CANDU reactor operation has very low emissions to minimize environmental impact. Our CANMOX solution additionally features a zero-liquid emission design. Following our traditional CANDU reactor design practice, the EC6 incorporates two passive, fast-acting shutdown systems that are physically and functionally independent of each other. EC6 safety systems are designed to ensure reactor shutdown, remove decay heat and prevent radioactive releases during events and accidents. The principles of separation, diversity and high reliability apply to the design of the safety systems that perform the safety functions, including shutdown systems, emergency core cooling system and containment systems. The traditional emergency water supply system has been upgraded to become an enhanced emergency heat removal system (EHRS), operating as an alternate heat sink for residual decay heat following postulated low probability accidents that render normal heat sinks unavailable. High degrees of redundancy within systems ensure safety functions can be carried out.

  • Fuel Cycle Flexibility in CANDU P.G
    IAEA-SM-353-5P Fuel Cycle Flexibility in CANDU P.G. Boczar XA9949933 Director, Fuel and Fuel Cycle Division, AECL Chalk River Laboratories, Chalk River, Ontario, Canada No single fuel-cycle path is appropriate for all countries. Many local and global factors will affect the best strategy for an individual country. Fuel-cycle flexibility is an important factor in an ever-changing, and unpredictable world. CANDU is an evolutionary reactor, offering a custom fuel cycle to fit local requirements. Its unsurpassed fuel-cycle flexibility can accommodate the widest range of fuel-cycle options in existing CANDU stations. In the short term, the CANFLEX® bundle is nearing power reactor implementation. The demonstration irradiation of 26 bundles in the Pt. Lepreau power station in New Brunswick, Canada, started this September, and a water-CHF test will take place later this year that will confirm the improvement in thermalhydraulic performance. CANFLEX provides enhanced operating and safety performance through a reduction in peak linear element ratings, and a significant increase in critical channel power. CANFLEX will be the near-term carrier of advanced fuel cycles. While natural uranium fuel provides outstanding advantages, the use of slightly enriched uranium (SEU) in CANDU offers even lower fuel cycle costs and other potential benefits, such as uprating capability through flattening the radial channel power distribution. Recycled uranium (RU) from reprocessing spent PWR fuel is a subset of SEU that has significant economic promise. The use of SEU/RU is the first logical step from natural uranium in CANDU. For countries having LWR reactors, the ability to use low-fissile material in CANDU reactors offers a range of unique synergistic fuel cycle opportunities.

  • Simulation of In-Core Dose Rates for an Offline CANDU Reactor
    Simulation of In-Core Dose Rates for an Offline CANDU Reactor by Jordan Gilbert Bachelor of Nuclear Engineering (Hons), University of Ontario Institute of Technology, 2013 A THESIS SUBMITTED IN PARTIAL FULFILLMENT OF THE REQUIREMENTS FOR THE DEGREE OF Master of Applied Science in The Faculty of Energy Systems and Nuclear Science Nuclear Engineering Supervisor(s): Ed Waller, University of Ontario Institute of Technology Scott Nokleby, University of Ontario Institute of Technology Examining Board: Glenn Harvel, University of Ontario Institute of Technology External Examiner: Emily Corcoran, Royal Military College of Canada THE UNIVERSITY OF ONTARIO INSTITUTE OF TECHNOLOGY April 2016 ©Jordan Gilbert 2016 Abstract This thesis describes the development of a Monte Carlo simulation to predict the dose rates that will be encountered by a novel robotic inspection system for the pressure tubes of an offline CANDU reactor. Simulations were performed using the Monte Carlo N-Particle (MCNP) radiation transport code, version 6.1. The radiation fields within the reactor, even when shut down, are very high, and can cause significant damage to certain structural components and the electronics of the inspection system. Given that the robotic system will rely heavily on electronics, it is important to know the dose rates that will be encountered, in order to estimate the component lifetimes. The MCNP simulation was developed and benchmarked against information obtained from Ontario Power Generation and the Canadian Nuclear Laboratories. The bench- marking showed a good match between the simulated values and the expected values. This simulation, coupled with the accompanying user interface, represent a tool in dose field prediction that is currently unavailable.

  • Dynamic Analysis of the Thorium Fuel Cycle in CANDU Reactors

The recycling is performed through the dry process fuel technology which has a proliferation resistance. For the once-through fuel cycle model, the existing nuclear power plant construction plan was considered up to 2016, while the nuclear demand growth rate from the year 2016 was assumed to be 0%. After setting up the once-through fuel cycle model, the thorium fuel CANDU reactor was modeled to investigate the fuel cycle parameters. In this analysis, the spent fuel inventory as well as the amount of plutonium, minor actinides and fission products of the multiple recycling fuel cycle were estimated and compared to those of the once-through fuel cycle. From the analysis results, it was found that the closed or partially closed thorium fuel cycle can be constructed through the dry process technology. Also, it is known that both the homogeneous and heterogeneous thorium fuel cycles can reduce the SF accumulation and save the natural uranium resource compared with the once-through cycle.

  • THE NEXT GENERATION CANDU 6 J.M. HOPWOOD XA0053559 Atomic Energy of Canada Ltd, Mississauga, Ontario, Canada
    IAEA-SM-353/29 THE NEXT GENERATION CANDU 6 illinium J.M. HOPWOOD XA0053559 Atomic Energy of Canada Ltd, Mississauga, Ontario, Canada Abstract AECL's product line of CANDU 6 and CANDU 9 nuclear power plants are adapted to respond to chang- ing market conditions, experience feedback and technological development by a continuous improvement process of design evolution. The CANDU 6 Nuclear Power Plant design is a successful family of nuclear units, with the first four units entering service in 1983, and the most recent entering service this year. A further four CANDU 6 units are under construction. Starting in 1996, a focused forward-looking development program is under way at AECL to incorporate a series of individual improvements and integrate them into the CANDU 6, leading to the evolutionary development of the next-generation enhanced CANDU 6. The CANDU 6 improvements program includes all aspects of an NPP project, including engineering tools improvements, design for improved constructability, scheduling for faster, more streamlined commissioning, and improved operating performance. This enhanced CANDU 6 product will combine the benefits of design provenness (drawing on the more than 70 reactor-years experience of the seven operating CANDU 6 units), with the advantages of an evolutionary next- generation design. Features of the enhanced CANDU 6 design include: • Advanced Human Machine Interface - built around the Advanced CANDU Control Centre. • Advanced fuel design - using the newly demonstrated CANFLEX fuel bundle. • Improved Efficiency based on improved utilization of waste heat. • Streamlined System Design - including simplifications to improve performance and safety system reliability. • Advanced Engineering Tools, - featuring linked electronic databases from 3D CADDS, equipment specifi- cation and material management.

  • Candu Fuel-Cycle Vision Xa9953247
    CANDU FUEL-CYCLE VISION XA9953247 P.G. BOCZAR Fuel and Fuel Cycle Division, Chalk River Laboratories, Atomic Energy of Canada Limited, Chalk River, Ontario, Canada Abstract The fuel-cycle path chosen by a particular country will depend on a range of local and global factors. The CANDU® reactor provides the fuel-cycle flexibility to enable any country to optimize its fuel-cycle strategy to suit its own needs. AECL has developed the CANFLEX® fuel bundle as the near-term carrier of advanced fuel cycles. A demonstration irradiation of 24 CANFLEX bundles in the Point Lepreau power station, and a full-scale critical heat flux (CHF) test in water are planned in 1998, before commercial implementation of CANFLEX fuelling. CANFLEX fuel provides a reduction in peak linear element ratings, and a significant enhancement in thermalhydraulic performance. Whereas natural uranium fuel provides many advantages, the use of slightly enriched uranium (SEU) in CANDU reactors offers even lower fuel-cycle costs and other benefits, such as uprating capability through flattening the channel power distribution across the core. Recycled uranium (RU) from reprocessing spent PWR fuel is a subset of SEU that has significant economic promise. AECL views the use of SEU/RU in the CANFLEX bundle as the first logical step from natural uranium. High neutron economy enables the use of low-fissile fuel in CANDU reactors, which opens up a spectrum of unique fuel-cycle opportunities that exploit the synergism between CANDU reactors and LWRs. At one end of this spectrum is the use of materials from conventional reprocessing: CANDU reactors can utilize the RU directly without re-enrichment, the plutonium as conventional mixed-oxide (MOX) fuel, and the actinide waste mixed with plutonium in an inert-matrix carrier.
