A method of non-destructively assessing a current condition of a number of tubes of a steam generator of a nuclear power plant, the method comprising: establishing a set of baseline parameters for each of a plurality of exemplary regions of interest (ROIs) of a number of the tubes of the steam generator; extracting with the use of an eddy current sensor a signal from each of a number of physical ROIs of a number of the tubes; comparing the signal from a given physical ROI of a tube with the set of baseline parameters of the corresponding exemplary ROI; and triggering additional processing when at least a portion of the signal from the given physical ROI exceeds at least a portion of the set of baseline parameters of the corresponding exemplary ROI; storing an exception data set for each of one or more physical ROIs of each of one or more tubes of the number of tubes, each exception data set being representative of a historic signal of the physical ROI that exceeds the set of baseline parameters of the corresponding exemplary ROI; wherein the triggering of additional processing comprises: identifying an exception data set for the given physical ROI; comparing the exception data set for the given physical ROI with the signal from the given physical ROI; and performing at least one of: triggering the need for still further processing if at least a portion of the signal from the given physical ROI exceeds at least a portion of the exception data set for the given physical ROI, refraining from the triggering of still further processing with respect to the given physical ROI when no portion of the signal from the given physical ROI exceeds by a predetermined threshold the exception data set for the given physical ROI. establishing a set of baseline parameters for each of a plurality of exemplary regions of interest (ROIs) of a number of the tubes of the steam generator; extracting with the use of an eddy current sensor a signal from each of a number of physical ROIs of a number of the tubes; comparing the signal from a given physical ROI of a tube with the set of baseline parameters of the corresponding exemplary ROI; and triggering additional processing when at least a portion of the signal from the given physical ROI exceeds at least a portion of the set of baseline parameters of the corresponding exemplary ROI; storing an exception data set for each of one or more physical ROIs of each of one or more tubes of the number of tubes, each exception data set being representative of a historic signal of the physical ROI that exceeds the set of baseline parameters of the corresponding exemplary ROI; wherein the triggering of additional processing comprises: identifying an exception data set for the given physical ROI; comparing the exception data set for the given physical ROI with the signal from the given physical ROI; and performing at least one of: triggering the need for still further processing if at least a portion of the signal from the given physical ROI exceeds at least a portion of the exception data set for the given physical ROI, refraining from the triggering of still further processing with respect to the given physical ROI when no portion of the signal from the given physical ROI exceeds by a predetermined threshold the exception data set for the given physical ROI. identifying an exception data set for the given physical ROI; comparing the exception data set for the given physical ROI with the signal from the given physical ROI; and performing at least one of: triggering the need for still further processing if at least a portion of the signal from the given physical ROI exceeds at least a portion of the exception data set for the given physical ROI, refraining from the triggering of still further processing with respect to the given physical ROI when no portion of the signal from the given physical ROI exceeds by a predetermined threshold the exception data set for the given physical ROI. triggering the need for still further processing if at least a portion of the signal from the given physical ROI exceeds at least a portion of the exception data set for the given physical ROI, refraining from the triggering of still further processing with respect to the given physical ROI when no portion of the signal from the given physical ROI exceeds by a predetermined threshold the exception data set for the given physical ROI.
