我国自行设计建造的高通量工程试验堆,经综合调试后于1980年12月16日达到第一炉额定满功率。综合调试是在完成安装试车之后进行的,它包括短路试车、综合试车和整修等项目。短路试车的目的是:清洗回路、进行主泵特性试验以及确定主泵的启动方式等。综合试车的目的是:验证冷却剂进堆流量、堆内部件振动,进行堆内部件操作试验、控制棒落棒试验、系统热态运行试验以及停电试验等,为堆首次物理临界创造条件。本堆的首次物理临界试验就在以上综合调试的基础上完成的。 在堆首次达到临界后,对调试中出现的问题作了处理,之后又恢复了临界,作了零功率及低功率试验,取得大量物理试验数据,在此基础上,进入逐步提升功率阶段,作了提升功率试验,最终达到第一炉额定满功率。本文着重介绍短路试车及综合试车的情况。
China’s own design and construction of high-throughput engineering test reactor, after comprehensive commissioning in December 16, 1980 to reach the first furnace rated full power. Integrated commissioning is done after the completion of the installation test run, which includes short circuit test, comprehensive test and renovation projects. The purpose of short circuit test is: cleaning circuit, the main pump characteristics of the test and determine the main pump start mode. The purpose of the integrated test is to validate the coolant flow into the reactor, the vibration of the internal components of the reactor, the operation test of the components inside the reactor, the test of falling of the control rod, the hot running test of the system, and the blackout test, which create the conditions for the first physical critical condition of the reactor. The reactor’s first physical critical test was completed on the basis of the above comprehensive commissioning. After the reactor reached the critical point for the first time, the problems that occurred during commissioning were dealt with. After that, the critical condition was resumed. Zero power and low power tests were conducted. A large number of physical test data were obtained. On this basis, the power stage was gradually upgraded To enhance the power test, and finally reach the first full rated power furnace full power. This article focuses on the short circuit test and integrated test run situation.
