Early Time Decay of Fission Product Mixtures Iv Gamma Ionization Chamber Measurements Following Thermal Neutron Fission of Pu 239


Book Description

DESCRIPTORS: (*Gamma rays, *Ionization chambers, Measurement following *Thermal neutrons, *Fission of *Plutonium, Radio active isotopes, Isotopic cross section.) (Radiochemistry, Analysis, Radioactive decay, Gamma emission.) (Test reactors, Nuclear reactions, Experimental data, Tables.) Gamma ionization chamber readings are given for the products of thermal neutron fission of Pu-239 for the period from 1 second to about 22 hours following fission. Using spectral data on U-235 fission products and ionization chamber efficieny with gamma energy, the energy release rate of Pu-239 fission products is determined as a function of time. The results are compared with those attained for U-235 fission products. (Author).







Safeguards Techniques and Equipment


Book Description

The 1990s saw significant developments in the global non-proliferation landscape, resulting in a new period of safeguards development. The current publication, which is the second revision and update of IAEA/NVS/1, is intended to give a full and balanced description of the safeguards techniques and equipment used for nuclear material accountancy, containment and surveillance measures, environmental sampling, and data security. New features include a section on new and novel technologies. As new verification measures continue to be developed, the material in this book will be reviewed periodically and updated versions issued.
