Interim report on whole rod testing

Work has only been conducted on a limited inventory of irradiated rods made by Westinghouse for the Turkey Point Unit 3. The measured cladding strain was sufficiently large so that failure mechanism verification by inducing breaches in intact unmodified fuel rods at elevated temperatures in short periods of time does not appear to be practical. While stress-rupture has not been completely eliminated as a failure mechanism, for temperatures where the irradiation damage is annealed, Blackburn's recipe appears to give a very conservative estimate of breach times. The fuel apparently exhibited no additional gas release or axial fission product migration at 900/sup 0/F. The NDE gave no indication of deterioration of the fuel rod condition. 5 figures.
