Requirements

A high school diploma or have passed a high school examination equivalency.
Total power plant experience must be greater than 18 months for a nuclear or
military reactor facility, or greater than 27 months for a non-nuclear facility.
The candidate must meet one of the criteria below:
A.) Candidate has at least 6 months of experience performing plant operational duties as a qualified non-licensed operator at the Callaway Nuclear facility.
B.) Candidate has at least 12 months experience performing plant operational duties as a qualified non-licensed operator at a comparable (BWR/PWR) nuclear facility or 18 months of experience at a noncomparable commercial power reactor facility.
C.) Candidate have at least 6 months of experience performing plant operational duties as an active licensed reactor operator (per 10 CFR 55.53[e]) at a comparable (BWR/PWR) nuclear facility or 12 months of experience at a noncomparable commercial power reactor facility.
D.) Candidate has at least 18 months of experience in a position equivalent to the reactor operator position at a military reactor? This includes reactor operators, engineering officer of the watch, propulsion plant watch officer, engineering watch supervisor, and propulsion plant watch supervisor.
E.) Candidate has 27 months power plant experience at a non-nuclear facility (power plant experience is defined in the additional action section).
Must have good eyesight, good reflexes, good hearing and no color
deficiency in vision.
The candidate must successfully complete a full medical examination.
This medical examination is to include a test or examination by a
psychiatrist or physician to determine that there is no sign of aberrant
behavior or emotional instability that would impair ability to discharge
duties in a competent manner
Power Plant experience is defined as applicable work performed in fossil fueled or nuclear-fueled electric power production plants during preoperational, startup testing or operational activities. Experience in petrochemical; similar process plants; or steam propulsion plant design, construction, technical support, operation, maintenance, or training instruction can be substituted for applicable power plant experience. Simply observing others performing work is not considered power plant experience. Time spent in classroom training cannot be counted toward power plant experience requirements. However, time spent performing job-based training and qualification activities in the plant — such as under instruction watch standing, on-the-job training, and task or watch station qualification activities — can be applied toward power plant experience requirements. Time spent performing in-plant job-based training and qualification activities should be specifically documented if such time is used to meet power plant experience requirements.
