Thermal Hydraulic Engineering and Safety Analyses

The Westinghouse Solution

The Westinghouse BOP and Design Engineering Thermal-Hydraulic Engineering and Safety Analyses team is comprised of specialists with extensive technical and licensing background covering the disciplines of heat transfer, fluid flow, nuclear engineering, and mechanical engineering. Most of the engineers have over 30 years of experience in the nuclear power industry and were part of the Balance-of-Plant (BOP) Architect Engineering (AE) teams that were responsible for putting numerous nuclear power plants online. Currently, the team provides support to both advanced reactor designs as well as the fleet of operating nuclear power plants.
