  1. Operating Experience Feedback Process in Korea – focusing on closing the feedback loop - May 30, 2006 Korea Institute of Nuclear Safety Kim, MinChull Operational Safety Analysis Dept. Safety Preparedness Division Korea Institute of Nuclear Safety (KINS)k400kmc@kins.re.kr

  2. Contents • Introduction • OEF process in Korea (Utility) • OEF process in Korea (Regulatory body) • Closing the feedback loop • Corrective action tracking system first KINS

  3. 1. Introduction • Operating experience feedback process in Korea • Main elements of operating experience feedback process • Collection of operating experience • Storage, management and processing of collected information • Investigation and analysis for identifying lessons-learned • Applying identified lessons • Tracking implementation of lessons-learned • Utility : internal procedures • Regulatory body • Internal process • Periodic inspection on utility’s OEF process and implementation first KINS

  4. 2. OEF process in Korea (Utility) first KINS

  5. 3. OEF process in Korea (Regulatory body) first KINS

  6. 4. Closing the feedback loop • Characteristics of corrective action itself • Design modification dealt or linked by other regulatory process such as a review process on modifying an individual plant’s licensing basis • Generic issues applied to the related nuclear power plants • Relationship between events and corrective actions • Effectiveness of actions depends on the accuracy of analysis on the occurred event • So it is necessary to review and analyze the event considering: • the performance of the components related to the event; and • all information related to similar events occurred in the past • Proper corrective actions could prevent recurrence of similar events first KINS

  7. 4. Closing the feedback loop in Korea • The time of closing feedback: • The time that all approved corrective actions completed in a timely manner • under the suppose that corrective actions identified from specific operational experience are effective to prevent recurrence of similar events • need for development of the tracking system • The system will help: • To analyze an operating experience; • To monitor the status of the implementation; and • To ensure that the approved corrective actions completed properly. • In addition, we are also developing the ESCORTS (Event Sequence COding and ReTrieval System) for detailed management and classification of operating experience first KINS

  8. 5. Corrective action tracking system • Objectives • Management of the lesson-learned effectively and efficiently; • Monitoring utility’s implementation in a timely manner; and • Management of all information from the cradle to the grave. first KINS

  9. 5. Corrective action tracking system • Standardization of work flow • Users : regulatory body, utility • Main steps • Event report : utility • Investigation and analysis : regulatory body • Utility : self investigation & analysis • Administrative order : regulatory body • Implementation of corrective actions : utility • Review a plan and/or a results of implementation : regulatory body • If correct : terminate the review • If incorrect : re-implementation and/or complementation • Verification of the results of the implementation (inspection) : regulatory body first KINS

  10. 5. Corrective action tracking system • Main information • Reporting type • Verbal report, initial written report, detailed report • Investigation and analysis • Investigation report, collected material • Corrective action • Items, applied plants and due date • Plan and result of implementation • Results of review of the plan the results • Results of inspection for verifying appropriateness of implementation first KINS

  11. 5. Corrective action tracking system • Development of web-based system • Log-in page first KINS

  12. 5. Corrective action tracking system • Development of web-based system (cont’d) • Main page first KINS
