L-3 Mapps to upgrade simulator at nuclear power plant in Switzerland

L-3 Mapps will proceed with two projects to update the full scope simulator at Axpo’s 730 MWe Beznau nuclear power plant in Switzerland.

The projects involve Nexis and Autanove updates being performed on the plant’s two operating units. The simulator updates are expected to enter service in the fall of 2013.

As part of the Nexis project, the plant is replacing its existing WDPF-based plant information system with an advanced Ovation-based system from Westinghouse. L-3 Mapps will modify the interface to the existing plant information system to allow communication with the Ovation system.

For the Autanove project, the existing remote hydro plant emergency power supply is being replaced with two on-site diesel generators for each unit. L-3 Mapps will leverage its Orchid Modeling Environment to remodel the electrical emergency power supply, including power distribution. The new diesel generators will be fully simulated with their auxiliary and control systems. The updated simulator must be operational before the plant modifications go into service in order to train the plant operators.

Other related plant changes that will be modeled are the addition of a feeding system to the emergency feedwater system and a seal water pump to the seal injection water supply to the reactor coolant pump, each controlled by Areva’s Teleperm XS.
