Demolition blast planned at Hanford reactor site

RICHLAND, Wash. (AP) - Cleanup crews plan to use an explosion to demolish 13-feet-thick concrete walls that housed an experimental reactor on the Hanford nuclear reservation near Richland.

Weather permitting, the blast will go off at 7 a.m. Saturday but it will be unspectacular.

Washington Closure program manager Chris Pearson says there may be a bit of dust. The walls are underground and a blast mat has been placed over the opening.

The Tri-City Herald reports the Plutonium Recycle Test Reactor was built in the 1950s. The reactor was lifted out in January and buried at a Hanford landfill.

Most of the Hanford cleanup along the Columbia River is expected to be completed next year.
