The viruses would remain viable until the unit is destroyed. Most likely the unit would test positive for the presence of these viruses shortly after the donation and then placed in a biohazard container and destroyed. In the US, the tests to detect the presence of these viruses are highly sensitive and reliable and if I needed a blood transfusion today or I would die, then I would definitely trust our blood supply to be safe. There is always a risk of getting something from a blood transfusion - because there is nothing that is 100% guaranteed - but the greatest risk is currently getting the wrong unit of blood (wrong blood type!).

The blood would not end up in the container, because donors are tested before they donate. But if it did end up there, the blood is then tested again, and when it showed positive, it would be destroyed. So that's how long.
If you are really asking about some other means of transmission, but don't want to say so, HIV cannot live very well at all outside of the body. In the case of sharing needles, I would think that it is in blood, the transfer is quick, so that'd be pretty close to being in the bloodstream.
Heb C is a tough little bugger, and survives in blood on surfaces pretty well. I don't know about Hep B, but search on "Hepatitis" and there are hundreds of reputable fact sheets available (CDC and NIH have good information.)

The best information I have found on this is that if the blood is frozen, these viruses can survive for years if properly preserved.
