AGREEMENT STATE REPORT - DISCONNECTED RADIOGRAPHY SOURCE

The following report was received via facsimile:

"On November 13, 2008, around 9:25AM at the Louisiana Technical College - T.H. Harris Campus, Nondestructive Testing Department had a misconnection on an Amertest 660B camera with serial number 1641 from the control cable to the source assembly. The camera had a 43.9 Ci source of Ir-192 with serial number 48634B. The students cranked the source out to do the area survey. After completion of the survey, they tried to return the source to it's shielded position. At that time, they could not return it back to the shielded position. The RSO was notified and determined it could possibly be a misconnect. QSA Global was called to retrieve the source. QSA Global retrieved the source and performed further evaluation. The camera and source were returned to QSA Global. QSA Global determined that it could possibly be a defective male connection on the source assembly. All safety procedures were followed. According to the facility, none of the students were in any kind of danger of being overexposed."

RELAY FAILED TO ACTUATE AS A RESULT OF INCORRECT RECYLE SPRING

Florida Power and Light reported to Tyco that during normal operation one nuclear relay failed to actuate. Tyco investigated and determined that a Tyco electronic relay, E7024 style 4 pole off delay, has an incorrect recycle spring installed into the relay. The incorrect recycle spring causes the relay to fail to actuate.

The following was provided by the licensee via fax:

"(i) Name and address of the individual providing the information: Scott Daubert, Quality Assurance Manager, Tyco Electronics - CII of the Global Aerospace Defense and Marine Division, 1396 Charlotte Highway, Fairview, NC USA:28730.

"(ii) Identification of the facility, the activity, or the basic component supplied for such facility or such activity that contains a deviation or failure to comply; Item supplied are E7024 relays with serial numbers beginning with 0808 through 0835. Certificates of Conformance stating exact relay description and serial numbers will be sent to affected customers with notification by December 16, 2008. Tyco sold this safety-related item for specified and unspecified applications. The customers for which Tyco had insufficient information to complete the Part 21 evaluation are listed [below].

"(iii) Identification of the firm constructing the facility or supplying the basic component that contains a deviation or a failure to comply: Tyco Electronics, 1396 Charlotte Highway, Fairview N,C, USA 28730

"(iv") Nature of the defect or safety hazard that could be created by such a deviation or failure to comply: If an incorrect recycle spring is place into the relay, the off-delay timing could be longer than desired.

"(v) The date on which the information of such a deviation or failure to comply was obtained. Tyco Electronics made the determination of the existence of this condition in September 2008. Notice of Limited E7000 Relay Recall will be issued to the customers by 16 December 2008. .

"(vi) In case of a basic component, which contains a deviation or failure to comply, the locations of all such Components in use or being supplied?
Customers that purchased affected safety-related items from Tyco Electronics for unspecified applications are identified [below].

"(vii) The corrective action which has been, is being, or will be taken; the name of the individual or organization responsible for the action; and the length of time that has been or will be taken to complete the action (note, these are actions specifically associated with the identified deviation or failure to comply; The lot of springs in question have been used. No further defects have been found within current stock. A go/no-go gauge has been developed for use in the production line to verify the free length of the recycle spring prior to installation. This will be completed on each spring until we can develop a method to color code the two springs. Customers that purchased affected safety-related items from Tyco Electronics for unspecified applications are identified [below].

"(viii) Any advice related to the deviation or failure to comply about the facility, activity, or basic component that has been, is being given to purchasers or licensees: Based on our evaluation this issue is expected to have a low potential to produce a significant safety concern. However, Tyco Electronics does not have sufficient information to perform an evaluation for unspecified applications. Therefore customers receiving the recall notification should return affected relays for inspection and rework."

Affected plants are as follows: Farley Nuclear, Oyster Creek, Fermi, Waterford, Limerick, Peach Bottom, Turkey Point, Harris, and Brown's Ferry.
