Large Deaerator Pressure Vessels for the Nuclear Industry in South Wales, UK
LTi Vessco is proud to play a key role in the UK’s nuclear energy sector, including the development of large deaerator pressure vessels for critical applications. Our expertise in designing and manufacturing high-specification equipment for the nuclear industry has earned us prestigious accolades, including the Fit for Nuclear (F4N) standard. Based in South Wales, we are positioned as a trusted supplier to some of the most significant infrastructure projects in the country, including Hinkley Point C (HPC) Power Station.

Specialised Equipment for Hinkley Point C
LTi Vessco is currently fulfilling a contract for a large deaerator pressure vessel destined for the turbine island at HPC, one of the most ambitious nuclear projects in the UK. Combining a deaerator and feed water tank, this vessel is engineered to exceptional standards to meet the demanding requirements of nuclear energy generation.
-
- Massive Scale: The vessel, weighing over 330 tonnes, represents one of the largest pieces of equipment we have ever manufactured. Due to its size, it will be fabricated in sections at our facility in South Wales and then shipped to the HPC site for final assembly.
- Critical Functionality: By combining a deaerator and feed water tank in one integrated design, the vessel ensures efficient removal of dissolved gases from boiler feedwater, improving turbine efficiency and reducing the risk of corrosion.
Commitment to Excellence in the Nuclear Sector
Our experience in manufacturing large deaerator pressure vessels and other complex systems for the nuclear industry underscores our commitment to safety, quality, and innovation. We are proud to be members of the Wales Nuclear Forum, a network that supports businesses in the nuclear supply chain.
Meeting the Fit for Nuclear (F4N) Standard
Achieving the F4N standard reflects our dedication to continuous improvement in all aspects of our business. To meet this rigorous benchmark, we implemented significant changes in our management practices, fostering a culture of collaboration and accountability among all employees. Every team member contributes to maintaining our high standards and ensuring the success of our projects.
Precision Engineering for Nuclear Applications
Manufacturing equipment for the nuclear sector demands meticulous attention to detail. From material selection to final assembly, every step of the process adheres to stringent standards:
-
-
- Material Identification and Traceability: Ensuring complete provenance for all components, a critical requirement for nuclear applications.
- Product Cleanliness: Maintaining the highest standards of cleanliness to prevent contamination during manufacturing and operation.
- Welding Perfection: Employing advanced techniques and rigorous inspections to guarantee the structural integrity of pressure vessels.
- Safety First: Upholding the highest safety standards for workers during fabrication and for end-users during operation.
