Management of Radioactive Waste
Requirements related to management of RAW are defined in the Atomic Act and in the decree of UJD SR No. 30/2012 Coll. Under the term of RAW management the integrated system covering collection, sorting, storage, treatment, conditioning, handling and disposal of RAW from nuclear installations as well as conditioning and disposal of IRAW is understand.
UJD SR executes the state supervision upon the nuclear safety during all stages of RAW management from nuclear installations and also during the final stages of IRAW management.
Present strategy of RAW management is based on following steps:
- conditioning of RAW into the form suitable for disposal or long term storage,
- disposal of low and intermediate radioactive RAW to the surface repository and long term storage of RAW which is unacceptable for surface repository,
- research and development of deep repository for disposal of RAW which is unacceptable for surface repository
This strategy is in compliance with international Joint Convention on safety of spent nuclear fuel management and on safety of management of RAW, which the Slovak Republic ratified as one of first IAEA member states by the end of September 1998 and it is a part of regularly submitted national report.
All activities during RAW management shall be directed towards safe disposal thereof. Centralized facilities for treatment and conditioning of RAW into the form appropriate for its disposal to repository, so called fibre reinforced concrete container, are available at both sites. RAW is treated by incineration, super-compaction, fixation into the concrete, glass, bitumen, paraffin and geopolymere matrices. Storage of RAW represents the important role between the RAW generation and individual steps of its management.
