60-DAY OPTIONAL TELEPHONIC NOTIFICATION FOR AN INVALID CONTAINMENT VENT ISOLATION ACTUATION
"This 60-day telephone notification is being submitted in accordance with paragraphs 10 CFR 50.73(a)(1) and 50.73(a)(2)(iv)(A) to report an invalid Containment Vent Isolation (CVI) actuation at Watts Bar Nuclear Plant (WBN) Unit 2.
"On April 14, 2016 at 1344 Eastern Daylight Times (EDT), Unit 2 technicians performing calibration checks on the Auxiliary Building general supply fan, connected test equipment to the wrong intake temperature switch, causing an invalid train B auxiliary building isolation (ABI) signal in both Unit 1 and Unit 2.
"Because the Unit 2 containment purge system was, at that time, configured in the 'refuel' mode, the invalid train B ABI concurrently initiated a train B CVI in WBN Unit 2. Consequently, the train B CVI caused the Unit 2 containment lower compartment radiation monitor to trip and control room operators entered Technical Specification Limiting Condition for Operation (LCO) 3.4.15 RCS Leakage Detection Instrumentation at 1344 EDT.
"By 1422 EDT, Unit 2 control room personnel had reset the containment purge system and by 1854 EDT had completed procedural steps to restore auxiliary building ventilation to its normal alignment. By 1858 EDT, Unit 2 control room personnel had completed the procedural steps to restore the containment purge system.
"During this event, the train B ABI and CVI actuations were complete and equipment functioned as designed. Upon identification of the train B ABI/CVI condition, the calibration activities were halted and a prompt investigation was initiated. WBN evaluators determined the apparent cause of the event was incorrect work instructions, with a contributing cause that technicians failed to use human performance error prevention tools to ensure they were calibrating the correct equipment. Personnel responsible for performing the calibration checks have been coached and corrective actions have been taken to correct the work instructions."
The licensee notified the NRC Resident Inspector.

AGREEMENT STATE REPORT - THEFT AND RECOVERY OF A PORTABLE GAUGE
The following information was received by email:
"On 4/13/16 CPN Model MC Series gauge was left in marked licensee vehicle parked outside technician's home in Columbus at end of work day, reportedly properly secured in vehicle with two independent locking devices. Gauge contains 10 mCi Cs-137 and 50 mCi Am-241:Be sources.
"Technician found gauge missing when came out to go to work on 4/14/16. Technician claims RSO was notified, RSO does not recall. No police report was filed and no report was made to ODH [Ohio Department of Health] at that time.
"On 5/10/16, gauge was found in vacant lot during separate police investigation. Police called fire department HAZMAT unit. Transport case was not locked, but gauge rod was locked. Licensee was identified by paperwork in the transport case. Licensee was contacted by fire department to retrieve gauge. Licensee RSO took possession of gauge and returned it to office in Columbus.
"On 5/11/16 licensee reported theft and recovery of gauge to ODH. ODH investigators visited site to determine cause of incident and reasons for lack of notifications."
Ohio Item Number: OH160003
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 - SHUTTER FAILURE ON A FIXED GAUGE
The following information was obtained from the State of Washington via email:
"[The Washington Department of Health - Office of Radiation Protection] investigation continues on the Kay Ray Sensall fixed gauge shutter failure. The licensee identified, during a routine shutdown, that the handle moves on the fixed gauge but fails to open and close the shutter. The licensee reported they believe the problem is a drift pin that allows the handle to turn the shaft of the shutter to its open/close position. The shutter is in the open position and is unable to be closed. The gauge is operating normally and correctly otherwise [and is] correctly mounted."
The gauge is a Kay Ray Sensall model number 7063S with serial number S94J2306.
