Division Spotlight
Decommissioning & Environmental Sciences
The mission of the Decommissioning and Environmental Sciences (DES) Division is to promote the development and use of those skills and technologies associated with the use of nuclear energy and the optimal management and stewardship of the environment, sustainable development, decommissioning, remediation, reutilization, and long-term surveillance and maintenance of nuclear-related installations, and sites. The target audience for this effort is the membership of the Division, the Society, and the public at large.

College students help develop waste-measuring device at Hanford
A partnership between Washington River Protection Solutions (WRPS) and Washington State University has resulted in the development of a device to measure radioactive and chemical tank waste at the Hanford Site. WRPS is the contractor at Hanford for the Department of Energy’s Office of Environmental Management.

The reaction cross sections of 55Mn(n, γ)56Mn and 65Cu(n, γ)66Cu have been measured over a neutron energy range from 1 keV to 4 MeV. The racetrack microtron accelerator-based neutron source was used for the cross-section measurement, which generates a neutron spectrum from 1 keV to 4 MeV. Moreover, the cross-sections of the nuclear reaction were calculated using TALYS-1.2 and EMPIRE nuclear codes. It has been observed that the experimental cross sections of manganese and copper are 8.5 mb and 4.5 mb, respectively, and they are quite close to the TALYS, EMPIRE, and evaluated data of ENDF/B-VII.0, ENDF/B-VII.1, JEFF-3.1.2, and EXFOR. For (n, γ) reactions studied in the present work, the results obtained using TALYS and EMPIRE codes are in agreement with literature values when the radiative capture width Гγ and the width fluctuation parameter, respectively, functioned by being adjusted to a suitable value. Further, the deviation factor for measured and theoretical cross sections has also been determined and it is found to be better for the 55Mn(n, γ)56Mn reaction obtained using TALYS compared to EMPIRE.
