1Municipal Solid Waste net generation is allocated according to the biogenic and non-biogenic components of the fuel; however, all Municipal Solid Waste summer capacity is classified as Renewable.
* = Absolute percentage less than 0.05.
Notes: Totals may not equal sum of components due to independent rounding.
Other: Blast furnace gas, propane gas, other manufactured and waste gases derived from fossil fuels, non-biogenic municipal solid waste, batteries, chemicals, hydrogen, pitch, purchased steam, sulfur, tire-derived fuel, and miscellaneous technologies.
Other Renewable: Wood, black liquor, other wood waste, biogenic municipal solid waste, landfill gas, sludge waste, agriculture byproducts, other biomass, geothermal, solar thermal, photovoltaic energy, and wind.

Operator: Entergy Nuclear Generation Company

Location and Service Territory: Pilgrim is located on a 1,600-acre site in Plymouth, Massachusetts.

Construction Cost: $462.25 million (2007 USD)2

Reactor Descriptions: Pilgrim has a single General Electric Type 3 boiling water reactor that uses low-enriched uranium dioxide with maximum enrichments of 4.6 percent by weight uranium 235 and fuel burnup levels of 48,000 megawatt-days per metric ton uranium.

Cooling System: Pilgrim reactor uses a once-through cooling system that draws from the Atlantic Ocean.
