PID(Proportional, Integral, Derivative) controller is one of the most used process controllers in nuclear power plants. The optimized parameter setting of process controller contributes to the stable operation and efficiency in the operating nuclear power plants. PID parameter setting is tuned when new process control system is established or process control system is changed. It is a burdensome work for I&C(Instrument and Control) engineers to tune the PID controller because it requires a lot of experience and knowledge. When the plant is in operation, inadequate PID parameter setting can be the cause of the unstable process of the plant. Therefore the results of PID parameter setting should be compared, simulated, verified and finally optimized. The practical PID tuning methods used in process controller are tuning operation calculation(Ziegler-Nicholes, Minimum TIAE, Lambda, IMC), exclusive tuning program based on computer and Matlab application. This paper introduces the various tuning methods and suggests an optimized PID tuning process in the operating nuclear power plants.

Objective: This study is to investigate and observe what essential procedures are for operators in the main control room (MCR) of APR1400 Power plant to share performance information when performing the procedures. In APR1400, the procedures that need to be shared for the performance information between operators are determined in advance when they are prepared. Background: It is important to share procedure execution information between operators to reduce human errors in MCR. CPS (Computerized Procedure System) makes it possible in APR1400, but all the procedures are not designated to be shared. Therefore this study is to find out what procedures need to be essentially shared between operators with CPS in APR1400 MCR. Method: There was the ISV (Integrated System Validation) for SKN unit 5 in the Shinkori units 5&6 simulator in Busan for the 3 weeks from August to September in 2021. During the ISV, 12 scenarios were performed for validation of MCR HFE and the scenarios consisted of dozens of operating procedures. And the operators, who were the subjects, performed the scenarios. Whenever each scenario finished, we found out the operating procedures that need to be shared through expert observation, surveys and interviews with operators. Results: According to the result of the observation, the surveys and interviews, the operating procedures that need to be shared essentially included all AOPs (Abnormal Operating Procedures) as well as all EOPs (Emergency Operating Procedures). Conclusion: For reducing human errors and enhancing operator’s performance in MCR, all the EOPs and AOPs in APR1400 MCR need to be shared between the operators with CPS. Application: The results of this study will be applied to operating procedures for SKN units 5&6.
