KSTAR joins an exclusive club: Tandem shattered pellet injectors now in testing for disruption mitigation

Published:

–Adriana Ghiozzi for US ITER First-of-a-kind experiments have begun at the KSTAR tokamak in Daejeon, South Korea, where two new shattered pellet injectors were installed in October and December. The tandem use of shattered pellet injectors installed at opposite sides of the machine is a first for the technology, which was developed and fabricated at […]

A 61,000 gallon drain tank, part of the US-provided tokamak cooling water system, is lifted into the tokamak complex for installation in the basement.

First US Components Installed in Tokamak Complex

Published:

Three drain tanks were the first  US-supplied components installed in the ITER tokamak complex this past weekend. Two more US-provided drain tanks will be installed later in the construction sequence. The drain tanks are part of the tokamak cooling water system, which will serve as the primary cooling system for the ITER machine. During operation, the […]
