Groups of materials are compared according to their possible use for fuel-pin cladding in the development of accident-tolerant fuel (ATF). Ferritic, ferritic-martensitic, and austenitic steels and chromium-nickel alloys are studied. Currently, only the chromium-nickel alloy 42KhNM can be used in VVER under normal operating conditions as cladding material for ATF. Pre-reactor and reactor studies are required in order to assess the possibility of using for this purpose the other materials which are under consideration.

耐事故燃料背景下VVER燃料销的钢包层：前景

根据在耐事故燃料（ATF）的开发中燃料销钉覆层的可能用途，对材料进行了比较。研究了铁素体，铁素体-马氏体和奥氏体钢以及铬镍合金。目前，在正常工作条件下，VVER中只能使用铬镍合金42KhNM作为ATF的包覆材料。为了评估将其他正在考虑的材料用于此目的的可能性，需要进行反应堆前和反应器研究。
