Neely Nuclear Research Center named a nuclear historic landmark
The American Nuclear Society recently announced the designation of three new nuclear historic landmarks: the Hot Fuel Examination Facility, the Neely Nuclear Research Center, and the Oak Ridge Gaseous Diffusion Plant. Today’s article, the second in a three-part series, will focus on the historical significance of the Neely Nuclear Research Center.

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.
