| 英文摘要 | An accelerator driven sub-critical (ADS) system consists of an accelerator, a sub-critical reactor, and a spallation target located at the centre of the reactor core. In this paper, we report the conceptual design of the control system for ADS system, which will integrate two big nuclear facilities, an accelerator and a reactor, into an overall system for the first time in the world. Because varied expectations on redundancy, diversity, availability, reliability, communication speed and latency are required for both accelerator and reactor, at least six systems have been designed for an ADS system, i.e. a main control system, three protection systems, a timing system, and a data archiving system. The main control system is designed to monitor and control the overall ADS system. In order to exactly couple the high-energy beam from the accelerator to the spallation target located in the reactor, many instrumentations are required in the main control system, such as instrumentations for beam monitoring and beam switching-off, instrumentations for ex-core neutron monitoring, instrumentations for in-core temperature and neutron monitoring, instrumentations for monitoring and controlling several cooling loops, and Instrumentations for control rod system. In order to enhance the safety of the ADS system during the operation, three protection systems, a reactor protection system, an accelerator's machine protection system and a personnel protection system, have been designed. Independent network is used for each system. Furthermore, both redundant network and hardwired communication are used in each protection system to provide extremely reliable communication link. Finally, the communication network with parallel redundancy protocol has been studied for the main control system. In comparison with a network without redundancy, the parallel redundancy protocol can improve dramatically the reliability of a communication network by up to forty thousand times. |
