The operation was completed promptly and resulted in a significant reduction in risk for the facility. Radiological doses recorded during the task were impressively low: the maximum extremity dose was 5 mSv, the highest eye lens dose was 0.5 mSv, and the maximum whole-body dose was just 0.2 mSv.
This case highlights the importance of integrating radiological protection with industrial safety and human factors. A temporary storage solution had evolved into a major hazard, but through expert advice, careful planning, and open communication, both explosive and radiological risks were successfully mitigated. The operators involved were later recognised internally for their professionalism and commitment, a testament to the value of collaborative safety culture in high-hazard environments.
As the nuclear sector continues to manage legacy waste challenges, this example from Sellafield offers valuable lessons. Radiological protection is not just about instruments and regulations – it is about understanding the full context of risk, engaging with those on the front line, and ensuring that safety measures are both technically sound and practically reassuring.
What is a glovebox? A nuclear glovebox is essentially a sealed container with built in gloves that allow operators to handle radioactive materials safely. They vary in size, design and purpose but are commonly made up of a steel frame and panels made of metal or Perspex.
Long PVC gloves are built into the box so operators can safely handle nuclear materials without risking contamination. They may also wear additional lead-lined, heat resistant gloves depending on the type of work they are doing. The atmosphere inside the box is controlled and ventilated and materials are placed inside via an entry port to maintain containment.
