Testing of the Y-12 Plant Criticality Accident Alarm System Detectors at the Sandia Pulsed Reactor Facility
- Oak Ridge Y-12 Plant (Y-12), Oak Ridge, TN (United States)
- Sandia National Labs., Albuquerque, NM (United States)
The Oak Ridge Y-12 Plant operates its Criticality Accident Alarm System (CAAS) according to the guidance of Standard ANSI/ANS-8.3-1986. This standard requires that the detector shall not fail to initiate an alarm when subjected to a radiation field of at least 0.1 Gy/s (10 rad/s). It also requires that the system shall be designed to immediately detect the minimum accident of concern and shall produce an alarm within one half second of activation. Sixty-three new detectors that use plastic scintillators have been obtained to upgrade the current Y-12 Plant CAAS. To ensure that these detectors can support the above criteria, testing was done using the SPR III reactor at the Sandia Pulsed Reactor Facility.
