Y-12 technology gets development boost


Two devices that delay passage to controlled-access areas at Y-12 recently received significant developmental boosts. The Access Rate Control System (ARCS) and the Delayed Latching Mechanism (DLM) were licensed in February by Knoxville start-up Sustainable Environment Technologies, LLC (SET). About five weeks later, Y-12 and the licensee signed a Cooperative Research and Development Agreement (CRADA).

The ARCS is a kit designed for installation on existing or new full-height turnstiles. It generates resistance and slows entry if someone enters at faster-than-normal speed. The DLM slows unlatching of gates and doors from the outside, requiring a sequence of actions to retract the latch and giving security personnel time to prevent the door or gate from opening if necessary.

Y-12 President and General Manager Darrel Kohlhorst voiced support to SET President Dan Hurst, said, “Once we know that something we have invented works, we want to make it possible for someone else to use it. It’s our job not only to facilitate a license but also to work with the licensee to get it off the ground. If we are using these devices, there is no reason they are not at every one of the NNSA sites.”

Anticipated markets include other U.S. Department of Energy facilities, commercial nuclear facilities, pharmaceutical manufacturers, correctional facilities, and large sporting venues. Both devices were invented by senior technical advisor and National Security Technology Center director Lee Bzorgi, whom Popular Science magazine has called “DOE’s Gadget Guru” because of his numerous inventions.
