A refractory material is one that retains its strength at high temperatures. ASTM C71 defines refractories as "non-metallic materials having those chemical and physical properties that made them applicable for structures, or as components of systems, that are exposed to environments above 1000 °F (800K, 500 °C)".
Such high temperatures are not met in water reactors, except in the fuel itself, which is in the form uranium dioxide. Is this what you mean? Some other types of reactors use high temperature gas for the coolant, though these are mostly experimental or prototypes at present. For example the pebble bed reactor uses fuel with the fissile material embedded in 'pebbles' of graphite, and in an inert helium atmosphere. In this case the graphite could be regarded as a refractory.

Uranium
Yes, uranium is the most important nuclear fuel now.
Generally, no. But nations capable of making nuclear power plants may be able to extend the technology to make weapons.
In power production (i.e. production of electricity) in nuclear power plants. It is also used in curing cancer.
Like any other technology, nuclear power plants surely has changed on many aspects, mainly security, eletronic management, leakage monitoring and others.
Because we do not have the technology to build them. It may be 50 years before we do.

Yes, witness the many hundreds of nuclear power plants in the world today, most of which have operated entirely safely.
Nuclear power plants produce electricity by using nuclear energy
We don't have the technology to make it last longer.
Fission. We don't have the technology to fuse atoms in a controlled way yet.

Absolutely. There was an earthquake of magnitude 9 which hit 4 nuclear power plants. Nuclear power is definitely technology, so the answer is yes.However, what most media focus on is some nuclear plants that withstood an earthquake a twice the designed magnitude, and nothing really serious happened. The earthquake and subsequent tsunami killed more then 10.000 Japanese and made many more homeless, so that should be much more important. And earthquakes and tsunamis are not technology related, so, if you consider the death toll, no what is happening in Japan is not technology related.
