title: Best practicable means (BPM) and as low as reasonably practicable (ALARP) in action at Sellafield.
abstract: Operators within the UK nuclear industry are required to employ 'best practicable means' (BPM) to control and minimise radioactive discharges. The requirement for the use of BPM is in order to ensure that doses from discharges are as low as reasonably practicable (ALARP). This facet is increasingly becoming the principal feature of discharge authorisations issued by the Environment Agencies under the Radioactive Substances Act, 1993 (RSA 93), which are enforceable by law. It is important to state at the outset, however, that scientific assessments to date indicate that there are no expectations of environmental harm from authorised discharges, even where those discharges have historically been up to two orders of magnitude higher than current levels. There is also no evidence to indicate that foreseeable future discharges from the Sellafield site will make any contribution to environmental harm.
