1 Nuclear Safety Supervision and Control in China Y.ZHAO DDG, Dept. of Nuclear Installation Safety Supervision,MEP (NNSA) 8 Oct. 2013

2 Ⅰ.National Nuclear Safety Administration Regulation Responsibility NNSA is regulator in China for: -- nuclear safety; -- radiation safety ; --radiological environment management. Regulation System Licensing system; two levels management: centre government and province;

3 NPPs in China 红沿河 46 台 -- 在建核电机组 29, 运行 17 台 Page /12/16 防城港 昌江 海阳石岛湾 田湾 宁德福清大亚湾 岭澳阳江台山 秦山一 方家山秦山二秦山三三门

4 Regulation Scope NPPs, research reactors and nuclear fuel cycle facilities; Nuclear technology application; Uranium (thorium) mining and NORM; Facilities for radioactive waste processing and disposal; Electromagnetism radiation device and facility.

5 Ⅱ.Legislation of Nuclear Safety Regulations Law Government Regulations Department Rules Safety Guides Technical Documents

6 Issued laws of nuclear and radiation safety Act of Environmental Protection; Act of Prevention and Control of Radioactivity Pollution; Act of Environment Impacts; Nuclear Safety Law in the preparation;

7 Issued administrative regulation for nuclear and radiation safety Regulations on the Safety Regulation for Civilian Nuclear Installations Emergency Management Regulations for Nuclear Accidents of Nuclear Power Plant Regulations on Nuclear Materials Control Regulations on the radiation protection for radioactive isotope and irradiation device

8 Issued administrative regulation of nuclear and radiation safety Regulations on Supervision and Control of Civil Nuclear Safety Equipment Regulations on Safety Management of Transport of Radioactive Substance Regulations on Safety Management of Radioactive Waste

9 Department Rules and guides Nuclear power plant design safety regulations Nuclear power plant operation safety regulations

10 Ⅲ.Organization System of NNSA Advisory Committee on Nuclear Safety MEP (NNSA) Provincial agencies for radiation safety and environment (31) Administration Office NRD 1 NRD 2 NRD 3 Internati onal Cooperation Office Others (HR, laws and regulation etc.) Technical Support Center Nuclear Inspection Offices (6)

11 NNSA improved in past 5 year, especially after Fukushima accident. Human resource doubled : now 1100 staff Headquarter: three technical departments, and one international cooperation office, staff 85 Six Regional offices, 331 Two TSOs, NSC: 600, RMC: 100 staff Regular Budget doubled: RMB 200 million in 2011, and in 2013, 390 million.

12 Training for new staff: general training for officers five-month training course; half-year training; One-year on-the-job trainng;

13 Ⅳ. Post-Fukushima Requirements for NPP Actions after the Fukushima nuclear accident, Action 1: conformity review with regulations and standards : Comprehensive Safety Examination Action 2: evaluation of safety margins: Safety Margin Assessment for External Event Action 3: studying of new safety requirements Nuclear Safety Plan

14 Post-Fukushima Requirements for NPP Improvement requirements for nuclear power plants. overall requirement; specific requirement The specific requirements would be implemented in three phases: short-term; medium; and long-term items

15 Overall requirements To pay close attention to investigation into Fukushima accident, getting feedback, evaluating improvements; To enhance the pre-warning and response ability against external disasters; To upgrade the monitoring and emergency ability, emergency resources and ability sharing; To improve the public communication mechanism, wage a public information campaign;

16 specific requirements (Short-term items) 1. Checking and completing the water tightness of cable /pipe penetrations, doors/windows and ventilation ports; 2. Strengthening the effectiveness of earthquake monitoring system; 3.Setting up extra mobile power, pumps and providing to maintain core cooling and monitoring capacity after serious accidents.

17 specific requirements (Medium and long-term items) 1. serious accidents management guideline ; 2. ability and reliability of system and equipments for serious accidents; 3. conducting probability safety analysis for external events; 4. renovation for flood-prevention; 5. evaluation of the effect of earthquake-triggered tsunami ; 6. complete the emergency monitoring plan in case of serious accidents; 7. analyzing and evaluating functions and inhabitability of emergency control center;

18 overall progress Up to now: Short-term safety improvements have been completed. medium and long-term safety improvements: Most of the improvements have been completed, others are still in progress.
