(RNII) is writing to inform [the NRC] that one (1) Model 1153 Series B, fourteen (14) Model 1154, and twenty (20) Model 1154 Series H pressure transmitters may not perform their intended safety function."Rosemount Nuclear Instruments, Inc. does not have complete information relating to specific plant applications and therefore cannot determine the potential effects of the condition on plant operation."The thirty-five (35) potentially affected Model 1153 Series B, 1154, and 1154 Series H pressure transmitters were shipped from RNII between April 19, 2011 and August 12, 2011. [The list of Plant Sites that have received the affected transmitters is provided at the end of this report.]"If you have any questions, or require additional information related to this issue, please contact: Mike Dougherty (208) 865 -1112 or Tracy Kaluzniak (952) 949-7159."Identification of items supplied: "One (1) Model 1153 Series B, fourteen (14) Model 1154, and twenty (20) Model 1154 Series H potentially affected units have been shipped.
0910612011 U.S. Nuclear Regulatory Commission Operations Center Event Report Paize 2 Part 21 (PAR) Event# 47246"Identification of firm supplying the item: "Rosemount Nuclear Instruments, Inc. 8200 Market Boulevard Chanhassen, MN 55317"Nature of the failure and potential safety hazard: "On each Model 1153 Series B, 1154, and 1154 Series H transmitter, four diodes are used on a circuit card assembly which is installed within the welded sensor module subassembly.
These diodes convert the AC oscillator signal to a DC current proportional to the pressure applied to the sensor. The diodes (P/N DZ911218A) are manufactured by Microsemi Corporation (MSC)."Recently an unexpected drop in yield was identified during electrical testing of the circuit card assembly.
A hold was placed on production to further investigate the issue. It was determined that the drop in yield was caused by intermittent open diodes on the circuit card assembly.
Failure of one diode will result in an off-scale failure of transmitter output. Failure of two or more diodes may result in an on-scale failure of transmitter output."MSC determined that the intermittent open electrical failures were the result of a poor solder bond formation within the diode at the cathode lead. This was caused by either inadequate heat flow or surface contamination during the component manufacturing process."Working with MSC, RNII used material traceability data to confirm the potential problem was limited to one manufacturer's lot code of the diode. RNII was then able to utilize material traceability data to further identify the specific shipped transmitters affected by this notification."On August 30, 2011, it was concluded that a substantial safety hazard may exist. Rosemount Nuclear Instruments, Inc. does not have sufficient information to determine the safety impact related to the potentially anomalous output in plant applications.
As a result, a notification about the potential substantial safety hazard is being made in accordance with 10 CFR Part 21 to customers who purchased one or more of the thirty-five (35)potentially affected Model 1153 Series B, 1154, or 1154 Series H pressure transmitters."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) RNII held shipments of completed Model 1153 Series B, 1154, and 1154 Series H transmitters and determined which specific units were assembled with diodes from the suspect lot code."(b) RNII quarantined all Model 1153 Series B, 1154, and 1154 Series H transmitters and sub-assemblies in manufacturing while a determination was made as to which specific units were assembled with diodes from the suspect lot code."(c) RNII worked with the diode supplier (MSC) to determine the root cause and identify the suspect lot code. Since this part is no longer being manufactured by MSC, no corrective actions were implemented at MSC."(d) RNII is in the process of reworking all unshipped Model 1153 Series B, 1154, and 1154 Series H transmitters and subassemblies that were completed or in manufacturing that contained diodes from the suspect lot code."(e) Potentially affected pressure transmitters can be returned and reworked at the factory at the end user's request."(f) RNII is qualifying a substitute diode to replace the obsolete DZ911218A diode. The qualification is expected to be complete within the next six months. This qualification will be documented in an update to the Model 1153 Series B, 1154, and 1154 Series H qualification reports"Any advice related to the potential failure of the Item: "RNII recommends that users review the application where any of the thirty-five (35) potentially affected Model 0910612011 U.S. Nuclear Regulatory Commission Operations Center Event Report Page 3 Part 21 (PAR) Event# 47246 1153 Series B, 1154 and 1154 Series H transmitters are used to determine any safety considerations in the operation of the plant.
