Sellafield Site full Large

Project:

Management & Operation of Sellafield Ltd, UK

Amentum-led global nuclear industry consortium, Nuclear Management Partners (NMP), was awarded a multi-billion pound contract to manage and operate the Sellafield site in West Cumbria, England, UK. The site is one of the UK’s largest industrial and construction sites and widely regarded as the world’s most complex and challenging nuclear site. The site has 1,200 buildings, over 200 contain nuclear inventory and 100 are categorised as being equivalent to a nuclear reactor in terms of potential hazard and security status. There are more than 450 ongoing engineering and construction projects with 19 valued at over £100 million.  NMP operated the site from 2008-2016.

Leaders and specialist from NMP’s parent organisations were strategically deployed to coach and train incumbent Sellafield employees whilst also introducing managerial and technical innovations to address immediate and emerging issues. This led to enhanced and sustainable capability on the site and a positive turnaround in performance.
