Abstrakt

In reactor safety studies there are many situations in which the extreme assumption made in assessing fuel can or fuel container temperatures is that heat is transferred by radiation only. The emittance of the surface in question is therefore of importance.
This paper describes measurements of the normal emittance of Stainless Steel at temperatures up to 600°C. Tests were completed in both air and argon atmospheres and a wide range of prepared surfaces was investigated.
The work has highlighted the difficulty of defining the emittance of this material. The material history, test atmosphere, test time, surface treatment - in fact not surprisingly any condition that influences the fine structure of the surface can cause significant increases of the emittance.
