摘要

在加速器驱动次临界系统（Accelerator Driven Sub-critical Systems，ADS）中，散裂源中子能量可以到达上百MeV甚至GeV，能谱分布非常复杂，已有的工作核数据库的截面数据无法满足其设计要求。传统工作核数据库的制作方法人工操作干预过多、耗时、繁琐且易出错，为此，开发出自动生成数据库程序。该程序在设计的能群结构、权重函数等参数基础上，通过程序自动生成适用于ADS系统的点状ACE格式和471群MATXS格式核数据库ANDL-ADS（Auto-generated Nuclear Date Library for ADS），支持高能中子（能量上限为150MeV/200MeV）的截面制作，并可根据需求进行多温截面的制作。通过不同材料的临界球、积分泄露率、高能屏蔽等基准例题的测试，初步验证了ANDL-ADS数据库的可靠性。

Abstract

Background

In the accelerator driven sub-critical systems (ADS)

the energy of spallation neutron source can reach hundreds of MeV or even GeV

and the distribution of energy spectrum is very complex. The existing working nuclear date libraries cannot meet its calculation requirements. The traditional methods of creating nuclear library are too much artificial intervention

time-consuming

cumbersome and error-prone.

Purpose

The study aims to develop a nuclear data library that satisfies the requirements of ADS systems design and analysis.

Methods

A multi-temperature library automatic generation program was developed to auto-generate a neutron nuclear date library ANDL-ADS (Auto-generated Nuclear Date Library for ADS) in both the point-wise date ACE format and the 471-group MATXS format according to the preset parameters.

Results

The reliability of ANDL-ADS is preliminarily verified by testing benchmark examples of criticality

leakage integral and high energy shielding.

Conclusion

Preliminary tests have been carried out on ANDL-ADS. Further benchmark tests and comprehensive applications are required to verify the reliability of cross sectional data fully.
