Abstract
A system of nonlinear spinor field and Bianchi type-I gravitational field in presence of a viscous fluid and $\Lambda$ term has been considered. A system of equations for volume scale $\tau$ and energy density $\varepsilon $ has been reduced. The system obtained has been solved for some special cases. It has been shown that the introduction of spinor field to the system radically changes the character of evolution, in particular for some special choice of parameters it leads to the unlimited growth of the energy density at the finite interval of time.
