Grand Gulf has used AMS-4s with telemetry capability to monitor open roof hatches. Telemetry is monitored in the Control Room with a set point that requires closing the hatch. We have never hit the setpoint, but have had to close the hatches for weather.
Fred Rosser From: [email protected] [mailto:[email protected]] On Behalf Of Thomas J Vandermey Sent: Friday, August 09, 2013 10:40 AM To: [email protected] Subject: Powernet: gaseous effluent monitoring and control During an upcoming 3 week plant outage, Fermi wants to shut down all turbine building ventilation for repairs, with roof vents open for cooling. Prior to this outage, it appears there will have been no detectable turbine building gaseous effluents (except tritium) for several months. No turbine building work which would increase effluents is planned for the outage. What controls would you suggest for this evolution?
