Build-up Exercise for IFE14 in September 2012 in Bruckneudorf, Austria

Build-up Exercise for IFE14 in September 2012 in Bruckneudorf, Austria


IFE14 was an Integrated Field Exercise to simulate an almost entire on-site inspection (OSI) in Jordan from 3 November to 9 December 2014 organized by the Preparatory Commission for the Comprehensive Nuclear-Test-Ban Treaty Organization (CTBTO). During IFE14 the inspection team conducted a meticulous search of a clearly defined inspection area to establish whether or not a nuclear explosion had been conducted. The exercise was in response to a technically realistic and stimulating but fictional scenario.

On-site Inspections

Upon entry into force of the Comprehensive Nuclear-Test-Ban Treaty (CTBT), an on-site inspection (OSI) will become the final verification measure conducted to ascertain whether or not a nuclear explosion has taken place.

Any State Party will then have the right to request the inspection of an area where it believes a nuclear explosion may have been carried out in violation of the CTBT. The Executive Council will need to approve any request before it is carried out. 

Inspection Phases

An inspection follows a series of clearly defined steps and timelines. During IFE14 the organization exercised each phase of an OSI: starting with the receipt of the request, through the inspection, to the return of all equipment and personnel.

The IFE14 Host Country

The CTBTO selected Jordan's offer to host IFE14. The exercise was conducted during November and December 2014 in an inspection area of up to 1,000 km2 on the banks of the Dead Sea. This was the second major exercise in the country after Directed Exercise 2010.


Inspection Techniques

The Treaty defines specific activities and techniques that can be applied during an OSI, starting with less intrusive and moving to more intrusive techniques. Learn more about the techniques used in IFE14.

The IFE14 Build Up Exercises

In preparation for IFE14, the organization conducted a series of build-up exercises to practise each phase of an OSI within realistic time frames.

Training Inspectors

The CTBTO is involved in a continuous process of developing a training programme of inspectors for adoption upon entry into force of the CTBT. The training programme is regularly tested on surrogate inspectors, a number of whom participated in IFE14.

In September 2013, a training conducted in Sicily, Italy, familiarized participants with special airborne techniques (video) that were used during IFE14.

In advance of IFE14, the organization also trained individuals from the host country to prepare them to fulfill their various roles in the exercise.
