Title: Assembly and characterization of fast neutron detectors for TREAT fuel motion monitoring system

Abstract

The TREAT fuel motion monitoring system (FMMS) currently uses a fast neutron hodoscope which allows for fast neutron imaging produced by fission in the reactor core. These neutrons are then passed unmoderated through a core slot and collimated to the 360 detector array, or hodoscope. The purpose of this project was to assemble, characterize, and qualify another 96 PMT’s to add to the current batch of 96. The assembly consists of four main components starting with a PMT, a voltage divider, a PRS button that will scintillate when struck by neutrons, and a Phenolic shroud which will house all the components to create a standard form factor. The characterization will be completed in the lab to reach the goal of having all PMT’s characterized with a determination of operability before finalized and placed inside the TREAT hodoscope.
