The Coast Guard removes security zones from a closed nuclear plant

The Coast Guard is removing the safety and security zones around the Pilgrim Nuclear Power Plant in Plymouth, Massachusetts. The plant stopped producing power, so the special rules for boats and ships around it are no longer needed.

For decades, nuclear power plants have had strict security perimeters, restricting access for boats and other vessels. This small change means that a piece of coastal water, previously off-limits, is now open again. It marks one more step in the long, slow process of decommissioning a nuclear site, which can take decades.
