FAQ Number 06-0008 FAQ Revision 7 FAQ Title Alternative Method for Fire Protection Engineering Analyses Page 1 of 10 FAQ 06-0008 Engineering Analyses Rev 7 - changes accepted.doc Plant: Harris Date:10/9/07 Contact: Jeff Ertman Phone: 919-546-3681 Email:jeffrey.ertman@pgnmail.com Distribution: (NEI Internal Use) 805 TF FPWG RATF RIRWG BWROG PWROG Purpose of FAQ: The purpose of FAQ 06-0008 is to provide a method for the use of fire protection engineering analyses post-transition to address NFPA 805 Chapter 3 requirements. Currently, licensees may self approve these evaluations under the existing fire protection license conditions. The method discussed in this FAQ will be submitted for approval as part of the transition license amendment request (LAR). The method to be submitted in the LAR is to allow fire protection engineering analyses to address NFPA 805 Chapter 3 requirements for deviations from the codes, standards, and listings referenced in NFPA 805. Post-transition, licensees will use this method to self approve acceptable fire protection engineering analyses.
Is this Interpretation of guidance? Yes / No Proposed new guidance not in NEI 04-02? Yes / No Details: NEI 04-02 guidance needing interpretation (include section, paragraph, and line numbers as applicable):
Sections 2.3, 2.4, 4.3.1, 4.6.1, 5.3.2, Appendix H, and Appendix I of NEI 04-02 Revision 1.
Circumstances requiring guidance interpretation or new guidance: Risk-informed, performance-based fire protection engineering analyses are an acceptable alternative to the deterministic approaches in NFPA 805 Chapter 4. Risk-informed, performance-based fire protection engineering analyses may also be needed to document the acceptability of fire protection systems and features addressed in NFPA 805 Chapter 3 sections. Current licensing basis allows flexibility to use performance-based technical analysis per Generic Letter 86-10. An approach using these types of analyses is needed to allow this flexibility following tr ansition to NFPA 805.
Detail contentious points if licensee and NRC have not reached consensus on the facts and circumstances:
The fire protection program elements and minimum design requirements of NFPA 805 Chapter 3 may be subject to the performance-based methods permitted elsewhere in NFPA 805 per 10 CFR FAQ Number 06-0008 FAQ Revision 7 FAQ Title Alternative Method for Fire Protection Engineering Analyses Page 2 of 10 FAQ 06-0008 Engineering Analyses Rev 7 - changes accepted.doc 50.48(c)(2)(vii), as long as the appropriate regulatory processes (i.e., a license amendment request) are utilized. A process for a 10 CFR 50.48(c)(2)(vii) License Amendment Request has not yet been agreed upon. Potentially relevant existing FAQ numbers:
FAQ 06-0004 includes a process for defining fire protection system s and features required to meet NFPA 805 Chapter 3 criteria.
Response Section:
Proposed resolution of FAQ and the basis for the proposal:
BACKGROUND The rulemaking performed to implement 10 CFR 50.48(c) identified the need to be able to utilize performance-based methods on the fundamental fire protection program elements and design requirements in Chapter 3. To address this need, 10 CFR 50.48(c) incl uded a provision that allows licensees to use performance-based met hods on Chapter 3 attributes, upon receipt of NRC approval.
Prior to transition, under the standard license condition of GL 86-10, licensees are allowed to make certain types of changes without prio r NRC approval as long as the changes do not adversely affect the plant's ability to achieve and maintain safe shutdown in the event of a fire.
PROCESS This FAQ proposes to utilize the NFPA 805 Change Evaluation process as defined in NEI 04-02 (including consideration of Defense-in-Depth and Safety Margins), as the process for determining acceptability for changes to NFPA 805 Chapter 3 requirements that are implemented through referenced codes, standards and listings.
To apply this method, licensees must send the proposed methods outlined in this FAQ (the
Change Evaluation process defined in NEI 04-02) to the NRC for approval. Then, they may use the approved method without prior approval for sp ecific applications, as long as the application is within the bounds of NRC approval of the proposed methods. A pproval of a license amendment for the use of this process would constitute a "previously approved alternative" as discussed in NFPA 805 Section 3.1.
The licensee must request an amendment under 10 CFR 50.90, using the flexibility available under 10 CFR 50.48(c)(2)(vii), "Performance-Based Methods". Once approved, the license amendment would allow licensees to make changes to NFPA 805 Chapter 3 requirements, as long as those changes only affect the referenced codes, standards and listings, such as NFPA, Underwriters Laboratory, Inc. or Factory Mutual listings (Note that refe renced codes, standards FAQ Number 06-0008 FAQ Revision 7 FAQ Title Alternative Method for Fire Protection Engineering Analyses Page 3 of 10 FAQ 06-0008 Engineering Analyses Rev 7 - changes accepted.doc and listings refer to the "code of record" as defined in sec tion 1.8 of NFPA 805. A licensee's code of record may be different than those referenced in NFPA 805). Under the proposal the licensee will commit to a process to evaluate deviations from referenced codes, standards and listings required by NFPA 805 Chapter 3. The NFPA 805 change evaluation process will be used to ensure that nuclear safety performance goals , objectives and criteria are satisfied along with defense-in-depth and safety margins, as described in 10 CFR 50.48(c)(2)(vii).
Therefore, application of this method requires two steps. First, the methods and bounds of the process must be submitted to the NRC for approval. Second, following ap proval by the NRC, all plant specific changes made using the met hod proposed and approved under this license amendment will undergo the same evaluation process as required by 10 CFR 50.48(c)(2)(vii). This second step, application of the method, will not require NRC approval.
This method would not apply to NFPA 805 Chapter 3 changes that do not refer to codes, standards or listings. These types of changes would continue to require individual 10 CFR 50.90 license amendment requests addressing the specific deviation.
Proposed addition to the post-NFPA transition fire protection standard license condition (Section C.3.1 of Regulatory Guide 1.205):
"Licensees may perform change evaluations for deviations from the codes, standards, and listings referenced in NFPA 805, without a 10 CFR 50.90 submittal, as long as the specific requirement for the feature is not included in NFPA 805 Chapter 3, and the NFPA 805 change process is used."
The following provides the sections of NFPA 805 that will utilize this method.
Column Heading Definition:
Fire Protection Engineering Analysis Process Applicable: Sections of NFPA 805 Chapter 3 containing referenced codes and listings. Note the "Applicability" would only apply to the referenced codes, standards, a nd listings contained within thes e sections, and the process could not be used to change the NFPA 805 Chapter 3 specific requirements.
Fire Protection Engineering Analysis Not Applicable:
These NFPA 805 Chapter 3 sections
do not have referenced codes, standards, or listings. Therefore, the method associated with this FAQ is not applicable and would be outside the scope of the associated LAR.

FAQ Number 06-0008 FAQ Revision 7 FAQ Title Alternative Method for Fire Protection Engineering Analyses Page 8 of 10 FAQ 06-0008 Engineering Analyses Rev 7 - changes accepted.doc EXAMPLE Section 3.6.1 of NFPA 805 requires a hose system to be installed per NFPA 14. Using this method, a hose system must be available and have access to "all power block buildings," and must also be a Class III standpipe, but may deviate from other specific requirements of NFPA 14 if the deviation is evaluated and found to be acceptable using this methodology. These deviations must not contradict other text in Chapter 3 of NFPA 805. The NFPA 805 change evaluation process will be used to ensure that nuclear safety performance goals, objectives and criteria are satisfied along with defense-in-depth and safety margins, as described in 10 CFR 50.48(c)(2)(vii).
JUSTIFICATION Since this method will be approved by the NRC as part of the 10 CFR 50.90 submittal, it will meet the legal requirement of 10 CFR 50.48(c)(2)(vii).
The basis for the change evaluation to be included in the 10 CFR 50.90 submittal will be that each individual change will be evaluated against the NFPA 805 change process (NFPA 805 performance goa ls / objectives / criteria, defense-in-depth and safety margins evaluation), and providing this flexibility does not adversely impact the features required by Chapter 3 of NFPA 805 to ensure the NFPA 805 performance goals, performance objectives, and performance criteria are satisfi ed. By only allowing changes to NFPA 805 Chapter 3 referenced codes, standa rds, and listings, the changes are bounded. All features required by Chapter 3 will continue to be required (unless specifically addressed separately from this process in an LAR). NFPA 805 Chapter 3 features addressed by referenced codes, standards and listings may be changed based on an evaluation, using the required methods described in this FAQ (once reviewed and approved by the NRC in the license amendment) in a similar manner as is currently allowed under th e Generic Letter 86-10 li cense condition, without prior NRC approval.
The method will ensure that the following requirements are met:
10 CFR 50.48(c)(2)(vii) Requirement Method of Accomplishment (a) The required NFPA 805 performance goals, performance objectives, and performance criteria are satisfied. The fire protection engineering analysis process includes the assessment of impact on NFPA 805 performance goals, performance objectives, and performance criteria are satisfied. Impact will be assessed per risk-informed, performance-based change process in NEI 04-02 Chapter 5 and Appendices I and J and supplemented by RG 1.205 Section 3.2. (b) Safety margins are maintained.
Maintaining safety margins will be ensured using the risk-informed, performance-based change process in NEI 04-02 Chapter 5 and Appendices I and J and supplemented by RG 1.205 Section C.3.2.

Maintaining fire protection defense-in-depth will be ensured using the risk-informed, performance-based change process in NEI 04-02 Chapter 5 and Appendices I and J and supplemented by RG 1.205 Section C.3.2.
FAQ Number 06-0008 FAQ Revision 7 FAQ Title Alternative Method for Fire Protection Engineering Analyses Page 10 of 10 FAQ 06-0008 Engineering Analyses Rev 7 - changes accepted.doc CLARIFICATION Certain fire protection systems and features have performance requirements that are conditional upon NFPA 805 Chapter 4 requirements. These systems and features are: Fire Alarm and Detection Systems [NFPA 805 Section 3.8] Automatic and Manual Water-Based Fire Suppression Systems [NFPA 805 Section 3.9] Gaseous Fire Suppression Systems [NFPA 805 Section 3.10] Passive Fire Protection Feat ures [NFPA 805 Section 3.11] For these systems and features, the performance requirements are established by the deterministic and/or performance-based analyses used in demonstrating how the NFPA 805 Chapter 4 performance criteria are met. Fire Protection Engineering Analyses may be used to demonstrate how these systems and features m eet the NFPA 805 Chapter 4 criteria (e.g., coverage/performance of a detection / suppression system, ability of fire barriers to withstand expected fire hazards, etc.). These Fire Protection Engineering Analyses, however, are allowed under 10 CFR 50.48(c) and do not require specific permission under 10 CFR 50.48(c)(2)(vii), "Performance-Based Methods".
CONCLUSION This method will permit a risk-informed, performance-based approach to evaluate Fire Protection Program changes to features require d by NFPA 805 Chapter 3 within the bounds of referenced codes, standards, and listings.
Following NRC approval of a 10 CFR 50.90 license amendment, this method will permit licensees to evaluate Chapter 3 fire protection features in referenced codes, standards, and listings wit hout prior NRC approval.
Other NFPA 805 Chapter 3 issues not involving codes, standards, or listings would have to be submitted for NRC approval on a case by case basis.
If appropriate, provide proposed rewording of guidance for inclusion in the next Revision:
[See attached proposed revision to NEI 04-02]
Section 2.2, page 7, 3 rd paragraph: Performance-Based Meth ods, § 50.48(c)(2)(vii) -
The prohibition in Section 3.1 of NFPA 805 that does not permit the use of performance-based methods for the Chapter 3 fundamental fire protection program elements and minimum desi gn criteria is not endorsed. The NRC takes this exception in order to provide licensees greater flexibility in meeting the fire protection program elements and minimum design requirements of Chapter 3 by the use of performance-based methods (including the use of risk-informed methods) described in the NFPA 805 standard. Licensees who wish to deviate from Chapter 3 requirements must submit a license amendment request for NRC approval. Refer to Appendix L for a method to be submitted in the transition LAR to allow fire protection engineering analyses to address NFPA 805 Chapter 3 requirements for deviations from the referenced NFPA codes, standards, and listings referenced in NFPA 805. Approval of a license amendment for the us e of this process would constitute a "previously approved alternativ e" that would allow the use of this process without prior approval for specific applications , as long as the application is within the bounds of NRC approval of the proposed methods/processes.
Section 2.3, page 9, 2 nd paragraph:
"Compliance with Chapter 3 of NFPA 805 may be demonstrated by showing that the specific requirements are met either directly or by the use of alternative me thods and analytical approaches. Alternative methods and analytical approaches must be accepted by the NRC in a license amendment per 10 CFR 50.48(c)(4). Contrary to Section 3.1 of NFPA 805, performance-based methods may be used. (See 10 CFR 50.48(c)(2)(vii)). Note licensees contemplating applying for permission to use an alternative method or analytical approach could pursue a generic approval process with ot her utilities and/or NEI. See Section 2.4 of this document.
Refer to Appendix L for a method to be submitted in the transition LAR to allow fire protection engineering analyses to address NFPA 805 Chapter 3 requirements for deviations from the NFPA codes, standards, and lis tings referenced in NFPA 805.

Section 5.3.2, page 46, starting with 7 th paragraph:
"Additional consideration should be given to changes to Fundamental Program Elements and Minimum Design Requirements. 10 CFR 50.48(c)(2)(vii) allows licensees to use performance-based methods to demonstrate compliance with NFPA 805 Chapter 3 requirements.

Most changes to the Fundamental Program Elements and Minimum Design Requirements should not require a License Amendment request, since they are evaluations that demonstrate compliance with requirements of Chapter 3 of NFPA 805. License es can deviate from the NFPA standards referenced in NFPA 805 Chapter 3 with in the bounds discussed in Appendix L.

FAQ 06-0008 rev. 7 - NEI 04-02 markup - Page 3
Examples of changes that would not require a License Amendment are: Replacing a fire rated component (e.g., penetration seal, door, wrap, etc.) with a different component/material having the same or greater fire rating. This does not require a license amendment because it meet s the appropriate code. Changing the surveillance frequency of a fire protection feature or system based on NFPA standard as long as the underlying basis for the NFPA standard frequency is the same. This does not require a license amendment because the surveillance frequency would satisfy that specified in the curre nt edition of NFPA codes for providing reasonable assurance that the system or component is maintained in an operable condition. Evaluating a blocked sprinkler head(s) for adeq uate coverage in the area. Chapter 3 of NFPA 805 and the referenced code do not dictate where a sprinkler system should be installed. Therefore the adequ acy of the coverage should be evaluated with respect to the nuclear safety component(s) the sprinkler system is protecting. Evaluating a broken/missing hanger on a fire suppression system. The acceptability of
this deviation can be evaluated to show that the support of the system is still adequate with the broken/missing hanger and is therefore equivalent to a code compliant system as allowed by the code of record. Conversely, examples of changes that would require a License Amendment are: Revision of concentration of an agent to a value less than that required by the respective code or previously approved value.
Reducing the number of fire brigade me mbers required on-site to below five. Elimination of the Fire Prevention Program at the plant NFPA 805 Section 4.1, states that, "Deterministic requirements shall be "deemed to satisfy" the performance criteria and require no further e ngineering analysis." Chapter 4 of NFPA 805 provides the requirements for the baseline evaluation of the fire protection program's ability to achieve the performance criteria outlined in Section 1.5 of NFPA 805. The 'deemed to satisfy' with out additional engineering analysis does not imply that a Plant Change Evaluation would not be performed. For example if a licensee wa s changing its current li censing basis in a fire area to a 'deterministic method', that change would require a 'Plant Change Evaluation'. Note the Defense in Depth and Safety Margin portion of the "Plant Change Evaluation' would be satisfied by the fact that a 'deterministic' option was chosen for comp liance (See Sections 2.4.4.2 and 2.4.4.3 of NFPA 805)." ------------------------------------

Appendix L - Alternative Method for Engineering Analyses PLACEHOLDER FOR A DESCRIPTION OF NRC POSITION ON THIS FAQ.
L.1 Background 10 CFR 50.48(c) requires licensees to submit 10 CFR 50.90 license amendment requests for any changes to Chapter 3 features of NFPA 805, unle ss they have been previously approved by the NRC. Under the standard licen se condition of GL 86-10, licensees are allowed to make certain types of changes withou t prior NRC approval as long as the changes do not adversely affect the plant's ability to safely shutdown in the event of a fire.
To apply this method, licensees must send the proposed methods outlined in this Appendix to the NRC for approval. Then, they may use the approved processes/methods without prior approval for specific applications, as long as the application is within the bounds of NRC approval of the proposed methods/processes. Approval of a license amendment for the use of this process would constitute a "previously approved alternative" as discussed in NFPA 805 Section 3.1.
The licensees' methodology must request an amendment under 10 CFR 50.90, using the flexibility available under 10 CFR 50.48(c)(2)(vii), "Performance-Based Methods", to allow 10 CFR 50.48(c) licensees to establish a process that enables them to make cha nges to Chapter 3 of NFPA 805, as long as those change s only affect the referenced st andards and listings, such as Underwriters Laboratory, Inc. or Factory Mutual listings. Under the proposal the licensee will commit to a process to evaluate deviations from referenced codes, standards, and listings required by NFPA 805 Chapter 3. The NFPA 805 ch ange evaluation process will be used to ensure that nuclear safety performance goals, objectives and criteria are satisfied along with defense-in-depth and safety margins, as described in 10 CFR 50.48(c)(2)(vii).
Therefore, application of this method requires two steps. First, the methods and bounds of the process must be submitted to the NRC for approval. Second, following approval by the NRC, all plant specific changes made under this license amendment will undergo the same evaluation process required by 10 CFR 50.48(c)(2)(vii). This second step, application of the method, will not require NRC approval.
This method would not apply to NFPA 805 Chapter 3 changes that do not relate to referenced codes, standards, or listings. These types of changes would continue to require individual 10 CFR 50.90 license amendment requests a ddressing the specific deviation.
L.2 Process Proposed addition to the post-NFPA transition fire protection standard license condition (Section C.3.1 of Regulatory Guide 1.205:
"Licensees may perform change evaluations for deviations from the codes, standards, and listings referenced in NFPA 805, without a 10 CFR 50.90 submittal, as long as the specific requirement for the feature is not in cluded in NFPA 805 Chapter 3 and the NFPA 805 change process is used."

Appendix L - Alternative Method for Engineering Analyses L.3 Example Section 3.6.1 of NFPA 805 requires a hose system to be installed per NFPA 14. Using this method, a hose system must be available and have access to "all power block buildings," and must also be a Class III standpipe, but may deviate from other specific requirements of NFPA
- 14. These deviations must not contradict othe r text in Chapter 3 of NFPA 805. The NFPA 805 change evaluation process will be used to ensure that nuclear safety performance goals, objectives and criteria are satisf ied along with defense-in-depth and safety margins, as described in 10 CFR 50.48(c)(2)(vii).
L.4 Justification Since this method will be approved by the NRC as part of the 10 CFR 50.90 submittal, it will meet the legal requirement of 10 CFR 50.48(c)(2)(vii).
The basis for the change evaluation to be included in the 10 CFR 50.90 submittal will be that each individual change will be evaluated against the NFPA 805 change process (NFPA 805 performance goa ls / objectives /criteria, defense-in-depth and safety margins evaluation), and providing this flexibility does not adversely impact the features required by Chapter 3 of NFPA 805 to ensure the NFPA 805 performance goals, performance objectives, and performance criteria are satisfi ed. By only allowing changes to the referenced codes, sta ndards, and listings, the changes are bounded. All features required by Chapter 3 will continue to be required (unless specifically addressed separately from this process in an LAR). Secondary features ma y be changed based on an evaluation, using the required methods in a similar manner that was previously allowed under the Generic Letter 86-10 license condition, wit hout prior NRC approval.
The method will ensure that the following requirements are met:
10 CFR 50.48(c)(2)(vii) Requirement Method of Accomplishment (a) The required NFPA 805 performance goals, performance objectives, and performance criteria are satisfied.
The fire protection engineering analysis process includes the assessment of impact on NFPA 805 performance goals, performance objectives, and performance criteria are satisfied. Impact will be assessed per risk-informed, performance-based change process in NEI 04-02 Chapter 5 and Appendices I and J and supplemented by RG 1.205 Section 3.2.
(b) Safety margins are maintained.
Maintaining safety margins will be ensured using the risk-informed, performance-based change process in NEI 04-02 Chapter 5 and Appendices I and J and supplemented by RG 1.205 Section C.3.2.
(c) Fire protection defense-in-depth is maintained.
Maintaining fire protection defense-in-depth will be ensured using the risk-informed, performance-based change process in NEI 04-02 Chapter 5 and Appendices I and J and supplemented by RG 1.205 Section C.3.2.

Appendix L - Alternative Method for Engineering Analyses L.5 Clarification Certain fire protection systems and features have performance requirements that are conditional upon NFPA 805 Chapter 4 requirements. These systems and features are:
Fire Alarm and Detection Systems [NFPA 805 Section 3.8]
Automatic and Manual Water-Based Fire Suppression Systems [NFPA 805 Section 3.9]
Gaseous Fire Suppression Systems [NFPA 805 Section 3.10]
Passive Fire Protection F eatures [NFPA 805 Section 3.11]
For these systems and features, the performance requirements are established by the deterministic and/or performance-based analyses used in demonstrating how the NFPA 805 Chapter 4 performance criteria are met. Fire Protection Engineering Analyses may be used to demonstrate how these systems and features m eet the NFPA 805 Chapter 4 criteria (e.g., coverage/performance of a detection / suppression system, ability of fire barriers to withstand expected fire hazards, etc.). These Fire Protection Engineering Analyses, however, are allowed under 10 CFR 50.48(c) and do not require specific permission under 10 CFR 50.48(c)(2)(vii), "Performance-Based Methods".

Appendix L - Alternative Method for Engineering Analyses L.6 Conclusion This method will permit a risk-informed, performance-based approach to evaluate Fire Protection Program changes to NFPA 805 Chapter 3 requirements within the bounds of referenced codes, standards, and listings.
Following NRC approval of a 10 CFR 50.90 license amendment, this methodology will permit licensees to evaluate fire protection features without prior NRC approval. Other NFPA 805 Chapter 3 issues, not involving codes, standards, or listings, would have to be submitted for NRC approval on a case by case basis.
