ARGON AS A PROTECTIVE ATMOSPHERE FOR MOLTEN SALTS

In reactors employing circulating molten salt fuels and having most of the Kr and Xe gases stripped from the fuel into the off-gas, argon may reasonably be used as the blanket (and stripping) gas. In such cases, the activity of Kr and Xe and their descendents so far exceeds that of Ar/sup 41/ and K/sup 41/ produced that no additional provision is needed for shielding. The amounts of Rb, Sr, Cs, and Ba are so much greater than that of K that no additional provision against chemical attack is needed. (auth
