ANS is committed to advancing, fostering, and promoting the development and application of nuclear sciences and technologies to benefit society.
Explore the many uses for nuclear science and its impact on energy, the environment, healthcare, food, and more.
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.”

This paper summarizes the work done to update the PACTOLE code, developed for Pressurized Water Reactors (PWRs) to predict the level of activated corrosion products in their cooling loops. The aim is to use it in safety analysis for the International Thermonuclear Experimental Reactor (ITER) project.
In particular the adaptation has focused on the implementation of copper as a new element in the code by using the findings obtained from “ad hoc” experimental tests. The updated release of the code, named PACTITER, has been extensively used to predict in particular the source term inventory of the ITER divertor primary heat transfer system (PHTS) and the related collective dose to the staff in the supporting activities for the Non-Site Specific Safety Report n.2 (NSSR-2).
