33 Hanford Workers Evaluated for Toxic Vapor Exposure in 5 Days

Elevated Radiation Detected near Second Failing Tank at Hanford Nuclear Site: Report
“Six more Hanford workers reported smelling odors in the AP tank farm where officials collected samples Tuesday. Washington River Protection Solutions says crews transported one worker to Kadlec for further evaluation. Doctors treated and released the employee,” said a report.
On April 26, Hanford Challenge stated that a “second high-level nuclear waste [double-shell] tank at the Hanford nuclear site may have failed.”
Elevated Radiation Indicator of Second Double-Shell Tank Failure at Hanford Nuclear Site: Plutonium, Cesium-137 Levels Detected in AY-101 Outer Shell
The group, citing sources inside Hanford, says that above-background levels of Cesium-137, plutonium and a high-beta emitter (likely Strontium-90) all radioactive by-products commonly found in Hanford tanks, were recently measured outside of the primary liner in Tank AY-101, one of the first of the 28 double-shelled tanks built at Hanford about 40 years ago. Those measurements were confirmed to a high degree of certainty, according to Hanford sources. Read more…
“There is litigation the Attorney General has filed to make sure that the federal government is observant to protect these workers. Very important,” said Gov. Inslee.

6 Hanford Tanks Leaking Nuclear Waste: WA Gov

Leaking tanks hold “two-thirds of the nation’s high-level nuclear waste”
Six Hanford underground tanks holding a brew of radioactive and toxic waste at the most contaminated nuclear site in the U.S. are leaking, says Washington Gov. Jay Inslee.
“None of these tanks would be acceptable for use today. They are all beyond their design life. None of them should be in service,” said Tom Carpenter of Hanford Challenge, a Hanford watchdog group. “And yet, they’re holding two-thirds of the nation’s high-level nuclear waste.”
Handford Site sits on 586-square-miles of shrub-steppe desert in southeastern Washington State, bordering the Columbia River. Six underground tanks are leaking radioactive waste.

The tanks, built in the the 1940s with intended life span of 20 years, hold at least 53 million gallons (200 million liters) of highly radioactive waste, the leftover from plutonium production used in nuclear weapons.
State officials announced last week that one of Hanford’s 177 tanks was leaking up to 300 gallons a year, posing a risk to groundwater and rivers.
Gov Inslee said he had received the “very disturbing news” during meetings Friday that in fact six tanks are leaking.
The authorities say they haven’t yet detected higher radioactivity levels at nearby monitoring wells.
Hanford, home to several tribes of Native Americans and a small agricultural community in the state of Washington, was depopulated in 1943 along with the town of White Bluffs to make room for the nuclear production facility known as the Hanford Site.
