Improved CANDU-core homogenization and benchmark models

CANDU反应堆要继续成为安大略省能源供应的重要贡献者，就必须满足日益增长的经济和安全需求。特别是，对于现有和未来的CANDU反应堆的安全分析，需要越来越准确和详细的模拟模型。这项工作的广泛目标有两个：通过使用先进的均匀化方法，开发一种新的、更准确的计算核反应堆中中子功率分布的方法，并开发详细的CANDU特定基准问题来测试新开发的方法，以及加拿大核工业目前使用的其他方法和代码。

For CANDU reactors to continue to be an important contributor to the Ontario energy supply they have to satisfy ever increasing economic and safety demands. In particular, increasingly accurate and detailed simulation models are required for the safety analysis of existing, as well as future, CANDU reactors. The broad objective of this work is twofold: To develop a new, more accurate, method for calculating the neutron power distribution in a nuclear reactor by using advanced homogenization methods and to develop detailed CANDU-specific benchmark problems to test the newly-developed method, as well as other methods and codes in current use in the Canadian nuclear industry.
