OFFSITE NOTIFICATION MADE DUE TO TRANSFORMER LEAK

"Discovery of a PCB [Polychlorinated Biphenyls] leak on a 440 gallon deenergized transformer. Leak was approximately 0.5 gallons (3-5 lbs of PCB). [The leak was] contained onsite within unit 2, 617 turbine building. Contractor clean-up [is] enroute. No personnel injury or exposure. No offsite release.

"[The licensee] contacted IEMA [Illinois Emergency Management Agency], National Response Center, and the local emergency planning center."

The licensee has notified the NRC Inspector. Notified FEMA, USDA, HHS, DOE, and EPA EOC.

INFORMATION ONLY - UNIT 4 TECHNICAL SPECIFICATION ENTRY DUE TO LOSS OF UNIT 3 STARTUP TRANSFORMER DURING UNIT 3 OUTAGE

"This is a non-emergency, information only notification to the NRCOC. Plant conditions are as follows: Unit 3 is de-fueled and Unit 4 is in Mode 1 [At 100 percent power]. The Unit 3 Startup transformer is INOPERABLE due to preplanned maintenance. The 3B Emergency Diesel Generator (EDG) became INOPERABLE due to loss of all 480V vital AC load centers on Unit 3.

"With Unit 4 in Mode 1, Technical Specification [TS] 3.8.1.1.c requires a 4-hour report to the NRC due to inoperability of 1 of 3 required EDGs onsite, concurrent with inoperability of a required Startup transformer. This report is for informational purposes only and is not required by 10CFR50.72/73.

"Spent Fuel Pool Cooling at Unit 3 remains available via 3B SFP Cooling Pump which is powered from Unit 4."

The loss of the Unit 3 480V AC load centers is still under investigation. TS 3.8.1.1.c requires Unit 4 to exit the TS action statement in 2 hours or shutdown. To exit this TS, no two battery chargers may be powered from the same motor control center. The 480V vital AC load centers for Unit 3 must be restored since Unit 4 requires at least one train from Unit 3 480V AC load centers. The licensee is in the process of performing those actions.

The licensee notified the NRC Resident Inspector.

AGREEMENT STATE REPORT - HAIRLINE CRACK FOUND IN HOUSING OF A BERTHOLD LEVEL DENSITY GAUGE

The following report was received from the State of Louisiana via email:

"On 11/04/2015, the ARSO [Assistant Radiation Safety Officer] for [the licensee] called the LA DEQ [Louisiana Department of Environment Quality] about a hairline crack on the housing of a Berthold level density gauge. The crack was noticed when the annual operational inspections were being performed. The level gauges are required to be inspected by Condition Number 6 of the licensee's radioactive material license.

"The [gauge is located] in Geismar, LA within the secure boundary the licensee's chemical plant.

"The fixed gauge is installed on a hopper/drum, but the gauge has not been used as a qc/qa [quality control/quality assurance] device since March 21, 2003, when the device was locked-out. The crack or hairline crack was not detected or documented before the November 2015 annual inspections. The notification to LA DEQ is required by Condition Number 6 of the license. The gauge remained installed on the hopper since 2003, but was not functioning as a gauge during that time.

"LA DEQ was notified on November 4, 2015, at approximately 1430 CST, that during [the licensee's] annual operational inspections, they detected a hairline crack in the housing of an installed locked-out density measuring device (gauge). The device was a Berthold gauge Model LB 7440D loaded with approximately 60 mCi of Cs-137.

"On 11/04/2015, the licensee's ARSO called LA DEQ to make a preliminary report about a hairline crack found in a gauge housing/source holder. The crack was at the union of the gauge shielding and the mounting plate of the device.

"[A contract company] has been contacted to provide services at [the licensee' facility], for packaging the source to be shipped and for the source disposal. This will be the 'corrective action' and it was speculated the crack possibly happened due to the vibration of the hopper. The source or device is not leaking. The source is not exposed or removed from the shielded position. This appears to be reportable under 10 CFR 31.5(c)(5). The source was not being used/operational when the crack was detected.

"There is no possible exposure to the plant workers because the gauge is still installed on an elevated process. Surveys were taken of the source/gauge housing and they were in the same range as before noticing the crack. The exposure level is approximately 150 mR/hr. The gauge has been locked-out since March 20, 2003. The shutter remains closed and the gauge does not cause a safety hazard to the plant personnel. The gauge operated in the open direction without a problem. [The ARSO] called and reported the incident to comply with Condition Number 6 of [licensee's] Radioactive Material License. The gauge is a Berthold, model #LB-7440D [originally] loaded with approximately 100 mCi of Cs-137 and received and installed in 1992. The SN for the source is 3029-9-90. The corrective action will be disposal by [the contractor]. The Department [LA DEQ] considers this item OPEN until the disposal. The records will be reviewed during a site visit and the next inspection."

Louisiana Event Report ID No.: LA 15-0020, T167164

AGREEMENT STATE REPORT - MEDICAL EVENT INVOLVING YTTRIUM-90

The following information was received from the State of Ohio via email:

"A medical event occurred at The Ohio State University Wexner Medical Center on Wednesday, November 04, 2015 involving the medical use of TheraSphere Yttrium-90 (Y-90) glass microsphere therapy. Upon completion of the post procedure measurements, it was noted that a high residual activity was found during the post-procedure exposure measurements. Based on the pre and post-procedure exposure measurements, it was calculated that a total of 74% of the prescribed dose was delivered to the patient. No adverse effects to patient are anticipated and the prescribing physician determined that a therapeutic dose had been received."

Intended dosage was 20.1 mCi (120 Gy)
Received dosage was 15 mCi (89 Gy)

OH Report No. 2015-017
NMED Report No. OH150011

A Medical Event may indicate potential problems in a medical facility's use of radioactive materials. It does not necessarily result in harm to the patient.
