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 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. 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.”

In this paper, in situ tritium measurements and control by laser techniques are presented. It is proposed to use Laser-Induced Breakdown Spectroscopy (LIBS) as an efficient technique to measure the tritium concentration in ablated material. However, LIBS could be limited due to material melting observed during ablation possibly leading to hydrogen losses. Laser ablation is shown to be an efficient process to recover the in vessel tritium if the dust produced during ablation is collected. This could be forbidden if ITER cannot be operated at high pressure. To overcome this difficulty and detritiate remote surfaces, laser heating could be applied since it generates gaseous compounds. However, inward diffusion could be expected leading to burry tritium in bulk material which is a counterproductive action. Finally, all these techniques must be embarked on remote handling system in order to explore and treat large surfaces. Obviously, this carrier is needed for a reliable and an efficient operation of the ITER nuclear facility.
