Division Spotlight
Thermal Hydraulics
The division provides a forum for focused technical dialogue on thermal hydraulic technology in the nuclear industry. Specifically, this will include heat transfer and fluid mechanics involved in the utilization of nuclear energy. It is intended to attract the highest quality of theoretical and experimental work to ANS, including research on basic phenomena and application to nuclear system design.

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.”

In the framework of the radiation protection monitoring around DANE, the high-energy factory of the Istituto Nazionale di Fisica Nucleare-Laboratori Nazionali di Frascati (INFN-LNF), a characterization of the neutron field was performed. As a suitable neutron spectrometer, a specially designed Bonner sphere system, whose energy range was extended up to hundreds mega-electron-volts by means of three spheres equipped with copper or lead inserts, was employed. The response matrix of the system was derived with MCNPX and experimentally validated with reference neutron fields. The neutron spectrum has been unfolded with the FRUIT (FRascati Unfolding Interactive Tool) code, a new unfolding code developed at INFN-LNF for the needs of operational radiation protection. This paper presents the results of the measurements in the DANE complex, underlying the achievements of the new unfolding code. Moreover, the impact of these kinds of measurements on routine radiation protection practices is briefly addressed.
