The U.S. Nuclear Regulatory Commission (NRC) is proud to be ranked among the best places to work for compensation, work-life balance, and performance for mid-sized agencies in the Federal Government. We've earned our top ratings by creating a work environment rich in opportunity, diversity, leadership training, teamwork, and work life balance. Help guide our nation into the next generation of nuclear safety! Begin a challenging career with the U.S. Nuclear Regulatory Commission where you can be part of a select group of professionals who protect people and the environment with the peaceful use of nuclear materials in medicine, industry, and research.


This position is located in the Office of Nuclear Regulatory Research (RES), Division of Systems Analysis (DSA), Fuel and Source Term Code Development Branch (FSCB). Headquarters, Rockville, MD.

A Reactor Systems Engineer (Neutronics and Fuel Analyst), conducts and coordinates specialized research and analysis in the area of neutronics and fuel.
Work involves expert use and development of neutronics and fuel codes to support resolution of relevant safety and technical issues of Agency interest. You will provide coordination, planning, development, and technical direction of relevant safety research programs and develop and implement strategies to ensure that neutronics and fuel analytical codes continue to provide capabilities to make safety determinations of new and advanced technologies proposed by the nuclear industry.

Duties include but are not limited to:

1. Performs independent (including in-house) studies of detailed neutronics and fuel analysis using state-of-practice neutronics and fuel computer codes.
2. Maintains and develops the NRC neutronics codes, such as SCALE and PARCS, and fuel performance code such as FAST to meet emerging needs introduced by small modular reactors, micro-reactors, and non-LWR advanced reactor designs.
3. Performs fuel behavior analysis with fuel such as FAST and neutronics codes such as SCALE/Polaris, TRACE-PARCS or other NRC fuel and neutronics codes in support of Agency research needs as well as urgent licensing needs of user offices.
4. Provides technical direction to contractors involved in various neutronics and fuel research and codes development and analysis, and coordinates support to users of these programs.
5. Provides technical review of available experimental data and analytical efforts, and integrates program results with code development needs, interfaces with user offices and assures timely dissemination of results to user offices.
6. Prepares presentations at technical and programmatic review meetings.


In order to qualify for this position, you must have at least one year of specialized experience at the next lower grade level (13) in the Federal service or equivalent experience in the private or public sector.
SPECIALIZED EXPERIENCE is defined as experience that demonstrates knowledge of neutronics and fuel behavior analysis of operating, new and advanced reactor designs.
A description of how you possess the specialized experience should be addressed in your resume, responses to the vacancy questions, and in the additional space provided for your supplemental response.


Qualification for All Professional Engineering 0800 Series:
Basic Requirements:
A. Degree: Engineering. To be acceptable, the program must: (1) lead to a bachelor’s degree in a school of engineering with at least one program accredited by ABET; or (2) include differential and integral calculus and courses (more advanced than first-year physics and chemistry) in five of the following seven areas of engineering science or physics: (a) statics, dynamics; (b) strength of materials (stress-strain relationships); (c) fluid mechanics, hydraulics; (d) thermodynamics; (e) electrical fields and circuits; (f) nature and properties of materials (relating particle and aggregate structure to properties); and (g) any other comparable area of fundamental engineering science or physics, such as optics, heat transfer, soil mechanics, or electronics.
B. Combination of education and experience -- college-level education, training, and/or technical experience that furnished (1) a thorough knowledge of the physical and mathematical sciences underlying engineering, and (2) a good understanding, both theoretical and practical, of the engineering sciences and techniques and their applications to one of the branches of engineering. The adequacy of such background must be demonstrated by one of the following:
1. Professional registration or licensure -- Current registration as an Engineer Intern (EI), Engineer in Training (EIT)1, or licensure as a Professional Engineer (PE) by any State, the District of Columbia, Guam, or Puerto Rico. Absent other means of qualifying under this standard, those applicants who achieved such registration by means other than written test (e.g., State grandfather or eminence provisions) are eligible only for positions that are within or closely related to the specialty field of their registration. For example, an applicant who attains registration through a State Board's eminence provision as a manufacturing engineer typically would be rated eligible only for manufacturing engineering positions.
2. Written Test -- Evidence of having successfully passed the Fundamentals of Engineering (FE)2 examination or any other written test required for professional registration by an engineering licensure board in the various States, the District of Columbia, Guam, and Puerto Rico.
3. Specified academic courses -- Successful completion of at least 60 semester hours of courses in the physical, mathematical, and engineering sciences and that included the courses specified in the basic requirements under paragraph A. The courses must be fully acceptable toward meeting the requirements of an engineering program as described in paragraph A.
4. Related curriculum -- Successful completion of a curriculum leading to a bachelor's degree in an appropriate scientific field, e.g., engineering technology, physics, chemistry, architecture, computer science, mathematics, hydrology, or geology, may be accepted in lieu of a bachelor’s degree in engineering, provided the applicant has had at least 1 year of professional engineering experience acquired under professional engineering supervision and guidance. Ordinarily there should be either an established plan of intensive training to develop professional engineering competence, or several years of prior professional engineering-type experience, e.g., in interdisciplinary positions. (The above examples of related curricula are not all-inclusive.)
