Division Spotlight
Aerospace Nuclear Science & Technology
Organized to promote the advancement of knowledge in the use of nuclear science and technologies in the aerospace application. Specialized nuclear-based technologies and applications are needed to advance the state-of-the-art in aerospace design, engineering and operations to explore planetary bodies in our solar system and beyond, plus enhance the safety of air travel, especially high speed air travel. Areas of interest will include but are not limited to the creation of nuclear-based power and propulsion systems, multifunctional materials to protect humans and electronic components from atmospheric, space, and nuclear power system radiation, human factor strategies for the safety and reliable operation of nuclear power and propulsion plants by non-specialized personnel and more.

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.”

Even with the two Spent Fuel Pool (SFP) reracking projects to expand the capacity to 4398 cells, Kuosheng Unit 1 had practically no unfilled SFP cells such that operation was prohibited from November 30, 2016. After a careful evaluation of the possible measures to restore refueling ability, the Taiwan Power Company has elected to install four 11?10 storage racks within the Cask Loading Pool. The additional 440 cells could allow operation for two more fuel cycles, about 3 more years. All the aspects (criticality, thermal-hydraulic, structure, radiological, and accident) specified in the Republic of China Atomic Energy Council’s review guidance are evaluated. Additionally, distinctive subjects such as transportation, installation, post-Fukushima safety enhancement measures, and emergency/recovery plans are thoroughly addressed. The Safety Analysis Report (SAR) was submitted in August 2016. As the safety issues were thoroughly examined, many unique and significant issues worth exploring have been identified and additional analyses requested. After all the issues resolved, the SAR was approved in April 2017. For Unit 1, rack installation was completed and the unit was back online in June 2017. The timely and successful implementation of this contingency project is extremely critical for achieving a stable power supply in Taiwan.
