Alleged North Korean Reactor Flouts U.N., South Says


If North Korea is indeed constructing a light-water nuclear reactor, it would be in contravention to U.N. Security Council resolutions prohibiting the aspiring nuclear power from any nuclear work, South Korea's top diplomat said yesterday (see GSN, Nov. 15).
South Korean Foreign Minister Kim Sung-hwan said to journalists,"that would be running counter to U.N. resolutions and it is obvious that it wouldn't be conducive to the current situation," the Yonhap News Agency reported.
Siegfried Hecker, a former head of the Los Alamos National Laboratory in New Mexico, this week said the North was building the experimental reactor at its Yongbyon nuclear complex. Hecker was returning from a trip to the isolated state when he made the remarks.
Kim said additional time is required to probe Hecker's report as the Stalinist state has no background in constructing light-water reactors.
He also disputed Pyongyang's repeated assertion that it has the right to develop civilian atomic power, saying the North gave up that right when it withdrew from the Nuclear Nonproliferation Treaty in 2003 (Yonhap News Agency I, Nov. 15).
Responding to the light-water reactor report, the U.S. State Department yesterday again called on Pyongyang to demonstrate its commitment to denuclearization, Yonhap reported.
"We expect North Korea to live up to its international obligations," State Department spokesman P.J. Crowley said. "As it does, we are prepared to have conversations with North Korea about its long-term requirements. But first and foremost, North Korea has to live up to its stated commitment" (Hwang Doo-hyong, Yonhap News Agency II, Nov. 15).
The Obama administration has refused calls to return to the stalled six-nation talks -- which also involve China, Japan, the two Koreas, and Russia -- until Pyongyang shows it is sincere about nuclear disarmament. Washington fears a repeat performance from the North whereby Pyongyang takes some limited steps toward denuclearization only to reverse course once it has extracted some international concessions.
North Korea pulled out of nuclear negotiations in April 2009 and one month later detonated its second nuclear test device. That action earned it heightened U.N. Security Council sanctions that are thought to have left the already impoverished nation badly weakened.
Meanwhile, North Korea's state-controlled media yesterday announced former U.S. State Department official Morton Abramowitz had traveled to Pyongyang with a retinue of U.S. experts on North Korea. No further information was provided, Yonhap reported (Yonhap News Agency III, Nov. 15).

Energy Chief Calls For Review of Nuclear Projects from GSN Daily News

U.S. Energy Secretary Steven Chu has ordered an independent assessment of plans for a new plutonium research facility at the Los Alamos National Laboratory in New Mexico and a new uranium processing plant in Tennessee, the Albuquerque Journal reported yesterday (see GSN, Aug. 27).
Chu has directed the formation of a panel of specialists with "no stake in the outcome" to analyze the necessity for the Chemistry and Metallurgy Research Replacement complex at Los Alamos and the Uranium Processing Facility at the Y-12 National Security Complex in Tennessee, a department release said (see GSN, July 27).
The Chemistry and Metallurgy Research Replacement complex is planned to take the place of a World War II-era plutonium laboratory. Officials have maintained that the plutonium site's work is critical to fulfilling Los Alamos's nuclear weapons mission. The project is now estimated to cost no less than $4 billion -- a figure significantly greater than earlier estimates. Design activities have yet to conclude and the project has missed its original schedule by years.
Likewise, cost estimates for the Y-12 highly enriched uranium processing center have seriously overshot earlier informal estimates of between $1.4 billion and $3.5 billion. News reports indicate the site could cost up to $5 billion to build.
Developing the two facilities is key to the Obama administration's pursuit of Senate ratification of a new U.S.-Russian nuclear arms control pact, the Journal reported. A number of Republican senators have said their potential support for the treaty would depend upon sufficient funding for modernizing the nation's nuclear-weapon complex (see related GSN story, today).
The National Nuclear Security Administration, a semiautonomous arms of the Energy Department, has oversight over the two projects. The Energy and Defense departments have already initiated separate analyses of the facilities' funding requirements (John Fleck, Albuquerque Journal, Oct. 28).

New Kind of Uranium Could Power Your Car Nuclear power may go portable with this new form of uranium.

Study: New uranium compound holds nuclear, petroleum breakthroughs
A form of uranium discovered by scientists from the Los Alamos National Laboratory may be utilized as a safer and less expensive nuclear fuel. The new molecule also draws a greater amount of energy from fossil fuels. "Actinide nitrides are candidate nuclear fuels of the future. But they can also break carbon-hydrogen bonds, which are very strong," said Jaqueline Kiplinger, one of the scientists involved in the study. Discover

U.S. Detonates Explosives in Plutonium Study from GSN Daily News

Comprehensive Nuclear-Test-Ban TreatyImage via Wikipedia
The United States on Wednesday conducted an underground non-nuclear test detonation in Nevada to study the behavior of plutonium, the Associated Press reported (see GSN, Aug. 13).
The event, code-named "Bacchus," was the 24th subcritical test conducted since 1997 at what is now called the Nevada National Security Site. It was first such experiment since the "Unicorn" detonation on Aug. 30, 2006, at the installation, previously known as the Nevada Test Site, the National Nuclear Security Administration indicated (see GSN, Aug. 24).
Subcritical tests, which do not involve fission chain reactions that produce nuclear explosions, are key to ensuring the dependability of the U.S. nuclear deterrent, according to U.S. officials.
In the latest study, Los Alamos National Laboratory researchers detonated conventional explosives surrounding a cache of radioactive material in a uniquely built sphere, NNSA spokesman Darwin Morgan said. The test, conducted in a vault roughly 1,000 feet below the earth's surface, produced no nuclear reaction and emitted no radioactivity, he said.
Opponents of subcritical tests contend the experiments go against the purpose of the Comprehensive Nuclear Test Ban Treaty, a pact Washington has yet to ratify (see GSN, July 27; Ken Ritter, Associated Press/Reno Gazette-Journal, Sept. 16).
