Division Spotlight
Nuclear Criticality Safety
NCSD provides communication among nuclear criticality safety professionals through the development of standards, the evolution of training methods and materials, the presentation of technical data and procedures, and the creation of specialty publications. In these ways, the division furthers the exchange of technical information on nuclear criticality safety with the ultimate goal of promoting the safe handling of fissionable materials outside reactors.

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.”

An explanation is proposed for the time dependence of the neutron emission transient observed after interrupting the electrolysis in Fleischmann-Pons-type experiments with titanium cathodes. It is suggested that the time structure of the neutron emission is related to a reduction of active volume (i.e., the volume with a loading ratio higher than the critical value necessary for cold fusion to take place) in the deuterated titanium. This reduction occurs during the postelectrolysis time due to deuterium transport from the TiDx delta-phase layer to the undeuterated bulk of the cathode. Calculations of the active volume decrease are done by using the Wagner model.
