MEDICAL EVENT - DOSE GIVEN TO INCORRECT SEGMENT OF THE LIVER

During a Y-90 TheraSphere treatment (hepatocellular carcinoma) to the right lobe of the liver segments 5, 6, 7, and 8 (estimated volume of 1290 ml), the catheter moved and the dose was actually given to medial segment 4 (estimated volume of 330 ml). The prescribed dose was 120 Gy (3.3 GBq) and the delivered dose was approximately 118.5 Gy as determined by bremmstrahlung imaging. Segment 4 was previously treated and there was some residual cancer at this location. This dose is not expected to have detrimental effects on the patient.

It is anticipated that segments 5,6,7,8 will be treated at some future time.

The patient has been notified and the prescribing physician will be notified.

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.

AGREEMENT STATE REPORT - EMPLOYEES POTENTIALLY EXPOSED TO RADIATION

The following was received via email from Arizona:

"On April 26th, the Agency [Arizona Radiation Regulatory Agency] was contacted by the licensee who indicated that seventeen employees had been exposed to ionizing radiation by a nuclear gauge while working on Crusher Number Three. The nuclear gauge was mounted on the shoot above the crusher. The workers involved worked in the area of concern from Saturday April 23rd until Tuesday April 26th, when the Radiation Safety Officer was notified of the incident.

"The gauge involved is used for level detection in the shoot and contains 150 millicuries of Cesium-137. Radiation levels in the work area have yet to be determined.

"The investigation into this event is ongoing.

"The U.S. NRC and Arizona Governor's office are being notified of this event."

Arizona Incident number 16-006.

HIGH PRESSURE SAFETY INJECTION VALVE BONNET LEAKAGE IDENTIFIED DURING REFUELING OUTAGE

"The following event description is based on information currently available. If through subsequent reviews of this event additional information is identified that is pertinent to this event or alters the information being provided at this time, a follow-up notification will be made via the ENS or under the reporting requirements of 10 CFR 50.73.

"At 0500 MST on May 5, 2016, engineering personnel determined that leakage from the bonnet seal weld of the Train B High Pressure Safety Injection (HPSI) system loop 2A injection valve, SIBUV0616, constituted reactor coolant system pressure boundary leakage. This is being reported as a degradation of a principal safety barrier pursuant to 10 CFR 50.72(b)(3)(ii)(A).

"The leak was identified during a planned activity in which Operations was filling the refueling pool using HPSI pump B. Leakage was stopped when a plant operator closed SIBUV0616.

"PVNGS Unit 1 was shut down for its 19th refueling outage (1R19) on April 9, 2016, at 0000 MST and is in Mode 6.

"The NRC Resident Inspectors have been informed of this condition."
