The Transient Reactor Test (TREAT) facility recently replaced the automatic reactor control system (ARCS). This paper discusses some of the enhancements that were made during the ARCS replacement such as calculations to take into account the nonadiabatic effects and increasing the dynamic range for power and period indication. This paper also discusses upgrades that had been planned but were unable to implemented and potential upgrades for the future.
