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.

An FM reflectometer is developed to measure the density profile of the MP2 device. It operates in the frequency range of 7.78-12.38 GHz. Phase information is obtained by digitizing the IQ detector outputs. However, the measured signal is significantly contaminated by noise due to microwave reflection at various points because the emitting and receiving antennas are installed outside of the vacuum window. A center aligned Fourier transform is used to remove the noise and extract the correct phase information from the measurement. In this paper, data analysis techniques are introducedplasma density profile is shown.
