EMERGENCY DIESEL GENERATORS DECLARED INOPERABLE

"With D.C. Cook Unit 1 in Mode 1 and 100 percent power and Unit 2 in Mode 4 during a refueling outage, the following emergency diesel generators (EDGs) were declared inoperable due to a discovered design and manufacturing issue involving some of the diesel fuel pumps/injectors in each of the following EDGs:

"Unit 1 CD (Train A) EDG, Unit 2 AB (Train B) EDG, and Unit 2 CD (Train A) EDG

"Due to both Unit 2 EDGs being inoperable, Unit 2 is required to be in Mode 5 by 1300 [EST] on 12/23/16. Unit 1 is required to restore its emergency diesel generator within 14 days (by 2300 [EST] on 1/04/17).

"In connection with both trains of Unit 2 EDGs being inoperable, this is being reported as an 8-hour report pursuant to 10CFR50.72(b)(3)(v)(D) as loss of safety function in connection with mitigating the consequences of an accident.

"The NRC Resident Inspector has been informed."

Unit 1 maintenance will be prioritized over Unit 2 and Unit 2 will most likely proceed to Mode 5.

* * * RETRACTION AT 1406 EDT ON 5/22/17 FROM RODNEY PICKARD TO JEFF HERRERA * * *

"The condition reported in ENS 52456 pursuant to 10 CFR 50.72(b)(3)(v)(D) has been evaluated, and determined not to be a loss of safety function in connection with mitigating the consequences of an accident, and is being retracted.

"With D.C. Cook Unit 1 in Mode 1 and 100% power and Unit 2 in Mode 4 during a refueling outage, the following Emergency Diesel Generators (EDGs) were declared inoperable due to a discovered design and manufacturing issue involving some of the diesel fuel pumps/injectors in each of the following EDGs: Unit 1 CD (Train A) EDG, Unit 2 AB (Train B) EDG, and Unit 2 CD (Train A) EDG.

"Subsequent endurance testing was performed on selected Delivery Valve Holders (DVH), which were the affected components of the diesel fuel pumps/injectors, to evaluate the expected degradation of the DVHs during the EDG mission. This testing determined that the identified design and manufacturing issue would not have prevented the EDGs from performing their intended safety functions. Therefore, all EDGs were OPERABLE and did not result in a loss of safety function in connection with mitigating the consequences of an accident.

"The NRC Resident Inspector was notified of this retraction."

Notified the R3DO (Kunowski).

AGREEMENT STATE - DELIVERED DOSE TO PATIENT DIFFERED BY MORE THAN 20 PERCENT

The following report was received from the South Carolina Department of Health and Environmental Control (SCDEH) via email:

"The licensee notified the Department [SCDEH] on May 15, 2017 that it had a medical event on May 12, 2017 involving a delivered dose that differed by more than 20 percent and dose that would have resulted from the prescribed dosage by more than 0.5 Sv (50 rem) to an organ or tissue. The patient was prescribed 145 Gray from I-125 prostate seed implants. The dose delivered was 103.53 Gray which is 28.6 percent below the prescribed dose."

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.

AGREEMENT STATE - SOURCE UNABLE TO BE RETRIEVED INTO SHIELDED DEVICE

The following report was received from the Louisiana Department of Environmental Quality via email:

"[On] 05/15/2017, [at] 11:50 [CDT], the Radiation Safety Officer of Team Industrial Services, Inc. called the Radiation Section of LDEQ [Louisiana Department of Environmental Quality] to report a source retrieval that occurred on 05/14/2017 [at approximately] 18:00 [CDT] at the INDORAMA VENTURES OLEFINS Refinery is Sulphur, LA at 4300 Hwy 108, Westlake, LA 70669. The camera was being used on a gridded walkway to radiograph some construction material situated on a tripod. The tripod became unstable causing the material to fall and crimp the guide tube. The source was in the collimator and was unable to be retrieved into the shielded exposure device. A retrieval crew was assembled and they were able to retrieve the source and return it to the shielded position. Two radiographers and a site RSO [Radiation Safety Officer] conducted the retrieval activities. The retrieval process was safely completed at [approximately] 20:30 [CDT] on 05/14/2017.

"A radiography exposure device was a QSA Global Model 880D, S/N D12919 and the source was an AEA Technology Model A424-9. The exposure device was loaded with 85.7 Ci of Ir-192. The guide tube was a 7 ft. tube that utilized a collimator. The exposure device and source were returned to the office for storage until being evaluated. The crimped guide tube was tested for leakage and then sent for disposal. The area was restricted to the public and controlled for the employees of Indorama. The exposures to the retrievers were minimal."
