I was in fact thinking it was less than 60% from power plants, especially considering that France has nuclear weapons. Regarding the 30 year half life time. That's somewhat misleading because while it might be true different waste products are often mixed with each other so one has to plan for the longest lifetime parts. Talking about reprocessing (recycling is a complete misnomer), did you know that reprocessing greatley increases the amount (volume) of nuclear waste? And that it is not really economical, unless you want to make nuclear weapons.
