Review of Irradiation Programs to Study Long-Term Behaviour of In-Core Components in CANDU Reactors

Journal of Nuclear Engineering
During the life of a nuclear reactor, there are changes to the in-core components that are a function of operating environment and time. It is important to know how the properties of critical core components change, which can be assessed through ...

Dynamic Xenon Response in a CANDU-600 Reactor: A Simulation Study of Power Variations

Annals of West University of Timisoara: Physics
This paper presents a comparative simulation study of xenon and fission product behavior in a CANDU-600 reactor core operating at nominal full power (100%) and an aging CANDU-600 core limited to 90% power due to end-of-life constraints.
