Job Description for Senior Criticality Consultant:

This is where your skills play a critical role in keeping everyone safe. Working in Safety, Security & Safeguards gives you the chance to make your mark on some hugely interesting projects. NNL does work that nobody else in the sector is doing, and this means we need experts like you to make it possible, whilst keeping everyone safe. We’re committed to using nuclear science to benefit society for years to come. This means that you can build a long and successful career here whilst playing a meaningful role in delivering cleaner energy, reducing waste and keeping colleagues and the public out of harm’s way.

As the UK nuclear industry is undergoing a resurgence there is an increasing focus on the delivery of new developments, from advanced modular reactors, clean energy, nuclear medicine, new fuel types, new reprocessing processes as well as the need for support of the existing sites and processes, including decommissioning. NNL is at the forefront of many of these developments, particularly with its four Focus Areas, and as a result needs to maintain a position at the forefront of developments in criticality safety assessment. The criticality team at NNL provides criticality safety advice and assessment for our own activities as well as for a number of customers across different licensed sites.
