  New Grad's-Zhdanov module is implemented in the SOLPS-ITER code and applied
to ITER impurity transport simulations. Significant difference appears in the
helium transport due to improved parallel kinetic coefficients. As a result
30\% decrease of the separatrix-averaged helium relative concentration is
observed for the constant helium source and pumping speed. Change of the
impurity behaviour is discussed. For the neon changes are less pronounced. For
the first time the ion distribution functions are studied in the ITER
Scrape-off layer conditions to reveal the origin of the kinetic coefficient
improvements and theory limitations.
