[en] The Reactor TRIGA PUSPATI (RTP) at Malaysia Nuclear Agency is a TRIGA Mark II type reactor and pool type cooled by natural circulation of light water. This paper describes on big data analytic for reactor performance of operational, safety and non-safety RTP parameters based on log power, linear power, period, Fuel and coolant temperature, seismic activity and reactivity parameter with using safety and non-safety instrumentation system and wide-range neutron measurement system(WR-NMS). Methodology of Big data analytic is to evaluate and analysis of continuous component monitoring which provides early detection of failure in reactor safety and control. Reactor Operational, safety and non-safety system will use to estimate power measurement, radiation dose, reactor period, seismic activity and others during reactor operation and non-operation. This study also focuses on noise fluctuation from fission chamber during reactor operation. This work will present result of big data analytic from RTP which indicated the safety parameter identification and initiate safety action on crossing the threshold set point trip. Concluded that optimization Reactor operational, safety and non-safety will have improved the reactor control and safety parameter of reactor during operation and non-operation. (author)
