1 2013 Regulatory Oversight Summary Pickering and Darlington Pickering Community Advisory Council September 16, 2014 Miguel Santini e-doc # (PPT) e-doc # (PDF)

2 Outline Highlights Industry challenges Regulatory focus and compliance strategy Performance ratings Station specific issues Other topics 2

3 Highlights for the Industry No serious process failures at any nuclear power plant (NPP) No radiation dose to the public above the regulatory limit No radiation dose to workers above regulatory limits No radiological releases to the environment above derived release limits Accident frequency and severity rates were low Canada continues to meet its international obligations regarding the peaceful use of nuclear energy Safe Nuclear Power Generation 3

4 Industry Challenges Safety analysis Re-assessment of some postulated accident scenarios Assessment of the aging of CANDU reactors Improvements to Probabilistic Safety Assessment (PSA) methodologies Life management of aging facilities Life extension Decommissioning Response to Fukushima Daiichi accident Closure of Fukushima action Items Resolution of site-specific issues Implementing safety enhancements 4

5 Regulatory Focus Oversight of aging facilities Operation beyond assumed design life of 210,000 equivalent full power hours (EFPH) Preparation for life extension Transition from operation to safe storage Continuous safety improvements Implementation of new regulatory documents and industry standards Fukushima - accident risk reduction Public protection Improvements to accident management and emergency response Distribution of iodine thyroid blocking agents (potassium iodide pills) Public communication Risk tolerance Continued commitment to regulatory excellence 5

6 Compliance Verification Program The safety performance of NPPs is determined by CNSC staff using the results of activities planned through the compliance verification program. Compliance activities include surveillance and monitoring by full-time onsite inspectors, announced and unannounced inspections and desktop reviews. All compliance activities are fully documented and record the objective evidence that is the basis of the compliance results. 142 inspections conducted, led by 23 site inspectors. Over 1,400 findings derived from compliance activities. Risk-informed and performance-based approach 6

7 Performance Rating Methodology Current rating methodology established in 2010 Based on multiple sources of inputs Inspections, field rounds, follow-ups, desktop reviews Integration of inspection findings for each specific area Computational method and professional judgment Results of assessments in all safety and control areas (SCAs) SCA ratings combined to give the integrated plant ratings (IPRs) for each NPP Assessed against safety performance objectives and criteria Safety and Control Area Management System Human Performance Management Operating Performance Safety Analysis Physical Design Fitness for Service Radiation Protection Conventional Health and Safety Environmental Protection Emergency Management and Fire Protection Waste Management Security Safeguards and Non-Proliferation Packaging and Transport Integrated Plant Rating 7

9 National Benchmarking: Accident Frequency 5.0 Ontario Workplace Safety (ON workplaces) WorkSafe NB (NB workplaces) WorkSafe BC (BC workplaces) Canadian Electricity Association (CEA) CNSC Canadian Nuclear Power Industry Accident Frequency (fatalities and injuries per 200,000 person-hours) The nuclear industry leads in safety culture 9

10 National Benchmarking: Annual Dose to the Public 10 Annual Natural Background for Canada (1.8 msv) Annual Dose to the Public (msv) Annual Dose Limit to the Public (1 msv) 1,000 times below the public dose limit 0 Bruce site Darlington Pickering Gentilly-2 Point Lepreau Continues to be safe to live in the vicinity of an NPP Dose (msv) 10

11 Darlington Darlington Darlington Nuclear Generating Station is located on the shores of Lake Ontario and consists of four units. 11

12 Safety Performance Highlights - Darlington Good Practices Conventional health and safety Accident frequency remained low Accident severity rate decreased substantially Security Equipment modernization and upgrades underway Integration of onsite and local security force response Ensuring worker safety and security 12

13 Safety Performance Highlights - Darlington Regulatory Focus Management system and organization Implementation of centralized Business Transformation Initiatives (BTI) Changes to management system and organization Preparation for refurbishment Adherence to project timeline Reactor units approaching assumed design life of 210,000 equivalent full power hours (EFPH) CNSC staff assessment of integrated safety review (ISR) completed in July 2013 Global assessment report (GAR) and integrated implementation plan (IIP) submitted in Dec Addressing challenges for refurbishment 13

14 Pickering Pickering Pickering Nuclear Generating Station is located on the shores of Lake Ontario and consists of 6 operating units and 2 units in safe storage. 14

15 Safety Performance Highlights - Pickering Good Practices Radiation protection (RP) Implementation of initiatives to reduce worker exposures Continuous improvements in the RP program effective in protecting workers Security Equipment modernization and upgrades underway Strengthening site access security and access control measures Reducing risk to workers 15

16 Safety Performance Highlights - Pickering Regulatory Focus Management system and organization Implementation of centre-led Business Transformation Initiatives (BTI) Changes to management system and organization Fitness for service of aging components Verification of operation up to 247,000 EFPH Preparation for ending commercial operations Plans to ensure safe operation during period until end of operations in 2020 Preparing for end-of-life 16

17 OTHER TOPICS 17

18 Pre-Distribution of iodine thyroid blocking (ITB) agents (potassium iodide pills) Draft REGDOC Nuclear Emergency Preparedness and Response Expected to be published in fall 2014 Implementation plan through the Licence Condition Handbook The licensee to provide the necessary resources to ensure that ITB agents are pre-distributed within a 10 km zone by December 31, 2015 Canadian public is protected 18

19 Darlington Legal Challenges Darlington New Nuclear Project New nuclear power plant project deferred OPG collecting information to assist design activities In May 2014, Federal court decided on the judicial review of environmental assessment (EA) and site licence Decision is under appeal Darlington Refurbishment EA under judicial review Heard by Federal Court on May 6, 2014 Written presentations submitted during the summer CNSC decision on EA remains valid until Court says otherwise 19
