Division Spotlight
Nuclear Criticality Safety
NCSD provides communication among nuclear criticality safety professionals through the development of standards, the evolution of training methods and materials, the presentation of technical data and procedures, and the creation of specialty publications. In these ways, the division furthers the exchange of technical information on nuclear criticality safety with the ultimate goal of promoting the safe handling of fissionable materials outside reactors.

Improvements in a technique for deducing the spectrum of fast neutrons from the measurement of proton recoil tracks in nuclear emulsions are described. The source of neutrons may be anisotropic. Tests were made by placing Ilford L4 emulsion plates in an assembly of depleted uranium (0.21% 235U) in which neutrons are produced by photofission. The photofission was induced by bremsstrahlung produced when a pulsed 30-MeV electron beam from a LINAC hit a target of depleted uranium within the assembly. Special development with amidol developer was used to reduce chemical fog and gamma-ray background in the emulsions, permitting a measurement of proton tracks down to about two microns. The neutron spectrum from ≈ 0.3 to 2.5 MeV is deduced from the measurements. Computer programs were developed to make the calculations. Results up to ≈ 0.9 MeV are compared with the neutron spectrum measured by time-of-flight techniques. Satisfactory agreement is obtained.
