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.

Energy distribution of the 14.7MeV protons, which has energy spread of about 2 MeV due to the thermal motion of fuel ions, is derived analytically. Curvature drift of charged particles in an open magnetic field with a spiral configuration is estimated for separation of the 15MeV protons from thermal components. Numerical orbital calculation shows that amplitude of a wave about 1MV is necessary for trapping and deceleration of the proton beam in a traveling-wave direct energy converter (TWDEC). About 80% of the kinetic energy of the proton beam can be converted into electricity when bunching of the proton beam is improved by applying series of velocity modulations. Results of a computer simulation show that the TWDEC has desirable performance characteristics. The traveling wave with a designed frequency is excited spontaneously without any external power supply. The wave rapidly reaches an equilibrium state after loading, and stably responds to load fluctuations.
