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
Operations & Power
Members focus on the dissemination of knowledge and information in the area of power reactors with particular application to the production of electric power and process heat. The division sponsors meetings on the coverage of applied nuclear science and engineering as related to power plants, non-power reactors, and other nuclear facilities. It encourages and assists with the dissemination of knowledge pertinent to the safe and efficient operation of nuclear facilities through professional staff development, information exchange, and supporting the generation of viable solutions to current issues.

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.”

ITER cryogenic system is in its final design phase to be constructed at Cadarache, South of France. It shall use the most advanced cryogenic technologies developed for accelerators projects adapted and optimized to fulfil the requirements and constraints of a large fusion installation.A refrigeration capacity equivalent to 65 kW at 4.5 K is planned for the cooling of superconducting magnets, their HTS current leads and small users. It also includes the cooldown of the cryogenic pumps and their re-cooling after regeneration. A 1300 kW nitrogen plant provides cooling power for the thermal shields. The key design requirement is the capability to cope with large pulsed heat loads deposited in the magnets due to magnetic field variations and neutron production from the fusion reaction.The cryogenic distribution system is based on the design of a complex and compact transfer line system and several cryogenic distribution and feed boxes.After recalling the basic features we shall present the status of the design and the main magnet interfaces and key design requirements.
