PART 21 REPORT - ROSEMOUNT PRESSURE TRANSMITTERS WITH NONZERO BASED CALIBRATIONS The following information was received by facsimile:
"During the course of qualification testing to replace certain diodes identified for obsolescence, RNII [Rosemount Nuclear Instruments, Inc.] has determined that Model 1154 Series H range code 4-8 pressure transmitters with a significantly elevated or suppressed 4 mA point may not meet the published steam pressure/temperature accuracy specification.
"The out of tolerance condition observed during steam pressure/temperature qualification testing is not related to the replacement diode changes. It is an inherent performance characteristic related to large zero elevation or suppression.
"The steam pressure/temperature accuracy specification will be revised to account for nonzero based calibrations with a significantly elevated or suppressed 4 mA point.
"This revised specification supersedes the published steam pressure/temperature accuracy specification for all Model 1154 Series H pressure transmitters affected by this notification.
"RNIl recommends that users review the application where 1154 Series H range code 4-8 pressure transmitters are used to determine if there are safety considerations related to the revised steam pressure/temperature specification."

(RNIl) is writing to inform you that certain Model 1164 Series H pressure transmitters may not perform within the published steam pressure/temperature accuracy specification.
Rosemount Nuclear Instruments, Inc. does not have completa Information relating to specific plant applications and therefore cannot determine the potential effects of the condition on plant operation.
The potentially affected Model 1154 Series H pressure transmitters were shipped from RNII beginning In1988. Model 1154 pressure transmitters (versus Model 1154 Series H) are not affected by this notification.
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:
All Model 1154 Series H range code 4-8 pressure transmitters shipped since the Initial release In 1088 are potentially affeoted. Model 1154 Series H range code 9 pressure transmitters are not affected, nor are Model 1154 (versos Model 1154 Series H) transmitters, More detailed information can be found in the enclosed appendices.
, Appendix A lists 1154 model code combinations
- Appendix B lists N-options Specials with Specific Steam Pressure/Temperature Accuracy Specifications
- Appendix C lists U.S. domestic customers to which Rosemount Nuclear instruments, Inc. has shipped one or more 1154 Series H range code 4-8 pressure transmitters Page 1 of 7
3.0 Identification of Items supplied:
Rosemount Nuclear Instruments, Inc.
8200 Market Boulevard Chanhassen, MN 55317 4.0 Nature of the failure and potential safety hazard:
During the course of qualification testing to replace certain diodes identified for obsolescence, RNII has determined that Model 1154 Series H range code 4-8 pressure transmitters with a significantly elevated or suppressed 4 mA point may not meet the published steam pressure/temperature accuracy specification.
The, out of tolerance condition observed during steam pressureltemperature qualification testing is =_ related to the replacement diode changes. It Is an Inherent performance characteristic related to large zero elevation or suppression.
The steam pressure/temperature accuracy specification will be revised to account for nonzero based calibrations with a significantly elevated or suppressed 4 mA point.
Currently, the Model 1154 Series H steam pressure/temperature specification establi.hes an expected accuracy as follows:
Accuracy within +/- (1.0% of upper range limit + 1.0% of span) for range codes 4-8; +/- (2.0% of upper range limit + 0.5% of span) for range code 9 during and after sequential exposure to steam at the following temperatures and pressures, concurrent with chemical spray for the first 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br />.

Accuracy within +/- (1.0% of upper range limit + 1.0% of span)* for range codes 4-8; +/- (2,0% of upper range limit + 0.5% of span) for range code 9 during and after sequential exposure to steam at the following temperstures and pressures, concurrent with chemical spray for the first 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br />.

- For range codes 4-8. if pressure at the 4mA point (applied to eitber the high or low side of the transmitter) Is greater than 60% of the upper range limit, the accuracy specification is +/- 2% of upper range limit.
ROSEMOUNTU Nuclear Page 2 of 7
This revised specification supersedes the published steam pressure/temperature accuracy specification for all Model 1154 Series H pressure transmitters affected by this notification.
The 1154 Series H range code 9 pressure transmitters have a steam pressure/temperature accuracy specification that already envelopes the observed steam pressure/temperature qualification test data and are not affected by this notification.
Model 1154 Series H pressure transmitters ordered with N-option specials which Include specific steam pressure/temperature accuracy specifications may also be affected. See Appendix B for details.
On February 1B, 2012, it was concluded that a substantial safety hazard may exist.
Rosemount Nuclear Instruments, Inc. does not have sufficient information to determine the potential safety Impact 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 affected 1154 Series H pressure 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) Update Model 1154 Series H Qualification Report D8700096 to include the revised steam pressure/temperature specification for pressure transmitters impacted by this notification as noted in Section 4.0.
(b) Update the Model 1154 Series H Product Data Sheet 00813-0100-4631 and Product Manual 00809-0100-4631 to include the revised steam pressure/temperature specification for pressure transmitters Impacted by this notification as noted in Section 4,0.
(c) Update the N0059 Specification Drawing 01154-2704 to include the revised steam pressure/temperature specification for pressure transmitters impacted by this notification as noted in Appendix B.
Completion: March 2012 Mr. Marc Bumgarner, VP&GIM 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 1154 Series H range code 4-8 pressure transmitters are used to determine if there are safety considerations related to the revised steam pressure/temperature specification, Rosemount Nuclear Instruments, Inc. is committed to the nuclear industry and remains dedicated to the supply of high quality products to our customers, Ifyou have any questions, or require additional Information related to this issue, please contact: Mike Dougherty (208) 865-1112 or Tracy Kaluzniak (952) 949-7159.
