Status of the project of NICA accelerator complex, which is under construction at JINR (Dubna, Russia), is presented. The main goal of the project is to provide ion beams for experimental studies of hot and dense baryon-ic matter and spin physics. The NICA collider will pro-vide heavy ion collisions in the energy range of √sNN=4/11 GeV at average luminosity of L=1.1027cm−2·s−1 for 197Au79+ nuclei and polarized proton collisions in energy range of √sNN=12/27 GeV at lumi-nosity of L ≥ 1031cm−2·s−1. NICA accelerator complex will consist of two injector chains, 578 MeV/u supercon-ducting (SC) booster synchrotron, the existing SC syn-chrotron (Nuclotron), and the new SC collider that has two storage rings each of 503 m circumference. Con-structing facility is based on Nuclotron-technology of SC magnets with iron yoke. Hollow SC cable cooled by two-phase He-flux used for operation with 10 kA currents and 1Hz cycling rate. Both stochastic and electron cooling methods are used for the beam accumulation and its stability maintenance.
