Pumps are used.
However, as Kelvin now understands above; the materials that get activated in the reactor are principally beta-emitters.
Beta-emitters emit electrons. In order to make something radioactive; you have to change the nucleus. Electrons from beta emitters are NOT part of the nucleus.
So the radiation from beta-emitters CAN NOT make something radioactive.
To make something radioactive; it has to be exposed to neutrons.
The neutrons are IN the reactor core.
The pumps are OUTSIDE the reactor and NOT IN the reactor.
So the material that comprises the primary reactor coolant pumps is NOT made radioactive.
Understand???
The good thing about science is that it is true, whether or not you believe in it.
