Download or read book Visual Examinations of K West Fuel Elements written by and published by . This book was released on 1997 with total page 72 pages. Available in PDF, EPUB and Kindle. Book excerpt: Over 250 fuel assemblies stored in sealed canisters in the K West Basin were extracted and visually examined for damage. Substantial damage was expected based on high cesium levels previously measured in water samples taken from these canisters. About 11% of the inner elements and 45% of the outer elements were found to be failed in these examinations. Canisters that had cesium levels of I curie or more generally had multiple instances of major fuel damage.

Available in PDF, EPUB and Kindle. Book excerpt: A statistical evaluation of K West fuel visual examination results was performed in an attempt to correlate observed fuel damage levels with parameters known from storage records and parameters obtained from in-basin measurements.
Download or read book Visual Examinations of K East Fuel Elements written by and published by . This book was released on 1997 with total page 59 pages. Available in PDF, EPUB and Kindle. Book excerpt: Selected fuel elements stored in both ''good fuel'' and ''bad fuel'' canisters in K East Basin were extracted and visually examined full length for damage. Lower end damage in the ''bad fuel'' canisters was found to be more severe than expected based on top end appearances. Lower end damage for the ''good fuel'' canisters, however, was less than expected based on top end observations. Since about half of the fuel in K East Basin is contained in ''good fuel'' canisters based on top end assessments, the fraction of fuel projected to be intact with respect to IPS processing considerations remains at 50% based on these examination results.
Download or read book Test Plan for Techniques to Measure and Remove Coatings from K West Basin Fuel Elements written by and published by . This book was released on 1998 with total page 66 pages. Available in PDF, EPUB and Kindle. Book excerpt: Several types of coatings have previously been visually identified on the surface of 105-K East and 105-K West Basins fuel elements. One type of coating (found only in K West Basin) in particular was found to be a thick translucent material that was often seen to be dislodged from the elements as flakes when the elements were handled during visual examinations (Pitner 1997). Subsequently it was determined (for one element only in a hot cell) that this material, in the dry condition, could easily be removed from the element using a scraping tool. The coating was identified as Al(OH)3 through X-ray diffraction (XRD) analyses and to be approximately 60 [mu]m thick via scanning electron microscopy (SEM). However, brushing under water in the basin using numerous mechanical strokes failed to satisfactorily remove these coatings in their thickest form as judged by appearance. Such brushing was done with only one type of metal brush, a brush design previously found satisfactory for removing UO4.xH2O coatings from the elements.

Book excerpt: Nine outer fuel elements were recovered from the K East Basin and transferred to a hot cell for examination. Extensive testing planned for these elements will support the process design for the Integrated Process Strategy (IPS), with emphasis on drying and conditioning behavior. Visual examinations of the fuel elements confirmed that they are appropriate to meet testing objectives to provide design guidance for IPS processing parameters.

This book was released on 1997 with total page 49 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Characterization of Spent Nuclear Fuel in the sealed K West canisters involves four steps, (1) sampling of gas/liquid, (2) ''Lift-and-Look'' visual examinations of fuel elements, (3) sampling of canister sludge, and (4) retrieving fuel for hot cell examinations. This document indicates the choices of particular canisters that were examined during the second characterization campaign in the Hanford K West Basin.

Download or read book Drying Damaged K West Fuel Elements Summary of Whole Element Furnace Runs 1 Through 8 written by and published by . This book was released on 1998 with total page 45 pages. Available in PDF, EPUB and Kindle. Book excerpt: N Reactor fuel elements stored in the Hanford K Basins were subjected to high temperatures and vacuum conditions to remove water. Results of the first series of whole element furnace tests i.e., Runs 1 through 8 were collected in this summary report. The report focuses on the six tests with breached fuel from the K West Basin which ranged from a simple fracture at the approximate mid-point to severe damage with cladding breaches at the top and bottom ends with axial breaches and fuel loss. Results of the tests are summarized and compared for moisture released during cold vacuum drying, moisture remaining after drying, effects of drying on the fuel element condition, and hydrogen and fission product release.

Download or read book Optical Sensors for Structural Health Monitoring written by Paulo Antunes and published by MDPI. This book was released on 2021-03-12 with total page 248 pages. Available in PDF, EPUB and Kindle. Book excerpt: The evolution and need for the preservation and maintenance of existing structures, recent or historical, has fostered research in the area of structural monitoring, translated into the development of new techniques, equipment and sensors. Early detection of damage and accurate assessment of structural safety requires monitoring systems, the data from which can be used to calibrate numerical models for structural analysis and to assess safety. Data are obtained under real-time conditions, considering a group of parameters related to structural properties, such as stresses, accelerations, deformations and displacements. The analysis of structural properties is particularly relevant when the structure is subjected to extreme events (earthquakes, wind, fire and explosions, among others) or repeated loads (road/rail/air traffic, vibrations induced by equipment and machines), since they affect the structural integrity and put the users at risk. In order to prevent the severe damage and eventual collapse of structures, and consequent human, material and economic losses, the implementation of monitoring systems becomes a valuable tool for today's society. Monitoring of structures is becoming increasingly important, not only as preventive action, but also due to actual economic and sustainability concerns, to ensure a safer and more comfortable built environment.
