	Basic goal of the planned NICA facility at JINR is focused on the studying of heavy ion collisions over the energy range √s ~ 411 GeV/u. Capabilities of the proposed scheme were carefully analyzed in this case and reaching of the desired average luminosity, L = 1·10²⁷ cm^-2 s⁻¹ for gold-gold collisions at √s = 9 GeV/u, have been confirmed. The other important NICA research domain is the experiments with polarized proton beams at the highest possible energy, the highest luminosity and polarization degree as well. The main aim is to provide √s ~ 25 GeV and L ~ 1·10³¹ cm^-2 s⁻¹. The unsolved aspects of the problem are discussed, possible solutions are analyzed and necessary modifications of the NICA scheme are considered as well.

	The Nuclotron-based Ion Collider fAcility (NICA) is a new accelerator complex being constructed at JINR aimed to provide the collider experiments with ion-ion (Au⁷⁹⁺) and ion-proton collisions at the energy range of 1-4.5 GeV/n and also the collisions of polarized proton-proton and deuteron-deuteron beams. Superconducting collider rings accumulate beam injected from Nuclotron and realize the conditions for beam-beam interactions to achieve the required luminosity. Each ring has the racetrack shape with two arcs and two long straight sections. Its circumference is about 500 m. The collider lattice design is subjected to have possibility of the gamma transition variation, mainly by the arcs retuning. The long straight sections contain the most of the insertion devices and are matched to the arcs, optimized to provide the final focusing of the beams in IP and accurate betatron tune adjustment.

	The NICA facility being constructed at JINR will consists of two synchrotrons (Booster and Nuclotron) and collider working at constant magnetic field. To reach required luminosity level the collider rings will be operated with short ion bunches. The bunch formation in the collider as well as longitudinal dynamics in all the rings is described. The parameters and preliminary design of RF systems are presented.

	The Nuclotron upgrade – the Nuclotron-M project, which had been started in 2007, involved the modernization of almost all of the accelerator systems, using beam time during seven runs devoted to testing newly installed equipment. Following the project goals, in March 2010 Xe ions were accelerated to about 1.5 GeV/u. In December 2010, the stable and safe operation of the magnetic system was achieved with a main field of 2 T. The successful completion of the project paves the way for further development of the Nuclotron-based Ion Collider fAcility (NICA).

NICA accelerator complex will consist of two linear accelerators, two superconducting synchrotrons, two superconducting storage rings of the collider and transport beamlines. Geometry and magnetic system of NICA beamlines are presented in this report. Results of beam dynamics simulations within the beamlines are considered.
