Improved cable compensation technique for self powered neutron detectors

Nuclear Instruments and Methods in Physics Research Section A: Accelerators, Spectrometers, Detectors and Associated Equipment, 1996
Abstract Measurements with cobalt self powered neutron detectors on the BR2 reactor have revealed that the currents induced by external gamma radiation can be of the same order as the neutron induced signal and that the gamma induced current on the emitter and the compensator wires are not symmetric.

A Monte-Carlo Calculation of the Neutron Sensitivity of Self-Powered Detectors

IEEE Transactions on Nuclear Science, 1973
Self-powered (s-p) detectors are useful for incore neutron measurements in nuclear reactors because of their small size, ruggedness and simplicity. In one type of detector, a delayed current results from the beta activity induced in the device by the neutron flux while a second type gives an instantaneous response due to the compton electrons produced ...

A Study on the Burnup Effect of Silver Self-Powered Neutron Detector

Volume 3: I&C, Digital Control, and Influence of Human Factors
Abstract Self-Powered Neutron Detector (SPND) has been widely used in reactor core for in-core neutron flux monitoring. As a typical delayed type of SPND, the burnup behavior of Ag SPND is more complicated than Rh SPND and VSPND, because Ag is composed of two natural isotopes 107Ag (51.839%) and 109Ag (48.161%) with distinct neutron ...

Electron Spectral Contribution of Prompt-Response Self-Powered Neutron Detectors

1989
In the present work we use a new model for calculating the effective charge induced per neutron capture in a prompt-response Self-Powered Neutron Detector (SPND). This charge is written as the integral over all possible energies of the spectral function S(E) weighted with the electron spectral contribution ∑(E).

Effect of Fission Betas, Activated Structures and Hydrogen on Self Powered Neutron Detectors

IEEE Transactions on Nuclear Science, 2013
It is shown that when vanadium Self Powered Neutron Detectors are placed too close to fuel rods, fission betas can cause a significant perturbation of the signal. It is shown that this effect can be used to measure the decrease of the fuel rod power over time due to the burn-up.
