Modeling and Diagnostic Techniques Applicable to the Analysis of Pressure Noise in Pressurized Water Reactors and Pressure-Sensing Systems

摘要

Pressure noise data from a PWR are interpreted by means of a computer-implemented model. The model's parameters, namely hydraulic impedances and noise sources, are either calculated or deduced from fits to data. Its accuracy is encouraging and raises the possibility of diagnostic assistance for nuclear plant monitoring. A number of specific applications of pressure noise in the primary system of a PWR and in a pressure sensing system are suggested. (ERA citation 10:004627)
