(R&amp;A) of generator rotors is performed using the B-SURE\u00ae (Boreside Surface and Ultrasonic Rotor Examination) system. The examination process is similar to the one used for steam turbine rotors except that in most cases a oil-tight boot needs to be installed in the main bore after the turbine end plug is removed.<\/p><p align=\"JUSTIFY\">The boot is installed to prevent any honing oil or turbine oil used during boresonics from contaminating the end windings under the exciter end retaining ring. The only time the boot is not installed is when the Copper bar is completely removed and the bore is accessible from both ends (turbine and exciter end).\u00a0<span style=\"letter-spacing: var(--bodyletterspacing); text-transform: var(--bodytexttransform);\">In some generator rotors there may be a set of flux bars that need to be removed immediately after plug removal and prior to boot installation.\u00a0<\/span><\/p><p align=\"JUSTIFY\"><span style=\"letter-spacing: var(--bodyletterspacing); text-transform: var(--bodytexttransform);\">Power honing and boreside NDE are performed and if no significant indications are detected, the boot is removed, the flux bars reinstalled (if flux bars are present), and a new replacement plug is installed. The results of the boresonics are used in conjunction with the rotor material properties, operating stress calculations, and fracture mechanics analysis to perform a life assessment of the rotor to determine current condition and suitability for future service. The life assessment yields a reinspection interval if no significant indications are detected or a recommendation is provided to change the rotor future operating conditions, rotor repair, or rotor replacement in case that significant indications are detected.<\/span><\/p>\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<section class=\"elementor-section elementor-inner-section elementor-element elementor-element-45dca1d elementor-section-boxed elementor-section-height-default elementor-section-height-default\" data-id=\"45dca1d\" data-element_type=\"section\">\n\t\t\t\t\t\t<div class=\"elementor-container elementor-column-gap-default\">\n\t\t\t\t\t<div class=\"elementor-column elementor-col-50 elementor-inner-column elementor-element elementor-element-3c7f9bf\" data-id=\"3c7f9bf\" data-element_type=\"column\">\n\t\t\t<div class=\"elementor-widget-wrap elementor-element-populated\">\n\t\t\t\t\t\t\t\t<div class=\"elementor-element elementor-element-4d63880 elementor-widget elementor-widget-image\" data-id=\"4d63880\" data-element_type=\"widget\" data-widget_type=\"image.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t<style>\/*!

(ID) of the retaining rings using refracted shear waves to provide ultrasonic images of the ID surface of the rings. The system is calibrated to be sensitive to the detection of a defect having dimensions of less than 0.015&#8243; deep x 0.2&#8243; long at a signal-to-noise ratio of 2 to 1. The ultimate examination sensitivity is dictated by the acoustic characteristics of the material volume.\u00a0<\/p><p align=\"JUSTIFY\">A manual scan is performed prior to the automated scanning to render the ring ID profile and attenuation measurements. Form reflector discrimination examinations is performed utilizing specially designed ultrasonic search units used to differentiate ID reflectors in the &#8220;shrink-fit&#8221; areas from that of superfluous signals occurring below the ring bore. The scanning is done in 4 sectors around the ring and two sections designated as taper or shrink-fit area and ring body. The generator rotor is not required to be rotated since the scanner rotates around the ring circumference.<\/p>\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-71aed9f elementor-widget elementor-widget-image\" data-id=\"71aed9f\" data-element_type=\"widget\" data-widget_type=\"image.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<img loading=\"lazy\" decoding=\"async\" width=\"593\" height=\"372\" src=\"http:\/\/reinhartassoc.com.previewc38.carrierzone.com\/wp-content\/uploads\/2023\/09\/AUT-1.png\" class=\"attachment-medium_large size-medium_large wp-image-160\" alt=\"\" srcset=\"http:\/\/reinhartassoc.com.previewc38.carrierzone.com\/wp-content\/uploads\/2023\/09\/AUT-1.png 593w, http:\/\/reinhartassoc.com.previewc38.carrierzone.com\/wp-content\/uploads\/2023\/09\/AUT-1-300x188.png 300w\" sizes=\"auto, (max-width: 593px) 100vw, 593px\" \/>\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t<section class=\"elementor-section elementor-top-section elementor-element elementor-element-e2a970e elementor-section-boxed elementor-section-height-default elementor-section-height-default\" data-id=\"e2a970e\" data-element_type=\"section\">\n\t\t\t\t\t\t<div class=\"elementor-container elementor-column-gap-default\">\n\t\t\t\t\t<div class=\"elementor-column elementor-col-100 elementor-top-column elementor-element elementor-element-171ab3b\" data-id=\"171ab3b\" data-element_type=\"column\">\n\t\t\t<div class=\"elementor-widget-wrap elementor-element-populated\">\n\t\t\t\t\t\t\t\t<div class=\"elementor-element elementor-element-0bbf7db elementor-widget elementor-widget-spacer\" data-id=\"0bbf7db\" data-element_type=\"widget\" data-widget_type=\"spacer.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t<div class=\"elementor-spacer\">\n\t\t\t<div class=\"elementor-spacer-inner\"><\/div>\n\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-85161cc elementor-widget elementor-widget-heading\" data-id=\"85161cc\" data-element_type=\"widget\" data-widget_type=\"heading.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t<h2 class=\"elementor-heading-title elementor-size-default\">Generator dovetail slot and wedging testing<\/h2>\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-63e8359 elementor-widget elementor-widget-text-editor\" data-id=\"63e8359\" data-element_type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t<p align=\"JUSTIFY\">Some generator rotors are required to have their slot dovetails examined due to potential cracking starting on the periphery at the dovetail slots.
