Development of a Limited Angle Gamma Ray Emission Tomography System for In-Situ Spatially-Resolved Measurement of Fuel Burn Up and Pre-Shutdown Power

摘要

LATIMER is the first SPECT laminograph designed for spatially-resolved, in-situ measurement of fuel burn up and pre-shutdown power. The basic system design has been completed and the size and shape of the vertical collimator is being optimized through Attila modelling. Once this step is complete, manufacture and build will commence. As the data acquisition, post-processing and reconstruction software is common to the EGRET system developed previously by the Defence Academy of the United Kingdom, it is expected that testing will commence in summer 2018. Investigations into whether LATIMER can be used whilst the reactor is at power will be undertaken in the near future.
