This standard provides criteria for the selection and training of personnel for stationary nuclear power plants. It addresses itself to the qualifications, responsibilities, and training of personnel in operating and support organizations appropriate for the safe and efficient operation of nuclear power plants. Test, mobile, and experimental reactors as well as reactors not subject to Atomic Energy Commission licensing are excluded because of differences in operational practices and contractual requirements. Individual job titles and organizational structures vary among organizations operating power reactors; therefore, this standard is predicated on levels of responsibility rather than on a particular organizational concept. This standard is further limited to personnel within the operating organization who have a direct relationship to technical aspects, operation, or maintenance of the plant. The Atomic Energy Commission (AEC) promulgates regulations applying to many aspects of the design, construction, and operation of nuclear power reactors. This standard shall not take precedence over any AEC regulation.
