U.S. nuclear fuel recycling takes two steps forward
Late last week saw two announcements from companies working to recycle used nuclear fuel on a commercial scale, providing welcome news to anyone hoping to see the United States move to unlock the hidden potential of the more than 94,000 metric tons of spent fuel stored at power plant sites around the country.

Neutral beam attenuation has been investigated by the beam emission diagnostic system at LHD which consists of a quartz optical fiber, leading to a spectrometer and an ICCD detector. The spectral resolution and the reciprocal dispersion are 0.21 nm and 1.4 nm/mm, respectively. The behavior of the beam-stopping cross-section derived from the beam emission is consistent with that of the cross-section from the Atomic Data and Analysis Structure (ADAS) database. The intensity of the beam emission decreases with increasing stopping cross-section from the use of heavy ions in a discharge. We have also observed that the measured cross-section of the hydrogen is larger than that of the ADAS calculation.
