An evaluation is presented of 53 instrumented burnout runs and one intentional physical burnout run. These data indicate that the addition of ribs to the outer (annular) channel of the Tubular Test Section resuits in a reduction of the average burnout heat transfer limits for the assembly. This is due to the fact that the ribs cause a flow reduction in the outer channel where the burnout probably originates. Comparison of the calculated burnout heat fluxes for only the ribbed and unribbed outer channels shows that any variation was well within experimental accuracy of the data. These tests also confirmed recent studies which indicated that for large internally heated annuli the reverse mass velocity effect extends a considerable distance into the subcooled region. In order to assure the same flow split as the HWCTR UO/sub 2/ fuel tube and hence establish its correct burnout limits, the Composite Tubular Test Section is being fabricated to simuiate inlet and exit configurations in addition to the heater tube dimensions. In this test section separate burnout indications will be obtained from both the inner and outer channels. (auth)
