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.

AGREEMENT STATE REPORT - TROXLER GAUGE DAMAGED AT CONSTRUCTION SITE
The following report was received from the North Carolina Department of Health and Human Services via email:
"North Carolina Licensee ECS Carolinas, LLP, License Number 092-0253-1 reported that a Troxler Model 3440, S/N 24665 Moisture Density Gauge had been damaged on July 10, 2017 at a construction site in Chapel Hill, NC. The gauge contained 8 mCi of Cesium-137 and 40 mCi of Americium-241. An approved technician backed up a company vehicle over the gauge. North Carolina Radiation Protection immediately dispatched an inspector on site to perform a reactive inspection same day. Event Date and Notification Date: July 10, 2017. Licensee had cordoned off a 15+ foot barrier around the vehicle and the gauge. Surveys taken at various distances from the gauge and on contact confirmed that the sources were intact and shielded in the gauge. The gauge sustained minimal damage to the guide rod and the source rod was not extended at the time of the incident. No other local or federal authorities were contacted for this event. The gauge was returned to the manufacturer for repair or disposal. A 30-Day Report is pending from the licensee and follow-up information will be provided. NC Event Report Tracking Number: 170026. Event reportable due to: 10 CFR 30.50(b)(2)(ii)."
