update, regardless of whether the activity is the result of the RI-ISI program examination. Evaluating this information as it relates to a licensee’s plant provides failure information and trending information that may have a profound effect on the element locations currently being examined under the RI-ISI program. Industry failure data are just as RG 1.178, Page 21 important to the overall program as the owner’s information. During the periodic update, industry data bases (including available international data bases) should be reviewed for applicability to the owner’s plant. 3.3 Corrective Action Programs Each licensee of a nuclear power plant is responsible for having a corrective action program, consistent with RG 1.174. Measures are to be established to ensure that conditions adverse to quality, such as failures, malfunctions, deficiencies, deviations, defective material and equipment, and nonconformances, are promptly identified and corrected. In the case of significant conditions adverse to quality, the measures must ensure that the cause of the condition is determined and corrective action is taken to preclude repetition. The identification of the significant condition adverse to quality, the cause of the condition, and the corrective action are to be documented and reported to appropriate levels of management. For ASME BPV Code piping categorized as safety significant, this corrective action program should be consistent with applicable provisions in ASME BPV Code, Section XI. For non-Code and Code-exempt piping categorized as safety significant, the licensee should also use appropriate Section XI provisions or should submit an alternative program based on the risk significance of the piping. 3.4 Acceptance Guidelines The following acceptance guidelines are for the implementation, monitoring, and corrective action programs for the accepted RI-ISI program plan: a. The evaluation of the implementation program will be based on the attributes presented
