WENRA harmonized decommissioning reference levels report - 10 - Safety assessment Assessment of all aspects of the siting, design, operation and decommissioning of an authorized facility that are relevant to protection and safety. Safety case A collection of arguments and evidence in support of the safety of a facility or activity. This will normally include the findings of a safety assessment and a statement of confidence in these findings. Safety policy A documented commitment by the licensee to a high nuclear safety performance supported by clear safety objectives and targets and a commitment of necessary resources to achieve these targets. The safety policy is issued as separate safety management document or as visible part of an integrated organisation policy. Structures, systems and components (SSCs) A general term encompassing all of the elements (items) of a facility or activity which contribute to protection and safety, except human factors. - Structures are the passive elements: buildings, vessels, shielding, etc. - A system comprises several components, assembled in such a way as to perform a specific (active) function. - A component is a discrete element of a system. use Authorized use: Use of radioactive materials or radioactive objects from an authorized practice in accordance with an authorization. Restricted use: The use of an area or of materials, subject to restrictions imposed for reasons of radiation protection and safety. Restrictions would typically be expressed in the form of prohibition of particular activities (e.g. materials may only be recycled or reused within a facility). Unrestricted use: The use of an area or of materials without any radiologically based restrictions.
