EN Revision Text: AGREEMENT STATE REPORT - GROUNDWATER CONTAINING URANIUM IDENTIFIED DURING EXCAVATION
The following was received from the Utah Department of Environmental Quality via email:
"On April 18, 2022, Licensee personnel reported a strong fuel smell coming from a recent excavation associated with a new facility under construction. The excavations for sumps extended into the groundwater and were not included on the conditionally approved plans. The smell triggered an investigation where groundwater samples were collected for both chemical and radiological analysis. One sample indicated a concentration of 12,000 pCi/L of uranium (preliminary findings). The presence of uranium in the groundwater was unanticipated. Subsequently, the Division of Waste Management and Radiation Control has communicated to the licensee to characterize the nature and extent of the contamination. The Division is waiting for additional information from the licensee."

The following update was received from the Utah Department of Environmental Quality (the agency) via email:
"On April 18, 2022, [Licensee] personnel reported a strong fuel smell coming from a recent excavation associated with a new facility under construction. The [Licensee] did not anticipate encountering groundwater at the depth of excavation. Upon encountering the groundwater and observing a hydrocarbon odor, the Licensee collected groundwater samples for both organic and radiological analysis. The preliminary screening of one sample indicated a potentially high concentration of uranium. The preliminary result of the analysis was reported to the agency with the intent to conduct additional confirmatory work. The Licensee contends that the initial high concentrations were in error due to improper analytical methodology. These results were presented to the agency prior to confirmation. Results of further investigation by the Licensee indicate that the contaminant was thorium, not uranium, and that all radionuclides were below detection limits.
"The agency collected confirmatory samples for analysis and is awaiting results of both organic and radiological analysis.
"The Licensee is preparing an investigation plan to fully characterize the nature and extent of the contamination."

AUTOMATIC SCRAM DUE TO ELECTRICAL TRANSIENTS
The following information was provided by the licensee via fax:
"Unit 2 experienced multiple electrical transients resulting in a Group I Primary Containment Isolation Signal (PCIS) isolation and subsequent unit reactor scram. Low reactor water level during the automatic scram caused PCIS Group II and III isolation signals. Following the PCIS Group I isolation, all main steam lines isolated. All control rods inserted and all systems operated as designed."
The following additional information was obtained from the licensee via phone in accordance with Headquarters Operations Officers Report Guidance:
Peach Bottom Unit 2 automatically scrammed from 100 percent power due to an electrical transient and subsequent PCIS Group I isolation (Main Steam Isolation Valve closure). Unit 2 lost main feedwater due to the PCIS Group I isolation, however, all other systems responded as expected following the scram. High Pressure Coolant Injection is maintaining pressure control while Condensate Pumps are maintaining inventory. The unit is currently stable and in Mode 3. Peach Bottom Unit 3's Adjustable Speed Drives were impacted by the electrical transients and the unit reduced power to 98 percent power.
The NRC Resident Inspector was notified.

EN Revision Text: UNPLANNED CONTAMINATION EVENT
The following information was provided by the licensee via email:
"The plant is in a safe configuration. NRC Region II re-exited an inspection on April 26, 2022 from an inspection which was conducted March 21st through the 24th. During this exit, an event was reclassified as a Non-Cited Violation for failure to report an event. As a result, UUSA [Urenco-USA] is reporting this event as a 24-hour Report per the NRC's inspection.
"On February 28, 2022, water was discovered on the floor of the Liquid Effluent Collection and Transfer System (LECTS) room. The water was leaking from the slab tanks berm into the non-Radiological Controlled Area floor. The area was conservatively and promptly roped off and signage was posted. Radiological readings in the area were taken and found to be less than background and the the spill was cleaned up that day.
"Historical issues are being reviewed and will be added to this notification per the NRC's position shared with UUSA.
"This issue has been entered in UUSA's corrective action program as EV 149668 and 149975."

The following update was provided by the licensee via email:
"As a result of this Event Notification, a review of Extent of Condition was performed.
"This Extent of Condition revealed nine historical examples of unplanned contamination events that resulted in expansions of Contaminated Areas that were not reported under 10 CFR 70.50(b)(1) as required by regulation.
"These conditions occurred on March 3, 2016 (EV 111023), April 14, 2016 (EV 1129221), August 4, 2016 (EV 113877), December 7, 2016 (EV 116283), February 23, 2017 (EV 117238), November 24, 2019 (EV 136211), November 29, 2021 (EV 148894), February 28, 2022 (EV 149668), and April 14, 2022 (EV 151253).
"These events have been investigated and corrected during the approximate time period in which they were identified. No contamination events are ongoing at UUSA at this time."

AGREEMENT STATE REPORT - UNDERDOSE MEDICAL EVENT
The following information was received via e-mail:
"The City of Hope Radiation Safety Officer contacted LA County Radiation Management (LA County) on May 10, 2022 to report a Medical Event that occurred on the same day at City of Hope in Duarte, CA. The patient was underdosed during a Selective Internal Radiation Therapy (SIRT) treatment for liver cancer that involved the administration of SIR-Spheres yttrium-90 (Y-90) resin microspheres. The prescribed dose to the patient was 10 mCi, but the dose delivered to the patient was only 6.42 mCi due to a leakage caused by a loose tubing connection.
"City of Hope will conduct an investigation to gain a better understanding of the details of the event."
California 5010 Number: 051022
A Medical Event may indicate potential problems in a medical facility's use of radioactive materials. It does not necessarily result in harm to the patient.
