The first phase of the civil construction works for the COMPASS-U project has been completed

The Institute of Plasma Physics of the CAS has completed extensive modifications of the Experimental hall and the Assembly hall belonging to the COMPASS large research infrastructure.As part of these modifications the concrete walls of the Experimental hall were strengthened from 60 cm to 150 cm and an additional floor was installed in the Assembly hall.The building modifications were successfully completed on 28th June 2023 with the issuance of the Building Final Approval.

 

The adaptations of the Experimental hall will allow installation of the new COMPASS-U tokamak including its auxiliary equipment, and the ALIMAT-F scientific device focused on research, development and testing of advanced fusion materials and conventional and innovative concepts of energy exhaust from the so-called divertor.

 
Two original floors and the basement in the Experimental hall were demolished. The newly constructed reinforced basement will support the new tokamak using 64 special anchors. The new tokamak will be approximately 10 times heavier than the original COMPASS tokamak and will generate considerably stronger dynamical forces on the basement during its operation. The 150 cm thick protective walls made of special concrete will fully shield the generated ionizing radiation. In the underground part of the modified walls, new access channels were prepared for the tokamak power supply feeders and the outlets of diagnostic systems, including precisely aligned channels allowing direct observation and measurement of the plasma parameters in shielded rooms. The dismountable part of the west wall and specifically the demountable ceiling have also been strengthened and will continue to allow the highly flexible use of the new COMPASS-U tokamak, including all future modifications and installations that may occur during the expected minimum 30-year lifetime.
 
In the Assembly hall, which surrounds the Experimental hall, the structures under the new sliding heavy concrete doors to the Experimental hall were reinforced and the floor supporting the new power systems was strengthened. The area for the diagnostic and operating systems was also expanded by installation of the 3rd floor.
