Availability Notice


The NRC Inventory of Dams has been prepared as required by the charter of the NRC Dam Safety Officer. The inventory lists 51 dams associated with nuclear power plant sites and 14 uranium mill tailings dams (licensed by NRC) in the U.S. as of February 1, 1982.

Of the 85 listed nuclear power plants (148 units), 26 plants obtain cooling water from impoundments formed by dams. The 51 dams associated with the plants are:

  1. located on a plant site (29 dams at 15 plant sites)
  2. located off site but provide plant cooling water (18 dams at 11 additional plant sites)
  3. located upstream from a plant (4 dams) -- they have been identified as dams whose failure, and ensuing plant flooding, could result in a radiological risk to the public health and safety

The dams that might be considered NRC 1 s responsibility in terms of the Federal dam safety program are identified. This group of dams (20 on nuclear power plant sites and 14 uranium mill tailings dams) was obtained by eliminating dams that do not pose a flooding hazard (e.g., submerged dams) and dams that are regulated by another Federal agency.

The report includes the principal design features of all dams and related useful information.
