AGREEMENT STATE REPORT - NUCLEAR PHARMACIST RECEIVES GREATER THAN 50 REM EFFECTIVE DOSE EQUIVALENT

The following report was received from the Oregon Department of Health via facsimile:

"Oregon Health Authority, Radiation Protection Services (RPS) has confirmed on 11/07/16 that a cumulative effective dose equivalent of 50 rem [received by] a pharmacist working in several facilities. This information is being reported by PETNET Solution's corporate office in Knoxville, TN.

"Oregon Health Authority, Radiation Protection Services (RPS) received a call on October 20, 2016 at 1348 [PDT] informing the office that a contract pharmacist may have received an exposure greater than 50 rem to [the] right ring dosimeter and is conducting an analysis to determine if the individual received a dose greater than 50 rem. [The] caller is [the], Corporate Radiation Safety Officer (CRSO), PETNET Solutions.

"It's suspected that the individual received multiple doses while working at PetNet's Phoenix, Arizona and Portland, Oregon pharmacies. Dosimetry rings from both sites demonstrate a possible cumulative dose greater than 50 rem. The individual has now been restricted from working with radiopharmaceuticals at this time.

"CRSO states that the incident was discovered on 10/19/2016 and as of 11/07/16, exposure levels of greater than 50 rem are confirmed. This notification involves two facilities in Arizona and Oregon and RPS is not sure if the HOO [NRC Headquarters Operations Officer] was contacted by other regulatory agencies.

"CRSO has commenced a root cause analysis of the incident with an estimated date for completion within approximately two weeks."

Oregon Incident Number: 16-0037

AGREEMENT STATE REPORT - RADIOGRAPHY CAMERA SOURCE DISCONNECT

The following was received from the State of Colorado via email:

"The radiography source disconnect occurred on 10/19/2016 at a metal fab yard in Berthoud, CO. No members of the public are believed to have been exposed to radiation from the incident at this time. The source isotope was Ir-192 with an activity of 40 Ci. The source was successfully retrieved by the licensee. The licensee reported the following dose estimates for those involved in the incident.

"Radiation Safety Officer: 50 mR
"Radiographer: 28 mR

Event Report ID No.: CO16-I16-23

SAFETY INJECTION PIPING WELD FLAW

"While performing a scheduled inservice inspection on a section of safety injection system piping, a flaw was identified in a circumferential weld on the 14 inch safety injection line from the 2A safety injection tank to the 2A reactor coolant loop. Examination results indicate that the flaw constitutes a welding defect that cannot be found acceptable under ASME Section XI, IWB-3600, or Table IWB-3410-1. Further analysis is being conducted.

"The unit had been shutdown for its 19th refueling outage (3R19) on October 8, 2016, at 0000.

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

This piping is required to be operable in modes one through four.

* * * RETRACTION ON 11/10/16 AT 1640 EST FROM ROBERT CHU TO MARK ABRAMOVITZ * * *

"Subsequent engineering examination of the weld on the 14" safety injection line from the 2A safety injection tank to the 2A reactor coolant loop using enhanced examination techniques concluded the indication in the circumferential weld does not represent a flaw constituting a weld defect. The indication was the result of a metallurgical weld interface in the area of a previously documented weld repair. Therefore, the indication is acceptable under ASME Section XI with no further analysis required.

"Based on the above information, PVNGS has determined the indication does not represent a degraded condition of a principal safety barrier as defined by 10CFR 50.72(b)(3)(ii)(A) and event notification #52309 is retracted.

"The NRC Resident Inspectors have been notified."
