You don't know the science. The long lived isotopes, i.e. the actinides; are also REACTOR FUEL.
When you recycle the long-lived isotopes back to the reactor, they get burned as fuel ( as Dr. Till describes ), and you end up with short-lived fission products instead of long-lived actinides.
It's not just the reprocessing. Reprocessing just allows you to RECYCLE. The recycle means that you can BURN the long lived isotopes to short-lived fission products.
The reason the USA needs Yucca Mountain is that the US Congress in 1978 OUTLAWED the reprocessing / recycle in the USA. Additionally, in the Nuclear Waste Policy Acts of 1982 and 1987; the Congress said that it would be the policy of the USA NOT to reprocess / recycle but instead to use a "once through" cycle with geologic disposal in a repository which is Yucca Mountain.
Evidently you don't understand that the waste problem the USA has is driven NOT by the technology; but by POLITICAL decisions.
I'm a SCIENTIST; and I am NOT believing any industry propaganda. YOU are the one that is PARROTING anti-nuclear propaganda that I've heard many times before.
The embrittlement of reactor vessel metal is VERY WELL STUDIED by the SCIENTIFIC and ENGINEERING communities; so there's no need to have to rely on industry. My data is from SCIENTISTS and is NOT industry propaganda as you are IRRESPONSIBLY and RECKLESSLY accusing me of disseminating.
YOU are the one that is disseminating propaganda from the anti-nukes.
Pumps and Turbines have MOVING PARTS and they wear. That's why they need replacement.
The reactor vessel doesn't "wear" except in the sense of neutron embrittlement which is monitored and test for; and it is NOT BAD as expected.
