Reducing Hanford’s Greenhouse Gas Emissions

When you think of the Hanford Nuclear Reservation, its radioactive legacy usually comes to mind. But, as correspondent Courtney Flatt reports, there’s more to clean up than just the site’s nuclear waste.

The Department of Energy wants to cut back commuter traffic at the nation’s most contaminated nuclear site.

Nearly 10,000 workers travel to and from Hanford on a daily basis. That’s a lot of traffic, and most of those cars hold just one person.

RICHLAND, Wash. – At the Hanford Nuclear Reservation in southeast Washington, the race is on to clean up radioactive sludge buried in aging underground tanks. Some of that waste has already leaked into the soil not far from the Columbia River. But attempts to use high-tech robotics to hose out waste tanks haven't gone as planned. And an important federal cleanup deadline is fast approaching. Correspondent Anna King visited one Hanford tank farm to see what’s causing the delays.

RICHLAND, Wash. – Over the last two years we’ve brought you numerous stories about high-level whistleblowers at the Hanford Nuclear Reservation's nuclear waste treatment plant. It’s one of the largest environmental cleanup projects on Earth. Now, yet another top expert there is risking his career to speak openly. He tells our correspondent Anna King the plant’s vessels and pipes -- as they’re designed now -- will leak radioactive waste within their planned lifespan.
