Times Cited Count：2 Percentile：35.75(Nuclear Science & Technology)One of the major subjects for evaluating the corrosive conditions in the PWR primary coolant was to determine the optimal hydrogen concentration for mitigating PWSCC without any adverse effects on major structural materials. As suitable procedures for evaluating the corrosive conditions in PWR primary coolant, a couple of procedures, i.e., water radiolysis and ECP analyses, were proposed. The previous article showed the radiolysis calculation in the PWR primary coolant, which was followed by an ECP study here. The ECP analysis, a couple of a mixed potential model and an oxide layer growth model, was developed originally for BWR conditions, which was extended to PWR conditions with adding Li
(Na) and H effects on the anodic polarization curves. As a result of comparison of the calculated results with INCA in-pile-loop experiment data as well as other experimental data, it was confirmed that the ECPs calculated with the coupled analyses agreed with the measured within 
100mV discrepancies.

Times Cited Count：1 Percentile：0.00(Nuclear Science & Technology)We have developed a void reactivity evaluation method by using modified conversion ratio measurements in a light water reactor (LWR) critical lattice. Assembly-wise void reactivity is evaluated from the "finite neutron multiplication factor", 
, deduced from the modified conversion ratio of each fuel rod. The distributions of modified conversion ratio and on a reduced-moderation LWR lattice, for which the improvement of negative void reactivity is a serious issue, were measured. Measured values were analyzed with a continuous-energy Monte Carlo method. The measurements and analyses agreed within the measurement uncertainty. The developed method is useful for validating the nuclear design methodology concerning void reactivity.

In the FNCA Coordinator Meeting held on March 2002, "Survey of the Basic Data on HRD in the Nuclear Field" was proposed as the first step for developing the HRD strategy by producing the quantitative data on HRD in nuclear field. The first results were reported during the 2002 FNCA Workshop on HRD held on October 2002. The survey results were analyzed in 2003, and summarized as "Summary of the Survey Data". It was reported during Workshop in 2003. The report consists of the updated data until early 2004 of the summary data.

The FNCA 2002 Workshop on the Utilization of Research Reactors, which is the eleventh workshop on the theme of research reactor utilization, was held in Jakarta and Serpong, Indonesia from January 13 to 17. This workshop was executed based on the agreement in the third Coordinator's Meeting of Forum for Nuclear Cooperation in Asia (FNCA) held in Tokyo, March 2002. The workshop consists of two groups under the theme of the following fields; 1) Tc-99m Generator Technology, 2) Neutron Activation Analysis. The total number of participants for the workshop was 88 people from 8 countries; China, Indonesia, Korea, Malaysia, the Philippines, Thailand, Vietnam and Japan. This report consists of 8 papers from the plenary session, 10 papers for Tc-99m Generator, 10 papers for Neutron Activation Analysis and a summary report.

This report summarizes conceptual design study up to March, 2003, relevant to the Materials & Life Science Experimental Facility construction which is one of the major user facilities to be constructed under the J-PARC project of High Intensity Proton Accelerator. The first chapter corresponds to the design manual, and the followings stand for the technical parts giving the design principle and detailed results for the studies. As the project is evolving day by day, some of studies have been advanced since the moment of this summary in one hand, and some of parts are close to final stage of design. Including those, more comprehensive and updated version of the technical designs are to be reported accordingly.

The Human Resources Development (HRD) Project in the framework of the Forum of Nuclear Cooperation in Asia (FNCA) is a very effective mechanism under which the representatives from neighboring 8 countries gather in one place to discuss and exchange information on HRD in nuclear field. Following major tasks are being carried out, (1)Investigate the needs on human resources development in each country and the mutual support activities such as information exchange utilizing internet homepages and exchange of textbooks have been started. More efficient utilization of the existing personnel exchange programs is also being planned. (2)Assistance in the formulation of HRD strategy in each country. (3)Cooperative actions such as exchange of information on the recruitment of young generation to nuclear field, which is an issue common to all member countries.None of these tasks can yield visible results easily. HRD takes much time and effort to build mutual understanding, cooperative relationship and obtain the results together. There is no quick medicine for HRD.
