Investigation of CANDU reactors as a thorium burner
Energy Conversion and Management, 2006Abstract Large quantities of plutonium have been accumulated in the nuclear waste of civilian LWRs and CANDU reactors. Reactor grade plutonium can be used as a booster fissile fuel material in the form of mixed ThO2/PuO2 fuel in a CANDU fuel bundle in order to assure reactor criticality.

The CANDU Reactor System: An Appropriate Technology
Science, 1978CANDU power reactors are characterized by the combination of heavy water as moderator and pressure tubes to contain the fuel and coolant. Their excellent neutron economy provides the simplicity and low costs of once-through natural-uranium fueling. Future benefits include the prospect of a near-breeder thorium fuel cycle to provide security of fuel ...

Utilization of TRISO fuel with reactor grade plutonium in CANDU reactors
Nuclear Engineering and Design, 2010Abstract Large quantities of plutonium have been accumulated in the nuclear waste of civilian LWRs and CANDU reactors. Reactor grade plutonium and heavy water moderator can give a good combination with respect to neutron economy. On the other hand, TRISO type fuel can withstand very high fuel burn-up levels.

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 ...

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.

CANDU Reactor Kinetics Benchmark Activity
Nuclear Science and Engineering, 1977A 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, 2012AbstractObtaining 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 ...

CANDU reactors with reactor grade plutonium/thorium carbide fuel
Kerntechnik, 2011Abstract Reactor grade (RG) plutonium, accumulated as nuclear waste of commercial reactors can be re-utilized in CANDU reactors. TRISO type fuel can withstand very high fuel burn ups. On the other hand, carbide fuel would have higher neutronic and thermal performance than oxide fuel.

Fuel management in CANDU reactors
Annals of Nuclear Energy, 1976Abstract 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.
