(ht) Nature of the defect or failure to comply and the safety hazard which Is created or could be created by such defect of failure to comply.

ESI was notified by a nuclear customer of two Instances where a bolt was found loose or backed out of the cover of an EMD engine driven fuel pump PIN 8410219. Following notification, ES/ inspected remaining pumps in inventory and found Instances where one or more the pump cover bolts were loose or lightly torqued. See Figure 1 below for a visual depiction of the pump and bolts.

2of2 EMD fuel pump, PIN 8410219, is commonly used on all 12, 16, and 20-cylinder EMD model B45E4, E4B, and F4B engines. The pump is either mechanically driven from the engine (via the scavenging lube oil pump) or motor driven (as In the case of a backup/redundant fuel pump). The pump transfers fuel ail from the day tank to the fuel injectors to support fuel combustion. Without the supply of fuel oil, the diesel engine.ls unable to produce power which adversely affects the safety-related operation of the emergency diesel generator set.

(v) The date on which the Information of such defect or failure to comply was obtained.

October 24, 2018 (vi) In the case of a basic component which. contains a defect or falls to comply, the number and locatlon of these components in use at, supplied for, being supplied for, or may be supplied for, manufactured, or being manufactured for one or more facilities or activities subject to the regulations In this part.

The extent of condition includes pump PIN 8410219 as well as the part numbers listed in Table 1 In Appendix A. Note that PIN 8080284 ls otherwise identical to PIN 8410219 except that the ports are threaded as apposed to flanged.

The scavenging pump assemblies listed are upper level assemblies that contain either PIN 8410219 or 8080284.

The fuel pump and motor assembly utilizes PIN 8410219.

The soakback pump assemblies listed use a pump made by the same manufacturer with similar construction and therefore a~ Included in the extent of condition.

Based on ESl's investigation the Issue may extend as far back "s 2014. Therefore, any of the pumps supplied from 2014 through 2018 are considered suspect.

(vii) The corrective action which has been, is being, or wlll be taken; the name of the Individual or organization responsible for the action; and the length of time that has been or will be taken to complete the action.

For all affected customers:

ES/ recommends inspecting the bolt tightness for all pumps. The recommended bolt torque Is 108 to 120 In-lbs (12 to 13 Nm). After verifying bolt torque, a shaft freeness check is recommended. The pump shaft should be capable of being rotated by hand In either.direction. Due to the small shaft size, this check is commonly performed with a small crescent wrench or with the coupling half installed on the shaft. Inability to rotate by hand indicates loss of end clearance and the pump should be returned to ES/ for rework or replacement.

Note: For Installed pumps where it is not possible to check shaft freeness, ES/ recommends using a reduced bait torque of BO to 70 In-lbs (7 to B Nm). This is sufficient to ensure the bolts are snug while safeguarding against lass of end clearance that would otherwise go undetected.

This activity should be performed at the earliest opportunity; however, it is mare important for the Inspection ta be performed on newly installed pumps. It is expected that for pumps supplied with law bolt torque, if a problem were to develop it would be In the form of a fuel leak ~oon after installation.

For pumps that have been successfully installed for several months or years with no detectable leakage, it is less likely that balt(s) are loose and therefore the urgency of this Inspection is reduced.

For ES/:

The dedication procedures for these pumps have been revised or are being revised to add a step ta verify proper bolt torque. This will be completed prior to any future shipments. In addition, ES/ is in correspondence with the pump manufacturer to Implement corrective actions to prevent reoccu"ence.

(viii) Any advice related to.the potential defect or failure to comply about the facility, activity, or basic component that has been, Is being, or will be given to purchasers or licensees, Verification of bolt tightness Is nan-invasive and may be performed with the pump installed (and operating). The baits are external to the pump and the cover is stationary; there Is no impact to pump operation or functionality while performing this inspection.
