      The studies of physical processes occurring in inertial fusion applications commonly use numerical simulation methods. This motivates the development of codes allowing to simulate the characteristics of thermonuclear burning and compression. One of these codes is represented by ALF.
      ALF is a 1-D code for the calculation of two temperature emitting gas including the nonstationary energy, momentum and mass transfer by neutrons and fast charged particles, kinetics of thermonuclear and neutron-nuclear reactions as well as local variations of the ion distribution function.
      The ALF code allows to calculate the following processes:
      - two-temperature gas dynamics in terms of physical viscosity, momentum transfer to material by neutrons and
      - charged particles, energy, release from thermonuclear and neutron-nuclear reactions, variations of mass related to the transport of neutrons and fast charged particles;
      - radiation transfer in the approximation of nonequilibrium spectral quasi-diffusion in terms of Compton scattering;
      - heat transfer by electrons and ions;
      - material heating under the exposure to fast ion flux;
      - kinetics of thermonuclear and neutron-nuclear reactions;
      - transport of fast charged particles (these include both the products of thermonuclear and neutron and recoil nuclei resulting from the elastic scattering on H, D, T, 3He, 4He).
      - neutron transport (the calculations involve the thermal dispersion of TD neutrons and energy distribution of neutrons resulting from nonthermal TD reaction);
      - local variation of the distribution function of thermal ions (H, D, T, 3He, 4He).
      The report contains:
      - a system of differential equations serving the base for the code;
      - results of numerical operation studies for the target proposed for the use within the laser NIF project (USA).
