candu reactor advantages and disadvantages

Heavy water has a heavier isotope of hydrogen, , or deuterium, instead of regular hydrogen, . INTRODUCTION: Reactors play a major role in many industries involving the chemical transformation of substances. "The CANDU Reactor" Nuclear Technology: Exploring Possibilities. 3 4 5 2 7 1 6 8 End View 1 Zircaloy Bearing Pads 2 Zircaloy Fuel Sheath 3 Zircaloy End Cap 4 Zircaloy End Support Plate … Nuclear reactor - Nuclear reactor - Liquid-metal reactors: Sodium-cooled fast-neutron-spectrum liquid-metal reactors (LMRs) received much attention during the 1960s and ’70s when it appeared that their breeding capabilities would soon be needed to supply fissile material to a rapidly expanding nuclear industry. CSTRs (Continuous Stirred Tank Reactor) and PFRs have fundamentally different equations, so the kinetics of the reaction being undertaken will to some extent determine which system should be used. candu reactor Essay Examples. The PWR uses enriched uranium fuel with a slightly higher enrichment level than in a BWR. As you read this module, look back at Figure 11.1 from … More by Peter Priecel. A reactor developed and designed by Canadian is called as CANDU (CANadian Deutorium Uranium ) reactor. Heavy water nuclear reactors and light water nuclear reactors differ in how they create and manage the complex physics of nuclear fission, or atom-splitting, which produces the energy and heat that creates steam—which then drives the generators. CANDU reactors in Canada. For example, since the coolant and moderator are one-and-the-same, relatively cold, dense coolant entering the core will increase moderation, slowing down more neutrons, and cause reactivity to increase. A fast breeder reactor is a small vessel in which the required quantity (correspond­ing to critical mass) of enriched uranium or plutonium is kept without a moderator. Therefore, be careful when you argue for or against thorium reactors. There is minimal pollution, despite the slightly radioactive nature of the element and its unstable nature. Such reactors are … Words. Nuclear Archeology for CANDU Power Reactors. Some of the following points can be valid for one reactor design and another point can be invalid for another thorium-based reactor. The advantage of the high negative temperature coefficient is offset by the fact that it also increases reactor control difficulty. Their performance determines the reliability and suitability of a process, its environmental safety, the energy consumption and the raw materials … Fast Breeder Reactor – Nuclear Power Plant Reactor Such reactors are designed to produce more fissile material (Plutonium) than they consume (Thorium Th-232). Possible Advantages The word CANDU stands for Canadian Deuterium Uranium. CANDU reactor, and shows how the design came about. Disadvantages Reactor Control Issues. Canadian Nuclear Association, 2010. These reactors make use of heavy water, composed of the heavy hydrogen isotope, 1 H 2, as moderator to have maximum neutron economy and as coolant also. Fuel Coolant Arrangement Moderator Fuel Element Pressure Tube Annulus Gas (CO 2) Calandria Tube Coolant Fuel Sheath Individual Fuel Channel. Since the deuterium in heavy water is slightly more effective in slowing down the neutrons from the fission reactions, the uranium fuel needs no enrichment and can be used as mined. A common type of reaction kettle is a horizontal rotary reactor. 24 Jan. 2011. Almost half of CANDU reactors have been built in Argentina, China, India, Pakistan, Romania and South Korea. Core Geometry Subsequent Fission Fuel Original Fission Fuel Thermal Neutron Fast Neutron Moderator.
