FOREWORD
In 1974, the IAEA established a special Nuclear Safety Standards (NUSS) programme under which a number of Codes and Safety Guides have been produced in the areas of governmental organization, siting, design, operation and quality assurance. The NUSS Codes and Guides are a collection of basic and derived requirements for the safety of nuclear power plants with thermal neutron reactors. They have been developed in a complex process which ensures the best possible international consensus.
In order to present further details on the application and interpretation and on the limitations of individual concepts in the NUSS Codes and Safety Guides, a series of Safety Practice publications have been initiated. It is hoped that many Member States will benefit from the experience presented in these books.
The present publication has been developed with the help of experts from regulatory, operating and engineering organizations, all with practical experience in the field of fire protection of nuclear power plants. The publication outlines practices for inspecting the fire protection measures at nuclear power plants in accordance with Safety Series No. 50-SG-D2 (Rev. 1), Fire Protection in Nuclear Power Plants, and includes a comprehensive fire safety inspection checklist of the specific elements to be addressed when evaluating the adequacy and effectiveness of the fire protection measures and manual fire fighting capability available at operating nuclear power plants. The publication will be useful not only to regulators and safety assessors but also to operators and designers.
The book addresses a specialized topic and it is recommended that it be used in conjunction with Safety Guide No. 50-SG-D2 (Rev. 1).
The IAEA is grateful to all the experts who helped in the drafting and reviewing of this publication.

1. INTRODUCTION
1.1. BACKGROUND
Safety Series No. 50-SG-D2 (Rev. 1), Fire Protection in Nuclear Power Plants, was developed as part of the IAEA Nuclear Safety Standards (NUSS) programme. The Guide established the specific concepts of fire protection related to the design, layout and construction of nuclear power plants. The Guide discussed, inter alia, the recommended concepts for designing the fire detection and fire extinguishing systems and for protecting the plant, as well as the associated main requirements for manual fire fighting.
It is recognized that effective fire protection includes a number of distinct elements that must be integrated into a comprehensive fire safety policy. As a minimum, these elements cover organization; a fire prevention programme, including the administrative control procedures; a comprehensive fire hazard analysis; provision for passive fire protection measures; installation of reliable and effective fire detection and extinguishing systems and equipment (including a degree of redundancy, where necessary, to cover the single failure criterion as defined in para. 531 of Safety Series No. 50-SG-D2 (Rev. 1)); periodic inspection, maintenance and testing of all the fire protection measures (both passive and active) provided; a quality assurance programme; and the manual fire fighting capability. To determine the adequacy of the fire protection essential for safety at a nuclear power plant, all these elements must be assessed.
Although comprehensive evaluation of the overall fire safety arrangements requires a thorough review of all the elements listed above, there is value in applying selected elements separately for specific situations. This Safety Practice supplements Safety Guide 50-SG-D2 (Rev. 1) by providing a detailed fire safety inspection checklist to determine whether the requirements for the fire protection measures and fire fighting capability (including manual fire fighting) have been fulfilled in an operating nuclear power plant. The Guide should be used as a primary reference in the application of this Safety Practice.
1.2. OBJECTIVE
The purpose o f this publication is to outline the practices for inspecting the fire protection measures at nuclear power plants in accordance with Safety Series No. 50-SG-D2 (Rev. 1), and includes a comprehensive checklist of the specific elements to be addressed when evaluating the adequacy and effectiveness of the fire protection measures and manual fire fighting capability provided at operating nuclear power plants. The document will be useful not only to regulators and safety assessors but also to operators and designers.

1.3. SCOPE
This Safety Practice provides a methodology and the basis for inspecting the fire protection measures and manual fire fighting capability at nuclear power plants, and for assessing their adequacy. The fire safety inspection checklist reflects the current international practices for inspecting fire safety and provides an objective structure for assessing three elements of fire protection at nuclear power plants: the passive fire protection measures; the design and installation of fire detection and fixed fire extinguishing systems and equipment; and the manual fire fighting capability. This assessment will determine whether the fire protection measures and manual fire fighting capability provided at the plant are in accordance with internationally acceptable practices.
1.4. STRUCTURE
Section 2 describes the methodology to be followed when applying the checklist, including discussion on the specific written documents to be reviewed, the purpose and value of personal interviews with plant personnel, and the necessity of direct visual observation of plant conditions, with a walkdown inspection of the plant.
Section 3 discusses the basis for evaluating each aspect of plant fire protection as ‘satisfactory’, ‘needs further evaluation’ or ‘unsatisfactory’, and describes the important issues to be considered when making recommendations for their improvement.
Section 4 provides a detailed fire safety inspection checklist for determining the adequacy of the fire protection measures and manual fire fighting capability provided at the plant.
2. METHODOLOGY
It is intended that inspection of the techniques used for fire protection and fire fighting be performed by a small group of professional fire safety specialists with experience directly applicable to fire protection in nuclear power plants. The combined experience of the team of technical specialists should include expertise in fire protection system design, knowledge of the fire protection codes and standards, knowledge of the manual fire fighting techniques and experience in fire protection engineering. Judgements of performance are based on the expertise of the individual technical specialists. Therefore, this inspection is not intended to be a formal audit against a single set of codes and standards, but rather a technical exchange of
2

experience and practices at the working level with the aim of improving the reliability and effectiveness of the measures and capability currently provided by the nuclear power plant.
The key objectives of the fire safety inspection are:
(1) To provide the plant with an independent assessment of the effectiveness of the fire protection measures and manual fire fighting capability;
(2) To provide plant management with specific recommendations and suggestions for improvement in areas where performance falls short of internationally acceptable practices;
(3) To provide key personnel at the plant with the opportunity of discussing their experience and practices in fire protection with technical experts who have significant experience in this field.
To be most effective when evaluating the overall fire safety arrangements provided at the plant, the assessment should cover all areas of the site, including the nuclear island and the balance of plant facilities, e.g. the turbine building. However, the primary concern of this publication is the adequacy of the fire protection measures and manual fire fighting capability with respect to the plant systems, equipment and components that are essential for achieving and maintaining safe shutdown of the plant. For the purpose of this Safety Practice, safe shutdown of the plant covers removal of residual heat following initial shutdown and prevention of the release of radioactive materials, as defined in para. 306 of Safety Series No. 50-C-D (Rev. 1), and in para. 202 of Safety Series No. 50-SG-D2 (Rev. 1).
Three primary methods are used to acquire the information needed to assess the effectiveness of the fire protection measures and manual fire fighting capability provided at the plant, and to make specific recommendations for their improvement: a review of written material; interviews with plant personnel; and direct visual observation of the measures and capability.
The fire safety specialists address topics in sufficient detail and to the extent necessary to enable them to make an informed judgement of each item in the checklist. The weaknesses identified are addressed to the degree required to document the specialists’ concerns with sufficient detail and accuracy to make their concerns clearly understandable, and then recommendations are made for addressing these weaknesses. Similarly, the good practices observed during the inspection process are documented for the benefit of other nuclear power plants, and are described in the specialists’ notes in sufficient detail to be readily understood.
2.1. DOCUMENT REVIEW
The specific documents to be reviewed by the technical specialists vary, depending on their availability and on the circumstances at each nuclear power plant.
3
This publication is no longer valid Please see http://www-ns.iaea.org/standards/
It is generally agreed that the documents listed below are important elements of overall plant fire safety. However, the absence of one or more of these review documents should not preclude use of the checklist as an effective tool for assessing the adequacy of the fire protection measures and manual fire fighting capability installed at the plant. The documents to be reviewed include: the fire protection regulatory requirements; the comprehensive fire hazard analysis; the safety evaluation report for fire protection; the fire protection administrative control procedures; the surveillance, maintenance and test procedures for the fire protection systems and equipment; the fire protection system and equipment details and drawings; the fire event records and investigative reports; the training records of on-site and off-site personnel, as applicable; the plant arrangement drawings, including identification of the fire compartment boundaries (as constructed, covering modifications); and the fire emergency plan, including co-ordination with off-site services.
2.2. PERSONNEL INTERVIEWS
Interviews with plant personnel are carried out at all levels with a view to:
(1) Providing additional information not addressed by the documentation;(2) Answering questions and satisfying concerns arising out of the review
documents;(3) Forming a judgement of the plant personnel’s understanding of the fire protec
tion equipment and measures provided, and of their own duties and responsibilities for fire protection;
(4) Forming a judgement of the plant personnel’s competence and professionalism regarding fire protection.
Interviews also provide an opportunity for an exchange of information between technical specialists and plant personnel. These interviews should be seen as part of a constructive dialogue with plant personnel and not as an interrogation. Properly conducted, such interviews play an important role in the inspection process.
2.3. DIRECT OBSERVATION
Site inspection of actual plant conditions is a significant part of the review process. Most of the time allocated to the inspection process should be used to review the fire protection measures and the actual fire fighting capability provided at the plant. Observation of existing conditions includes:
(1) A walkdown inspection of all the relevant plant areas, with emphasis placed on those areas that are important to safe shutdown of the plant, and on any adjacent areas which may form a potential fire hazard to those safety important areas;
4

(2) The combustible fire load and the general housekeeping conditions;(3) The control of ignition sources;(4) The adequacy and integrity of the passive fire protection measures (fire rated
barriers, fire doors, fire dampers, fire barrier penetration seals);(5) The design and installation of the fire detection and fire extinguishing systems
and equipment;(6) The maintenance of the active and passive fire protection measures, based on
visual evaluation;(7) The manual fire fighting capability, including witnessing an unannounced fire
drill at the plant.
On the basis of the results obtained from the review documents, personnel interviews and direct observations, the technical specialists form a judgement of the adequacy of the measures and capability provided at the plant, and then make recommendations for correcting those deficiencies that were identified during the inspection. The important areas cover:
(a) The technical knowledge and skills of the manager and staff responsible for the overall fire safety of the plant;
(b) The adequacy of the passive fire protection measures provided;(c) The effectiveness of the fire protection systems and equipment installed at the
plant, to provide the level of protection required (both system design and operability);
(d) The availability and effectiveness of the manual fire fighting personnel (both on-site and off-site).
3. EVALUATION AND CONCLUSIONS
The fire safety inspection checklist provides a means of evaluating the fire protection measures and manual fire fighting capability in place at the nuclear power plant. It is recognized that effective fire protection must include additional elements such as a comprehensive fire hazard analysis; a fire prevention programme, including the administrative control procedures; periodic inspection, maintenance and testing of the systems and equipment; and a quality assurance programme. These elements are to be addressed specifically in two separate documents currently in preparation at the IAEA: Evaluation of Fire Hazard Analysis for Nuclear Power Plants, and Assessment of the Implementation and Effectiveness of the Overall Fire Safety Arrangements of Nuclear Power Plants.

The checklist for inspecting the fire protection measures and manual fire fighting capability is divided into eight sections:
A. Fire confinement (passive fire protection measures);B. Fire detection and alarm systems;C. Fixed fire extinguishing systems — General;D. Water based fire extinguishing systems;E. Gaseous fire extinguishing systems;F. Foam and dry powder fire extinguishing systems;G. Fire water supply;H. Manual fire fighting capability.
Regarding the safe shutdown requirements (as defined in para. 202 of Safety Series No. 50-SG-D2 (Rev. 1)), each aspect of plant fire protection and the corresponding protection measures, as identified in the checklist, are evaluated. This evaluation leads to one of three conclusions:
(1) Satisfactory, which means that the particular fire protection measure isprovided in accordance with internationally acceptable practices. No enhancements are required. When a particular item is determined to be satisfactory, generally no record of specific comments is required. However, in certain cases it may be desirable to record specific details that form the basis for such a determination. It is also important to identify good practices that may be beneficial to other nuclear power plants.
(2) Needs further evaluation, which means either that the particular fire protection measure does not meet the requirements, or that further details will have to be provided before a definite judgement is made. In both cases, a specific recommendation is made on how to resolve the issue.
(3) Unsatisfactory, which means that the particular fire protection measure is notprovided in accordance with internationally acceptable practices. This couldarise from the use of inadequate material, systems or equipment; the inadequate fire resistance of specific components; an inappropriate design approach, etc. Each statement is accompanied by an explanation of the technical basis for such a determination.
For each item identified in the inspection checklist, the technical specialists identify the ‘objective evidence’ examined in order to determine the category into which the item falls. Examples of appropriate objective evidence are the documents reviewed (reference the specific document numbers), the personnel interviewed (identify the names and responsibilities) and the plant conditions observed (describe the specific locations and details).
Furthermore, specific recommendations are made on how to correct the deficient conditions. Each recommendation is made after giving appropriate consideration to the specific deficiency needing attention, the indirect aspects related to the
6

deficiency and the root cause analysis of the basic cause of the deficiency; the results of this analysis may indicate the need for a higher level recommendation.
4. INSPECTION CHECKLIST
The fire safety inspection checklist has been prepared for fire safety inspections of a nuclear power plant by professional fire safety specialists. The methodology and contents of the checklist may also be used by regulatory or specialized third party organizations to conduct fire safety inspections of nuclear power plants. In addition, the checklist may be useful to the management of a nuclear power plant as a listing of the numerous elements that must be evaluated in order to determine the adequacy of the fire protection measures and manual fire fighting capability. The checklist will also provide guidance to a nuclear power plant for conducting a self- assessment of fire safety. However, it should not be used by non-specialists in fire protection, and self-assessment should not be considered a substitute for an independent fire safety inspection.
The checklist is intended for a small group of fire safety specialists specifically qualified by education and practical experience to evaluate the adequacy and effectiveness of the fire protection measures (both passive and active) and manual fire fighting capability provided at the plant. The checklist provides a listing of the fire protection elements to be considered. It is not all inclusive and should not limit the investigations of the fire safety specialists; rather, it should be considered as a minimum listing of items to be included in inspection and assessment.
