Abstract : The interaction of steel with a molten sodium flow has been studied in experimental loops with forced coolant circulation. During a first stage of the work, the behaviour in sodium of the basic components of steel - iron, nickel and chromium - was studied. The tests showed that nickel reacts particularly sharply to any change in (experimental) conditions: its stability is markedly affected by increases in temperature and sodium velocity. The manner in which variations of the iron, nickel and chromium balance can affect the stability of different steels and alloys is considered. It is shown that changes in the chromium content (from 12 to 20 wt. percent) have little effect on the stability of steels (with constant nickel content of 15 wt. percent), but that the stability depends basically on the ratio of iron to nickel: high nickel steels behave in sodium much as unalloyed iron. The effect on steel stability of alloying with certain other elements (e.g. C. N. Mn, Si, Nb, Ti, Mo, W) has also been studied. (Author)
