The U.S. Army Corps of Engineers (USACE), Baltimore District, has released the draft Environmental Assessment (EA) and draft Finding of No Significant Impact (FNSI) for the proposed action to decommission and dismantle the Deactivated Stationary Medium Power Model 1A Nuclear Power Plant (SM-1A) at U.S. Army Garrison Alaska, Fort Greely, and release the property for unrestricted use.

The draft EA and draft FNSI are available for a 30-day public review and comment period, Feb. 26, 2021 through March 28, 2021, and can be viewed in a Virtual Public Meeting Room. The Virtual Public Meeting Room will enable the community to review documents, learn about the proposed action, and submit comments. Downloadable versions of the documents and additional information are also available on the SM-1A website.

The draft EA and draft FNSI are also available in physical form at the following locations:

  • Delta Community Library, 2291 Deborah Street, Delta Junction, AK 99737

The purpose of the Proposed Action is to safely remove, transport, and dispose of all materials and equipment, structures, and residual contamination associated with SM-1A; release the SM-1A site for unrestricted use in accordance with radiological dose criteria established by the Nuclear Regulatory Commission (NRC) in 10 CFR 20.1402 and adopted by the Army; and terminate the U.S. Army-issued SM-1A decommissioning permit.

SM-1A was constructed between 1958 and 1962 and operated from 1962 to 1972. Following the reactor’s final shutdown in 1972, the highly radioactive nuclear fuel was removed and disposed of, minor decontamination was performed, and SM-1A was placed into a safe storage (SAFSTOR) configuration. The decommissioning of a nuclear reactor is required within 60 years of permanent completion of operations in accordance with U.S. Nuclear Regulatory Commission (NRC) regulations and the Army Reactor Program. Therefore, the decommissioning of SM-1A must be completed by 2032.

Baltimore District is home to the Corps’ Radiological Health Physics Regional Center of Expertise and brings with them decades of experience working on a broad array of projects around the world, including prior reactor decommissioning projects.
