AGREEMENT STATE REPORT - MISSING SOURCE ROD SHUTTER

The following report from the Arizona Department of Health Services (Department) was received by email:

"On August 18, 2020, during a routine inspection, the Department discovered that a licensee was in possession of a portable gauge which appeared to be missing its Cs-137 source rod shutter. The gauge was a Troxler Model 3430, Serial# 38482, containing 8 milliCuries of Cesium-137 and 40 milliCuries of Americium-241/Beryllium. While performing a survey of the gauge, inspectors recorded an exposure rate of 175 mR/hr over the shutter opening while the handle was in its locked position.

"The Department has requested additional information and continues to investigate the event."

EN Revision Text: AGREEMENT STATE REPORT - LEAKING CHECK SOURCE

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

"Framatome notified the State of Washington of a leaking 5 microCi Cs-137 check source that was identified on 8/17/2020. A set of stack samples showed evidence of Cs-137 contamination, leading the Radiation Safety Officer for the licensee to contact the Radiological Safety Supervisor to investigate into the possibility of a leaking Cs-137 check source. A visibly damaged source was identified and a leak test of the source revealed 0.02 microCi of removable material. The source storage area was surveyed to determine if there was any additional contamination, but none above the licensee's limits for action was identified. The source was contained and placed in storage to be held for disposal."

Washington Incident No.: WA-20-017

* * * UPDATE ON AUGUST 26, 2020 AT 1250 EDT FROM ANDREW HALLORAN TO BRIAN LIN * * *

The following information was received from the State of Washington via email:

"The leak test was performed in accordance with approved procedures using an instrument that was appropriate and in calibration. The source was part of a source jig used for routine instrument checks around the site. According to the Radiation Safety Officer, the source was likely damaged from impact against a hard surface during routine use."

AGREEMENT STATE REPORT - TWO LOST SOURCES

The following is a summary of information received via email:

On August 24, 2020, the licensee notified the New Jersey Department of Environmental Protection of two lost sealed sources. The sources had been sent from the licensee's Austin, Texas facility to their Fair Lawn, New Jersey facility, and are reported as missing by the shipper. The two sources were Ni-63 foil sources with an activity of 10 mCi each (S/N: AO-2484 and AO-5478). Each source was in a Life Technology Holdings, model Trace 1300, electron capture detector (S/N: 719420216 and 719420261).

The shipper has been searching for the sources, but at this time considers them missing with little likelihood of recovery. The shipper's tracking system indicates that the sources were delivered to the licensee's Fair Lawn facility, but that location has stated they never received the sources. The address to which the sources were reportedly delivered does not exist and the person who reportedly signed for the package is unknown to the licensee.

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 - NUCLEAR GAUGE SHUTTER STUCK OPEN

The following information was received from the Texas Department of State Health Services (the Agency) via email:

"On August 25, 2020, the Agency was notified by the licensee's consultant that during routine inspections the shutter on a Vega model SHGL-1 nuclear gauge containing a 2,000 milliCurie (original activity) cesium-137 source was stuck in the open position. Open is the normal position for the shutter. The gauge does not create an exposure hazard to any individual. The licensee's service provider is aware of the failure. Additional information will be provided as it is received in accordance with SA-300."

AGREEMENT STATE REPORT - SOURCE POTENTIALLY DAMAGED BY FIRE

The following information was received by the state of California via email:

"On 08/25/20, the California Office of Emergency Services contacted the Radiologic Health Branch (RHB) to report potential fire damage to a moisture gauge stored inside a barn located in Napa County, CA. The gauge involved is a CPN International, Inc. Model 503, moisture gauge containing 50 milliCuries of Am-241:Be.

"The Radiation Safety Officer (RSO) hasn't been to the incident location, however, he confirmed that the barn where the gauge was stored and the adjacent house have been burned down during the wildfire. The gauge is presumed to have been damaged by the fire; however, due to high temperature resistant construction of the source, the source integrity may not have been affected. According to the RSO, the property is located in a remote area in Napa County, and the entrance to the property is secured by two locked metal gates. Access by the general public is not anticipated. The RSO had already contacted the vendor, Instrotek for disposal of the damaged gauge. The RHB will be coordinating with Instrotek and intends to accompany Isotek if Isotek goes to the site. The United States Environmental Protection Agency has also been informed, and it is possible they may be involved in the gauge recovery."

PART 21 REPORT - FAILURE OF MAIN STEAM ISOLATION VALVE AIR PACKS

The following is a synopsis of information received from the licensee:

On March 6, 2020, while at zero percent power and in Cold Shutdown - Mode 4, Nine Mile Point Unit 2 (NMP2) determined through surveillance testing that three Main Steam Isolation Valves (MSIVs) did not meet their Technical Specification closure time.

The cause of the MSIV failures has been determined to be delayed Air Pack response. The delay was caused by a buildup of corrosion product and waxy foreign material believed to be dried pipe thread sealant or O-ring assembly lube that accumulated on the internal surfaces of the Air Pack during refurbishment by the vendor Trillium (previously Hiller).

The following is action taken or planned to be taken to prevent recurrence: A note will be added to the procurement requirement evaluation form and purchase order for MSIV Air Pack refurbishments to minimize use of O-ring lubricant and thread sealant to limit likelihood of capturing foreign material on Air Pack valve internals.

The Energy Industry Identification System (EIIS) component function identifier and system name of each component or system referred to above is:
Component - Main Steam Isolation Valves, Air Pack.
IEEE 803 Function Identifier - VOP.
IEEE805 System Identification - SB.

The licensee notified the NRC Resident Inspector.
