Chemical compatibility of Eurofer steel with sodium-potassium NaK-78 eutectic alloy

Abou Sena, A.; Arbeiter, F.; Baumgartner, S.; Böttcher, T.; Heinzel, A.; Piecha, H.; Zinn, K.

Abstract:
In the high flux area of the IFMIF (International Fusion Materials Irradiation Facility) neutron source, the capsules of the High Flux Test Module (HFTM) contain SSTT Eurofer specimens for fusion-relevant irradiation at temperatures 250–550°C. Using the liquid metal NaK-78 eutectic alloy to fill the gaps among the Eurofer specimens stacked inside the HFTM capsules was introduced in order to improve the thermal conduction among all specimens and have uniform and predictable temperature distribution. Therefore the objective of this study is to investigate the chemical compatibility between Eurofer steel and NaK-78 to evaluate the applicability of this concept. ... mehr
