For every three U-235 nuclei that fissions in a nuclear reaction, two nuclei of Pu-239 waste are produced. Suppose you leave a 100W light on for 1 hour. If your electricity comes from a 33% efficient nuclear power plant, how many Pu-239 nuclei are produced as a result of your leaving the light on? (Each U-235 nucleus that fissions produces about 30 x 10^-12 J of energy)
