한국원자력연구원에 반입된 사용후핵연료에 대해 최근 대전 지역 정가와 시민단체 등이 이송 과정, 보관 은폐, 규정 위반 등의 문제를 제기하며 핵연료 반입 중단과 반출을 촉구하고 있다. 그 동안 한국원자력연구원이 수행해온 사용후핵연료의 이송, 보관 및 연구 개발, 그리고 이와 관련한 정보 공개 사항 등을 QA 방식으로 종합했다.

2008년부터 청약제도가 실수요자 중심으로 개편된다. 이에 따라 주택산업연구원은 지난 7월 건설교통부 주관하에 실수요자 중심의 주택청약제도 개편 방안에 대한 공청회를 개최했다. 이번 공청회에서는 장성수 주택산업연구원 선임연구위원이 '주택청약제도 개편방안' 이라는 주제로 발표했다. 실수요자 중심의 주택 공급과 보다 합리적인 주택청약제도를 제안한 장성수 선임연구위원의 발표 내용을 살펴본다.

Objectives: This study evaluated occupational exposures to noise and heat stress during routine non-outage works in three coal-fired power plants in the Republic of Korea. Methods: The data were collected during the summer of 2020. Full shift noise exposure of 52 workers were measured using noise dosimeters. Heat stress of 16 worksites were measured for 70 minutes using wet-bulb globe temperature monitors. Results: The noise dosimetry results revealed time-weighted averages that ranged from 47.5 to 88.9 dBA. 2 out of 52 noise measurements exceeded 85 dBA. Based on the arithmetic mean, the coal service group showed the highest level at 80.2 dBA by job tasks. Noise exposures exceeding 85 dBA were measured in the coal service and plant operator group. Heat stress index measurements ranged from 20.3℃ to 37.2℃. 1 out of 9 indices measured in coal facilities and 4 out of 7 indices measured in boiler house exceeded 1 hour TWA during moderate work. Heat stress indices measured from boiler houses were significantly higher than those measured from coal equipment. Conclusions: The results show that overexposure to noise and heat stress may be encountered during routine non-outage work activities in coal-fired power plants. Appropriate actions should be taken to reduce future health outcome from occupational exposure to noise and heat stress in the industry.

The rotorcraft engine gearbox transmits the power generated by the turboshaft engine to the rotor by reducing the rotational speed and increasing the torque. The core of the rotorcraft engine gearbox is lightweight performance, which requires maximum weight reduction within the range that meets various requirements and constraints. Therefore, lightweight design through gear macro geometry optimization is necessary. In this study, gear macro geometry optimization was performed to reduce the weight of a rotorcraft engine gearbox. NSGA-III was used for the optimization, resulting in a combination of the gear ratio and macro geometry that minimizes the weight of the total gear. In addition, the safety factor of the gears satisfied the given conditions.
