| Unit | SCRAM Code | RX CRIT | Initial PWR | Initial RX Mode | Current PWR | Current RX Mode | | 1 | N | Y | 100 | Power Operation | 100 | Power Operation | Event Text UNANALYZED CONDITION DUE TO DISCOVERY OF DEGRADED FIRE BARRIER WALLS
"During a fire inspection activity involving inspection of fire walls that serve as Appendix R barriers, degradation of some fire walls was identified that was sufficient to prevent these walls from meeting Appendix R requirements as 3-hour fire barriers. In the event of a postulated fire in the affected areas, both safe shutdown paths on the affected unit could be compromised. Given this information, the determination was made that this condition meets the reporting criteria of 10CFR50.72(b)(3)(ii)(B).
"Compensatory measures were already in place in accordance with the plant's Fire Hazard Analysis (FHA) as a result of previous conditions involving degraded penetrations in these same fire areas. The presence of the compensatory measures in addition to automatic fire detection in these fire areas ensure that the safe shutdown paths are preserved until the degraded conditions can be corrected.
"Condition Reports: 850802, 850819"
In addition to automatic fire protection features, the licensee has posted fire watches as a compensatory measure.
The licensee has notified the NRC Resident Inspector.

"As part of the 'extent of condition' corrective action for the condition identified in EN 50351, an inspection activity is in progress to inspect the remaining fire walls for conditions similar to those reported on 8/7/2014. During this inspection, another condition was identified involving some degradation of the fire wall between Fire Area 1023 - RPS MG Set Room and Fire Area 1015 - Annunciator Room. In the event of a postulated fire in the affected areas both safe shutdown paths on Unit 1 could be compromised. Given this information, the determination was made that this condition meets the reporting criteria of 10CFR50.72(b)(3)(ii)(B).
"Compensatory measures were already in place in accordance with the plant's Fire Hazard Analysis (FHA) as a result of previous conditions involving degraded penetrations in these same fire areas and will remain in place until the wall is repaired. The presence of the compensatory measures in addition to automatic fire detection in these fire areas ensure that the safe shutdown paths are preserved until the degraded condition is repaired. The inspection activity is continuing, and this and any subsequent similar condition(s) that meets the reporting requirements will be included in an ENS update report and will be documented in a revised LER at the end of the inspection activity.

"As part of the 'extent of condition' corrective action for the condition identified in EN 50351, an inspection activity is in progress to inspect the remaining fire walls for conditions similar to those reported on 8/7/2014. During this inspection, additional conditions were identified involving multiple fire barriers in the control building that affected both safe shutdown paths on Unit 1 and Unit 2 based on the respective inspection results. In the event of a postulated fire in the affected areas both safe shutdown paths on Unit 1 and 2 could be compromised.
"Given this information the determination was made that this condition meets the reporting criteria of 10CFR50.72(b)(3)(ii)(B).

| Event Text AGREEMENT STATE REPORT - UNABLE TO RETRACT RADIOGRAPHY CAMERA SOURCE
The following information was obtained from the State of Arkansas via email:
"Mistras Group, Inc., ARK-1034-03310, reported the inability to retract a 2.738 TBq (74 Ci) Ir-192 source (Source QSA Global Model A424-9, Serial 10270G) into the radiography exposure device (QSA Global, Model 880 Delta, Serial D9086) on 9/24/2014.
"During the morning of September 24, 2014, the radiographer's written statements indicated that a piece of pipe shifted and rolled onto the guide tube during an exposure. This action caused a crimp in the guide tube and the source was not retractable.
"The radiography crew reset the boundaries to 2.0 mR/hr and contacted the home office. The RSO of the Baton Rouge, Louisiana office responded to the site.
"The RSO reported that upon arrival, the radiography crew had reset the boundaries to 2.0 mR/hr. The source was located in the collimator and the crimp location was 6 inches from the collimator. The RSO placed 50 pounds of lead shot over the collimator and placed a metal plate under the crimp. The RSO then used a hammer to 'round out' the guide tube allowing the source to be retracted into the camera. The guide tube was removed from service and the crank-out was inspected for any damage.
"The RSO stated that he wore an SRD [self-reading dosimeter] with a 0-200 mR range and this was found to be off-scale. The RSO was instructed by the State to submit the dosimetry badge for immediate processing.
"The pocket dosimeters for the radiography crew were reported to read 1 mR and 0 mR respectively.
"No other survey readings, other than the 2 mR/hr boundary, have been reported.
"The State is tracking this event under Arkansas Event Number AR-2014-007 and is continuing to investigate this incident."
* * * UPDATE FROM STEVE MACK TO JOHN SHOEMAKER AT 1245 EST ON 12/04/14 * * *
The following report was received from the State of Arkansas via email:
"The State of Arkansas is providing the following update to event 50500.
"Dosimetry results for the individual performing the source retrieval were received and indicated that a dose of 1.0 millirem had been received. A dose reconstruction performed by the licensee indicated that the highest possible dose received during the source retrieval was 4.538 millirem.
"The State of Arkansas agrees that there was no overexposure as a result of this source retrieval. The licensee provided corrective actions that included review of the licensee's source retrieval procedures and reporting procedures.
"The [State of Arkansas] Department considers this event to be closed."

| Event Text RECEIPT OF A PACKAGE WITH REMOVABLE SURFACE CONTAMINATION
"Per 10 CFR 20.1906(d), [licensee is] reporting receipt of a package of radioactive material with removable surface contamination on the outside of the package greater than NRC reporting limits. The package was received today (November 26, 2014) at around 0800 PST by VA Central California Health Care System. This facility holds permit number 04-01935-03 under the VHA [Veterans Health Administration] master materials license. The package was checked-in and surveyed around 0830 PST. Wipe tests performed on the external surface of the package indicated a removable contamination level of 7155 dpm/cm2 as compared to the regulatory limit of 220 dpm/cm2 for beta-gamma emitters. The package contained seven unit dosages of radiopharmaceuticals ranging between 10 and 40 millicuries each of Technetium-99m and was shipped from Cardinal Health in Fresno, California. The specific radionuclide that resulted in the contamination was not identified but does not appear to be Technetium-99m. The wipe counting statistics were based on Ba-133. The inner packaging materials were not contaminated. The facility immediately notified the vendor/shipper, who serves as the final delivery carrier, about the contaminated package at about 0835 PST. VHA National Health Physics Program was notified around 0845 PST with initial information. As corrective actions, the packaging materials were bagged and set aside in a restricted area at the facility for further evaluation."
