Six-nation talks to defuse the nuclear crisis on the Korean Peninsula are scheduled to begin Aug. 25 and to last three days, the Sydney Morning Herald reported today (see GSN, Aug. 8).
The talks will also involve more senior officials than those who took part in an inconclusive April meeting, according to Chinese Vice Foreign Minister Wang Yi. The talks are not expected to produce an immediate solution to the crisis, the Morning Herald reported.
The negotiations are “just a beginning,” according to Chinese President Hu Jintao (Hamish McDonald, Sydney Morning Herald, Aug. 11).
Meanwhile, Russia will hold talks with North and South Korea in Moscow this week, according to Russian Deputy Foreign Minister Alexander Losyukov.
“The consultations will begin literally the day after tomorrow,” Losyukov said yesterday. “We are working on the possibility of conducting a similar meeting with Japan in the near future,” he added (Reuters/Pakistan Business Recorder, Aug. 11).
Another senior Russian official dismissed reports that North Korea agreed to multilateral talks only after receiving assurances they would be allowed to meet with U.S. diplomats directly.
“The North Korean side has put forward no conditions, and to my understanding Pyongyang is interested exactly in six-way talks,” said Deputy Foreign Minister Yuri Fedotov (Reuters/Planet Ark, Aug. 8).

WASHINGTON — An explosion caused by low-yield nuclear “bunker-busting” devices meant to destroy deeply buried chemical and biological weapons would probably not sterilize those agents, but rather would disperse them into the surrounding environment, a Council on Foreign Relations expert said recently (see GSN, Aug. 8).
According to Robert Nelson, senior fellow in science and technology at the council, a nuclear weapon used to attack an underground storage facility would not emit enough heat to properly destroy all the chemical or biological agents that may be stored there. Because low-yield nuclear weapons would probably need to bore through several feet of solid rock to reach their target, the surrounding earth would simply absorb much of the heat from the nuclear explosion.
The U.S. understanding of the heat produced by nuclear explosions was developed during Cold War-era atmospheric nuclear tests, Nelson said, and many low-yield weapon development advocates may be under a false impression that an underground explosion would produce the amount of heat necessary to disarm the hazardous weapons.
This year, the Bush administration has asked Congress to lift a 1994 ban to allow the research and development of low-yield nuclear weapons, those with yields below five kilotons.
“The scenarios for bunker busting [and] agent defeat that proponents use to justify new weapons are either ineffective, or only marginally more effective, than conventional alternatives,” said Nelson, who has written a paper on the topic that will be published in the journal Science & Global Security. “Using a nuclear weapon to destroy CBW [chemical and biological weapons], for example, is more likely to disperse active agent into the environment,” he added.
The U.S. military’s precision-guided weaponry won’t help either, Nelson claimed. Even the most technologically advanced missiles would still have to hit any chemical and biological weapon cache head-on, with little room for error.
According to Nelson, even if a bunker buster missed its target by only a few feet, there would be a strong possibility that the targeted agents could be released. The chances for success are decreased even further, Nelson said, when one further considers the uncertainty of military intelligence and the possibility of an enemy routinely shifting the location of its underground stockpiles.
In addition, Nelson noted, the fallout from a low-yield explosion could produce devastating effects and could contaminate civilians and members of the U.S. military in the theater with radiation or dispersed WMD agents.
“Everyone seems to agree that earth-penetrating weapons would produce a lot of fallout,” he said. “I was surprised at the agent-defeat scenario. My intuition was wrong like everyone else: I assumed the heat would sterilize the germs. But our intuition based on air explosions like the Hiroshima weapon is just wrong when you detonate below ground, where the density of dirt is 2,000 times higher than air.
“There just isn’t enough heat available to sterilize more than a few percent of the material ejected from the crater,” Nelson added.
Nelson said the best way to ensure that chemical and biological agents are properly secured is to seal off the site and sterilize the weapons using conventional means.
“If they are buried underground, the best thing to do is to leave [them] there” until military crews can safely disarm them, he said.
Nelson released his findings during a recent press conference to launch the new book Tactical Nuclear Weapons: Emergent Threats in an Evolving Security Environment, to which he contributed a chapter that focused on the low-yield nuclear issue. Nelson said officials from the National Nuclear Security Administration are aware of his pending paper, but they plan to conduct their own study.
Resumed Testing Could Answer Questions
Heritage Foundation Fellow Baker Spring said Nelson’s assertions may very well prove true, and the United States could only learn for certain if it resumed nuclear testing.
Nelson said he isn’t opposed to “conceptual” work inside laboratories, but he opposes a U.S. return to explosive testing or the deployment of new weapons.
“By returning to new weapon development and/or testing, the United States would signal that it is still interested in finding new uses for nuclear weapons — especially low-yield tactical or battlefield weapons to be used in Third World conflicts,” he said, noting that various countries may decide to counter the perceived threat from the United States by building and testing their own weapons.
“Russia and China would likely test if the U.S. tests,” Nelson said. “Russia is also more dependent now on its nuclear forces given that NATO has such conventional superiority. A renewed U.S. program would give ammunition in Russia and China to their nuclear proponents who wish to develop new weapons of their own,” he said.
Spring, however, said he suspects Nelson’s research is a political work disguised as a scientific study.
Nelson’s technical argument “asserts the ineffectiveness of the weapon prior to testing it,” Spring said. “Dr. Nelson may well be right. He believes strongly in his position, so he should have no fear of being proven wrong by the testing program. Indeed, I suspect he does not fear being proven wrong. I suspect what he fears is that the testing program itself has policy implications he dislikes,” he added.
“Though I have a different view in this case, there is nothing wrong with Dr. Nelson arguing for a particular policy. What is wrong is to hide policy arguments behind technological arguments and use the supposedly unassailable technological arguments to imply that all informed and reasonable people must agree to support the same policy position,” Spring said. Unless direct and compelling policy arguments against undertaking development and testing of this class of weapons are made, it is my view that the program should go forward.”
The Japanese taboo of discussing the development of nuclear weapons is disappearing, the Associated Press reported Saturday (see GSN, Feb. 20).
“People are clearly waking up to the idea,” said opposition lawmaker Shingo Nishimura, who was forced to step down in 1999 as vice minister for defense after he suggested that Japan should consider acquiring nuclear weapons.
Senior ruling party officials Yasuo Fukuda and Shintaro Abe have suggested this year that Tokyo consider the nuclear option, AP reported.
“Japan must start saying right now that it might go nuclear,” said Tadae Takubo, a professor of policy at Kyorin University. “For a nation to entirely forsake nuclear weapons is like taking part in a boxing match and promising not to throw hooks,” Takubo added.
While the discussion of nuclear weapons is becoming more acceptable, Prime Minister Junichiro Koizumi said Japan will not seek a nuclear capability.
“Our country’s stance on this will not change,” he said. “We will do our utmost to advance the call for smaller nuclear arsenals and nuclear nonproliferation while working toward ridding the world of nuclear weapons,” Koizumi added (Yuri Kageyama, Associated Press/Boston Globe, Aug. 9).
Russian Deputy Defense Minister Col. Gen. Alexei Moskovsky has said Russia plans to begin testing the new Bulava sea-launched ballistic missile next year, Jane’s Defense Weekly reported today (see GSN, Aug. 7).
Russia is set to begin testing the Bulava SLBM in 2004 on a Typhoon-class submarine, Moskovsky said. The missile is then set to be installed on three Borey-class submarines, which are scheduled to be operational by 2010, he said.
Each Borey-class submarine will be armed with 12 Bulavas, Russian defense industry sources said. Each Bulava, designed to have a range of more than 8,300 kilometers, is expected to be equipped with multiple warheads, according to Jane’s.
The Borey-class submarine has a displacement of 17,000 tons, measures 170 meters in length and has a crew of 130, Jane’s reported. The submarine is equipped with both a nuclear reactor for high speeds and a low-noise electric engine. The submarine is also equipped with the latest in underwater noise reduction measures, project officials said (Nikolai Novichkov, Jane’s Defense Weekly, Aug. 13).

WASHINGTON — Congressional auditors have found budgeting, cost accounting and management problems associated with a U.S. National Nuclear Security Administration program to extend the operational life of U.S. nuclear weapons, according to a U.S. General Accounting Office report released Friday (see GSN, Aug. 5).
In 1996, the U.S. Energy Department created the Stockpile Life Extension Program, which is now conducted by the NNSA’s Office of Defense Programs. The purpose of the program is to use a standardized approach to refurbish nuclear weapons to extend their operational life.
As of May, three types of nuclear weapons were undergoing research activities in advance of their refurbishment — the W-80 warhead, the B-61 bomb and the W-76 warhead, according to the report. The W-80 is intended for use on a cruise missile launched from an attack submarine or B-52 bomber and is scheduled to begin refurbishment in February 2006. The B-61 bomb is designed to be carried on the B-52 and B-2 bombers and is expected to begin refurbishment in June 2006. The W-76 warhead is designed to be used on the Trident 2 submarine-launched ballistic missile and is scheduled to begin refurbishment in September 2007.
In its report, the GAO said there are opportunities to improve the budgeting, accounting and management of the stockpile extension program. The report also says that NNSA officials agreed with the need to improve the management of the program.
The GAO found the NNSA budget for the stockpile extension program to be neither comprehensive nor reliable, the report says. For example, the NNSA fiscal 2003 budget for the program was developed by broad function, such as research and development activities, instead of by an individual weapon system or program, such as the stockpile extension program, it says.
The report did find, however, that the NNSA has begun to create a more comprehensive picture of the stockpile extension program for fiscal 2004. In its fiscal 2004 budget, the NNSA attributed a larger portion, but not all, of life-extension work to the stockpile extension program, the report says. It recommends that the NNSA further improve budgeting procedures associated with the stockpile extension program by including it as a formal section in the overall NNSA budget submission.
The NNSA also lacks a system for tracking refurbishment costs, according to the report. It says that the NNSA has yet to create a cost accounting system that provides full costs of refurbishment activities. Instead, the NNSA has several systems to track various portions of refurbishment costs, but these are used for various purposes and cannot be reconciled with each other, the report says, adding that the NNSA administrator should improve cost accounting procedures associated with the stockpile extension program.
In addition, there are other management concerns related to the planning, organization and oversight of cost and schedule factors for the stockpile extension program, the report says. For example, the NSSA has yet to prioritize the stockpile extension program among other Office of Defense Program activities or to prioritize the various refurbishment activities, it says. The report also says that the NNSA lacks an adequate process to report cost and schedule changes against established baselines. The GAO has recommended that the NNSA begin improving specific management-related activities associated with the program.
Kyrgyzstan has ratified the Comprehensive Test Ban Treaty, the Russian Foreign Ministry announced last week (see GSN, July 23).
In a statement released Aug. 6, the ministry praised Kyrgyzstan’s decision to ratify the CTBT, saying the move was “another step toward ensuring the universal nature of this treaty, which is one of the important tasks facing the international community now” (Russian Foreign Ministry release, Aug. 6).
When Kyrgyzstan submits its ratification to the United Nations, it will become the 105th party to the treaty. Kyrgyzstan is not one of the 44 nations that must ratify the treaty before it can enter into force. Of those 44 nations, 32 have ratified the treaty (CTBT Organization).
