History
With 35 years of nuclear power plant engineering experience, Zachry Nuclear Engineering (ZNE) provide expert engineering, design and project management services to support the safe and efficient operation of nuclear power plants. We have completed work for a wide range of nuclear industry clients.

In 1994, the Analysis Group of ZNE released the first version of the PROTO-FLO software tool for piping systems analysis. Since then, the Analysis group has continued to improve and add to the PROTO-Series of software tools for plant analysis with PROTO-HX for heat exchanger performance and PROTO-HVAC for heating, ventilating and air conditioning systems performance.

The ZNE Analysis Division was formed in 2011 with the acquisition of Numerical Applications, Inc. (NAI). Established in 1984, NAI was an industry leader in the development, support and application of software for multiphase flow and heat transfer. NAI’s GOTHIC™ code is used for containment and primary system analysis, building performance (e.g., room heat up, hazardous gas distribution, and fission product release) and to model component systems to address specific to address operating and safety concerns. The software is used in the US and internationally for safety and licensing analysis for Generation 2, 3 and 4 reactor designs, including liquid sodium and molten salt systems.

In 2015, the ZNE Analysis Division range of capabilities and expertise was further advanced by the acquisition of Computer Simulation and Analysis, CSA. Founded in 1988, CSA brought a team of nuclear engineers and computer scientists with extensive expertise in the simulation of reactor core and system thermal hydraulics. Their VIPRE and RETRAN codes are widely used to support existing plants and new system designs for operating and safety analysis. The company was recognized by the US Small Business Administration with a Tibbetts award for innovative and technical accomplishments in the Small Business Innovation Research Program.

The combined expertise of the staff, together with the software tools they have developed for modeling thermal hydraulics and multiphase flow and heat transfer, put the ZNE Analysis Division in a strong position to provided engineering analysis, and software development and support to address the thermal hydraulic issues in nuclear plant design and operation.
