Recent results of massively parallel kinetic (PIC/MC) simulations of the tokamak scrape‐off layer are discussed. It is demonstrated that a number of well studied properties of the low‐recycling divertor plasma, such as the sound speed and the average energy of plasma particles impinging on the divertors, cannot be generalized to the high recycling case. A new analytical model for plasma boundary condition has been derived (© 2012 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
