The results of the solar insolation analysis are consistent with the results of a two-dimensional axisymmetric finite element analysis performed by Ohashi and Ortega(8727) [4]. The thermal conditions defining each of the scenarios and the maximum predicted flange temperature for each scenario are shown in Table 9. The table also reports the time at which the C9 thermal test is no longer able to adequately overestimate the flange temperature for each of the different scenarios, the cross over time. Since the cross over time for each of the scenarios is greater than the time the maximum flange temperature is reached (approximately 90 minutes), the C9 thermal test provides a conservatively high estimate of the maximum flange temperature in each scenario. This indicates that the pre-heating technique used in the various thermal tests is capable of taking into account the thermal effects present in a filled container. The results also show that as performed, the thermal tests provide a conservatively high estimate of the maximum flange temperature for several scenarios that meet or exceed the Federal regulations. 39
