Deposits of Metallic Impurities in Cracks of Creep-Rupture Specimens of Type 304 ss Tested in Flowing Sodium
Numerous structural and containment components of Liquid Metal Fast Breeder Reactors will be exposed to a flowing sodium environment at elevated temperatures. Therefore a joint program between INTERATOM, the Nuclear Research Center, KFK, and the Studiecentrum voor Kernenergie, SCK/CEN, was conducted to determine quantitatively the influence of a flowing sodium environment upon the creep-rupture behavior of Type 304 ss at 550°C. The sodium tests were performed in the three non-isothermal dynamic loops of these companies and for a valid comparison parallel tests in air were carried out with the same heat.
