Revised Licensing Nuclear Installations guidance

27 September, 2019

The Office for Nuclear Regulation (ONR) has revised its Licensing Nuclear Installations guidance. The revised guidance replaces the 4th edition, published in January 2015.

The key changes to the guidance have been made to reflect legal changes as a result of the introduction of new legislation and to include reference to updated processes and procedures.

Licensing Nuclear Installations describes how ONR regulates the design, construction and operation of any nuclear installation in GB for which a nuclear site licence is required under the Nuclear Installations Act 1965. Such installations include nuclear power stations, nuclear fuel manufacturing facilities, nuclear defence facilities for weapons manufacturing and fuelling/maintenance of nuclear submarines, reprocessing facilities and facilities for the storage of bulk quantities of radioactive matter which has been produced or irradiated in the course of the production or use of nuclear fuel.
