Clarification from the agency

All NRC Employees are encouraged to apply.

Duties

Help

The successful candidate will perform the full range of Nuclear Engineer duties.

Such duties include but are not limited to:

1.  Performing complex reviews and evaluations of design, process design parameters, and performance of reactor thermal-hydraulic systems for operating reactor designs and for new reactor designs, with an emphasis on improving the knowledge of key safety and risk aspects related to reactor licensing activities.

2.  Performing complex reviews and evaluations of nuclear and thermal-hydraulic aspects of the reactor core under steady-state, transient, and accident conditions, including issues pertaining to core physics, fuel behavior, and reactivity control system and control rod design.

3.  May perform reactor systems analyses using advanced computer simulation for licensing review, including independent calculations and engineering analyses to confirm or verify the applicants' or licensees' predictions of systems and component performance, including fuel and core performance, under postulated transient and accident conditions.

4.  Supporting the project leader in the resolution of highly complex technical problems such as emergency core cooling systems performance, containment systems performance, balance of plant systems performance, equipment qualification, uncertainty qualification, and verification and validation of methods.

5.  In performing design certification, combined license, license amendment or topical report reviews, coordinates with other review branches as may be needed to draft questions and positions or request  meetings with the applicant, licensee, or vendor through the Project Manager to obtain additional or clarifying information, and to resolve inconsistencies in interpretation of safety criteria.

Conditions of employment

  • This is a Drug Testing position.
  • Must be able to meet/maintain security & suitability requirements.

You must meet the qualifications for this position by no later than 30 calendar days after the closing date of this announcement and before placement in the position.

All information in your resume must be true and accurate.

Qualifications

In order to qualify for this position, you must have at least one year of specialized experience at the next lower grade level in the Federal service or equivalent experience in the private or public sector.

SPECIALIZED EXPERIENCE is defined as:  experience technically and analytically reviewing and evaluating design, process design parameters, and performance of reactor systems and nuclear fuel designs for nuclear reactors, including both thermal hydraulic and reactivity phenomena under steady-state, transient and accident conditions for design basis events.

A description of how you possess the specialized experience as well as how you meet the qualifications desired in an ideal candidate should be addressed in your resume.

The ideal candidate will be able to demonstrate the following:

1. Demonstrated knowledge of capacity to apply the theories, principles, and practices in the field of reactor core, fuel and thermal-hydraulic systems design and nuclear methods sufficient to perform complex reviews and evaluations of nuclear and thermal-hydraulic aspects of the reactor core under steady-state, transient, and accident conditions, including issues pertaining to core physics, fuel behavior, and reactivity control system and control rod design for operating or new light-water or non-light-water power or non-power reactor or nuclear fuel designs.
Describe specific experience, education, and training that demonstrate your ability to apply your knowledge related to reactor core, fuel and thermal-hydraulic systems design and nuclear methods for operating or new light-water or non-light-water power or non-power reactors or nuclear fuel designs. Include examples relative to both thermal hydraulic and reactivity phenomena under steady-state, transient and accident conditions for licensing basis events and issues related to qualification of nuclear fuel designs. Highlight experience in performing computer-assisted analyses in the area of nuclear fuel, reactor thermal-hydraulics and/or core physics for licensing basis event analysis.

2. Demonstrated ability in formulating sound technical judgements, making technical or policy recommendations, and finding solutions to unique first of a kind technical or policy challenges regarding issues pertaining to event evaluation in the areas of core physics, fuel behavior, reactivity control system and control rod design, and core thermal-hydraulic performance.

Describe education, training and experience that demonstrate your ability to formulate technical judgments. Provide examples of judgments, recommendations, or actions you have taken regarding unique first of a kind technical or policy issues pertaining to core physics, fuel behavior, reactivity control system and core thermal-hydraulic performance. Describe your ability to identify complex issues and recommend successful approaches for resolution for areas representing a departure from past precedent, or in the absence of applicable guidance. Highlight examples that demonstrate resourcefulness, initiative, and ingenuity in reaching work objectives. Include specific examples that describe the complexity of the work, and your ability to organize, prioritize and accomplish work such as reactor systems reviews, or authorship of technical or policy papers.

3. Demonstrated knowledge of NRC rules, regulations, and policies pertaining to light-water or non-light-water power or non-power production or utilization facilities through familiarity with NRC’s advanced reactor vison, strategy, and policy activities, reactor licensing regulations, passive reactor design policies, system design standards, and regulatory guides and practices.

Describe specific experience, training, and accomplishments that demonstrate your familiarity with NRC rules, regulations, and policies pertaining to light-water and non-light-water power or non-power production or utilization facilities. Include several technical work examples and describe the complexity of the issues.

4.  Demonstrated ability to communicate information, ideas, and advice in a clear, concise, and logical manner, both orally and in writing. Demonstrated ability to establish and maintain effective work relationships with management and staff, colleagues, and representatives of external organizations.

Describe education, training, and experience which demonstrate your ability to present information, ideas, and advice in a clear, concise, and logical manner both orally and in writing. Describe your ability to deal effectively with various levels of staff, to coordinate and prepare documents using various inputs. Describe the various types and levels of individuals you routinely interact with and for what purposes. What types of original writing do you generate? With whom do you communicate orally and for what purpose? What types of working relationships have you made, with whom, and how frequently? Include examples of situations where it was necessary for you to use tact, diplomacy, and negotiation skills to achieve cooperation or consensus when interacting with staff, management, or the general public.

PLEASE BE CLEAR AND SPECIFIC. WE WILL NOT MAKE ASSUMPTIONS REGARDING YOUR EXPERIENCE.

Education

Basic Requirement for 0801 Series:

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.

OR

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.
