Data testing results for the ENDF/B-V Evaluated Neutron Data File. [20 spheres pulsed with 14-Mev neutrons]

Description: The ENDF/B-V Evaluated Neutron Data File has been tested for validity by comparing calculated and experimental values of k/sub eff/ for 66 critical assemblies and emission neutron spectra for 20 spheres that were pulsed with 14-MeV neutrons. 20 figures, 7 tables.

Report for General Research January 8, to April 30, 1951 (Alpha - Neutron Volume)

Description: An experimental, gamma-sensitive, coaxial radioelectric cell has been tested by the Control Section. It was found to be as precise as the rotating sample gamma counter but much faster and simpler to operate. A gamma-sensitive, radioelectric cell of improved design has been constructed for the 'Y' Section. A neutron sensitive radioelectric cell has been tested over a range of pressures with various filling gases and with several combinations of hydrogenous electrode backings. Neutron to gamma di… more

The Effect of Fast Fission on k

Description: The importance of fast neutron fission (i.e., fission caused by neutrons before being slowed down) was recognized by Szilard, and calculations similar to the present one have already been carried out by him, Feld, Ashkin, Wheeler, Wigner and others. The purpose of the present paper is to give a general formula for the contribution of fast fission to the multiplication constant, which will include all the cases already considered and will be applicable to more complicated geometries than those c… more

Understanding the role of defect production in radiation embrittlement of reactor pressure vessels.

Description: Comparative experiments using high energy (10 MeV) electrons and test reactor neutrons have been undertaken to understand the role that primary damage state has on hardening (embrittlement) induced by irradiation at 300 C. Electrons produce displacement damage primarily by low energy atomic recoils, while fast neutrons produce displacements from considerably higher energy recoils. Comparison of changes resulting from neutron irradiation, in which nascent point defect clusters can form in dense … more
