CANDU-specific features and advantages Use of natural uranium as a fuel CANDU is the most efficient of all reactors in using uranium: it uses about 15% less uranium than a pressurized water reactor for each megawatt of electricity produced The initial construction costs of nuclear power plants are large. The CANDU 6 reactor design has been chosen as a reference and a brief description of its main components with typical design parameters follows with a comparison with the CANDU 9 reactor. CANDU reactor operators have benefited from several advantages of the CANDU system and from AECL’s experience, with regard to spent fuel handling, storage and disposal. The CANDU design is illustrated in the figure. The heavy water reactor pictured below is used in Canada in CANDU (Canada Deuterium Uranium) type power plant. Advantages Disadvantages The direct cycle simplifies the heat exchange system. One fuel bundle lasts for a year or two. • CANDU fuel is much cheaper than light water reactor ffuel uel • CANDU fuel-manufacturing capability can readily be developed by even small ccountries ountries which purchase CANDU reactors. Nuclear Power-> Nuclear Power Plant-> Types of Reactors-> CANDU - Heavy water reactor. Advantages of the CANDU design CANDU in Europe is recognized for its robustness, having more strong points than any other type of reactor. These reactors are heavy water cooled and moderated pressurized water reactors. – No need for special borated casks • It has few (7) different components. This setup is called a calandria. ... (which leads to a marked preference for the CANDU reactor type due to special features of that type). The chapter includes a note on the advantages of the CANDU reactor compared with One of the advantages of CANDU reactors is that fuel can be continuously changed while the reactor is in operation. CANDU’s ability to utilize unrefined and waste uranium products, coupled with the promise of thorium provides the Canadian reactor design with key advantages. • The CANDU fuel bundle is short and easy to handle. Instead of using a single large reactor vessel as in a PWR or BWR, the … They are also known as CANDU reactors. AECL has over 20 ye0ars experience in development and application of medium-term storage and research and Boiling Water Reactors - Advantages and Disadvantages - Advantages. Nuclear power is one of the few reliable energy sources that can reduce greenhouse gas emissions. Advantages of Nuclear Energy Relatively Low Costs. One of the main advantages of CANDU reactors are that, Nuclear reactors are clean. The EC6 reactor design benefits from the proven principles and characteristics of the CANDU 6 design and decades of operation. The CANDU reactor design (or PHWR – Pressurized Heavy Water Reactor) has been developed since the 1950s in Canada, and more recently also in India. The part of the strategies for nuclear energy to be clean is to is low carbon future. They comprise nearly 1/10 th of all nuclear reactors in the world. The pressure tubes of the fuel element are horizontal and permit refueling while the reactor is in operation. The core of the reactor consists of several fuel channels embedded in a large heavy water moderator tank. Proven CANDU strengths include: Two independent safety shutdown systems CANDU-specific features and advantages Use of natural uranium as a fuel CANDU is the most efficient of all reactors in using uranium: it uses about 15% less uranium than a pressurized water reactor for each megawatt of electricity produced CANDU kills-two-birds-with-one-stone, helping assuage Beijing’s budgetary and pollution-related concerns.
