All 2,554 seats on free public tours of the Hanford nuclear reservation in 2012 were claimed Tuesday morning five hours and 15 minutes after registration opened.
That sets a new record for the current system that opens registration for all seats for the year at once. Last year, it took eight hours and three minutes for all seats to be claimed.
Registration for the public tours opened at 12:01 a.m. Tuesday, with registration only available on the internet. In the first five minutes, half the seats were reserved, said Cameron Hardy, Department of Energy spokesman. By 12:45 a.m., more than 2,100 seats were taken.
Those still hoping to go on a tour this year still could grab a seat if they watch the internet registration site for cancellations.
Never miss a local story.
When cancellations are received, open seats are posted without notice at hanford.gov.
Tours just of Hanford's historic B Reactor also will be offered this year, but registration has not been announced yet.
