Abstract:
Analysis of neutronic and thermal-hydraulics fluctuations has various applications in calculation or measurement of the core dynamical parameters (temperature reactivity coefficients) furthermore it is applicable in thermal-hydraulics surveillance and diagnostics. Experience of the Fukushima Dai-ichi plant and the lessons learned from the European stress tests, demonstrated that alternative and various tools and methods are needed for the reactor's condition identification. In this paper the feasibility of development of an alternative accident monitoring via eminent coupling of neutron and thermal-hydraulics noise is proposed. and it is programming a simple simulator for calculating kinetics and thermal-hydraulics noise approximately during accident for demonstration of possibility of accident predictions in the beginning of event. The potency of proposed method is shown by modeling four accidents utilizing aforementioned simulator and it is investigated possibility of accident predictions
