Fifty years ago (1962) a group of scientists and nuclear programme managers from 18 European and North American countries established under the auspices of the Organisation for European Economic Co-operation (OEEC now O.E.C.D.) the European-American Committee on Reactor Physics (EACRP).

This Committee, renamed Nuclear Energy Agency Reactor Physics Committee (NEACRP) when Japan joined, has played an essential role in developing "Reactor Physics". International cooperation in this field was established, information was exchanged that was not available in the literature, common projects were set-up and completed, and overall an outstanding progress was achieved. This Committee was then reorganised together with others, which gave birth to the Nuclear Science Committee in 1992.

This archive contains information on when and where this Committee held its meetings, and who formed the Bureau of the Committee. The many scientists who have contributed to this effort, either by representing the work of their countries or carrying out work shared within this Committee are listed on separate tables.

In all over 1500 reports were presented at these meetings from 1962 to 1991. Most of them are still accessible, others have been lost, but the available legacy reports are assembled here as they contain the seeds and ideas for most of the recent nuclear energy developments and innovations, including those now going under the term "Generation IV".

The archive contains reports produced in the following countries:
Australia, Austria, Belgium, Canada, Denmark, Finland, France, Germany, Italy, Japan, the Netherlands, Norway, Spain, Sweden, Switzerland, United Kingdom, USA, and the USSR.

The purpose of gathering this information is to preserve several original papers describing how ideas of nuclear development were born, discussed and realized, for those who are interested in history of science and technology or the young generation who wishes to get inspiration from the bold ideas developed when nuclear energy was still young.
