How much of a space shuttle is reused?

Henrik Hansson asked the Naked Scientists:
   
How much of the space shuttle is actually the same as last time it was flying? I have heard that much, or even most, of a shuttle is replaced between the flights.

What do you think?

Pretty much the only parts that are replaced are the external tank and the fuel inside, and the solid fuel inside the 2 SRB's ( Solid Rocket Boosters) on the side of the tank. Also replaced are coolant water and ammonia for cooling during ascent and descent, and fuel used in orbit. Pretty much everything aside from that is tested, refurbished and flown again some time later. Only parts that fail are replaced, which is the major reason that the shuttle costs so much to refurbish, as so many of these parts were designed, manufactured and last ordered in the 1970's, and many of the suppliers have merged, moved, closed, changed products or just disappeared over the years, leaving the parts having to be made again from either the original designs, where available, or made "as per sample - just not broken".
