GRADUATE EDUCATION: In the absence of specific graduate program information, a year of graduate education is 18 semester hours or 27 quarter hours of graduate level college course work, or the number of credit hours the school attended has determined to represent 1 year of full time study. This education must have been obtained in an accredited college or university.

BASIC EDUCATION REQUIREMENT: Applicants must meet A or B below to satisfy the basic education requirement for Nuclear Engineer, all grade levels.

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.

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.

Examples of such experience may include managing complex technical operations of a nuclear facility, providing significant and innovative recommendations for the design, construction, test, evaluation, troubleshooting, repairing, and maintenance of a nuclear reactor that has equipped you with the knowledge, skills and abilities to perform successfully the duties of this position.

You must meet all qualification and eligibility requirements for the position by the closing date of the announcement.

Conditions of Employment for this Position:

As a condition of employment for accepting this position, you may be required to serve a 1-year probation period during which your fitness and whether your continued employment advances the public interest will be evaluated.

In determining if your employment advances the public interest, the agency will consider:

- your performance and conduct;
- the needs and interests of the agency;
- whether your continued employment would advance organizational goals of the agency or the Government; and
- whether your continued employment would advance the efficiency of the Federal service.

Under applicable law, the employment of an individual serving a probationary or trial period automatically terminates when that period ends unless the agency affirmatively certifies, in writing, that the individual's employment should continue and that their appointment should be finalized. In the absence of agency action to affirmatively certify continued employment beyond the probationary or trial period, such appointments are terminated.

Upon completion of your probation period your employment will be terminated unless you receive certification, in writing, that your continued employment advances the public interest.

You will receive credit for all qualifying experience, including volunteer experience.
