Test plan for Series 2 thermogravimetric analyses of spent fuel oxidation

Technical Report ·
OSTI ID:59787
Preliminary studies indicated the need for more spent fuel oxidation data in order to determine the behavior of spent fuel as a waste form for a tuff repository. Short-term thermogravimetric analysis (TGA) tests were recommended in a comprhensive technical approach as the method for providing scoping data that could be used to: (1) evaluate the effects of variables such as moisture and burnup on the oxidation rate; (2) determine operative mechanisms; and (3) guide long-term, low-temperature oxidation testing. This document reviews the preliminary TGA results and presents the Series 2 test plan to study the effect of moisture and temperature on oxidation rate and phase formation.
