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.”

A follow-up is done to earlier work on the conversion of isotopic waters to hydrogen isotopes, and it involves the reaction behavior of water vapor with Zr(V0.5Fe0.5)2 getter alloy under water vapor flow conditions. The efficiency of the alloy, for the conversion of H2O and D2O to H2 and D2, respectively, has been measured at different reactor pressures in the range of 10 to 330 Pa for different alloy temperatures in the range of 150 to 400°C and with hydrogen and oxygen concentrations in the alloy ≤ 250 mmol/mol of alloy. The conversion efficiency was measured to be in the range of 25 to 35% at reactor pressures of ≈250 Pa for water vapor flow rates of ≈0.3 µmol/g of alloy per second, while it was found to be in the range of 70 to 80% at reactor pressures ≤20 Pa with flow rates of ≤0.02 µmol/g of alloy per second. These experiments demonstrate the feasibility of tritiated water vapor conversion to tritium using metallic getter alloys under quasi-steady-state conditions; this feasibility is very relevant to the fusion reactor fuel cycle.
