GSE Systems Completes Simulator Upgrade at Bruce Power Nuclear Plant - Will Provide Improved Operator Training

SYKESVILLE, Md. – Global energy services solutions provider GSE Systems, Inc. (NYSE MKT: GVP) ("GSE") was chosen by Bruce Power, Canada's first private nuclear generator, to upgrade the simulators for units 2 and 3 of the company's Bruce A generating station. The upgrade provides new high-fidelity predictive models that enable more realistic and dynamic training for plant operators and new instructors.

During the project, GSE:

Replaced the primary heat transport and boiler systems with RELAP5-HD™ real-time thermohydraulic solution to provide accurate results for all modes of plant operation.

Replaced the reactor core model with GSE's REMARK™ real-time multi-group reactor simulation.

Replaced a sub-channel thermohydraulic model with GSE's JTopmeret™ two-phase fluid modeling tool for each fuel bundle to achieve proper reactivity feedback.

Replaced the calandria, maintenance cooling, feed and bleed, main feedwater, PHT pump seals and annular gas systems with JTopmeret.

Integrated its SimExec™ simulation platform with the Western Services 3KEYMASTER platform to improve how Bruce Power authors its own simulation system.

In addition, GSE performed on-site pre-tests and final tests, which included startup, shutdown, transients, malfunctions and emergency tests. GSE also supported Bruce Power in preparing the training scenarios.

"GSE's new models overcame technical deficiencies that existed in the simulators before the upgrades," said Cynthia Mercanti, Section Manager Simulator Support for Bruce Power. "The new simulators enable our operators to train in new scenarios that did not exist prior to the upgrade."

"This project marks GSE's first CANDU (CANada Deuterium Uranium) reactor simulator upgrade, and was delivered successfully on time, on budget and on spec," said Mahmoud Nazem, Project Manager for GSE. "This shows that GSE has the right technology and resources to simulate complex systems such as CANDU-type plants."
