Calculation of the signal current of self-powered neutron detectors in a nuclear reactor

He jishu
BackgroundSelf-powered neutron detectors (SPNDs) are critical devices in the monitoring and protection systems of nuclear reactors, and their signal current directly reflects the value and distribution of the core power. Insulators play an essential role

Assessment of SPND Signal in IFMIF-DONES using a Monte Carlo Modelling

Journal of Fusion Energy
IFMIF-DONES (International Fusion Materials Irradiation Facility-DEMO Oriented Neutron Source) is a key facility for the study and analysis of the materials properties exposed to irradiation conditions characterised by a high neutron flux with high energies up to 55 MeV. These irradiation conditions are expected by the future DEMOnstration fusion power

Response of the SPND measurement system to temperature during the Three Mile Island Unit 2 accident. [Self-Powered Neutron Detector] [PDF]

, 1981
The Self-Powered Neutron Detector (SPND) Measuring System is evaluated to determine its ability to indicate temperatures of the fuel rods in the TMI-2 reactor core during the accident. It is concluded for the following reasons that the SPND Measuring System did not provide fuel rod temperatures during the accident: the heat transfer characteristics ...

Thermal neutron flux measurement using self-powered neutron detector (SPND) at out-core locations of TRIGA PUSPATI Reactor (RTP)

IOP Conference Series: Materials Science and Engineering, 2018
The thermal neutron flux measurement has been conducted at the out-core location using self-powered neutron detectors (SPNDs). This work represents the first attempt to study SPNDs as neutron flux sensor for developing the fault detection system (FDS) focusing on neutron flux parameters.
