AGREEMENT STATE REPORT - IRIDIUM SOURCE DISCONNECTED FROM RADIOGRAPHY CAMERA

The following information was received from the State of Texas via e-mail:

"On July 6, 2011, the Agency [Texas Department of Health] received a written report from the licensee's Radiation Safety Officer (RSO) that on June 27, 2011, there was a source disconnection at a temporary field site [Dralco, Inc] in Weatherford, Texas. Upon discovering the disconnection, the radiographers roped off the area at the 2 millirem/hour boundary and notified the RSO.

"The RSO arrived on site and confirmed that the source was disconnected. The RSO performed the retrieval by removing the source tube from the camera, shaking the source out of the source tube and placing a lead shield and shot bag(s) over the source with the pigtail exposed. He reconnected the drive cable and the source was cranked back into the camera. The camera was disconnected so that the drive cable and the pigtail connectors could be inspected. No damage was noted and the camera was immediately returned to service.

"The RSO stayed on site approximately one hour to make sure there were no more issues. The RSO stated that the radiographers had failed to connect the pigtail to the drive cable before cranking out the source. The RSO received a dose of 52 mrem. Corrective action includes the event being discussed at the next safety meeting, the radiographers (who were trainers) were instructed to pay attention to safety and the process of connecting the drive cable to the source."

VALVE FAILED LEAK TEST DUE TO A DISC/SHAFT ASSEMBLY MACHINING ISSUE

The following information was received by facsimile:

"After a valve failed a leak test, it was determined that a fixture to machine the valve disc was missing one of the locating pins that maintained the integrity of the shaft bore centerline when machining. It was determined that the pin was missing from the fixture from January 8, 2011, to April 7, 2011 .

"Fisher has conducted a review and determined that the only ASME Section III code and commercial grade dedicated parts machined during this time that would use this fixture were the parts used for the orders referenced [below].

"Fisher Controls has implemented a corrective action program to address this issue.

"Although this notice is dated July 5, 2011 , Palo Verde was officially notified May 13, 2011, when Fisher first became aware of this issue. In the mean time, all affected discs have been returned to Fisher Controls for evaluation.

"Subject: NPS 16 Type A11 Disc/Shaft Assemblies for Palo Verde Orders 500541604 and 500548617 (Fisher Orders 019-F514977 and 019-F515346)."

OFFSITE NOTIFICATION DUE TO A CONTAINED ON-SITE LIQUID RADWASTE LEAK

"This notification is being made under 10 CFR 50.72(b)(2)(xi) of a situation related to the protection of the environment for which a notification to a state agency has been made. On July 8, 2011, South Carolina Electric & Gas Company (SCE&G) made a voluntary notification to the South Carolina Department of Health and Environmental Control (SCDHEC) in accordance with the Nuclear Energy Institute (NEI) Groundwater Protection Initiative for an on-site leak that may exceed 100 gallons. The leak was entirely contained within the V. C. Summer Nuclear Station site boundary.

"On July 7, 2011 during a routine inspection, a leak was discovered in a liquid radwaste line upstream from its final discharge point and downstream of the release radiation monitors. This line contains processed liquid radwaste that has been sampled and permitted for release. The leak occurred inside a containment enclosure which overflowed. The enclosure was drained and the liquid was returned to the plant for disposal. The leak has been isolated and all radwaste release via this pathway has been suspended. The last inspection of this equipment was conducted on February 14, 2011, and revealed no external leakage."

The licensee notified the NRC Resident Inspector.

UNAVAILABILITY OF TSC VENTILATION SYSTEM DUE TO SCHEDULED MAINTENANCE

"At 0400 EDT on Monday, July 11, 2011, the Cook Nuclear Plant (CNP) Technical Support Center (TSC) air conditioning and charcoal filtration systems will be removed from service for scheduled maintenance.

"Under certain accident conditions the TSC may become unavailable due to the inability of the air conditioning and charcoal filtration systems to maintain a habitable atmosphere. Compensatory measures exist to relocate TSC personnel to the unaffected unit's control room if necessary.

"TSC ventilation system maintenance is scheduled to be completed by 2000 EDT on Monday, July 11, 2011.

"The licensee has notified the NRC Resident Inspector.

"This notification is being made in accordance with 10 CFR 50.72 (b)(3)(xiii) due to the loss of an emergency response facility."
