Washington,
DC, September 22, 2006 - The prospects of a
Comprehensive Nuclear Test Ban Treaty (CTBT) in the early 1990's
led China to accelerate its testing schedule and discuss differences
within the Russian government over testing, according to documents
obtained through the Freedom of Information Act and archival
research and posted on the Web today by the National Security
Archive at George Washington University. The documents illustrate
the efforts of the U.S. Intelligence Community to understand
developments at Russian and Chinese nuclear test sites--Novaya
Zemlya and Lop Nur--from 1990 to 2000.
Today's posting includes 33 documents--many originally
classified Top Secret--produced under the auspices of the Director
of Central Intelligence, the Central Intelligence Agency, and
the Defense Intelligence Agency. The records were obtained by
Archive Senior Fellow Jeffrey T. Richelson while conducting
research for his recently-published book, Spying
on the Bomb: American Nuclear Intelligence from Nazi Germany
to Iran and North Korea. (W.W. Norton).
The documents include assessments of the link between nuclear
and sub-critical tests and weapons modernization programs in
Russia and China--both strategic and tactical nuclear weapons
programs.
Of particular interest is the report of an outside review panel
appointed by Director of Central Intelligence George J. Tenet
after detection of a seismic event in the vicinity of Novaya
Zemlya on August 16, 1997. That detection, combined with satellite
reconnaissance showing unusual activity at the test site, led
to concerns within the Intelligence Community that Russia had
conducted a nuclear test despite its pledge to abide by the
terms of the CTBT.
Electronic
Briefing Book
U.S. Intelligence on Russian and Chinese
Nuclear Testing Activities, 1990-2000
By Jeffrey Richelson
On September 24, 1996 seventy-one nations, including the five
acknowledged nuclear powers - the United States, Russia, France,
the United Kingdom, and the People's Republic of China - signed
the Comprehensive Test Ban Treaty (CTBT). The signatories pledged
not to conduct any nuclear weapon or other nuclear test explosion
and to prohibit such explosion on their territory. In addition,
they agreed to refrain from "causing, encouraging, or in
any way participating in the carrying out of any nuclear weapon
test explosion or any other nuclear explosion." (Note
1) The treaty did not ban testing of warhead components
that did not result in a nuclear yield--known as zero-yield,
sub-critical, or hydrodynamic tests.
Russia had declared a moratorium on nuclear testing in 1990,
and the United States followed after tests in September 1992.
The United Kingdom ceased testing after 1991. French and Chinese
testing continued for several years, both conducting their last
tests in 1996--in time to sign and comply with the the CTBT.
(Note 2)
While French testing had become far less of concern to the
United States Intelligence Community by 1990 than it had been
in the 1960s and 1970s, Chinese nuclear activities, particularly
the activities at the Lop Nur test site, remained a significant
target of U.S. intelligence collection efforts--which employed
open sources, clandestine human sources, overhead imagery, signals
intelligence and measurement and signature intelligence. (Note
3)
Despite the Russian moratorium that began before the collapse
of the Soviet Union and continued under President Boris Yeltsin
and Russia's signature of the CTBT, the U.S. continued to closely
monitor Soviet-Russian test sites at Semipalatinsk and Novaya
Zemlya. With the breakup of the Soviet Union, only Novaya Zemlya
would remain inside Russian territory and become the sole Soviet
test site. The activities at that site during the decade--often
related to sub-critical tests, as well as occasional seismic
events in the vicinity of the test site, along with the continued
U.S. interest in Russian nuclear weapon developments, guaranteed
that U.S. spy satellites and other technical collection systems
would continue to be instructed to gather data on activities
at Novaya Zemlya. (Note 4)
Indeed, there would be suspicions and charges--first in 1996
and even more seriously in 1997--that Russia had, despite its
commitments, conducted a test at Novaya Zemlya. Thus, on August
16, 1997 a seismic signal from the vicinity of Novaya Zemlya
registered at 3.2 on the Richter scale--consistent with a very
small blast of between 0.1 and 1.0 kiloton, which might indicate
scaled-down tests of a warhead primary. Since satellite imagery
had been showing unusual levels of activity at the test site,
there were fears that Russia had tested a nuclear device. While
those fears would eventually be laid to rest by further analysis
of the data, including by an outside review group, the initial
suspicions generated considerable press reporting and intelligence
analysis. (Note 5)
The product of the collection efforts against the Russian and
Chinese test sites and related activities throughout the 1990-2000
period informed a variety of intelligence products - including
items in national intelligence products such as the National
Intelligence Daily and Senior Executive Intelligence
Brief, articles in CIA periodicals such as Science
and Weapons Review and Proliferation Digest, and
stand-alone analytical studies. The ones presented below were
obtained as the result of Freedom of Information Act requests
filed as part of the author's research for Spying
on the Bomb: American Nuclear Intelligence from Nazi Germany
to Iran and North Korea (W.W. Norton).
Besides the report of review panel established to consider the
possibility that Russia had conducted a nuclear test in August
1997 (Document 25), the briefing book includes
documents related to possible Chinese attempts to develop a
nuclear artillery shell (Document 20, Document
21), the impact of the impending Comprehensive Test Ban
Treaty on Chinese testing (Document 9),
Russia's recovery of a nuclear device that had been left in
a tunnel in the Semipalatinsk test site (Document
13, Document 17), and Russian interests
in developing low-yield nuclear weapons for its Ground Forces
(Document 31, Document
32, Document 33).

test.
