MHD equilibria of tokamak plasmas with neoclassical current effects (neoclassicalconductivity and bootstrap cttrrent) were calculated self-consistently. Neoclassicaleffects on JFT-2M tokamak plasmas, sustained by ohmic currents, were studied.Bootstrap currents flow little for L-mode type equilibria because of low attainablevalues of poloidal beta, fi,. H??mode type equilibria give bootstrap currents of 30%ohmic currents for p, attained by JFT-2M and 100% for p.>] .5, both of which aresufficient to change the cu?"rent profiles and the resultant MHD equilibria.Neoclassical conductivity whicla has roughly half value of the classical Spitzer conduc-tivity brings peaked ohmic current profiles to yield low safety factor at the magneticaxis. Neoclassical conductivity reduces the value of effective Z(Z.,) which isnecessary to give the observed one-turn voltage but it needs impurities accumulatingat the center when such peaked current profiles are not observed.
