"At 1028 CDT today 3/25/2010, a rejectable void was found in one of the suction lines (cooled suction line) to the B HPSI [High Pressure Safety Injection] pump. The main suction line is water filled. The piping was declared inoperable and the appropriate technical specification was entered. At 1357 CDT the void was cleared from the cooled suction line and the piping was declared operable. Subsequently, at 1409 CDT a similar rejectable void was discovered in the other cooled suction line for HPSI pumps A and C. The piping was declared inoperable. The appropriate technical specification was entered. At 1447 CDT the void was cleared and the piping was declared operable. Due to the close proximity of these occurrences the station is conservatively reporting this as a safety system functional failure as it appears that both trains of HPSI cooled suction were inoperable at the same time."
The licensee notified the NRC Resident Inspector.
* * * RETRACTION FROM ERICK MATZKE TO VINCE KLCO ON 5/24/10 AT 1517 EDT * * *
"Subsequent to making this event notification a detailed analysis of the event was performed by FAUSKE / Westinghouse Engineering. This evaluation determined the quantity of gas voiding in the piping, the duration of time the pump(s) would be subjected to gas voiding and potential effects on the piping support design loading. The hydraulic data was then reviewed by the HPSI pump manufacturer (Sulzer) to determine the effect on pump performance. Based on these evaluations, it has been determined that the HPSI pumps were not degraded, and that they were capable of performing their design basis function at all times and were operable. Therefore, this event does not meet the 10 CFR 50.72 reporting criteria and the notification is being retracted."
The licensee notified the NRC Resident Inspector. Notified the R4DO (Shannon). |

| Event Text AGREEMENT STATE REPORT - STUCK RADIOGRAPHY CAMERA SOURCE
The following information was obtained from the State of North Dakota via email:
"T&K Inspections, Inc., reported the inability to retract a 3.55 TBq (96 Ci ) Ir-192 radiography source into the exposure device (Source Production & Equipment Company Model SPEC 150, serial number 295) on May 10, 2010. Operations were being performed approximately 2 miles south of Highway 2, on 94th street, south of Ross, ND about 9:00 am CDT.
"After completing the exposure, the radiographer and assistant radiographer performed the routine procedure to retract the source into the camera. The survey meter registered no activity above background, so they believed the source had retracted. As the radiographer approached the camera, the survey meter registered off-scale. He immediately stepped away from the camera and attempted to check the cable and retract the source. At this time, his pocket dosimeter registered 3mR/hr. With the survey meter continuing to register activity, the President and assistant RSO of T&K Inspections, Inc. was contacted. He suggested working with the crank and they were able to retract the source into the camera. The camera was located near the vehicle. As the radiography crew placed the camera onto the end gate of the truck, the survey meter and his pocket dosimeter were off-scale. They immediately moved away from the camera and called the assistant RSO again. The cables were still connected to the camera, so the assistant RSO had the radiographer straighten the cable and try to retract the source. The source was successfully retracted into the camera housing. The camera was secured in the vehicle and the crew returned to the shop.
"Prior to this incident, T&K Inspections, Inc. believed they had trouble with the lock mechanism on this camera. April 28, 2010, the camera was sent to SPEC for inspection and maintenance. Maintenance and inspection was performed on the camera May 3, 2010. SPEC replaced parts of the camera and returned it to T&K Inspection with a certification document. The camera was placed back into service and has been used prior to the incident. T&K Inspections, Inc. believes when the camera was returned to the vehicle the lock mechanism was not functioning properly.
"The assistant RSO has sent the film badges overnight delivery to be evaluated. The radiographer and assistant radiographer will not perform radiography until return of the dosimetry reports. The assistant RSO will follow-up with a report of the incident, copy of the camera certification, copy of the film badge reports and any other pertinent information as needed.
"The camera has been taken out of service and will be returned to SPEC. It will be determined if the camera or parts will be replaced."
Camera source information: "Ir-192 SPEC G-60 Source, S/N RE0304, 96 Ci
"State Action:
"1. The North Dakota Department of Health (NDDOH) will maintain contact with T&K Inspections, Inc. to determine the root cause of the incident.
"2. The NDDOH will receive a copy of the dosimetry reports and a copy of the certificate from SPEC from the camera maintenance and inspection that was performed prior to the incident.
"3. The NDDOH will follow-up with the camera inspection that will be performed at this time."
* * UPDATE FROM LOUISE ROEHRICH TO JOHN KNOKE AT 1547 EDT ON 5/20/10 * *
The radiographer and assistant radiographer received 1181 mRem and 756 mRem respectively.
Notified FSME (James Danna) and R4DO (Vivian Campbell)
* * * UPDATE ON 5/24/2010 AT 1100 FROM LOUISE ROEHRICH TO MARK ABRAMOVITZ * * *
The radiography camera was inspected in the field and the problem was replicated. The camera has been taken out of service, returned to the manufacturer for disposal, and replaced with a different camera. A calculation of the dose to the radiographer's hand estimated the dose at 12.3 REM. Analysis of the problem by the licensee revealed that procedures were not followed and the problem could have been prevented. The licensee is reviewing procedures with all personnel.

| Event Text AGREEMENT STATE REPORT - STUCK SHUTTER
"On May 19, 2010 at 1620 CDT the agency [State of Texas] received a phone call from the licensee. The licensee stated that shutter on a fixed gauge had stuck at approximately 1700 CDT on May 18, 2010. The gauge houses a 50 milliCurie Cesium (Cs) - 137 source. The licensee stated that shutter failed in the open position, the normal operating position for the gauge, and that exposure rates in the area were normal. The gauge is located high above the ground, on the side of a water tank. The licensee stated that they had contacted the manufacturer and have scheduled a repair of the gauge within the next 30 days. The licensee stated that they were going to continue to use the gauge, as it was in its normal operating state. The agency reminded the licensee that their license specifically states that they are to take the gauge out of operation if it is in need of repair, and should they continue to use the gauge, they would need to request an exemption from the agency. The licensee agreed to request the exemption so that they would not be in violation of their license."
The gauge is a Ronan Gauge S/N 936GG.
