REQUEST FOR ADDITIONAL INFORMATION OCONEE NUCLEAR STATION. UNITS 1. 2. AND 3 LICENSE RENEWAL APPLICATION, EXHIBIT A OLRP-1001 Section No.
3.7.4 Earthen Embankments 3.7.4-1 Section 3.7.4.1 lists the following applicable aging effects (1) loss of material due to erosion, (2) cracking due to settlement or frost heave, and (3) change in material properties due to desiccation. Aging effects (1) and (2) are discussed in sections 3.7.4.1.1 and 3.7.4.1.2, respectively, however, effect (3) is not mentioned further within Section 3.7.4. Provide a discussion of the applicability this aging effect.
4.15 Federal Energy Regulatory Commission (FERC) 5-Year Inspection 4.15-1 The method used to detect possible aging effects, such as loss of material due to erosion and seepage, leakage, internal stress and hydrostatic pressure, is described as "visual examination of external surfaces." Is the method used to detect these potential aging effects entirely visual or are there parameters such as hydraulic head and uplift pressure that are monitored?
4.15-2 The acceptance criteria for the FERC Inspection Program is based on "the knowledge of the qualified independent consultant." Elaborate on the criteria used by the inspector to determine if aging effects, such as loss of material, internal stress, and hydrostatic pressure, are within acceptable limits. Are there quantitative values for some of these aging effects that are monitored more frequently than once every 5 years?
4.15-3 For each of the identified aging effects, describe the actions that would be taken if the acceptance criteria were not met.
4.15-4 Past 5-year inspections of the earthen embankments have detected only minor seepage, saturation, and erosion with the conclusion that, "The general appearance and condition of the earthen structures remains acceptable though (sic) all inspections." Provide more information regarding the evidence that lead inspectors to the above conclusion. Is this conclusion entirely qualitative?
