Focusing on the cover layer materials (as the Radon Barrier Materials), which could have the effect to restrain the radon from scattering into the air and the effect of the radiation shielding, we produced the radon barrier materials with crude bentonite on an experimental basis, using the rotary type comprehensive unit for grinding and mixing, through which we carried out the evaluation of the characteristics thereof.

Since earthquake surely takes place in Japan, safety on nuclear power plant (NPP) against earthquake is one of the most important issue. In April 2016, a research council of "Basic Safety Principles on Earthquake Engineering for Nuclear Power Plants" was established in Japan Association for Earthquake Engineering (JAEE) to clarify a basic concept and a practice of the safety principles among a mature discussion by engineers in a wide range of nuclear safety and earthquake engineering fields. In the present report, the summery of the basic safety principles is introduced and a sufficient exchange of views will be conducted through the session.

The research committee on "Basic Safety Principles on Earthquake Engineering" was established in Japan Association for Earthquake Engineering (JAEE) to propose the basic safety principles on earthquake engineering for nuclear power plants (NPPs) based on defense in depth and also risk concept. In the committee, three working groups were also established. In working group 1 (WG1), which was parallel established as a subcommittee of "Basic Safety Principles on Earthquake Engineering" in Atomic Energy Society of Japan (AESJ), the contents of the basic safety principles on earthquake engineering has been discussed and the material for discussion has been summarized. This paper summarizes the basic principles and points of contention through the discussion.
