D. C. Cook Nuclear Unit 2 Table 1 Items with Flaws or Relevant Conditions That Required Evaluation for Continued Service Examination Category and Item Number Item Description Evaluation Description Relevant conditions including boric acid deposits, discoloration and entrained residues were identified at 2 penetrations of the Reactor Vessel Closure Head (RVCH) during Visual Examination (VE). After cleaning, no relevant conditions and no degradation of the RVCH was identified during the as-left VE. The relevant conditions were attributed to leakage from in-core instrumentation (ICI)
N-729-6 B4.40 Nozzles and partial-penetration welds of PWSCC-thermocouple sealing assemblies (TECSA) and were not resistant materials in head indicative of possible nozzle leakage. Relief was granted from performing the supplemental UT and surface examinations required under ASME Code Case N-729-6 (ADAMS Accession Number ML22363A562).
