Potential applications of microbial genomics in nuclear non-proliferation

Area of Science:

• Nuclear Science and Engineering
• Environmental Microbiology
• Biogeochemistry

Background:

• Global energy demands necessitate nuclear technology advancements, increasing the need for robust non-proliferation safeguards.
• Current methods for detecting nuclear proliferation are limited to known facilities, leaving a critical gap in monitoring unknown locations.
• Microorganisms inhabit nuclear environments, influencing radionuclide behavior and potentially indicating nuclear activities.

Purpose of the Study:

• To explore the potential of microbiomes as indicators of nuclear activities.
• To address the limitations in detecting nuclear proliferation beyond declared sites.
• To investigate how nuclear processes shape microbial communities for safeguard applications.

Main Methods:

• Review of existing studies on microbial interactions with radionuclides and nuclear environments.
• Analysis of microbial genomics and machine learning applications in environmental monitoring.
• Hypothesizing the existence of characteristic microbiomes linked to nuclear fuel cycle facilities.

Main Results:

• Microbial communities are known to interact with radionuclides and inhabit nuclear sites.
• Nuclear activities can influence microbial community structure and function.
• Geochemical-microbial interactions at nuclear facilities may create unique, identifiable microbiomes.

Conclusions:

• Characteristic microbiomes associated with nuclear activities offer a novel approach for non-proliferation safeguards.
• These microbiomes can inform environmental sampling strategies and biosensor development.
• Further research into nuclear-specific microbiomes can enhance the detection of undisclosed fuel cycle activities.
