Further Callaway work for L-3 MAPPS

Monday, 7 June 2010

L-3 MAPPS has received two orders from US utility AmerenUE to support the upgrade of the integrated control system (ICS) of its Callaway nuclear power plant in Missouri. Last year the company was awarded a contract to upgrade the plant's simulator.

The Siemens SPPA-T3000 ICS will be installed to support the feedwater system at Callaway during the plant's next refuelling outage in the autumn of 2011. The upgrade of the feedwater control system is part of an effort to integrate multiple control systems. Other analogue controls will also be replaced with the T3000 following the feedwater system upgrade.

 

Under the first order, L-3 MAPPS will simulate the instrumentation and control (I&C) system and corresponding human-machine interface and integrate it with the plant model that is currently being updated. The company will provide a tool for the simulated ICS that will import I&C functional diagrams into its Orchid modelling environment, automatically creating a simulation of the I&C. The tool will facilitate incorporation of future ICS modifications and upgrades to the simulator.

 

For the second order, L-3 MAPPS will design and develop a test system that will be used to connect the Callaway plant simulator directly to the plant's ICS as part of testing prior to final installation. The ICS test system is scheduled for delivery to the Callaway plant in the summer of 2010. The updated simulator, incorporating the simulated ICS, is scheduled to be operational in early 2011. When operational, the simulator will allow Callaway operators to train on the new ICS before the system is utilized for actual plant operations.

 

In a statement, L-3 MAPPS said that it welcomed the opportunity "to build up our experience with the SPPA-T3000, which will certainly play an important role in new nuclear builds."

 

In February 2009, L-3 MAPPS was awarded a contract by AmerenUE to upgrade the simulator at the Callaway plant with a new suite of software tools, having upgraded the plant's core model in 2008. Under the upgrade, legacy simulator modules that have been in use since the 1235 MWe pressurized water reactor began operation in 1984 will be replaced by new ones.
