The concept and methods of verification for wastes generated from normal nuclear power plants have been established. However, it is difficult to apply them to the accidental Fukushima Daiichi NPS. Instead, it is necessary to have a examination and analysis method for waste package specific to the accident reactor.

From the viewpoint of the cost and the work efficiency, it is also necessary to establish a rational method for verifying the waste package according to the features of accident wastes.

For instance, there are some cases assumed such as examining by type approval, storing the records in accordance with a manual that describes the removal of hazardous substances at the waste generation stage, ensuring quality by setting and managing appropriate operational conditions and parameters for processing, and so on. Finally, it is necessary to investigate an overall strategy, including procedures for examining that waste package features satisfies the required criteria of the repository.
