Yep, stainless steel and concrete I believe. The media likes to make it look like its going to blow up and spew radiation all over the world.

Experts are saying the only radiation that is likely to keep happening is from the venting they have to do to keep cooling it.

This puts the radiation into perspective too:

The NRC’s public radiation dose limit is 100 mrems annually. The average U.S. public exposure from the commercial nuclear fuel cycle, including nuclear power plant operations, is less than 1 mrem per year.

The average American receives more than 600 millirems of radiation exposure annually—about half from naturally-occurring sources and the rest from medical applications, such as CT scans and X-rays.
