That's 5-6 billion over ~140 years. The operating costs of the Swiss Zwilag facility are similar. Storing the waste on site is cheap as long as the reactor is operational. The facilities and the staff are there anyway. It gets more expensive once the reactor stops operating. You can't just leave the high-level waste there for anyone to steal, and you should also work proactively to prevent leaks.
