T-15 (reactor)

The T-15 is a Russian (previously Soviet) nuclear fusion research reactor located at the Kurchatov Institute, based on the (Soviet-invented) tokamak design. It was the first fusion reactor to use superconducting magnets to control the plasma. In the original (circular cross-section with limiter) shape, it had a major radius of 2.43m and minor radius 0.7m.[1]

The T-15 achieved its first plasma in 1988 and operated until 1995. It achieved 1MA and 1.5MW injection for 1 second pulse.[2] It carried out about 100 shots before closing due to lack of funds.[3]

From 1996 to 1998 a series of upgrades were made, in order to conduct research preliminarily for the design work on ITER, which will also use superconducting magnets. The upgrade deals with converting the tokamak to D-shape divertor design with major plasma radius 1.5m.[3][4] However as of the end of 2013, T-15 is still out of service.
