Neutron sensitivity of vanadium self powered neutron detectors

Nuclear Instruments and Methods in Physics Research Section A: Accelerators, Spectrometers, Detectors and Associated Equipment, 1986
Abstract The neutron sensitivity of vanadium self powered neutron detectors (Type 5503-B), manufactured by Studsvik, Sweden, has been measured. Using the calculational model developed by Warren, the neutron sensitivity of these detectors has been computed taking into account additional factors viz.

A study on the sensitivity of self-powered neutron detectors (SPNDs)

IEEE Transactions on Nuclear Science, 2001
Self-powered neutron detectors (SPNDs) are widely used in reactors to monitor neutron flux, while they have several advantages such as small size, and relatively simple electronics required in conjunction with those usages, they have some intrinsic problems of the low level of output current-a slow response time and the rapid change of sensitivity-that

Layout Optimization of Self-Powered Neutron Detector for HPR1000

Volume 15: Student Paper Competition, 2022
Abstract Self-Powered Neutron Detector (SPND) has been widely applied for the on-line monitoring of the key core parameters, including the power distribution, power-peak factor and so on. For the SPND layout design, the vital parameters include the SPND amount and loading position in the radial direction and segment amount in the axial ...

Transient response of self-powered neutron detectors

Nuclear Instruments and Methods, 1975
Abstract The behaviour of self-powered neutron detectors with Co, Er, Hf and Pt emitters was investigated during reactor square wave and pulse operation. The detector's response was compared with the current of an excore ionization chamber. Characteristical deviations from linearity were observed with all detectors at fast reactor periods.

Differential sensitivity of long self-powered neutron detectors

Nuclear Instruments and Methods, 1970
Abstract Measurements of the differential sensitivity of two 3.3 m long rhodium detectors are presented. The detectors are to be used in connection with an experiment in the Oskarshamn I reactor for integration of the thermal neutron flux over the full fuel length.

A novel solid state self-powered neutron detector

SPIE Proceedings, 2008
Detection of nuclear materials is critical in preventing traffic of illicit nuclear materials. Several methods that are based on detection of spontaneous or induced emission of fission neutron are considered. Efficient fast and thermal neutron detectors are generally required.

Dynamic Compensation of Rhodium Self Powered Neutron Detectors

IEEE Transactions on Nuclear Science, 1976
A mathematical model of a rhodium self-powered neutron detector has been developed to investigate the detector transfer function and to apply this transfer function as compensation for the inherent time delay in the rhodium-neutron interaction. The various reactions that comprise the detector signal have been evaluated experimentally and the resultant ...

Self-Powered Neutron Detectors for Measuring Epithermal Neutron Flux

1989
Self-powered neutron detectors (SPNDs) with erbium, hafnium, gadolinium, rhodium, silver, and cobalt emitters have been irradiated in several different neutron and gamma spectra obtained by a variety of filters: cadmium, gadolinium, boron, lead, zirconium, aluminum, or light water.
