Abstract:
A fire incident is widely considered to be an abnormal occurrence. The present talk provides a summary of the current HSE unit approach on how to estimate a radiological impact of a fire incident originating in an underground research facility on the environment. It includes a short discussion on a few related recurring questions, legal aspects of abnormal occurrences (CH), a fire incident-related definition of release to the environment (dose rate to the public) as well as its calculation, taking into account input parameters such as combustion efficiency, smoke transport and smoke dispersion. A computational method is presented for the assessment of smoke transport, based on the author’s PhD research
