Reactor N publishes NPPI ($/MWh), the first independent weekly nuclear power pricing index. Built on NRC, EIA-923, and FERC primary sources. Methodology is public.
The nuclear market repriced over the last 18 months. The Microsoft–Constellation TMI restart anchored PJM at ~$100–112/MWh. The Talen–Amazon Susquehanna deal moved baseload comps in the Mid-Atlantic. Hyperscaler PPAs in ERCOT and CAISO are pulling forward conversations that didn't exist 24 months ago.
Existing benchmarks have not kept up. Wood Mackenzie publishes quarterly. BNEF updates 2–4 times a year and restricts how widely its data can be shared. S&P's nuclear feeds run on opaque methodology. Universities are largely locked out; operators get stale numbers; hyperscalers reference whatever leaked last.
Reactor N exists to fix this. One independent weekly $/MWh index, sourced from primary data, with methodology you can audit before you cite.
Reactor N was founded by Tyler — an iOS developer turned data-infrastructure builder, working full-time on this. Background includes shipping the original Reactor N iOS application (App Store, 2025) used by nuclear engineers for fleet-status tracking, and building data pipelines pulling daily from NRC ADAMS, EIA-923, and FERC OASIS.
The product roadmap is shaped by direct conversations with engineers and analysts working in the sector, and with faculty at the country's largest nuclear engineering programs.
