This study is to develop a mobile type environmental radiation measurement system for emergency response or environmental radiation monitoring of local governments near nuclear facilities. A mobile radiation measurement system can monitor radiation by field beyond the spatial constraints of a fixed environmental radiation monitor. If installed in local government infrastructure such as public transportation, environmental radiation can be monitored without additional manpower and measurement work. In addition, it is designed to enable monitoring and measurement of radiation from low to high doses as well as the environment in preparation for radioactive disasters such as nuclear power plant accidents. It is expected that this system will be utilized not only in normal times but also in the event of a radiation accident to improve the disaster prevention capabilities of local governments.

병원이나 요양원과 같은 시설에서 화재 등 비상 상황시 거동이 불편한 재난약자를 신속하게 대피시키기 위한 대안 설비의 필요성이 제기되어 왔다. 본 연구에서는 재난시에 사용할 수 있는 비상 엘리베이터를 실내에 설치하기 어려운 경우에 대안으로 설치할 수 있도록 침상이나 탑승기를 하강시키는 새로운 방식의 전달식 피난 장치를 제안하고자 한다. 개별 층별로 독립적인 피난이 진행될 수 있도록 하였으며, 의료용 침상이나 탑승기 등과 같은 중량물의 안정된 전달 구조를 확보하기 위하여 각 부품에 요구되는 기능과 기계적 강도도 검토되었다.

This research project is a program promoted to seek diversification of domestic radioactive waste analysis institutions, and seeks public development, win-win cooperation, and cooperation between the entrusted institution and the entrusted institution. Accordingly, the entrusted institution established a standard analysis procedure for establishing a quality control system for radioactivity analysis, establishing a radiation control zone, obtaining KOLAS accreditation, and performing proficiency tests, which are the performance ranges requested by the entrusted institution, and intersecting the radioactive isotope waste generated at the actual site. Verification was performed to confirm the analysis quality. In addition, facilities and equipment for radioactivity analysis were supplemented and expanded, and the basic technology foundation and technical skills were secured through securing professional technicians and education/training. It is judged that the entrusted institution will contribute to securing radiation safety through the smooth execution of treatment, disposal, and transportation through value creation and analysis of radioactive waste generated by radioactive isotope-using institutions (research institutes, hospitals, industries, etc.) by succeeding in this research project do.

Factors affecting RTDs of two ideal steady-state flow reactors were investigated. A continuous stirred tank reactor (CSTR) and a plug flow reactor (PFR), were used for this study. The mean residence time of the NaCl tracer on a CSTR generally decreases with increasing agitation speed. However, it increases at 600 rpm agitation speed because of forming stagnant region in the reactor. For the PFR, the mean residence time decreases with increasing liquid velocity and decreasing the length of PFR, and correlations between these parameters and axial dispersion coefficient in the axial dispersion model (ADM) were obtained.

In this study, for the measurement of 3H(tritium) radioactivity concentration, a study was conducted on whether the type of cocktail and the material of the vial had an effect on the measurement before liquid scintillation counter measurement on HTO-type samples that had undergone physical and chemical pretreatment. As a result of the study, the efficiency according to the type of cocktail was higher in Ultima Gold LLT than Ultima Flo-AP cocktail with polyethylene (1.49%), glass (5.10%), and teflon (6.58%), respectively. Regarding the effect according to the type of vial, the efficiency and SQP(E) of both Ultima Gold LLT and Ultima Flo-AP showed the highest values in the order of teflon, polyethylene, and glass.

The multi-component ceramic proton conductor, BaZr(Y)O₃-SiO₂-TiO₂-ZrO₂ (BZY-STZ) and LaPO₄-SiO₂-TiO₂-ZrO₂ (LP-STZ), were synthesized by micro-emersion and sol-gel technique. The characterization of proton conductors were carried out using X-ray diffraction(XRD), thermogravimetric analysis(TGA), differential thermal analysis(DTA), impedance analysis. The proton conductors indicate the possibility of application for the intermediate temperature up to 700?C.
