Abstract
Identification and elemental analysis of products of chemical degradation resulting from an operational accident in the drying unit of the Vivitron has been carried out with the aid of neutron activation. The examination of solid and liquid samples taken from various parts of the circuit revealed the presence of extremely corrosive mixtures of hydrofluoric, sulfurous and sulfuric acids, which lead to the attack of metallic and synthetic surfaces and the formation of metal salt derivatives. A major accident in the gas transfer system of the Vivitron occurred in the gas-drying towers following a reactivation process of the alumina charge. This resulted in severe damage to various parts of the system and serious pollution of the entire Vivitron from degradation products of SF{sub 6}. In consequence, all tests were ceased and extensive repairs and cleaning of the Vivitron were undertaken. This work is in progress and will expectedly be terminated by end of January 1992.
