Decision Analysis and Options Studies
GSL is a world leader in the conduct of optioneering studies, including Best Practicable Environmental Option (BPEO), as well as public and stakeholder consultation exercises. Our experience includes both the preparation of documentation to support optioneering conferences, development of optioneering and decision analysis methodologies, and meeting organisation, facilitation and reporting.
For example, GSL staff have supported Dounreay in the conduct of BPEO studies for LLW management, the shaft end-state, the treatment of active solvents and oils, the management of radioactive particles in the environment around Dounreay, Prototype Fast Reactor raffinates, and the site end state, amongst others, including facilitation, conduct and consultation of the studies. We have also undertaken BPEO assessments for decommissioning of Windscale Pile 1 and Pile 2, and for development of a site-wide Integrated Waste Strategy (IWS) at the Windscale site.
We have worked with British Nuclear Group Sellafield Limited (BNGSL) on a Baseline BPEO study for remediation of the Legacy Ponds and Legacy Silos (LP&LS) facilities, a BPEO study for treatment of wastes from the Magnox Wet Silo, a BPEO study for the Sellafield Legacy Pond Solids treatment, and a BPEO study for development of an IWS for the Sellafield site. We have undertaken a BPEO study for the management of spent ion exchange resins at the Sizewell B power station. We have also undertaken a multi-criteria options study for the complete removal and management of the boilers at the Trawsfynydd Decommissioning Site in which we developed the optioneering methodology specifically for this project.
GSL has experience using industry-standard software to support options analysis, such as the HiView and OnBalance™ packages, and we have developed our own purpose-built software for transparent presentation of BPEO studies and sensitivity analyses.
Radioactive waste disposals and discharges must be authorised by the UK Environment Agencies’ who require a demonstration that available waste management options have been considered and the BPEO identified, and that Best Practicable Means (BPM) are being used to minimise the impact of any discharges / disposals. All of the BPEO studies GSL has conducted have been consistent with or based on procedures documented by the Environment Agencies. We are fully conversant with Environment Agency and industry guidance on the conduct of BPEO studies, and have been a lead contributor in the UK to the development of BPEO methodology.
Indeed representatives of the regulators participated (as Observers) in BPEO workshops that we organised and facilitated concerning waste management at Windscale and Sellafield. Find more information here: GSL Optioneering Services
