These accomplishments include the completion of the refurbished plant models for the legacy Koeberg operator training simulator and putting into service a second full scope simulator at the site on 1 August 2013.
The company carried out the refurbishment activities in two phases. Under Phase 1, which enabled Koeberg to pre-train its operators for plant changes that followed in late 2010, the company provided Orchid simulation platform and remodeled the balance of plant process loop.
The first phase also included simulation of the new Alstom Alspa Controsteam steam turbine controller, emulation of the core monitoring system display and provision of an interface to Westinghouse’s Ovation DCS, the company said.
The remaining plant models are refurbished under Phase 2 that included containment, emergency core cooling, electrical systems and common services in L-3’s Orchid Modeling Environment. Additionally, the company has moved the legacy control logic into the Orchid Modeling Environment through a translator under the second phase, according to the company.
The second accomplishment was putting into service the second full scope simulator, which involved replicating the plant’s main control room and emergency control facility driven by a compact modular input/output (I/O) system using Wago-I/O-System 750 hardware and L-3’s Orchid Input Output software.
L-3 MAPPS has connected the new Orchid simulation platform and upgraded models with the new second simulator’s hardware to provide validation to Eskom.
L-3 MAPPS Power Systems and Simulation vice president of marketing and sales Michael Chatlani said that having accomplished two projects at Koeberg, L-3 MAPPS intends to provide a continued support to Eskom in the future.
"Following the putting into service of the Embalse full scope simulator in Argentina earlier this year, the Koeberg simulator deliveries in South Africa once again demonstrate that L-3 MAPPS is the world’s leading nuclear power plant simulation solution provider," added Chatlani.
