Emergency declared at US Hanford nuclear waste site after tunnel collapse

The US Department of Energy has declared an emergency at the Hanford, Washington nuclear waste storage site, after a cave-in of a tunnel used to store radioactive materials and equipment.

約3000人の労働者が広大な複合施設の200 East Areaで避難し、現地時間10時半までには避難命令はサイト全体に拡大された。
About 3,000 workers have taken cover at the 200 East Area of the sprawling complex, local media reported. By 10:30 am local time, the “take cover” orders have been expanded to the entire site, which is about half the size of Rhode Island.

プルトニウム - ウラン抽出工場近くのトンネルの一部が火曜の早朝崩落した
A portion of a tunnel near the plutonium-uranium extraction plant (PUREX) collapsed early Tuesday morning local time, most likely from vibrations produced by nearby road work, KING-TV reported.

当初の報告では1.2mの穴とされたが、その後6mに広がった。場所は1960年代に放射能の強い物資や器具を保管するために使われた二つのトンネルの分岐点
Initial reports spoke of a 4-foot (1.2 meter) hole, which was later expanded to 20 feet (6 meters) across, at the junction of two tunnels used in the 1960s to store highly radioactive materials and equipment, such as trains used to transport nuclear fuel rods.

The PUREX facility was built in the 1950s and used until 1988 to extract plutonium from around 70,000 fuel rods in total. The building has been vacant for nearly twenty years and “remains highly contaminated,”according to the Hanford website. Rail cars used to transport the fuel rods from the nuclear reactors to the processing facility are buried inside the nearby tunnels.

労働者に怪我人はなく、ワシントン州当局によれば放射性物質の放出はない。
No workers were injured in the collapse, and officials have detected no release of radiation, Washington state Department of Ecology spokesman Randy Bradbury told AP.

1960年代に使用済み燃料棒が軌道貨車に積まれ、貨車は丘の側に掘られたトンネル内に送られた。21台の貨車がこのトンネルに詰まっている。
“In the ‘60s, spent fuel rods were put in railroad cars and, once filled, the railroad cars were wheeled into a tunnel dug into the side of a hill,” Bradbury said. “Twenty-eight rail cars in all fill this particular tunnel. A worker today noticed a collapse of dirt above the tunnel today, triggering the evacuation.”

労働者は屋内にとどまり飲食をしないよう命じられた。緊急隊員が避難を組織している。
Workers at the complex have been ordered to stay indoors and refrain from eating and drinking, according to text alerts seen by local media. Emergency crews are organizing the evacuation.

トンネルを覆う土の沈下の恐れがある。
Emergency measures were put in place due to “concerns about subsidence in the soil covering railroad tunnels,” says a statement posted on the Hanford facility website.

Residents of the nearby Benton and Franklin counties do not need to take any action, the facility said.

Hanford is located on the Columbia River in eastern Washington, near the border with Oregon. Built during World War Two as part of the Manhattan Project to develop the nuclear bomb, it still contains roughly 53 million gallons – over 2,600 rail cars – worth of high-level nuclear waste, left from the production of plutonium for the US nuclear weapons program.

A number of current and former Hanford workers suffer from serious medical conditions as a result of exposure to toxic waste leaks and “burps” of radiation at the complex, RT America reported in April 2016.
