RADIOGRAPHY CAMERA SOURCE DISCONNECTED

The following incident occurred in federal waters on Chevron's St. Malo platform.

On January 26, 2019, while retracting the source after a radiography shot, the radiographer determined that the source had become disconnected. The radiographer and assistant radiographer established a 2 mR boundary and contacted their radiation safety officer (RSO). The RSO dispatched a licensed source retriever to the platform.

After arriving at the platform on January 27, 2019, the source retriever was able to place the source into a shielded container. The source and camera were transported back to the licensee facility located in Houma, LA. The camera and source will be inspected/repaired by the manufacturer prior to placing them back into service.

The camera is a SPEC-150 camera, serial number 1717, containing a 33 Ci Ir-192 source, serial number ZI0603.

The licensed retriever received 275 mR during the retrieval. The radiography and assistant radiography technicians received 24 mR and 41 mR exposure.

UNIT ONE HPCI SYSTEM INOPERABLE DUE TO BLOWN FUSE

"On February 5, 2019, at 1804 [CST], during a Unit 1 High Pressure Coolant Injection (HPCI) operability surveillance, a fuse blew in the logic for the motor speed changer for the turbine. The Unit 1 HPCI system was taken out of service for planned maintenance earlier in the day. The fuse issue was not related to any maintenance activities. Had HPCI been demanded, this fuse failure would not have allowed HPCI to reach its required speed. HPCI remains inoperable pending resolution of the issue. The Reactor Core Isolation Cooling (RCIC) system was confirmed operable. There were no other systems inoperable at the time of the event. HPCI had been last successfully tested on November 6, 2018.

"This event is being reported as a condition that could have prevented fulfillment of a safety function in accordance with 10 CFR 50.72(b)(3)(v)(D). The HPCI system is a single train system and the loss of HPCI could impact the plant's ability to mitigate the consequences of an accident.

"The NRC Senior Resident Inspector has been notified."

Inoperable HPCI places the unit in a 14 day Technical Specification Limiting Condition of Operability.
