GLAND SEAL EXHAUSTER - AUTOMATIC TRIP FUNCTION INOPERABLE
"On January 1, 2019 at approximately 0454 EST, while performing planned maintenance activities on the Feedwater Distributed Control System (FW DCS), it was discovered that the automatic trip instrumentation of the Gland Seal Exhauster (GSE) was inoperable. The automatic GSE trip is assumed in the safety analysis for the Control Rod Drop Accident (CRDA) and is required when Thermal Power is less than or equal to 10%.
"The automatic trip function of the GSE was inoperable for 1 minute, 19 seconds. No Control Rod movement occurred while the automatic trip of the GSE was inoperable. There was no adverse impact to public health and safety or to plant employees and there was no radiological release.
"This report is being made pursuant to 10CFR50.72(b)(3)(v)(C) and 10CFR50.72(b)(3)(v)(D).
"The NRC Resident Inspector has been notified."

EN Revision Text: PART 21 REPORT - FAILURE TO MEET RELIABLE/CONSISTENT OPERATION OF COOLING FAN ON POWER SUPPLY 16-AAT907B
The following is a synopsis of information received via fax:
DRS Consolidated Controls Inc. (currently Leonardo DRS Naval Power Systems, henceforth referred to as NPS) provided eleven, 48 VDC power supplies, Part Number 16-AA T907B to Wolf Creek Generating Station in 2018. It was discovered in 2019 by Wolf Creek that there was anomalous fan performance occurring within this power supply after several months of operation. These issues were in the form of the following: fan noise and fan failure to operate.
The power supplies were replaced by Wolf Creek upon discovery. NPS and the power supply manufacturer were notified of the issue to begin investigation on root cause and remedial actions.
Wolf Creek Generating Station is the only power plant affected by this deviation.
