    • 摘要: 加速器驱动次临界系统(Accelerator Driven subcritical System,ADS)可用于发电、增殖和嬗变等多种用途.在瞬态变工况时,需要实现功率的准确调节,以保证反应堆瞬态的安全性.我国自主设计的加速器驱动嬗变研究装置CIADS(China Initiative Accelerator Driven System)次临界反应堆仅依靠加速器外中子源强度实现对堆芯功率调节.为研究基于外中子源强度的CIADS堆芯控制响应特性,采用集总参数法建立堆芯非线性模型,利用微小扰动线性化方法对堆芯非线性模型进行线性化处理,建立双输入双输出的堆芯状态空间模型.基于该模型设计堆芯功率模糊PID(Proportional Integral Derivative)控制器,开展扰动控制仿真.研究表明:在不同外中子源相对强度扰动或堆芯进口温度扰动下,采用模糊PID控制器可实现对堆芯相对功率的良好控制.%[Background] Accelerator driven subcritical system (ADS) can be used for power generation, proliferation and transmutation. China initiative accelerator driven system (CIADS) is a self-designed ADS research facility in China. It only relies on the intensity of neutron source outside the accelerator to regulate the core power. [Purpose] This study aims to accurately regulate power in transient conditions to ensure the transient safety of the reactor based on the strength of external neutron source. [Methods] The lumped parameter method was used to establish the core nonlinear model of CIADS, and the micro-disturbance linearization method was used to linearize the core nonlinear model. Dual-input and dual-output core state space model was established, and core power fuzzy proportional integral derivative (PID) controller was designed to carry out disturbance control simulation to obtain the core control response characteristics of CIADS. [Results&Conclusion] The simulation results show that the use of fuzzy PID controller can achieve good control of core relative power under the different external neutron source relative intensity disturbance or core inlet temperature disturbance.

    • 摘要: 针对加速器驱动次临界系统(Accelerator Driven Sub-critical System, ADS)注入器Ⅰ束流调试要求,需要精确测量束流的相位和能量.本文研究束流的相位和能量高精度测量方法,设计了基于快速电流变压器(Fast Current Transformer, FCT)信号的相位及能量测量系统.该系统包括FCT探头、前端电子学、数据采集和处理三个部分,通过正交采样的方式实现束流的相位测量,然后利用飞行时间法实现束流能量的测量.测试结果表明,该系统在实验室测试相位分辨率为±0.8°,在线测试相位分辨率为±2°,满足直线加速器的设计要求.%[Background] Injector Ⅰ is a key component of accelerator driven sub-critical system (ADS), phase and energy of the beam need to be known by the operator. [Purpose] This study aims to precisely get and control the beam phase and energy of ADS and develop a beam energy measurement system based on fast current transformer (FCT) signal. [Methods] FCT detector, signal processing electronics and data acquisition system are designed and integrated to implement the measurement system. The beam energy is measured in terms of beam phase which is obtained by the in-phase and quadrature-phase sampling. The precise phase measurement of the high-frequency signal is realized by the down-conversion technique. [Results] Phase resolutions obtained in the laboratory and on-line operation were ±0.8° and ±2°, respectively. [Conclusion] The system proposed in this study meets the design requirements of the linear accelerator.

    • 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150 MeV/200 MeV)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.%[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.

    • 摘要: In accelerator-driven subcritical system (ADS),the transient characteristic is quite different from that of traditional critical system due to its strong external neutron source and its fuel composition for transmutation.This paper presents a coupled stochastic-deterministic method for analysing the transient characteristic of ADS.After comparing various reactor transient calculation methods,predictor-corrector improved quasi-static method was chosen to handle the time variable of neutron spacetime kinetics equation.Considering the specific neutron spectrum,Monte Carlo method was used to handle the corresponding spatial,angle and energy variables.The main problem encountered is the Monte Carlo iteration instability for slightly subcritical system.Numerical results demonstrates the effectiveness of the new method.%针对加速器驱动次临界系统(ADS)瞬态问题,采用预估校正改进准静态方法(PCQS)处理时空中子动力学方程中的时间自变量,采用蒙特卡罗方法处理相应的空间-角度-能量自变量,重点解决了低次临界度下模拟计算不稳定的问题,验证了TWGIL-Seed-Blanket动力学基准问题和小型模拟ADS问题,得到瞬态过程的功率变化结果,与基于其他方法的程序比较,经初步验证取得了较好结果,证明了该耦合方法可行.

    • 摘要: Beam distribution with the regular and homogeneous form on spallation target or beam dump is an imperious demand for spallation neutron source (SNS),accelerator driven sub-critical system (ADS),and so on.Nowadays,adopting nonlinear antisymmetric high order field is very infusive for distribution transformation of beam.Here,a simplified dodecapole field magnet (SDFM),well focusing particles in beam halo to inner layer of beam halo or beam core,was introduced.Combining SDFM with antisymmetric sextupole,octupole or decapole magnet can theoretically get approximate uniformly distributed round beam with slightly larger size.The conceptual design,physics structural and its manufacturing method of SDFM was presented.%在散裂靶或废束站上形成均匀的、形状规则化的束斑分布,是散裂中子源、加速器驱动次临界系统(ADS)等高功率强流质子束应用研究课题中共性的关键技术.目前国际上一般认为采用反对称非线性高阶场磁铁进行打靶束斑均匀化变换是较为合适的.提出了一种新颖的非线性场磁铁——反对称垂直双向聚焦简易十二极场磁铁,该磁铁可以在交叉垂直的两个方向同时聚焦束晕粒子至束核内层或束团中心区域,可以较好地控制束晕;并配合其他反对称高阶场磁铁或阶梯场磁铁,可以在靶上较容易地得到基本均匀分布的近似圆斑束.同时给出了该种磁铁的结构装置及其制造方法.
