平成17年度における研究炉(JRR-3, JRR-4)での実験利用,照射利用を行った利用者(原子力機構外も含む)からの成果の提出を受け、これを取りまとめたものである。

In the fiscal year 2005, The research reactor JRR-3 was operated 7 cycles (cycle operation : 26days/cycle) for utilization sharing of the facility. And JRR-4 was operated 37 cycles (daily operation : 137 days). JRR-3 is used for the purposes below; (1) Experimental studies such as neutron scattering, prompt -ray analyses, neutron radiography (2) Irradiation for activation analyses, radioisotope (RI) productions, fission tracks (3) Irradiation test of reactor materials etc. JRR-4 is used for the purposes below; (1) Medical irradiation (Boron Neutron Capture Therapy : BNCT) (2) Prompt -ray analyses (3) Sensitivity measurement of radiation detectors (4) Experiment in the nuclear reactor training (5) Practice of Reactor operation (6) Irradiation for activation analyses, RI productions, fission tracks etc. The volume contains 100 activity reports, which are categorized into the fields of neutron scattering (9 subcategories), neutron radiography, neutron activation analyses, RI productions, prompt -ray analyses, and others submitted by the users in JAEA and from other organizations.
