OSI Directed Exercise 2010

The OSI Directed Exercise (DE10) was conducted in the Dead Sea area in Jordan.

This OSI Directed Exercise (DE10) took place in Jordan in November 2010 and tested ground-based visual observation procedures and communications during an on-site inspection (OSI). The exercise was held under the patronage of Her Royal Highness Princess Sumaya bint El Hassan with the support of the Natural Resources Authority of Jordan.

Forty-five people from 14 State Signatories took part in the exercise which helped validate and develop standards and procedures for the visual observation and communication elements of an on-site inspection.

Exercise objectives and results

During on-site inspections, communications are a key factor. This photo shows the setting up of a new type of inflatable satellite antenna.

Many lessons were identified during DE10 and have been incorporated into the ongoing development of the OSI regime. These results included:

  • Validating the standard operating procedures for ground based visual observation.
  • Achieving synergy between the visual observation sub-team and the rest of the inspection team.
  • Producing the standard operating procedures for communication during an OSI by testing the communication concept for the inspection team.
  • Demonstrating the reliability of communication between all stakeholders.

Director of the Exercise, Matjaž Prah, said that the focus of the simulation was to “test ground visual observation techniques and communications, to help prepare inspectors and fine tune inspection methodology.” Prah explained they looked for observable signatures which could be connected to a possible nuclear explosion. “There were very specific observable geophysical features that could be linked to a possible nuclear explosion: landslides, depressions, craters and faults, for example,” he described.

Jordan offered to host the exercise in a 1,000 km2 zone beside the Dead Sea and was selected due to comparable natural geological features within the inspection area that could be found, if in fact, there had been a nuclear test. “The area around the Dead Sea is quite interesting because of very specific geological features, like sinkholes for example, which can look similar to the depressions that are formed after a nuclear test,” Prah said.
