B.S. Electrical Engineering, George Washington University Summary:
Mr. Nguyen has 22 years of experience in the nuclear power industry regulation including pressurized water reactors (PWRs) as well as boiling water reactors (BWRs). He has acquired extensive knowledge and experience in electrical engineering, instrumentation and controls, operations, inspection, maintenance, and licensing and regulation of the nuclear industry. Mr.
Nguyen has reviewed and evaluated electric power system and instrumentation and control designs to regulatory requirements. He identified areas of non-compliance to regulatory requirements, prepared requests for additional information and authored safety evaluation reports including station license amendment related to alternate source term, technical specification changes regarding shutdown operation involving positive reactivity additions, standard technical specification conversion, emergency technical specification amendment regarding allowed outage time extension for emergency diesel generator, etc. He performed independent engineering analysis to verify the adequacy of licensee=s design. An example was his evaluation of a license amendment request regarding offsite power instrumentation and voltage controls design change. He worked extensively on onsite and offsite electrical power systems for PWRs and BWRs including normal and emergency power technical specification review. During his 22 years at the NRC, Mr. Nguyen has managed various projects and accomplished tasks within budget and ahead of schedule. He has performed in various capacities such as technical monitor for contracts, inspector, and as a technical expert in the areas of license renewal. He conducted reviews and authored safety evaluations, information notices, developed interim staff guidance and other generic communications. Mr. Nguyen conducted over twenty four license renewal audits, and participated in electrical distribution system functional inspections, and system based instrumentation and control inspections. He is knowledgeable in the areas of power distribution systems and the operation and safety functions associated with reactor protection systems and engineered safety features. He is experienced in evaluating instrumentation setpoints, protective relay setpoints, environmental qualification of electric equipment, and onsite and offsite power distribution systems.
Throughout his professional career, he applied engineering-related theories, principles, particularly with respect to design, operation, licensing, and regulation of nuclear power plants.

U.S. Nuclear Regulatory Commission, 1990-Present 2006 - Present Aging Management of Structures, Electrical, and Systems Branch, Division of License Renewal, Office of Nuclear Reactor Regulation Conducted safety review audits consisting of numerous technical reviews including preparing audit reports, and the safety evaluation inputs for the license renewal applications submitted for Farley, Brunswick, Palisades, Vermont Yankee, Pilgrims, Fitzpatrick, Wolf Creek, Indian Point, Three Mile Island, Beaver Valley, Susquehanna, Cooper, Duane Arnold, Kewaunee, Palo Verde, Prairie Island, Salem, Hope Creek, Crystal River, Diablo Canyon, Seabrook, Davis-Besse, South Texas, Limerick, and Grand Gulf. Participated in the staffs presentations at the Advisory Committee on Reactor Safeguards (ACRS) subcommittee and full committee on license renewal applications. Developed interim staff guidance on certain aging management programs including ISG 2007-02, Change to GALL AMP XI.E6, Electrical Cable Connections Not Subject to Environmental Qualification Requirements.
Assisted in the update of the 2010 version of NUREG-1801, Revision 2 (Generic Aging Lesson Learned (GALL) Volume 2, Revision 2), as related to aging management reviews (AMRs), aging management programs (AMPs), and time limiting aging analysis (TLAA) for the electrical and instrumentation and control systems. Also updated the Standard Review Plan (SRP) corresponding sections for these AMRs, AMPs, and TLAA (NUREG-1800, Revision 2).
1993-2006 Electrical Engineering Branch, Division of Engineering, Office of Nuclear Reactor Regulation Conducted safety reviews and preparing safety evaluation inputs for license renewal applications submitted by the applicants for Calvert Cliff, Arkansas Nuclear One (ANO-1), Oconee, McGuire and Catawba, Turkey Point, St. Lucie, and V.C. Summer.
Assisted in the updated of the 2005 version of GALL Revision 1, as related to AMRs, AMPs, and TLLA for electrical and I&C systems. Also updated SRP corresponding sections for these AMPs, AMRs, and TLAA (NUREG-1800, Revision 1).
Managed Brookhaven National Lab (BNL) contract (JCN J-2831) entitled Aging Management of Safety-Related Fuses Used in Low-and Medium Voltage Application in Nuclear Power Plants. Responsibility included development of statement of work (SOW), monitoring performance of contract including cost expenditures, timeliness in meeting schedule milestone, and technical adequacy and quality of deliverables. Issued NUREG-1760 and developed interim staff guidance on fuse holders for license renewal based on recommendations of NUREG-1760.
Performed evaluations supporting safety evaluation reports for license amendment reviews. These reviews included emergency diesel generators (EDGs), license amendment for power uprates, technical specifications of electrical power systems, 125 Vdc vital instrumentation and control power systems, under voltage protection, extended power uprate (EPU), Class 1E 250 Vdc battery load profiles, on line testing of EDGs, battery surveillance requirements, inverter extended allowed outage time, alternate source term technical specifications, setpoint of offsite power instrumentation and voltage controls..
Conducted safety reviews and provided safety evaluation input for the Department of Energys (DOEs) tritium product core (TPC) topical report.
This topical report addressed the safety and licensing issues associated with incorporating a full complement of tritium producing burnable absorber rods in a representative commercial light water reactor.
Efforts resulted in the issuance of NUREG-1672, Safety Evaluation Report Related to The Department of Energys Topical Report on The Tritium Production Core, in May, 1999.
Developed an action plan for resolving charging/discharging issues involving flooded lead acid batteries. The purpose of this action plan was to investigate a potential generic issue related to the ability of safety-related batteries at nuclear power plants to power their intended function when the battery has been recharged after a discharge. The action plan discussed the scope, included major milestone and proposed schedule for completion of each milestone, estimated the staff full time employment and contractor dollars needed to complete of the action plan.
Performed a study on the effect of test equipment harmonic distortion on under-voltage relay functionality. The settings of under-voltage protection relays were out of calibration due to test equipment harmonic distortion. Issued Information Notice (IN) 95-05 that clearly defined the problem and solutions.
Issued IN 97-45 and IN 97-45 Supplement 1 entitled, Environmental Qualification Deficiency for Cables and Containment Penetration Pigtails. The IN was issued to alert licensees of erratic indication of high range radiation monitors as a result of a problem with their coaxial cables. High temperature in the containment could produce a temperature-induced signal that could result in erratic indication of high range radiation monitors.
