WSC will be making improvements to the GE-Hitachi Nuclear Energy (GEH) BWRX-300 SAE (Simulation Assisted Environment) IPDE (Integrated Plant Design Environment) Engineering Simulator Platform. This BWRX-300 SAE IPDE is based on, and improved from, previous GEH/WSC team experience in development of the ESBWR SAE Mule.

WSC will improve the GEH BWRX-300 SAE IPDE by:

• Adding GE's proprietary Transient Reactor Analysis Code (TRACG), a tool used for analysis of boiling water reactor transients, as the Reactor Thermal-Hydraulic and Neutron Kinetics model inside WSC's 3KEYMASTER environment. The BWRX-300 SAE will include both RELAP5 and TRACG and a means to switch between the two.
• Enhancing the current RELAP5 BWRX-300 model with a 3D kinetics model to replace the current point model, also providing a graphical interface for visualization of the reactor parameters, such as Power Density, Fuel Temperature, Moderator Temperature, Void Fraction, and Rodded Fraction.
• Establishing an enterprise grade BWRX-300 3KEYMASTER SAE IDPE Comprehensive Simulation Platform Cloud-based solution configured for the BWRX-300 SAE simulator. This will also include WSC's cloud-based 3KEYSAFE Configuration Management System and supporting IT environment, needed to set up and use a Cloud-based development environment, to contain all available BWRX-300 design bases generated by WSC in conjunction with, or provided by GEH, with supporting design artifacts.
