Isothermal System

The objective of COSINE (COre and System INtegrated Engine for design and analysis) project is to develop a software platform which is used for nuclear power plant design and safety analysis. The system code (SYST) is a part of COSINE code. In this paper, the mathematic model of accumulator is established. The model is based on following assumptions: nitrogen above liquid level in accumulator is represented in idea gas equation, water is modeled as an isothermal system. The model for liquid flow include inertia, wall friction, form loss, and gravity effects. Several cases were calculated under different conditions, and the results were compared with RELAP5. It shows that COSINE results agree well with RELAP5.

As a third-generation nuclear power plant design, construction of the Westinghouse AP1000 incorporates the characteristics of modular construction and the “Open-Top” lifting method, which results in many kinds of lifting operations, whose potential failure creates increased risk to key equipment and construction personnel. Lifting by its very nature is high risk. Based on traditional safety management practices utilized at the project, lift operation characteristics were analyzed, and procedures and processes developed to manage the risk. These developed aspects included: lifting operation procedures; a construction scheme review/approval process; work planning/risk mitigation; equipment inspections; personnel certification requirements; training; crew management; special inspections; lessons learned utilization; discipline management; emergency management; and safety culture development. The authors believe that the safety management approaches discussed in this paper can provide guidance in conducting safe lift operations in other nuclear power plant projects.
