Japaneese authorities wants to examine the condition of the materials used in the construction of Japans nuclear reactors. Concrete is the material most commonly used to shield the core of the reactor. There is litle knowledge of how concrete responds to irradiation over a long periode of time. The in-pile tests will be done at the Jeep-II research reactor at Kjeller while the out-pile test will be done at IFEs Halden facilities.

The cooperation with Kajima dates back to 2009. This new project is an extension of previous work and is based on the results from the initial projects.

Kajima Corp. is one of the largest engineering companies in Japan and ha been a major constructor of nuclear reactors in Japan. In addition to Kajima, Mitsubishi Research Institute and Nagoya University will also take part in the project.
