Abstract

Abstract: In this work, Cobalt-free alloys are prepared as a capsule in which radioactive waste is placed for disposal, and this is a preventive measure to rid the environment of radioactive waste and bury it deep in the earth in a capsule. So, the buildup factor was measured for 1-5-10-40 MFP. The mechanical properties (hardness and toughness) of the processed samples were studied. The hardness was calculated by the Vickers hardness test additionally; the tolerance process was carried out using concentrated chloride acid for 30 days and NaCl 3.5% for 30 days for the studied samples. In this work the resulted developed alloys are resistant to stainless steel 316 L and therefore the alloys are a suitable material in the nuclear field as a container for burying and disposing of waste. Highlights: A developed steel alloys cobalt free were developed radioactive waste capsule. Hardness testing and corrosion resistance were measured. Buildup factor was calculated using Geant4. The developed samples has importance in the nuclear applications.
