Develop Educational program in VVUQ - Multiphysica

Sponsor: US Dept. of Energy (DOE)

Start Date: 11/29/18

End Date: 9/30/19

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: 6/30/19

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.

Faculty Development Program in Nuclear Engineering at North Carolina State University, 2017

Start Date: 6/30/17

End Date: 6/29/20

Abstract

NRC faculty development grants previously awarded to the Department of Nuclear Engineering at North Carolina State University (NCSU) have been extremely beneficial to the development and success of our tenure-track faculty to advance in their academic careers. We hired a new faculty in the area of nuclear materials and we are recruiting and interviewing new entry-level faculty in one of the respective areas of dosimetry and nuclear assay, fission power reactors, thermal hydraulics, and related subjects. The NRC faculty development program will help us supporting the newly hired faculty and the r4ecruiting of new faculty by encouraging recently graduated PhDs of the highest caliber to apply to our program. Upon hiring, and with the NRC award plus what we provide as a startup package, the hired junior faculty will be supported and helped to establish their academic career with the help of the senior faculty mentorship. A measure of the NRC faculty development award will be realized when the tenure-track faculty successfully advances towards tenure and promotion to higher ranks, and earning a reputation within the nuclear engineering institutions. For our department of nuclear engineering, it is a great benefit to hire top talent young faculty in the open positions and to retain recently hired tenure-track faculty with our expansion in all nuclear engineering main thrust research areas.

North Carolina State University’s Graduate Fellowship in Nuclear Engineering (NCSU–GFINE) - 2016

Sponsor: US Nuclear Regulatory Commission

Start Date: 7/01/16

End Date: 6/30/20

Abstract

This proposal is a request for financial support for 2 graduate students 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 commitment by NCSU’s Department of Nuclear Engineering and College of Engineering to the success of NCSU–GFINE is evidenced by a cost-sharing contribution.
