A worker at the Sellafield nuclear decommissioning site “died suddenly” during the week commencing 6 July, prompting an immediate review by the Office for Nuclear Regulation (ONR). ONR has confirmed the death was not work-related and that there was no radiological or conventional safety incident affecting the wider site. Routine regulatory oversight of Sellafield’s legacy waste facilities, spent fuel management and construction activities continues unchanged, with no impact reported on nuclear safety cases or site operations.

The British Geological Survey has launched a four‑year ground investigation of the River Tweed catchment to characterise groundwater behaviour and its interaction with river levels for improved flood forecasting. Work will include installing new monitoring boreholes, logging groundwater heads and flow paths, and integrating hydrogeological data with existing river‑gauge and rainfall records across the cross‑border catchment. Findings are expected to refine flood models used by local authorities and infrastructure owners, particularly for groundwater‑dominated flood events and prolonged saturation of transport and drainage assets.

National Trust and United Utilities are installing a series of timber “leaky dams” on moorland and farmland above the Stubbins Estate in Lancashire in a two‑year natural flood management programme to slow runoff into the River Irwell. The structures are designed to back up high flows in small headwater channels while allowing baseflow to pass, temporarily storing stormwater on the floodplain and in upstream depressions. For civil and drainage engineers, the scheme signals continued deployment of low‑cost, nature‑based attenuation measures alongside conventional hard‑engineered defences in upland catchments.
