This paper is to represent the cross-border mobility of experienced Professional Engineers by establishing and maintaining an EMF International Register of Professional Engineers which is based on confidence in the integrity of national assessment system and a system of mutual recognition secured through continuing mutual inspection and evaluation of these systems. This paper would cover develop, monitor, maintain and promote mutually acceptable standards and criteria for facilitating the cross-border mobility of experienced Professional Engineers based on. Engineers Mobility Forum Agreement Sifted 25 June 2001, Thornybush. South Africa

지금까지의 CANDU 사고이력과 관련된 문제점을 살펴보면 핵연료 채널의 부적절한 설계 및 설치 그리고 부적절한 압력관 가동조건 등에 많은 문제점이 있었다. 이러한 의미에서 CANDU의 안전성은 압력관의 건전성으로부터 확보된다 하여도 과언이 아니다. 그러나 CANDU에서 차지 하는 중요성에 비추어 압력관의 사용환경은 매우 열약하다. 따라서 가동중 압력관 건전성 위협 요인에 대한 정기적인 검사, 시험 및 평가는 CANDU 안전성확보의 첫걸음이 된다. 특히 건전 성평가에 필요한 주요자료가 압력관 인출시험결과로부터 확보됨을 고려할 때 압력관 인출시험을 국내에서 수행할 수 있는 능력을 확보하는 것 또한 우리에게 부과된 과제라 할 것이다.

An analysis program for the evaluation of pressure vessel integrity under pressurized thermal shock (PTS) is developed. For given material properties and transient history such as temperature and pressure, the stress distribution is calculated and then stress intensity factors are obtained for a wide range of crack sizes. The stress intensity factors are compared with the fracture toughness to check if cracking is expected to occur during the transient. Using this program a round robin problem of PTS during a small break loss of coolant transient has been analyzed as a part of the international comparative assessment study. The allowable maximum reference nil-ductility transition temperatures are determined for various crack sizes.

In this study, the geometric modeling has been conducted for 2 models of lower end fitting of advanced LWR fuel using three-dimensional solid modeler, Solidworks. Then, the optimization and the three-dimensional stress analysis using the finite element method has been peformed. The evaluation for the mechanical integrity of 2 models has been peformed based on the stress distribution obtained from the finite element analysis.

The performance of a hammer/driving systems is a major factor which affects bearing capacity and integrity of installed piles. Hammer performance can be evaluated from the results of dynamic pile testing using Pile Driving Analyzer(PDA). By comparing the rated energy with measured maximum transferred energy(EMX), the energy transfer ratio(ETR) can be calculated. This paper based on the dynamic measurements of 442 cases in 130 piling projects and evaluated ETR according to the hammer types(hydraulic and drop hammers) and pile types(steel and concrete piles).
