The TREAT Upgrade Manual Reactor Control System and Its Interface with the Automatic Reactor Control System and the Plant Protection System

The Transient Reactor Test Facility (TREAT) at Argonne National Laboratory is being upgraded to to simulate extreme conditions in a reactor. This facility will be used to subject test assemblies of fuel bundles to very rapid and intense power transients. This paper will describe in detail the manual reactor control system and its interfaces with the plant protection system the automatic reactor control system.
