# The Nuclear Installations (Prescribed Sites and Transport) Regulations 2018

S.I. 2018/42 · made 16 January 2018

These Regulations prescribe the sites and transport for which lower liability limits apply under the Nuclear Installations Act 1965 (“the Act”). The liability regime imposed by the Act on operators of nuclear sites and disposal sites taking nuclear waste sets the standard liability limit at €1200 million, but allows a lower limit to be set for sites and transport prescribed under section 16(1) of the Act. These Regulations do not apply to excepted matter, which is the subject of separate regulation, the Nuclear Installations (Excepted Matter) Regulations 2017 (S.I. 2017/920).

(4) The purpose in this paragraph is installing or operating a small nuclear reactor where the radioactive material present outside the reactor at any time, other than associated nuclear fuel, meets the condition in paragraph (5).
(5) The condition in this paragraph is that the quantity of any radionuclide listed or described in Schedule 2 which is present in the radioactive material does not exceed half the limit specified for that radionuclide in that Schedule.
(6) For the purpose of paragraphs (3) and (5), a limit specified in Schedule 2 is exceeded if—
(a) where the radioactive material contains only one radionuclide, the quantity of that radionuclide exceeds the limit specified in the appropriate entry in the table in Part 1 of that Schedule, or in the case of paragraph (5), half that limit; or
(b) where the radioactive material contains more than one radionuclide, the quantity ratio calculated in accordance with Part 2 of that Schedule exceeds one.
(7) In this regulation—
“associated nuclear fuel” means a quantity of nuclear fuel intended and ready for use or in use or which has been used in a nuclear reactor and which is held in, or on the same site as, that nuclear reactor which does not exceed the quantity of nuclear fuel specified in the nuclear site licence relating to that nuclear reactor or any consent or approval granted under that site licence;
“fissile material” means plutonium 239, plutonium 241, uranium 233, uranium 235 (where the mass of the isotope uranium 235 exceeds 1% of the total mass of all the uranium isotopes present), or any material containing any of them;
“small nuclear reactor” means a thermal neutron nuclear reactor designed to operate at a thermal power output not exceeding 600 kilowatts.

## 4 Sites prescribed for the purposes of section 16(1)(b) of the Act (low risk disposal sites)

There is prescribed for the purposes of section 16(1)(b) of the Act any relevant disposal site which is used for the disposal of low level waste, and which is not used for the disposal of any nuclear matter that is not low level waste.

## 5 Sites prescribed for the purposes of section 16(1)(c) of the Act (intermediate risk nuclear sites)

(1) There is prescribed for the purposes of section 16(1)(c) of the Act any licensed site which—
(a) has been, but is no longer being used for the generation of electricity, and from which the nuclear fuel has been removed permanently from the reactor and stored safely in accordance with relevant good practices;
(b) is used for one or more of the purposes set out in paragraphs (2) to (5);
(c) has been, but is no longer being used for one or more of the purposes set out in paragraphs (2) to (5), and which is being decommissioned; or
(d) would be a site prescribed by regulation 3 but for the limit on the mass of fissile material specified in regulation 3(1)(b), or the limit on quantity specified in regulation 3(3) or 3(5), being exceeded.

## 2 Quantity ratios for more than one radionuclide

Where n equals the total number of radionuclides.

## 1 

For the purpose of regulation 3(6)(b), the quantity ratio for more than one radionuclide is the sum of the quotients, for each radionuclide present (i), of the quantity of that radionuclide Qp divided by the quantity of that radionuclide specified in the appropriate column of Part 1 of this Schedule Qlim, namely—
∑ i=1 n Q p (i) Q lim (i)

## 2 

In any case where the isotopic composition of a radioactive substance is not known or is only partially known, the quantity ratio for that substance must be calculated by using the values specified in the appropriate column in Part 1 for “other radionuclides not listed above” for any radionuclide that has not been identified or where the quantity of a radionuclide is uncertain.

## Explanatory note

(This note is not part of the Regulations)
These Regulations prescribe the sites and transport for which lower liability limits apply under the Nuclear Installations Act 1965 (“the Act”). The liability regime imposed by the Act on operators of nuclear sites and disposal sites taking nuclear waste sets the standard liability limit at €1200 million, but allows a lower limit to be set for sites and transport prescribed under section 16(1) of the Act. These Regulations do not apply to excepted matter, which is the subject of separate regulation, the Nuclear Installations (Excepted Matter) Regulations 2017 (S.I. 2017/920).
All but one of the categories prescribed by these Regulations are new and result from the extension of the liability regime by prospective amendments to the Act made by the Nuclear Installations (Liability for Damage) Order 2016 (S.I. 2016/562).
Regulation 3 prescribes low risk nuclear sites, which are broadly the same sites as those prescribed by the Nuclear Installations (Prescribed Sites) Regulations 1983 (S.I. 1983/919) which these Regulations revoke. The liability limit for these sites is €70 million (see section 16(1)(a) of the Act). These are sites licensed under the Act which are used for (i) small nuclear reactors or (ii) storage of radioactive material (within the radioactivity limits set out in Schedule 1); and in both cases subject to restrictions (set out in Schedule 2) on the quantity of fissile material at the site.
Regulation 4 prescribes low risk disposal sites, for which the liability limit is €70 million (see section 16(1)(b) of the Act). These are disposal sites taking only low level waste as defined in regulation 2.
Regulation 5 prescribes intermediate risk nuclear sites, for which the liability limit is €160 million (see section 16(1)(c) of the Act). These are sites used for purposes for which the risk is higher than for low risk sites, but which do not justify the standard liability limit.
Regulation 6 prescribes low risk transport, for which the liability limit is €80 million (see section 16(1)(d) and (e) of the Act). These are situations where nuclear matter transported from a licensed site or a disposal site meets prescribed conditions, namely that the matter is in packages that do not exceed radioactivity levels set by reference to values used in the IAEA Regulations for the Safe Transport of Radioactive Materials 2012.
Regulation 7 requires the Secretary of State to review the operation and effect of these Regulations and publish a report within five years after they come into force and within every five years after that. Following a review it will fall to the Secretary of State to consider whether the Regulations should remain as they are, or be revoked or be amended. A further instrument would be needed to revoke the Regulations or to amend them.
These Regulations come into force when the prospective amendments to the Act come into force.
A full impact assessment of the effect that this instrument will have on the costs of business and the voluntary sector has been prepared in relation to low risk disposal sites and low risk transport, in conjunction with the Nuclear Installations (Liability for Damage) Order 2016. That assessment is available from the Department for Business, Energy and Industrial Strategy at 1 Victoria Street, London, SW1H 0ET and is published with the Explanatory Memorandum to these Regulations and to the Order respectively on www.legislation.gov.uk. A full impact assessment has not been produced for this instrument in relation to intermediate sites as no, or no significant, impact on the private, voluntary or public sectors is foreseen.
