6.36. Criteria for determining whether safety function indicators are met will be an aid in determining whether safety will be achieved. As there will be a range of safety functions, safety function indicators and criteria, a failure to meet a criterion for a particular safety function indicator does not necessarily mean that the disposal system fails to comply with regulatory limits or targets (e.g. on dose or risk) but, rather, that more elaborate analyses and data are needed in order to evaluate safety Other ways of demonstrating defence in depth include evaluation of other measures of performance of the disposal facility (e.g. the containment of different radionuclides within different barriers) and presentation of the results.
