  3. TOPICS Legal framework Phases of oversight Regulatory functions Regulatory activities Conduct of inspections Construction inspection Inspector qualification

  4. LEGAL FRAMEWORK

  5. LEGAL FRAMEWORK Laws Regulations Guidance Engineering codes and standards

  6. HIERARCHY OF DOCUMENTS • Law on atomic energy • Law on radiation protection • Law on emergencies • ......................... NATIONAL LAWS • Site selection • Reactor licensing • Reactor operation • Decommissioning MANDATORY REQUIREMENTS • Technical guidance • Regulatory processes • Inspection guides • Training manuals GUIDANCE DOCUMENTS

  7. LAWS Enacted by National Assembly Establish authority of regulatory agency over safety matters Establish requirements for conduct of regulatory affairs May limit liability of vendors and operating company

  8. REGULATIONS / REQUIREMENTS Enacted by regulatory agency or ministry General standards and acceptance criteria Detailed requirements in some areas Govern all aspects of reactor design, construction and operation Legally binding on licensee Some regulations apply to the regulator

  9. GUIDANCE • Developed by regulatory agency • Not legally binding • Provide guidance to applicants and licensees: • Acceptable ways to comply with regulations • Form and content of submittals • Provide guidance to regulatory agency on: • Review of licensee submittals • Conduct of inspections • Regulatory processes

  10. CODES AND STANDARDS Developed by engineering / scientific societies Technical guidance on design, fabrication, installation, inspection, maintenance and repair of systems, structures and components Based on consensus of best technical practices Endorsed by regulatory agency for use by operating companies and vendors

  11. PHASES OF OVERSIGHT

  12. PHASES OF REGULATION Site approval Construction permit Construction oversight Operating license Commissioning

  13. PHASES (cont’d) Operations oversight License extension Decommissioning

  14. REGULATORY PROGRAMPHASES OF OVERSIGHT SITING CONSTRUCTION PERMIT CONSTRUCTION OPERATING LICENSE COMMISSIONING OPERATION DECOMMISSIONING

  15. NATIONAL NUCLEAR POWER PROGRAM Role of the Nuclear Regulatory Agency 1 2 3 4 5 6 7 8 9 10 11 12 13 14 YEAR

  16. SITE APPROVAL Site characteristics suitable to: Support construction Support operation Hazards to plant safety Seismic Suitability for EP

  17. CONSTRUCTION PERMIT Fundamentally sound reactor design Analysis demonstrates ability to handle accidents and transients Safety classification of SSC Safety requirements for SSC Ability of applicant to safely construct the plant

  18. CONSTRUCTION OVERSIGHT QA Codes and standards Adherence to CP Vendors

  19. OPERATING LICENSE Verify information presented in CP Engineering capability of as-built plant Operational controls Ability of applicant to operate safely Two approaches Open-ended license period plus periodic safety review Fixed license period plus license renewal

  20. COMMISSIONING Readiness to commence operation Sufficient trained staff Programs and procedures Management controls

  21. OPERATIONS OVERSIGHT Licensee performance Compliance with requirements and license Operator licensing Issue resolution Event response Plant modifications

  22. LICENSE EXTENSION Two options: periodic safety review or license renewal Periodic safety review Every ten years Full review of plant safety License renewal Every forty years Aging processes only

  23. DECOMMISSIONING Dismantle and dispose of contaminated structures Disposition spent fuel Decontaminate the site Decommissioning fund

  24. REGULATORY FUNCTIONS

  25. REGULATORY FUNCTIONS Rule-making Licensing, maintenance of license, and license renewal Enforcement Performance assessment Event / emergency response Technical issue resolution

  26. RULEMAKING Rules, regulations, requirements Administrative process Governed by national laws Include public and licensee involvement

  27. RULEMAKING (cont’d) Technical content based on: Engineering knowledge Research results Operating experience

  28. LICENSING Implements regulations for individual facility Specific ways of meeting requirements License provisions are legally binding Supporting information becomes the “licensing basis” Modifications to license License renewal

  29. ENFORCEMENT Notice of violation of regulations or license Possible monetary penalties Criminal penalties for flagrant violations

  30. PERFORMANCE ASSESSMENT Safety depends on licensee excellence Management commitment to safety culture Performance problems result in operational events and degraded plant conditions Revealed through inspections, operational events and performance indicators Significance determination process Graded response

  31. EVENT RESPONSE Immediate safety concerns Incident response International assistance Root cause analysis / event investigation Corrective action Graded agency response Possible generic action

  32. TECHNICAL ISSUE RESOLUTION Significant event or safety condition Reveals a new safety issue Individual plant remediation Generic action

  33. REGULATORY ACTIVITIES

  34. AGENCY ACTIVITIES Technical review Inspection/audit Event analysis Technical analysis Codes and standards activities Licensing of Plant Operators Research

  35. TECHNICAL REVIEW Detailed review of applicant / licensee submittals By staff who are expert in specific technical areas In accordance with agency requirements and guidance In support of licensing and oversight decisions

  36. INSPECTION AND AUDIT Direct observation of plant conditions and licensee activities By technical staff trained in inspection techniques To judge compliance with regulations and license provisions To assess safety of design and operation Provide basis for further agency action

  37. EVENT ANALYSIS Operating events challenge safety They reveal problems with plant condition and licensee performance Detailed analysis of significant events provide basis for technical resolution Trends and patterns of minor events reveal emerging safety issues International assistance

  38. TECHNICAL ANALYSIS Some aspects of nuclear technology require detailed technical analysis Nuclear core design Thermal and fluid behavior during normal operation and accidents Structural mechanics Chemical behavior of fission products Regulatory decisions in these and other areas require reliable analytical results

  39. CODES AND STANDARDSACTIVITIES Agencies endorse codes and standards for use by applicants and licensees Promotes efficiency of regulatory process Endorsement decisions must be based on thorough knowledge of content Staff participation in code activities assures quality of agency decisions

  40. LICENSING OF OPERATORS Plant operators impact safety Must have excellent knowledge, skills and experience Agency oversight of operator qualification: training and testing Many countries license plant operators

  41. RESEARCH New safety issues constantly emerge Due to operational events, advances in technology and aging processes Resolution often requires detailed experimental and theoretical analysis By experienced research organizations Regulator must be aware of research activities in the international community

  42. CONDUCT OF INSPECTIONS

  43. INTRODUCTION Inspections by the regulatory authority play a primary role in assuring activities are performed in accordance with governing regulations Inspection scheduling Enforcement

  44. INTRODUCTION Structure of this presentation Overview of inspection activities Types of inspections Inspection performance Guidance for inspectors Summary

  45. OVERVIEW OF INSPECTION Purpose of inspection activities: Verify compliance with regulations and license Verify compliance with implementing processes and procedures Verify adequacy of personnel

  46. OVERVIEW OF INSPECTION • Regulated entity’s quality assurance (QA) and quality control (QC) programs play an important role in assuring regulatory requirements are met

  47. OVERVIEW OF INSPECTION Outcomes of inspection activities include assurance that: effective implementing procedures exist and are being followed work is being satisfactorily accomplished risk determinations and other assumptions used in plant design and operations are not being undermined by poor or inadequate practices

  48. OVERVIEW OF INSPECTION Inspection outcomes (cont’d): public acceptance of the adequacy of plant construction, operations, and maintenance adequate resolution of identified issues public confidence in regulatory oversight adequate corrective action in response to findings identification of appropriate topics for discussion with licensee management during periodic performance review meetings

  49. OVERVIEW OF INSPECTION • Inspections and enforcement motivate compliance • Regulated entity is responsible • Challenges exist • Allegations • Enforcement • Importance of inspection findings

  50. TYPES OF INSPECTIONS Key types of inspections are: Routine Specialist Vendor Team
