Abstract

Abstract Remaining Useful Life (RUL) estimation has been extensively explored in recent years. RUL could be used in deciding the maintenance timeline or inspection interval for the Reaktor Serba Guna – G. A. Siwabessy (RSG-GAS reactor). RSG-GAS reactor is a pool-type research reactor (built by the Interatom Internationale of Germany) and has been operating for more than 30 years to date. This study aimed to propose a Weibull model to find the RUL estimation value of the distribution parameters of the mean time to failure (MTTF). Therefore, the RSG-GAS reactor would be higher safety, longer lifetime and higher reliability with a smaller failure rate including for the PA01-AP01 secondary pump. The research methodology is processing data collection and estimating the parameters of the Weibull model to determine maintenance timeline or inspection intervals based on the MTTF value in case the reliability has reached the targeted percentage. Results show that the RUL estimation has been obtained for the RSG-GAS reactor. In the implemented study, a maintenance timeline has been stipulated for the PA01-AP01 secondary pump (with the model of KSB and type of CPK-S350-400) for the reliability of 90% and RUL estimation of circa 29 days.

基于PA01-AP01二次泵的RSG-GAS反应器RUL估计Weibull模型

摘要剩余使用寿命(RUL)的估算是近年来研究的热点。RUL可用于确定Serba Guna - g.a. Siwabessy反应堆(RSG-GAS反应堆)的维护时间表或检查间隔。RSG-GAS反应堆是池式研究堆(由德国国际原子能机构建造)，迄今已运行30多年。本研究旨在建立威布尔模型，以求平均失效时间(MTTF)分布参数的RUL估计值。因此，包括PA01-AP01二次泵在内，RSG-GAS反应器将具有更高的安全性、更长的使用寿命和更高的可靠性，故障率更小。研究方法是在可靠性达到目标百分比的情况下，对收集的数据进行处理并估计威布尔模型的参数，根据MTTF值确定维修时间表或检查间隔。结果表明，得到了RSG-GAS反应器的RUL估计。在实施的研究中，对PA01-AP01次泵(型号为KSB，型号为CPK-S350-400)规定了维护时间表，可靠性为90%，RUL估计约为29天。
