5 Megawatt (electric) Nuclear Reactor.


Cooling tower for 5 MW reactor prior to its June 2008 demolition.


A view up at the empty interior of the cooling tower. All of the cooling and evaporative mechanisms have been disassembled and removed.


A view of the ground level of the cooling tower showing all structures having been removed.


A North Korean official in front of refractory bricks and mortar dust removed from the seven uranium metal production furnaces awaiting disposal as radioactive waste.


Nearly five tons of UO3 (an intermediate product in the fabrication of uranium metal) collected from fuel fabrication facility and stored in plastic bags monitored by IAEA cameras.


Fuel fabrication facility. Empty pits which contained three uranium ore concentrate dissolver tanks, now removed and stored.


Location of one of the removed vacuum induction casting furnaces that shaped uranium metal ingots into fuel rod cores in preparation for machining and cladding the cores into fresh fuel rods.


Disabled equipment in storage at the fuel rod fabrication facility. This photo shows four spare fuel rod casting vessels in storage and dissolver tanks.


Right: Location where the shearing machine was formerly located. Left: Orifice where the removed shearing machine cutter knife entered the hot cell.


Location where the receiving cell isolation door actuator mechanism was formerly located. The isolation door separates the receiving hot cell from the transfer tunnel from the spent fuel receiving building.


Location where two cranes were formerly located. These cranes transferred the spent fuel basket into the receiving hot cell and positioned the basket at the shearing station.


Stored equipment removed from reprocessing plant.


Former location of a motor mechanism which operated a trolley that transferred the spent fuel basket from the receipts building into the reprocessing plant.


The winch room of the reactor showing the winch for moving the fuel baskets and an electronics cabinet containing U.S. and IAEA electronics monitoring the passage of every fuel rod being discharged from the core.


Fuel fabrication facility. Empty machine shop from which lathes have been removed. Exhaust ducts are shown still in place.


Fue fabrication facility. Empty furnace pits for the seven uranium metal production furnaces.


Fuel fabrication facility. In the picture is Siegfried Hecker, examining machining lathes removed from machine shop.
