Book Description
Proceedings of a symposium organized in co-operation with ANS, ESARDA, INMM and the Nuclear Society International (Moscow), Vienna, 14-18 March 1994. Presented at this symposium were: the findings in Iraq by the Action Team established under United Nations Security Council resolutions, South Africa's decision to join the Treaty on the Non-Proliferation of Nuclear Weapons (NPT), details of the IAEA-Argentina-Brazil-ABACC Quadripartite Safeguards Agreement, and measures following the break-up of the former USSR into newly independent States. Special emphasis was given to the verification of a State's declaration as well as detection of undeclared activities. In addition to covering recent developments, the symposium considered fundamental changes stemming from converging relationships between nuclear arms reductions and the civil use of plutonium, unattended computer based verification systems and other safeguards concepts for the future, and the review and extension of the NPT in 1995.

Book Description
Nondestructive measurements of x-ray and gamma-ray emissions can be used to determine the abundances of various actinides in a sample. Volume 1 of this report describes the methods and algorithms we have developed to determine the relative isotopic abundances of actinides in a sample, by analyzing gamma-ray spectra obtained using germanium detector systems. Volume 2 is a guide to using the MGA (Multiple Group Analysis) computer program we have written to perform plutonium isotopic analyses. This report contains a listing of the FORTRAN instructions of the code.

Book Description
DOE/NNSA and IRSN collaborated on a study of gamma-ray instruments and analysis methods used to perform isotopic measurements of special nuclear materials. The two agencies agreed to collaborate on the project in response to inconsistencies that were found in the various versions of software and hardware used to determine the isotopic abundances of uranium and plutonium. IRSN used software developed internally to test the MGA and FRAM isotopic analysis codes for criteria used to stop data acquisition. The stop-criterion test revealed several unusual behaviors in both the MGA and FRAM software codes.

Book Description
We describe the characteristics and features and demonstrate the performance of a new code (FRAM) for determining the isotopic composition of plutonium using gamma-ray spectroscopy. This versatile code can measure an extremely wide range of isotopic compositions and is extremely easy to tailor to specialized measurement conditions. Measurement precision, accuracy, and throughput are significantly improved over previous Los Alamos National Laboratory (LANL) codes. 13 refs., 2 figs., 4 tabs.
