PART 21 - ANOMALY RELATED TO MICRO SWITCHES
The following report was received via email:
"Based on test data, Rotork believes an unsafe condition may exist as defined under 10 CFR 21. The adhesive formulation used for the construction of V12 and K5 safety related micro switches was altered by the switch maker's sub-supplier. K5 switches have no reported failures, but are affected because of construction. The altered adhesive formulation outgases an insulating material at elevated temperatures, which coats the switch contacts as it cools and can prevent the conduction of electricity."
* * * UPDATE AT 0938 EDT ON 10/31/16 FROM PATRICK A. SHAW TO S. SANDIN VIA FAX * * *
"This letter provides an update to the Rotork Controls Inc. Part 21 filing submitted May 4th 2016; documented in U.S.NRC Event Number 51907.
"Rotork have developed versions of the V12 & K5 switches that eliminate adhesive from the materials of construction.
"Evaluation of pre-production V12 switches, by thermal aging for 10 days at 125øC (257F), demonstrate the switch non-metallic housing and plunger also outgas materials that contributed to the accumulated contamination observed on switch electrical contacts as reported in Event 51907. The cause of the new outgassing sources and extent of condition is currently being investigated. For the moment suitable replacement switches remain unavailable that correct the issue reported in Event 51907.
"At this point in time, Rotork do not have grounds to believe the extent of condition is altered from that reported in Event Number 51907."

LOST ELECTRON CAPTURE DEVICE
Four electron capture detectors (ECDs) were shipped at the same time from Shanghai to Wilmington, DE. The ECDs were shipped by air freight and three of the ECDs arrived at the beginning of October. The remaining ECD has not arrived and a search is ongoing.
Source: Ni-63, 15 mCi fully encapsulated
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.

AGREEMENT STATE REPORT - UNABLE TO RETRACT RADIOGRAPHY CAMERA SOURCE
The State of Texas provided the following report via email:
"On October 21, 2016, the Agency [Texas Department of State Health Services] was notified by the licensee that one of its radiography crews were unable to retract a 71 curie iridium-192 source into a QSA 880D radiography device. The radiographers had placed the guide tube stand on a wooden box to complete an exposure when, during the exposure, the stand fell off the box and landed on the guide tube crimping it enough that the source would not pass by it.
"The radiographers contacted the licensee's radiation safety officer who sent a team of individuals to recover the source. The recovery team placed lead shielding over the source and was able to remove the crimp enough to retract the source back into the exposure device. No one involved in the event received an exposure that exceeded any limit. No member of the general public was exposed due to this event. Additional information on this event will be provided in accordance with SA-300."
The event location was Exxon Mobil in Beaumont, TX.

AGREEMENT STATE REPORT - SOURCE DISCONNECT
The following was received from the State of Minnesota via email:
"At approximately 0815 CDT on Friday, 10/21/16, radiographers for Midwest Industrial X-Ray experienced a source disconnect while working on a project for Excel. The project was taking place outside of Waverly, MN, in a rural area. A 34 Ci source (serial number XF2112, model G60) of Ir-192 experienced a disconnect from a SPEC 150 exposure device. The RSO for Midwest Industrial X-Ray, was dispatched to the site and arrived at 1345 CDT on 10/21. Source retrieval was completed by 1445 CDT. Exposures were checked on all involved, with a maximum exposure of 3 mR. Midwest Industrial X-Ray is performing an analysis to determine the cause of the disconnect and will submit a written report within 30 days. More information from the Minnesota Department of Health is forthcoming." |

HIGH PRESSURE COOLANT INJECTION (HPCI) INOPERABLE
"On October 31, 2016, at 0239 hours [CDT], a defect (minor audible through-wall leak) was identified on the steam line drain valve 1-2301-55, HPCI Steam Line Drain Line Steam Trap Outlet Valve. The defect was identified by Operations personnel traversing through the HPCI room as part of normal rounds. HPCI was declared inoperable under Tech Specs 3.5.1, Condition G. The Reactor Core Isolation Cooling (RCIC) system was verified operable. HPCI remains available [but not operable]. The leak has been isolated. The 1-2301-55 is a manual valve downstream of the HPCI steam line drain trap. In a standby line-up, this line drains condensation from the HPCI steam supply line to the main condenser. During operation in an accident scenario, this line drains condensation from the HPCI steam supply line to the Torus via a drain pot. The location of the defect is in class 2 safety related piping.
"HPCI is a single train safety system and this notification is being made in accordance with 10CFR50.72(b)(3)(v)(D).
"The NRC Resident Inspector has been notified."
Technical Specification 3.5.1, condition G requires that HPCI be Operable within 14 days. |

CONTAINMENT SUMP SUCTION VALVE OPENED DURING CONTAINMENT SPRAY PUMP TESTING
"On October 26, 2016, the Harris Nuclear Plant was in Mode 6 with core reload complete, the reactor head removed, and reactor cavity water level greater than 23 feet. The refueling water storage tank (RWST) was less than 23.4% level as expected for the refueling conditions.
"During surveillance testing to adjust the eductor flow throttle position, the containment spray pump was started in recirculation mode with the discharge valve shut. With RWST level less than 23.4%, logic was satisfied to actuate Engineered Safety Features Actuation System (ESFAS) Functional Unit 8, containment spray switchover to containment sump. The containment sump suction valve opened in accordance with the design, however the action was unexpected by the operators. Therefore, operators secured the containment spray pump and shut the containment sump suction valve. ESFAS Functional Unit 2, Containment Spray, was not actuated and water did not flow through the containment spray nozzles. This event is reported as a specified system actuation in accordance with 10 CFR 50.72(b)(3)(iv)(A) due to the opening of the containment sump suction valve.
"This event did not impact the health and safety of the public."
The licensee has notified the NRC Resident Inspector. |

OFFSITE NOTIFICATION FOR TRITIUM CONTAMINATED WATER SPILLED TO STORM DRAIN
"On October 31, 2016, an informal, voluntary communication was made to the Louisiana Department of Environmental Quality (LDEQ) and the Saint Charles Parish Emergency Operating Center concerning a spill of greater than 100 gallons (estimated 150 gallons total) of Tritium contaminated water to the storm drains located within the Protected Area. Tritium activity was 8.201E-06 micro Ci/ml and no detectable gamma activity. The spill lasted approximately 5 minutes before the pump moving the tritium contaminated water was secured. The contaminated water came from the Condensate Polisher Backwash Storage Tank and discharged from a [loose] hose connection going to a baker tank located within the protected area."
The licensee has notified the NRC Resident Inspector. |
