ANNUAL REPORT OF THE JAPAN ATOMIC ENERGY RESEARCH INSTITUTE FOR THE FISCAL YEAR ENDING APRIL 1961

Technical Report · Wed Oct 31 04:00:00 EST 1962

OSTI ID:4817183

The annual report describes the activities of the Institute in 14 chapters: reactor development, plant construction, operation of research reactors, nuclear engineering, physics, chemistry, uses of radiation, health physics, etc. JRR-2, a CP-5 type reactor which reached criticality in October 1960 is discussed; this reactor started operating at a power of 1 Mw in March 1961. The contract of JPDR (Japan Power Demonstration Reactor) was signed in August 1960; it is designed for a maximum electric output of 12.5 Mw. Assembly of graphite in JRR-3, the first Japanese-built reactor with a power rating of 10 Mw, was recently completed. Continuing the efforts in the field of reactor development, a semi-homogeneous critical assembly became critical, an aqueous homogeneous critical assembly is almost ready for fuel loading and preliminary experiments were carried out on a fast reactor and on magnetohydrodynamic methods of electric power generation. Construction of a 20-Mev linear accelerator was completed; in addition, a 3.5-Mev Van de Graaff generator, a hot-cave unit for fuel reprocessing work, a plutonium research facility and a radioisotope production plant are under construction at present.
