On December 20, 1951, Experimental Breeder Reactor No. 1 (EBR-1) became the first power plant to produce electricity using atomic energy. It is now a historic landmark and is open to the public from Memorial Day weekend through Labor Day weekend — seven days a week — from 9 a.m. to 5 p.m. Admission is free.



For visitor access or badging at INL, you will need to provide positive proof of identification such as a current U.S. passport or REAL ID Act-compliant state’s driver’s license. On March 30, 2015 Idaho was granted an extension for REAL ID Act implementation by the Department of Homeland Security (DHS). Therefore, Idaho driver’s licenses are a valid form of ID for accessing INL facilities.

For States/Territories not in compliance with REAL ID Act, a current driver’s license along with a second form of ID such as a social security card, original or certified copy of a birth certificate, Native American tribal document or U. S. Citizen ID Card, can be permitted for badging and visitor access to INL/BEA and other site contractor facilities.

Holders of other REAL ID Act non-compliant state’s driver’s licenses will require additional identification from the Department of Homeland Security, Transportation Security Administration. Click here to to view the list of approved Identification items.
