of GAP Assessment/Recommended Actions The recommended actions identified by the gap assessment review are provided in the "Gap Assessment
/ Recommended Action" column of the matrix and are summarized below.
: 1. To meet the 13
-06 guidance a site must have the capability to predict offsite doses (including dose from multiple source terms) during an event involving an extended loss of all AC power affecting all onsite units. Previously, the commitment to perform this did not require the assumption of an extended loss of AC power. Even though not required by the rule, licensee regulatory commitments include the capability to predict dose from multiple source terms.
: 2. An ERO rol e identified as "Ultimate Decision Maker" is defined. This individual is assigned authority and responsibility for providing overall direction on the implementation of EOPs, FSGs, EDMGs and SAMGs for a unit or set of units. 3. On an eight (8) year frequency, sites must conduct drills demonstrating BDB strategies (including communications capabilities), including;
: a. A drill that demonstrates the integrated use of FLEX strategies under the control of an Abnormal Operating Procedure (AOP) or Emergency Operating Procedure (EOP), as appropriate to the postulated scenario.
178 June 8, 17 NEI 17-03, [Rev A]    b. A drill that demonstrates the transition from a controlling AOP, EOP or Extensive Damage Mitigation Guidelines (EDMG) into Severe Accident Management Guidelines (SAMGs), and the selection of appropriate severe accident management strategies.
Even though not required by the rule, licensee regulatory commitments include SAMGs to be integrated with the EOP network. c. A drill that demonstrates the use of EDMG strategies.
: d. A drill or drills to demonstrate the capability to utilize equipment necessary to implement each strategy for responding to a beyond design basis event or severe accident. It is important to note that while it is acceptable to use an EP exercise to accomplish the new drill requirements, it is recommended that exercises not be used to meet these requirements.
Graded exercises serve a specific purpose to meet the regulatory required emergency planning requirements.
Combining BDB drills with a graded exercise could lead to confusion and conflicts that interfere with objectives of either or both of the activities.

/ Recommended Action SECTION 1 INTRODUCTION None None SECTION 2 MULTI-UNIT DOSE ASSESSMENT Section IV Public Comment and Changes to the Rule provides the NRC response to comments and the draft rule. This requirement was removed from the final language as the NRC concluded that there is not sufficient risk associated with events that challenge multiple source terms to find that substantial additional protection to public health and safety could be achieved through the imposition of the subject requirements All sites should have Multi Source Term Dose Assessment (MSTDA) capability in place as a result of the industry-wide commitment.
Controls to ensure this capability is maintained are typically managed through the Site commitment management program. Section 2.3.1 of 13-06 states that the capability should be available to support responses during events both within and beyond the plant design basis. In particular, the capability should exist to project offsite doses during an extended loss of AC power affecting all onsite units. There exists a potential gap in that not all licensees provide this capability as part of their implementation of the multi-source term dose assessment commitment.
This may require the addition of backup power to onsite dose assessment computing platforms or ensuring the availability of computing platforms away for the site. Specific actions include;  1) Maintain MSTDA Commitment consistent with Licensee specific letter, and 2 confirm capability to project offsite doses during an extended loss of AC power (ELAP) 181 June 8, 17 NEI 17-03, [Rev A]  10CFR 50.155 Section Other Requirement or Guidance  NEI 13-06 Section Guidance Statements of Consideration (ADAMS Accession No. ML16292A026)

/ Recommended Action None The NEI BDB Program Manual template is intended to be the location to place the required material. SECTION 3 TRAINING The SOC recognizes that training exists for elements of the rule that have already been implemented.
The SOC explains that the SAT process be used for any "newly identified training requirements supporting the effective use of the strategies and guidelines that are required by this rule". Training on new requirements identified during the implementation of the MBDBE rule are required to be performed per the SAT process. However, elements already covered under other NRC regulations can be addressed in a non-SAT training program that is acceptable for meeting that specific regulatory requirement (e.g., 10 CFR part 50, appendix E, section IV.F) 11.6 of NEI 12-06 states; "ANSI/ANS 3.5, Nuclear Power Plant Simulators for use in Operator Training" certification of simulator fidelity (if used) is considered to be sufficient for the initial stages of the beyond-design-basis external event scenario until the current capability of the simulator model is exceeded. Full scope simulator models will not be upgraded to accommodate FLEX training or drills." As noted in the interpretation column, full scope simulators are not required to be upgraded to accommodate FLEX training or drills. As such, there should be no gap to address within simulator capabilities.

211 June 8, 17 NEI 17-03, [Rev A]    10 NEI 14-01 ICOMPARISON Introduction An assessment of NEI 14-01, Revision 1 guidance against the requirements in 10 CFR 50.155 was performed to assist in implementing the new rule. T The assessment involved preparing a matrix to facilitate review of the following references to assess potential gaps that a licensee may encounter during implementation of 10 CFR 50.155 and identify the recommended actions to close those gaps:  10 CFR 50.155 sections applicable to Beyond Design Basis (BDB) event integrated response capabilities including the applicable portions of the associated statements of consideration.
NEI 14-01 Revision 1, Emergency Response Procedures and Guidelines for Beyond Design Basis Events and Severe Accidents.
Other NRC requirements or guidance supporting the development of NEI 14-01 Revision 1 as listed in the "Other Requirement or Guidance" column of the gap assessment matrix. The new rule limits the scope of the integrated response capability to the strategies, guidelines, and alternative approaches under § 50.155(b).
During the development of the rule, other guideline sets were considered for inclusion within the integrated response capability.
The guideline sets considered included  fire  response  procedures,  alarm  response procedures, and abnormal operating procedures (AOPs). These guideline sets are not included in the final rule. In keeping with the basis for a functional integration of the strategies and guidelines with EOPs, 10 CFR 50.155 requires  that  the  §  50.155(b)  strategies,  guidelines,  and  alternative approaches be  integrated "with  the Emergency Operating Procedures (EOPs)." The rule language is intended to communicate the NRC's expectation that the EOPs retain their role as the primary means of directing emergency operations and that the strategies and guidelines that are required under this rule are integrated with EOPs to support their implementation.
NEI 14-01 provides guidance for ensuring that EOPs, EDMGs, FSGs and SAMGs are integrated in a cohesive, effective and usable manner. It also addresses recommendations for the development of mitigation and management guidelines, and command and control structures, for responding to beyond design basis events and severe accidents.
As a result of the rulemaking the PWR Owner's Group in conjunction with the BWR Owner's Group developed a project plan to provide high level guidance to the industry. There are two major tasks of the project:  Revise Procedure Usage Standard for Response to Plant Transients Develop Beyond Design Basis Events Guideline Standard  Based upon the timeline associated with the project plan the guidance should be available for implementation when the rule becomes effective.
Summary of Major Gap Assessments
/ Recommended Actions  The recommended actions identified by the gap assessment review are provided in the "GAP Assessment

====3.2.2 Principles====
for SAMGs The following principles should be applied to the development and implementation of SAMGs:
* Site-specific strategies and implementing methods should be based upon existing plant systems, structures and components, and available portable equipment.
Modifications to the plant design are permitted but not required.
* Any plant system, structure or component, and available portable equipment, may be used to implement an accident management strategy, irrespective of safety classification or other design-related criteria. In addition, the normally-applied controls on the use or configuration of a plant system, structure or component may be altered if necessary to implement a strategy (e.g., establishing a system lineup not described in the facility licensing basis).
* The inclusion of a plant system, structure or component within a severe accident management strategy implementing method does not impose any additional design or maintenance
-related requirements on that item (i.e., beyond those associated with the existing specifications and programs).
For example, the design-basis safety classification of a plant system, structure or component - safety-related, important to safety, etc. - is not changed because of its employment within a strategy implementing method.
* Strategies should reflect a best-estimate understanding of accident progression and consequences.
* SAMG entry conditions and operator actions should be symptom-based and clearly linked to specific plant parameters.
Identification of the initiating event should not be required in order to determine which strategy should be implemented.
* The best possible operational guidance should be specified to restore and maintain key plant parameters within limits which define controlled and stable plant conditions, irrespective of licensing or design basis assumptions or commitments.

* Operator actions and decision-making criteria (e.g., a parameter value or trend that prompts a given action) should be determined using best-estimate assumptions and calculations, irrespective of licensing or design basis analytical assumptions and calculations.
* The capability to assess decision-making criteria (e.g., a parameter value or trend that prompts a given action) should accommodate the use of any available indications.
Potential uncertainties in instrumentation readings caused by anticipated severe accident environmental conditions should be considered during the development of decision-making criteria.

& Validation
* Guidelines for responding to a severe accident should be verified and validated in accordance with an applicable fleet or site procedure development process.
* Verification and validation processes should assess the technical accuracy and adequacy of the instructions, and the ability of personnel to follow and implement them.
* Guidelines should be verified and validated using existing plant capabilities.
Increasing the capability of the plant-referenced simulator to specifically model the conditions of the reactor core or stored spent fuel during a beyond design basis event or severe accident is not required.
* The verification and validation process should accommodate the differences between non-severe and severe accident conditions.
* Due to the unbounded nature of severe accident sequences and potential resulting conditions, a limited number of scenarios should be developed for the SAMG validation process (i.e., a sample group). 3.2.3.3 Document Updating & Maintenance
* Review, revision, approval, distribution and placement of SAMGs should be performed in accordance with the appropriate fleet or site document control process.
* A revision to the applicable generic severe accident technical guidelines should be assessed and implemented within 2 refueling outages or 3 years of the publication date, whichever is greater. 3.2.3.4 User Aids
* The development, verification and validation of user aids should be consistent with applicable fleet and/or site policies.

It is not necessary to create a new ERO position or title.
* The Shift Manager should serve as the UDM during the implementation of Abnormal Operating Procedures (AOPs) and Emergency Operating Procedures (EOPs).
* Following a transition into Severe Accident Management Guidelines (SAMGs), the UDM authority and responsibilities may be retained by the Shift Manager, or transferred to an UDM-qualified individual located in another facility.
* Following the transfer of the UDM function to an ERO position-holder located outside the Control Room (e.g., in the TSC), the support staff assisting with strategy evaluation and selection should include at least one member who holds an active SRO license, or has successfully completed an SRO licensing or certification program in the past, applicable to the affected onsite unit(s).
* Following an event associated with loss of large areas of the plant due to explosions or fire, and causing a loss of the Control Room command and control structure, a procedure or guideline should describe the position(s) that could assume command and control of the event response. Due to the contingent and short-term nature of this assignment, and the initial focus on implementation of pre-planned EDMG strategies, it is not necessary for this position(s) to hold a UDM qualification.
A procedure or guideline should specify how command and control are subsequently transferred to a position which does possess a UDM qualification.
* The UDM is able to direct changes to a pre-planned fire response strategy if necessary to support implementation of an accident or event mitigation or management strategy
* The UDM assignment(s) should be consistent with the licensee's staffing assessments performed in accordance with NEI 12-01
* The authorities and responsibilities necessary to coordinate the acquisition and delivery of offsite resources are defined.
* At sites operating within a fleet structure, fleet-level command and control capabilities should be integrated into the licensee's command and control structures if such support will be relied upon during a beyond design basis event or severe accident.
* Specific UDM authorities and/or responsibilities that may be delegated, if any, are defined.
* Where appropriate, procedures and guidelines should contain guidance concerning the implementation of emergency response actions in accordance with 10 CFR 50.54(x) and the associated approval of such actions in accordance with 10 CFR 50.54(y).

227 June 8, 17 NEI 17-03, [Rev A]    11 RG 1.226 TO JLD-ISG 1201-01 COMPARISON
 
== Introduction:==
 
RG 1.226 will generally allow use of the same actions used by utilities for compliance with the NRC order EA 049. On December 15, 2016, NRC issued SECY-16-0142, Draft Final Rule - Mitigation of Beyond-Design-Basis Events (RIN 3150-AJ49) to obtain Commission approval to publish a final rule that establishes requirements for nuclear power reactor licenses and applicants.
As part of the draft final rule package, a pre-decisional version of Regulatory Guide (RG) 1.226, "Flexible Mitigation Strategies for Beyond-Design-Basis Events" was also issued. RG 1.226 endorses, with clarifications, the methods and procedures promulgated by the Nuclear Energy Institute (NEI) in technical document NEI 12-06, "Diverse and Flexible Coping Strategies (FLEX) Implementation Guide", Revision 4, as a process the NRC considers acceptable for meeting, in part, the regulations in 10 CFR 50.155. Additionally, RG 1.226 provides guidance in areas that are not covered in NEI 12-06 for meeting 10 CFR 50.155. On February 8, 2017, NRC issued Interim Staff Guidance (ISG) JLD-ISG-2012-01 Revision 2, "Compliance with Order EA-12-049, Order Modifying Licenses with Regard to Requirements for Mitigation Strategies for Beyond- Design-Basis Events". JLD-ISG-2012-01 endorses, with exceptions, additions and clarifications, the methodologies described in the industry guidance document, Nuclear Energy Institute (NEI) 12-06, Revision 4 as one acceptable approach for satisfying Order EA-12-049 requirements.
Summary of Major Gap Assessments/Recommended Actions:
Since both NRC guidance documents endorse, with exceptions, additions and clarifications, the same industry guidance document for satisfying essentially the same set of NRC requirements, it would be expected that the endorsements should be consistent, and for the most part they are. The table below summarizes the significant gaps identified in a detailed comparison of RG 1.226 with JLD-ISG-2012-01 Revision 2. Description of Difference Impact to Licensees Recommended Resolution RG 1.226 endorses NEI 12-06, Revision 4, but its implementation section allows use of other NRC acceptable methods NEI 12-06 revision 0 and 2 do not include all the provisions included in revision 4 relative to Change Control, MSA and Out of service time. Some plants that responded under licensing conditions for compliance with mitigating strategies actions per NEI 12
-06, revision 0 will have to request approval to upgrade to revision 2 or 4. Best Option: Comply with NEI 12- 06 revision 4  Alternate Option: Document clearly which sections of which revision the site is complying with and how that is consistent with the remainder of the selected compliance version of NEI 12-06. An example is; JLD-ISG-2012-01 Rev 2 did not take a position on the acceptability of 11.8.3.a.iii for change control.
 
228 June 8, 17 NEI 17-03, [Rev A]  The ISG recognizes that FLEX equipment may be pre-staged for up to 45 days to reduce the risk of maintenance or outage activities.
All other instances of unavailability due to the lack of reasonable protection is limited to 14 days. The During the ISG public comment period, the NRC Staff requested stakeholder feedback on the allowance of 45 days for reasonable protection.
From the comments received, the NRC Staff concluded that the 45 day Best Option:  Utilize NEI 06, Revision 4 guidance Alternate Option: Recognize and 229 June 8, 17 NEI 17-03, [Rev A]    Description of Difference Impact to Licensees Recommended Resolution RG 1.226 discussion on this topic only includes the 14 day allowed outage time with no mention of the exception for 45 days if deployed to reduce the risk of maintenance or outage activities.
However, in the NRC Staff's concluding position, the Staff states that Section 11.5.4 provides an acceptable method for controlling unavailability of the equipment to satisfy that element of reasonable protection. Note there is a distinction for deployed equipment for maintenance or outage activities with regard to reasonable protection.
allowance was acceptable with no change required to the ISG because NEI 12-06 Rev 4 already incorporates this guidance. The NRC Staff felt it important enough to differentiate the two separate allowed outage times for reasonable protection of equipment in the ISG, but makes no such distinction in RG 1.226. This may lead to confusion during FLEX inspections.
communicate the difference at the MBDBEE Rulemaking workshop and emphasize that RG 1.226 endorses all of NEI 12-06 Rev 4 Section 11.5.4 which includes the 45 day allowed outage time for equipment protection when used to reduce  risk of maintenance or outage activities Susquehanna Steam Electric Station is included as a separate bullet in  the ISG but combined with the bullet for Salem Nuclear Generating Station in RG 1.226 No technical impact. Might be harder for someone to find it when needed.
None RG 1.226 adds a new Section 7, Coordination with Severe Accident Management Guidelines.
Section 7 in the ISG is Section 8 in RG 1.226. None. This added section endorses, with no exceptions, clarifications or additions, NEI 12- 06 Rev 4 Section 3.2.10 and 11.4. Recognize and communicate the difference at the MBDBEE Rulemaking workshop and emphasize that RG 1.226 endorses NEI 12-06 Rev 4 Section 3.2.10 and 11.4. (reference SRM-COMSECY  User's Notes:  Due to the large size of this matrix, it has been formatted to extend adjacent facing pages. A detailed and systematic review of the two documents was performed to identify any substantial differences between them.
The results of the gap analysis determined that the substantial differences are limited to the first two items documented in the Table above. The following table contains only the changes identified in the review that might require an evaluation by utilities.
The gap analysis showing all the results is not included herein due to its size and expected limited use by our members, but it is available on NEI's Member Website as Addendum 1 to NEI 17-03.
230 June 8, 17 NEI 17-03, [Rev A]  ISG-2012-01 rev 2 RG 1.226 RATIONALE 1. Order EA-12-049 requires that licensees shall develop, implement, and maintain guidance and strategies to maintain or restore core cooling, containment, and SFP cooling capabilities following a beyond-design-basis external event. The three-phase approach described in the order is a conceptual framework built upon the need for a licensee to address challenges to the safety functions when they occur, using installed structures, systems, and components for a coping period until portable mitigating equipment can be used to address those challenges.
The finite level of resources on site makes the arrangement of offsite resources necessary to address potential  widespread catastrophes, such as the occurrence at Fukushima, where the restoration of offsite power is precluded by damage. Licensees' emergency operating procedures will provide the command and control  structure in response to beyond-design-basis external events. Additional guidance documents will be developed for deployment of the FLEX strategies in support of the emergency operating procedures.
: 2. The NRC has previously provided regulatory guidance for the development, implementation, and maintenance of guidance and strategies intended to maintain or restore core cooling, containment, and SFP cooling capabilities under the circumstances associated with the loss of large areas of the plant due to explosions or fire. This was done through the endorsement of NEI 06-12, "B.5.b Phase 2 & 3 Submittal Guideline,"
Revision 2, issued December 2006 [Reference 43], for holders of and applicants for operating licenses issued under 10 CFR Part 50, and Revision 3 of NEI 06-12, issued July 2009 [Reference 44], for holders of and applicants for combined licenses under 10 CFR Part 52. This regulatory guidance continues to provide an acceptable means of meeting the requirement to develop, implement, and maintain the necessary guidance and strategies for the subset of beyond-design-basis external events addressed by 10 CFR 50.54(hh)(2).
Reason for Issuance One of the primary lessons learned from the accident at the Fukushima Dai-ichi nuclear power plant was the significance of the challenge presented by a loss of multiple safety-related systems following the occurrence of a BDBEE. In the case of the Fukushima Dai-ichi accident, the loss of all alternating current power led to loss of core cooling, and ultimately to core damage and a loss of containment integrity.
The design basis for U.S. nuclear plants includes bounding analyses with margin for external events expected at each site. Extreme external events (e.g., seismic events, external flooding, etc.) beyond those accounted for in the design basis, while unlikely, could present challenges to nuclear power plants. In response to lessons learned from the Fukushima Dai-ichi accident, the NRC promulgated 10 CFR 50.155, "Mitigation of Beyond-Design-Basis Events," to improve the capability of nuclear power plants to address BDBEEs. As one method of addressing the challenges that may be presented by these types of events, this RG endorses, with clarifications as detailed in this RG, the principles and processes in NEI 12-06, Revision 4, as acceptable for use by applicants and licensees to define and deploy strategies that will enhance their ability to cope with conditions resulting from BDBEEs.
231 June 8, 17 NEI 17-03, [Rev A]  RG 1.226 Differences Impact of Change 1. RG 1.226 changes the reference from EA-12-049 to 10 CFR 50.155, 2. Both documents endorse NEI 12-06, revision 4. 3. ISG notes that B5b (50.54)(hh)(2) requirements are not contained in the guidance of NEI 12-06. (Note that 50.155 will now incorporate 50.54(hh)(2) within its scope) 1. Regulation documentation change. Editorial, no evaluation needed. 2. Each site will need to evaluate NEI 12-06 rev 4 for changes that may be required. Note that ISG-2012-01 allowed for previous revisions of NEI 12-06 to be acceptable means. This remains an option as outlined below in Implementation section. 3. Sites should verify that they are in compliance with regulatory guidance pertaining to program currently known as B5b or 50.54(hh)(2).( reference phase I guidance letter of 2/25/2005, NEI 06
-12, Revision 2, and SRP 19.4)
 
232 June 8, 17 NEI 17-03, [Rev A]  ISG-2012-01 rev 2 RG 1.226 RATIONALE (continued)
: 3. The approach described in NEI 12-06, Revision 4, for development, implementation, and maintenance of mitigating strategies for beyond-design-basis external events provides a framework and methodology for such strategies to address those events that are not covered within the requirements of 10 CFR 50.54(hh)(2), subject to the exceptions, additions, and clarifications in the enclosure to this ISG. 4. The approach described in NEI 12-06, Revision 4, and its Section H.4.5 for the performance of assessments of the mitigating strategies under the reevaluated seismic and flooding hazards developed in response to the March 12, 2012, 50.54(f) letter provides an appropriate methodology for licensees to address the reevaluated seismic and flooding hazards in a manner that aligns with the proposed mitigation of beyond-design-basis events rulemaking.
Continued from previous page APPLICABILITY This ISG shall remain in effect until it has been superseded, withdrawn, or incorporated into a regulatory guide or the Standard Review Plan (SRP). GUIDANCE As discussed above, this ISG is applicable to holders of power reactor operating licenses, construction permits, or combined licenses. The NRC staff considers that the development, implementation, and maintenance of strategies and guidance in conformance with the guidelines provided in NEI 12-06, Revision 4, are an acceptable means of meeting the requirements of Order EA-12-049, subject to the exceptions, additions, and clarifications in the enclosure to this ISG. However, NRC endorsement of NEI 12-06, Revision 4, does not imply NRC endorsement of references listed in NEI 12-06, Revision 4. Applicability This RG applies to applicants and licensees subject to 10 CFR Part 50, "Domestic Licensing of Production and Utilization Facilities,"
and all applicants and licensees for a power reactor combined license under 10 CFR Part 52, "Licenses, Certifications, and Approvals for Nuclear Power Plants" (Ref. 3). Applicable Regulations 10 CFR 50.155, "Mitigation of Beyond-Design-Basis Events," requires nuclear power reactor licensees to develop, implement, and maintain an integrated response capability that includes strategies and guidelines to mitigate a Beyond-Design-Basis External Event (BDBEE) 233 June 8, 17 NEI 17-03, [Rev A]  RG 1.226 Differences Impact of Change Continued from previous page Continued from previous page 1. Issuance of the RG will cause the ISG to be withdrawn 3 years after the Rule is in effect. 2. ISG endorses NEI 12-06, rev 4. RG-1.226 also endorses rev 4 of NEI 12-06 (but not in this section). 1. Evaluation will be necessary to ensure compliance with the RG 2. Need to understand how order inspections will occur if scheduled after ISG is no longer in effect. The population that could be impacted is small because of the ISG will remain in effect for 3 years after the Rule is effective.
 
234 June 8, 17 NEI 17-03, [Rev A]  12 RG 1.227 TO JLD-ISG-2012-03 COMPARISON Introduction
:  RG 1.227 will generally allow use of the same actions used by utilities for compliance with NRC order EA-12-051. On December 15, 2016, NRC issued SECY-16-0142, Draft Final Rule - Mitigation of Beyond-Design-Basis Events (RIN 3150-AJ49) to obtain Commission approval to publish a final rule that establishes requirements for nuclear power reactor licenses and applicants.
As part of the draft final rule package, a pre-decisional version of Regulatory Guide (RG) 1.227, "Wide Range Spent Fuel Pool Level Instrumentation" was also issued. RG 1.227 endorses, with clarifications, the methods and procedures promulgated by the Nuclear Energy Institute (NEI) in technical document NEI 12-02, "Industry Guidance for Compliance with  NRC Order EA-12-051, 'To  Modify Licenses with Regard to Reliable Spent Fuel Pool Instrumentation'", Revision 1, as a process the NRC considers acceptable for meeting, in part, the regulations in 10 CFR 50.155. Additionally, RG 1.227 provides guidance in areas that are not covered in NEI 12-02 for meeting 10 CFR 50.155. On August 29, 2012, NRC issued Interim Staff Guidance (ISG) JLD-ISG-2012-03 Revision 0, "Compliance with Order EA-12-051, Reliable Spent Fuel Pool Instrumentation".
JLD-ISG-2012-03 endorses, with exceptions, additions and clarifications, the methodologies described in the industry guidance document, Nuclear Energy Institute (NEI) 12-02, Revision 1 as one acceptable approach for satisfying Order EA-12-051requirements.
Summary of Major Gap Assessments
/ Recommended Actions:  Since both NRC guidance documents endorse, with exceptions, additions and clarifications, the same industry guidance document for satisfying essentially the same set of NRC requirements, it would be expected that the endorsements should be consistent, and for the most part they are. A detailed and systematic review of the two NRC documents was performed and the differences are primarily editorial, changing the reference from order EA-12-051 (to be withdrawn) to the rule 10CFR50.155.
There is, however, one difference with greater significance.
The Applicable Regulations section of RG 1.227 explains a 10 CFR 50.155(f) requirement that each licensee provide reliable means to remotely monitor wide range water level for each spent fuel pool at its site until five years have elapsed since all of the fuel within that spent fuel pool was last used in a reactor vessel for power generation. . Paragraph 50.155(f) removes the requirement for operating nuclear power plants to provide wide
-range spent fuel pool level monitoring capabilities for spent fuel pools that contain only fuel greater than five years old.
This condition typically exists at plants with multiple spent fuel pools that use only one of the pools for freshly discharged fuel.
Paragraph 50.155(a)(2)(i) removes the requirement for wide
-range spent fuel pool level monitoring capabilities for all spent fuel pools at a nuclear power plant that has permanently ceased operation and removed all fuel from the reactor vessel once the NRC has docketed the appropriate certifications without regard to the age of the fuel in the pools.
User's Notes:  A detailed and systematic review of the two documents was performed to identify any substantial differences between them. The results of the gap analysis determined that the substantial differences are limited to the item documented above.
The following table contains only the changes identified in the review that might require an evaluation by utilities.
The gap analysis showing all the results is not included herein due to its size and expected limited use by  our  members,  but  it  is  available  on  NEI's  Member  Website  as  Addendum  2  to  NEI  17-03.
235 June 8, 17 NEI 17-03, [Rev A]  ISG-2012-03 RG 1.227 APPLICABILITY This ISG shall remain in effect until it has been superseded, withdrawn, or incorporated into a regulatory guide or the standard review plan. GUIDANCE This ISG is applicable to holders of power reactor operating licenses, construction permits, and combined licenses.
The NRC staff considers that the methodologies and guidance in conformance with the guidelines provided in NEI 12-02, Revision 1, subject to the clarifications and exceptions in Attachment 1 to this ISG, are an acceptable means of meeting the requirements of Order EA-12-051. NEI 12-02, Revision 1 references other documents, but the NRC's endorsement of NEI 12-02, Revision 1 in this ISG should not be considered an endorsement of any of the referenced documents.
Applicability This RG applies to applicants and licensees subject to 10 CFR Part 50, "Domestic Licensing of Production and Utilization Facilities,"
and all applicants and licensees for a power reactor combined license under 10 CFR Part 52, "Licenses, Certifications, and Approvals for Nuclear Power Plants" (Ref. 3). Applicable Regulations 10 CFR 50.155(f) requires each licensee to provide reliable means to remotely monitor wide range water level for each spent fuel pool at its site until five years have elapsed since all of the fuel within that spent fuel pool was last used in a reactor vessel for power generation.
