Windsor, Connecticut, Site

Background

The Windsor, Connecticut, Site was remediated under the Formerly Utilized Sites Remedial Action Program (FUSRAP) and under U.S. Nuclear Regulatory Commission (NRC) regulations. FUSRAP was established in 1974 to remediate sites where radioactive contamination remained from Manhattan Project and early U.S. Atomic Energy Commission operations.

History

While under contract with the U.S. Atomic Energy Commission (AEC) from 1955 to 1962, the former Combustion Engineering (CE) site was used to research, develop, and manufacture nuclear fuel; to develop, design, and fabricate fuel-element subassemblies for submarines; and to construct and operate the S1C test reactor facility for the U.S. Navy. From the early 1960s to 2000, other non-AEC commercial nuclear fuel operations and related radiological services were performed under NRC license at the CE site.

In 1994, U.S. Department of Energy (DOE) determined that certain areas of the property were eligible for remedial actions under FUSRAP. Congress assigned responsibility for FUSRAP cleanup activities to the U.S. Army Corps of Engineers (USACE) in 1997. Between 1998 and 2007, USACE performed site characterization and remedial investigation fieldwork and published risk assessment and feasibility study reports for the FUSRAP-eligible areas of the site. Because of the extensive commingling of FUSRAP-related materials with NRC-regulated materials, CE, NRC, USACE, and DOE agreed that CE would conduct the decommissioning of the site under NRC regulations.

Remediation of the FUSRAP areas began in 2009 and was completed in 2011. The Windsor Site Closeout Report documenting the completion of the FUSRAP remedial actions was finalized by USACE in January 2017. In January 2019, USACE transferred long-term stewardship FUSRAP responsibility for the Windsor site to LM.

Final Conditions

The Windsor site is privately owned. The cleanup activities performed at the Windsor site allow for unlimited use and unrestricted exposure.

No monitoring, maintenance, or site inspections are required for the Windsor site. LM’s long-term surveillance and maintenance responsibilities consist of managing site records and responding to stakeholder inquiries.
