Paragraph 2

Original text. Later amendments are not shown.

A packaging for fissile material shall be so designed that, if it were subjected to the tests specified in paragraphs 6–11 of Part III of Schedule 15:

(a)

Neither the volume nor any spacing on the basis of which nuclear criticality control for the purpose of paragraph 6(a) has been assessed would suffer more than 5% reduction, and the construction of the packaging would prevent the entry of a 10 cm cube; and

(b)

Water would not leak into or out of any part of the package unless water in-leakage into or out-leakage from that part, to the optimum foreseeable extent, has been assumed for the purposes of paragraphs 5 and 6; and

(c)

The configuration of the radioactive contents and the geometry of the containment system would not be altered so as to increase the neutron multiplication significantly.
