The role

As a Principal Piping Stress Engineer, you'll have a role that's out of the ordinary. You'll lead the stress analysis and integrity of complex piping systems that sit at the heart of a nationally critical programme - including new fuel conversion capability being delivered at the Springfields site in Preston.

Cavendish Nuclear is powering one of the UK's most strategically important nuclear programmes, partnering with Springfield Fuels Limited to deliver a brand new, cutting edge facility at the Springfields site in Preston that will convert Reprocessed Uranium into UF6 at a scale of 2,500 tonnes per year. This nationally critical project, featuring a new RepU conversion plant, a Fluorine Production Plant and modern support facilities, is set to be operational by 2031, and we're building a major multidisciplinary team to make it happen.

Day to day you'll be required to:

• Lead the piping stress analysis design basis, critical line list and support specifications for complex process and power systems.
• Perform piping stress analysis and pressure vessel assessments using Hexagon Caesar II and PV Elite, including static/dynamic flexibility studies.
