Description

technical field [0001] The invention relates to the technical field of high-temperature gas-cooled reactor startup and shutdown systems, in particular to a test device and method for the control logic of the high-temperature gas-cooled reactor startup and shutdown system. Background technique [0002] The start-stop reactor system is an important part of the pebble bed modular high-temperature gas-cooled reactor nuclear power plant. During the start-up and stop of the unit, the system is mainly used to adjust the steam parameters at the outlet of the nuclear island steam generator to meet the start-up requirements of the steam turbine. The steam generator exports steam to the condenser to take away the heat generated by the reactor and ensure the cooling requirements of the steam generator and the reactor. [0003] The high temperature gas-cooled reactor start-stop reactor system includes a steam-water separation system and a working fluid state parameter control system comp...

Problems solved by technology

There are at least the following problems in this test method: when the operating conditions of the start-stop reactor system are complex and there are many measurements, the above manual test method has the disadvantages of reading errors and many errors in the test results, and the test efficiency is low; at the same time , the DCS logic needs to be modified during the test to simulate various operating states of the system. Since the start-stop reactor system involves the whole process of operating conditions during the unit start, stop and power operation stages, the DCS logic involved is relatively wide, and the test process directly Modifying the DCS logic will bring hidden dangers to the subsequent stable operation of the unit, and the applicability of the above test methods is poor

When it is heavy, it will cause the filter material to harden, which not only affects the normal operation of the filter, but also brings certain economic losses.
