6.75. Although the term ‘disposal’ refers to the emplacement of radioactive waste into a facility or a location with no intention of retrieving the waste (see para. 2.9), there may be situations in which there is an intention to provide the possibility of retrieving the waste. The possibility that options for reversing a given step in the development of the disposal facility or for retrieving waste after its emplacement are included in the design is recognized in Ref. [2]. Although such provisions can provide for flexibility in decision making in the development of a disposal facility, they should not be allowed to undermine the long term safety of the facility. Flexibility in the decision making process should not be seen as an objective in itself, but rather as good practice.
