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.

Measurements of He, 3He/4He, Ne and 13 other components (H2, HD, D2, CH4, H2O, HDO, D2O, N2, CO, C2H6, O2, Ar, and CO2) in four samples of gas from SRI International (SRI) are reported. Three samples were collected from SRI Case-type stainless steel cells containing ~10 g of Pd/C catalyst initially loaded with ~3 atm D2 at ~200°C, and the fourth sample (not identified) was stated to be a control. Case and the SRI researchers have claimed to observe 4He in concentrations of ~100 parts per million (ppm) and up to 11 ppm, respectively, produced in these cells via the fusion reaction D + D = 4He + 23.8 MeV. Others found no evidence for 4He addition that cannot be readily explained by leaks from the atmosphere into the SRI cells. One sample appears to be identical in composition to air, and the other three have been seriously affected by leak(s) into and from the SRI cells. The rare gas "forensic" evidence includes 3He/4He ratios and He and Ne concentrations that are almost identical to air values. The samples also show high N2 (a primary indicator of air), low O2, and high CO and CO2 due to reaction of incoming atmospheric O2 with C in the catalyst. In two samples, the original D2 (or H2) has almost completely disappeared by outflow through the leak(s). These results have obvious implications concerning the validity of the excess 4He concentrations claimed by Case and the SRI researchers.
