Info

Regional Basic Professional Training Course (BPTC) on Nuclear Safety power reactors in operation, and monitors the operational status of the individual operating reactors every 10‐20 seconds on a real time basis. Furthermore, in the case of a radiological accident, the system is utilized for an analysis of the accident situation, prediction of the post‐accident processes, and the consequences and estimation of the source terms. 2.2.1.1. System Functions a) Collects and analyzes approximately 200‐400 of critical safety parameter values for the individual nuclear power reactors in operation. b) Transmits the data every 10‐20 seconds using a leased line for every reactor in operation. c) Classifies the collected safety parameter values according to the critical safety function. d) Remains connected to all the reactors in operation at the four nuclear power plant sites. Classification Major Functions Operation Condition Review of Parameter Values ‐ Indicates the critical parameter values and status of the major equipment or components of the reactor operations and control system on a real‐time basis. ‐ Consists of the overall conditions of a nuclear power plant; the sub‐ criticality of the core, the core cooling, the heat removal sources, the coolant integrity, the coolant inventory, the containment vessel integrity, as well as the radiation management, the secondary side, the auxiliary system, and the operations condition of the safety systems. ‐ Classifies the safety parameter values collected in real‐time into specific groups, and interprets the safety parameter values with an overall comparison of the individual parameters as a trend. ‐ Posts the power output status of all the nuclear power plants. ‐ Manages and controls the alarm set point values of the safety parameter values as well as the history of these parameter values. ❙ 1128 ❙
Classification Major Functions Technical Tree Logic Tree for Source Term Analyses ❙ 1129 ❙ AtomCARE ‐ Identifies the occurrences of the problems in the individual systems derived from a sequential flow analysis of the operational parameter values. ‐ Interprets the status of an individual system of a nuclear power plant (classified by green, yellow, orange and red) by applying the safety parameter values collected in real‐time to the pertinent logic algorithm for the system. ‐ Estimates the amount of radioactive materials released outside the nuclear power plant site during an accident by predicting the radiological accident at a nuclear power plant from an analysis of the major operational parameter values of that particular nuclear power plant. ‐ Consists of the individual logic tree per content such as the occurrences of the abnormal events, S/G fine tube breaks, amount of coolant leakage, leakage in the nuclear fuel gap, core melting, container damage and breakage, radioactive materials released through the stack, and unexpected radiation releases, and other conditions. 2.2.1.2. Classification of the Critical Safety Functions Screen of the Overall System Interprets the overall operational status of a nuclear power plant operation by displaying the power output of the reactor, the power output of the generator, the average temperature of the reactor core, the coolant water level of the reactor vessel, the pressure level of the pressurizer, the pressure level of the containment building and the radioactivity level of the containment building. Maintenance of Reactor Shutdown Status Interprets the shutdown condition of a reactor by displaying the power output values of the reactor, the power output values of the nuclear power output monitor with an overall output range, the power output values of the nuclear power output monitor with an intermediate range, the power output values of the nuclear power output monitor with a source range, and the positions of the shutdown rods.
