DEFECTS AND NONCOMPLIANCE PART 21 GRP BY EMAIL PART 21 - RELIABILITY DEGRADATION OF RESISTORS IN TRIP UNITS AND READOUT ASSEMBLIES "Certain 710DU Trip Units may not perform their intended safety function as a result of certain wire wound precision resistors experiencing a degradation of reliability.

"!ýRFjq~MountjNuclearo 21 June 2012 U.S. Nuclear Regulatory Commission Washington, DC 20555-0001 Attn: Document Control Desk Re: Notification under 10 CFR Part 21 on certain Rosemount Model 710DU Trip Units and 710DU Readout Assemblies Pursuant to 10 CFR Part 21, section 21.21(b), Rosemount Nuclear Instruments, Inc. (RNII) is writing to inform you that certain 710DU Trip Units may not perform their intended safety function as a result of certain wirewound precision resistors experiencing a degradation of reliability. Additionally, certain 71ODU Readout Assemblies used to calibrate 71ODU Trip Units may experience degraded digital display accuracy during calibration due to a similar cause.
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.
This notification affects certain Model 71ODU Trip Units and certain 71ODU Readout Assemblies shipped from RNII between March 16, 2005 and May 10, 2012.
1.0 Name and address of the individual providing the information:
Mr. Marc D. Bumgarner Vice President & General Manager Rosemount Nuclear Instruments, Inc.
8200 Market Boulevard Chanhassen, MN 55317 2.0 Identification of items supplied:
Certain 71ODU Master and Slave Trip Units, as well as certain 71ODU Readout Assemblies shipped from RNII between March 16, 2005 and May 10, 2012. See the enclosed Appendix A for the list of units shipped by customer and/or plant site.
3.0 Identification of firm supplying the item:
Rosemount Nuclear Instruments, Inc.
8200 Market Boulevard Chanhassen, MN 55317 4.0 Nature of the failure and potential safety hazard:
71ODU Master and Slave Trip Units use wirewound precision resistors in various circuit applications, including the following qualified safety functions: 4 to 20mA loop current sense, RTD resistance input bridge, trip point comparator, voltage regulation, and circuit power-up. Non-qualified circuit functions include gross failure comparator, gross failure Page 1 of 4
output, and analog meter indication. 71ODU Readout Assemblies use wirewound resistors in digital display circuitry used to calibrate 710DU Master and Slave Trip Units.
RNII has recently identified an increased failure rate of wirewound resistors during manufacturing testing, as well as an increase in field returns resulting from wirewound resistor failures. Through third party testing and consultation with the manufacturer of the wirewound resistors, it has been determined that certain manufacturing lots may be more prone to premature failure. Circuit card assemblies using resistors from the suspect manufacturing lots were assembled into 710DU product and shipped from RNII between March 16, 2006 and May 10, 2012. Additionally, five 71ODU Master Trip Units were shipped from RNII between March 16, 2005 and June 14, 2010 following a resistor replacement process that used resistors from the suspect manufacturing lots.
The suspected cause of reduced reliability is the use of aggressive flux with higher chlorine content during the supplier's resistor manufacturing process. In certain cases, the flux can penetrate the resistor end cap and corrode the resistive wire element. The failure mode typically experienced -is an electrically "open" condition. However, additional failures have been identified by RNII where the resistance value may drift outside of the specified tolerance interval.
RNII has evaluated resistor applications in the 71ODU product family for the potential impact of an electrically "open" failure mode as well as for a drift in resistance. These conditions may cause the following situations:
71ODU Master and Slave Trip Units Qualified Safety Function o
Drift in the 71ODU trip point setting.
o Drift in the 71ODU trip reset differential setting.
o Failure of the trip logic to activate. In this case, though a trip condition exists, trip output would not change state.
o Inadvertent activation of the trip logic.
o Failure of the 71 ODU Master or Slave Trip Unit to power up from a de-energized state.
Non-Qualified Function o
Drift in the 71ODU high gross fail setting or low gross fail setting.
o Failure of the high gross fail or low gross fail logic to activate. In this case, though a gross failure condition exists the gross failure output would not be activated.
o Inadvertent gross failure indication.
o Inaccurate or off-scale reading of the 710DU Master Trip Unit analog indicating meter.
ROSEMOUNT' Nuclear Page 2 of 4
71ODU Readout Assembly Degradation of the accuracy of the 710DU Readout Assembly digital display. This condition may result in errors during trip point calibration of the 710DU Master and Slave Trip Unit.
As a result of the above analysis, RNII determined on June 14, 2012 that a substantial safety hazard may exist for 71ODU Master and Slave trip units and 71ODU Readout Assemblies, and is therefore issuing this notification.
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) RNII has scrapped all inventories of the suspect resistor manufacturing lots.
(b) RNII has worked with the resistor manufacturer to verify that a less aggressive flux is in use and appropriate manufacturing process changes have been implemented to prevent reoccurrence of this issue.
(c) RNII has required the resistor manufacturer to conduct additional reliability screening on all future manufacturing lots shipped for use in RNII products.
(d) RNII has increased manufacturing burn in time from 48 to 100 hours0.00116 days <br />0.0278 hours <br />1.653439e-4 weeks <br />3.805e-5 months <br /> for all 71ODU Trip Units and 71ODU Readout Assemblies to provide increased detectability of resistor reliability concerns.
Mr. Marc Bumgamer, VP&GM of Rosemount Nuclear Instruments, Inc. is responsible for any further action related to this issue.
6.0 Any advice related to the potential failure of the Item:
RNII recommends that users review the application where any of the potentially affected Model 71 ODU Trip Units or Readout Assemblies are used to determine any safety considerations in the operation of the plant. RNII can provide the following information to address potentially affected product:
For 710DU Master and Slave Trip Units affected by this notification o As of June 14, 2012, approximately 2.5% of 710DU Master and Slave Trip Units shipped between March 16, 2006 and May 10, 2012 have been returned to RNII due to confirmed wirewound resistor failures.
Master and Slave Trip Units can be returned to RNII at the customer's discretion and suspect wirewound resistors will be replaced with resistors manufactured and screened as outlined in section 5.0.
- Alternatively, RNII will provide a kit of resistors manufactured and screened as outlined in section 5.0 to allow customers to replace the resistors.
ROSEMOUNT' Nuclear Page 3 of 4
For 710DU Readout Assembly units affected by this notification RNII has not confirmed any field failures of 71ODU Readout Assemblies manufactured between March 16, 2006 and May 10, 2012 that were a result of wirewound resistor failures.
Readout assemblies can be returned to RNII at the customer's discretion and suspect wirewound resistors will be replaced with resistors manufactured and screened as outlined in section 5.0.
