Manhattan Project B Reactor Tours
Shorter tours visit only the B Reactor, the world's first large-scale nuclear reactor. Like the site tours, advance reservations are necessary; 50 tour dates per year between April and September, including most weekends. Groups will get about two hours on site, plus 45 minutes each way on a chartered bus to reach the isolated facility. Unlike the full site tours, there is no citizenship requirement, but photo ID is mandatory.
Hanford Site Tours
Five-hour tours of the Hanford Nuclear Site with stops at the historic B Reactor, the Environmental Restoration Disposal Facility, the Waste Treatment Plant construction zone. April through September only, and always on weekdays. Reservations required on a first come-first serve basis â registration for the year's tours opens in early March, and often fills in less than a day. Cancellations will open up a few slots, particularly later in the season, but you'll need luck to catch them when they happen: no waiting list. This tour is only open to U.S. citizens.
