  "text": "(This note is not part of the Regulations)\nThese Regulations prescribe the type of nuclear matter (“excepted matter”) that falls outside of the liability regime established under the Nuclear Installations Act 1965 (“the Act”). These Regulations revoke the Nuclear Installations (Excepted Matter) Regulations 1978 (S.I 1978/1779).\nIn order to ensure that there is consistency in the various nuclear liability conventions as to what is considered to be excepted matter (and therefore not subject to the liability regimes), the Nuclear Energy Agency Steering Committee has decided to take account of the 2012 Regulations for the Safe Transport of Radioactive Material of the International Atomic Energy Agency (“the IAEA Regulations”). These Regulations reflect that decision and refer to the IAEA Regulations’ description of excepted matter.\nRegulation 3 prescribes the type of material that is considered to be excepted matter, as defined under section 26(1) of the Act. Regulation 3 provides that excepted matter is either small quantities of nuclear substances (including fissile material, but not waste) that is located outside of a nuclear installation (that is, when in transit) provided it meets relevant activity limits and certain packaging and labelling requirements, or reprocessed uranium.\nRegulation 4 prescribes such relevant activity limits, reflecting those set out in the IAEA Regulations.\nThese Regulations come into force on 6th April 2018.\nA full impact assessment has not been produced for this instrument as no, or no significant, impact on the private, voluntary or public sectors is foreseen.",
