Abstract
The Atomic Energy Research Institute, the predecessor of the Japan Atomic Energy Research Institute, was established on Nov. 30, 1955, and the Tokai village in Ibaragi Pref. was selected as the site of the Institute on Apr. 6, 1956. The Japan Atomic Energy Research Institute was established on June 15, 1956, and the construction of JRR-1 and other facilities started on Aug. 10, 1956.
Today, three years after the start of construction in the quiet Tokai village, many facilities of the Institute have been completed and the total building area covers more than 30, 000m2, where a staff of 700 is already working. During the construction, the principal aim was to make facilities adequate for nuclear research.
Particularly careful measures were provided for radiation protection to research workers and the general public. The problems of radiation shielding air tight construction and ventilation for radio-active fission products etc. have been studied and the results were applied in designing the facilities.
In the present paper, various aspects of the site, plan of construction and the outlines of the principal building facilities such as JRR-1, synthesis laboratory, JRR-2, 10kc 60Co and Linac radiation facilities, Hot Lab. and JRR-3 are described.
