Behaviour of Radioactive Isotopes in Liquid Metal Cooled Fast Reactors. Pt.5. The Behaviour of exp 134 Cs, exp 137 Cs and exp 22 Na in a Small Stainless Steel Pumped Loop

摘要

A small scale, all AISI 316 stainless steel, pumped loop has been operated with exp 134 Cs, exp 137 Cs and exp 22 Na in the sodium. The loop has a distillation sampler, oxygen meter, two cold traps and a small subsidiary pumped loop initially containing the isotopes adsorbed on uranium oxide. The distribution of the isotopes within the loop has been determined over the temperature range 100 to 300 exp 0 C with 1 to 2 ppm of oxygen in the sodium and a sodium velocity about half the Reynolds number required for the onset of turbulence in the vertical legs.
