MOSCOW/WASHINGTON - Reuters - Fri Jul 2, 2010 4:15pm EDT 
His face wracked by age and his voice  rasping after decades of chain-smoking coarse tobacco, the former  long-time Russian Minister of nuclear energy and veteran Soviet  physicist Viktor Mikhailov knows just how to fix BP's oil leak in the  Gulf of Mexico. 
"A nuclear explosion over the leak," he says nonchalantly puffing a  cigarette as he sits in a conference room at the Institute of Strategic  Stability, where he is a director. "I don't know what BP is waiting for,  they are wasting their time. Only about 10 kilotons of nuclear  explosion capacity and the problem is solved." 
A nuclear fix to the leaking well has been touted online and in the  occasional newspaper op-ed for weeks now. Washington has repeatedly  dismissed the idea and BP execs say they are not considering an  explosion -- nuclear or otherwise. But as a series of efforts to plug  the 60,000 barrels of oil a day gushing from the sea floor have failed,  talk of an extreme solution refuses to die. 
For some, blasting the problem seems the most logical answer in the  world. Mikhailov has had a distinguished career in the nuclear field,  helping to close a Soviet Union program that used nuclear explosions to  seal gas leaks. Ordinarily he's an opponent of nuclear blasts, but he  says an underwater explosion in the Gulf of Mexico would not be harmful  and could cost no more than $10 million. That compares with the $2.35  billion BP has paid out in cleanup and compensation costs so far. "This  option is worth the money," he says. 
And it's not just Soviet boffins. Milo Nordyke, one of the masterminds  behind U.S. research into peaceful nuclear energy in the 1960s and '70s  says a nuclear explosion is a logical last-resort solution for BP and  the government. Matthew Simmons, a former energy adviser to U.S.  President George W. Bush and the founder of energy investment-banking  firm Simmons & Company International, is another calling for the  nuclear option. 
Even former U.S. President Bill Clinton has voiced support for the idea  of an explosion to stem the flow of oil, albeit one using conventional  materials rather than nukes. "Unless we send the Navy down deep to blow  up the well and cover the leak with piles and piles and piles of rock  and debris, which may become necessary ... unless we are going to do  that, we are dependent on the technical expertise of these people from  BP," Clinton told the Fortune/Time/CNN Global Forum in South Africa on  June 29. 
Clinton was picking up on an idea mooted by Christopher Brownfield in  June. Brownfield is a one-time nuclear submarine officer, a veteran of  the Iraq war (he volunteered in 2006) and now a nuclear policy  researcher at Columbia University. He is also one of a number of  scientists whose theories rely not on nuclear bombs -- he did toy with  that thought for a while -- but on conventional explosives that would  implode the well and, if not completely plug it with crushed rock, at  least bring the flow of oil under control. "It's kind of like stepping  on a garden hose to kink it," Brownfield says. "You may not cut off the  flow entirely but it would greatly reduce the flow." 
BLASTS FROM THE PAST 
Using nuclear blasts for peaceful ends was a key plank of Cold War  policy in both the United States and the Soviet Union. In the middle of  last century, both countries were motivated by a desire to soften the  image of the era's weapon of choice. 
Washington had big plans to use peaceful nuclear explosions to build an  additional Panama Canal, carve a path for an inter-state highway through  mountains in the Mojave Desert and connect underwater aquifers in  Arizona. But the experimental plans were dropped as authorities learned  more about the ecological dangers of surface explosions. 
The Soviet program, known as Nuclear Explosions for the National  Economy, was launched in 1958. The project saw 124 nuclear explosions  for such tasks as digging canals and reservoirs, creating underground  storage caverns for natural gas and toxic waste, exploiting oil and gas  deposits and sealing gas leaks. It was finally mothballed by Mikhail  Gorbachev in 1989. 
The Soviets first used a nuclear blast to seal a gas leak in 1966.  Urtabulak, one of its prized gas-fields in Uzbekistan, had caught fire  and raged for three years. Desperate to save the cherished reserves,  Yefim Slavsky, then Minister of Light Industry, ordered nuclear  engineers to use the most powerful weapon in their arsenal. 
"The Minister said, 'Do it. Put it out. Explode it,'" recalls Albert  Vasilyev, a young engineer and a rising star in the project who now  teaches at the Lenin Technical Institute in Moscow. 
Vasilyev remembers the technology behind the program with obvious pride.  "The explosion takes place deep underground," he says. "We pinch the  pipe, break it and the pipe collapses." According to Vasilyev, the blast  at Urtabulak sealed the well shut leaving only an empty crater. 
JUST DOING A JOB 
In all, the Soviets detonated five nuclear devices to seal off runaway  gas wells -- succeeding three or four times, depending on who you talk  to. "It worked quite well for them," says Nordyke, who authored a  detailed account of Soviet explosions in a 2000 paper. "There is no  reason to think it wouldn't be fine (for the United States)." 
But not everything went smoothly. Vasilyev admits the program "had two  misfires". The final blast in 1979 was conducted near the Ukrainian city  of Kharkov. "The closest houses were just about 400 meters away,"  Vasilyev recalls. "So this was ordered to be the weakest of the  explosions. Even the buildings and the street lamps survived."  Unfortunately, the low capacity of the device failed to seal the well  and the gas resurfaced. 
Alexander Koldobsky, a fellow nuclear physicist from the Moscow  Engineering and Physics Institute, insists the peaceful nuclear  explosions were safe. The people who worked on the program "were  brilliant professionals", he says. "They had a culture of safety, which  did not accept the word 'maybe', but only accepted the words  'obligation' and 'instruction.' Any derivation from these in nuclear  technologies is a crime." 
Still, he concedes, "there were different scenarios of what happened  after an explosion." At his first blast in a Turkmen gas field in 1972,  "the stench was unbearable," he says. "And the wind was blowing toward a  nearby town." He closes his narrow lips into a smile as if refusing to  say more. 
Koldobsky shrugs off any suggestion of fear or emotion when the bomb  exploded. "I felt nothing. I was just doing my job." 
Not everybody is so sanguine about the Soviet experience. Speaking on  condition of anonymity, an expert from Russia's largest oil exporter  Rosneft (ROSN.MM), urges the United States to ignore calls for the  atomic option. "That would bring Chernobyl to America," he says. 
Vladimir Chuprov from Greenpeace's Moscow office is even more insistent  that BP not heed the advice of the veteran Soviet physicists. Chuprov  disputes the veterans' accounts of the peaceful explosions and says  several of the gas leaks reappeared later. "What was praised as a  success and a breakthrough by the Soviet Union is in essence a lie," he  says. "I would recommend that the international community not listen to  the Russians. Especially those of them that offer crazy ideas. Russians  are keen on offering things, especially insane things." 
Former Minister Mikhailov agrees that the USSR had to give up its  programme because of problems it presented. "I ended the program because  I knew how worthless this all was," he says with a sigh. "Radioactive  material was still seeping through cracks in the ground and spreading  into the air. It wasn't worth it." 
"Still," he says, momentarily hard to see through a cloud of smoke from  his cigarettes, "I see no other solution for sealing leaks like the one  in the Gulf of Mexico." 
The problem, he goes on, is that "Americans just don't know enough about  nuclear explosions to solve this problem ... But they should ask us --  we have institutes, we have professionals who can help them solve this.  Otherwise BP are just torturing the people and themselves." 
RADIATION RISKS 
Nordyke too believes the nuclear option should be on the table. After  seeing nine U.S. nuclear explosions and standing behind the control  board of one, he estimates that a nuclear bomb would have roughly an 80  to 90 percent chance of successfully blocking the oil. According to his  estimates, it would have to be an explosion of around 30 kilotons,  equivalent to roughly two Hiroshima bombs or three times as big as  Mikhailov's estimate. The explosion would also need to remain at least 3  to 4 miles away from other offshore wells in the area. 
The bomb, says Nordyke, would be dropped in a secondary well  approximately 60-70 feet away from the leaking shaft. There it would  create a large cavity filled with gas. The gas would melt the  surrounding rock, crush it and press it into the leaking well to close  it shut. 
Although the BP well is thousands of feet deeper than those closed in  the Soviet Union, Nordyke says the extra depth shouldn't make a  difference. He also says that so far below the ground, not much  difference exists in onshore or underwater explosions -- even though the  latter have never been tried. 
Nordyke says fears that radiation could escape after the explosion are  unfounded. The hole would be about 8 inches in diameter and, despite the  shockwave, the radiation should remain captured. Even in the case of  radiation escape, he says, its dispersed effect would be less than that  of floating oil patches. 
A LAST RESORT 
But don't expect an explosion under the Gulf of Mexico any time soon.  Even a conventional blast could backfire and cause more problems. There  is a chance any blast could fracture the seabed and cause an underground  blowout, according to Andy Radford, petroleum engineer and American  Petroleum Institute senior policy adviser on offshore issues. The U.S.  Department of Energy has no plans to use explosives "due to the obvious  risks involved," according to a DOE spokeswoman. 
There's also the question of time. Preparations for a nuclear explosion  could take up to half-a-year; BP has said it will have a relief well in  place to stop the leak by August. "I think it has to be considered as  only the last resort," Nordyke says. But "they ought to be thinking  about it." 
Would he be willing to work on such an operation? "I'd be happy to  help," he says.
