The following information was provided by the State of Arkansas via email:
"During routine shutter checks performed by the licensee on June 6, 2017, the licensee noted that the shutter would not close.
"The gauge is identified as Berthold Model LB 300 L source holder containing 0.189 milliCuries of Cobalt-60.
"The gauge remains operational in the normal use location and the RSO will place additional signs in the area. No maintenance is planned in the area that would require closing of the shutter. The RSO has performed a radiation survey to ensure that radiation exposure is maintained at less than 2 mR/hr in the vicinity of the gauge.
"The licensee has contacted the technical representative who was expected to be at the facility on July 6, 2017, for other maintenance and will examine this gauge.
"In accordance with RH-1502.f.2 (10 CFR 30.50(b)(2)) the malfunctioning shutter is reportable within 24 hours.
"The State of Arkansas is awaiting a written report from the licensee and final disposition information for the gauge. The State's event number is AR-2017-003. " |

The following information was received from the State of Maine via email:
"The following is a brief description of the event that occurred today in the [Maine Medical Center] (MMC) Cath Lab during an lntravascular Brachytherapy (IVB) case.
"The source train was deployed to treat the 1st dwell position of the cardiac stent. Following delivery of the prescribed dose to the 1st dwell position the source train became stuck during return to the afterloader and could not be freed. This required complete removal of the catheter with the source train and placement of it in the bailout box.
"As a result, only 1 dwell position was treated causing the delivered dose to vary by more than 20 percent of the prescribed dose.
"The prescribed dose was 1840 REM. MMC does not have the exact delivered dose estimate, but it is approximately 50 percent of the prescribed [dose] because they had planned on 2 dwell positions.
"MMC will follow this up with a full written report as required by SMRRRP G.3045.D. The Licensee will be providing a full report to the State within 15 days as required."

The following report was received via e-mail:
"Preston was sending a Troxler gauge to Troxler located in North Carolina for a repair of a faulty battery pack. Preston scheduled a package pick-up by [common carrier] on May 8, 2017 from Preston's Macon hub. The licensee stated the typical expected turn-around time for a gauge repair is 3 weeks. Troxler does not send the licensee a receipt confirmation when they receive the customer's gauge. On June 6, 2017, when the licensee had not received the gauge back from Troxler, they made a call to Troxler inquiring about the repair status of the gauge. Troxler informed the licensee they had not received the gauge. The licensee contacted [the common carrier] and asked them to track down the gauge. Based on the tracking information the licensee has, the gauge was last scanned on May 9, 2017 in TN. After some search, [the common carrier] scanned the package on either 5/18 or 5/19/17 at their International Bond Cage. According to [the common carrier], the package would have been scanned daily if it were shipped internationally. [The common carrier] will continue to search for the package. In the meantime, the licensee will follow-up with a written report."

Device: Troxler 3430, S/N 28005
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.

"This is to report the Salem Unit 2, 2C Emergency Diesel Generator (EDG) actuation due to an invalid signal.
"This report is being made per paragraphs 10CFR50.73(a)(1) and 10CFR50.73(a)(2)(iv)(A) to address the invalid actuation of the 2C EDG on April 16, 2017, while performing the 2C Safeguards Equipment Controller (SEC) Mode OPS Surveillance test.
"Plant conditions: Salem Unit 2 was in mode 5 at the time of the invalid actuation.
"On April 16, 2017, at approximately 1053 [EDT] while performing Solid State Protection System (SSPS) testing of the 2C SEC, the 2C Emergency Diesel Generator (EDG) output breaker was manually opened per the associated procedure step. The EDG output breaker unexpectedly reclosed and the 2C 4kV vital bus loaded onto the EDG in SEC Mode 2.
"The cause of the 2C EDG output breaker reclosure and 2C 4kV Vital bus loading during testing was determined to be two faulty input block switches in the 2C SEC. When Step 5.2.27 of the test procedure was performed, the 2C SEC 'input block' switches failed to block a 'blackout' actuation signal. This resulted in the breaker reclosure and loading of the 2C Vital Bus onto the EDG. Trouble shooting identified that the two failed switches exhibited high resistance across the switch contacts which is indicative of being in a 'fail to block' (the input signal) condition.

The licensee will also notify the States of New Jersey and Delaware. |

"At 0958 hours (CDT), during planned surveillance testing of the Division 3 Shutdown Service Water (SX) subsystem, the Division 3 SX pump tripped for unknown reasons. The Division 3 SX subsystem was declared inoperable and in accordance with Technical Specification 3.7.2, Action A.1, the High Pressure Core Spray (HPCS) system was declared inoperable. Since the HPCS system is a single train safety system, this event is reportable under 10CFR50.72(b)(3)(v)(D). An investigation is underway to determine the cause of the SX pump trip.

"At 1219 [EDT] on June 15, 2017, annulus vacuum exceeded its pressure limit. At that time, the Shield Building was declared inoperable in accordance with Technical Specification 3.6.15 Condition A and B, due to the inoperability of the Shield Building (CRE). At 1222 [EDT], annulus pressure returned to normal, Shield Building was declared operable and LCO 3.6.15, Condition A and B were exited.
"The temporary loss of the Shield Building resulted from a loss of pressure control in the Auxiliary Building caused by a loss of Auxiliary Building General Ventilation. The Auxiliary Building Gas Treatment System was started to maintain Auxiliary Building pressure within limits and the non-safety related Annulus Vacuum system automatically restored annulus pressure.
"The Shield Building ensures that the release of radioactive material from the containment atmosphere is restricted to those leakage paths and associated leakage rates assumed in the accident analysis during a LOCA. The EGTS system [Emergency Gas Treatment System] would have automatically started and performed it's design function to maintain Annulus Vacuum within required values.
"This event is being reported pursuant to 10 CFR 50.72(b)(3)(v)(D).
