CASE N-532-5 Page 1 of 2 TABLE 1 ITEMS WITH FLAWS OR RELEVANT CONDITIONS THAT REQUIRED EVALUATION FOR CONTINUED SERVICE Examination Category and Item Number Item Description Evaluation Description B-P, B15.10 Boric acid residue found during the performance of the ASME Section XI required VT-2 visual examinations associated with the Class A Bolted Connections in Upper Containment was performed per work order 20543582. During the examination, the following as found boric acid leakage conditions were identified on valves 2NC-31B, 2NC-35B, 2NC-53-FL1, and 2NC-53-FL2.
Relevant conditions identified in NCR 02462292 were evaluated by Engineering and found to be acceptable.
B-P, B15.10 Boric acid residue found during the performance of the ASME Section XI required VT-2 visual examinations associated with the ISI Class A Leakage Test evidence of leakage was identified on the following components: 2B, C, and D's Reactor Coolant Pump (2NCPU0002, 2NCPU0003, 2NCPU0004 respectively).
Relevant conditions identified in NCR 02467441 were evaluated by Engineering and found to be acceptable.
B-P, B15.10 Boric acid residue found during the performance of the ASME Section XI required VT-2 visual examinations associated with the ISI Class A Leakage Test evidence of leakage was identified on the following RX Seal Table locations: B-6, H-2, B-8, D-8.
Relevant conditions identified in NCR 02467437were evaluated by Engineering and found to be acceptable.
F-A, F1.20C ISI VT-3 Visual Examination of support 2MCA-SV-H55 was performed and during the examination, the as found cold load setting of 1210# was observed. Design cold load setting is 1068# with +/-
10% range. Previous data was reviewed which had acceptable as found cold load setting.
Relevant condition identified in NCR 02462368 were evaluated by Engineering and found to be acceptable.
Additionally, the cold load setting was reset per the loads and tolerance given by the specification documents.
E-A, E1.30 The Visual Examination of the Primary Containment Moisture Barrier was performed as required by ASME Section XI, Subsection IWE. The examination identified relevant conditions of the moisture barrier such as wear, damage, surface cracks, and lack of adhesion that could permit intrusion of moisture against inaccessible areas of pressure retaining surfaces of the metallic containment shell and insulation panels protecting the metallic shell.
Relevant conditions identified in NCR 02462564 evaluated by Engineering and restored using corrective measures.
E-A, E1.30 ASME Section XI, ISI VT-3 Visual Examination of Primary Containment Leak Chase Channel Enclosures was performed and during the examination, it was identified that leak chase channel enclosure # 69 was missing the bronze closure cover.
Relevant conditions identified in NCR 02462755 evaluated by Engineering to be acceptable for continued service and electively restored.
