AGREEMENT STATE REPORT - FIXED GAUGE BROKEN SHUTTER
The following report was received via e-mail:
"The licensee notified the Department [South Carolina Department of Health and Environmental Control] at 1115 [EST] on February 13, 2018, that it had discovered a broken shutter on one of its gauges during the six-month shutter checks on February 12th. The gauge is a Berthold Model LB7440D containing 100 mCi of Cs-137. Source serial number is N-A04538DZ242A and source holder serial number is 2179. The gauge is still in service and a radiation reading of 2 mR/hr was observed on the surface of the gauge. There is no radiation exposure risk to personnel."

LOSS OF VENTILATION IDENTIFIED DURING TECHNICAL SUPPORT CENTER TEST
"On February 12, 2018, during performance of a TSC Diesel Generator Functional Test, the TSC Ventilation could not be placed in Filter Mode. Filter Mode operation is credited in the TSC habitability analysis of record. The TSC was declared non-functional due to the unavailability of the filtration system.
"The Emergency Operations Facility (EOF) is available for use as a backup TSC. Additionally, the TSC would be available for emergency response purposes for events that do not involve a release in progress.
"The NRC Resident Inspector has been notified."

At 1258 CST, TSC ventilation was declared operable. A start permissive lever was adjusted to remedy interference.
The licensee notified the NRC Resident Inspector.

UNANALYZED CONDITION FOR TORNADO GENERATED MISSILES
"On February 12, 2018, during evaluation of protection for Technical Specifications (TS) equipment from the damaging effects of tornado generated missiles, Dresden Station identified a non-conforming condition in the plant design such that specific TS equipment is considered to not be adequately protected from tornado generated missiles. Tornado generated missiles could strike the Unit 2, Unit 2/3, and Unit 3 Emergency Diesel Generator main fuel oil tank vents. This could result in crimping of the vents, which would affect the ability of the main fuel oil tanks to perform their function if a tornado would occur.
"This condition is reportable in accordance with 10 CFR 50.72(b)(3)(ii)(B) as a condition that results in the nuclear power plant being in an unanalyzed condition that significantly degrades plant safety and 10 CFR 50.72(b)(3)(v)(D) as a condition that at the time of discovery could have prevented the fulfillment of the safety function of structures or systems that are needed to mitigate the consequences of an accident.
"This condition is being addressed in accordance with NRC enforcement guidance provided in Enforcement Guidance Memorandum (EGM) 15-002, 'Enforcement Discretion for Tornado-Generated Missile Protection Noncompliance,' and DSS-ISG-2016-01, 'Clarification of Licensee Actions in Receipt of Enforcement Discretion' per Enforcement Guidance Memorandum EGM 15-002, 'Enforcement Discretion for Tornado-Generated Missile Protection Noncompliance,' Revision 1. Compensatory measures have been implemented in accordance with these documents.
"The NRC Resident Inspector has been informed of this notification."
* * * RETRACTION ON 10/11/19 AT 1031 EDT FROM SAMANTHA COSENZA TO BETHANY CECERE * * *
"The purpose of this notification is to retract event notification 53204 made on February 12, 2018, for Dresden Station. Additional review determined that the current design of all three Emergency Diesel Generators and associated Main Fuel Oil Storage Tanks Vents is consistent with the licensing basis for Dresden Station. There was no non-conformance of Dresden's tornado missile protection design, and the EDGs were operable at the time the event notification was made.
"Therefore, this event does not meet the criteria of 10 CFR 50.72(b)(3)(ii)(B) and 10 CFR 50.72(b)(3)(v)(D). The ENS 53204 report is being retracted.
