Laboratory Fellows

Deborah Hill was appointed as NNL Laboratory Fellow in the Spring of 2013, covering the area of Criticality Safety. She is currently the Criticality Technical Leader within the FCS Safety, Security and Safeguards team, based at the Preston Laboratory. 

Background

Following the completion of a PhD in x-ray physics at the University of Warwick, Deborah joined British Nuclear Fuels plc (one of the precursor companies to NNL) in 1997 as a graduate trainee in the criticality team. She has since amassed over 18 years of experience providing technical criticality input to a multitude of projects for numerous national and international customers. She is currently a Principal Criticality Safety Consultant and the Criticality Technical Leader within the Safety, Security and Safeguards team; she is responsible for the technical leadership of a large team of criticality specialists, including defining the technical training and assurance requirements plus shaping the technical direction of the team. She was appointed as a Laboratory Fellow for Criticality Safety in early 2013.

 

Key Areas of Expertise

Throughout her career, Deborah has developed considerable experience in both conducting and managing a wide range of operational criticality support to a variety of national and international customers, including shaping site policy and liaising with the nuclear regulators. Using this experience, she has become heavily involved in the development of safety case methodologies and industry standards / guidance. She is now recognised as a national and international expert in the field of criticality safety, having held a number of governance positions on key UK and US criticality committees.

As part of her Laboratory Fellow role, she has been heavily involved in driving the skills agenda with NNL; she has been responsible for the technical community input to the Graduate Development Programme, and is currently the Chair of the NNL Mentoring Community of Practice.
