Scientists Study Nuclear Blast Detection System From Thursday, March 6, 2008 issue.

Scientists Study Nuclear Blast Detection System


The commission aimed at implementing the Comprehensive Nuclear Test Ban Treaty announced today it is working to verify whether a global system for detecting atomic blasts would function effectively, Agence France-Presse reported (see GSN, Feb. 26).

Sixty scientists from 30 countries met in Vienna, Austria, this week to launch an 18-month evaluation of the “readiness and capability” of a detection system being built to monitor the test ban.  The verification network links roughly 340 facilities around the world.

The “verification regime has now reached a very advanced stage and is nearing completion and a comprehensive assessment has never been done before,” said Tibor Toth, who heads a preparatory commission set up in advance of the Comprehensive Nuclear Test Ban Treaty Organization.  The organization would be formed only after the agreement has been ratified by 44 key nations with nuclear power or research reactor capability.

Nine key nations have yet to approve the treaty, including known or suspected nuclear-weapon holders China, India, Israel, Pakistan and the United States. 

Among the major nations that have signed off on the treaty are France, Russia and the United Kingdom

Toth said “the time is ripe” to perform an assessment.  Results are scheduled to be circulated at an international conference in the Austrian capital in June 2009, he said.

“The system has to be well calibrated, reliable and secure,” said one participating research scientist, Yves Caristan.

“We need to ask ourselves: does the system deliver what we expect it to deliver,” added Caristan, who directs the Saclay Research Center at the French Atomic Energy Commission (Agence France-Presse/Spacewar.com, March 6).
