7 Fire Modeling and Emergency System Response Performance-Based Analysis There is a movement toward risk-informed, performance-based analyses in the field of fire protection engineering, both domestically and worldwide. In response to this movement, the U.S. Nuclear Regulatory Commission (NRC) has amended its fire protection requirements in Regulatory Guidance to permit existing reactor licensees to voluntarily use risk-informed, performance-based fire protection methods to supplement existing deterministic fire protection requirements. Fire Modeling AREVA utilizes Fire Dynamics Simulator (FDS), a Computational Fluid Dynamics (CFD) model of fire-driven fluid flow, developed by the National Institute of Standards and Technology (NIST) Fire modeling is the fundamental tool for evaluation of acceptance criteria in risk-informed, performancebased fire protection. Using fire modeling, it is possible to virtually assess the extent of damage, to impose design criteria, and to evaluate the effectiveness of emergency systems. AREVA engineers have the expertise and experience to perform detailed fire modeling computations consistent with the requirements of the NRC and National Fire Protection Association (NFPA). Our team is focused on delivering application-specific solutions to meet your performance objectives. The Big Picture To effectively utilize the results of fire modeling, it is important to understand the overall fire safety envelope. We have effectively used fire modeling output in Fire Probabilistic Risk Assessment (PRA) and to sustain/support code variances, alternative positions, risk-informed performance-based approaches, regulatory exemptions, and other legal positions. AREVA fire protection engineers are missionoriented, not task-oriented. We keep your needs in mind throughout every phase of the project. Our knowledge of the limitations and ranges of application of all fire modeling software approved for use in nuclear power plants allows us to select the most cost-effective methods to meet your project goals. AREVA engineers know how to interpret the results of fire modeling, and we know how to clearly convey those results to our clients. Features and Benefits Cost reduction benefits can be provided in applying fire modeling techniques as follows: Provides clients with alternatives to prescriptive regulatory requirements Produces system designs tailored to meet your specific performance objectives Features of the fire modeling application include: Uses state-of-the-art computational fire and egress modeling software Calculations performed by engineers with industryrecognized expertise Computational methods based on NFPA requirements using NRC-approved calculation procedures

8 Tools, Techniques & Applications In applying fire modeling to performance-based analysis, AREVA retains experienced engineers with degrees in fire protection to construct the necessary scenarios for evaluation. Fire modeling requires skillful application to ensure that the input data is appropriate for the conditions being analyzed. Following are some potential fire modeling applications. Fire Suppression Systems AREVA engineers can model the effects of a wide range of fire scenarios to determine the necessity and suitability of fire suppression systems such as wet, dry, pre-action and deluge sprinkler systems, fixed water spray, water mist, and gaseous fire suppression systems. We can also utilize fire modeling to gain insight on various fire suppression system designs and their associated performance. Fire Detection and Alarm AREVA engineers can model detection devices within a compartment, establishing a sequence of events. Detector types supported by available fire models include heat detection, ionization, photoelectric, beam type and air-sampling incipient stage type smoke detection. We can also represent fire alarm system signal reporting logic as required for modeling suppression or smoke control system activation, closing fire and smoke dampers, and initiating other alarm sequences. AREVA employs sophisticated egress models that can track the movement of individual site personnel and create a three-dimensional video animation of building evacuation. Smoke Control Systems Our team has the technical expertise to correctly model smoke control systems including smoke exhaust, post-event smoke purging systems, smoke and heat vents, opposed airflow systems, elevator, stairwell and corridor pressurization systems. Tenability & Timed Egress Analysis AREVA engineers can establish emergency system design criteria to maintain tenability in occupied spaces such as the MCR, and can also use timed egress analysis to demonstrate the effectiveness of emergency systems during evacuation. Timed egress analysis is applicable for zoned evacuation, building evacuation, and site-wide evacuation. Building & Target Survivability AREVA engineers can produce a real-time analysis of target performance criteria. We can evaluate survivability of mechanical, electrical, instrumentation and control systems, analyze thermal impact to building structural elements, and evaluate extent of damage for post-incident recovery.

9 Nuclear Plant Transition to NFPA 805 AREVA, the world s leading nuclear supplier, is recognized throughout the industry as a premier provider of fire protection engineering, design and analysis services. Background The Nuclear Regulatory Commission endorsed National Fire Protection Association (NFPA) Standard 805, Performance-Based Standard for Fire Protection for Light Water Reactor Electric Generating Plants, as an acceptable voluntary approach for demonstrating compliance with 10 CFR 50.48, Fire Protection. This endorsement allows plants to move away from prescriptive fire protection requirements and realize the benefits of using risk-informed, performancebased methods to analyze the consequences of fires and their impact on the ability to achieve and maintain safe shutdown. Involved and Engaged AREVA has actively supported the development of NFPA 805 and is a leader in fire protection standards development, industry working groups, and industry forum presentations. Additionally, as part of a Nuclear Energy Institute (NEI) initiative, members of our team helped develop the advanced performance-based methods for circuit analysis described in NEI 00-01, Guidance for Post-Fire Safe Shutdown Circuit Analysis. We were also selected by NEI to support pilot plant evaluations of this methodology to demonstrate compliance with regulatory requirements. Considering the Transition to NFPA 805 Adopting NFPA 805 is a significant undertaking. Potential benefits must be thoroughly evaluated against costs each step of the way. Our team of professionals can help determine if transforming your licensing basis to NFPA 805 makes sense for your plant. We do this by evaluating the following attributes of your compliance approach: Maximizing the use of your current licensing basis and documentation Minimizing the need to reconstitute the current design and licensing bases Identifying potential program vulnerabilities and formulating the specific cost-effective changes needed for NFPA 805 compliance Assessing short-term and long-term costs versus benefits Features and Benefits Cost savings in addressing future FP issues Reduced reliance on manual operator actions Reduced reliance on fire barriers Eliminate deviations and exemption requests More realistic analysis of plant fire scenarios Reduced surveillance frequencies Enhanced license renewal support by meeting contemporary regulatory expectations

10 A Complete Solution We offer full scope, turn-key engineering services for all three phases of the NFPA 805 transition process: Preliminary assessment and letter of intent Analysis and License Amendment Request (LAR) Completion of transition including revising your PRA, fire hazards analysis and safe shutdown analysis The NFPA 805 transition assessment process is depicted in the following simplified flow chart (taken from the NEI 04-02):

11 Transitioning to NFPA 805 The transition to NFPA 805 requires performing several evaluations and analyses: Fire Protection (FP) Fundamentals Assessment Chapter 3 of NFPA 805 requires that licensees assess their current compliance status. Prior approved alternates to the existing FP program may take precedence over NFPA 805 criteria so it is vital that the plant licensing basis be well understood. The NRC may accept these changes, but will undoubtedly review them again in the context of the change to a performance-based approach. Nuclear Safety Analyses Most NFPA 805 nuclear safety performance goals are comparable to existing regulatory requirements (10 CFR 50 Appendix R III.G and III.L). The nuclear safety analysis includes a systematic review of the following existing program elements: Nuclear safety system and equipment selection Nuclear safety capability circuit analysis Nuclear safety equipment and cable location Fire area assessments Manual Action Feasibility Breaker Coordination /common enclosure Those plants with well-documented safe shutdown methodologies will be able to integrate much of their current analysis for risk significant areas. However, NFPA 805 also requires the assessment of fires originating during non-power operational modes and fires that result in radioactive release that were not previously part of most FP programs. Non-Power Operational Mode Assessment This assessment requires an evaluation of different components and time-sequences from the normal safe shutdown paths (primarily assessing decay heat removal capability) as well as an evaluation of key safety functions needed for high risk evolutions during non-power modes (see NUMARC 91-06). Radioactive Release Assessment Licensees are also required to show that FP goals are also met with respect to limiting radioactive releases with the objective of showing no releases due to loss of boundary controls (other than those already evaluated as primary nuclear safety boundaries). NFPA 805 Transition Software (DATATRAK) The NFPA 805 Transition Data Tracking System (DATATRAK) has been developed by AREVA as a tool for modeling, managing and reporting data related to performing an NFPA 805 Transition analysis. The application has been designed to integrate the data elements and relationships required to support the various tasks related to performing both Fire Safe Shutdown and NFPA 805 Transition Analyses. Data screens and reports have been designed to accommodate the data input and reporting requirements for NFPA 805 Transition tasks such as the following: Safe Shutdown System and Component Selection Modeling Interlock, Power and Sub-component Dependencies Cable Selection for SSD, PRA and NPO Cable Routing and Location Fire Area SSD Assessments Non-Power Operation Assessments Basic Event Mapping to Cables Fire PRA Impact Assessments Fire PRA Scenario Zone of Influence Calculations Determing impact to analyses due to data revisions Generate LAR Tables This analysis involves modeling information associated with components, cables and raceways to determine the impact of fire damage on the ability to achieve safe shutdown within each fire zone or fire area. The DATATRAK application supports both the Nuclear Safety Analysis plus the additional NFPA 805 related tasks such as Non-Power Operational Mode assessments and calculating Fire PRA cable impacts including Basic Event mapping and Fire Scenario cable impacts. The database system is also designed to link to external data sources such as selected plant cable raceway data tables and selected PRA CAFTA Basic Event data tables in support of the analysis. In addition, the software is also designed to identify the delta resulting from revisions to these external data sources used as design input to the Transition Analysis in order to maintain data configuration control. This software solution has been developed from AREVA s expertise in supporting various NFPA 805 transition projects and has received favorable reviews from the NRC during Pilot Plant reviews. Furthermore, the design of the application supports customization to meet the needs of each plantspecific project by integrating all the elements required to support this analysis.

12 Probabilistic Risk Analysis (PRA) Fire PRA is dependent on the application of event tree/fault tree analysis, which is a core competency of AREVA fire PRA personnel. Our detailed knowledge of plant accident sequences, design and operation helps customers understand the overall risk to their plant especially from postulated fire-induced component failures, system interactions, and dependencies. AREVA has supported the latest methods for fire PRA for full power operations as contained in EPRI/NRC-RES Fire PRA Methodology for Nuclear Power Facilities, NUREG/CR This methodology enhances cable selection and circuit analysis, and uncertainty analysis. Significant changes include development of ignition frequencies, post-fire HRA and fire modeling. Plus, the methodology improves component selection, development of the fire-induced risk model, and quantitative screening. Fire Modeling As an integral component of NFPA 805, fire modeling is used to determine the survivability of plant structures, systems and components as well as predict tenability within the fire areas of concern. However, for fire modeling to be effective, each program must be applied with a clear understanding of its limitations. Fire scenario construction must be fully cognizant of the following attributes: Proper characterization of fire source term Target pass/fail criteria Plume and ceiling jet/layer development and orientation Direct flame radiation exposure Ignition criteria for proximate/contributory combustibles AREVA Inc IBM Drive, Charlotte, NC Joel Drennan Business Development Manager 4100 International Plaza, Suite 750 Fort Worth, Texas Joel.Drennan@areva.com Tel: Cell: or contact: AREVA Engineering Control Center EngineeringControlCenter@areva.com Tel: us.areva.com AREVA has the expertise and experience to construct the proper scenarios and apply the right fire modeling tools to yield technically sound results. Program Change and Licensing Basis Other aspects of the transition to the risk-informed, performance-based approach of NFPA 805 is evaluating the convertability of the program itself. The adequacy of existing configuration control, quality assurance, program surveillance and monitoring, administrative control attributes, and corrective action processes are all items that must be considered and appropriately integrated/ updated as needed. This process ensures that the new licensing basis for fire protection is correctly oriented to accommodate and manage future change and will stand up to regulatory scrutiny for the life of the plant. Experience You Can Count On AREVA offers the complete range of engineering services needed to help you navigate a successful transition to NFPA 805. Working in concert with your fire protection personnel, we will help map the transition process, develop the cost-benefit analyses needed to support key decisions, and perform the required engineering analyses, licensing submittals and supporting documentation.

15 Nuclear Plant Breaker Coordination Services for NFPA 805 Is Your Plant Ready for NFPA 805 LAR Submittal? Existing breaker coordination calculations that were prepared for Fire Protection Safe Shutdown may not be adequate for transition to NFPA 805. Risk- Informed Performance-Based analyses require a more finite approach to cable analysis and subsequent breaker coordination. These finite scenarios may separate what was once one Fire Area into multiple Fire PRA fire scenarios based on ignition sources. Credit Power Supply Fire PRA Scenario Boundary Exposure Fire Non-PRA Component A Long History of Success AREVA has a proven track record and long history of resolving generic industry fire protection issues and plant-specific concerns. We consistently provide cost-effective analytical techniques and compliance methods to help our clients meet regulatory requirements and plant-performance goals. Comprehensive Services Our multi-disciplined staff provides comprehensive services to address a broad spectrum of issues and concerns. We garner repeat business from numerous clients by consistently demonstrating our ability to resolve industry issues and plant-specific concerns and optimize performance of their Fire Safe Shutdown Programs. Credited PRA Component Fire Area Boundary (Typical) In addition, there is a potential to include more station equipment into a Fire PRA than previous Fire Safe Shutdown Analysis, including non-safety related components. This more finite area analysis along with a potential increase in required power supplies demonstrates the need to re-evaluate the plants breaker coordination for transition to NFPA 805. What Is Required? NFPA 805, Section , requires the inclusion of those circuits that could cause a loss of a power supply required to achieve the nuclear safety performance criteria. This loss could be due to protection devices (i.e. breaker or fuse) that are not properly coordinated with its upstream protection devices. ASME Standard for Probabilistic Risk Assessment for Nuclear Power Plant Applications (ASME-RA-S-2002) requires the confirmation of satisfactory electrical coordination for Fire PRA power supplies. This requirement is part of the Fire PRA Peer Review performed to determine the quality of the PRA. Features and Benefits Our DATATRAK software fully integrates all aspects for Fire Safe Shutdown Analysis into a single design tool including breaker coordination Fire safe shutdown logic diagrams Component circuit analysis Separation analysis and compliance assessments Safe shutdown analysis software (DATATRAK)

18 Modifications Impact Screening Reviews on the NFPA 805 Program The review of plant modification packages include performing a screening review to ensure the modifications do not make changes in the plant that can negatively affect the NFPA 805 Fire Protection Program. Some of the initial review steps include: The review of new, existing and emergent modification packages. Review of elementary drawings and flow diagrams for impacts. Review of critical analyses / evaluations including: a. Fire Probabilistic Risk Assessment b. Nuclear Safety Capability Assessment for At Power c. Nuclear Safety Capability Assessment for Non-power Operations d. Classical Fire Protection e. Breaker Coordination f. Code Compliance Typically, the NFPA 805 modification reviews will require the identification and development of the necessary work processes and procedures for maintaining configuration control. This effort will be key for maintaining configuration control of the program for the ongoing life of the plant. AREVA has developed these processes / procedures for other plant sites and can use the lessons learned from these projects to streamline the process for your plant.

19 Nuclear Plant Fire PRA Program Implementation AREVA, the world s leading nuclear supplier, is recognized throughout the industry as a premier provider of fire protection engineering, design and analysis services. Industry Issue For utilities that have decided to retain their 10CFR 50, Appendix R licensing basis, NRC Regulatory Guide has provided a path to use specific performance-based tools to evaluate and mitigate risks within the plant. Based on the NRC guidance, Fire Probabilistic Risk Assessment (Fire PRA) methodology can be used to mitigate circuit issues, such as Multiple Spurious Operations (MSOs). AREVA Solution AREVA is currently supporting our clients with the development of a new Fire PRA program with a proven track record. In addition, AREVA has supported clients in addressing the impacts of fire induced circuit MSOs, analyzing impacts on circuit routings, and updating component / cable selection data. Involved and Engaged AREVA has actively supported the development of fire protection NFPA standards, industry working groups, and industry forum presentations. Additionally, as part of a Nuclear Energy Institute (NEI) initiative, members of our team helped develop the advanced performance-based methods for circuit analysis described in NEI 00-01, Guidance for Post- Fire Safe Shutdown Circuit Analysis. We were also selected by NEI to support pilot plant evaluations with the application of this methodology to demonstrate compliance with regulatory requirements. Considering Developing a Fire PRA Program Utilities often determine the implementation of risk-informed Fire PRA methodology is the most beneficial methodology by evaluating the risk impacts of fire induced circuit MSOs versus the potential for rerouting circuits or relocating components. AREVA has the knowledge and experience to supplement the plant engineering staff with fire protection (FPE) and safe shutdown (SSE) engineers for developing and implementing a Fire PRA program as allowed by Regulatory Guide 1.189, while maintaining the current plant licensing basis. This effort typically includes having AREVA project team resources available to support initiation of revised and new procedures, and training of modification engineers for impacts on the program. AREVA can provide the following services in developing a Fire PRA program: Review of impacted cables and components for updated routing location information or for missing cable routes / endpoints Develop component failure tag cable mapping data Perform the modeling and reports for identifying MSO risks Provide mentoring services for the plant engineering staff for maintaining the Fire PRA Program Update DATATRAK software to interface with the plant cable and raceway database to maintain configuration control Features and Benefits Cost and man-hour savings for future modifications in identifying MSO risks Mentoring program for the plant engineering staff

20 Fire PRA Supporting Software (DATATRAK) The Fire PRA supporting Data Tracking System (DATATRAK) software has been developed by AREVA as a tool for modeling, managing and reporting data related to a Fire PRA program. The application has been designed to integrate the data elements and relationships required to support Fire Safe Shutdown Analyses and Fire PRA related tasks. Data screens and reports have been designed to accommodate the data input and reporting requirements for Fire PRA tasks such as the following: The System and Component Selection Modeling Interlock, Power and Sub-component Dependencies Cable Selection for Safe Shutdown, Probabilistic Risk Assessment and Non-Power Operations Cable Routing and Location Basic Event Mapping Fire PRA Impact Assessments Fire PRA Scenario Zone of Influence Calculations Evaluation / Analysis of Impact Due to Data Revisions The use of DATATRAK involves modeling information associated with components, cables and raceways to determine the impact of fire damage on Core Damage Frequency (CDF) risks within each fire zone or fire area. The software also includes Basic Event mapping and Fire Scenario cable impacts. The database system is also designed to link to external data sources such as selected plant cable raceway data tables and selected PRA Computer Aided Fault Tree Analysis CAFTA Basic Event data tables in support of the analysis. In addition, the software is also designed to identify the delta resulting from revisions to these external data sources used as design input in order to maintain data configuration control. This software solution has been developed from AREVA s expertise in supporting various NFPA 805 transition projects and has received favorable reviews from the NRC during Pilot Plant reviews. Furthermore, the design of the application supports customization to meet the needs of each plant-specific project by integrating all the elements required to support this analysis. Mentoring of Plant Engineering Resources AREVA understands that the plant engineering staff must ultimately implement the Fire PRA Program; therefore, we provide mentoring of the program so this responsibility can be transferred to the plant staff as quickly as possible. This transition typically is accomplished with the simultaneous mentoring and training of the plant staff in the process and tools used during the screening. To accomplish this, AREVA will provide our engineering personnel on site to work with the plant engineering for implementing the process of performing screenings and documentation updates.
