Triconex nuclear power plant customer receives award for technology transfer

IRVINE, Calif., Aug. 6, 2002 — Triconex, an operating unit of Invensys plc, recently announced that its customer Florida Power has received a “technology transfer” award from the Electric Power Research Institute (EPRI) for the first U.S. installation of a Triconex Unit Load Demand System.

Florida Power, a Progress Energy company, installed the system at its Crystal River nuclear power plant located in Crystal River, Florida. The Triconex system, the first of its kind to be installed in a domestic nuclear power plant, fully automates the plant’s power level control function.

“This new, pre-qualified system allows us to safely operate the plant closer to its licensed thermal limit,” said Mike Lord, Florida Power senior nuclear instrumentation and control engineer. “It reduces operator burden and allows for a phased conversion of analog to digital control technology.”

The federal Nuclear Regulatory Commission (NRC) issued a safety evaluation report earlier this year certifying Tricon version 9, and all associated hardware and software, for use in 1E Safety Critical applications in nuclear power plant instrument and control systems. Tricon is the first triple-modular redundant technology to receive NRC approval.

“Florida Power’s successful adoption of Triconex triple-modular redundancy technology is a significant milestone for the nuclear industry,” said Tracey Sledge, Triconex general manager. “With more than 4,000 Tricon systems in use in industrial control applications around the world and more than 140 million safe operating hours, we are confident Triconex technology can improve performance and reliability at operating nuclear plants worldwide.”
