AGREEMENT STATE REPORT - SHUTTER ON DENSITY GAUGE

The following information was provided by the State of Arkansas via email:

"On September 23, 2016 at 1300 CDT, the licensee contacted the Department [Arkansas Department of Health] reporting that during operations on September 22, 2016, the licensee discovered that the shutter on a Vega Americas Model BAL density gauge would not open. The gauge contains 300 milliCuries of Krypton-85.

"The gauge was replaced with a spare gauge and has been placed in a secure storage area and radiation exposure is maintained at less than 2 mR/hr.

"The licensee is contacting the manufacturer to request repair or disposal of the gauge.

"In accordance with RH-1502.f.2 (10 CFR 30.50(b)(2)) the malfunctioning shutter is reportable within 24 hours.

"The State of Arkansas is awaiting a written report from the licensee. The State's event number is AR-2016-011."

The shutter failed to open on September 22, 2016 and the gauge was removed from service and placed in storage. On November 28, 2017, the manufacturer took possession of the gauge for disposal.

"The Department considers this event to be CLOSED."

AGREEMENT STATE REPORT - PATIENT UNDERDOSAGE OF YTTRIUM-90

The following report was received from the California Department of Public Health via email:

"On September 23, 2016, the Radiation Safety Officer of the University of California, Los Angeles (UCLA), contacted the Brea office of the Radiologic Health Branch to report a medical event.

"A patient was treated with Nordion TheraSpheres containing yttrium-90 (Y-90) on September 22, 2016. The prescribed dose was 100 gray (Gy) to the left lobe of the liver. Upon completing the dose assessment after the treatment, it was discovered that only approximately 50 percent of the intended dosage of Y-90 was delivered to the patient (left lobe of the liver). The remainder of the Y-90 dosage appears to have remained in the delivery system, primarily in the system waste container. The licensee performed surveys to confirm that the areas surrounding the delivery system and patient were not contaminated.

"The patient has been notified, and the licensee is investigating to determine the cause of the event."

CA 5010 Number: 092316

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.

LOSS OF SECONDARY CONTAINMENT DIFFERENTIAL PRESSURE

"On September 22, 2016, at 0320 [EDT], Secondary Containment Zone 2 (Unit 2 Reactor Building) differential pressure lowered to 0.15 [inch] WG due to a stuck non-safety related exhaust damper on the in service Zone 2 exhaust fan. Required differential pressure per SR 3.6.4.1.1 could not be maintained. Zone 2 differential pressure recovered to greater than 0.25 [inch] WG on September 22, 2016 at 0342 [EDT] by starting the standby Zone 2 exhaust fan. Zone 1 (Unit 1 Reactor Building) and Zone 3 (Unit 1&2 Reactor Buildings) ventilation remained in service and stable.

"This event is being reported under 10 CFR 50.72(b)(3)(v)(C) and per the guidance of NUREG 1022 Rev 3 section 3.2.7 as a loss of a Safety Function. There is no redundant Susquehanna Secondary Containment System."

The Licensee notified the NRC Resident Inspector.
