Research Organization for Information Science and Technology (RIST) is a non-profit public-service organization working for the development and utilization of computational science and technology to support highly information-oriented society.
As a predecessor of RIST, Nuclear Energy Data Center (NEDAC) was founded in 1981 in Tokai-mura to promote the development and utilization of nuclear computer codes.
The scope of work was then expanded to incorporate the support of integrated computational science including the support of the Earth Science Projects, and NEDAC was reorganized to RIST in 1995 with the establishment of RIST Tokyo
RIST develops and maintains nuclear codes in the fields of reactor technology, nuclear fusion, nuclear safety, environmental safety, health physics and others related to the application of nuclear science and technology.
Nuclear Code Center
In order to promote the utilization of computer software, Nuclear Code
Center collects, maintain and distribute computer software developed in the wide-ranging field of nuclear
science and technology. Computer codes are collected from
OECD/NEA Data Bank,
ORNL Radiation Safety Information Computational Center,
Japan Atomic Energy Agency and other domestic research organizations.
The nuclear codes are updated and maintained regularly, and the codes are distributed on request to
registered members of the Nuclear Code Center.
- NUCIS -
As a part of the activities of Nuclear Code Center, the information of nuclear codes collected is provided on the internet as NUCIS(Nuclear Code Information Services).
Vast scientific database and the operating systems for handling effectively a fact database on internet are essential for development and utilization of nuclear technology. RIST manages to establish the scientific and technical databases related to nuclear research and development. RIST also develops a fact database on internet for promotion of public acceptance of atomic energy.
Workshops and publications
For promotion of effective use of nuclear software, RIST organizes workshops or seminars, and provides lectures on selected topics or nuclear codes delivered by domestic and foreign specialists. The schedules and plans are informed by "RIST News" and other publications.
