Design and Analysis of Corrosion Experiments for Testing Materials Exposed to Gamma Radiation
The scope of metallurgical engineering applied research and development of cladding and encapsulation materials has been extended during recent years beyond those materials used in core and cladding and in non-core structural nuclear applications in research and power reactors. Materials for the encapsulation of radioisotopes for medical and commercial uses must also be carefully selected for their suitability for exposure initially up to two years in the reactor followed by four or five years in service. The susceptibility to corrosion of all of these materials is a most important consideration. Conventional weight loss and potentiostatic experiments require careful design of both the physical corrosion assembly and experimental method. In this paper a controlled laboratory experiment using a 50,000-Ci gamma irradiator is used as an example to exemplify the use of Statistical Design of Corrosion Experiments.
