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.

The following is a synopsis of a letter received from Flowserve:

On 09/06/19, Flowserve issued its Final Report for the Part 21, noting the scope of the valves/components affected by the issue described above. Flowserve also noted the corrective actions that were taken to address the issue and detailed the specific actions taken for the individual components.

Notified R1DO (Carfang), R2DO (Shaeffer), R3DO(Edwards), R4DO(O'Keefe), and Part 21/50.55 Reactors Group (e-mail).

CONTAINMENT PENETRATION DISCOVERED NOT ISOLATED

"At 2115 CDT on 9/5/2019, an inside containment test connection and inoperable outside containment isolation valve were discovered to be open for a containment air sample penetration. This resulted in the containment penetration not being isolated. The inside containment test connection was closed at 2322 CDT on 9/5/2019.

"This event is being reported under 10 CFR 50.72(b)(3)(v)(C) and (D) and 10 CFR 50.72(b)(3)(ii)(B).

"There was no impact to the health and safety of the public or plant personnel. The NRC Resident Inspector has been notified. "

AUTOMATIC REACTOR TRIP

"On September 09, 2019 at 0824 EDT, with St. Lucie Unit 1 in Mode 1 at 100 percent power, the reactor automatically tripped on Low Reactor Coolant System Flow due to a trip of the 1A1 reactor coolant pump. The trip was uncomplicated with all systems responding normally post-trip. Operators responded and stabilized the plant in Mode 3. The cause of the loss of the 1A1 reactor coolant pump is currently under investigation.

"St. Lucie Unit 2 was unaffected and remains in Mode 1 at 100 percent power.

"This report is submitted in accordance with 10 CFR 50.72(b)(2)(iv)(B) for the reactor trip."

Decay heat removal is being accomplished by main feed water and the main condenser using the turbine steam bypass valves.

The licensee notified the NRC Resident Inspector.

AUTOMATIC REACTOR TRIP

"At 1309 EDT on September 7, 2019, with the unit in Mode 1 at approximately 95 percent power, the reactor automatically tripped during main turbine valve testing. The trip was not complex with all systems responding normally post-trip.

"Operations responded and stabilized the plant. Decay heat is being removed by the turbine bypass valves discharging steam to the main condenser.

"Due to the reactor protection system actuation while critical, this event is being reported as a four-hour, non-emergency notification per 10 CFR 50.72(b)(2)(iv)(B). The cause of the reactor protection system actuation is under evaluation.

"There was no impact on the health and safety of the public or plant personnel. The NRC Resident Inspector has been notified."
