Download or read book Investigation of Fretting Wear of Cladding Materials in Liquid Lead written by Mattia Del Giacco and published by KIT Scientific Publishing. This book was released on 2014-07-31 with total page 270 pages. Available in PDF, EPUB and Kindle. Book excerpt: One promising concept for future nuclear reactors uses liquid metals like Pb as reactor coolant. In this work, fretting of fuel clad materials is investigated in Pb environment at relevant operating conditions. A novel test apparatus is presented that allows fretting tests in liquid lead with high accuracy and reproducibility also during long term tests. Tolerable operating conditions concerning fretting wear by evaluating the specific wear coefficient and the concept of fretting maps are given.
