REQUEST FOR ADDITIONAL INFORMATION BY THE OFFICE OF NUCLEAR REACTOR REGULATION REQUEST FOR A ONE-TIME EXTENSION OF CONTAINMENT INTEGRATED LEAKAGE RATE TEST INTERVAL FACILITY OPERATING LICENSE NO. DPR-46 NEBRASKA PUBLIC POWER DISTRICT COOPER NUCLEAR STATION DOCKET NO. 50-298

1. IWE-1240 requires licensees to identify the containment surface areas requiring augmented examinations. Provide the locations of the steel containment surfaces that have been identified as requiring augmented examination and a summary of the findings of the examinations performed.
2. For the examination of penetration seals and gaskets, and examination and testing of bolted connections associated with the primary containment pressure boundary, the licensee requested relief from the requirements of the code. As an alternative, the licensee proposed to examine the above items during the leak-rate testing of the primary containment. Option B of Appendix J for Type B and Type C testing (per Nuclear Energy Institute (NEI) 94-01 and Regulatory Guide (RG) 1.163), and the integrated leakage rate test extension requested in this amendment for Type A testing, provide flexibility in the scheduling of these inspections. Discuss your schedule for examination and testing of seals, gaskets, and bolted connections that provide assurance regarding the integrity of the containment pressure boundary.
3. Inspections of some steel containment structures have identified degradation of uninspectable areas (gap between the shield wall and drywell). These degradations cannot be found by visual (i.e., VT-1 or VT-3) examinations unless they are through the thickness of the shell or when 100 percent of the uninspectable surfaces are periodically examined by ultrasonic testing. Discuss what approach is used in the Cooper Nuclear Station (CNS) to identify degradation of uninspectable areas of the containment.
4. In response to Generic Letter 87-05, CNS committed to implement new surveillance procedures for inspection of sand cushion drains during refueling outages. Discuss the results obtained from the inspection.
