AMPP Nuclear Coatings case studies
AMPP Nuclear Coatings · Put your knowledge to work in context.
The AMPP Nuclear Coatings Inspector credential is a professional certification for coatings personnel who work in nuclear power and nuclear fuel cycle facilities, where protective coating systems must perform reliably under radiation exposure, contamination-control requirements, and rigorous quality-assurance regimes. It is aimed at coating inspectors, quality control and quality assurance personnel, coatings applicators and supervisors, and utility or owner staff who verify that protective coating work in nuclear service meets specification and design-intent requirements. The AMPP Nuclear Coatings case studies are 5 cases and about 1,996 words.
1Substituting a Discontinued Containment Spray-Zone Topcoat
During a refueling outage, a BWR containment spray-zone coating must be repaired. The original Service Level I epoxy topcoat is discontinued.

An underground radioactive waste transfer room has 120 m² of concrete wall coating with 30% blistering and peeling. The specification requires 'abrasive blast to SSPC-SP 10' and a chloride limit of 5 µg/cm².
410 words, about 2 min3Second-Coat Application Outside Environmental Limits
At 06:00, the applicator begins the second coat of a Service Level II epoxy in a containment access corridor. Readings: air temperature 58°F, relative humidity 90%, steel substrate 57°F, dew point 56°F.

An inspector surveys 200 m² of epoxy floor coating specified at 12–16 mils DFT. The magnetic gauge was calibrated at the start of the shift on a certified shim.
382 words, about 2 min5Bypassed Hold Point and Ambient Logging Gap
During final QA review of a safety-related coating package, the inspector finds that the stripe coat hold point was signed by the applicator's foreman, not the QC inspector. The final DFT and holiday test records are complete and acceptable.
