The package shall also meet the requirements prescribed elsewhere in these Regulations which pertain to the radioactive and fissile properties of the material.
Subregulation 2
Each package designed to contain 0.1 kg or more of uranium hexafluoride shall be designed so that it would meet the following requirements:
withstand without leakage and without unacceptable stress, as specified in the International Organisation for Standardisation document ISO 7195, the structural test as specified in paragraph 4 of Section E of the Fourth Schedule;
withstand without loss or dispersal of the uranium hexafluoride the test specified in paragraph 5(4) of Section E of the Fourth Schedule; and
withstand without rupture of the containment system the test specified in paragraph 7(3) of Section E of the Fourth Schedule.
Subregulation 3
Packages designed to contain 0.1 kg or more of uranium hexafluoride shall not be provided with pressure relief devices.
Subregulation 4
Subject to the approval of the Chief Executive, packages designed to contain 0.1 kg or more of uranium hexafluoride may be transported if —
the packages are designed to requirements other than those given in ISO 7195 and paragraphs (2) and (3) but, notwithstanding, the requirements of paragraphs (2) and (3) are met as far as practicable;
the packages are designed to withstand without leakage and without unacceptable stress a test pressure less than 2.8 MPa as specified in paragraph 4 of section E of the Fourth Schedule; or
for packages designed to contain 9000 kg or more of uranium hexafluoride, the packages do not meet the requirement of paragraph (2)(c).
