"At 0745 EDT on August 24, 2018, the Active Seismic Monitoring System failed a planned surveillance test and was declared inoperable. Compensatory measures to provide alternative methods for event classification of a seismic event have been implemented in accordance with the Fermi 2 Emergency Plan procedures. The compensatory measures include the use of information provided by the United States Geological Survey (USGS) to confirm if an earthquake has occurred within a 100 mile radius.
"The loss of the Active Seismic Monitoring System is reportable to the NRC within 8 hours of discovery in accordance with 10CFR50.72(b)(3)(xiii).
"No seismic activity has been felt onsite and the USGS recorded no seismic activity in the area.
"The NRC Resident Inspector bas been notified."
* * * RETRACTION FROM JEFF GROFF TO VINCE KLCO ON SEPTEMBER 13, 2018 AT 1524 EDT * * *
"After further review the Active Seismic Monitoring system was removed from service for planned maintenance for a duration less than 72 hours with appropriate compensatory measures established. Therefore, no major loss of emergency assessment capability occurred. In addition, the surveillance tests were re-performed and the Active Seismic Monitoring System was declared Operable. Therefore, no reportable condition existed and EN 53562 reported on August 24, 20I8 is being retracted.
"The NRC Resident Inspector has been notified."

NMSS_EVENTS_NOTIFICATION (EMAIL) | | This material event contains a "Less than Cat 3" level of radioactive material. | Event Text AGREEMENT STATE REPORT - REMOVABLE CONTAMINATION ON A SEALED SOURCE
The following information was obtained from the State of New York via fax:
"Columbia University notified the New York State Department of Health (NYSDOH) on August 7, 2018 [regarding an August 2, 2018 event] of the detection of 592 Becquerel (0.016 microCurie) of removable radioactive material on a 10 milliCurie Ni-63 sealed source contained in a Shimadzu GC-8A II gas chromatography mass spectroscopy unit. The manufacturer and model number of the source were not available. The licensee immediately suspended the operation of the unit and placed the unit in storage. The source will be disposed of as radioactive waste and the equipment will be decontaminated prior to proper disposal by an authorized waste broker."
New York Report Number NYDOH-18-02
THIS MATERIAL EVENT CONTAINS A "LESS THAN CAT 3" LEVEL OF RADIOACTIVE MATERIAL
Sources that are "Less than IAEA Category 3 sources," are either sources that are very unlikely to cause permanent injury to individuals or contain a very small amount of radioactive material that would not cause any permanent injury. Some of these sources, such as moisture density gauges or thickness gauges that are Category 4, the amount of unshielded radioactive material, if not safely managed or securely protected, could possibly - although it is unlikely - temporarily injure someone who handled it or were otherwise in contact with it, or who were close to it for a period of many weeks.

| Person (Organization):
MIKE ERNSTES (R2DO)
PART 21 GROUP (EMAIL) | Event Text PART 21 - MOTOR OPERATED POTENTIOMETER DEFECT
"A batch of Motor Operated Potentiometers (MOPs) supplied by ESI [Engine Systems Inc.] were found to contain motors that, as they accumulate run time, exhibit increasing current draw and eventually exceed the MOP circuit allowance. Consequently, the motor operation becomes erratic which leads to a sluggish MOP. The MOP is used in a safety-related system to control emergency diesel generator (EDG) output voltage. Failure of the MOP to operate properly can negatively affect the EDG output voltage which affects associated components required to safely shutdown the nuclear reactor.
"ESI will revise the test procedure to incorporate an extended run time while trending the motor for any adverse changes. This will be completed within 30 days and will prevent reoccurrence.
"For Catawba, any MOPs from this batch are considered suspect and may be returned to ESI for rework or replacement. For units installed, the motor performance should be assessed prior to continued use. The voltage measured across terminals 3(-) and 4(+) while the MOP is operating should remain steady within a range of 22.8 to 25.2 VDC. Any step change or reduction in voltage is an indication of motor deterioration.
"The root cause of the excessive current draw was found to be build-up of carbonaceous deposits between the commutator sections of the motor either from the carbon brushes, contamination, or a combination of the two. As the motor accumulated run time, the deposits propagated to the point of a low resistance path between commutator sections which are wired to the armature poles. This affected the magnetic field within the motor which had a direct impact on motor performance. ESI has limited the issue to a single date code of motors supplied within a single batch of MOPs, as listed.
