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.”

The aim of this study is to propose initiating threats and their bounding groups in order to identify initiating cyber threats, and to further apply the initiating threats to cyber risk assessment in nuclear power plants (NPPs). NPP are generally thought to be secure from cyber-attacks, as the control/monitoring network and business network in a NPP are separate from the external network. However, consecutive incidents at nuclear facilities have revealed the necessity of cyber risk assessment for NPPs. To determine initiating threats and their bounding groups for NPP, Operational experience report (OER) and repository of industrial security incidents (RISI) database were utilized. Each of the chosen incidents was documented with descriptions based on the following five characteristics: 1) type of attacker, 2) intentionality, 3) access method, 4) access type, and 5) purpose of the attack. The proposed organization of initiating threats and their bounding groups for NPPs represent a valid first attempt to determine such threats based on actual industrial incidents. This advance can also be further applied to describe scenarios and models of NPP cyber-risk assessments.
