Some of the decisions made over the last 40 years at the Hanford Nuclear Reservation are coming back to haunt the site’s current managers. A new report out this week examined why a double-hulled tank of radioactive waste recently sprung a leak in its inner shell. That has raised the possibility of having to pump out the waste from the tank.
