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 opera ting and support organizations appropriate for the safe and efficient operation of nuclear power plants; however requirements for security forces are specified in American National Standard Industrial Security for Nuclear Power Plants, N1B.17-1973 (ANS-3.3). Test, mobile, and research reactors as well as reactors not subject to Nuclear Regulatory Commission (NRC) 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 owner organization. The NRC and other regulatory agencies promulgate regulations applying to many aspects of the design, construction, and operation of nuclear power reactors. This standard shall not take precedence over any such regulation.
