Dr Alastair ClarkManaging Director and Principal Consultant
Dr Alastair Clark is a geologist and technical integrator, specialising in radioactive waste management with academic training and 15 years’ professional experience. Alastair has a unique mix of technical understanding, data analysis and project management skills tailored to the radioactive waste management and disposal, covering the engineering design and post-closure performance assessment of the UK’s near-surface repository for Low Level Waste and the UK’s deep geological disposal facility (GDF) for Higher Activity Waste. sector. His experience covers strategy, programme development, siting, site characterisation, packaging, engineering design and post-closure performance.
Alastair has a PhD in geochemistry which was sponsored by British Nuclear Fuels (BNFL) Ltd to investigate the long-term evolution of the wasteform used to immobilise Low Level Waste. After his PhD, he led an environmental consultancy, reporting to the Executive Board and coordinating a multi-disciplined research team across the Universities of Manchester and Newcastle.
He worked for Nirex and the Nuclear Decommissioning Authority Radioactive Waste Management Directorate (RWMD) for 8 years and during this time was Design Systems Engineer and Engineering Manager. Over this time, Alastair was RWM’s Intelligent Client for engineering design process development, geotechnical engineering, GDF nuclear safeguards, GDF physical protection, and geospatial management and he also led the implementation of RWMD’s Design Authority arrangements. During his time at RWMD, Alastair led a £5 million, 4 year critical-path project to prepare for the identification and assessment of potential UK geological disposal facility sites. This involved co-ordination of the technical programme integrating spatial, geological and site-specific design development.
Since joining MCM Consulting, Alastair has led work to develop and test RWM’s disposal concept selection process and develop concepts for the disposal of spent fuel in Multi-Purpose Containers. He currently supports LLWR Ltd by leading the development of a Requirements Management System to support engineering design optimisation and the LLWR Environmental Safety Case. He is also currently Key Expert for the engineering design of Iraq’s Low and Intermediate Level Waste repository.
