The collapse of a tunnel at the massive nuclear waste dump at Hanford,

Washington, 200 miles east of Seattle, has sent shock waves through a nuclear power industry already in the process of a global collapse.

Hundreds of workers were told to "take cover," and to refrain from eating or drinking anything while in the area. Department of Energy Secretary Rick Perry said, "everyone has been accounted for and there is no initial indication of any worker exposure or an airborne radiological release." But Edwin Lyman of the Union of Concerned Scientists emphasized that "collapse of the earth covering the tunnels could lead to a considerable radiological release….this a potentially serious event.”

Robert Alvarez, a former DOE official, told the Post in an email that “the tunnels now store contaminated train cars and a considerable amount of highly radioactive, ignitable wastes including possible organic vapors.” Inspection of the tunnels has not been possible, he said, because radiation levels are too high.

We may never know the full extent of the damage from this latest incident at Hanford, which has been plagued by serious problems for years. Many critical nuclear industry oversight positions remain unfilled by the Trump Administration.

The 580-square-mile Hanford facility dates back to the 1940s production of the first atomic bombs, and is the nation’s major repository for high-level radioactive wastes from seven decades of nuclear weapons production. Since 1989, the Department of Energy has spent billions cleaning up nine reactors and other radioactive facilities there. One commercial reactor, the Columbia Generating Station, still operates at Hanford.

The tunnel collapse happens at a time when the nuclear power industry appears to be in an accelerating death spiral.

Two reactors under construction at Vogtle, Georgia, may be on the brink of cancellation. Some $13 billion in cost overruns sparked a Westinghouse bankruptcy, and primary owner Southern Company is looking for billions more to finish a project already years behind schedule and billions over budget. Huge rate increases within Georgia have seriously poisoned the climate for more state money.

Southern representatives recently asked the White House for help, (and termed the response “A-Plus”). But Vogtle was begun with some $8.35 billion in guaranteed federal loans from Barack Obama. Whether the feds will shell out another $4.3 billion is another story, as is the question of whether that would actually be enough to do the job, and how long it would really take.

In neighboring South Carolina, SCANA Corp. may pull the plug on its massive double-reactor V.C. Summer project, which is also billions over budget and a contributor to the Westinghouse bankruptcy. Should both Summer and Vogtle go down, there will be zero new reactors under construction in the U.S. for the first time since the 1950s. It would mark the definitive end of the “Peaceful Atom” as a source of future new large-scale power capacity in the United States.

Some atomic devotees are pushing small-scale “modular” reactors as a possible future energy source. But they're untested, underfinanced, uncompetitive and unlikely to come to fruition.

Ninety-nine reactors remain licensed to operate in the United States. They average well over thirty years of age. Most cannot compete with fracked gas or renewables, and would close rapidly in a free-market situation. Last year New York Governor Andrew Cuomo intervened to save four upstate reactors with $7.6 billion in subsidized rates. A similar bailout is underway in Illinois.

Are we seeing the definitive end of the “Peaceful Atom” as a source of future new large-scale power capacity in the United States?

Throughout the United States, reactor owners are now flooding state legislatures with bailout scams. In Ohio, FirstEnergy's pleadings for $4.5 billion for Davis-Besse near Toledo and Perry near Cleveland are meeting stiff resistance. How long the nation’s operable reactors stay open will depend entirely on how much money their owners can gouge out of the public.

Meanwhile the Hanford tunnel collapse further challenges the industry's credibility on dealing with radioactive waste. Three years ago America’s only major operable waste storage facility, at Carlsbad, New Mexico, exploded due to the use of inappropriate kitty litter (truly!). Some twenty-one workers were exposed and the facility was shut for three years. Fierce debate has eruptedover the disposal of wastes left behind by the shutdown of California’s San Onofre reactors, between Los Angeles and San Diego, with billions of dollars at stake. Other such fights are sure to escalate as more reactors close.

Industry advocates claim much of this could be solved by opening a national waste dump at Yucca Mountain, Nevada, a project nixed by the Obama Administration. The Trump budget proposes some $120 million to start a Yucca revival process. But $12 billion has already been spent on what amounts to a tunnel through a dormant volcano in the middle of the desert. Estimates to finish Yucca run to $96 billion and beyond. Finish times stretch to a decade or more.

Nuclear energy faces a seriously clouded future.
