How NuclearSignal works
NuclearSignal aggregates public nuclear energy data from official US government sources, processes it with AI to extract signal from noise, and delivers structured intelligence to subscribers.
Data sources
NRC Event Notifications
10 CFR 50.72 requires nuclear plant operators to notify the NRC within 4–8 hours of certain events: unplanned shutdowns, safety system actuations, loss of offsite power, and other reportable conditions. NuclearSignal pulls these daily.
NRC ADAMS (Agencywide Documents Access and Management System)
The NRC's public document management system contains inspection reports, license amendment requests and approvals, safety evaluations, enforcement actions, and all formal NRC correspondence. We index recent filings daily and rank by significance.
DOE Office of Nuclear Energy
Press releases covering SMR program funding, advanced reactor demonstration projects, loan guarantees, research grants, and policy announcements from the Department of Energy.
World Nuclear News
The global nuclear industry's primary trade wire, covering reactor operations, uranium market developments, international policy, and SMR project updates worldwide.
AI analysis
Each item is processed by Claude (Anthropic) to extract structured fields: the entity involved, what happened, why it matters, and an impact score (low / medium / high). Relevance scores are generated for four audience types: utility operators, investors, policy teams, and SMR sector participants.
Update cadence
Scrapers run daily. NRC Event Notifications are checked every 24 hours. ADAMS is indexed for documents from the past 3 days. Weekly digest emails are sent every Monday morning.
What NuclearSignal is not
NuclearSignal is a monitoring and intelligence service, not a safety authority. All source data is public and official. For safety-critical decisions, always refer directly to the NRC and official regulatory documents.
