[en] The Historical Data Summary of the Systematic Assessment of Licensee Performance (SALP) is produced periodically by the US Nuclear Regulatory Commission. This summary provides the results of the assessment for each facility by NRC region and is further divided into the following sections: Section 1 presents the most recent SALP report ratings for facilities in operation and under construction. Section 1 ratings for reactors in operation is subdivided into two parts. The first part is summary data based on prerevised Manual Chapter 0516 functional areas. The second part is summary data based on the revised Manual Chapter 0516 functional areas. Section 2 presents a chronological listing of all SALP report ratings for each operating facility. Section 2 ratings for reactors in operation is also divided into two parts, with the first part based on the prerevised Manual Chapter 0516 and the second part based on the revised Manual Chapter 0516 functional areas. Section 3 presents a chronological listing of all SALP report ratings for each facility under construction. For historical purposes, past construction ratings for facilities that recently have been licensed also are listed in Section 3
