AGREEMENT STATE REPORT - FAILURE OF RADIOGRAPHY SOURCE TO RETRACT

The following information was received via E-mail:

"On January 13, 2012, the Agency [Texas Department of State Health Services, Radiation Branch] was notified by the licensee that a source disconnect had occurred on January 10, 2012 at one of their job sites. The radiographer was using a Spec model 300 radiography camera containing a 116 curies cobalt-60 source. They had completed 20 exposures. After their last exposure, they approached the radiography camera and noted that their dose rate instrument was indicating that the source was not shielded. The radiographer returned to the end of the crank out device to make sure that he had retracted the source. The radiographer found that while the drive cable was completely retracted, the lock was not operating, and the source was still exposed. The radiographer contacted the company's Radiation Safety Officer (RSO). The radiographers set new boundaries at two millirem per hour and waited for the RSO. The RSO arrived at the location and determined that the source was located in the collimator. The RSO retrieved the source without incident.

"An inspection of the connector on the source pig tail indicated that it had spread allowing it to disconnect. The licensee is sending the source to the manufacturer for inspection. No exposure limits were exceeded during this event. Additional information will be provided as it is received in accordance with SA-300."

Texas Incident #: I-8919.

EXCESSIVE LEAKAGE FROM RCP SEAL RETURN

"Plant shutdown from 100% due to increased leakage from 21 RCP [Reactor Coolant Pump] seal return was commenced at 0100 EST. A manual reactor trip was actuated in accordance with plant procedures at 25% power. Auxiliary feedwater pump was placed in service prior to the reactor trip, per plant procedures. Decay heat is being removed via the condenser steam dumps. All offsite power sources are available. All equipment operated as expected."

The licensee has notified the NRC Resident Inspector and other government agencies.

* * * RETRACTION FROM CHARLES ROKES TO HOWIE CROUCH AT 0940 EST ON 2/15/12 * * *

"Subsequent review concluded the condition did not meet reporting criteria. A normal plant shutdown was initiated in accordance with plant procedures for a known problem with the 21 RCP # 1 seal whose seal leakoff rate had reached an administrative alarm limit. Shutdown was not required by the Technical Specifications. On January 10, 2012, at 0100 hours [EST] a plant shutdown commenced per plant operating procedure 2-POP-2.1. At 0436 hours, the reactor was manually tripped in accordance with procedure 2-POP-3.1. This event is not reportable as the reactor trip was part of a normal shutdown for corrective maintenance."

The licensee has notified the NRC Resident Inspector. Notified R1DO (Powell).

OFFSITE NOTIFICATION TO STATE OF FLORIDA DUE TO EXCEEDING WASTEWATER DISCHARGE PERMIT LIMIT

"Florida Department of Environmental Protection was notified at 1130 EST on 01/10/12 that Stormwater Basin Discharge for the month of December exceeded the total monthly allowable limit for Total Suspended Solids (TSS).

"The Monthly Average for TSS limit is 34 mg/l. The limit per the St. Lucie Plant DEP Discharge Permit is 30 mg/l for the month. This limit was exceeded due to rainfall and required pumping prior to an additional sample point.

"While the basin was pumped, the Daily Maximum Limit of 100 ppm was not exceeded.

"The FDEP representative concurred that there was no threat to the public as a result of this discharge.

"This non-emergency notification is being made pursuant to 10 CFR 50.72(b)(2)(xi) due to the Offsite Notification to the Florida Department of Environmental Protection."
