The Japan Atomic Energy Agency (JAEA) started the JAEA Grout Project (JGP) in 2007, to investigate new grouting technologies and grout materials and to develop models for handling grout effects in performance assessment (PA), prediction of the long-term radionuclide migration and of host rock alteration.
This paper presents an overview of the JGP and an example of how to apply key engineering technologies to the construction and operation of a purpose built underground facility (repository) for the geological disposal of high level nuclear waste (HLW). Further details of the outcome of the JGP can be found in papers (2–5) of the same series (Nakanishi et al., 2012, Bruineset al., 2012, Tanaka et al. 2012, and Koyama et al. 2012).
