Analysis of vanadium Self Powered Neutron Detector’s signal

Annals of Nuclear Energy, 2013
Abstract Self Powered Neutron Detectors (SPNDs) have been widely used for monitoring the neutron flux, either in Nuclear Power Plants (NPPs) as well as in irradiation facilities and medical treatments. Nevertheless, the physical meaning of the parameter used to relate the detector signal (an electric current) to the neutron flux, i.e. , the detector

Characterization of hybrid self-powered neutron detector under neutron irradiation

Fusion Engineering and Design, 2000
Abstract To evaluate the irradiation behaviour of a blanket mock-up on in-pile functional test, it is necessary to measure the neutron flux change in the in-pile mock-up by a neutron detector, such as the self-powered neutron detector (SPND). With its small-sized emitter, which has high sensitivity and fast response time, SPND is an indispensable ...

Numerical optimization of Rhodium Self-Powered Neutron Detector

Annals of Nuclear Energy, 2018
Abstract Self-Powered Neutron Detector (SPND) has been widely used in reactors to monitor neutron flux due to its adaptability for in-core severe environment. As a typical representative, SPND with Rhodium as its emitter has been modeled in the frame of Geant4, which is good at tracing the history of the particles in simulation and very appropriate ...

Development and verification of a simulation toolkit for Self-Powered Neutron Detector

Annals of Nuclear Energy, 2021
Abstract A response simulation toolkit ‘SPNDSignal’ based on Geant4 was developed and verified. SPNDSignal adopts Monte-Carlo method to simulate the coupled neutron-gamma-electron transportation in SPND, and the important physical parameters such as neutron sensitivity and current components can be obtained.

Deconvolution-based real-time neutron flux reconstruction for Self-Powered Neutron Detector

Nuclear Engineering and Design, 2018
Abstract Self-Powered Neutron Detector (SPND) is useful for in-core neutron flux measurement in nuclear reactors due to its tiny size, simple structure, ruggedness and self-powered feature. One type of SPNDs with delayed current from instable intermediate nuclides cannot directly represent the real-time in-core neutron flux Φ(t) by their current I(t),

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 ...
