, 1.In a 2024 NRC inspection scenario at a pressurized water reactor (PWR) undergoing steam generator
replacement, the coatings inspector identifies nonconformances in the application of epoxy-based
containment liner coatings under 10 CFR 50 Appendix B Criterion XV. The licensee proposes a corrective
action plan involving re-inspection protocols and material segregation.
Which of the following elements must be incorporated into the plan to ensure compliance with Criterion
XVI (Corrective Action), assuming a multi-vendor supply chain with potential 10 CFR 21 reportability
thresholds exceeded due to coating delamination risks affecting structural integrity?
A. Calculation of delamination propagation rate using finite element analysis with parameters σ_yield =
250 MPa and E_modulus = 3.5 GPa for the epoxy matrix
B. Verification steps including ultrasonic thickness measurement at 5 mm grid spacing and adhesion
pull-off testing per ASTM D4541 with minimum 1000 psi acceptance criterion
C. Root cause analysis applying Ishikawa diagram methodology integrated with probabilistic risk
assessment (PRA) models updated per NRC Regulatory Guide 1.200 Revision 2
D. Segregation protocols mandating RFID tagging of nonconforming batches and quarantine storage per
ANSI N45.2.2-1972, with audit trails traceable to procurement documents under Criterion VII
Answer: A, B, C
Explanation:
Under 10 CFR 50 Appendix B Criterion XVI, corrective actions for nonconforming coatings must address
immediate disposition, root cause investigation, and preventive measures to mitigate recurrence,
particularly in safety-related applications like containment liners where delamination could compromise
leak -tightness. The delamination propagation rate calculation using finite element analysis with specified
yield stress and modulus parameters quantifies the safety margin degradation under seismic loads,
aligning with design control under Criterion III. Verification steps such as ultrasonic gridding and adhesion
testing per ASTM D4541 ensure objective evidence of quality restoration, directly supporting inspection
requirements under Criterion X. Root cause analysis via Ishikawa diagrams combined with PRA per RG
1.200 Rev. 2 evaluates broader implications, including potential core damage frequency increases,
fulfilling the criterion's emphasis on systemic improvements. Segregation protocols, while essential for
material control under Criterion VII, do not directly constitute corrective action elements unless tied to
recurrence prevention, which is secondary here.
2.What is the correct formula relating initial contamination Ci, contamination after decontamination Cf,
and Decontamination Factor (DF)?
A. DF=Cf/Ci
B. DF=Ci/Cf
C. DF=Ci×Cf
D. DF=Ci−Cf
Answer: B
Explanation:
The Decontamination Factor is the ratio of initial contamination to final residual contamination, measuring
efficiency of removal.
3.CSL I dry liner weld area, post-quake check under RWP 100 mrem.
Which?
A. VT-1 borescope 12x, weld indication per IWE-3510.3: height <1/64 inch accept.
