NRC schedules webinars on Holtec’s proposed New Mexico storage site
The Nuclear Regulatory Commission has scheduled four webinars in late August and early September to present its draft environmental findings and receive comments on Holtec International’s proposed consolidated spent nuclear fuel storage facility in New Mexico. Webinars were previously held on June 23 and July 9.
As published in the August 13 Federal Register, the public comment webinars will be held on August 20 from 6–9 p.m., August 25 from 2–5 p.m., August 26 from 6–9 p.m., and September 2 from 11 a.m.–2 p.m. All times are Eastern. Information for the webinars is posted on the NRC’s Public Meetings webpage.

Spatial and temporal spectroscopic measurements in the wavelength range from visible to soft X-ray lights are powerful tools for fusion research. We have constructed absolutely calibrated two-dimensional visible-ultraviolet (V/UV, 2500-7000 Å), Vacuum ultraviolet (VUV, 150-1050 Å) and soft X-ray (SX, 20-350Å) spectroscopic measurement systems for quantitative analysis of impurity ion behavior in the tandem mirror GAMMA 10. Carbon, oxygen and nitrogen ions are main impurity ions observed in the GAMMA 10 plasma. Using absolute emissivities of impurity lines and the collisional-radiative model, impurity ion density profiles are obtained. Moreover, we observed the plasma rotation velocity in order to measure the electric field profile by using V/UV spectrograph in the hot ion mode plasma at the first time. Then, the obtained electric field profile in the central cell is almost equal to the result of beam probe measurements.
