New laser technology stirs nuclear bomb proliferation fears

 

A new way of making nuclear fuel with lasers may help cut costs and ensure energy security but could also make it easier for rogue states to secretly build nuclear weapons if they got hold of the know-how.

A debate about the benefits and dangers of using lasers instead of centrifuges to enrich uranium underlines the sensitivities surrounding nuclear activity that can have both civilian and military applications.

Uranium can provide the explosive core of a nuclear warhead if refined to a high fissile concentration, explaining why any country or other actor interested in obtaining nuclear arms might be eager to learn about technical advances in enrichment.

The U.S. Nuclear Regulatory Commission (NRC) last month issued a license to a partnership between General Electric Co. and Japan's Hitachi Ltd to build and run a laser enrichment plant for manufacturing reactor fuel.

It would be the world's first facility to refine uranium on a commercial scale using lasers, a technique "particularly suited for nuclear proliferation", said Assistant Professor R. Scott Kemp of the Massachusetts Institute of Technology (MIT).

"It appears that they have allowed the license to go forward without a serious review of the proliferation implications," said Daryl Kimball, executive director of the Arms Control Association, a Washington-based advocacy and research group.

Pentagon Cries Poor, Starts $10 Billion Nuclear Weapon Upgrade ....

 

The Pentagon is facing its worst cash crunch in more than a decade, with potential cuts of up to a half-trillion dollars over the next decade if Congress doesn’t act soon.

Yet the U.S. military still somehow found the money on Tuesday to put a down payment on a $10 billion upgrade of its nuclear weapons in Europe — y’know, just in case there’s another Cold War.

Un esperimento chiamato "Pollux" ....

Less than Critical ....

 

The United States last week conducted a subcritical nuclear experiment to collect data to help the nation maintain a safe and reliable nuclear weapons stockpile, announced the National Nuclear Security Administration, an agency of the Energy Department.

 

http://www.nnsa.energy.gov/mediaroom/pressreleases/pollux120612

 

Dubbed Pollux, the plutonium-based experiment took place on Dec. 5 at the Nevada National Security Site in southern Nevada, northwest of Las Vegas, according to NNSA.

 

"Challenging subcritical experiments maintain our capabilities to ensure that we can support a safe, secure, and effective stockpile without having to conduct underground testing," said NNSA Administrator Thomas D'Agostino, in the agency's Dec. 6 release.

 

http://www.nnsa.energy.gov/aboutus/ourleadership/dagostinobiography

 

The United States last conducted an underground nuclear weapons test in September 1992.

A new diagnostic tool used in Pollux "resulted in more data collected in this single experiment" than in all other previous subcritical tests, said NNSA Deputy Administrator for Defense Programs Don Cook.

 

http://www.nnsa.energy.gov/aboutus/ourleadership/doncookbio

 

The data help ensure that "computer simulations can accurately predict performance," of the nuclear weapons, he noted.

 

Subcritical experiments produce no critical mass that would sustain a nuclear chain reaction; thus, there is no nuclear explosion, according to NNSA.

 

Pollux was the 27th subcritical experiment to date.

 

The previous one, Barolo B, took place in February 2011.

Air Force Eyes Studies on Future Nuclear Cruise Missile ....

 

 

The Air Force announced that it intends to award contracts to Boeing, Lockheed Martin, Northrop Grumman, and Raytheon for each company to study performance attributes of the next-generation nuclear cruise missile that the service intends to develop and field.

 

Each company is expected to receive a fixed-price contract for these trade studies, which will support the technology development phase of the Long Range Standoff, or LRSO, program, states the notice posted at the Federal Business opportunities website on Dec. 5.

 

https://www.fbo.gov/index?s=opportunity&mode=form&id=fcee8f7fb6b0fe17067051fcb0c200fc&tab=core&_cview=0

 

LRSO is envisioned as the successor to the Air Launched Cruise Missile that B-52s carry as an element of the US strategic nuclear deterrent.

 

In late March, senior service officials told Congress that the LRSO acquisition program would start in Fiscal 2015, two years later than originally planned, due to service-wide budgetary constraints.

 

http://www.airforce-magazine.com/DRArchive/Pages/2012/April%202012/April%2002%202012/CruiseMissile%27sStartSlips.aspx

 

However, the LRSO analysis of alternatives was still scheduled for completion early in this fiscal year, and there was no gap anticipated between LRSO and ALCM, which is expected to remain viable out to 2030 or beyond, they said.

Capisco che le bombe B61 siano state concepite con requisiti molto diversi dalle bombe convenzionali,però mi viene da pensare che è stato forse poco economico non impiegare i dispositivi di guida GPS già esistenti ed adattabili a più testate,come la Serie mark80, sulle testate nucleari tattiche aviotrasportate ed invece impiegare complicati e potenzialmente disturbabili sistemi a guida-radar

Non ricordo bene in quale Topic,ma nel Forum è stata postata una immagine della bomba B61 con alcuni detagli, in cui si fa riferimento al sistema di guida che comprende , forse fra altri, la guida-radar.

Remediating a Broken Arrow Site ....

 

Texas environmental authorities recently signed off that the Air Force has successfully completed efforts to remove uranium and lead contaminants from the site of a Cold War-era B-47 bomber crash near Dyess AFB, Tex.

 

"The site cleanup was a proactive, precautionary measure taken to provide for any potential future use of the land," said Judy Overbey, restoration manager for Dyess' 7th Civil Engineering Squadron, in the base's Dec. 12 release.

 

"The amount of contaminants found in the soil at the site was extremely low in most places," she added.

 

Atomic Energy Commission and base responders removed the majority of contaminants quickly after the B-47, which was carrying one nuclear bomb, caught fire on takeoff and crashed on Nov. 4, 1958, according to the release.

 

There was no nuclear detonation, but conventional explosives within the device scattered lead and uranium elements, some of which were left until final restoration efforts began in 2010.

 

Texas' environmental agency issued a closure letter on Nov. 1, certifying the site's suitability for agriculture and residential use, states the release.

New START: Don't Salt Before Tasting:

 

The Obama Administration is likely to try circumventing Congress to cut the US nuclear arsenal below the levels stipulated by the New START agreement with Russia, said Sen. John Hoeven (R-N.D.) on Wednesday.

"There are a number of reasons to be concerned about the future of our strategic deterrent," stressed Hoeven, speaking at a congressional seminar in Washington, D.C.

AFA sponsored the Feb. 6 event, along with the National Defense Industrial Association and Reserve Officers Association.

President Obama is "purportedly reviewing proposals that could unilaterally reduce our strategic weapons by several hundred warheads" below the 1,550 warhead limit of New START, he noted.

The Administration also "appears poised to negotiate new arms control agreements" with Russia that would bypass the Constitutional requirement for Senate ratification of formal treaties, he added.

New START implementation will not be completed until February 2018 and its "strategic effects remain unclear, so there's no strategic case for making additional nuclear reductions," asserted Hoeven.

As a result, "The Obama Administration should not reengage Russia on nuclear issues while New START is being implemented," he concluded.

Land and Sea Exchange ....
The United States and Russia have agreed to exchange telemetric information this year on the launch of an ICBM or submarine-launched ballistic missile that each nation conducted in 2012, announced the State Department on Tuesday.
This exchange falls under the verification and confidence-building measures called for in the New START agreement that entered force in February 2011.
Under New START, the United States and Russia are reducing their respective strategic nuclear arsenals to no more than 1,550 deployed warheads, 700 deployed launchers, and 800 deployed/non-deployed launchers by February 2018.
US and Russian delegations decided upon the telemetric exchange during a meeting of the Bilateral Consultative Commission in Geneva, Switzerland, according to the State Department's Feb. 19 release.
The BCC is the forum in which the two parties discuss treaty implementation issues.

Le preoccupazioni del generale Finan .... 21loqwp.jpg

For Nuclear Security, Eyes On, Hands Off Doesn't Work ....

 

Federal personnel overseeing the nation's nuclear weapons complex must reassert the lines of authority over the contractor security forces protecting the nuclear facilities and clarify roles and responsibilities, said Brig. Gen. Sandra Finan, Air Force Nuclear Weapons Center commander.

"That has been a long-standing issue that we really need to straighten out in order to create that accountability and ownership of that security mission," Finan told the House Armed Services Committee's strategic forces panel on Feb. 28.

"We have to be very clear on who's responsible for what," she added.

Under the policy of "eyes on, hands off," National Nuclear Security Administration personnel were "not really to interact with the contractor in executing security duties," she said.

The policy was deficient and led to a security breach last year at a nuclear facility by a group of elderly nun protesters, said lawmakers at the hearing.

"Nuclear security is absolutely critical and it is inherently a federal responsibility, and that means the federal personnel have a responsibility and a duty to be a little bit more specific and, in fact, tell contractors exactly how to do nuclear security," said Finan.

Una strada lunga da percorrere ....

Long Way to Go ....

 

After reviewing President Obama's Fiscal 2014 budget request, Rep. Mike Rogers (R-Ala.), chairman of the House Armed Services Committee's strategic forces panel, thinks the nation still has a long way to go to uphold its nuclear force structure. S

peaking on Capitol Hill on April 24, Rogers expressed concern that "nuclear modernization is in grave danger" due to the slow pace in modernizing the nation's nuclear infrastructure.

He cited delays to the B-61 life-extension program and W-78 and W-88 thermonuclear warhead life extensions as examples.

Rogers said he thinks the nuclear review that the Obama Administration is expected to complete in the next few months is likely to recommend significant further reductions to US nuclear forces.

"I find this deeply concerning given the sorry state of nuclear modernizations commitments" thus far, he said.

What Rogers finds even more troubling are reports that the Administration may seek to avoid Congress and undertake those reductions outside of the formal treaty process.

"I intend to ensure that no further reductions to US nuclear forces, including the New START treaty reductions, will occur without . . . explicit affirmative authorization by Congress," he said.

Get on With It ....

 

The United States needs to extend the life of the B61 nuclear bomb because that weapon remains vital to supporting the US' extended deterrent and NATO's nuclear mission, said Maj. Gen. Garrett Harencak, the Air Force's assistant chief of staff for strategic deterrence and nuclear integration.

"The fact of the matter is we need that weapon," he said during a June 7 address on Capitol Hill sponsored by the AFA, the National Defense Industrial Association, and Reserve Officers Association.

The United States supports NATO's nuclear role with dual-capable aircraft—F-15Es and F-16s based in Europe—that can carry nuclear bombs in addition to conventional weapons.

"We've always been committed to the DCA mission in Europe, and we remain so," said Harencak.

Refreshing the B61 is one step to "make sure the weapons we [have] there and how we store them remain modern, safe, secure, and effective," he said.

Toglietemi tutto ma non le armi nucleari:

 

i membri del congresso chiedono a Obama di riconsiderare le cose:

 

 

 

 

Forty-three members of Congress have penned a letter to President Obama urging him to reconsider unilateral reductions to the nation's nuclear arsenal. "Although we understand your desire for a world without nuclear weapons, we believe that your proposal would make that goal less attainable and jeopardize America's security," states the letter, which comes in response to a speech Obama delivered in Berlinon June 19 announcing his intentions to reduce the number of deployed strategic nuclear weapons by up to one-third. The letter argues that a strong nuclear deterrent provides security not only for the US but also for its allies. “We face a world today in which nuclear threats to the United States are increasing and our conventional military capabilities face dramatic reductions. In this context, our nuclear deterrent is becoming more important,” states the letter. “A robust, reliable nuclear force consisting of strategic bombers, intercontinental ballistic missiles, and submarine-launched ballistic missiles places our rivals on notice that there is no advantage to be gained in seeking to match U.S. nuclear forces and reassures our allies who rely on our nuclear ‘umbrella.’”
