Disposal end-points

It is the responsibility of the NRWMA to provide final end-points for the respective waste classes. It is therefore assumed that an end-point for all waste categories will exist. The following assumptions are made at this point with regard to the Necsa RAW (the waste is classified in accordance with the Necsa waste classification scheme [8]):

• HLW: No end-point has as yet been decided upon on a national level. For the purpose of this document, disposal in a deep geological facility is assumed for this waste category. On-site storage is not suitable for the long-term storage of this waste class [3]. Interim storage off-site before final disposal will, however, form part of the waste management plan for this waste class.

• ILW (this may also include long-lived sealed radioactive sources such as Ra-226 as well as SHARS): Disposal in a greater confinement trench at the Vaalputs National Radioactive Waste Disposal Facility [3].

• Low-level solid waste (this includes short-lived sealed radioactive sources with limited activity): Disposal in a near-surface disposal facility. The Vaalputs National Radioactive Waste Disposal Facility is identified as the end-point for this waste class [3].

• Very low-level uranium containing bulk waste: Disposal on a mine slimes dam or, with special authorization, disposal in engineered landfill facilities or surface impoundments, general waste landfill facilities and hazardous chemical waste disposal facilities.

• Very short-lived waste: Exemption/clearance will be the final end-point for this material (sealed sources with half-lives <100 days) after being kept on site until sufficiently decayed.
