AGREEMENT STATE REPORT - UNPLANNED CONTAMINATION

The following report was received from the South Carolina Department of Health and Environmental Control via e-mail:

"This event was first reported to the State as an allegation but is now being reported as an incident because of our recent IMPEP [Integrated Materials Performance Evaluation Program] review.

"The unplanned contamination was because of the dissolution of a Po-210 Static Eliminator containing 125 microcuries. The contamination was discovered when a Graduate Research Assistance was surveying himself upon exiting the lab. The RSO was notified and the lab was thoroughly decontaminated. The laboratory was posted and access was restricted. The licensee was required to report this incident within 24 hours of discovery because the unplanned contamination caused a restricted area to be closed for more than 24 hours."

LOSS OF SAFETY FUNCTION - CONTROL ROOM ENVELOPE INOPERABLE

"At 2158 [CDT] a door to the Control Room Envelope was left unsecure. GGNS [Grand Gulf Nuclear Station] identified that a loss of Safety Function occurred due to a breach in the Control Room Envelope resulting in inoperability of both divisions of Standby Fresh Air and therefore could have prevented fulfillment of its safety function. The Control Room Envelope was inoperable for one minute. This event is being reported under 10CFR 50.72(b)(3)(v)(D), as any event or 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."

The licensee notified the NRC Resident Inspector.

LOSS OF SECONDARY CONTAINMENT DUE TO FAILURE OF NON-SAFETY RELATED DISCHARGE DAMPER

"On July 10th, 2017 at 0250 hrs. [EDT] a loss of secondary containment differential pressure (D/P) occurred due to failure of a non-safety related discharge damper associated with 2V205B Reactor Building Zone II Exhaust Fan. This caused a reduction in Reactor Building Zone II (Unit 2) D/P to less than the required 0.25 inches WC [Water Column].

"2V205A Reactor Building Zone II Exhaust Fan was manually started and Reactor Building Zone II D/P was restored to greater than 0.25 inches WC by 0301 hrs.

"Reactor Building Zone 1 (Unit 1) and Zone 3 (Units 1&2) ventilation remained in service and stable.

"This event is being reported under 10 CFR 50.72(b)(3)(v)(c) and per the guidance of NUREG 1022, Rev. 3, section 3.2.7 as a loss of a Safety Function. There is no redundant Susquehanna Secondary Containment system."

The licensee notified the NRC Resident Inspector.

OFFSITE NOTIFICATION DUE TO CONTRACT EMPLOYEE FATALITY

"At approximately 14:10 Eastern Daylight Time (EDT), the Control Room was notified of a contract employee experiencing a non-work related medical emergency within the protected area in the service building. First responders were immediately dispatched. Off-site assistance was requested. The individual was transported to the New Hanover Regional Medical Center. No radioactive material or contamination was involved. At 16:02 EDT, hospital officials notified plant personnel that the patient was declared deceased.

"This notification is being made in accordance with 10 CFR 50.72(b)(2)(xi) for a situation related to the health of on-site personnel for which a notification to other government agencies is planned. The Occupational Safety and Health Administration (OSHA) will be notified.
