About 4.5 kg (9lb 9oz) of Pu-238 per radioisotope thermoelectric generator (RTG).

The Voyager spacecraft each had three RTGs.

So 13.5 kg (29lb 8oz) of Pu-238.

The Multihundred-Watt radioisotope thermoelectric generator (MHW RTG) is a type of US radioisotope thermoelectric generator (RTG) developed for the Voyager spacecraft, Voyager 1 and Voyager 2.

The Wiki item provides details of the power required and generated.
