Nuclear power

Our involvement in the nuclear power market began with the first ever industrial scale nuclear power plant and continues with ClydeUnion Pumps having nuclear pump installations in over 65% of operational nuclear power plants worldwide.

ClydeUnion Pumps offers a comprehensive Class 1, Class 2 and Class 3 product range and can also provide a full conventional island product offering designed for the high reliability and availability requirements of a nuclear facility. Key to our success in both civil and naval nuclear power is our ability to acquire and maintain the high standards required to design and build nuclear coded pumps. Our three coded facilities - Glasgow-UK, Annecy-France and Battle Creek-USA, are all qualified to ASME “N Stamp” and/or RCC-M and have a long history of excellence.
