An Active Interrogation Technique Based on Photofission for Non-destructive Assay of Used Nuclear Fuel

Creator:: Wen, Xianfei
Abstract:: High-energy delayed γ-rays from photofission were demonstrated to be signatures for detection and identification of special nuclear materials. Such γ-rays were measured in between linac pulses using independent data acquisition systems. A list-mode system was developed to measure low-energy delayed γ-rays after irradiation. Photofission product yields of ²³⁸U and ²³⁹Pu...

Optimization of in-core nuclear fuel management in a pressurized water reactor

Creator:: Stout, Richard Bartholomew
Abstract:: Fuel loading patterns which have a minimum power peak are economically desirable to allow power reactors to operate at the highest possible power density and to minimize the possibility of fuel failure. A computer code called SHUFLE was developed for pressurized water reactors which shuffles the fuel in search of...

Modeling the thermal effects of fabricated fuel-to-cladding gap in fast reactor fuel

Creator:: Baker, Ronald Blair
Abstract:: This report presents a refined method for the calculation of fuel centerline temperatures and the linear-heat-rating-to-incipient melting, ' Q'[subscript m], of mixed-oxide fuel typical of that to be used in the Fast Flux Test Facility and in Liquid Metal Fast Breeder Reactors. Of primary concern are the effects of the...

An assessment of describing function methods applied to reactor fuel performance analysis

Creator:: Nielsen, Larry H.
Abstract:: Large digital computer reactor fuel performance codes perform repeated calculations of temperature profiles during transients. The thermal response is required to calculate the mechanical behavior. This mechanical response in turn feeds back to the thermal calculations through mechanisms such as fuel swelling or shrinking, causing changes in the fuel-clad gap...

Stochastic simulation of sphere beds and the effect of packing density on the thermal conductivity of sphere pac nuclear fuels

Creator:: Henke, Robert K.
Abstract:: The establishment of any thermal model of reactor fuel requires a thorough understanding of the behavior of the thermal conductivity. This is especially true in the case of sphere pac fuels where the conductivity is a function of many variables beyond those normally affecting conventional fuels. One of these variables,...

Thermal and mechanical behavior of sphere pac fuel

Creator:: Montgomery, Scott D.
Abstract:: The use of advanced concepts can make the nuclear fuel cycle more efficient by allowing pins to be operated at high powers and to higher burnups. Among the more promising concepts in advanced fuels is sphere pac fuel. In a first attempt to bring together models describing individual phenomena, the...

Direct shear testing of UO₂ sphere-pac nuclear reactor fuel

Creator:: Jenks, Richard P.
Abstract:: The design, development, and utilization of a direct shear test apparatus is presented in this thesis. The effectiveness of the device for determining the friction angle stress state parameter is studied. Two materials, alumina and uranium dioxide, were tested. Alumina microspheres were employed in the initial experiments to simulate the...

Development of a Strain Gage Program for the Measurement of Strain on Prototypic, Plate-type, High Performance Research Reactor Fuels under Flow Testing

Creator:: Weiss, Aaron W.
Abstract:: A large, multi-year experimental program has been conducted to develop a strain gaging program for application to the flow testing of prototypic, plate-type fuel for high performance research reactors. This test program has resulted in the selection of appropriate strain gage construction, adhesives, and protective coatings to allow the acquisition...
