Application of New In-Core Sensors for CANDU Reactors
Neutron flux detectors are used for a variety of control, monitoring and protection proposes in nuclear reactors. In CANDU(600 MWe class pressurized heavy-water power reactors, for example, in-core self-powered flux detectors (SPFD), manufactured with either vanadium or platinum-clad inconel emittersl, are used for spatial control of the neutron flux distribution and for protection from local over-power excursions, respectively. Although used very successfully in many different applications over many years, the relatively large physical size of self-powered flux detectors, along with their complex dynamic response and small output current, continues to challenge design engineers. An emerging potential alternative to the self-powered flux detectors is the micro-pocket fission detectors (MPFD) 2. These devices are physically small, and exhibit an extremely fast dynamic response, as well as an extremely low sensitively to gamma radiation. As such they appear to be well suited to a variety of in-core neutron flux measurement applications. This paper explores the technical issues of using MPFDs as an in-core neutron flux sensor in a CANDU power reactor.
