The Economics of the Candu Reactor

1984
The 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.

Thorium as a nuclear fuel for CANDU reactors

The Canadian Journal of Chemical Engineering, 1975
AbstractThe reasons for the attractiveness of thorium as a fuel for CANDU reactors are discussed. By the use of thorium fuels it is shown that the amount of energy that can be extracted from nuclear fuel resources can be increased substantially. Cumulative savings in nuclear fuel requirements are estimated for a number of situations.The thorium fuel ...

Fuel management in CANDU reactors

Annals of Nuclear Energy, 1976
Abstract CANDU fuel management differs completely from that in LWR's. On-power refuelling of the pressurized fuel channels with short (50 cm) fuel bundles is a continuing function of reactor operations and leads rapidly to equilibrium core conditions, refuelling rate, and fuel burn-up.

Transmutation of minor actinides in CANDU reactors

2010 1st International Nuclear & Renewable Energy Conference (INREC), 2010
Large quantities of nuclear waste plutonium have been accumulated in the civilian LWRs and CANDU reactors in form of minor actinides (MAs). Reactor grade plutonium and other transuranium elements can be used as a booster fissile fuel material in form of mixed ThO 2 /MAO 2 fuel in a CANDU fuel bundle in order to assure reactor criticality.

CANDU Reactor Kinetics Benchmark Activity

Nuclear Science and Engineering, 1977
A description of reactor kinetics benchmark activity in support of the Canadian natural-uranium heavy water (CANDU) reactor program is presented. Two benchmark problems with neutronic characteristics resembling current generation CANDU reactors have been defined, and accurate solutions to both problems are summarized. In addition, the performance of an

Proliferation-Resistant Fuel for CANDU Reactors

Nuclear Science and Engineering, 2012
AbstractObtaining denaturated plutonium with 238Pu/Pu ≥ 6% in CANDU reactors can be achieved by introducing either 241Am or 237Np into the nuclear fuel. It was found that about the same results are obtained by doping the fuel with 241Am or 237Np. In order not to reduce the fuel burnup, there is a need to enrich the uranium to 0.8% for both 241Am and ...

Applications to CANDU Reactors

2012
This chapter gives examples of how engineering data of DHC initiation, growth rate, and solvus determinations, supported by theoretical models, and associated underlying property measurements and analyses, are applied in integrity assessments of pressure tubes of CANDU reactors. Examples are given of (1) planar and volumetric flaw assessment approaches

Pressure Tube Development for CANDU Reactors

1984
A development program is described in which reactor grade Zr-2.5Nb pressure tubes were produced with properties comparable to current reactor tubes but which are expected to show lower in-reactor creep and growth. Lower creep and growth rates would mean smaller axial elongations of tubes in service.

CANDU 300: The economic small reactor

Nuclear Engineering and Design, 1988
Abstract The CANDU nuclear power system has evolved in a carefully planned and systematic manner over the past 40 years. Thirty-one CANDU power stations are now in commercial operation, or under construction, world wide. Changes in the demands of the world power market, and growing interest in smaller nuclear units led AECL to develop the CANDU 300,

Moderator heat recovery of CANDU reactors

Journal of Heat Recovery Systems, 1986
Abstract A moderator heat recovery scheme is proposed for CANDU reactors. The proposed circuit utilizes all the moderator heat to the first stages of the plant feedwater heating system. CANDU-600 reactors are considered with moderator heat load varying from 120 to 160 MWth, and moderator outlet temperature (from calandria) varying from 80 to 100°C ...
