Uses

Plutonium-239’s critical mass undergoes a fissionable chain reaction, making it ideal for use as fuel for some types of nuclear reactors as well as to produce nuclear weapons. In the future it may be possible to use all the waste plutonium produced in the world to power small thermal electrical power plants that could be installed in each house to provide inexpensive and continuous household electrical power.

The heat capacity (8 to 350 K) of PuH1.9, heat capacity (340 to 600 K) of PuH2.0, and recommended thermodynamic properties of PuH2 to 600 K

The low-temperature heat capacity of PuH1.9, where the major plutonium isotope was 242Pu, has been determined from 8 to 350 K.The results of this investigation at 298.15 K have been adjusted to correspond to stoichiometric plutonium dihydride: PuH2.Standard molar thermodynamic quantities were obtained for PuH2 at T = 298.15 K: C0p,m(T) = (43.50 +/- 0.44) J*K-1*mol-1; S0m(T) = (72.84 +/- 0.73) J*K-1*mol-1; 0m(T) - H0m(0)> = (85.93 +/- 86) J*mol-1; and -0m(T) - H0m(0)>/T = (44.02 +/- 0.44) J*K-1*mol-1.These have been combined with experimental high-temperature heat capacities (340 to 600 K) of a sample of PuH2.0, where the major plutonium isotope as 239Pu, to give the thermodynamic functions of PuH2 over the temperature range from 298.15 to 600 K.
