  Nonextensive statistics has attracted attention as a description of particle
spectra in nuclear collisions at QCD energies. First, we construct the equation
of state by incorporating Tsallis statistics based on the hadron resonance gas
and parton gas models. Thermodynamic conditions are found to impose constraints
on the $q$-parameter of Tsallis distribution. Next, we apply the equation of
state to the relativistic hydrodynamic modeling of nuclear collisions. The
Cooper-Frye prescription is consistently modified. Numerical demonstrations
indicate that the model may describe charged particle spectra at Large Hadron
Collider in the transverse momentum range up to 6-8 GeV. Elliptic flow, on the
other hand, suggests a narrower range of applicability.
