2 Outline 1. Challenges Faced by AECL post Fukushima 2. Phase 2 of AECL Restructuring The Nuclear Laboratories 3. Technical Support System within AECL AECL - OFFICIAL USE ONLY / À USAGE EXCLUSIF - EACL 2

3 AECL s Canadian Footprint Manitoba Chalk River Laboratories Ontario NPD Quebec Gentilly 11 LaPrade Whiteshell Laboratories New Brunswick Glace Bay Douglas Point PROTECTED - SENSITIVE / PROTÉGÉ - DÉLICAT Port Hope / Gransby NPD = Nuclear Power Demonstration

4 Chalk River Laboratories 3700 Hectares Largest nuclear S&T organization in Canada ~2700 staff Waste Management Areas Research facilities, including two test reactors: Zed-2 and NRU AECL - OFFICIAL USE ONLY / À USAGE EXCLUSIF - EACL 4

5 National Research Universal (NRU) Safety system upgrades Integrated Safety Review in 2011 In Fukushima-like event, single largest source term at CRL Key differences in SA progression between NRU and CANDU NPPs In-service date: MWth, 227 vertical lattice sites Isotope production; experimental loops; Neutron Beam Centre AECL - OFFICIAL USE ONLY / À USAGE EXCLUSIF - EACL 5

6 Post-Fukushima Activities (1) Enhance Emergency Response Capability Portable pumping equipment to supplement Qualified Emergency Water System (QEWS) Portable DGs New earth-moving equipment Enhanced fire-fighting capability Supplemental equipment to support loss of power in the Emergency Operating Centre Centralized storage facility Equipment to enhance SAMG effectiveness; e.g. new power tie-ins, water-injection ports Identified responsibilities in the Canadian Federal Nuclear Emergency Plan (FNEP) AECL - OFFICIAL USE ONLY / À USAGE EXCLUSIF - EACL 6

7 Post-Fukushima Activities (2) Severe Accident Management Program SAMP includes a number of activities building on reviews and benchmarks Re-assessed earthquake, prolonged lost of power, and flood mitigation readiness Stress testing on earthquake, flood, tornado, external fire, aircraft SAMGs under development based on Westinghouse Owners Group framework Outlines multiple methods to restore and retain core cooling, emergency power, confinement integrity etc. Consists of control room guides, severe accident exit guides, and diagnostic flow chart and computational aids AECL - OFFICIAL USE ONLY / À USAGE EXCLUSIF - EACL 7

8 AECL Restructuring 2 Phases Phase 1: Completed November 2011 with divestiture of AECL s CANDU Reactor Division to SNC Lavalin (CanduEnergy) Phase 2: AECL s existing labs will be operated under Government- Owned Contractor-Operated (GoCo) model Procurement underway; targeted completion date: October 2015 Future governance for the lab closely parallels the UK model AECL will be a much smaller Crown Corporation (~50 people) that oversees the GoCo contract (similar to the role performed by the UK Nuclear Decommissioning Authority) Majority of the current staff (~3400 people) will be transferred to a Site Operating Company (e.g. Sellafield) called: Canadian Nuclear Laboratories AECL - OFFICIAL USE ONLY / À USAGE EXCLUSIF - EACL 8

9 Canadian Nuclear Laboratories (CNL) As of 2014 November 3, everything that has traditionally been associated with AECL will be performed by the Canadian Nuclear Laboratories CNL will become a wholly-owned subsidiary of AECL Licences transferred Firstname.Lastname@cnl.ca Procurement will end October 2015 when control of CNL (the share ) is transferred to the successful GoCo contractor, and the new AECL is fully operational AECL - OFFICIAL USE ONLY / À USAGE EXCLUSIF - EACL 9

10 Defined Missions for CNL 1. Support government in its obligation to manage historic and legacy liabilities 2. Provide nuclear science and technology capabilities and services to federal government departments 3. Support the nuclear industry s need for Commercial R&D One Potential Mission: 4. Implement an industry-driven, cost-shared nuclear innovation agenda AECL - OFFICIAL USE ONLY / À USAGE EXCLUSIF - EACL 10

11 Within Canada Technical Support System within AECL Close collaboration through an industry association called CANDU Owners Group (COG); brings together expertise from utilities, other Canadian nuclear S&T organizations Greater collaboration/interactions in future with other federal departments; e.g. Health Canada, Canadian Border Security, Environment Canada, CNSC Outside Canada Collaborative e.g. IAEA, CSNI, IRSN, Gen IV, etc. Suppliers e.g. Halden, NITI, Saclay, etc AECL - OFFICIAL USE ONLY / À USAGE EXCLUSIF - EACL 11

12 In-vessel Retention Phenomena Tube sheet boundaries must be preserved Conducted heat to the calandria vault water cannot exceed the CV CHF Crust/CV wall interaction Does stratification occur? RASPLAV and MASCA very informative, but melt composition for PHWR and LWR different AECL - OFFICIAL USE ONLY / À USAGE EXCLUSIF - EACL 12

17 Managing Capabilities Centres of Excellence Nuclear & Radioactive Materials Management Irradiation & Post-Irradiation Services Nuclear Safety, Security & Risk Management Materials & Chemistry in Nuclear Applications Systems Engineering Hydrogen & Hydrogen Isotope Management Radiation Biology, Radioecology & Dosimetry Advanced Nuclear Fuel & Fuel Cycles Advanced Computing, Modeling & Simulation Environmental Remediation and Nuclear Waste Management People, Facilities, Key Suppliers, Collaborations AECL - OFFICIAL USE ONLY / À USAGE EXCLUSIF - EACL 17

18 Summary Post-Fukushima activities are well-defined and good progress is being made The restructuring of the Laboratories provides an S&T mandate for the AECL/CNL in the future Restructuring provides an opportunity for explicitly strengthening cooperation/collaboration on TSOactivities, particularly with the Canadian regulator International collaboration will continue to be imperative, but uniqueness of the CANDU design requires a strong enduring capacity within Canada Centres of Excellence are a good vehicle for framing and maintaining capabilities within CNL AECL - OFFICIAL USE ONLY / À USAGE EXCLUSIF - EACL 18
