Analysis of the effect of pollution of component surfaces as a result of possible contact of fresh nuclear fuel with sea atmosphere on corrosion

Abstract

Acquisition and analysis of the information was performed on possible effect of components of sea atmosphere in case of their precipitation on the assembly surfaces on the corrosion of structural materials of items of fuel assemblies (FAs) of water-water energetic reactor (VVER-1000) in their subsequent operation. The data is presented on static and dynamic tests of alloy E-110 at temperatures of 300–350 С in water and standard coolant of the reactor polluted with chlorides and iodine, as well as of alloy E-110 under special pollution of its surface with chlorides. It is demonstrated that in keeping the conditions of storage of fresh fuel, as well as the recommendations of the present work, its high corrosion resistance and operability in further operation is ensured.

Review of the Latest Opinions and Theories Regarding the Development of Technical and Agricultural Sciences

“…Among the ocean salts, the major ones are sodium and magnesium chlorides and sulphates. Among the chlorides, the basic dissolved compounds are: NaCl (27 g/L), MgCl 2 (6 g/L), KCl and CaCl 2 (1 g/L each) [283][284][285][286][287]. Namely such compounds and in such ratio are recommended to be taken for preparation of solution in climatic tests of the equipment under the conditions of sea (salt) fog [288][289][290].…”
