Secondary cosmic-ray neutron-induced soft errors have been recognized as a serious problem affecting the reliability of microelectronic devices. Our developed Multi-scale Monte Carlo simulator called PHYSERD is a reliable code for analysis of soft error. However, PHYSERD takes long computational time to calculate processes of collecting charges because event-by-event technology computer-aided design (TCAD) simulation is time consuming. In this study, the multiple sensitive volume (MSV) model is adopted to estimate collected charge. Secondary cosmic-ray neutron-induced soft errors in an NMOSFET are analyzed based on the MSV model using PHITS. The results are compared with those obtained by PHYSERD based on event-by-event TCAD simulation and by single sensitive volume (SSV) model using PHITS. It is found that PHITS+MSV provides approximate SERs in a shorter time than PHYSERD. Furthermore, PHITS+MSV reproduces SERs and collected charges more accurately than PHITS+SSV by considering the spatial dependence of the charge collection efficiencies.

Since a chloride ion is assumed to be one of the predominant solutes dissolved in groundwater, a study of the radiolysis of chloride ion and oxychlorides in aqueous solutions has been carried out in order to obtain the reliable and predictable data for the understanding the radiation induced reactions taking place in groundwater, relevant to the geological radioactive waste repository. The rate constants of the reactions between water decomposition products and different oxychlorides were determined by means of pulse radiolysis and laser photolysis methods. By using the techniques of photometry and ion-chromatography, the products formed by irradiation were analyzed and the overall reactions were summarized. After the comparison between the simulation and the experimental results, the redox reactions of the oxychloride compounds in aqueous solution were summarized and future work to be done has been pointed out.

In order to keep the integrity of the repository of the radioactive high level waste, it is inevitably important to grasp and clarify the chemical conditions of the groundwater and it is highly required to evaluate the radiation induced chemical effect in groundwater. In the present report, a database has been constructed from the literatures in the field of radiation chemistry published up to now, as a first step of the evaluation of the radiation induced chemical reactions and their rate constants in aqueous solutions containing chemical species, which are normally present in groundwater. On the basis of the database, simulations for several typical aqueous solutions have been carried out, and both further reactions to be investigated and additional experiments to be done in future have been pointed out. It is concluded that experimental data is highly expected to be accumulated and compared with simulation.
