North Carolina State University's Graduate Fellowship In Nuclear Engineering (NCSU-GFINE)– 2018

Sponsor: US Nuclear Regulatory Commission

Start Date: 8/30/19

End Date: 8/29/23

Abstract

This proposal is a request for financial support for two graduate students every year for four consecutive years in nuclear engineering through the North Carolina State University’s Graduate Fellowship in Nuclear Engineering (NCSU–GFINE) program that helps to develop a highly talented and competent workforce with post-baccalaureate education capable of leading the nation’s charge to reinvigorate its nuclear industry. Every attempt will be made during the recruitment and selection processes to ensure that the sponsored students reflect the diverse groups that make up our nation’s populace. Moreover, the high academic standards inherent to NC State’s Department of Nuclear Engineering and the proposed selection formula will ensure the highest caliber of the sponsored fellows. These individuals will shepherd the design, construction, operation, and regulation of new and innovative nuclear facilities, while maintaining the safety and security of processes for the handling of requisite nuclear materials in the coming decades, a period crucial for the revamping of an industry that has fallen to neglect. Upon graduation, the sponsored fellows will be contractually required to complete nuclear-related employment at the rate of six months per year of NCSU–GFINE sponsorship. The support of industry for the Department and its mission, and their interest in NCSU–GFINE is evidenced by hiring of our graduates.

Develop Educational program in VVUQ - Multiphysica

Sponsor: US Dept. of Energy (DOE)

Start Date: 11/29/18

End Date: 12/31/20

Abstract

The work performed under this subcontract by Drs. Maria Avramova and Kostadin Ivanov will support the development of educational program in Verification, Validation and Uncertainty Quantification (VVUQ) of single- and multi-physics modeling and simulation (M&S) tools in nuclear science and engineering applications. EGMPEBV is focused on benchmarking, validation procedures, development of experimental databases and uncertainty propagation. There is a need for a new subtask on educational aspects/training for VVUQ for nuclear applications. The work performed under this subcontract will also supports activities associated with the Expert Group on Multi-Physics Experimental data, Benchmarks and Validation (EGMPEBV) of the Nuclear Energy Agency (NEA) of the Organization for Economic Cooperation and Development (OECD).

Multi-physics Modeling of Fast Spectrum Liquid Fuel MSRs, Consortium for Nuclear Power (CNP) Core Project - 1.

Sponsor: Consortium for Nuclear Power (CNP)

Start Date: 7/01/18

End Date: 6/30/21

Abstract

The project will model Molten Salt Reactor (MSR) transients. The modeling will utilize tightly coupling of the complete form of P1 approximation for neutron transport equation to a Computational Fluid Dynamics (CFD) solver for fast spectrum liquid fuel MSR applications. We believe that this multi-physics modeling approach provides the right level of accuracy and speed (efficiency) to study the safety characteristics of MSRs.

Nuclear Energy Knowledge and Validation Center (NEKVac)

Sponsor: US Dept. of Energy (DOE)

Start Date: 12/19/16

End Date: 9/30/17

Abstract

The Nuclear Energy Knowledge and Validation Center (NEKVaC) is a new initiative by the Department of Energy (DOE) and Idaho National Laboratory to coordinate and focus the resources and expertise that exist with the DOE Complex toward solving issues in the validation of codes used for modern nuclear plant and fuel cycle analysis. In time, code owners, users, and developers will view the Center as a partner and essential resource for acquiring the best practices and latest techniques for validating codes, for guidance in planning and executing experiments, for facilitating access to, and maximizing the usefulness of, existing data, and for preserving knowledge for continual use by nuclear professionals and organizations for their own validation needs. The scope of the Center covers many inter related activities, which will need to be cultivated carefully in the near term and managed properly once the Center is fully functional.
