采用去耦合法,在未作任何假定的条件下,导出了点堆中子动力方程组的精确解。此解可通用于反应堆启动,次临界、缓发超临界,一直到瞬发超临界。此解计算精度高,可用于要求计算精度较高的定量分析,计算工作量小,可用手算。对于反应堆现场运行监督性快速估计的计算,尤为适宜。 相似文献

Russian naval nuclear fuel and reactors pose both proliferation and environmental threats, ranging from the possible theft of highly enriched uranium fuel to the radioactive contamination of the environment, whether due to accident, neglect, or sabotage. Current conditions at Russian naval bases, together with a history of accidents and incidents involving Russia's nuclear fleet, make a convincing case for the large-scale assistance that the G8 is now providing to improve the safety and security of Russian naval reactors and fuel. However, virtually no data has been released to allow accurate, reliable, and independent analysis of reactor and fuel properties, risking misguided international efforts to assist in the areas of nuclear cleanup, nonproliferation, and security. This article identifies and assesses relevant properties and developments related to reactor and fuel design, provides a comprehensive presentation of Russian nuclear naval technologies, and examines technological trends in the context of proliferation and environmental security. 相似文献
