Celeros Flow Technology to Supply Sizewell C with Safety-Critical Nuclear Pump Packages

Jose Larios, CEO of Celeros FT, commented: “We are proud to be contributing to Sizewell C, which is one of the largest net-zero projects in the UK and will play a key role in the energy transition. Our in-house nuclear engineering expertise and world-class manufacturing and testing facilities are a winning combination that will add real value to this project. As a long-term partner to EDF, we have supplied safety-critical flow control systems for almost all their nuclear power plants in France and the UK. Our ClydeUnion Pumps team is now working collaboratively with the Sizewell C project team to ensure that the nuclear pump packages meet all regulatory and design criteria for this landmark project.”

Sizewell C is being constructed alongside the existing Sizewell B on the East Suffolk coast. It will be capable of generating 3.2-gigawatts of power, sufficient to supply six million homes with low-carbon electricity for at least 60 years, and will avoid nine million tonnes of CO2 for every year of operation. As a generator of low-carbon electricity and heat, Sizewell C can also help to kickstart other net zero technologies such as hydrogen production and direct air capture (DAC).

Nuclear pump solutions

ClydeUnion Pumps is tasked with manufacturing numerous safety-critical pump packages for the Sizewell C nuclear power station. These include the pumps for the following systems:

• The Emergency Feedwater System (ASG), that supplies the required rate of water to the steam generator’s secondary side if all the systems contributing to normal supply of the steam generators are unavailable.
• The Component Cooling Water System (RRI), which is designed to cool and transfer heat load from various components and systems within the nuclear island during different operating conditions of the nuclear plant units.
• The Safety Injection System (LHSI and MHSI ), which stops the nuclear reactor and supplies it with a constant source of water during a coolant loss incident.
• The Nuclear Island Vent/Drain System (RPE), which guarantees the confinement of radioactive substances in the event of an accident by transferring contaminated fluids to the reactor building.
• The Safety Chilled Water System (DEL ), which supports the general operation of the plant by producing and distributing chilled water for HVAC systems.

Celeros Flow Technology brings considerable experience and expertise to the Sizewell C project. Their involvement in the nuclear power market began with the first ever industrial scale nuclear power plant. Since then, they have been central to many major nuclear power programs globally and their nuclear pumps and valves are installed in more than 65% of operational nuclear power plants globally. Through their four nuclear-accredited facilities, Celeros Flow Technology is also involved in the research and development of flow control solutions to meet current and future nuclear technologies, such as generation IV, fusion and small modular reactors.

In addition to the commercial nuclear power market, the company’s solutions are also found in the world’s naval nuclear fleets, research reactors and other nuclear facilities.
