4 Part 1 : Operating Reactor Excellence

5 LTO and performance Safety and Performance of more 40 years Operating Npps? o Energy Availability Factor o 30 Y < NP<40 Y: 82% o NP> 40Y : 86% o Forced Loss Rate o 30 Y < NP<40 Y: 3.5% o NP> 40Y : 2.3 % 5

6 Failure Rate by Age (all unplanned power reductions) Less Failure Rate of More 40 years Operating Npps o Grand Modernization/ Replacement to get the extended Operating License based on PSR, LRA, Safety action plan. o Matured Operation Experiences

7 Benchmarking of Availability Planned Unavailability All reactor : 20.8% Best performers: 4.1%

8 Thermal Performance Monitoring and Optimization in NPPs Operation Mismatch between Reactor Thermal Power and Generator Power Output (MWe) oreactor power : 684 Mwe, 99.9% ogenerator output: 672 Mwe, 98.7% Match : 12 MWe (~ 1.2 %)

9 PLiMModels for LTO Member state approaches to PLiMfor LTO Organization structure Licensing requirements Scoping and screening method Evaluation of SSCs Feasibility study Documents package structure Implementation of PLiM for LTO 3.1. Comparison between different approaches 3.2. Implications of operating experience and lessons learned 3.3. Handling of design and licensing changes 3.4. Beyond design basis issues Technical issues to apply CAN, CZR, FRA, HUN, IND, CPR, KOR, RUS, SPN, USA

10 Outage Optimization : Challenge Outage Challenges How to control design change & replacement effectively? How to improve work control & foreign material exclusion effectively? How to manage & control contractors efficiently? How to assess the effectiveness of outage performance? Developinga new guidelines on the advanced Non-destructive examination techniques and experiences.

11 Coordinated Research Project Benchmark analysis of aged Cable through Condition Monitoring Technology o Thermal and Radiation Ageing effects Irradiation Cell Thermal (USA) Irradiation Thermobox

13 Part 2 : Safe Long Term Operation

14 How does IAEA support safe LTO? 1. Establishment of related IAEA Safety Standards Safety Guide SSG-48 - Ageing management and LTO 2. Fostering information exchange Working groups (IGALL Programme) Workshops (ageing management, LTO, PLIM) Conferences and technical meetings SALMIR database 3. Provision of peer review services SALTO Safety Aspect of LTO OSART LTO module Technical review services (design) 14

15 Safety Standards to Ageing Management and LTO SSG-48 Ageing Management and LTO (approved draft) SSG-25 Safety Guide on PSR (2013) SRS No 57 Safe LTO (2008) SRS No 82 IGALL Report (2015) SS No 26 SALTO Guidelines (2014) 15

16 Safety Guide SSG-48 on AM and LTO Provide comprehensive guidance on recommended ways of fulfillment of SSR-2/2 o Requirement 14: Ageing management, and o Requirement 16: Programme for long term operation Mainly focused on physical ageing but also includes management of technological obsolescence. Endorsed by Commission for Safety Standards (CSS) in April 2017 To be published in

17 Objectives of IGALL* Programme 1. Develop a living IGALL Safety Report as a guidance on recommended ageing management programmesand typical time limited ageing analyses 2. Provide guidance for NPPs with diverse technologies: PWR, BWR, WWER, CANDU, PHWR 3. Support systematic approach to managing of ageing as described in thesafety Guide SSG-48 on component/ structure level 4. Create an international network for exchange of operating experience in ageing management Established as an IAEA Extrabudge tary Programme in 2010 * IGALL : International Generic Ageing Lessons Learned 17

18 IGALL deliverables Published as an IAEA Safety Report SRS No.82 (April 2015) IGALL database on IAEA web site contains: 84 Ageing Management Programmes 28 Time Limited Ageing Analysis Technological obsolescence programme More than 2100 consolidated line items in Ageing Management Review tables IGALL is a living product updates of: Safety Report once in 5 years IGALL database every 2 nd year (2015, 2017,...) 18

19 Current Status of IGALL Active participation of app. 150 experts from 29 Member States (out of 30 operating NPPs), EPRI, EU JRC and OEDC/NEA IGALL Phase 3 ( ) to be completed in December 2017 IGALL Phase 4 planned for ( ) Steering Committee 1 representative per MS WG leaders IAEA QA Procedure IGALL Safety Report Edition 2018 WG1 -Mech. Components Up to 40 members WG2 EI&C components Up to 35 members WG3 -Civil structures Up to 30 members 19

20 SALTO* Peer Review Service Benefits of SALTO Peer Review Service: 1. Review of compliance with IAEA standards 2. Recommendations for improvement to reach the compliance 3. Opportunity for NPP staffto discuss their practices with experienced experts 4. Strengthening of public confidence to NPP 5. Support in licensing renewal procedure (or extension of operational permission procedure) * Safety Aspects of Long Term Operation 20

21 Standard SALTO Peer Review Scope Organisation and functions for LTO Current licensing basis (FSAR, PSR) Configuration/ modification management Scope setting of SSCs Review of plant programmes relevant to LTO Ageing management review Review of ageing management programmes Revalidation of time limited ageing analyses Human resources, competence and knowledge management for LTO 21

22 12 10 SALTO missions Expert mission based on SALTO Guidelines SALTO follow-up Pre-SALTO and SALTO

23 SALMIR database SALTO Mission Results database Contains results from SALTO missions, OSART missions with LTO module and follow-up visits from 2005 (Continually being updated) Posted on IAEA IGALL restricted website SALTO REVIEW FINDINGS Issues - Recommendations - Suggestions Good practices Mission Report SALMIR DB 318 Recommendations 168 Suggestions 39 Good practices

24 Summary Long Term Operation becomes a competitive power generation option High levels of safety and economic competitiveness Sufficiently trained personnel to carry out the work Continuously support MS to enhance safety and improve the reliability and performance Fostering information exchange Develop the guidelines with experiences and good practices Provides a peer review service (SALTO) in application of related IAEA Safety Standards SALMIR database provides results of SALTO missions IGALL programme is a network for experience exchange in ageing management 24
