In the US, GSE will provide its updated simulation environment and modeling software for nine simulators and its electrical system models for seven simulators owned by one of the country’s nuclear utilities. GSE’s modeling tools are the standard for this utility’s fleet of simulators and will be used for future simulator upgrades.

In Europe, the company will modify five existing simulators that will allow them to run modern computer operating systems and employ the company’s simulation tools.

Under a separate contract, the company will deliver its RELAP5-HD model and simulation tools for the Kozloduy simulator in Bulgaria. This brings the number of RELAP5-HD projects to eight and continues the trend of customers improving the realism of their simulators by using GSE’s RELAP5-HD technology for the reactor thermal hydraulic systems, the company said.

John Moran, CEO of GSE, said: “Servicing, modifying and upgrading the world’s fleet of existing nuclear plant simulators continues to be a major revenue stream for GSE. This work is driven by the global movement to extend the life of existing nuclear plants, uprating plant power generation levels and making modifications to older simulators to allow the latest generation of simulation technology to be deployed.

“Three of the contracts announced today are from existing GSE customers, two of whom own multiple GSE simulators and look to standardize their simulation technology as much as possible. The remainder of the contracts are with new customers who are looking for industry leading service and simulation solutions. GSE’s electrical system modeling capability has set the standard for the domestic market and our state of the art RELAP5-HD solution continues to gain market share both domestically and abroad.”
