Download or read book NWIS MEASUREMENTS FOR URANIUM METAL ANNULAR CASTINGS written by and published by . This book was released on 1998 with total page 46 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report describes measurements performed with annular uranium metal castings of different enrichments to investigate the use of 252Cf-source-driven noise analysis measurements as a means to quantify the amount of special nuclear material (SNM) in the casting. This work in FY 97 was sponsored by the Oak Ridge Y-12 Plant and the DOE Office of Technology Development Programs. Previous measurements and calculational studies have shown that many of the signatures obtained from the source-driven measurement are very sensitive to fissile mass. Measurements were performed to assess the applicability of this method to standard annular uranium metal castings at the Oak Ridge Y-12 plant under verification by the International Atomic Energy Agency (IAEA) using the Nuclear Weapons Identification System (NWIS) processor. Before the measurements with different enrichments, a limited study of source-detector-casting moderator configurations was performed to enhance the correlated information. These configurations consisted of a casting with no reflector and with various thicknesses of polyethylene reflectors up to 10.16 cm in 2.54 cm steps. The polyethylene moderator thickness of 7.62 cm was used for measurements with castings of different enrichments reported here. The sensitivity of the measured parameters to fissile mass was investigated using four castings each with a different enrichment. The high sensitivity of this measurement method to fissile mass and to other material and configurations provides some advantages over existing safeguards methods.

Book excerpt: This summary describes measurements performed on four annular uranium metal castings of different enrichments to investigate the use of 252Cf-source-driven noise analysis measurements as a means to quantify the amount of special nuclear material (SNM) in the casting. Previous measurements and calculational studies have shown that many of the signatures obtained from the source-driven measurement are sensitive to fissile mass. Measurements were performed to assess the applicability of this method to standard annular uranium metal castings at the Oak Ridge Y-12 plant under verification by the International Atomic Energy Agency (IAEA) using the Nuclear Weapons Identification System (NWIS) processor. The sensitivity of the measured parameters to fissile mass was investigated using four castings each with a different enrichment. Preliminary results are presented that demonstrate the sensitivity of the measured parameter to fissile mass. However, these preliminary results do not represent an optimized measurement configuration but are intended to demonstrate possible applications of this method.

This book was released on 2002-09-28 with total page 132 pages. Available in PDF, EPUB and Kindle. Book excerpt: The U.S. Department of Energy (DOE) disposes of plutonium-contaminated debris from its 27 nuclear weapons facilities at the Waste Isolation Pilot Plant (WIPP), an underground repository in Carlsbad, New Mexico. After four years of operational experience, DOE has opportunities to make changes to the costly and time-consuming process of "characterizing" the waste to confirm that it is appropriate for shipment to and disposal at WIPP.  The report says that in order to make such changes, DOE should conduct and publish a systematic and quantitative assessment to show that the proposed changes would not affect the protection of workers, the public, or the environment.

Download or read book Near Surface Disposal Facilities for Radioactive Waste written by International Atomic Energy Agency and published by . This book was released on 2014 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This Safety Guide provides recommendations on how to meet safety requirements on the disposal of radioactive waste. It is concerned with the disposal of solid radioactive waste by emplacement in designated facilities at or near the land surface. The Safety Guide provides guidance on the development, operation and closure of, and on the regulatory control of, near surface disposal facilities, which are suitable for the disposal of very low level waste and low level waste. The Safety Guide provides guidance on a range of disposal methods, including the emplacement of solid radioactive waste in earthen trenches, in above ground engineered structures, in engineered structures just below the ground surface and in rock caverns, silos and tunnels excavated at depths of up to a few tens of metres underground. It is intended for use primarily by those involved with policy development for, with the regulatory control of, and with the development and operation of near surface disposal facilities.
