Quality control of in-service inspection in nuclear island
During the refueling outages of PWRs, ISI in nuclear island will contribute to find the equipment degradation generated during its normal operation, which can lay a foundation for the safe operation of nuclear power plant. ISI of nuclear island equipment was carried out from two sides: implementation and management. A detailed process of nondestructive testing and quality control during the preparation stage, project implementation stage and postsession integration stage was presented in accordance with the project procedures. Main responsibilities of quality control personnel stand out in the whole process.
Study and Application of Information Management System for Government-Invested Construction Projects
Government-invested construction projects have their own characteristics, and effective management can be achieved only by adopting corresponding appropriate management approaches. The characteristics of government-invested construction project management and corresponding serious problems existed in present management are analyzed and summarized at first. Secondly, the countermeasures to above problems are put forward. Then, an information management system framework for government-invested project management is proposed on the basis of the foregoing work. This framework can realize the fusion of project information management system and E-government system and achieve the institutionalization, standardization, informatization and lifecycle management for government-invested project by means of multiple modernized information technologies and professional software. Finally, the development and application of the developed information system validate the effectiveness to promote the management level of government-invested construction project. The work involved in this paper can provide reference for the management of other similar construction projects.
Evaluation Model for Information Systems Benefits in Construction Management Processes
The importance of information systems (IS) implementation in construction management has grown rapidly, and therefore, a more practical method for IS planning is required. Prioritizing the construction management processes in which IS will be implemented is one of the key processes in IS planning, and for the prioritization purpose, the benefits of IS implementation must be examined. This research suggests an evaluation model for IS benefits in construction management processes. The model is based on the evaluation of IS implementation benefits at the construction management task level, and it is postulated that the benefits are composed of the effect and possibility of IS implementation. The research suggests four basic measures as the fundamental evaluation criteria and represents an overall evaluation process in the model. A case study is performed to validate this model via a statistical analysis, and the result shows that the four measures can explain at least 58% of the variance of expected benefit from IS implementation. The contributions of this paper can be summarized in two aspects. First, researchers may further enrich the understanding of IS benefits realization mechanism with the factors. Second, industry practitioners may use the model in their IS planning task.
