Kalsi Engineering Inc. has a team of seasoned engineers with experience at operating nuclear plants in the areas of engineering, operations and maintenance support. The team has plant engineering experience in components, systems, modifications, root-cause analysis, and implementation of Air Operated Valve (AOV) and Motor Operated Valve (MOV) programs. The team has a thorough component/system knowledge and an understanding of plant operations including operational experience by a former Senior Reactor Operator. Component experience includes AOVs, MOVs, check valves, solenoid operated valves, gas-hydraulic actuated valves, valve packing programs, heat exchangers, motors and turbines. The team has been heavily involved in maintenance support of testing, component setup and troubleshooting. Additionally, the team is complemented by engineers with experience in valve manufacturing, valve/actuator sizing, flow modeling and finite element analysis. The Kalsi Engineering team is available to support planned projects as well as the unplanned emergent issues that arise and require timely response.
