<p>Abstract: DEH and ETS is important auxiliary systems for turbines, normally DEH and ETS are performed with different type of control system by turbine supplier, and this paper investigates and survey nuclear power plant and in order to get the operation experience, there are information security, maintenance inconvenience, long supply cycle guarantee and high cost problems and so on in DEH and ETS in nuclear power in China. This paper analyzes the problems and try to get the reasons why DEH-ETS has these problems. The DCS technology has been widely used in nuclear power plant in now days, so this paper puts forward a technical solution based on the safety DCS and no-safety DCS platform to realize the DEH and ETS, and according to the analysis of product suitability and engineering test results and implement experience, the system structure and interface has been simplified, no information security problem, and some of the system performances has been improved, and the spare parts can be used in the whole nuclear power plant, so the long supply cycle cost can been reduced, the solution can effectively solve the problems of DEH and ETS, and has a good prospect in the further.</p><p>Key words: Nuclear power plant, Steam turbines, DEH&amp;ETS, Autonomy, Integration, information security</p>

2021 28th International Conference on Nuclear Engineering (ICONE28)

Supporting the need among researchers worldwide for additional online and multimedia content, ASME now offers the ASME Conference Video Collection. This platform will collect and provide long-term access to conference presentation videos, encompassing all technology areas within ASME's technical conference and events program. About 30,000-40,000 engineers across all mechanical engineering and related disciplines participate in ASME conferences each year. This includes authors of approximately 6,000 to 8,000 technical papers published by ASME, the majority of whom also submit video presentations for our virtual conferences. The video collection will be available as an add-on to existing product packages or as a separate subscription.
