Processing and disposal of solid waste

R&D efforts (Application development linked to plant applications and actual use)

Ongoing projects

Research and Development of Processing and Disposal of Solid Waste(Project of Decommissioning and Contaminated Water Management)
Summary

 Because solid waste generated by the accident contains radionuclides stemmed from damaged fuel, is likely to contain seawater, which came from tsunami and core cooling after the accident, has high dose rate, has varied contamination levels, has a large volume, etc., it has different characteristics from other nuclear wastes generated in the conventional process at nuclear power plants. Therefore, R&Ds for processing and disposing of it safely are in progress. And a study on managing and handling methods of solid waste throughout the process, from its generation in various types and storing to its processing and disposal, is carried out.

Action items
  1. Storage/management
    (1) Study and evaluation of storage/management method
    (2) Development of technology for contamination evaluation to segregate solid waste
  2. Establishment of processing and disposal concept, and development of safety assessment methodology
    (1) Development of selection methodology for preceding processing method
    (2) Proposal of disposal method and development of safety assessment method
  3. Characterization
    (1) Efficiency of characterization
    (2) Development of sampling technologies
  4. Integrating of R&D results (study on waste stream)
