Wow, somehow I totally missed that Sig Hecker published the North Korean disablement steps in his last trip report from North Korea :

The following constitute the 12 disablement actions as defined by Yongbyon officials:

Fuel Fabrication Facility

1) Removal and storage of all three uranium ore concentrate dissolver tanks.
2) Removal and storage of all seven uranium conversion furnaces, including storage of refractory bricks and mortar sand.
3) Removal and storage of both metal casting furnaces and vacuum system, and removal and storage of eight machining lathes.
4) Storage of the remaining UO3 powder in bags with monitoring by IAEA (this constitutes nearly five tons of powder).

5 MWe reactor

5) Cut and removal of portions of steel piping of the secondary cooling loop outside the reactor building.
6) Removal of the wood interior structure of the cooling tower.
7) Discharge of 8000 spent fuel rods.
8) Removal and storage of the control rod drive mechanisms.

Reprocessing Facility

9) Cut cable and removal of drive mechanism for trolley that moves spent fuel caskets from the fuel receiving building into the reprocessing facility.
10) Cut two of the four steam lines into the reprocessing facility.
11) Removal of the crane and door actuators that permit spent fuel rods to enter the reprocessing facility (at Level -1).
12) Removal of the drive mechanisms for the fuel cladding shearing and slitting machines (at Level -1).

The operational definition of “disablement” is to make it more difficult, but not impossible, to restart the nuclear facilities. As of Feb. 14, 10 of the 12 disablement actions identified by the DPRK had been completed. The discharge of the reactor fuel rods from the 5 MWe reactor (#7) was intentionally slowed down by the DPRK. The removal of the control rod drive mechanisms (#8) will be completed once all fuel rods are discharged.

That more or less squares with what I’ve been heard. (The State Department, by the way, has been showing pictures of steps 3, 5, 6, 9, and 11.)

Really good stuff.
