A volume-averaged model of nitrogen-hydrogen plasma chemistry to investigate ammonia production in a plasma-surface-interaction device

Body, Thomas; Cousens, Samuel; Kirby, Juliet; Corr, Cormac


Nitrogen impurity seeding is a promising technique for increasing the radiative power dissipation rate in the edge plasma of a fusion device. It will be required in future fusion devices such as ITER to reduce the directed heat flux on the divertor strike-points to within erosion limits. However, chemical reactions between nitrogen and fuel isotopes may complicate tritium control measures by increasing in-vessel retention and impacting the gas-handling plant. To gain insight into...[Show more]
