WSC — Nuclear Power Plant Simulation

Complete spectrum of nuclear simulation services

WSC works closely with its customers to provide high-quality, cost-effective simulation solutions — from full-scope training simulators to engineering-grade models — applicable to any plant in operation, under construction, or in design.

Simulation Platform

3KEYMASTER™ — The Foundation

The first simulation environment ever developed from the ground-up using an object-oriented approach to process modeling, 3KEYMASTER™ serves as the core platform for all WSC nuclear simulation solutions.

WSC maintains partnering arrangements with I/O, panel, and computer system vendors to offer each customer their optimal solution. The 3KEYSAFE™ configuration management system provides an environment for conserving and tracking all plant data through the full lifetime of the simulator.
