Uranium Fuel Inventory and Nuclear Refueling Schedules

This dataset provides detailed, up-to-date information on uranium fuel inventory, enrichment levels, refueling outage schedules, and spent fuel pool storage for pressurized and boiling water nuclear reactors. It enables operational planning, regulatory compliance, and risk assessment for nuclear fuel management across multiple reactor sites.

Behind this dataset

Same schema. As many rows as you need.

These 100 rows came out of a blueprint — 19 columns with generation rules behind each one. Open it in Data Factory to retune a column, add your own, wire in foreign keys, and run it at the size you actually need.

Rules it was built with
  • Nuclear plant name and reactor type (PWR or BWR)
  • Fuel assemblies on-site and in-core vs. spent fuel pool
  • Uranium enrichment level (% U-235), typically 3-5% for commercial reactors
  • Refueling outage schedule: 18-24 month cycle typical
  • Fuel burnup (GWd/MTU - gigawatt-days per metric ton uranium)
  • Fresh fuel receipts and spent fuel discharges
  • Spent fuel pool capacity and dry cask storage
  • Nuclear fuel cost ($/MWh) amortized over fuel cycle
