Nearly a decade of work to consolidate six control rooms into a single facility at the Savannah River Site tank farms is nearing completion with the recent closure of two F Tank Farm control rooms.

Signing off the command and control functions of the 1F and 74F control rooms last month marked the end to more than 50 years of service. This brought the number of control rooms remaining for consolidation to one.

The control room consolidation project that began in 2005, is designed to centralize an operator’s control functions to a single control room in the H Tank Farm. The consolidation efforts have been extensive, according to Savannah River Remediation control room consolidation project manager Ricky Doniphan.

“Considerable work has been completed to this point including design and software changes, installation of new equipment and miles of fiber optic highway, and thousands of wiring changes in the field,” Doniphan said. “Plus, we have had extensive startup testing, operator and support training, consolidation of the emergency preparedness program and well over 1,000 procedure changes. The work has been huge, but the team has contributed to the safe execution of the project.”

Control room consolidation activities began with the closing of four control rooms and a waste transfer diversion box. The final control room, 18F, located in F Tank Farm, will be closed later this year.
