DOE Decides to Bury Its Waste
To be or not to be, that is the question! Is the waste to be buried or the waste to be burned?
The DOE announced yesterday its intention to go forward with its plan to bury 6 metric tons (MT) of weapons grade, non-pit, plutonium at its WIPP site, in Carlsbad, New Mexico. This will be weapons grade plutonium obtained from a variety of sources, some of which are foreign. DOE's announcement refers to the down-blending methodology to be used, which may include conversion of the plutonium metal to an oxide powder, mixing with non-fissile isotopes of plutonium-oxide, and combining with other contaminants as well. (Final Surplus Plutonium Disposition Supplemental Environmental Impact Statement (Final SPD Supplemental EIS) (DOE/EIS-0283-S2, April 2015))
The DOE notes that its down-blending procedure renders the weapons-grade plutonium "not readily usable" for nuclear weapons; i.e., not without first removing the contaminants and chemically reducing the plutonium-oxide back to metal; in my opinion, not a very daunting process. Nevertheless, the Administration asserts that DOE's plan will make a significant contribution to nuclear non-proliferation. Hmm!
DOE/NNSA Undersecretary for Nuclear Security Frank Klotz signed the decision on the plutonium plan Wednesday, saying WIPP has a “proven process” for storing this type of waste stream; viz., it already has received 5 metric tons of surplus plutonium from the Rocky Flats Plant in Colorado and the Hanford Site in Washington.
New Mexico Governor S. Martinez has been quoted in the press as saying that she would welcome this latest addition to WIPP's inventory; i.e., as soon as DOE agrees that WIPP, now closed for emergency repairs, can be reopened. No surprise there!
However, DOE does not refer to the fact that their latest scheme for dispositioning surplus plutonium does not accord with the agreement arrived at years ago with the Russians to permanently dispose of surplus plutonium by burning it in specially designed nuclear reactors. It seems that the present Administration has decided that it is simply too expensive now to go ahead with that program; but, no mention is made of what the Russians may do as a result.
Meanwhile, the question remains of how to dispose of an additional 7 MT of plutonium from nuclear weapons pits. If the Administration is successful with its present plan, then it may be encouraged to bury this next installment of surplus plutonium at WIPP.
For the future, and of great potential concern to the citizens of New Mexico, the next Administration will have to grapple again with the problem of the disposition of high-level waste from nuclear power plants. Perhaps DOE will push to bury this dangerous long-lived waste at WIPP too. If so, then perhaps New Mexico's two US Senators will manage to push back?
Concerning the Obama administration's work on the non-proliferation of nuclear weapons and/or the achievement of nuclear weapons security for the USA, here are excerpts from an article in today's NYT:
As Obama Hosts Nuclear Security Summit, the Focus Is on China
By MARK LANDLER
MARCH 31, 2016
WASHINGTON — President Obama gathered more than 50 world leaders here on Thursday to discuss one of his favorite topics: locking down nuclear weapons.
“The entire premise of American foreign policy as it relates to nuclear weapons for the last 70 years has been focused on preventing the proliferation of nuclear weapons,” Benjamin J. Rhodes, deputy national security advisor, said. “That has been the position of bipartisan administrations, of everybody who has occupied the Oval Office.”
However, domestic politics and regional concerns both seemed to crowd out any discussion of global efforts to secure nuclear materials.
The terrorist attack in Belgium last week also cast a shadow over the gathering, particularly after reports that fighters for the Islamic State were seeking to penetrate a nuclear facility to obtain material for a so-called radioactive dirty bomb.
While the Democratic front-runner, Hillary Clinton, supports Mr. Obama’s nonproliferation policies, she has evinced little of his fervor for a nuclear-free world.
But as the leaders arrived for a dinner at the White House past an honor guard lined up along the South Lawn, Mr. Obama could claim one achievement: An amendment to a treaty that stiffens standards for protecting nuclear materials was signed by 102 nations.
The original protection agreement dates to 1987, but it has long been considered weak. The amendment, proposed after the Sept. 11, 2001, attacks, specifies minimum requirements for physical protection of civilian nuclear stocks, and for securing them when they are transported.
As part of an effort to be more open about its nuclear inventory, the United States announced that its stockpile of highly enriched uranium declined 20 percent, to 585.6 metric tons in 2013 from 740.7 metric tons in 1996. The decline was modest, but it was the first time in 15 years that the government released these numbers.
A senior administration official, who declined to speak on the record ahead of the president’s announcement, said that the amendments to the physical protection agreement are “the closest thing we have to legally binding standards for nuclear security.”
So, concerning the non-proliferation of nuclear weapons, and/or the achievement of nuclear weapons security for the USA, it seems that very modest progress has been made, but that the underlying existential threat remains. In summary, it is fair to say, in the words of the Poet::
And thus the native hue of resolution
is sicklied over, with the pale cast of thought,
and enterprises of great pitch and moment,
with this regard their currents turn awry,
and lose the name of action.
