Nuclear matter that meets the requirements of F1paragraph (2), (3) or (4) is prescribed as excepted matter for the purposes of the definition of that expression in section 26(1) of the Act.
The requirement in this paragraph is that the nuclear matter is a substance consisting substantially of uranium in which—
the total activity content per gram of that substance of all radioisotopes, other than any uranium isotopes which are normally present in natural uranium or any daughter products of such uranium isotopes—
does not exceed 3.3 kilobecquerels for all alpha emitting isotopes;
does not exceed 0.74 megabecquerels for all beta or gamma emitting isotopes; and
the mass of any isotope uranium 235 does not exceed 1% of the total mass of all the uranium isotopes present.
The requirement in this paragraph is that, for such time as it is outside a relevant site, the nuclear matter (other than waste discharged on or from a relevant site or consigned from a relevant site) has been consigned from a relevant site and at the time when it left that site—
it was duly packed and labelled in accordance with the appropriate provisions of the IAEA Regulations (for nuclear matter that is fissile material, this requirement includes compliance with paragraphs 417(a) – (f) of the IAEA Regulations), and
it did not exceed the activity limits prescribed in regulation 4.
The requirement in this paragraph is that the nuclear matter has been disposed of in an installation for the disposal of nuclear matter on an excluded disposal site.
