A comparison of HANARO operating perfomance of the year 2001 and 2002 and the codification of start-up and shutdown procedures

By using the amount of power generation, the delay hours in full-power arrival and those in shutdown as the parameters, the operation record of HANARO in the year 2002 was analysed and the results were compared with those for the year 2001. The amount of power generation in 2002 was 4852 MWD, which is larger than that of 2001 by 1082 MWD and is the highest in record after initial criticality. The delay hours in full-power arrival and the delay hours in shutdown was 3.56 and 2.49 hours for 2001, respectively. Those for 2002 were 0.29 and 0.38 hours. This quantitative and qualitative improvement is believed to be in debt to the following measures; 3 week plan for activities including maintenance and experiment, the reduction of fuel inspection amount and starting-up the reactor by one hour earlier than in 2001. As for the standardization of the time to execute HANARO start-up and shutdown procedures, the code names were assigned to the individual procedures and the work time were investigated. The data recorded by the operators during start-up and shutdown were statistically analyzed. The analysis results will be used for the standardization of start-up and shutdown procedures and it will be reflected in the procedure document
