[en] In response to the invitation by the U.K. Secretary of State for Energy for interested individuals or organisations to submit questions to the Nuclear Installations Inspectorate, a document has been published by the organisation 'Friends of the Earth' which poses many questions relating to nuclear safety. To determine which of these might be appropriate to ask the NII, a brief survey is first presented of the responsibilities of the NII and other bodies, such as the Health and Safety Executive, with responsibilities in the field of nuclear safety and security. Some critical comments concerning existing arrangements, and some general questions, are put forward for discussion. Many detailed questions are then presented for the NII to answer on a number of issues concerning the safety of nuclear reactors, plants, and processes. These relate to specific incidents occuring in, and problems encountered with, Magnox reactors, problems of the SGHWR, specific aspects of fast reactor safety, and finally, numerous questions concerning reprocessing and waste.
