Division Spotlight
Accelerator Applications
The division was organized to promote the advancement of knowledge of the use of particle accelerator technologies for nuclear and other applications. It focuses on production of neutrons and other particles, utilization of these particles for scientific or industrial purposes, such as the production or destruction of radionuclides significant to energy, medicine, defense or other endeavors, as well as imaging and diagnostics.

Vogtle-3 shuts down for valve issue
One of the new Vogtle units in Georgia was shut down unexpectedly on Monday last week for a valve issue that has since been investigated and repaired. According to multiple local news outlets, Georgia Power reported on July 17 that Unit 3 was back in service.
Southern Company spokesperson Jacob Hawkins confirmed that Vogtle-3 went off line at 9:25 p.m. local time on July 8 “due to lowering water levels in the steam generators caused by a valve issue on one of the three main feedwater pumps.”

Heterogeneous nucleation of D2 bubbles at the surface of the cathode is suggested as the cause of difficulties encountered in the reproduction of electrolytic coldfusion experiments. In some experiments, active nucleation centers are present only intermittently leading to a temporary increase in the chemical potential of deuterium in the cathode up to the homogeneous nucleation limit, which is ∼1.2 eV higher. The increased effective mass of electrons, expressed in the electronic specific heat and in the De Haas Van Alphen effect, is considered as a possible cause of cold nuclear fusion, along with the stronger heavy fermion effects directly observed at low temperatures, but localizability of these states remains a problem. Breakdown of the charge invariance of internucleonicforces at very low center-of-mass energies of the order of 1 eV applicable to this form of (non-µ-mesonic) coldfusion, leads to preferential tunneling of neutrons into nearby deuterons, which is suggested as an explanation for the conspicuous absence of neutrons and 3He.
