Generation Activity

In order to gain more operational benefits, many nuclear power plants will intend to optimize the generation activity to increase generating capability factor, such as, shortening the refueling schedule by optimize the inspection strategy of relevant to SSCs (structure, system, component) during reactor shutdown. Therefore, this paper will introduce the research on the inspection strategy change based on risk-informed method, and provide detailed discussion on change of the RHR heat exchanger inspection strategy by employed the above mentioned method in one nuclear power plant. The result shows that the optimization of RHR heat exchanger inspection strategy meets all the consideration of the principles in risk-informed decision-making required by RG 1.174 and the optimization proposal is acceptable.

Abstract: The study was executed to get a quick calculation method for the design of equipment heat exchanger type shell and tube with a program shell and tube heat exchanger design. The purpose of this study was to obtain the results of the validation program shell and tube heat exchanger design of a condenser with power 4368.75 kW and the results of the evaluation program shell and tube heat exchanger design on the thermal design condensers nuclear power plant AP1000 PWR type. Input data into the program is done by inserting the parameters temperature, flow rate, physical properties and geometrical dimensions of the available designs of heat exchanger equipment specifications. Parameter for comparison of data can be obtained from the results of other calculations or experimental data. The results of comparison of the validation program shell and tube heat exchanger with condenser design calculations showed the highest difference found on Utube parameter equal to 1.3% lower than the design condition. This occurs because of differences in calculation between the program designed. The result evaluation of program shell and tube heat exchanger design toward the thermal design condensers nuclear power plant PWR type AP1000 obtained unknown parameters from the technical specifications.
