Abstract

The conceptual project of the construction of the cryostat and vacuum chamber was prepared, which are two of the main components of the compact tokamak with reactor technologies. The main technical solutions of the construction were decided, such as its configuration, technical characteristics, and operating regimes of its components. Conceptually, the cryostat is a single-wall cylindrical vacuum chamber made from austenitic stainless still that contains the superconducting electromagnetic system, the vacuum chamber, and the thermal protection of the cryostat and the vacuum chamber. The maximum diameter of the cryostat is of 12 m, its height is of 11 m, and its mass is of 317 t. In the cryostat, vacuum of 1 × 10–4 Pa can be established. The vacuum chamber is an all-welded double-wall construction made from austenitic stainless still. Its inner and outer shells are connected by a set of toroidal and poloidal stiffening ribs, in the space between which borated water is circulating. The sickness of the shells and of the stiffening ribs is of 25 mm. The outer diameter of the chamber is of 6.64 m and its height is of 3.85 m.
