燃料组件程序ROBIN-1.7的验证和确认

Verification and Validation of Lattice Code ROBIN-1.7

利用国际公开基准题开展ROBIN-1.7燃料组件计算程序的共振计算、输运计算、燃耗计算等模块的验证工作。分别利用临界基准问题、蒙特卡罗程序、OECD NEA燃耗基准问题及其他输运-燃耗基准问题等对ROBIN-1.7程序进行确认。验证及确认结果表明,ROBIN-1.7程序的共振计算、输运计算、燃耗计算等模块及集成计算结果是正确的;ROBIN-1.7程序对各问题主要物理参数(如反应性、棒功率分布以及同位素浓度)的计算精度达到了国际同类商业程序的水平,满足在压水堆中工程应用的要求。

Verification and validation of lattice code ROBIN-1.7 is performed by using international public benchmark problems, which include critical experiments data, depletion benchmark problems of OECD NEA and other neutron transport-depletion calculations with MCNP code. The result(reactivity, pin power distribution, isotope concentration) shows that independent modules of ROBIN-1.7 such as resonance treatment module, neutron transport module and depletion module are developed and integrated correctly. It is also demonstrated that ROBIN-1.7 has reached the industry level for PWR application.
