42KhNM Alloy and Silicon Carbide as Material for Accident-Tolerant Fuel-Rod Cladding

The results of R&D work on alternative materials for accident-tolerant fuel-rod cladding are reported. The chromium-nickel alloy 42KhNM and multilayer composite material SiC/SiC are considered. The advantages in terms of corrosion resistance of alternative materials over the conventional zirconi...

Description
Summary:The results of R&D work on alternative materials for accident-tolerant fuel-rod cladding are reported. The chromium-nickel alloy 42KhNM and multilayer composite material SiC/SiC are considered. The advantages in terms of corrosion resistance of alternative materials over the conventional zirconium alloys are shown. The results of efforts to optimize a method for welding pipes made of alloy 42KhNM and sealing fuel-rod cladding made of composite materials are presented. A complex of pre-reactor and reactor studies is required to evaluate the possibility of using the materials under consideration as fuel-rod cladding.
