Although North Korea does not yet have possession of the money that’s been holding up the show:

North Korea has left untouched US$25 million unfrozen in a Macau bank…

It appears they are at least making preparations for the reactor shutdown:

A leading diplomatic source said, “The U.S. took satellite images which captured unusual movements of people and vehicles around the cooling tower and parking lot in the Yongbyon nuclear facility. Washington thinks it is highly likely that those activities are a part of N. Korea’s operations to close down the nuclear facility.”

Of course these are preparations that could and should have been made days if not weeks ago. But this is part of North Korea’s game. At any rate, it is expected that North Korea would shutdown the reactor, if for nothing else it’s the only way that South Korea will release the 50k tons of heavy fuel oil and other aid.

The real issue that has been overlooked by most if not all mass media is that the 13 February deal (DOC) calls for, “The DPRK will discuss with other parties a list of all its nuclear programs…” This item, in my opinion more important than the shutting down of Yongbyon, has not yet been addressed and had the same 14 April deadline.
