Protesters are planning to gather near the Sagamore Bridge on Memorial Day to highlight concerns about the safety of the Pilgrim nuclear power plant in Plymouth.

The protesters called the current emergency plan in the event of an accident at the power plant unacceptable for those on the Cape.

The protest comes two months after Gov. Deval Patrick wrote the Nuclear Regulatory Commission expressing concerns about the plant. Patrick said he was writing on behalf of 15 southeastern Massachusetts communities.

Patrick said he shares their concerns because of what he called the lack of a "viable evacuation route" off of Cape Cod.

The NRC relicensed Pilgrim through 2032. The plant's operators say it's safe and secure.

Patrick said the NRC should require the plant be decommissioned if it can't comply with safety regulations.
