Pilgrim Nuclear Decommissioning Raises Long-Term

PLYMOUTH, MA (plimoth)— While the Pilgrim Nuclear Power Station permanently shut down in 2019, its decommissioning continues to present long-term challenges for Plymouth and surrounding communities, with key issues expected to persist through at least 2063.

Local and state officials remain concerned about on-site storage of spent nuclear fuel, delayed federal action, and limits on future land use, all of which continue years after the plant stopped producing electricity.

Nuclear Waste Remains On-Site

Although the reactor is no longer operational, spent nuclear fuel is still stored at the Pilgrim site in reinforced dry casks. These materials are considered secure but remain highly radioactive.

Under federal law, the U.S. Department of Energy is responsible for removing the waste and transferring it to a permanent national repository. However, the United States currently lacks an operational long-term disposal facility, leaving Plymouth as a temporary host for decades.

Federal Responsibility, Local Impact

Town and state leaders argue that Plymouth is carrying a disproportionate burden due to federal delays.

Despite the plant’s closure:

• Security and emergency planning requirements remain in place
• The town must host radioactive material without receiving energy benefits
• Long-term uncertainty complicates municipal planning

Massachusetts officials have repeatedly urged federal agencies to accelerate the creation of a national storage solution, but progress has been limited.

Land Use and Economic Limitations

The presence of spent nuclear fuel significantly restricts full redevelopment of the Pilgrim site, including waterfront and commercial opportunities. While some dismantling and cleanup work is underway, complete release of the property is dependent on waste removal, which may not occur for decades.

Officials say this delay affects:

• Economic development opportunities
• Potential tax revenue
• Long-term land use planning for Plymouth

Decommissioning Timeline

• 2019 – Pilgrim Nuclear Power Station shuts down permanently
• 2020s–2030s – Decommissioning and site cleanup continue
• Through 2063 – Spent nuclear fuel could remain on-site without a federal repository

Community Reaction

Residents remain divided over the situation. Some point to strict safety measures and regulatory oversight, while others express concern over environmental risks and the extended timeline.

Many agree on one point: the lack of a federal solution has left Plymouth in limbo, long after the plant’s closure.
