New excavation work

Excavation near North Korea's 5MW reactor at Yongbyon, was observed in an image taken on September 26, 2010 from the GeoEye 1 satellite.

The imagery shows what appears to be a 100 by 150 feet (30 x 45 meters) excavation which occupies an area 15,000 square feet (or 150 square meters) in space. As of early October 2010, the purpose of the excavation was unknown.

It is important to note that there is nothing in the imagery yet that indicates a purpose for the space.

This does not, however, exclude the possibility that the excavation is a prelude to a new cooling tower or pumping station being built at that site; thereby allowing North Korea to restart the 5MW reactor and continue to extract additional plutonium from its supply of fuel rods.

Additional clarity will be provided in the forthcoming months and years if footings and concrete foundation are poured and/or any above ground piping or trenching are detected in subsequent satellite imagery, as this would suggest the presence of below-ground pipes from the reactor to the cooling tower, or a pumping house to the river nearby to the east, and indicate a possible restart to the 5MW reactor.

This closer view of a satellite image taken on 26 September 2010 shows the recent excavation of the 15,000 square foot hole in the ground. when fully finished an estimated 450,000 cubic feet of earth will have been removed from the site. Also visible in the imagery are a new building to the left of the activity site as well as a newly poured concrete pad in the upper left.
