In Korea, Kori Unit 1 and Wolsong Unit 1, have been permanently shut down in 2017 and 2019, and more nuclear power plants are expected to be permanently shut down after continued operation successively. Spent fuel has been generated during operation and stored in spent fuel pools. Due to the expected saturation of spent fuel pools within the next several decades, transportation of a huge amount of spent fuel is anticipated to interim storage facilities or final disposal facilities, even though the specific location is not decided. The U.S. Nuclear Regulatory Commission (NRC) states that every environmental report prepared for the licensing stage of a Pressurized Water Reactor shall contain a statement concerning risk during the transportation of fuel and radioactive wastes to and from the reactor. Thus, the licensee should ensure that the radiological effects in accidents, as well as normal conditions in transport, do not exceed certain criteria or be small if cannot be numerically quantified. Specific conditions that a full description and detailed analysis of the environmental effects of transportation of fuel and wastes to and from the reactor are exempted are specified in 10 CFR Part 51. Since there are no official requirements for radiological dose assessment for workers and public during the transportation of spent fuel in Korea, the margin when applying the U.S. regulatory criteria to the environmental impact assessment during the transport of spent fuel generated from domestic nuclear power plants is evaluated. A different approach would be needed due to the difference in the characteristics of spent fuel and geographical features.

In this study, we measured the concentration of Particulate Matter (PM10), Formaldehyde (HCHO), and Total Bacteria Count (TBC) at three facilities: elderly care centers, day care centers, and postnatal care centers located in the cities of Seoul, Sejong, Daegu and Ulsan from January 1, 2012 to December 31, 2015. PM10 concentration was the highest in the day care centers and HCHO concentration was the highest in the postnatal care centers. TBC concentration was the highest in the day care centers. Comparing the different cities, PM10 concentration was the highest in Sejong, HCHO concentration was the highest in Seoul, and TBC concentration was the highest in Daegu. This study is expected to be helpful in preventing damage to health from the contaminated indoor air at sensitive facilities, and can be used as basic data for indoor air quality management.

The objectives of this study were to analyze the characteristics of odor in the major facilities of a fishery industrial complex using the air dilution olfactory method and the instrumental analysis method. The results indicate that although the limit of dilution to threshold (D/T) ratio in the major facilities is not regulated by the Odor Emission Standard, the mean (D/T) ratio over than 3,000 which is higher than the limit in the outlet of industrial area 3 times was found at three sampling sites. In the case of the concentration of the malodorous compounds, ammonia concentration is higher than any other odor compounds. The methyl mercaptan, n-Butyric acid and hydrogen sulfide as the main pollutants are confirmed by the odor quotient (OQ). In our study, it is showed a moderately good correlation between the (D/T) ratio and the sum of OQ. By this result, we can estimate the odor characteristics and evaluate the potential impact of each odor compound. In addition, we consider that it will affect the people"s normal life and even cause for complaint around the boundary area by the diffusion of odor.

2018년도 시설물의 안전 및 유지관리에 관한 특별법이 전면 개정됨에 따라 제1종 및 제2종시설물 중에서 사회기반시설물 범주에 해당하는 시설물(이하 ‘성능평가 대상시설물’)에 대해 성능평가를 실시하도록 하여 성능등급을 지정하도록 하고 있다. 본 연구에서는 성능평가를 통해 도출된 시설물별 성능등급을 시설물 유형별로 성능등급으로 분석할 수 있는 방법을 도출하고 그 결과를 개선할 수 있는 방안에 대해 고찰하였다.

Youth Training Facilities is a facility used for youth training activities. Youth Training Facilities is a facility that could be vulnerable to accidents. The purpose of this study is to minimize any accidents through analysing previous inspection data. Should avoid accidents that may occur during training activities through real-time management of the facility.

Water samples from several wastewater treatment plants and two industry drains in Gyeongsangbukdo were investigated for concentration levels of micropollutants. Samples were taken totally four times from May to November of 2008 and tested for seven factors including pesticide, 1,4-Dioxane and Perchlorate which had been big issues for Nakdong river because of their contaminations. As results, 2,4-D, Alachlor, and BEHA were not detected while BEHP was detected at some sampling sites. 1,4-Dioxane and Perchlorate were also detected in wide ranges from several sampling sites. Therefore, continuous supervising and monitoring systems needed to be invested for proper management for micropollutants since those micropollutants could affect human health and aquatic system with low concentration levels.
