This study investigates the safety assessment of the potential for fretting-wear damages on steam generator (SG) U-tubes caused by foreign object in operating nuclear power plants. The operating SG shell-side flow field conditions are obtained from three-dimensional SG flow calculation using the ATHOS3 code. Modal analyses are performed for the finite element modelings of U-tubes to get the natural frequency, corresponding mode shape and participation factor. The wear rate of U-tube caused by foreign object is calculated using the Archard formula and the remaining life of the tube is predicted. Also, discussed in this study is the effect of the flow velocity and vibration of the tube on the remaining life of the tube.

2013년 이후로 산업안전보건법상 건설업 위험성 평가가 시행되었으나 법적 강제성이 없어 건설회사들은 이를 형식적으로 운용해 왔다. 또한 최근 산업안전보건법 전면개정, 중대재해 처벌등에 관한 법률 등으로 안전보건 의무를 강화하였으나 사고성 사망만인율은 정체되고 있는 것이 현실이다. 산업재해를 예방하기 위한 위험성 평가 계획이 적절하게 수립된다고 하더라도 해당 사업장에 종사하는 근로자가 위험성 평가의 내용을 이해하고 실행할 수 있어야 하며 이를 위해서는 해당 근로자를 참여하도록 하는 것이 중요하다. 본 연구에서는 이를 위해 건설업 위험성 평가 시 취약계층 근로자의 참여를 활성화할 수 있도록 현장 실태조사를 통해 문제점을 파악하고 효율적인 근로자 참여방안을 모색하고자 하였다.

Individuals who are vulnerable during disaster - including elderly, people with disabilities, children, pregnant women and etc - have a strong desire to protect themselves when disaster strikes since they are less capable to deal with the impact of disaster. Their experience and effort to keep them safe can be used as a resource to reduce the impacts of disaster not only for them but also for the community as a whole. Therefore, voluntary disaster management program will contribute to our society as a tool to respond effectively to disaster not only to meet the vulnerable's special needs but also to enhance community safety and public interest. This paper suggests a model that able "disaster vulnerable population" to take a leadership role in identifying risk and vulnerability factors, recommending disaster management strategy, and through that, contributing to enhance society's disaster plan. Therefore, this study aimed to surveyed individuals including "disaster vulnerable population" in order to assess the vulnerable's participation in disaster related volunteer work and surveyed associated institutions(volunteer centers, community centers) in order to research currently existing relevant programmes and the participation of "disaster vulnerable population" in such programmes. Also conducted focus group interview to explore voluntary program which will possibly integrate "disaster vulnerable population" into disaster management activities. As a result, three types of voluntary disaster management programs - education, public-relations, and activity - were suggested.
