EN Revision Text: AGREEMENT STATE REPORT - NUCLEAR GAUGE ENGULFED DURING FIRE

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

"On August 21, 2020, at 1307 CDT the Agency was notified by the licensee consultant (LC) that a fire was burning on one of its dredges off the coast Corpus Christi, Texas. The LC stated the drudge had a 250 milliCurie (original activity) [Cs-137] source in a Berthold model 7440 nuclear gauge installed on a pipe for density measurement. The LC did not have any other information on the location, but knew the dredge was in between 40 and 50 feet of water. The LC stated that the personnel on board were fighting the fire. The LC stated they believed that the gauge would be engulfed by the fire. The LC stated they would supply additional information once the fire is out and they have a chance to inspect the equipment.

"At 1553 CDT the LC contacted the Agency and stated the dredge workers were able to take dose rate reading about two feet from the gauge and the reading was 26 millirem per hour. The LC stated that the steel was still too hot to stay very long in the area. The LC stated (when asked) that they believe the fire is out. The LC stated the current priority on the drudge was locating several missing individuals. The LC stated they directed personnel on the drudge to take a contamination survey on the gauge as soon as possible. The LC stated the gauge source serial number was 0025-06.

"A search of news sources in Corpus Christi, Texas by the Agency found that a barge had struck an underwater natural gas line at a facility in Corpus Christy, Texas. This information was verified by the licensee's LC. The news reports stated the event occurred at about 0800 CDT. The report stated that the Texas Division of Emergency Management and Texas Department of Public Safety personnel are on the ground to provide support, and the Texas Commission on Environmental Quality is monitoring air quality in the area. The United States Coast Guard is assisting in the fire fighting and search for individuals. The name of the dredge involved was provided in several reports. The Agency contacted the LC verified the ship was owned by the licensee. This information was verified by the Agency by reviewing four different news sources.

"Additional information will be provided as it is received in accordance with SA-300."

AGREEMENT STATE REPORT - INCORRECT DOSE DELIVERED TO PATIENT

The following was received from the Ohio Department of Health:

"The licensee tried to perform a split dose procedure on the right lobe anterior and right lobe posterior portion of a patient's liver.

"The prescribed dose was 60 mCi Y-90 Theraspheres (approximately 150 Gy) for each site. The posterior was treated first and then the catheter was moved to the anterior position. Post treatment scans of the patient indicated the posterior received 20 mCi (35 Gy) and the anterior received 100 mCi (180 Gy). The physician believes the catheter slipped after initial placement, resulting in an overdose to the anterior and underdose to the posterior.

"The licensee will no longer conduct spilt dose procedures."

AGREEMENT STATE REPORT - LOST TRITIUM EXIT SIGNS

This is information received from the state of Nebraska via email:

"In conducting a search for records for NRC Event #54500, it was determined that Home Depot #3210 was remodeled at the same time as Home Depot #3208 in Grand Island, NE and all (16) tritium exit signs were exchanged for LED in May 2012. Disposal records are unavailable due to Staybright Electric, the contractor in charge of replacement and disposal, going out of business. Home Depot was unable to produce disposal records but it is there belief that the signs were disposed of properly as Staybright conducted tritium exit sign removals for other Home Depots in the region prior to their closing for which records of disposal were obtained, demonstrating knowledge of proper procedure.

"The State of Nebraska also checked with Tritiumdisposal.com and SRBT in attempt to locate records as the outlets of disposal for Staybright, but no records were found.

"Home Depot currently has a plan in place that was submitted to the NRC in July of 2009 for facility management to reiterate tritium exit sign management requirements to existing vendors to ensure signs are managed within NRC requirements. As part of ongoing tritium exit sign servicing it is very reasonable to believe that Staybright transferred and disposed of tritium exit sign inventory properly. Home Depot continues to proactively address and replace (as appropriate) its remaining tritium exit sign inventories through the use of professional, third party vendors and continues to responsibly manage its existing inventories at current stores throughout the United States.

"A Home Depot corporate representative will track all purchases and returned signs to ensure accurate inventory and disposal.

"All Tritium Exit Signs have been replaced with LED.

"Home Depot will no longer install tritium exit signs within newly constructed locations."

AGREEMENT STATE REPORT - LOSS OF MEDICAL SEED AFTER REMOVAL FROM PATIENT

The following is a synopsis of the event received from the Georgia Radioactive Materials Program:

On July 31, 2020, a physician did not follow proper procedure while recording the number of seeds administered to a patient. The physician initially planned on administering one seed but decided to administer two. The physician did remove both seeds from the patient on August 3, 2020. The tracking system for the administered seeds was based on writing the number of seeds administered on a colored bracelet or arm band, which the patient wears while the seed(s) are implanted. It is removed and travels with the removed tissue through the remaining processes at the hospital. In this case, the physician did not revise the number on the bracelet, therefore during the subsequent processes, other hospital staff only looked for one seed to recover from the procedure by-products. One seed was not recovered. There was some discussion between departments prior to August 21, 2020 about the seed. Radiation Safety was not contacted.

On August 21, 2020, an Assistant RSO discovered the discrepancy while conducting an inventory, preparing the seeds for return to the seed vendor. Subsequent searches that included the involved staff did not recover the missing seed. After a review of the laboratory processes for analyzing the removed tissue, the hospital staff believes the missing seed was retained in the transport bin and disposed of with that bin in the bio-hazard waste stream. But, this can not be proven. It was demonstrated to not be in the frozen sample that the hospital retained. The hospital declared the seed lost on August 27, 2020.

The seeds were I-125 encapsulated in titanium. Model IAI-125A. Activity level calculated to be 145.1 microCuries at time of loss/disposal. The radioactivity is small, and the decay rate high such that this poses a low risk to the public. Based on literature, the RSO states the contact dose, assuming the seed was trapped in clothing (contact) for twelve hours to be 2.66 milliSeverts.

The hospital has conducted a root cause analysis, and has revised its procedures and re-trained staff to prelude future loss of radioactive seeds.

AGREEMENT STATE REPORT - MEDICAL EVENT - UNDERDOSE

The following was received from the Georgia Radioactive Materials Program via email:

"At the end of the administration of Y-90 SIR Spheres [for the treatment of tumors in the right lobe of the liver], the delivery vial (D-Vial) appeared to overfill as the radiologist was attempting to mix the spheres with a 50/50 solution of contrast and 5 percent dextrose/glucose (D5W). The radiologist noticed some clumping and after attempting to gently disperse the Spheres, he gave a couple hard pushes of the contrast/D5W into the D-Vial. At that time, he noticed the leak. He examined the septum and found it to be dry. As a precaution the radiologist put Durabond on top of the septum. Further examination showed that the material leaked out of the sides of the crimped vial top rather than the septum. The procedure was stopped to prevent further contamination.

"The event occurred while using SIRTEX new SIROS delivery system. The SIRTEX representative was present providing guidance to the radiologist as this was the first time he used the new system.

"It is estimated that 75 percent of Y-90 SIR-Spheres were administered to the patient [Prescribed Activity: 3.1 GBq (83.7 mCi); Delivered Activity (estimated): 2.87 Gbq (77.7 mCi)]. It is likely that the residual activity was over estimated due to contamination of the SIROS delivery dome. The usual waste from the procedure is contained in a 1-liter Nalgene containers and then placed in a Lucite shield for dose rate measurements to determine the residual activity. The Siros delivery dome could not be measured in the same geometry and likely resulted in an increased dose rate and underestimate of the total dose delivered.

"At this time, the prescribing physician indicated he does not expect any adverse effects for the patient and is awaiting the dosimetry evaluation from the patients PET/CT Scan.

"Attempts have been made to recreate the event without success. There is speculation regarding the size of the dose and that the number of Spheres may have been a factor (larger than typically administered). Representatives from SIRTEX indicate that this has not been an issue at other sites.

"Prior and subsequent studies with the new SIROS delivery system were successful with less activity.

"Further evaluation of the equipment to determine why the vial leaked, will be performed following decay and return the manufacturer."

DAMAGED GAUGE DUE TO VEHICLE INCIDENT

The following was received via email from the licensee:

"[The Engineering Technician] was performing density tests on an aggregate base with a nuclear density gauge (nuc) [gauge: Troxler 3411 s/n 14468; 8.0 mCi Cs-137; 40.0 mCi Am-241] and the loader operator was also working in the area. The [loader] operator was trying to back-up and grazed [the Engineering Technician] on his left shoulder slightly with the rear bumper end, just after [the Engineering Technician] had brought the source rod into the safe position to record the test results. [The Engineering Technician] rolled out of the way and as the loader came to a stop it had hit the nuc gauge and broke the guide rod. Unsure if the source was intact, [the Engineering Technician] kept the loader in-place and kept people more than 15 feet away until [the Operations Manager and the Senior Project Consultant] could arrive on-site to assess the situation. [The Engineering Technician] informed [the Operations Manager and the Senior Project Consultant] on the phone and once they arrived on-site that he was uninjured, since he was able to easily roll out of the way of the loader. [The licensee] then determined that both sources were still intact and the source tip was in the shielded position within the gauge. [The licensee] took a Geiger Counter reading at the site (0.06 mRem/hr 3 feet from the gauge) and again after loading the gauge into the transport box (less than 0.03 mRem/hr 3 feet from the box). Prior to loading the gauge into the box, [the licensee] performed a leak test on the gauge and shipped the leak test to Instrotek as soon as [the licensee] returned to the office with the damaged gauge."

The licensee noted that the gauge is currently locked-out/tagged-out and once they receive the leak test results they will most likely transfer the gauge to Instrotek for disposal.

AGREEMENT STATE REPORT - POOL WATER CONDUCTIVITY EXCEEDED LIMITS

The following was received from the State of California Department of Public Health - Radiologic Health Branch (CDPH/RHB) via email:

"The licensee Radiation Safety Officer reported that the pool water conductivity exceeded 100 microSiemens/cm on 9/3/20. The reason was the loss of operability of the demineralizer pump. The pump has been repaired and is currently operable with declining pool water conductivity, but the pool water is still in excess of 100 microSiemens/cm. CDPH/RHB is continuing to investigate the circumstances surrounding this event."

AGREEMENT STATE REPORT - GAUGE DAMAGED WHEN STRUCK BY VEHICLE

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

"On September 5, 2020, The Agency was notified by the licensee's site radiation safety officer (SRSO) that a Humboldt EZ 5001 moisture/density gauge was damaged at a temporary job site when a bulldozer struck the gauge. The gauge contains a 40 milliCurie americium-241 source and a 10 milliCurie cesium-137 source. The cesium source was in the shielded position when the event occurred. The operating rod was bent, and the SRSO stated he did not believe the cesium source rod would move. The SRSO stated they performed radiation surveys around the gauge and the highest reading they obtained was 1.3 millirem per hour, which is a normal reading. The SRSO stated they were taking the gauge back to their storage location and would perform a leak test of the gauge. The event did not present an exposure risk to any individual. Additional information will be provided as it is received in accordance with SA-300."

LOSS OF EMERGENCY ASSESSMENT CAPABILITY

"At 1748 EDT on September 12, 2020, Unit 2 emergency core cooling system (ECCS) leakage outside containment was determined to exceed the long-term habitability dose analysis for the Catawba Nuclear Station Technical Support Center (TSC) under bounding conditions. Repair options to arrest the leakage and restore functionality of the TSC are currently being evaluated.

"If an emergency is declared requiring TSC activation during this period, the TSC will be staffed and activated using existing emergency planning procedures unless the TSC becomes uninhabitable. If relocation of the TSC becomes necessary, the Emergency Director will relocate the TSC staff to the alternate facility.

"This is an eight-hour, non-emergency notification for a loss of Emergency Assessment Capability. This event is reportable In accordance with 10 CFR 50.72(b)(3)(xiii) because the discovered condition of the TSC affects the functionality of an emergency response facility.

"There is no impact on the health and safety of the public or plant personnel. The NRC Resident Inspector has been notified."

This same condition was reported under EN #54887.
