8.4. In order to facilitate the evaluation of the safety case against the primary objectives of the regulatory review, it is common for a number of secondary objectives to be specified. These should include evaluation of whether the safety case:@@- Has been developed within an appropriate context; @@- Is sufficiently complete, given the stage of development of the disposal facility;@@- Is sufficiently transparent in its presentation of data and information; @@- Has been prepared by competent personnel applying an approved management system;@@- Has been subjected to independent peer review;@@- Is based on appropriate assumptions and makes use of adequate assessment techniques and models, and contains satisfactory supporting arguments;@@- Demonstrates an adequate understanding of the disposal system that includes identification and screening of hazards and related scenarios, such that all relevant safety functions and all potential safety concerns are addressed;@@- Clearly describes how the identification, establishment, justification and optimization of limits, controls and conditions were performed;@@- Clearly identifies the uncertainties associated with the understanding of the disposal system (as well as input data and models used) and the performance of the disposal facility;@@- Provides an adequate assessment and supporting justification that any radiation exposure has been optimized and demonstrates that safety has been optimized;@@- Includes adequate consideration of the justification and optimization of remedial measures for existing facilities, if applicable;@@- Addresses all relevant factors of the management system to be applied for the siting, construction, commissioning, operation and closure of the disposal facility (e.g. internal and external audits, verification and validation, use of suitably qualified and experienced personnel, training, control of processes outsourced to subcontractors, action on conclusions and recommendations);@@- Demonstrates that good engineering practices with adequate defence in depth have been used in developing the design of the facility;@@- Defines a programme for future development of the safety case, understanding the disposal system and institutional control of the site.
