The following information was provided via e-mail from the State of Ohio Bureau of Radiation Protection:
"At 3:10 PM on Dec 13, 2012 the licensee RSO called the Ohio Department of Health Bureau to report a medical event involving a prostate seed underdose.
"A prostate seed implant procedure performed on 11/27/2012 was found to have failed the prescribed dose-volume criteria via post-implant CT performed on 12/10/2012. The target prescription was 160 Gy to the prostate. The patient was implanted with 88 Iodine-125 seeds with a total activity of 33.44 mCi (0.38 mCi / seed). The post-implant dosimetry was shown to have a D90 of ~40% of the prescription dose with a number of seeds outside of the prostate. The actual implanted activity in the prostate gland was 27.36 mCi. Sixteen seeds were found in the perineum outside the target volume of the prostate + 1 cm as PTV. The dose to this area unintended to receive radiation was about 20Gy to the periphery of the contour volume containing all the 16 seeds.
"The physician was informed of the discrepancy on 12/12/2012 and the patient was informed on 12/13/2012. There is no negative impact expected to the patient, the physician indicates. The patient will be re-implanted to correct for the D90 discrepancy.
"The Bureau of Radiation Protection will be sending an inspector the week of December 17 to investigate the incident."

The following was received from the State of Mississippi via email:
"Licensee's RSO contacted DRH (Division of Radiation Health) by telephone on December 11, 2012 to inform the department that a source retrieval was done earlier that morning on exposure device S/N D2652 source S/N 88902B. This was due to a unsecured exposure device falling to the ground from a valve assembly handle it was place on while performing an exposure. When the radiographer tried to crank the source back into the exposure device he noticed a crimp in the guide tube close to the camera. The radiographer then cranked the source back out to the collimator to provide more shielding and then contacted the RSO for source retrieval. The RSO performed the source retrieval within two hours of being called. The RSO received a dose of 32 mR for the retrieval."

The following information was obtained by ABB, Inc. via fax:
"ABB Coral Springs received notice from ABB Inc. in Florence, South Carolina of a return request by NextEra Energy (Point Beach Nuclear Plant) for one of [their] COM-5 relays. The customer complaint was identified as 'A pin on the telephone relay fell out'.
"ABB Coral Springs received the relay on October 25, 2012 with the telephone relay armature and armature pivot pin disassembled. The assembly process for the telephone relay armature calls for the armature pivot pin to have a knurl at one end and a flare at the opposite end. The knurl and flare secures the armature to the pivot pin. [ABB's] investigation found that on this telephone relay, the pivot pin was flared on the same end as that which had the knurl. It was determined that this was due to an operator error while performing a secondary operation.
"The telephone relay was stamped with a manufacturing date code 08-38, indicating the thirty-eighth week of 2008. It is important to note the date of manufacture, as in mid-2010 the supplier and the assembly manufacturing process of the pin was changed. The hole and flaring was changed such that it is performed prior to cutting the pin to length, eliminating the secondary operation and potential for error.
"In addition to the change to the flaring process described above, corrective action includes the addition of an additional step to [ABB's] final Product Inspection procedure where all telephone relays are verified to have the knurl at one end of the armature pivot pin and a flare at the opposite end.
"Inspection of [ABB's] stock identified no similar condition.
"[ABB has] identified COM-5 and SSC-T relays which shipped that may have a telephone relay of the same vintage as that of the subject telephone relay. There were eleven orders shipped, totaling twenty-five units to three customers; ABB Inc. Florence, S.C., Exelon Business Services and WESCO Distribution, Inc.. ABB has determined that it does not have the capability to perform an evaluation to determine if a defect exists, and therefore in accordance with 10 CFR 21.21(b), [ABB is] notifying [their] affected customers so that they may evaluate the deviation or failure to comply, pursuant to 10 CFR 21(a).
"A failure of the Telephone Relay to operate on either the COM-5 or SSC-T relay can result in the breaker not tripping during an overload condition. This condition could compromise the ability of the relay to perform its intended safety function.
"[ABB is] providing [their] customers with the option of inspecting for evidence of the knurl and flare or returning the relays so [they] may perform the inspection." |

"Recommendation: Immediate Actions:
1.) Review PSS data to determine affected motors.
2.) Establish an Equivalency Evaluation (EE) for Belden EPDM lead wire for EPRI TR 1003481/1001036 utilizing a TVA qualified winding system that included Belden EPDM lead wire (Wyle Test Report 18070-1).
3.) Review Progress Energy and FPL EQ profiles.
4.) Perform a root cause investigation to determine how this issue occurred.
"Evaluation/Action Taken:
1.) Action 1 complete. 13 motors affected and all customers notified.
2.) Action 2 - EE developed and currently being reviewed by affected TVA EQ engineers for approval.
3.) Action 3 - FPL indicated that the FPL motor in question had undergone a recent rewind that replaced the lead. Progress Energy provided the EQ profile on 12/20/12 indicating a significant delta between the Wyle Test Report 18070-1 in Radiation (Normal), Radiation (Accident) and accident temperature (Max). Based on this information, the PSS determination was made that defect in a basic component existed and NRC notification was required in accordance with 10 CFR Part 21, section 21.21(d)(1) and section 21.21(d)(3)(i).

At 1134 CST, the D 4kV Shutdown Board unexpectedly de-energized during performance of post-maintenance testing for the 3D Diesel Generator paralleling circuitry, resulting in loss of power to the 2B RPS subsystem. Primary Containment Isolation System (PCIS) groups 2, 3, 6, and 8 isolations were received along with automatic initiation of A, B, and C Standby Gas Treatment subsystems and A Control Room Emergency Ventilation subsystem due to loss of power to the 2B RPS subsystem. While attempting to reenergize the 2B RPS subsystem, the 2A RPS subsystem was inadvertently de-energized resulting in Unit 2 reactor automatic scram.
"All affected safety systems responded as expected for the loss of RPS and reactor scram. Due to the loss of RPS, the Main Steam Isolation Valves (MSIVs) closed. Reactor pressure did not rise to the automatic initiation set point for Safety Relief Valve (SRV) actuation. Reactor Core Isolation Cooling System (RCIC) and High Pressure Coolant Injection System (HPCI) reactor water level initiation set point of -45" was reached and RCIC and HPCI automatically initiated as designed to restore water level above the initiation set point. Both Recirculation Pumps also tripped on reactor water level of -45". Reactor pressure control was established by manually operating one SRV and water level control established with RCIC. HPCI was returned to standby readiness. The scram was reset, MSIVs were opened, and the Main Condenser was established as a heat sink.
"The scram event from critical is reportable within 4 hours per 10 CFR 50.72(b)(2)(iv)(B). It is also reportable within 8 hours per 10 CFR 50.72(b)(3)(iv)(A) and requires an LER within 60 days per 10 CFR 50.73(a)(2)(iv)(A).
"The NRC Resident Inspector was notified."
The 2A and 2B RPS subsystems were returned to service. The electrical grid is stable and supplying shutdown loads on Unit 2. Unit 1 and Unit 3 were unaffected and continue to operate at 100% power. |

"This is a non-emergency eight hour notification for a loss of Emergency Assessment Capability. This event is reportable in accordance with 10 CFR 50.72(b)(3)(xiii) because the work activity affects the functionality of an emergency response facility.
"Planned maintenance activities are being performed today (December 26, 2012) to the Technical Support Center (TSC) HVAC. The work entails removing power to the system fan and dampers to perform required preventative maintenance (PM) rendering the TSC HVAC non-functional during the performance of this work activity. This work activity is planned to be performed and completed expeditiously within about 16 hours including establishing and removing the clearance and performing post maintenance testing.
"If an emergency condition occurs that requires activation of the TSC, plans are to utilize the TSC concurrent with this work activity as long as habitability conditions allow. Additionally, plans are in place to expedite the return of the system should an emergency condition occur. The Emergency Response Organization duty team members will be relocated to alternate locations if required by habitability conditions in accordance with emergency implementing procedures.
