The Canadian pressurised heavy water reactor (PHWR) is unique among the major nuclear reactor types for several reasons, but in particular because Canada is the only country in the world which has developed and adhered to a single reactor system to meet a specific national ...

Properties of a Candu Calandria Tube
Canadian Metallurgical Quarterly, 1985AbstractWe have destructively examined the Zircaloy-2 calandria tube which surrounded a pressure tube that ruptured in Pickering Unit 2 Nuclear Generating Station. The calandria tube was in excellent condition and had sustained little damage. The material was hardened by neutron irradiation.

The Economics of the Candu Reactor
1984The purpose of this chapter is to: 1. Discuss the cost of producing electricity from CANDU-Pressurized Heavy Water (PHW) nuclear generating units. 2. Present actual cost experience of CANDU units in Ontario Hvdro. 3. Compare CANDU cost experience with fossil (coal) experience in Ontario Hydro. 4.

Advanced technologies for CANDU reactors
Nuclear Engineering and Design, 1993Abstract The inherent features of a reactor based on multiple pressure tubes, rather than a single pressure vessel, provide CANDU with considerable flexibility for continuous design improvements. Of particular significance is the presence of a large volume of cool heavy-water moderator within the core.

Excellent neutron economy and on-line refuelling allow CANDU reactors to operate on a variety of fuel cycles. Atomic Energy of Canada Limited (AECL) has an on-going program exploring fuel options [1,2]. The motivation includes fissile resource extension, fuel cycle economics, and waste management, environmental, political and strategic considerations ...

Basics of CANDU Reactor Physics
2021Nuclear fission is the splitting of a (large) nucleus, with the release of energy. The nuclei of some heavy elements, such as U-238, do exhibit spontaneous fission in nature. However, the rate of such fissions is extremely low. The half-life of uranium is longer than 100 million years, and most of its decay is by alpha emission, so spontaneous fission ...

TEPC Performance in the CANDU Workplace
Radiation Protection Dosimetry, 1997Tissue-equivalent proportional counters (TEPCs) have a number of features that make them an attractive option for neutron monitoring around power reactors. These features are principally the ability of the TEPC to operate in a mixed field environment, the direct determination of the dose equivalent from first principles and a reasonably well-understood

Degraded Cooling in a CANDU Reactor
Nuclear Science and Engineering, 1984Loss of coolant accident (LOCA) analysis for a Canada Deuterium Uranium (CANDU) reactor considers a wide range of postulated break sizes and locations in the heat transport piping. Coincident failure of the emergency coolant injection system to operate on demand must also be considered.

The ndt requirements for CANDU
Non-Destructive Testing, 1974Abstract The author describes some of the testing problems posed by the CANDU nuclear reactor system. CANDU uses heavy water as moderator and coolant and uses pressure tubes rather than a pressure vessel. It has much in common with the British steam generating heavy water reactor.
