AGREEMENT STATE REPORT - MEDICAL UNDERDOSE

"A prostate brachytherapy implant using I-125 performed at Fauquier Hospital on 6/25/2015, resulted in a dose distribution having a D90 percent of 97Gy as measured on post implant CT done on 8/12/15. The written directive prescribed a D90 percent of 145Gy. The implanted dose of 97 Gy is 66.9 percent of the intended 145 Gy. The patient was notified and is being monitored to determine if additional treatment is required.

"The final determination was not made until 10/8/15 and Fauquier notified VRMP [Virginia Radioactive Materials Program] by email on 10/8/15. A telephone conversation was held on 10/13/15 regarding the 15 day written report. VRMP will review the report and determine whether an inspection will be performed."

AGREEMENT STATE - STUCK OPEN SHUTTER ON VESSEL LEVEL GAUGE

The following report was received from the Texas Department of State Health Services via email:

"On October 13, 2015, the licensee [BASF Corporation] reported to the Agency [Texas Department of State Health Services] that during routine gauge inspection and shutter checks, its [BASF Corporation] staff found the shutter on one of its Ronan SA-1 gauges, containing a 10 milliCurie cesium-137 source, was stuck in the open position. The gauge normally operates with the gauge in the open position and due to its location on the side of a vessel there is no risk of exposure. The licensee has contacted the manufacturer to schedule repairs. An investigation into this event is ongoing. Further information will be provided as it is obtained in accordance with SA-300.

"Gauge/source Information: Gauge: Ronan model SA-1 -- (no unique serial number for the source holder)
"Source: 10 mCi cesium-137 -- SN: 6727GK"

DIESEL GENERATORS STARTED AFTER TRANSMISSION LINE LIGHTNING STRIKES

"This report is being made under 10CFR50.72(b)(3)(iv)(A) 'any event or condition that results in a valid actuation of any system listed in paragraph (b)(3)(iv)(B) of this section' due to the automatic start of 'A' and 'B' Standby Diesel Generators.

"The automatic start of the Standby Diesel Generators occurred on a valid bus under-voltage condition caused by severe weather (lightning strikes) in the DAEC [Duane Arnold Energy Center] area. The Standby Diesel Generator output breakers did not close onto their respective essential buses. Essential electrical buses remained powered from off-site circuits through their normal power supply transformer, 1X3 Startup Transformer, during and after the event.

"The Standby Diesel Generators have been returned to the standby readiness condition. Both credited off-site power circuits were available before the event and remain available after the event."

The licensee notified the NRC Resident Inspector.

UNANALYZED CONDITION DUE TO PRESSURIZER HEATER BANK POTENTIAL CIRCUIT FAILURE VULNERABILITY

"The isolation function when transferring control from the Main Control Room to the Alternate Shutdown Panel (AI-185) for Pressurizer Heater Bank No. 4 (including Groups No. 10, No. 11, and No. 12) has been identified as a potential circuit failure.

"Identification of the potential circuit failure vulnerability is for Pressurizer Heater Bank No. 4 when isolated from Alternate Shutdown Panel (AI-185) and operated locally from Motor Control Center (MCC-4C1) for Alternate Shutdown Fire Areas 41 (Cable Spreading Room) and 42 (Main Control Room).

"The vulnerability involves an external hot short affecting the conductor connecting to the control room switch which may keep the 94/10 relay energized and defeat MCC control of the heaters. In a postulated event, a fire in the control room could prevent the heaters from energizing when demanded, or cause the heaters to unintentionally energize.

"This condition is being reported in accordance with 10 CFR 50.72(b)(3)(ii)(B) as an unanalyzed condition. Per National Fire Protection Association (NFPA) 805, fire watch is an adequate compensatory measure. Therefore, this vulnerability has been added to the existing NFPA 805 Fire Protection compensatory measure for Fire Area 41. For Fire Area 42, the Main Control Room is continuously staffed, which has been credited as the compensatory measure.

"The NRC Resident Inspector has been notified."
