A MICROPROCESSOR-CONTROLLED TESTER FOR EVALUATION OF THE SELF-ENERGIZED
CREDENTIAL SYSTEM (SECS)
The Self-Energized Credential System (SECS) was
developed for use in the Plutonium Protection System
(PPS) installed at Hanford, Washington. Evaluation
and development of the SECS system was enhanced by the
use of a microprocessor-controlled portal tester.
This tester used infrared (IR) beam sensors to provide
information on the. direction of travel of the cre-
dential wearer and to detect inoperative credentials.
A printed record of the portal number, actual code
read, time, and direction of the credential passage
provided information essential to an assessment of the
operability of the SECS.
