HYDRA and COBRA-SFS temperature calculations for CASTOR-IC, REA-2023, CASTOR-V/21, and TN-24P
The COBRA-SFS and HYDRA thermal analysis computer codes were used to perform ''pretest'' or ''prelook'' calculations on the CASTOR-1C, REA-2023, CASTOR-V/21 and TN-24P spent fuel storage casks. HYDRA results were compared to 24 different test runs, while COBRA-SFS results were compared to 25 runs. These comparisons included tests with three different fill media, vacuum (low-pressure nitrogen), helium, and nitrogen, in both horizontal and vertical casks. The mean difference in peak clad temperature for of all comparisons was +10/sup 0/C for HYDRA and +3/sup 0/C for COBRA-SFS. Their respective standard deviations were +-10/sup 0/C and +-11/sup 0/C. These comparisons have demonstrated that even with the limited amount of experience in modeling the thermal characteristics of casks, both codes do an excellent job of predicting peak clad temperatures for a wide variety of cask configurations.
