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 outlines the preliminary conceptual design of a minimum—cost tritium system for a basic ignition experiment whose objective is to produce and control fusion ignited plasmas for scientific study. A system without tritium recycling and tritium reprocessing is envisioned. The fueling requirements can be satisfied by using a tritium storage tank with 20 kCi absorbed in a uranium bed which will be delivered to the facility every month (about 100 ignition pulses). Fueling needs will be supplied by thermal heating of the uranium bed and subsequent gas puffing of the tritium into the tokamak vacuum vessel. A modular vacuum pumping system is considered (6 × 880 ℓ/sec). Tritiated liquid effluents are eliminated by using oilless—bearing pumps. A thin carbon film is applied by glow discharge over the first wall to contain the tritium in the plasma chamber (by saturating the C film). The overall cost of the tritium system is estimated to be less than $3 million.
