Abstract

This paper studies the possibility of adding an experimental channel into the core of the CROCUS nuclear reactor. Thinking about all the implications of the installation of a channel, different configurations for the insertion of a channel are discussed. The reactor is then sim- ulated using the MCNPX 2.4.0 code, in order to compare different possible channels. More precisely, the impact of the channel on the flux distribution, on the energy spectrum, and on the reactivity of the reactor are investigated. Adding a channel have reasonable effect on flux distributions and spectra. The negative reactivity added is reasonable as well, and can be compensated by the addition of a certain number of fuel rods. At the end, we are able to choose the configuration that seems to be the most efficient for an experimental channel.

Research reactor

Research reactors are nuclear fission-based nuclear reactors that serve primarily as a neutron source. They are also called non-power reactors, in contrast to power reactors that are used for electricity production, heat generation, or maritime propulsion. The neutrons produced by a research reactor are used for neutron scattering, non-destructive testing, analysis and testing of materials, production of radioisotopes, research and public outreach and education.

Nuclear reactor

A nuclear reactor is a device used to initiate and control a fission nuclear chain reaction or nuclear fusion reactions. Nuclear reactors are used at nuclear power plants for electricity generation and in nuclear marine propulsion. Heat from nuclear fission is passed to a working fluid (water or gas), which in turn runs through steam turbines. These either drive a ship's propellers or turn electrical generators' shafts. Nuclear generated steam in principle can be used for industrial process heat or for district heating.

Breeder reactor

A breeder reactor is a nuclear reactor that generates more fissile material than it consumes. These reactors can be fuelled with more commonly available isotopes of uranium and thorium, such as uranium-238 or thorium-232, as opposed to the rare uranium-235 which is used in conventional reactors. These materials are called fertile materials since they can be bred into fuel by these breeder reactors. Breeder reactors achieve this because their neutron economy is high enough to create more fissile fuel than they use.
