  1. Radiological ControlCurrent Concerns andIndustry Events TVAN Technical Training Health Physics (RADCON) Initial Training Program

  2. Enabling Objectives • Apply Error Prevention tools. • Identify Two Types of NRC Notifications • Identify Two Organizations Promoting Excellence in the Nuclear Power Industry • Identify Three Types of Event Reports • Evaluate Events on Summary Worksheet • Identify Major RADCON Concern • Name Four Other Areas of Concern TVAN Technical Training Health Physics (RADCON) Initial Training Program

  3. SAFER • Summarize Critical Steps • Anticipate Errors at Critical Steps • Foresee Consequences of Errors • Evaluate Defenses, Barriers & Contingencies • Review Experience TVAN Technical Training Health Physics (RADCON) Initial Training Program

  4. TVANHuman Performance Initiative • Protect People and the Plant From Human Error through: • Aggressive Control of Defense-in-Depth • Rigorous Use of Error-Prevention Techniques TVAN Technical Training Health Physics (RADCON) Initial Training Program

  5. Error Prevention Tools - 1 • Two-Minute Rule • Procedure Use & Adherence Independent Verification Second Party Verification • Effective Communication Three-Way communication Phonetic Alphabet TVAN Technical Training Health Physics (RADCON) Initial Training Program

  6. Error Prevention Tools - 2 • Self-Checking STAR – Stop, Think, Act, Review Flagging • Peer-Checking • Questioning Attitude QV&V – Qualify, Validate, & Verify Stop When Unsure TVAN Technical Training Health Physics (RADCON) Initial Training Program

  7. NRC Concerns Notices • Licensee Event Reports (LERs) 10 CFR 50.73 • Information Notices (INs) TVAN Technical Training Health Physics (RADCON) Initial Training Program

  8. Nuclear IndustryImprovement Organizations • Institute of Nuclear Power Operations (INPO) Promote Safety, Reliability and Excellence • World Association of Nuclear Operators (WANO) Maximize Safety & Reliability by Exchanging Information and Encouraging Communications TVAN Technical Training Health Physics (RADCON) Initial Training Program

  9. Event Reports • INPO/WANO Operating Experience Report (OE) • INPO/WANO Significant Event Notification (SEN) • INPO/WANO Significant Event Report (SER) • INPO/WANO Significant Operating Experience Report (SOER) • INPO/WANO Operations and Maintenance Report (O&MR) TVAN Technical Training Health Physics (RADCON) Initial Training Program

  10. Unplanned ExposuresWeaknesses in Defenses • SOER 2001-01 • Complying with Administrative Controls • Human Performance • Insufficient Training • Incorporation of Operating Experience • Inadequate Management Participation TVAN Technical Training Health Physics (RADCON) Initial Training Program

  11. Radiological Concerns • Unplanned Radiation Exposures (Major Concern) • Contamination/DRPs • Intakes/Internal Exposures • High Radiation Areas • Radiography TVAN Technical Training Health Physics (RADCON) Initial Training Program

  12. Common Causes ofRadiography Events • Postings not Understood • Assumptions rather than Verification • Inadequate Surveys • Inadequate Evaluation of Adjacent Dose Rates • Radiological Personnel Unfamiliar with Radiography Posting Requirements TVAN Technical Training Health Physics (RADCON) Initial Training Program

  13. Adverse Trends inRadiological Protection Events • Common Causes: • Insufficient Radiological Controls • Insufficient Line Management Oversight • Knowledge of New Equipment Limits • Inadequate Dose Monitoring • Over Reliance on Knowledge & Skills ofContract & RadCon Workers • Lack of Questioning Attitude TVAN Technical Training Health Physics (RADCON) Initial Training Program

  14. Barrier Analysis Barriers Associated with Events/Barriers Failed TVAN Technical Training Health Physics (RADCON) Initial Training Program

  15. Barrier Analysis ReportHighest Five Categories • Unplanned Dose (28%) • Uptakes (Internal Exposures) (19%) • Personnel Contamination (15%) • High Radiation Areas (9.5%) • Radiography & ALARA Planning (8% each) TVAN Technical Training Health Physics (RADCON) Initial Training Program

  16. Barrier Analysis ReportImportant Recommendations • More Use of Staytimes • Workers Self-Monitor Dose • Improve ALARA Planning • Survey After Removing Shielding • Monitor Dose Rates Approaching Limits • Compare As-Found Radiological Conditions with Forecast TVAN Technical Training Health Physics (RADCON) Initial Training Program

  17. Barrier Analysis ReportImportant Recommendations • Clarify Radiology Responsibilities • ALARA Planning Identify Airborne Risks • Use CAMs During Refuel Floor Work • Strengthen Controls for DRPs • Evaluate Equipment Release Practices • Thorough Evaluation of Whole Body Monitor Alarms TVAN Technical Training Health Physics (RADCON) Initial Training Program

  18. Performance Indicators • Provide Quantitative Indication of Plant Performance • Trend Performance & Progress • Set Challenging Goals for Improvement • Compare Performance with Others • Adjust Priorities & Resources TVAN Technical Training Health Physics (RADCON) Initial Training Program

  19. NRCPerformance Indicators • Zero Unplanned Exposures • Zero Overexposures • Zero High Radiation Area Violations TVAN Technical Training Health Physics (RADCON) Initial Training Program
