SYSTEM FOR ANALYSING PROBABILISTIC SAFETY ASSESSMENT OF SUCCESS CRITERIA IN NUCLEAR POWER PLANT AND METHOD THEREFOR

摘要

PURPOSE: A system and a method for analyzing the success criteria of probabilistic safety assessment in a nuclear power plant are provided to analyze the success criteria of system lines and operator action time in probabilistic safety assessment by analyzing the accident sequence of main system lines in a nuclear power plant with thermal-hydraulic analysis codes, thereby assessing reliability thereof. CONSTITUTION: An input part(100) indexes event tree data including accident scenarios. An accident sequence selecting part(200) selects accident sequences and draws the accident sequences on the core damage of system lines based on the event tree data. An analysis part(300) defines information on safety action details as the titles of the event tree to draw the accident scenarios to thermal-hydraulic analysis codes according to the success or failure of each title. [Reference numerals] (100) Event tree data index; (300) Thermal-hydraulic analysis(MAAO4); (400) Outputting information on the result of an accident analysis; (AA) Taking a measure by an operator?; (BB) Generating accident sequence selection information and extracting the result of the measure by the operator; (CC) Generating accident sequence selection information
