DAMAGED TROXLER GAUGE
The licensee reported that a Troxler Model 3430 nuclear density gauge was damaged at a work site when a road grader backed over the device. The gauge operator was present but was unable to stop the grader. The source was in the shielded position when the accident occurred and appears to be undamaged. A survey shows no contamination or unusual radiation levels. A leak test is in progress and the licensee plans to ship the gauge back to Troxler for repairs.

LOSS OF SPENT FUEL POOL (SFP) COOLING
"At 1500 on 9/18/06, the 'A' SFP pump was declared inoperable due to abnormal noise. The 'B' SFP pump had previously been declared inoperable at 2330 on 9/12/06 [due to a vibration problem]. These events have resulted in a loss of SFP cooling. Current SFP temperature if 89°F. Per the Technical Requirements Manual, SFP temperature is being verified within limits of less than or equal to 150 °F once per 4 hours, and actions have been initiated to restore one SFP cooling system to OPERABLE status prior to the SFP exceeding 120 °F."
The licensee is attempting to repair both SFP pumps in parallel efforts. In addition, a skid mounted SFP cooling system is being prepared for service. The spent fuel pool temperature was at 80 °F when cooling was lost and has increased to 89 °F at the time this report was made. The licensee has calculated that the SFP cooling will have to be out of service for 48 hours to reach the 150 °F limit.
The licensee notified the NRC Resident Inspector.
* * *RETRACTION FROM D. DUTTON TO J. KOZAL ON 11/10/2006 AT 1355 * * *
"The purpose of this notification is to retract the ENS report made on 9/18/2006 at 2223 EDT (Event # 42846). The initial report was conservatively made when both trains of spent fuel pool cooling were lost. Ginna reported the situation as an event or condition that could have prevented the fulfillment of a safety function per 10 CFR 50.72 (b)(3)(v)(D).
"The spent fuel pool cooling system is not credited to mitigate any design basis event, and is not required by the Technical Specifications. The Ginna UFSAR credits the volume of water in the spent fuel pool for providing cooling should forced spent fuel pool cooling be lost."
"Based on this, ENS report (# 42846) is being retracted."
The licensee notified the NRC Resident Inspector.

POTENTIALLY DEFECTIVE PRESSURE TRANSMITTERS SHIPPED TO DIABLO CANYON
"Notification under 10 CFR Part 21 for Model 1154 Series H Pressure Transmitters pursuant to 10 CFR Part 21, section 21.21(a), Rosemount Nuclear Instruments, Inc. (RNII) is writing to inform you that: (a) two Model 1154 Series H pressure transmitters shipped to Pacific Gas & Electric on September 18, 2006, may not conform to RNII's published specification's under accident conditions.
"1.0 Name and address of the Individual providing the information: Mr. Jeffrey W. Schmitt, Vice President & General Manager Rosemount Nuclear Instruments, Inc. 8200 Market Blvd Chanhassen, MN 55317
"2.0 Identification of Items supplied: Two Model 1154 Series H pressure transmitters are affected, as shown below:
Purchase Order - 130124, Sales Order 1732406, Model Number - 1154DH5RC, Serial Number(s) - 0533268, 0533275 Ship date - 18SEP06, Site - Diablo Canyon
"3.0 Identification of firms supplying the item: Rosemount Nuclear Instruments, Inc. 8200 Market Blvd Chanhassen, MN 55317
"4.0 Nature of the failure and potential safety hazard: RNII Model 1154 and Model 1154 Series H transmitters are similar in construction except that the Model 1154 Series H transmitters have a metal shroud, filled with an insulating material, surrounding the sensor module. This feature assures that the Model 1154 Series H transmitter can perform to specifications under certain accident conditions.
"When an order for a pressure transmitter is released to production, a travel card is generated by RNII's business operating system. In the production process a specific list of manufacturing and inspection procedures is joined to the travel card based on the transmitter model number pre-printed on the travel card. These procedures are completed in the order listed to produce the specified pressure transmitter.
"For the two transmitters in question, a list of procedures pertaining to the Model 1154 was attached to the travel card, rather than the procedures for the Model 1154 Series H transmitter. This error was not detected during the production process, and, as a result, the transmitters were assembled and inspected as Model 1154 transmitters.
"5.0 The corrective action which is taken, the name of the individual or organization responsible for that action, and the length of time taken to complete that action: (a) As a precautionary measure, RNII held shipments of all Model 1154 Series H transmitters while production records were reviewed for discrepancies. No additional suspect transmitters were identified. (b) All RNII transmitter travel cards for the prior three years of production were examined for similar discrepancies. No additional suspect transmitters were identified. (c) RNII's field returns history was reviewed for similar nonconformances. None were found. (d) An internal corrective action request was initiated. Corrective actions have been implemented to eliminate the potential for attaching the incorrect list of production procedures. (Completed: Dec 4, 2006)
"6.0 Any advice related to the potential failure of the item: The end user is advised to determine the impact of this defect upon its plant's operation and safety, and take action as deemed necessary. RNII recommends that the affected transmitters be returned to RNII for rework. (Arrangements have been made with PG&E to return the affected transmitters.)"
