+# Natrium Reactor
+
+## Overview
+
+345 MW electric sodium-cooled fast reactor coupled to a 1 GWh molten salt energy storage system. Developed by TerraPower with DOE ARDP funding.
+
+## Technical Specifications
+
+- **Base output:** 345 MW electric (constant)
+- **Peak output:** 500 MW electric for 5.5 hours
+- **Storage:** 1 GWh molten salt thermal storage (borrowed from concentrated solar power industry)
+- **Reactor type:** Sodium-cooled fast reactor
+- **Load-following capability:** Reactor runs at constant power while storage system enables variable grid output
+
+## Design Intent
+
+- **Original purpose:** Complement intermittent renewables (solar/wind) through load-following capability
+- **Design timeline:** Pre-2020 (before AI demand wave)
+- **Retrofitted application:** AI datacenter power with training cycle variability
+
+## Economics
+
+- **Total cost:** ~$4B for first unit at Kemmerer
+- **Cost per GW:** ~$11.6B/GW (based on 345 MW base capacity)
+- **Funding:** DOE ARDP 50/50 cost-sharing (up to $2B DOE contribution)
+
+## Commercial Deployments
+
+- **Meta:** 8 units (agreement signed January 9, 2026)
+- **Google/Microsoft:** 2.5-3 GW through NextEra-TerraPower partnership (April 8, 2026)
+
+## Technology Heritage
+
+- **Molten salt storage:** Explicitly borrowed from concentrated solar power (CSP) industry
+- **Storage architecture:** Same technology used in solar thermal plants, adapted for nuclear heat input
+
+## Timeline
+
+- **2006** — TerraPower founded
+- **2020** — DOE ARDP funding selection
+- **2026-03-04** — NRC construction permit issued (first for commercial-scale advanced nuclear)
+- **2026-04-23** — Groundbreaking at Kemmerer, Wyoming
+- **2030** — Target first power
+
+## Regulatory Significance
+
+First commercial-scale advanced nuclear plant to receive NRC construction permit. NRC safety review completed ahead of schedule and 11% under budget, demonstrating regulatory pathway for subsequent advanced reactor projects.
