Dose Assessments

Abstract Accidentally released radionuclides are dispersed into the environment and cause human exposure through various pathways. Concerns about radiological impacts of a possible Nuclear power plant (NPP) accident in neighboring countries, especially in China, are increasing in Korea. Dose assessments for the hypothetical nuclear accidents in Korea (Hanbit and Wolsong NPPs) and China (Tianwan NPP) were conducted using the developed Korean code system. The results show that there is a possibility that a Tianwan NPP accident could have a slightly greater or similar impact on certain parts of Korea compared to accidents occurring at domestic NPPs, and could affect Korea within a few days of the accident. This research is expected to be used as basic material for preparing against nuclear accidents in neighboring countries.

Due to the increase in energy demand, many countries suffer from energy poverty because of insufficient and expensive energy supply. Plans to use alternative power like nuclear power for electricity generation are being revived among developing countries. Decisions for installation of power plants need to be based on careful assessment of future energy supply and demand, economic and financial implications and requirements for technology transfer. Since the problem involves many vague parameters, a fuzzy model should be an appropriate approach for dealing with this problem. This study develops a Fuzzy Multi-Objective Linear Programming (FMOLP) model for solving the nuclear power plant installation problem in fuzzy environment. FMOLP approach is recommended for cases where the objective functions are imprecise and can only be stated within a certain threshold level. The proposed model attempts to minimize total duration time, total cost and maximize the total crash time of the installation project. By using FMOLP, the weighted additive technique can also be applied in order to transform the model into Fuzzy Multiple Weighted-Objective Linear Programming (FMWOLP) to control the objective values such that all decision makers target on each criterion can be met. The optimum solution with the achievement level for both of the models (FMOLP and FMWOLP) are compared with each other. FMWOLP results in better performance as the overall degree of satisfaction depends on the weight given to the objective functions. A numerical example demonstrates the feasibility of applying the proposed models to nuclear power plant installation problem.
