Nitrogen pumping into a Nuclear Reactor- how does that work
(OP)
I am sure its easier to pump lots of Nitrogen (easy availability) but how does it improve cooling efficiency?

Nitrogen is used to inert the atmoshere in primary containment. In this case to midagate the possiblity of a combustable mixture.

They are not pumping nitrogen into the reactor vessel. They are pumping it into the structure around the reactor. This structure is normally called "primary containment," but is sometimes referred to as as "drywell" because it doesn't contain water. Around the drywell there is a second structure, sometimes referred to as "secondary containment."
This picture (http://en.wikipedia.org/wiki/File:Reaktor.svg), which came from Wikipedia shows the various structures. The reactor vessel (which is a pressure vessel) is in yellow. The primary containment is outlined in orange. Notice that the bottom part, has water in it -- this is sometimes called the "wetwell." The secondary containment, which is where the explosions occurred is the whole building. The upper portion is the gird and panel section that appeared to explode at Fukushima. The place with a "5" looks to be the spent fuel pool. If you look on the NRC's website(h
The primary containment at a boiling water reactor is normally filled with nitrogen for the reason rmw mentioned. So they're trying to maintain the normal condition.
