Abstract
An improved alarm system to detect and warn against uncontrolled nuclear criticality events has been developed for the Hanford site. The system is neutron sensitive with an alarm threshold of 8 millirad/hour of "steady" neutron irradiation or 4 microrad of pulsed radiation. Redundancy techniques and self-check features have been incorporated whenever possible to enhance operational reliability.
