Advancement of Instrumentation to Monitor IMSR® Core Temperature and Power Level, Terrestrial Energy USA

The objective of this project is to develop Terrestrial Energy USA’s high temperature gamma thermometer (HTGT) that will accurately determine IMSR® power levels under all normal and off-normal reactor operating conditions. The HTGT will ensure safe and effective control of IMSR® reactor-core power and will be applicable to other MSR designs.

Human Factors Engineering for the Move to Digital Control Systems – Improved Strategies for Operations, GSE Systems

The objective of this project was to develop a simple system that allows control of a plant simulator from a workstation. Called the Task Engine for Job and User Notification (TEJUN, also the Japanese word for “procedure”), the system is a web-based application that allows procedures to be authored in an easy-to-read document format.
