Who are we & What we do? ØNuclear Safety Technical Support Center of CAEA: National regulatory organization ØCore duty: daily/annual inspection of nuclear facilities, develop regulations/standards for radiation and nuclear safety, review and evaluate license applications, draft national decommission plan ØTarget facilities: research reactor operators/nuclear fuel cycle facilities/tailing ponds/nuclear equipment manufactories/nuclear material holders Nuclear Safety Technical Support Center of

Current situation of nuclear safety culture construction in China ØThe first assessment: Qinshan NPP, September 2011, CNNC Nuclear Power Company, based on the 8 principles of excellent nuclear safety of CNNC. ØStrong calling for developing relevant standards & carrying out formal assessment activities: 36 NPPs in operation with a total installed capacity of 33 million 500 thousand kilowatts; 21 NPPs under construction with a total installed capacity of 23 million 435 thousand kw, until December, 2016. Ø“The Nuclear Safety Culture Policy Statement”, released in 2014, 8 traits. ØNuclear safety culture assessment document system of NPPs. Ø“Nuclear safety culture features”, NNSA-HAJ-1001 -2017, detailed explanation of the 8 traits of the statement, 36 attributes and 154 examples of practice in NPPs. Work to be. Support done: Center standards Nuclear Ø Safety Technical of & guidelines for nuclear facilities except

Case 1: nuclear safety culture assessment of NPPs in CNNCFramework Ø 10 Principles for Excellence in CNNC Nuclear Safety Culture, 10 traits, 46 attributes. ØAccording to IAEA/INPO/WANO & their own experience, combined with the “Policy statement” and ”Traits of a healthy nuclear safety culture” ØPersonal accountability(PA. 1 -PA. 3) ØQuestioning attitude(QA. 1 -QA. 4) ØCommunication(CO. 1 -CO. 4) ØLeadership accountability(LA. 1 -LA. 7) ØRespectful work environment(WE. 1 -WE. 6) ØDecision-making(DM. 1 -DM. 4) ØNuclear specificity(NS. 1 -NS. 5) ØProblem identification and resolution(PI. 1 -PI. 4) ØLearning organization(LO. 1 -LO. 6) ØPublic relation(PR. 1 -PR. 3) Nuclear Safety Technical Support Center of

Case 1: nuclear safety culture assessment of NPPs in CNNC - Procedure ØPreparation: organize a team, assessor training, questionnaire survey, AIP file review, operator preparation(12 months before the assessment) ØOn-site assessment: interview, observation, document review(1 week) ØFollow-up actions: assessment reports, corrective action plans, continuous tracking & assessment(24 months) Survey data Example: Observation record Nuclear Safety Technical Support Center of Survey result analysis

Case 1: nuclear safety culture assessment of NPPs in CNNC – result & challenge Ø 4 assessment activities: Qinshan Phase 1, Jiangsu Nuclear Power Corp, CNNC Nuclear Power Operation Management Co. , Ltd, Sanmen Nuclear Power Corp ØSanmen: 1058 questionnaires, 63 on-site interviews, 559 data points in 2014 ØStrong: LA. 1 - safety commitment; NS. 1 - recognize the uniqueness of nuclear technology; PI. 3 - timely and effective solution; QA. 2 - pause when uncertain. ØWeak: WE. 1 - respect each other; LO. 5 - training; LA. 5 - provide resources; PI. 2 problem evaluation. ØChallenge: conflict - nuclear safety culture and conventional safety culture; loss dispersion and loss of experienced personnel due to large number of NPPs started construction at the same time; diluted – non-nuclear-field personnel/contractors. Nuclear Safety Technical Support Center of

Case 2: North nuclear fuel element Co. , Ltd. Framework Øfocus on timely improvements of behavior ØFramework: 11 core concepts of Du. Pont STOP(Safety Training Observation Program) ØThe six step procedure: Observation-Praise-Discussion – Communication-Inspiration-Thanks. ØEncourage safety behavior-repeated safety behavior forms physical memory-behavior change attitudes-improvement in safety sense ØOn-site observation management system Nuclear Safety Technical Support Center of

Case 2: North nuclear fuel element Co. , Ltd. -Practice ØObserver team: management personnel at all level, technical personnel. ØObserver training: operation procedures ØOn-site observation ØDiscussion Seminar with front-line workers ØInternal meeting of observation team ØData and documents: observation & guide record table, data statistics table, observation report, improvement tracking list, inspiration list. ØAppraisal activities: model teams, good practices, excellent observers ØExample of good practices: Hand gesture communication in noisy working environment; making "praise safety behavior" board Nuclear Safety Technical Support Center of

North nuclear fuel element Co. , Ltd. -Practice Ø 2016. 3. 22 – now, 45 intensive observations, 168 cross observations, 407 independent observations, 575 observation reports Øan observer team of 76 personnel, an independent on-site observation working group. ØIdentified 1208 good practices, 1119 unsafe behaviors and hidden dangers, 654 corrective actions were taken immediately, and put forward 1439 improvement items (completed 1365 items) and 345 inspiration items (303 completed) ØImprovement direction: revise documents, analyze the root cause, bring in higher leadership, strengthen front-line worker learning.
