PurposeThis workbook packages NRC daily reactor power percentages as derived daily electrical output (MWe), together with a validated unit-name mapping table and plant metadata. It is designed for programmatic ingestion and reproducible analysis.

METHODOLOGY
10
11
Main calculationPower_MWe = daily_percent_power × capacity_mwe / 100. This produces estimated actual reactor electrical output in MWe. The source NRC power file reports percent of nameplate power; multiplying by capacity MWe converts to absolute electrical output.
12
Why MWe?Electrical output (MWe) is the most widely used unit for grid analysis, generation estimates, and capacity factor calculations. Thermal power (MWt) and percent-of-nameplate values can be recovered using Plant_Metadata lookups — see Python_Examples, example 7.
13
Name mappingEvery reactor column in the power sheet is explicitly mapped to a canonical reactor record. The Unit_Mapping sheet is the authoritative join table for linking power data to plant metadata.

HOW TO USE THIS DATA
16
17
Ingestion pathLoad Power_MWe plus Unit_Mapping. The power sheet is transposed (reactors = rows, dates = columns). For tidy (long) data, transpose and melt using the power_column_name field, then join on Unit_Mapping.power_column_name.
18
Code examplesSee the Python_Examples sheet for seven ready-to-run code snippets covering common workflows: single-reactor queries, fleet snapshots, tidy reshaping, attribute filtering, capacity factor computation, and MWe-to-MWt/percent conversions.
