Fuel Cladding Transient Tester (FCTT) data from experiments being performed at Hanford Engineering Development Laboratories have been evaluated to establish a basis for assessing the margin of safety provided by the fuel pin transient performance design criteria for Transient Overpower events (TOP). The FCTT data analyses indicate that: most failures occur below the cladding temperature limits for upset (1450/sup 0/F) and emergency (1600/sup 0/F) events, residual strength values less than those used in the CDF analysis (0.736 to 0.864 of unirradiated values) were observed (for fluences less than one-third of goal exposures), and failures with incremental strain values below the design limit (0.1 percent) were observed and the scatter in these strain data is large.
