Digital control system installed at China’s Linglong One
Earlier this month, the first digital control system was put in place at Linglong One, a small modular reactor demonstration project being built at the Changjiang nuclear power plant in Hainan Province. This is the world’s first land-based commercial SMR and is controlled by China National Nuclear Power Co. Ltd., a subsidiary of the China National Nuclear Corporation (CNNC).

An issue of the axial electron heat loss is of a significant importance for mirror-based fusion devices. This problem has been considered in a number of publications but it is still shrouded in misconceptions. In this paper we revisit it once again. We discuss the following issues: 1) Formation of the electron distribution function in the end tank at large expansion ratios; 2) The secondary emission from the end plates and the ways of suppressing it (if needed); 3) Ionization and charge exchange in the presence of neutrals in the end tanks; 4) Instabilities caused by the peculiar shape of the electron distribution function and their possible impact on the electron heat losses; 5) Electron heat losses in the pulsed mode of operation of mirror devices.
