| Event Text PART 21 REPORT - FOXBORO POWER SUPPLY POTENTIAL FAILURES DUE TO DEFECTIVE TIE WRAPS AND HOLDERS
Mr. John F. Brosemer, President of Integrated Resources, Inc., reported discovery of repeated defects in Foxboro Meter Company's N-2ARPS-A6, Style D power supplies. When manufactured, the power supplies utilized Thomas and Betts TC105A aluminum wire tie holders in random numbers and placements. As the power supplies age, the tie wrap holder adhesive degrades and the tie wraps embrittle resulting in the separation of the tie wraps and loss of holder adhesion to the power supply enclosure. This causes the wraps and holders to fall to the bottom of the enclosure which could result in shorts when the aluminum comes in contact with electronic components. In one particular power supply, all tie wrap holders in use failed and separated from the enclosure.
The power supplies are used in Foxboro SPEC-200 cabinetry that are used throughout the industry. At the time of this notification, Integrated Resources has one power supply from Three Mile Island and two power supplies from Ft. Calhoun undergoing refurbishment. Integrated Resources will be following up this telephonic notification with a written report once their internal investigation is done.
Recommended corrective actions are for affected facilities to open and inspect all power supplies and remove the aluminum tie wrap holders and replace the tie wraps and holders with Teflon types.
* * * UPDATE FROM BROSEMER TO SNYDER AT 1530 EDT ON 4/1/13 * * *
"Suspecting this to be a common mode failure IRI [Integrated Resources, Inc.] opened and inspected two Foxboro N-2ARPS-A6 power supplies which were sent to IRI for refurbishment by Fort Calhoun Nuclear Station. Examination revealed that both of the power supplies have the same failures of the tie wrap aluminum mounting plates adhesive with the majority of the plates being held on the wire bundles by age embrittled nylon wire ties.
"Confirmation of the common mode failure by inspection of the Fort Calhoun Nuclear Stations was on or about 1530 CDT on March 27, 2013.
"IRI is not the OEM or Original supplier for this power supply and cannot provide the number nor locations of these components. However, by searching the RAPID database IRI has found the power supplies at the following:
"Arizona Public Service - Palo Verde Nuclear Generating Station; Constellation Energy - Nine Mile Point Nuclear Power Plant; Detroit Edison - Fermi 2 Nuclear Power Plant; Dominion Nuclear - Millstone Nuclear Power Plant; Dominion Nuclear - Kewaunee Nuclear Power Plant; Eletronnuclear - Angra Nuclear Power Plant; Entergy Nuclear - Arkansas Nuclear One; Entergy Nuclear - Indian Point Energy Center; Entergy Nuclear - Pilgrim Nuclear Power Plant; Entergy Nuclear - J. A. Fitzpatrick Nuclear Power Plant; Exelon Corporation - Three Mile Island Nuclear Plant; Exelon Corporation - Peach Bottom Atomic Power Station; NextEra Energy - Point Beach Nuclear Power Plant; Progress Energy Florida - Crystal River Nuclear Power Plant; Southern California Edison - San Onofre Nuclear Generating Station.
"IRI suspects several other utilities and units are affected by this report.
Corrective action taken: "IRI's preliminary suggestion is inspection and removal of failed tie wrap mounting plates which are being held on to wire bundles by aging nylon tie wraps. IRI also suggests replacement of age embrittled nylon tie wraps with Tefzel tie wraps."

* * * UPDATE FROM JOHN BROSEMER (VIA EMAIL) ON 8/21/13 AT 1628 EDT * * *
"IRI's final recommendations are to remove all Thomas and Betts Co. model TC105A wire tie holders and to replace any embrittled wire ties with TEFZEL wire ties in all of the affected Foxboro Co. power supplies.
"IRI also discovered during the course of the investigation that Thomas and Betts Co. supplied these wire tie holders through normal distribution to all of the manufacturers. IRI recommends that the industry, during normal inspections, inspect for the these types of wire tie holders in all other installed equipment and to remove the failed wire tie holders."

"At 2120 PDT, Diablo Canyon Power Plant experienced a loss of the offsite 230 kV startup power source due to an offsite transmission system relay actuation, resulting in valid anticipatory starts of Units 1 and 2 three emergency diesel generators on each unit. All diesels successfully started but were not loaded. All systems operated as designed with no problems observed.
"The 230 kV startup power source is the only offsite power system designed to be immediately available following an accident. However, the safety related onsite emergency diesel system would have provided power to mitigate the consequences of an accident while the 230 kV was unavailable.
"Restoration of the 230 kV offsite power system is in progress."
The licensee will notify the NRC Resident Inspector.
* * * UPDATE FROM MICHAEL KENNEDY TO HOWIE CROUCH AT 1618 EDT ON 8/21/13 * * *
"230 kV was restored to Operable on 06/24/13 at 0200 PDT. Normal 500 kV Offsite Power remained operable and was unaffected by this event.
"Following further review, Diablo Canyon Power Plant (DCPP) has determined that the loss of the 230 kV system was not a condition that could have prevented fulfillment of the safety function of a system credited to mitigate the consequences of an accident. This power source is not considered to be a safety-related system that is credited to mitigate any accident as described in the DCPP UFSAR, Chapters 6 and 15 accident analyses. PG&E concludes that the emergency diesel generators are the only power source needed to fulfill the accident mitigation function, and they did not become inoperable as a result of this event."
The licensee will be notifying the NRC Resident Inspector. Notified R4DO (Werner). |

"At 1013 hours PDT on August 19, 2013 the Reactor Building Stack Radiation Monitor High Range Detector was declared nonfunctional due to increasing background noise. The Reactor Building Stack Radiation Monitor Intermediate Range Detector remains functional and shows no increase in effluent radioactivity.
"To compensate for the loss of assessment capability due to the nonfunctioning radiation monitoring equipment, an additional Health Physics (HP) Technician trained to acquire offsite dose assessment information on offsite releases will be available. The additional personnel will be pre-staged in support of the Radiation Monitoring System outage and will be mobilized in accordance with guidance in the compensatory measure instructions.
"This event is being reported as a loss of emergency assessment capability in accordance with 10 CFR 50.72(b)(3)(xiii). A follow-up notification will be made when the equipment has been returned to service.
"The licensee will notify the NRC Resident Inspector."

"Initial investigation into the cause of the malfunction of the Reactor Building Stack Radiation Monitor High Range Detector revealed that the condition also affected the Reactor Building Stack Radiation Monitor Intermediate Range Detector. Therefore, this monitor has also been declared non-functional as of 1633 hours PDT on August 19, 2013. Compensatory measures remain in effect to provide emergency response capability for assessing and monitoring actual or potential offsite consequences of a radiological release through this pathway. Corrective actions are being pursued to restore the affected monitors to functional status."

"The cause of the increased background noise for the Reactor Building Stack Radiation Monitor-High Range was due to failing cooling components for the instrumentation, resulting in increased electronic background noise in the instrumentation. There has been no change in the radiation levels at the plant.
