| 英文摘要 | A fundamental analysis of helium-gas coolant leakage rate through first-wall cracks in Tokamak fusion reactors was made. Criteria for ascertaining the correct flow models were thoroughly investigated. After testing the criteria,it was determined that the correct model is the compressible choked flow for the helium-gas coolant after the normal operating conditions in the Tokamak fusion reactors. The upper bound leakage rates through metallic wall for two crack sizes were calculated. The calculated maximum numbers of allowable cracks through metallic and silicon-carbon composite wall were also reported. The experimental data of specimen S-23 (the small crack size), checked with the predicted or calculated leakage rate. But the experimental data of specimen S-4 (the large crack size, which is only 4.4 times larger than the crack size of specimen S-23) were two orders of magnitude higher than the calculated value. This is probably due to the many through-cracks undetected and therefore, not reported in the experiment, and not due to the difference in crack sizes.It should be noted that since there are only two test data points,it is recommended that more testing or experimental data will be needed. The results of two previous invetigations about the calculated leakage values,their equations used, and their flow models employed were also reviewed.It is concluded that the correct model for the analysis is the compressible choked flow, and that helium can be as an effective coolant for fusion power reactors. Several recommendations are also made．Specifically,more experiments for helium, and similar analysis and experiments for lithiu and water coolant are needed; and should be encouraged. |
