Nuclear Power

Unparalleled expertise in nuclear power flow control

IMI Critical Engineering brings over 60 years of experience in the nuclear industry to the table. Our expertise is relied upon to prevent and address issues related to legacy valves in nuclear power plants.

Our engineered chokes excel in high well head pressures, aggressive fluids, entrained solids, and velocity control

Enhancing reliability

As the nuclear power industry seeks to extend the lifespan of older reactors, including boiling water reactors (BWR), pressurised water reactors (PWR), and pressurised heavy water reactors (PHWR) designs, they face specific challenges related to legacy valves. These valves can present problems that hinder the safe and efficient operation of nuclear power plants.

At IMI Critical we understand the critical importance of ensuring the reliability and safety of these systems.

The state-of-the-art IMI Critical site in Korea ensures valve performance by meticulously spraying valves before testing, ensuring reliability and longevity.

Overcoming challenges through innovation

With a focus on innovation, we have developed and rigorously tested advanced valve technologies that meet the stringent requirements of both new construction, and next-generation nuclear power stations, including Small Modular Reactors (SMRs). These cutting-edge solutions are designed to optimise performance, enhance safety, and improve efficiency in the nuclear industry.

By addressing legacy valve challenges and advancing nuclear power technologies, we contribute to a sustainable future for all, ensuring energy security and reducing greenhouse gas emissions.

Our Valve Doctors™ are IMI Critical’s top technical experts who can help our customers solve the most demanding engineering challenges.
