Ansaldo NES' engineering department delivers innovation through all stages of the design life of contracts. Nuclear culture is engrained within the department and Ansaldo NES use Suitably Qualified Experienced Personnel (SQEP) who are able to apply their experience and creativity to a slim but robust “gated” system.

With over 60 years' accumulated experience, Ansaldo NES are positioned uniquely within the nuclear market to deliver bespoke and innovative engineering designs.  

From design concept, the Ansaldo NES engineering team works closely with the client to ensure a clear understanding of the client's exacting requirements ensuring that the final solution not only meets but exceeds client expectations. 
Ansaldo NES use proven technology as the basis for design, integrating innovative technologies from other high integrity markets such as oil, gas, chemical and pharmaceutical and applying them to the nuclear environment. Design innovation is supported by experience gained through previously delivered projects.

At Ansaldo NES we pride ourselves on getting it right first time. The use of 3D design tools and Finite Element Analysis (FEA) software ensures that the transition from concept to scheme design and detail design for manufacturing is a continual process, with areas of innovation amalgamated with practical solutions. Fully functional solid scale models are used to test and verify key design areas before continuation into scheme and detail design for manufacturing. During the delivery of the scheme design and detail design for manufacturing, Ansaldo NES' engineering department is supported by the use of advanced visualisation and virtual reality design tools.
