7Nuclear installation—prescribed activity level for radioactive waste storage facilities

#### 7 Nuclear installation—prescribed activity level for radioactive waste storage facilities (1) For paragraph (c) of the definition of nuclear installation in section 13 of the Act, the activity level, for a radioactive waste storage facility that contains, or is designed to contain, controlled materials, is: (a) if the facility contains, or is designed to contain, unsealed sources, and the result worked out for a waste package of the unsealed sources, using the steps mentioned in subregulation (2) (the activity concentration value steps), is greater than 104—the level at which the result worked out for the unsealed sources in the facility, using the steps mentioned in subregulation (3) (the activity value steps), is 106; or (b) if the facility contains, or is designed to contain, sealed sources—the level at which the result worked out for the sealed sources in the facility, using the steps mentioned in subregulation (3) (the activity value steps), is 1010. > Note: Under section 13 of the Act, a radioactive waste storage facility with an activity that is greater than the activity level prescribed is a nuclear installation. (2) For paragraph (1)(a), the activity concentration value steps are: (a) divide the activity of each nuclide in the waste package by the mass of the waste package; and (b) divide the result for each nuclide worked out under paragraph (a) by the activity concentration value mentioned in an item in the table in clause 2 of Schedule 2 for the nuclide; and (c) if there is more than 1 nuclide in the waste package—add the result for each nuclide worked out under paragraph (b). (3) For paragraphs (1)(a) and (b), the activity value steps are: (a) divide the activity of each nuclide in the sources in the facility by the activity value mentioned in an item in the table in clause 2 of Schedule 2 for the nuclide; and (b) if there is more than 1 nuclide in the sources—add the result for each nuclide worked out under paragraph (a).
