AGREEMENT STATE REPORT - RADIOGRAPHY SOURCE DISCONNECTED FROM CAMERA

Radiography was being performed at a manufacturing shop and warehouse. The source became disconnected while in the guide tube. The radiographer unsuccessfully attempted to reconnect the source. The RSO was contacted and was able to reconnect the source and return it to the radiographic camera. The camera has been returned to service.

The radiographers pocket dosimeter read off scale high. His dosimeter was later read and indicated a dose of 950 mR. The RSO pocket dosimeter read 150 mR. The licensee estimated the extremity dose was 2 R for each individual. The state does not consider this an abnormal occurrence.

Camera: SPEC 150 serial number 0876

AGREEMENT STATE REPORT - DAMAGED RADIOGRAPHY CAMERA GUIDE TUBE

The following information was provided via email:

"On April 20, 2011 the Agency was notified that a radiography source had failed to retract to the shielded position because the material being radiographed had fallen on the guide tube and crimped it. Following company procedures, the Radiation Safety Officer was notified and the area was restricted to avoid public or excessive employee exposures.

"Several entries were made to shield the source and allow an authorized individual to straighten the crimped portion of the tube within tolerable radiation fields. After several other trips to place lead shot on the source, four additional trips were required before the crimp in the source tube was straightened and the source was retracted into the shielded position.

"The source retriever and his assistance received nominal radiation exposures during the procedure and no public exposures reportedly occurred. No violations were cited."

Texas Incident #: I-8838.

LOSS OF EMERGENCY SIRENS DUE TO LOSS OF ELECTRIC POWER

"At approximately 1030 EDT on April 27, 2011, [Sequoyah Nuclear Plant] received notification from TVAs Operations Duty Specialist that >30% of offsite sirens are not functional resulting in a 'major loss' of offsite [automatic] public notification [capabilities]. The loss of offsite sirens is due to loss of electrical power caused by severe thunderstorms and high winds in the area. Thirty five sirens are not functioning (32 sirens are considered 30%). Efforts are in place to restore offsite sirens to service.

"At 1044 EDT on April 27, 2011, power was restored to 2 offsite sirens leaving 33 offsite sirens not functional.

"At 1050 EDT on April 27, 2011, TVA's Operations Duty Specialist made a notification to Tennessee Emergency Management Agency (TEMA) and Hamilton County Emergency Response."

The licensee has notified the NRC Resident Inspector.

* * * UPDATE FROM JEFF EPPERSON TO DONG PARK ON 4/29/11 AT 0514 EDT * * *

Sequoyah Nuclear Plant reported that 28 of 108 sirens are not functional (26%) which is below the 'major loss' of offsite automatic public notification capabilities threshold.

The licensee has notified the Tennessee Emergency Management Agency (TEMA) and Hamilton County Emergency Response. The licensee will notify the NRC Resident Inspector.

BOTH OFFSITE POWER SOURCES DECLARED INOPERABLE DUE TO EFFECTS OF INCLEMENT WEATHER

"At 1929 EDT, both off-site A.C. power sources to Sequoyah were declared inoperable due to the effects of inclement weather on the TVA transmission system. This determination was made after a review of grid conditions confirmed that pre-analyzed grid/offsite power requirements could not be met. Both Sequoyah Units have entered TS LCO 3.8.1.1, action d, for two inoperable offsite power sources. It has not been determined when this condition will no longer exist.

"Although inoperable, off-site A.C. sources remain connected to Sequoyah; emergency diesel generators are not running nor required to be at this time."

T.S. LCO 3.8.1.1, action d, requires verifying EDG operability within 8 hours and restoration of both offsite power sources within 24 hours or placing both Units in mode 3.

The licensee informed the NRC Resident Inspector.

* * * UPDATE FROM JEFF EPPERSON TO PETE SNYDER AT 0203 EDT ON 4/28/11 * * *

As of 0119 EDT the licensee has two operable offsite power sources qualified through transmission and reliability analysis. The licensee exited their LCO Condition. The grid condition is now yellow.
