F-A, Item F1 .20C setting found out of range . The condition was evaluated in accordance Acceptance range is 2078 with IWF-3122.3. Since the spring support was lbs, +/- 54 (2024 lbs to determined to still be able to perform its design 2132 lbs). As-found function , corrective measures were performed setting 2350 lbs. [NOi to restore the support to its orig ina l design U1R12-001) condition per IWF-3122.3 (b). WO 11 9973691 reset the load setting of the spring to the design range specifications. Therefore, no add itional or preservice exams are applicable. The spring support was then reinspected to ve rify th e settings.
E-A, Item E1 .11 Gouge in Drywell liner. EVALUATED ACCEPTABLE
[NOi U1 R12-002] (No Corrective Measures Requ ired .)
An indication cons isting of mechanical damage 1/32" in depth , 3/8" in width , and 7/16" in length was identified on the steel conta inment vessel (Drywell) liner. The remaining wall th ickness was 0.73" in the area of mechanica l damage.
The wall thickness was below the acceptance criteria without Civil Design Eng ineeri ng evaluation of 0.75". Civil Engineering determined that the remaining th ickness of 0.73" is greater than the allowed 10% reduction of wall thickness (0.675"), thus it is acceptable for continued operation . Per IWE-3122.3 (b) the area will be reexamined in accordance with IWE-2420.

None of the areas penetrated the full MSB-1-1 [NOi U1R12- depth of the seal , seal adhesion was 003] good in all locations, and there was no seal failure . The affected portions of the seal identified for repair were excavated and drywell liner below the seal was VT-1 examined . No evidence of moisture intrusion or damage to the liner indicative of moisture intrusion was observed demonstrating no seal failure occurred . The MSB was then re-poured in these areas and re-examined .
