AGREEMENT STATE REPORT - MISSING TRITIUM (H-3) EXIT SIGN

The following was received from the State of Utah via email:

"On July 19, 2016, the licensee [University of Utah] was performing a 6-month inventory of the H-3 exit signs, when the individual performing the inventory noticed that one of the signs was missing. The licensee left a message with the University's facilities management office to see if the sign was removed by them. On August 4, 2016, the licensee was informed by the [facilities] management group that they had not removed the sign. The licensee then determined that the sign was missing and presumed stolen. The licensee notified the DWMRC [Division of Waste Management and Radiation Control] of the missing sign on August 9, 2016. The licensee will continue to investigate the incident, and will submit a written report to the DWMRC. The DWMRC will possibly perform an investigation on August 10, 2016.

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 - DAMAGED MOISTURE DENSITY GAUGE

The following was received from the Commonwealth of Pennsylvania via email:

"On August 10, 2016, the Department [Pennsylvania Bureau of Radiation Protection] was notified by Testing Services, Inc. that a moisture/density gauge had been damaged while on location at a temporary job site. It is reportable per 10 CFR 30.50(b)(2).

"While at a temporary job site, a Humboldt Model 5001 gauge was damaged and became unusable after being run over by a compactor. A survey of the gauge indicated that the source was still in its shielded position. A leak test sample has been taken and sent for analysis and the gauge has been removed from service and secured. No over exposures have occurred. A service provider has been contacted to see if repairs are possible or if the gauge will be returned to the manufacturer.

"Radionuclides: Cs-137 and Am-241:Be
Manufacturer: Humboldt
Model: 5001
Serial Number: 2394
Activity: 11 mCi Cs-137, 44 mCi Am-241:Be

"The gauge has been securely stored and placed out of service until repairs/return can be accomplished. The Department has scheduled a reactive inspection. More information will be provided when available."

AGREEMENT STATE REPORT - FIXED NUCLEAR GAUGE STUCK SHUTTER

The following was received from the State of Texas via email:

"On August 10, 2016, The Agency [Texas Department of State Health Services] was notified by the licensee that during a daily inspection, the shutter on an Ohmart Vega SH-F1 nuclear gauge could not be operated. The gauge contains a 10 millicurie (original activity) source. The shutter is operated by an pneumatic operator. The operating mechanism is located inside a steel box to help prevent foreign material from interfering with the shutter operation. It appears that over time, moisture was being trapped in the box causing the operating rod connecting pin to rust and break. The shutter cannot be moved. It is in the open position which is the normal operating position for the shutter. A service company has been contacted and will be on-site on August 11, 2016, to repair the gauge. The gauge does not present an exposure hazard to the licensee's workers or members of the general public. Addition information will be provided as it is received in accordance with SA-300."

AGREEMENT STATE REPORT - STOLEN CHECK SOURCES

The following was received from the State of California via email:

"On July 28, 2016, [the Radiation Safety Officer] RSO at CB&I contacted RHB [Radiologic Health Branch] to report an incident on stolen check sources from their storage location at Hunters Point in San Francisco, CA. Theft occurred in the afternoon of July 26, 2016, between approximately 1330-1400 hours, while CB&I personnel were conducting business in adjacent project trailers. Items stolen included tools, equipment and locked posted radioactive check source safe. No other radioactive materials were stored inside this trailer.

"Source description is as follows:

OFFSITE NOTIFICATION

"On 8/12/16 at 1356 CDT, an ISFSI security officer noticed that two male children were walking west on the railroad tracks on the south end of the OCA, approximately 50 yards onto the property. The children appeared to be between 7 and 10 years of age. The children, presumably upon noticing Security's presence, then ran northeast and back towards the beach fence line. It appeared that the children somehow left the property through the east fence line back onto the beach. Industrial Security and shift RP tech began vehicle and foot patrols to search for the children and ensure that they did, in fact, leave the property. The children were not seen again.

"In accordance with 49 CFR 1580.105 - Reporting Significant Security Concerns, at 1520 on 8/15/16, the Radioactive Waste Group supervisor contacted the designated Transportation Safety Administration inspector to discuss the trespassing incident from 8/12/16. After the discussion with the inspector, the Radwaste supervisor was informed to contact the Department of Homeland Security Freedom Center and provide details of the incident. This contact was made at 1540 on 8/15/16.

"The notification is being made in accordance with 10 CFR 50.72(b)(2)(xi) notification to offsite government agency."

The licensee has notified the NRC Resident Inspector.

UNANALYZED CONDITION DUE TO NOT MEETING SINGLE FAILURE CRITERIA

"At 1722 [EDT] on 8/17/16, a Past Operability Evaluation (POE) determined the configuration of the Emergency Gas Treatment System (EGTS) flow controllers that existed prior to 0420 on 8/6/16 constituted an Unanalyzed Condition due to not meeting single failure criteria. This POE examined the condition where EGTS may auto-swap from the flow control path in A-Auto to the Standby flow control path upon the start of a Design Basis Event (DBE). The intended design of the EGTS swap over flow control path in Auto to Standby was to detect and respond to an actual failure of the A-Auto flow control path. The unnecessary auto-swap to Standby could prevent the EGTS train configured in Auto from performing its required safety function during a DBE. The POE performed a detailed calculation to determine the release effects due to the failure of the redundant trains of EGTS controllers. These calculations concluded that failure of both trains of EGTS controllers would not result in exceeding the 10CFR100 limits, however this condition was unanalyzed and failed to meet single failure criteria.

"This condition is reportable under 10CFR50.72(b)(3)(ii)(B), Unanalyzed Condition due to a system required to meet the single failure criterion does not do so.

"This condition had no impact to the health and safety of the public.

"The NRC Resident Inspector has been notified."

OFFSITE POWER SOURCE BELOW THE OPERABILITY LIMIT

"At 1826 [CDT], Operators identified that off-site 161 kV power source predicted post-trip voltage was below the operability limit of 161.3 kV. [Operators] entered AOP-31, 161 kV Grid Malfunctions, Section 1, 161 kV Grid Instability, and declared House Service Transformers T1A-3 and T1A-4 inoperable. [Operators] entered Technical Specification 2.7(2)c. Per Technical Specification 2.7(2)c, 'Both house service transformers T1A-3 and T1A-4 (4.16kV) may be inoperable for up to 72 hours. The loss of the 161kV incoming line renders both transformers inoperable. The NRC Operations Center shall be notified by telephone within 4 hours after inoperability of both transformers.'

"Per OPPD [Omaha Public Power District] Transmission, grid conditions are currently stable. OPPD Transmission has successfully raised predicted post-trip 161 kV voltage with all predicted voltages meeting or exceeding operability requirement of 161.3 kV as of 1834. Current post-trip predicted voltage is 162.2 kV as of 2029.

"Lowest observed actual voltage was 163.7 kV. The 161 kV line and transformers T1A-3 and T1A-4 remained available at all times."

The licensee notified the NRC Resident Inspector.
