The last days of Hallam
The Hallam nuclear power plant, about 25 miles southwest of Lincoln, Neb., was an important part of the Atomic Energy Commission’s Reactor Power Demonstration Program. But in the end, it operated for only 6,271 hours and generated about 192.5 million kilowatt-hours of electric power during its short, 15-month life.

The prompt neutron emission spectrum from the spontaneous fission of 252Cf has been measured for the 0.124- to 15.0-MeV energy range. In the measurement program, seven separate measurements were made of the spectrum between 7.0 and 15.0 MeV using a plastic scintillator as the neutron detector. For the 0.124- to 2.66-MeV energy range, a 6Li glass scintillator was used as the neutron detector. The data are presented with respect to a Maxwellian distribution with T = 1.42 MeV. Some positive and negative deviations with respect to this distribution have been observed.
