20 Years of Reliable High-Pressure Steam for Nuclear Pump Testing in Glasgow

Project Overview

For over two decades, a specialized test facility in Glasgow has relied on three Clayton E-604 steam generators, to deliver consistent, high-performance steam for nuclear-grade pump testing.

These units, each rated at 6 MW and designed to operate at 100 barg, form the heart of a demanding test environment where precision, safety, and reliability are paramount.

More information

Application

The plant’s primary function is to test steam-driven pumps used in nuclear applications. During full-load tests, the system delivers approximately 25 tons of steam per hour at 100 barg pressure, simulating real operational conditions.
Each test involves starting, stopping, and restarting the pumps at full output within seconds. These extreme load transitions place exceptional demands on both the pumps and the steam generation system.

Why Clayton

For this project, dry steam was essential to prevent damage to the steam turbine side of the pump. The Clayton steam generator’s unique design ensures steam of exceptionally high dryness and purity, making it ideal for sensitive turbine-driven systems.

Beyond steam quality, the Clayton coil design and forced circulation principle deliver unmatched flexibility, allowing the system to handle rapid load changes and pressure fluctuations without compromising safety or performance.
In addition, the Clayton units can be kept in cold stand-by between tests, consuming no energy when idle, a crucial benefit since the pumps are tested only a few times per month.

Performance and Efficiency

Even after more than 20 years of operation, the three E-604 units continue to perform reliably and efficiently. The system can go from stand-by to full 100 barg operation in under 20 minutes, providing instant readiness and minimal energy waste.
This responsiveness and durability make the installation one of the most efficient high-pressure test facilities of its kind.

Results

20 years of continuous operation with exceptional reliability
High-quality dry steam to protect sensitive turbine components
Rapid start-up: from cold stand-by to full pressure 100 barg in <20 minutes
Flexible load response: instant adaptation to demanding test cycles
Zero energy consumption during stand-by

Conclusion

The Glasgow project stands as a testament to the robust engineering and proven reliability of Clayton steam generators.
In applications where steam quality, uptime, and precision are critical - especially under extreme conditions — Clayton technology continues to set the standard.
