The acceptance criteria, the qualification file(s) and the characterization methodology serve as a guiding principle for the acceptance.

Acceptance consists of verifying the conformity of the radioactive waste produced in an approved facility with the applicable acceptance criteria.

The following administrative and physical conformity checks are performed on the radioactive waste:

If the outcome of these checks is favourable (i.e. assuming there are no reservations), ONDRAF/NIRAS issues the producer with confirmation of the decision to accept the waste - in order to take over the waste definitively - by drawing up an Acceptance Report (technical part) and a Transfer Report (financial part). Accepting radioactive waste not only implies that ONDRAF/NIRAS assumes responsibility for its later management, but also guarantees that the necessary funds are made available to cover the costs of this management.

Other administrative and technical procedures have been developed to monitor the characteristics of the radioactive waste taken over by ONDRAF/NIRAS. They aim at checking periodically whether the accepted waste continues to meet the acceptance criteria applicable at the time of acceptance and whether it is still compatible with the reference solution considered for its long-term management.

Once accepted, the radioactive waste can be physically collected by ONDRAF/NIRAS from the site of their producer.
