JRR-3 operated by Japan Atomic Energy Agency (JAEA) is 20 MW grade research reactor for widely used for various academic research and industrial applications in many fields from utilization of internal irradiation to utilization of neutron beam. Although JRR-3 has not been operated due to respond to the new regulation standard established after the Great East Japan Earthquake of March 11, 2011, JRR-3 will resume operation in October 2020. This article reports neutron utilization such as various kinds of reactor irradiation, prompt gamma-ray analysis, neutron radiography and neutron residual stress analysis, and the efforts of the JRR-3 user 's office aiming for a one - stop office.

Times Cited Count:4 Percentile:32.95(Instruments & Instrumentation)The methodology to derive cross section data from measurements in a cold neutron beam was studied. Mostly, capture cross sections at thermal energy are derived relative to a standard cross section, and proportionality between the standard and the measured cross section is often assumed. Due to this assumption the derived capture cross section at thermal energy can be biased by more than 10%. Evidently the bias depends on how much the energy dependence of the cross section deviates from a direct proportionality with the inverse of the neutron speed. The effect is reduced in case the cross section is not derived at thermal energy but at an energy close to the average energy of the cold neutron beam. Nevertheless, it is demonstrated that the bias can only be avoided in case the energy dependence of the cross section is known and proper correction factors are applied. In some cases the results can also be biased when the attenuation of the neutron beam within the sample is neglected in the analysis. Some of the cross section data reported in the literature suffer from such bias effects.

The fundamentals and applications on the neutron imaging technique, volume visualization and 3D measurement by the neutron 3D-CT technique and the most advanced imaging technique by using pulsed neutrons were reviewed in this paper. Visualization and measurement of the inside mortaring car engine is one of the industrial applications on the neutron imaging technique. This technique was also applied for visualization and measurement of the multiphase plow applications. The 3D visualization technique has been used for the concrete research etc. The pulsed neutron imaging techniques developed for J-PARC have made possible element-selective imaging and metallographic structure imaging which were impossible by the traditional techniques. Newly providing pulsed neutron imaging facilities for common use is also introduced briefly.

Times Cited Count:11 Percentile:61(Chemistry, Analytical)By combining neutron activation analysis with multiple -ray detection, we have proved better sensitivity and resolution for the trace element analysis than the ordinary single -ray detection method. We now try to apply the multiple -ray detection method to the prompt -ray analysis (PGA). We have established a new cold neutron beam line for PGA in Japan Research Reactor, JRR-3M, at Tokai establishment of Japan Atomic Energy Research Institute(JAERI). It consists of a beam shutter, a beam attenuator, a -ray detector array, a sample changer, and a beam stopper. We construct a high-efficiency -ray detector array specially designed for this purpose. Its performance has been evaluated with the Monte Carlo simulation code, GEANT 4.5.0.

Times Cited Count:9 Percentile:52.57(Chemistry, Analytical)The recommended k factors for 81 -lines of 24 elements, which are useful for neutron induced prompt -ray analysis (PGA) and are not influenced by neutron spectrum difference, were obtained from the k factors measured with the cold and thermal guided neutron beams of JRR-3M by statistical calculation. The prompt -ray emission probabilities were derived from the recommended k-factors using atomic weight, isotopic abundance and thermal neutron cross-section of other nuclear constants consisting the k factors, for which one can obtain accurate data. The derived -ray emission probabilities for the light elements (H to Ca) well agreed within 10% with those of the ENSDF, which reflect recent data, which the agreements for heavy elements (Ti to Pb) were 40% with those of the ENSDF, which are still composed of old data.
