A Channel for Neutron Flux Measurement

Instruments and Experimental Techniques, 2002
The design principles of a channel for measuring fluxes of thermal neutrons in a nuclear-reactor control and protection system are considered. The channel consists of a fission chamber, a set of boron-containing gas-filled ionization chambers, and an electronic unit that ensures a counting rate of fission pulses of up to ∼1 × 106 s–1.

Neutron flux measurement channel utilizing the Campbell technique / Neutronenflußdichtemeßkanal mit Nutzung des Campbell Verfahrens

Kerntechnik, 1999
The Campbell technique for the neutron flux measurement was investigated. This technique utilises the AC component (noise) of a neutron chamber signal rather then DC component, which is usually used. The Campbell theorem explains that the root mean square of the AC component of the chamber signal is proportional to the neutron flux (reactor power ...

Measurement of neutron flux distribution in the irradiation channel in the Ghana Research Reactor-1 using Monte Carlo method

Progress in Nuclear Energy, 2011
Abstract The Monte Carlo method was used to determine the neutron fluxes in the irradiation channels of the Ghana Research Reactor-1. The MCNP5 code was used for this purpose to simulate the radial and axial distribution of the neutron fluxes within all the 10 irradiation channels.
