Soviet Nuclear Test Site Now A Model For Safeguards by Mike Shuster

Nobuhiro Muroya, the IAEA's senior official here, remarked on the irony of the region's history Thursday after the final seal was put in place.
"It is a coincidence that in this nuclear test site, it was more than 450 nuclear weapons tested. But this site is at the same time now very safe and very peaceful. And we would like this material to stay calm and peacefully for a long time," he said.
That is the intention of the U.S. and Kazakhstan governments. The storage casks are designed to last half a century.

US says another NKorean nuclear test would be provocative

Another atomic weapons test by North Korea would be provocative, a State Department spokesman said, adding he could not confirm reports that Pyongyang was preparing for such a test. "I'm aware of the reports. They obviously go into intelligence matters so I can't really go into any detail commenting on them," spokesman Mark Toner said when asked to comment on a report in South Korea's newspaper Chosun Ilbo.
"But this hasn't changed our position vis-a-vis North Korea. We said all along that they need to adhere to their commitments and they also need to refrain from provocative actions," Toner said.
"Another nuclear test would certainly fall into the rubric of provocative actions," he added.
He said "no" when asked whether he had evidence to support the details of the news report.
According to Chosun Ilbo, South Korea's biggest-selling newspaper, US satellites detected movements of personnel and vehicles at the site where the the North carried out its first two nuclear tests in 2006 and 2009.
Chosun quoted an unidentified government source as also saying that the North also appears to be restoring tunnels demolished during the first two tests.
"However, it is unlikely (the North will) carry it out soon. It is expected to take another three months (to complete preparations for a third test)," the source said.
But a spokesman for South Korea's Joint Chiefs of Staff said there was no evidence of any such preparations.

North Korea Reported to be Readying New Nuke Test


A U.S. satellite has reportedly spotted heightened operations at a nuclear weapons test location in North Korea, possibly indicating the Stalinist state is readying for a third nuclear test blast, Reuters reported today (see GSN, Oct. 20).
North Korean soldiers stand guard yesterday at Panmunjom, near the Demilitarized Zone dividing the Koreas. Increased activity at a site in North Korea suggests Pyongyang could be preparing to conduct a third nuclear test, a South Korean official said (Park Ji-hwan/Getty Images).
The South Korean Chosun Ilbo newspaper cited a government official in Seoul as the source of its information. The report follows satellite photographs from last month that point to renewed construction or excavation activities at the site of a destroyed cooling tower in the North's plutonium-producing Yongbyon nuclear installation.
Fully aware it is monitored by satellites, Pyongyang could be simply shifting equipment around in a ruse to suggest test preparations. The United States last spring rejected reports that the North was preparing to detonate a third test device.
North Korea carried out nuclear tests in 2006 and 2009. Those tests were used by autocratic ruler Kim Jong Il to increase his standing domestically and to build support for his military-first policy.
Another test would bolster the Stalinist state's capacity to build strategic arms while also reducing its quantity of weapon-ready material. The North is believed to have fissile material stores adequate for building six to eight weapons (Jeremy Laurence, Reuters, Oct. 20).
The anonymous government source told Chosun that "hectic movements of personnel and vehicles have recently been detected in Punggyeri," Agence France-Presse reported.
North Korea also seemed to be repairing tunnels destroyed by the previous two nuclear tests, the source said.
"However, it is unlikely (the North will) carry it out soon. It is expected to take another three months (to complete preparations for a third test)," the source said.
A South Korean Joint Chiefs of Staff spokesman, though, said there were no sure signs of groundwork for another nuclear test.
"We have no concrete evidence to support the news report," the spokesman said. "We're watching closely any development concerning the North's nuclear facilities and sharing information with countries concerned."

An unidentified South Korean Defense Ministry official indicated activities like those reported by newspaper were fairly standard, potentially for the regular upkeep of important strategic installations. More at:

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).
