U.K., Japan to extend decommissioning partnership
The U.K.’s Sellafield Ltd. and Japan’s Tokyo Electric Power Company have pledge to continue to work together for up to an additional 10 years, extending a cooperative agreement begun in 2014 following the 2011 tsunami that resulted in the irreparable damage of TEPCO’s Fukushima Daiichi plant.

A new 4.6-GHz lower hybrid (LH) current drive (CD) (LHCD) launcher has been successfully developed in the Experimental Advanced Superconducting Tokamak (EAST) to achieve long-pulse high-performance plasma. It is capable of coupling up to 6 MW of LH power into the plasma with a parallel index N// from 1.79 to 2.23. Before manufacturing the launcher, key component mock-ups were fabricated and tested to validate the radio-frequency (RF) design and the process feasibility. Test results show good agreement with the design value. So far, up to 3.5 MW of net LHCD power was injected into the plasma, and long-pulse operation capability has been demonstrated: 1.26 MW and 100.4 s, suggesting that the new launcher can effectively couple the microwave energy into plasma, to drive current and extend the high-performance plasma. In this paper, some of the RF design, construction, testing, and recent experimental results of the new launcher are presented.
