Sellafield Receives Positive Infrastructure Rating

Our SIXEP Continuity Plant has been given a green rating from the Infrastructure and Projects Authority.

This is an important part of the project's journey towards becoming an operational reality on the Sellafield site and to ensure we have continued availability of effluent treatment streams to reduce high hazard and risk reduction.

The Infrastructure and Projects Authority sits at the heart of government, reporting to the Cabinet Office and HM Treasury. It provides expert project delivery advice, support and assurance to ensure projects within the Government Major Projects Portfolio are delivered efficiently and effectively.

All our current major projects - SIXEP Continuity Plant, The Sellafield Retreatment Plant and Replacement Analytical Project - are included in this portfolio, acknowledging their significance to the government and nation.

The Infrastructure and Projects Authority's review team commented:

The project is well run by a highly competent and experienced project team from executive level to on the ground delivery management.

The awareness of project status and emerging issues and the agility to address these issues in a timely fashion demonstrated by the project team is exceptional, as is health and safety awareness and performance.

The SIXEP Continuity Plant is being delivered by Programme and Project Partners, our ground-breaking model to deliver all our major projects over a 20-year period.

The Infrastructure and Projects Authority have seen the delivery model at Sellafield already making a positive impact to the way major projects are being delivered, they want to see how the approach will continually improve and lessons that can help new nuclear infrastructure projects across the industry.

SIXEP Continuity Plant project director Simon Wilcock added:

I'm delighted for the project to have received a green rating from the Infrastructure and Projects Authority, we have also achieved '6 areas of best practice' which is very rare and something we are extremely proud of.

This result is testament, not only to the hard work and dedication of the project team, but the wider Programme and Project Partners, client and supply chain, who are all key to making the highly complex project a success.

A team from the Infrastructure and Projects Authority visited the project on the Sellafield site at the end of January 2023.

The plant will soon take delivery of 2 vessels, and once these are installed will be on track to make its service building watertight.

In accordance with industry best practice we have introduced the role of senior responsible owner for the government major projects portfolio projects. These individuals are directly accountable to parliament for the performance of the projects.

Jeremy Hunt, the interim senior responsible owner for the SIXEP Continuity Plant said:

Taking overall responsibility for the project is a weighty privilege, but the team has made the transition easy. I'd like to thank them for all their hard work to date, which resulted in this fantastic achievement.
