"On March 25, 2018 at 1833 CDT, while at 100 percent power, Farley Unit 1 (FNP-1) conservatively declared a single Main Steam Isolation Valve (MSIV) inoperable on the 1C Steam Generator line due to indication of Steam Generator pressure rise with a corresponding reduction in flow of that loop. FNP-1 began a reactor shutdown at 0400 CDT on March 26, 2018 to establish plant conditions to support testing the affected main steam line MSIVs while in the required action time of Technical Specification 3.7.2. At 1338 CDT on March 26, 2018, testing confirmed that the single MSIV was inoperable and that valve disassembly will be required. The duration of the valve repair would exceed the required action time of Technical Specification 3.7.2. This report is being made in accordance with 10 CFR 50.72(b)(2)(i), as a plant shutdown required by technical specifications.
"The licensee has notified the NRC Resident Inspector."
* * * UPDATE FROM DOUGLAS HOBSON TO KEN MOTT AT 0202 EDT ON 5/16/18 * * *
"This EN [event notification] is being updated to clarify the reporting criteria as 'Voluntary'. Farley Technical Specification 3.7.2 allows continuous operation in MODE 2 with an INOPERABLE MSIV as long as the other MSIV in the affected Main Steam Line is closed. The initiation of the shutdown was performed as a prudent action to repair and restore OPERABILITY of the affected MSIV and was not a requirement of the Farley Technical Specifications."
The licensee notified the NRC Resident Inspector.
The R2DO (Masters) was notified. |

NMSS_EVENTS_NOTIFICATION (EMAIL) | Event Text AGREEMENT STATE REPORT - MISADMINISTRATION OF INCORRECT MEDICATION
"A lung scan was incorrectly performed at Wesley Medical Center in Wichita, Kansas last Friday, the 4th of May. It was reported [to the State] at approximately 1500 [CDT] on 5/7/2018. The DTPA [pentetic acid] dose was supposed to go through a nebulizer, and an MMA [methylmalonic acid] dose was supposed to be injected for perfusion, but they accidentally injected the DTPA instead. The patient was able to go through the scan as normal, but the end result is that 40 mCi of DTPA (what should have been the MMA dose, by [the State's] understanding) were injected instead of 4 mCi (what should have been the DTPA dose). The bladder dose was over 5 rads.
"A full report has been promised by the licensee tomorrow, which will be forwarded to [the NRC] and entered into NMED [Nuclear Material Events Database]."
It is unknown if the patient and the prescribing physician have been notified at the time of this report.
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. |

NMSS_EVENTS_NOTIFICATION (EMAIL) | Event Text AGREEMENT STATE REPORT - SOURCE DISCONNECTED FROM GAUGE'S OPERATING ROD
"On May 7, 2018, the Agency [Texas Department of State Health Services] was notified by the licensee's radiation safety officer [RSO] that on the night of May 5, 2018, they discovered the 100 milliCurie (original activity) source had disconnected from the operating rod of a Berthold model P2608.100 gauge. The RSO stated a set of tongs were used to remove the source from the vessel and place it in a lead pig designed for the source. The RSO stated the manufacturer has been contacted for assistance in repairing the gauge. The individuals who removed the source from the vessel were wearing dosimetry and the RSO stated they were sending the dosimeters in for processing. The RSO stated they had no reason to believe any individual exceeded any limit. Additional information will be provided as it is received in accordance with SA-300."
Texas Incident # 9570
* * * UPDATE ON 6/20/2018 AT 1117 EDT FROM ART TUCKER TO DONG PARK * * *
The following was received via e-mail:
"During the licensee's investigation of this event, the radiation safety officer (RSO) found that the source on a second, almost identical, gauge had also separated from the operating rod. The second gauge, model HPS-1, contains a 500 milliCurie cobalt - 60 source. The failure does not create an exposure risk to any individual. The RSO stated they had received the results for the dosimetry sent for processing from the first reported failure and all readings were 0.0 millirem. The highest lifetime dose for any individual in the report was 105 millirem. Additional information will be provided as it is received in accordance with SA-300."

NMSS_EVENTS_NOTIFICATION (EMAIL) | Event Text STUCK SHUTTERS ON TWO GAUGES
During a periodic inventory check at the Columbia Falls, MT location, the Facility Radiation Safety Officer discovered two Ohmart SHF1 source holders with inoperable shutter mechanisms. Both Cs-137 sources (10 milliCuries and 50 milliCuries) are in areas where exposure to the sources is minimized by their inaccessible locations. Weyerhaeuser has been in contact with the manufacturer of the level gauge (Ohmart/Vega) about removing the inoperable source holders and replacing with two (2) new source holders.
The licensee contacted NRC Region 4 (Torres). |

"At 1750 CDT, the Arkansas Nuclear One, Unit 1 (ANO-1) reactor tripped due to the trip of the 'B' Main Feedwater Pump. Unit 1 was at 10 percent power with escalation of power in progress with one Main Feedwater Pump in service. Investigation is in progress as to the cause of the Main Feedwater Pump trip. The Main Feedwater Pump trip resulted in RPS [reactor protection system] actuation on loss of both Main Feedwater Pumps and resulted in Emergency Feedwater (EFW) actuation. All Control Rods inserted into the core properly and the reactor was verified shutdown.
"EFW experienced a half-trip on the 'A' train of Emergency Feedwater Initiation and Control (EFIC) at time of system actuation, but was successfully actuated manually immediately upon discovery. Train 'B' EFIC actuated in Automatic as designed. The half-trip of the 'A' train of EFIC is currently believed to be associated with EFIC Channel 'C'; however, investigation is underway to verify this.
"Currently, ANO-1 has been stabilized and is being maintained in Mode 3 with Auxiliary Feedwater in service. Heat removal is via Turbine Bypass valves to the Condenser.
"No radiological releases have occurred due to this event."
There was no effect on Arkansas Nuclear One, Unit 2. The licensee notified the NRC Resident Inspector and the State of Arkansas. |

"On May 16, 2018 at approximately 1425 CDT, two grass fires started in the Owner Controlled Area surrounding South Texas Project (STP) Nuclear Generating Station. The Bay City Volunteer Fire Department was called to the site to fight the fire. Reinforcements from Tres Palacios Oaks, Midfield and Markham Fire Departments were called in to assist with firefighting efforts. The grass fires were extinguished on May 16, 2018 at 2046 CDT. The fires occurred outside the protected area of the plant and presented no danger to the public or the safe operation of the units.
"On May 16, 2018 at 2202 CDT, STP Nuclear Generating Station issued a press release to inform area residents."
