AGREEMENT STATE REPORT - DAMAGED MOISTURE-DENSITY GAUGE
The following was received from the State of Texas via email.
"On July 23, 2018, the licensee reported that one of its Troxler model 3430 moisture/density gauges (SN: 68529) had been run over and damaged by a dozer at a temporary job site. The licensee's technician was performing a moisture test when he saw a dozer moving backward into the area and toward the gauge. The technician yelled at the dozer driver but was unable to get his attention and there was not enough time for the technician to move the gauge. The gauge was severely damaged. The 40 milliCurie americium-241/beryllium source (SN: 47-21269) remained secure in its shielding. The source insertion rod was bent and broken and the 8 milliCurie cesium-137 source, which was still attached to the rod, could not be retracted. The licensee wrapped the exposed cesium source in lead blankets and placed the gauge back into its transport case. The area and dozer tracks were surveyed--there were no readings above background. The exterior of the transport case was surveyed and the highest reading was 0.4 mR/hr at the blanketed source. The damaged gauge was transported to the manufacturer's service center where a technician made the determination it was not repairable. The licensee is storing the gauge at its facility until arrangements can be made for disposal. An investigation into this event is ongoing. More information will be provided as it becomes available in accordance with SA-300."

UNPLANNED LOSS OF STEAM LINE MONITOR CHANNELS
"The following event description is based on information currently available. If through subsequent reviews of this event additional information is identified that is pertinent to this event or alters the information being provided at this time, a follow-up notification will be made via the ENS [Emergency Notification System] or under the reporting requirements of 10CFR50.73.
"This event is being reported pursuant to 10CFR50.72(b)(3)(xiii) as a Loss of Emergency Preparedness Capabilities at Palo Verde Nuclear Generating Station (PVNGS) Unit 2. On July 23, 2018, at approximately 1631 Mountain Standard Time (MST), the Unit 2 control room experienced an unplanned loss of Steam Generator #1 steam line monitor (RU-139), channels A and B.
"This monitor is used to assess dose projections for Main Steam line exhaust while in Modes 1-4 and is used in the PVNGS Emergency Plan to perform classification of Initiating Conditions 'RS1' and' RG1' and Emergency Action Levels (EALs) 'RS1.2' and 'RG1.2'. The PVNGS Emergency Plan does have two additional EALs that can be assessed for each Initiating Condition. The loss of this monitor constitutes a reportable loss of emergency assessment capability.
"The NRC Resident Inspector has been informed of this condition."

AGREEMENT STATE REPORT - RADIOGRAPHY CAMERA MALFUNCTION
The following report was received via e-mail:
"At approximately [2000 hrs. CDT] last night (July 23) a crew working at the DBI, Inc. facility in Tulsa had a casting they were shooting fall on the guide tube, crushing it, so that the source (28 Ci of Ir-192) could not be retracted. The RSO [Radiation Safety Officer] was notified and responded to the scene. DBI is licensed to perform source recoveries which they successfully did. As far as we [Oklahoma Department of Environmental Quality] know right now, there were no over-exposures as a result of this incident. [The state of Oklahoma] will provide details on the equipment involved when we have them."
