The following information was provided by Curtiss-Wright Nuclear Division via fax:

"On March 16, 2016, Curtiss-Wright was notified by one of our commercial suppliers that they had received an Important Product Safety Notice (safety notice) from Emerson Valve Automation/Hytork concerning Hytork models XL 1371 and XL 1126 pneumatic rack and pinion actuators, manufactured after 2005 and before June 2015.

Curtiss-Wright began evaluating any possible impact at that time. On May 11, 2016 Curtiss-Wright made the decision that the defect was reportable under 10 CFR Part 21. A total of four (4) Hytork XL 1126 pneumatic actuators had been dedicated by Curtiss-Wright and provided as safety-related. Two (2) of the actuators were supplied to the PSEG, Salem Generating Station and the other two (2) were supplied to MOX Services. Both Salem Generating Station and MOX Services have been notified of this potential defect. Curtiss-Wright has not supplied any of the XL 1371 actuators.

"Emerson Valve Automation/Hytork states that there is a small possibility that a crack may develop.Jn the actuator body under normal operation. The Emerson/Hytork investigation determined that a combination of actuator body structural design and material specifications along with manufacturer processes, could lead to material properties that are not within stated specifications. This condition may cause higher than allowable stresses to occur in the actuator body, which could lead to crack initiation. If a crack does develop and the actuator continues to operate, the crack may propagate to the end of the body and the end caps could be forcefully ejected. In addition to operational concerns, this condition may present a personnel safety hazard. *

"Based on phone conversations with Hytork it was learned.that only one model XL 1126 actuator failure has been reported out of approximately 10,000 supplied. Hytork stated that the failed actuator was in a 'severe'

0511312016 U.S. Nuclear Regulatory Commission Operations Center Event Report Page 2 (mechanical, operational) application with very high cycle frequency and likely experienced high impact loading.

"The list below identifies the affected customers, approximate ship dates, applicable purchase orders and actuator details.

PSEG/Salem, approximate date of shipment November, 2011, Customer PO Number 4500606542, Affected Equipment One Hytork EIA-XL 1126-S80AHO Actuator Damper Tag 1CAA14 MOX, approximate date of shipment June, 2014, Customer PO Number 10888-P-6374, Affected Equipment Two Hytork XL 1126SR80 Actuators Catalog ID 14306 (HDE*AOD 01428) & Catalog ID 14309 (HDE*AOD 01978)

PSEG/Salem, approximate date of shipment September 2015, Customer PO Number 4500826720, Affected Equipment One Hytork EIA-XL 1126-S80-AOO Actuator Damper Tag 2CAA 14 "Hytork ceased production of the XL 1126 and XL 1371 actuators in June 2015 due to the described problem.

Hytork is revising the design to connect the defect and will issue new model numbers for the re-designed actuators.

"Hytork expects to begin production of the new models in June of this year. Although Curtiss-Wright has successfully seismically tested two Hytork model XL 1126 actuators under load, providing reasonable assurance that the actuators will survive and operate under normal and seismic loading, it is still recommended that the actuators be replaced as soon as practical. In the interim it is recommended that operating plants perform periodic (recommend weekly or if infrequently operated, following each operation) visual and/or soap-bubble inspections.

The recommended actions provided below are considered to provide adequate indication of onset of this potential condition since instantaneous failures have not been identified and are not projected.

a) For all persons who are or could be in the area where the affected equipment is present, ensure they are warned of the potential danger.

b) Visually inspect all affected models for cracks, especially underneath the dual stroke adjustment pad and on top of the actuator body in the pinion area.

c) If you are unsure whether a crack is present, perform a soap bubble test.

d) If you identify a crack or leak, immediately remove this actuator from service.
