Call for Irradiation, Post-irradiation Examination & Beamline Proposals


Applications are submitted annually through the Consolidated Innovative Nuclear Research Funding Opportunity Announcement.
More information is available on the Nuclear Energy University Programs (NEUP) website.

The Nuclear Science User Facilities (NSUF) is seeking proposals for projects that will utilize NSUF irradiation, post-irradiation examination and critical facility capabilities, including those of our partner institutions: Illinois Institute of Technology, MIT, North Carolina State University, Oak Ridge National Laboratory, Pacific Northwest National Laboratory, Purdue University, University of California, Berkeley, University of Michigan, University of Nevada, Las Vegas and University of Wisconsin.

Proposals submitted should directly support Department of Energy Nuclear Energy research and development programs. Information on these programs, including the Light Water Reactor Sustainability Program, Fuel Cycle Research & Development, Advanced Modeling and Simulation, Next Generation Nuclear Program (NGNP [refer to Gen IV on the DOE Web page]), and the Generation IV Nuclear Energy Systems Initiative can be found on the Office of Nuclear Energy website

While priority will be given to proposals that further the direction of DOE's nuclear energy research programs, the NSUF will consider all technically feasible proposals for scientific merit and selection. 

NSUF offers the following types of experiments:

  • Static Capsule experiments that may contain a number of small samples, or if a large position is used, it may contain engineered components. Temperature within the capsule is set by providing a gas gap with a known thermal conductance. Thermal bonding media such as liquid metals may be used in capsule experiments to keep temperatures uniform inside the experiment with double encapsulations. Passive temperature monitors such as SiC specimens may be used for postirradiation verification of operating temperature. Flux-wire monitors in the experiments can give good measurements of neutron fluence at particular locations. Capsules may be up to 122 cm (48 in.) long, and may be irradiated in any of the positions in the core, including the flux traps.
  • Instrumented Lead experiments that allow on-line monitoring and control of experiment temperature.  Instrumented lead experiments contain individual capsules that can be independently monitored and controlled. Temperature within each capsule is actively controlled by varying the thermal conductance of the gap gas by adjusting the gas mixture (for example, varying the ratio of helium to neon) in a circumferential gas gap.
  • Experiments that seek to examine specimens previously irradiated as part of previous U.S. Department of Energy fuel and material development efforts. These specimens include both steel specimens irradiated in fast reactors and ceramic materials irradiated in ATR. These specimens may be of interest to researchers investigating specific phenomena in detail or in investigating the irradiation behavior of novel materials. A list of specimens that are available are listed in the sample library.
  • Experiments with Synchrotron Radiation at the Advanced Photon Source MRCAT: Research proposed includes the use of the facilities at the Materials Research Collaborative Access Team (MRCAT) beamline located in the Advanced Photon Source facility at Argonne National Laboratory.
