Nuclear Safety - At Our Core

Our equipment, from Auxiliary Feed Pumps to Safety Injection Pumps, is engineered for critical safety applications. Accordingly, we prioritise the safe and reliable operation of your assets.

For example, one customer runs a number of Emergency Feedwater Pump Packages, which were first installed in a power plant in France in 1972. These pumps continue to operate efficiently and are upgraded every 15 years. We support our customer by re-evaluating, modifying, and maintaining the pumps to ensure they meet current safety qualifications.

Our dedicated team is always ready to solve problems and find appropriate solutions, keeping your equipment safe and reliable throughout its lifetime. We are deeply committed to a culture of safety and fully understand the critical roles our pumps play in nuclear operations.

Nuclear Field Service Support

Our global aftermarket organization provides comprehensive service and upgrade solutions. With a dedicated team of nuclear-qualified engineers, we offer the following field service support capabilities:

  • Commissioning & Installation
  • Site Product Training
  • Hot line and technical assistance
  • Studies / Calculations / Seismic re-evaluations / Original qualification verification to accidental conditions verification

Engineering Capability – We Find the Solutions to Your Problems

We understand the critical importance of engineering for our nuclear customers. Our expertise is especially vital when recalculating data or resizing equipment to meet evolving needs. Seismic and thermal conditions are frequently reassessed, and we ensure that our customer’s equipment remains appropriate and reliable under these changing circumstances.

We can conduct comprehensive studies before supplying equipment, where conditions are evaluated and the suitability of the pumps is reassessed. This includes checking material specifications, designations, and compliance with required standards to guarantee compatibility and reliability over time.

Our robust engineering capabilities enable us to adapt to changing system and thermal conditions, ensuring that our solutions remain effective and dependable throughout the entire lifecycle of your equipment.
