| Event Text DAMAGED TROXLER GAUGE
The following was received via email:
"At approximately 1000 [EST], a Troxler Gauge was run over by a road construction roller resulting in a cracked housing of the gauge. The instrument's source probe was not extended. Initial survey results indicated 0.5 mR/hr at 12 inches (background was less than 0.1 mR/hr). An ERCIT inspector was dispatched to investigate. [The inspector's] survey indicated 15 mR/hr on contact; his report is forthcoming."
The gauge contains Cesium-137 and Americium/Beryllium sources.
The gauge was transferred to the licensee's radwaste facility.

"This notification is being made due to planned maintenance during the Semi-Annual Seismic System Functional Test. This test will result in a major loss of emergency assessment capability for emergency action level (EAL) HA6 (natural or destructive phenomena affecting VITAL AREAS), while the control room 0.1g acceleration alarm is non-functional. The emergency preparedness plan requires the 0.1g acceleration alarm indication to declare EAL HA6 during a seismic event greater than the Operating Basis Earthquake (OBE). This condition requires an 8 hour non-emergency immediate reportability to the NRC in accordance with 10 CFR 50.72(b)(3)(xiii), Major Loss of Assessment, Response, or Communication Capability.
"At approximately 1200 CST on November 17, 2015, the Semi-Annual Seismic System Functional Test will commence. While this test is in progress, seismic alarm capability is not available for EAL declaration purposes. ANO procedures provide compensatory measures of using offsite sources to obtain seismic data. It should be noted that seismic data will still remain capable of being recorded and only alarm capability is lost. The Semi-Annual Seismic System Functional Test will occur intermittently over the next four days."
The licensee has notified the NRC Resident Inspector.

The licensee returned the Seismic System to service at 1347 CST on 11/18/15.

"At 2355 (CST) on 11/17/2015, River Bend Station declared the High Pressure Core Spray [HPCS] system inoperable in accordance with Technical Specification 3.8.9, Condition E (Declare HPCS system and Standby Service Water System Pump 2C inoperable immediately) due to Division 1 Control Room Air Conditioning System HVK-CHL1C being inoperable because of a significant Freon leak on SWP-PVY32C.
"Actions taken to exit LCO: Alternated divisions of Control Room Air Conditioning System to Division 2 HVK-CHL1D in service and Division 1 HVK-CHL1A in standby."
The basis for declaring High Pressure Core Spray inoperable was that the control room chiller also chills the switchgear room that supplies power to the HPCS. HPCS was out of service for less than one hour while the chillers were swapped from Division 1 to Division 2.

"This is a non-emergency eight hour notification in accordance with 10 CFR 50.72(b)(3)(iv)(A), for an automatic actuation of the 3A Emergency Diesel Generator (EDG).
"On 11/18/15 at approximately 0326 [EST] a loss of power was experienced on the 3A 4KV Bus. The redundant 3B 4KV bus did not experience a loss of power. All systems operated as expected following the loss of power with the 3A EDG automatically sequencing onto the 3A 4KV bus and the load sequencer loading as designed. At the time of the actuation, Unit 3 was in a refueling outage in MODE 5. Investigation into the cause of the loss of power is in progress. There was no impact on Unit 4 operation during this time."

"Unit 3 experienced Loss of Offsite Power due to lockout on Unit 3 Startup transformer. The 3B EDG auto started and loaded on the 3B 4KV Bus. The 3A Sequencer was out of service and prevented the 3A EDG from auto starting and supplying 3A 4KV busses. With only 3B 4KV bus powered from an EDG and no offsite power to Unit 3, Unit 3 entered an Unusual Event.
"Core cooling was restored with 3B RHR pump at 2343 EST. At 2350 EST, 3A 4KV Bus was manually loaded onto 3A EDG and conditions for Unusual Event were terminated.
"Additionally this is a non-emergency eight hour notification in accordance with 10CFR50.72(b)(3)(iv)(A), for a valid automatic actuation of the 3B Emergency Diesel Generator."
While core cooling was lost, the core experienced a 3 degree heat up. Spent fuel pit cooling has also been restored. The cause of the transformer lockout is under investigation.
Unit 4 was unaffected and continues to operate at 100% power.
The licensee has notified state and local authorities about this event. The licensee has also notified the NRC Resident Inspector. | |
