Abstract
In the process of operation of RBMK reactors damage took place on welded pi pings produced from austenitic stainless steel of the type 08X18H10T. The i nspection of damaged sections in pipings has shown that in most cases crack -like defects were of corrosion and mechanical character. This paper consid ers in detail the reasons for the damage appearance and their development f or this type of welded joints of downcomers (empty set 325 x 16 mm, which w ere fabricated from austenitic stainless steel using TIG and MAW welding me thods.
