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.

Specimens of polymethylmethacrylate were welded by the neutron capture process using the 10B isotope. In general, very weak bonds were obtained, of the order of a 20-psi bond strength for naturally enriched boron. Bond strength increased with thermal-neutron fluence to 1015 n/cm2. At higher fluences the strengths decreased and the specimens became very brittle, presumably from radiation damage by the fast neutrons and gamma rays present in the radiation field of the reactor. Comparison of experiment with theory suggests that only a small fraction of the interface area is being welded.
