Division Spotlight
Accelerator Applications
The division was organized to promote the advancement of knowledge of the use of particle accelerator technologies for nuclear and other applications. It focuses on production of neutrons and other particles, utilization of these particles for scientific or industrial purposes, such as the production or destruction of radionuclides significant to energy, medicine, defense or other endeavors, as well as imaging and diagnostics.

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).

The present paper compares, in terms of safety and reliability, two different designs for tritium recovery from DEMO Pb-17Li water-cooled blanket. The first one, based on tritium recovery from Pb-17Li outside the blanket units, tritium removal from the purge gas of the extracting system and tritium permeation barriers towards the coolant, is overviewed and analyzed especially with regard compactness and reliability. In the alternative option, tritium generated in the blanket is free to permeate into the cooling water and is recovered by the water detritiation system, avoiding, therefore, the external tritium extractor from Pb-17Li and permeation barriers, the technological feasibility of which is not yet proven on industrial plant scale. A safety analysis of this alternative design has been carried out both for normal operation and accident conditions. The results, here presented and discussed, have shown that this alternative option seems to be feasible and worthy of successive research and investigations.
