Richard Hyatt spent the first 18 years of his career in the design and construction of heavy civil engineering structures for both UK and overseas clients. He has particular expertise in the conceptual and detailed design of steel and concrete bridges in accordance with both British and North American design codes of practice. Over the last 17 years he has been deeply involved with the deterministic assessment of safety - critical civil engineering structures forming part of Nuclear Safety Cases. His work has covered detailed FE modelling of structures and mechanical systems under seismic and dynamic fault loads and the production of calculations to UK and US codes of practice and associated engineering safety reports. He has extensive experience in undertaking independent reviews including both IPR of design safety reports and ITA of detailed calculations for buildings, cranes, shiplift platforms and dock gates for the MoD Naval Bases for the effects of blast, seismic and fault loads using BS 5400/5950, the IDWR rules, and Det Norkse Veritas rules for the design of Offshore Structures. He has also assessed safety case

Safe-Crit Structuresdocumentation including, Safety Principles Papers, Safety Justification Plans and Facility Safety Case plans against the requirements and recommendations of the NII SAP's and MoD Regulations of the NNPP, JSP 518. He has prepared numerous engineering substantiation reports for the structural components of at UKAEA Windscale for their Periodic Safety Reviews and for the structures associated with the Prototype Fast Breeder Reactor at UKAEA Dounreay. He has also prepared Safety Assessment and Engineering Substantiation guidance documents for various clients outlining best practice to satisfy modern Nuclear Safety Cases for UK regulatory requirements.

Richard also has invaluable experience in the review of Nuclear Safety Assessments: including Safety-Critical System interactions, HAZAN and HAZOP reports, Fault tree Analysis and Quantified Risk Assessments in order to determine Design Basis Events and evaluate hazard reduction strategies utilising specific knowledge gained from his MSc in Safety Engineering and from the UKAEA training courses: “Radiological HAZAN Production”, “Safety Case Writers Course” and “Independent Peer Reviewers Course”. He has particular interest and expertise in the analysis and design of safety-critical structures for extreme hazard conditions (i.e. seismic, blast, impact, dropped load & fire).
