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

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 ...
