EN Revision Text: BOTH TRAINS OF LOW PRESSURE COOLANT INJECTION (LPCI) INOP
The following information was provided by the licensee via fax:
"At 1359 CDT on May 10, 2022, the 1B LPCI Loop Upstream Injection valve (1-1001-28B) was found to have a motor operated torque switch issue and inadequate lubrication. This issue called into question the ability of the valve to close when required.
"At 1746 CDT on May 10, 2022, both trains of Unit 1 LPCI were made simultaneously inoperable. TS 3.6.1.3 Condition A required de-activation of 1B LPCI Loop Downstream Injection valve (1-1001-29B) which was completed at 1746 CDT. Because of the de-activation of the 1B LPCI Loop downstream injection valve and LPCI Loop select logic, both trains of LPCI were made inoperable. Due to this inoperability, the system was in a condition that could have prevented the fulfillment of a safety function; therefore, this condition is being reported as an eight-hour, non-emergency notification per 10 CFR 50.72(b)(3)(V). Unit 1 HPCI and both loops of Core Spray are operable. After further engineering review, it was determined that 1B LPCI Loop Upstream injection valve condition was minor in nature and would not have affected the ability of the valve to close when required.
"There was no impact on the health and safety of the public or plant personnel. The NRC Resident Inspector has been notified."

The following information was provided by the licensee via phone call and email:
The last sentence in the second paragraph, "After further engineering review, it was determined that 1B LPCI Loop Upstream injection valve condition was minor in nature and would not have affected the ability of the valve to close when required," has been deleted. The licensee is continuing to follow up on the issue and believes that sentence to be unclear and premature.

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.
