|PART 21 - NON-DESTRUCTIVE EXAMINATION PERFORMANCE OF COMPONENTS BY AN UNQUALIFIED EMPLOYEE
The following is a summary of the information received from Flowserve via facsimile:
Contrary to the requirements of ASME Section III & ASME NQA-1 Requirement 2, an employee of Flowserve was found to have performed Non-Destructive Examinations (Liquid Penetrant Testing - PTs) without the required certificate in accordance with ASNT SNT-TC-1A, and Flowserve's written practice. The employee was trained and tested in accordance with the written practice and ASNT requirements. Although the individual section scores were found to pass the (70 percent) minimum, the composite test requirements failed to meet the minimum 80 percent requirement. Actual composite score achieved was 79.176 percent.
The extent of exposure to this condition was on examinations completed between 10/22/18 and 11/21/18. There were ten examinations, totaling 22 pieces that were completed by the employee without oversight/signature by another certified individual.
The scope of impacted valves/components encompasses body, stem, cover, yoke, pin wedge, and disk. Licensees affected include Exelon Company, Pinnacle West Capital Corp, Bruce Power, Xcel Energy, Alabama Power, Entergy Nuclear Operations Inc., and FirstEnergy.
Flowserve issues a corrective action, and is currently in the process of determining the root cause and prevention action measures. This will include identifying the affected valves via communications with affected customers.
