AGREEMENT STATE REPORT - OCCUPATIONAL EXPOSURE EXCEEDING REGULATORY LIMITS
The following information was received from the State of Georgia via email:
"In accordance with Georgia Rule Chapter 391-3-17-.03-15(b)(3)(ii) [the licensee is notifying the Georgia Radioactive Material Program] of a potential extremity exposure exceeding regulatory limits to an occupational worker at Northside Hospital Atlanta. The timeline and circumstances are as follows:
"Northside Hospital received notification from Landauer ([the licensee's] personnel dosimetry vendor) on November 2, 2018, concerning an excessive reading of 58,748 millirem to an extremity dosimeter issued to [an employee] in Nuclear Medicine.
"[The licensee's] RSO immediately initiated an investigation which included a personal interview with the employee which resulted in the employee remembering the potential contamination of their ring dosimeter with a radiopharmaceutical as they were handling and injecting a patient dose during the period of use for that dosimeter; however, he was unsure as to the actual presence of contamination on the ring itself.
"The RSO assured the employee of the lack of any untoward effects but asked him for a follow-up for any skin effects that may have presented. Also it was noted that the whole body dosimeter during the same period showed only 25-30 millirem exposure.
"Based on this incident, there will be a renewed emphasis for all Nuclear Medicine Technologists that in the event of potential contamination to themselves and particularly to any personnel dosimeter, an immediate investigation by [the licensee's] RSO will be initiated and a report filed with [the licensee's] Radiation Safety Committee."

LOSS OF EMERGENCY ASSESSMENT CAPABILITY
"On 12/4/2018 at 1340 [PST], Columbia entered a planned evolution to replace the seismic monitoring system. Use of the Modified Mercalli Intensity Scale has been implemented as a compensatory measure per station procedures. The expected duration of the replacement activity will exceed 72 hours, therefore, this is being reported as a major loss of emergency assessment capability in accordance with regulation 10 CFR 50.72(b)(3)(xiii).
"Compensatory measures will remain in place until the seismic system replacement has been completed.
"The NRC Resident Inspector has been notified."

HPCI INOPERABLE DUE TO MECHANICAL DRAFT COOLING TOWER FAN BRAKE INVERTER FAILURE
"At 0935 EST on December 4, 2018, the Division 2 Mechanical Draft Cooling Tower (MDCT) fans were declared inoperable due to failure of the over speed fan brake inverter. The brakes prevent fan over speed from a design basis tornado. The MDCT fans are required to support operability of the Ultimate Heat Sink (UHS). The UHS is required to support operability of the Division 2 Emergency Equipment Cooling Water (EECW) system. The EECW system cools various safety related components, including the High Pressure Coolant Injection (HPCI) system room cooler. An unplanned HPCI inoperability occurred based on a loss of the HPCI Room Cooler. Investigation into why the Division 2 MDCT fan over speed brake inverter failed is in progress. This report is being made pursuant to 10 CFR 50.72(b)(3)(v)(D) based on an unplanned HPCI inoperability.
"The NRC Resident Inspector has been notified."
Fermi 2 is in a 14-day LCO for inoperability of HPCI and a 72-hour LCO for UHS inoperability.
* * * RETRACTION ON 1/30/19 AT 1605 EST FROM CHRIS ROBINSON TO BETHANY CECERE * * *
"The purpose of this notification is to retract EN 53772 made on December 4, 2018. Subsequent to the initial notification, the event and site Technical Specifications (TS) were reviewed further. An evaluation determined that TS Limiting Condition for Operation (LCO) 3.0.9 for barriers could be applied to the MDCT fan brakes. As a result of applying TS LCO 3.0.9 to the MDCT fan brakes, it was not necessary to declare the UHS inoperable. With the Division 2 UHS operable on December 4, 2018, the HPCI system was also operable. With HPCI operable, there was no event or condition that could have prevented the fulfillment of a safety function needed to mitigate the consequences of an accident under 10 CFR 50.72(b)(3)(v)(D). Therefore, EN 53772 is retracted and no Licensee Event Report (LER) under 10 CFR 50.73(a)(2)(v)(D) is required to be submitted.
"The licensee has notified the NRC Resident Inspector."
