1. A population estimation method performed by a population estimation device, the method comprising:
storing location information of a plurality of nuclear power plants;
predicting a multi-unit accident occurrence point based on information on a plurality of single units respectively associated with the plurality of nuclear power plants, and
displaying the multi-unit accident occurrence point on a first user interface of the population estimation device, the first user interface implemented using a map application programming interface (API) of an external map service interacting with the population estimation device,
wherein predicting the multi-unit accident occurrence point comprises:
selecting a weight value for each of the plurality of nuclear power plants based on at least one of a power output of a respective nuclear power plant of the plurality of nuclear power plants, a discharge amount of a respective nuclear power plant of the plurality of nuclear power plants, and a population associated with a respective nuclear power plant of the plurality of nuclear power plants;
determining the multi-unit accident occurrence point based on the selected weight value for each of the plurality of nuclear power plants,
calculating an area of each administrative region using administrative region data based on geographic information system (GIS) data; and
modeling a radiation grid of a polar coordinate system composed of a plurality of sectors for performing safety evaluation of the plurality of nuclear power plants,
wherein a grid of the polar coordinate system is modeled to automatically generate a set of sectors having coordinate values of the polar coordinate system based on setting information including a center point, an orientation, and an interval of the grid input through a second user interface for inputting the setting information by a user,
wherein the method further comprises:
storing at least one point which is used as the setting information more than a predetermined number of times; and
automatically designating the stored at least one point as the center point of the setting information, and
wherein the displaying comprises:
acquiring analysis data for the sectors from an external system, the analysis data including concentration data and radiation dose data for each atmospheric halide;
converting the acquired analysis data into formatted data of a data model compatible with the population estimation device; and
distinguishably and visually displaying, on the first user interface implemented using the map API, the concentration data and radiation dose data for each atmospheric halide based on the formatted data using different colors.
