STORAGE FACILITIES FOR SPECIAL RW AND RW DISPOSAL FACILITIES: TASKS FOR THE INFORMATION SUPPORT

The paper considers the future agenda for the information support of activities focused on the safety of facilities for
special RW (SRWF), isolation facilities for special RW (SRWIF) and RW disposal facilities (RWDF) at the pre-closure
and post-closure stages. To justify the considered tasks, the paper evaluates regulatory requirements concerning the
safety assessment and sets forward certain proposals regarding further development of information support particularly
focused on the safety barriers (SB) and monitoring of their evolution following SRWF isolation and RWDF closure,
which is seen to validate the accomplished long-term safety assessments and support the implementation of certain
corrective measures, if necessary. In particular, the paper highlights the following tasks: description of data categories
considered critical when assessing the current state of SRWIF and RWDF safety barriers at the post-closure stage,
which are integrated into the Digital Information Models (DIM) at the final stages of the life cycle, as well as methods
and technologies enabling their periodic radiation monitoring. It also proposes certain steps required to achieve the
ultimate goals of information support.
