Abstract

There is provided a method for decommissioning plan of nuclear facility includes receiving a plurality of decommissioning related information data, and determining whether error data is included in the plurality of decommissioning related information data based on a database which contains characteristic information and decommissioning plan information of a plurality of nuclear facilities. The method further includes analyzing a state of a decommissioning target facility by identifying the decommissioning target facility based on the plurality of decommissioning related information data and the database, wherein when the error data is included in the plurality of decommissioning related information data, said analyzing is performed by identifying the decommissioning target facility based on the plurality of decommissioning related information data from which the error data is excluded and the database. The method further includes designing a decommissioning plan of the decommissioning target facility based on the analyzed state.

First claim

What is claimed is:

1 . A method for decommissioning plan of nuclear facility, comprising:
receiving a plurality of decommissioning related information data; determining whether error data is included in the plurality of decommissioning related information data based on a database which contains characteristic information and decommissioning plan information of a plurality of nuclear facilities; analyzing a state of a decommissioning target facility by identifying the decommissioning target facility based on the plurality of decommissioning related information data and the database, wherein when the error data is included in the plurality of decommissioning related information data, said analyzing is performed by identifying the decommissioning target facility based on the plurality of decommissioning related information data from which the error data is excluded and the database; and designing a decommissioning plan of the decommissioning target facility based on the analyzed state.

2 . The method of claim 1 , wherein the plurality of decommissioning related information data includes information on a structure or equipment included in the decommissioning target facility.

3 . The method of claim 2 , wherein the information on the structure or the equipment includes at least one of information on a history of design, construction and heat output of the nuclear facility, information on a weight, a size, an installation location, and used materials, information on a design change of the nuclear facility, and information on a history of an accident, a cause of the accident, and an action for the accident in the nuclear facility.

4 . The method of claim 2 , wherein said determining whether error data is included in the plurality of decommissioning related information data comprises:
determining that the error date is included when there is data that is not linked to a linking structure which defines a connection relationship between the received data based on the characteristic information of the plurality of nuclear power facilities.

5 . The method of claim 4 , wherein the characteristic information of the plurality of nuclear power facilities includes information on an available structure and an available equipment and a relevance between the available structure and the available equipment depending on a type of each of the plurality of nuclear facility types.

6 . The method of claim 1 , wherein the decommissioning plan information includes decommissioning technique information for each type of the plurality of nuclear facilities and information on laws and regulations for a nuclear facility.

7 . The method of claim 6 , wherein the decommissioning technique information includes at least one of radiation measurement technique, decontamination technique, cutting technique, waste treatment techniques, and site restoration technique.

8 . The method of claim 1 , wherein said analyzing the state of the decommissioning target facility comprises:
analyzing one of decommissioning site and environmental status of the decommissioning target facility, decommissioning work activity, comparison of the applicable decommissioning technique, radioactive waste management, environmental impact during decommissioning, safety of decommissioning, radiation protection, fire protection, and decommissioning cost based on the remaining data and the database; and determining a decommissioning technique to be used for decommissioning the decommissioning target facility to meet a predetermined criterion, wherein the predetermined criterion is designated in accordance with the laws and regulations for the nuclear facility.

9 . The method of claim 8 , wherein said designing the decommissioning plan comprises:
representing the analyzed state and the determined decommissioning technique in a hierarchical structure based on the database, the type of the decommissioning target facility, and the information on the structure and equipment of the decommissioning target facility; and outputting the analyzed state and the determined decommissioning technique represented in the hierarchical structure.

10 . An apparatus for decommissioning plan of nuclear facility, comprising:
a data receiver for receiving a plurality of decommissioning related information data; a discriminating unit for determining whether error data is included in the plurality of decommissioning related information data based on a database which contains characteristic information and decommissioning plan information of a plurality of nuclear facilities; an analyzing unit for analyzing a state of a decommissioning target facility by identifying the decommissioning target facility based on the plurality of decommissioning related information data and the database, wherein when the error data is included in the plurality of decommissioning related information data, the analyzing unit analyzes the state of the decommissioning target facility by determining the decommissioning target facility based on the plurality of decommissioning related information data from which the error data is excluded and the database; and a designing unit for designing a decommissioning plan of the decommissioning target facility based on the analyzed state.

11 . A computer-readable recording medium having a computer program stored therein for causing a processor to perform a method for decommissioning plan of nuclear facility, the method comprising:
receiving a plurality of decommissioning related information data; determining whether error data is included in the plurality of decommissioning related information data based on a database which contains characteristic information and decommissioning plan information of a plurality of nuclear facilities; analyzing a state of a decommissioning target facility by identifying the decommissioning target facility based on the plurality of decommissioning related information data and the database, wherein when the error data is included in the plurality of decommissioning related information data, said analyzing is performed by identifying the decommissioning target facility based on the plurality of decommissioning related information data from which the error data is excluded and the database; and designing a decommissioning plan of the decommissioning target facility based on the analyzed state.
