"At approximately 1330 CST on Tuesday, December 12, 2017, Grand Gulf Nuclear Station declared Division 3 'C' Battery inoperable due to questions concerning battery terminal connection continuity. Technical Specification 3.8.4, DC Sources - Operating, Condition E, Required Action E.1, requires the station to declare the High Pressure Core Spray System inoperable immediately. The Division 3 'C' Battery and High Pressure Core Spray System was declared operable and the LCOs [Limiting condition of operation] were declared met at 1731CST on Tuesday, December 12, 2017. Based on field measurements of terminal torque and resistance, the as-found and as-left terminal resistance micro-ohm readings indicated satisfactorily all times. Formal evaluation of the as-found condition of the battery is in progress.
"This report is to notify the NRC of a loss of safety function on the High Pressure Core Spray System."
The NRC Resident Inspector was notified.
* * * UPDATE AT 1612 EST ON 12/27/17 FROM GERRY ELLIS TO S. SANDIN * * *
The report is retracted based on the following:
"This was initially reported under 50.72(b)(3)(v)(D). However, after subsequent investigation of the identified condition, a degraded condition was confirmed to not exist. The 1C3 battery bank connections were torque checked, inspected, and resistance values were checked. All torque, resistance values and seismic condition were confirmed to be satisfactory. The operability evaluation confirmed that the battery was and remained operable, and therefore the initial determination of operability and reportability was incorrect.
"Division 3 Battery 1C3 was at the time of discovery OPERABLE and therefore this is not a reportable condition."
The licensee informed the NRC Resident Inspector.

The following information was received from the State of Illinois:
"The University of Chicago Medical Center reported an underdose of Y90 Theraspheres today [12/19/17] to a patient. 53.4 % of dose was delivered with 46.6% stuck in catheter. 21 mCi was ordered and 11.21 was delivered. CT scan verified dose administered in correct location. On 12/18/17, it was still undetermined why remaining dose hung up in catheter. Additional dose [is] being ordered to complete the therapy as a fractionated dose. The licensee is investigating why the catheter became blocked. A 15 day written report will follow."
Illinois Incident: IL177059
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. |

| This material event contains a "Less than Cat 3 " level of radioactive material. | Event Text AGREEMENT STATE REPORT - STOLEN AND RETRIEVED TROXLER GAUGE
The following information was excerpted from an email received from the State of Florida:
The State of Florida received a notice on 11/15/17 that a Troxler Gauge and a company vehicle was stolen from the licensee by an employee. A City of Orlando Police report was issued (2017-442672). On 12/7/2017, a notice was received from the licensee to inform State of Florida Bureau of Radiation Control that the gauge was found intact and undamaged.
The Troxler moisture density gauge is a model number 3440; serial number 27931; Cs-137/AmBe; 8mCi/40mCi.
Florida Incident Number: FL17-298.
THIS MATERIAL EVENT CONTAINS A "LESS THAN CAT 3" LEVEL OF RADIOACTIVE MATERIAL
Sources that are "Less than IAEA Category 3 sources," are either sources that are very unlikely to cause permanent injury to individuals or contain a very small amount of radioactive material that would not cause any permanent injury. Some of these sources, such as moisture density gauges or thickness gauges that are Category 4, the amount of unshielded radioactive material, if not safely managed or securely protected, could possibly - although it is unlikely - temporarily injure someone who handled it or were otherwise in contact with it, or who were close to it for a period of many weeks.

| Event Text AGREEMENT STATE REPORT - POTENTIAL OVER-EXPOSURE
The following was excerpted from an email received from the State of Florida:
The State of Florida received a notice of an over-exposure from the licensee. An employee received a whole body dose of 5019 mR read on her dosimeter on 10/10/2017. The investigation determined that the most likely cause of the over-exposure was due to an unusual number of equipment failures with the synthesis units requiring employee intervention to correct the issues. Dose rates and doses to the employee were not being monitored real time. The employee has been retrained on the standard operating procedures. Alarming personal electronic dosimeters have been purchased and are in use to alert personnel of the radiation fields.
