The JET project at Culham, Oxfordshire, UK, part of the Euratom Fusion Programme, is regulated by Her Majesty's Inspectorate of Pollution (HMIP) with regard to the holding of radioactive materials and the disposal of radioactive waste. JET has had to justify the holding of radioactive material and their radioactive waste management plans to HMIP. JET have been authorised by HMIP to discharge radioactive waste within limits and under specified conditions in order that national and international radiation dose limits to members of the public are not exceeded. There is an overlying requirement by HMIP that the discharges are limited by the use of the best practicable means (BPM) so that radiation exposures from JET's discharges are kept as low as reasonably achievable (ALARA). The HMIP Inspector has powers under the Radioactive Substances Act 1960 which allow him to inspect JET and carry out any relevant tests or measurements. The Inspector also ensures that JET has an appropriate monitoring programme in order to assess radiation doses in the environment.
