L-3 MAPPS to upgrade Angra 2 simulator

7 August 2009

L-3 MAPPS has signed an agreement with Eletrobras Termonuclear S/A to upgrade the simulator for Angra 2 in Brazil. The project is due to begin this summer will last for about two years.

The first phase of the project will see the simulator’s software rehosted to PC/Windows-based computers running L-3 MAPPS’ modern Orchid simulation environment with advanced instructor station capabilities. The legacy models currently programmed in assembly language will be converted to C language. The ageing master controller will be replaced, and L-3 MAPPS will implement a new master controller to establish I/O communications with the hard panels.

As a second step, the primary system models will be replaced with higher fidelity models. L-3 MAPPS will supply its advanced neutronics model generated by Orchid Core Builder to replace the reactor core model, and use Orchid Modeling Environment to provide the nuclear steam supply system, containment, and HVAC models.

Angra 2, a 1350MWe Siemens-designed pressurised water reactor, was connected to the grid in 2000. It is located near the town of Angra dos Reis, roughly 200 km south of Rio de Janeiro.The Angra 2 simulator is located at Eletronuclear’s training centre in Mambucaba.

Commenting on the contract, Michael Chatlani, vice president of marketing & sales for L-3 MAPPS Power Systems and Simulation said: “L-3 MAPPS is pleased to be involved with the Angra 2 simulator. We look forward to continuing our expansion in South America."
