"Braidwood Unit 2 was performing a planned plant shutdown for refueling outage A2R18. In accordance with plant shutdown procedures while in Mode 1 (Power Operations) at approximately 15% power, operators attempted to start the Start Up Feedwater (SFWP) pump and the pump immediately tripped on Phase A Overcurrent. The 2A Motor Driven Feedwater pump (MDFWP) was manually started to maintain Steam Generator Water Level during the shutdown and subsequent plant cooldown. While in Mode 3 (Hot Standby) at [550 Degree-F], the 2A MDFWP was manually secured due to pump inboard journal bearing temperature exceeding its [200 Degree-F] operating limit. At 0105 [CDT] an anticipated automatic Auxiliary Feedwater actuation signal was generated on low Steam Generator level (36.3%) and both the 2A and 2B Auxiliary Feedwater pumps (AFP) auto-started. Also at 0105 [CDT] a Reactor Protection System (RPS) Reactor trip signal was received due to low Steam Generator level (36.3%) with the reactor not critical. Both Auxiliary Feedwater trains operated as designed with the Main Steam Dumps in service and the Main Condenser providing the heat sink.
"All systems operated as designed with the exception of the SFWP and the MDFWP described above.
"The plant is currently stable in Mode 5 with both AFPs secured.
"This report is being made per 10 CFR 50.72(b)(3)(iv)(A) for automatic actuation of the (1) RPS Reactor Trip with the reactor not critical and (6) Auxiliary Feedwater System, 8 hour notification."

"This 60-day telephone notification is being submitted in accordance with 10 CFR 50.73(a)(1) and 10 CFR 50.73(a)(2)(iv)(A) to report an invalid actuation of the Unit 2, Train B Containment Ventilation Isolation (CVI) at Sequoyah Nuclear Plant.
"At 1919 EDT on August 7, 2015, during planned performance of a Unit 2 containment vent, the Train B CVI actuated due to an invalid Hi Rad signal from 2-RM-90-131, Containment Vent Radiation Monitor. In addition to the Train B CVI alarm, unexpected alarms were received for 2-RM-90-106, Lower Containment Radiation Monitor and 2-RM-90-112, Upper Containment Radiation Monitor instrument malfunctions as they isolated for the CVI and 2-RM-90-131 Hi Rad alarm. Prior to the invalid Hi Rad alarm, all radiation monitors were stable at their normal values. All required automatic actuations occurred as designed. Upon investigation, the cause of the invalid Hi Rad alarm was due to an exposed shield wire at the 2-RM-90-131 detector. Preventative maintenance had been performed the week prior to the CVI and it is believed the damage occurred at that time.
"Control Room Operators performed Annunciator Response actions and verified by diverse indications that the subject condition was an invalid Hi Rad signal. There were no indications of degraded reactor coolant system parameters or fuel failure. Applicable Technical Specification (TS) Limiting Condition for Operations (LCOs) were entered and the radiation monitors declared inoperable. No Emergency Response criteria were applicable with the subject radiation monitors inoperable. Radiological surveys performed in the vicinity of 2-RM-90-131 verified no abnormal radiological conditions.
"Radiation Monitor 2-RM-90-131 was removed from service, the shield wire was repaired and returned to service with no issues. Radiation Monitors 2-RM-90-106 and 2-RM-90-112 were tested and returned to service. The applicable TS LCOs were exited. At the time of the event, plant conditions for a Hi Rad alarm did not exist; therefore, the CVI was invalid.
"The NRC Resident Inspector was notified." |

"On 10/5/2015, during the Beaver Valley Power Station Unit No. 2 (BVPS-2) refueling outage, while performing planned ultrasonic examinations (UT) on the 66 reactor vessel head penetrations, it was determined, that two penetrations could not be dispositioned as acceptable per ASME [American Society of Mechanical Engineers] Code Section XI in a Reactor Coolant System pressure boundary. The indications of a degraded condition, on these two penetrations, are not through wall, as no leak path was identified. The examinations are being performed to meet the requirements of 10 CFR 50.55a(g)(6)(ii)(D), and ASME Code Case N-729-1, to find potential flaws/indications well before they grow to a size that could potentially jeopardize the structural integrity of the reactor vessel head pressure boundary. All 66 reactor vessel head penetrations are scheduled to be examined during the current refueling outage.
"The plant is currently shutdown and in Mode 6. The reactor vessel head is not currently installed. Repairs are currently being planned and will be completed prior to startup.
"This is reportable, pursuant to 10 CFR 50.72(b)(3)(ii)(A) since the as found indications did not meet the applicable acceptance criteria referenced in ASME Code Case N-729-1 to remain in-service without repair.

| Event Text PART 21 - ELECTRONIC POSITION CONTROLLER FAILED INTERNAL COMPONENT
The following was excerpted from a fax received from the licensee:
"NLI manufactured the reverse engineered units to replace the existing obsolete electronic position controller NLI Model: NLI-10A-LM-P.
"The failed component within the controller was sized based on the original published ratings of the original components installed. The unit had an internal component that was subjected to a current value that was higher than the rating for the component. The actual applied current value was not originally provided to NLI when the units were being designed. NLI and the affected plant has been in communication regarding the component condition since the first reported failure.
"Three of units that initially failed in the plant have already been returned to NLI for failure analysis and design modifications. These units were modified by installing a larger bridge rectifier and wire wound resistor onto the revision 0 circuit board. The modified versions, quantity of three, S/N: NLI-10A-LM-P-1003- 0, NLI-10A-LM-P-1004-0 and NLI-10A-LM-P-1006-0 have been returned to Calloway under purchase orders 689233 SR and 694253 SR and have been accepted and installed into the plant and are working with no reported issues.
The model number NLI-10A-LM-P, has been redesigned with a larger bridge rectifier of a higher rating and wire wound resistor that will withstand the applied current in the intended application. The parent circuit board has also been revised to revision 1 to accept the larger bridge rectifier without impacting other components on the board.
The remaining unmodified revision 0 units that were originally supplied have not yet been returned to NLI for incorporation of the design modification. NLI recommends that at the plant's earliest convenience, the remaining units be returned to NLI to be retrofitted with the latest design configuration (revision 1 circuit board)."
The affected plant is Callaway. |

"At 1725 [EDT] on Monday, October 5, 2015, while updating the site fire safe shutdown analysis report, Pilgrim Nuclear Power Station (PNPS) identified vulnerabilities in two (2) specific fire areas that required a compensatory fire watch. The compensatory fire watches have already been established.
"The specific concern involves the unlikely scenario that fire forces evacuation of the control room. In addition, it is postulated that motor operated valves cannot be operated from their alternate control location due to spurious operation caused by hot shorts in control wiring. The specific failure mode is described in NRC Information Notice (IN) 92-18.
"Engineering modifications are under development and scheduled for implementation to address this specific IN 92-18 concern.
"Based on the above, the condition is reportable to the NRC as an unanalyzed condition that significantly degrades plant safety. As such the condition is reportable under 50.72(b)(3)(ii)(B), and requires an 8 hour notification.
