The effect of putting small amounts of Plutonium 239 with U-238 is converting U-238 to:?
a. TH-239
b. PA-239

e. PB 206

D.
Pu-239 releases neutrons. U-238 absorbs neutrons. Most of the U-238 spits the neutron back out. Some of the U-238 retaains the neutron and becomes U-239. By beta decay, U-239 becomes Pu-239.

The Pu-239 is the fuel for a reactor. The U-238 is the breeding material to produce more Pu-239

The correct answer is D.
when uranium 238 is exposed to neutrons it does not fission. the neutron lands on the nucleus of the uranium and degrades to a proton and an electron thus becoming plutonium 239
I model critical mass equations for a living in a nuclear fuel rod production plant.

You would be doping U238 into an isotope of weakened Uranium
