Hinkley Point C (HPC) is the first new nuclear power station to be built in the UK in over 20 years, HPCs two EPR reactors will be capable of generating 3.26GW of secure, low carbon electricity for 60 years, enough electricity to power around 6 million homes. In addition to the projects ‘clean energy’ benefits, HPC will create thousands of jobs and bring lasting benefits to the UK economy.

Amentum are currently recruiting a Piping Design Engineer who will focus on supporting field design activities for the piping discipline within the HPC project. The role involves managing interfaces with multiple disciplines and resolving piping engineering issues encountered during on-site installation of pipework and associated supports. The engineer will ensure compliance with nuclear industry standards and project milestones while maintaining EPR-E procedures. The main tasks will include both Piping Design tasks and Mechanical Calculation tasks:

Key Responsibilities

• •Engaging with various stakeholders (installation contractors, CW interfaces, other disciplines) to clarify issues
• •Producing site request technical assessment (RFI, FCR, NCR) concerning design issues on piping, support and anchorage scopes.
• •Contributing to other teams (Layout, Transverse, etc…) by providing piping assessments or general guidance as required.
