Zhongneng Jukong and Fusion Diagnostics: From a Single Discharge to Continuous Operation, How Measurement Systems Affect Device Performance

After a fusion device completes a discharge, researchers must first answer what actually happened in that experiment: how temperature and density changed, where the input energy flowed, whether instabilities appeared in the plasma, and which conditions should be adjusted for the next experiment. These judgments must be built on diagnostic data. As devices advance toward longer pulses and higher parameters, measurement systems must also take on a new task——providing information that can support control decisions in a timely manner before the experiment has ended. Anhui Zhongneng Jukong Technology Co., Ltd. operates precisely at this link connecting detection, computation, and device operation. Founded in 2022, the company focuses on test and measurement systems and...

MEPhI Develops Diagnostic Methods for Reactor and Chip Overheating Prevention

Recently, the team from the Laboratory of Thermal Hydraulics and Boiling Physics at the Moscow Engineering Physics Institute (MEPhI) proposed an early diagnostic method for heat transfer crisis based on the analysis of temperature fluctuations on heat-dissipating surfaces, which enables accurate prediction before dangerous boiling phenomena occur, thereby significantly enhancing the safety margin and economic efficiency of nuclear power plants. It is known that in the operation of pressurized water reactors such as VVER, if bulk boiling occurs in the reactor core, it can easily trigger a heat transfer crisis and lead to fuel element melting; therefore, operating nuclear power plants typically adopt a conservative underload operating strategy. Laboratory Director Kirill Kutsenko pointed out that this research, by establishing the correlation between coolant pressure, flow rate...
