Following Is the 23 FEBRUARY 2012 notification letter In Its enttrety with the above specific updates incorporated: | |||
Pursuant to 10 CFR Part 21, section 21,21(b), Rosemount Nuclear Instruments, Inc. (RNII) is writing to inform you that certain Model 1154 Series H pressure transmitters may not perform within the published steam pressure/temperature accuracy specification. | |||
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 potentially affected Model 1154 Series H pressure transmitters were shipped from RNII beginning In 1988. Model 1154 pressure transmitters (versus Model 1154 Series H) are not affected by this notification. | |||

All Model 1154 Series H range code 4-8 pressure transmitters shipped since the initial release in 1988 are potentially affected. Model 1154 Series H range code 9 pressure transmitters are not affected, nor are Model 1154 (versus Model 1154 Series H) transmitters. | |||

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 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. | |||
Currently, the Model 1154 Series H steam pressure/temperature specification establishes 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 hours. | |||
420°F (215.6CC), 85 psig for 3 minutes 350¶F (176.6' C), 85 psig for 7 minutes 3200 F (160-C), 86 75 psig for 8 hours 265'F (129.4-C), 85 24 psig for 56 hours The Model 1154 Series H steam pressure/temperature accuracy specification will be revised to envelop the observed steam pressure/temperature qualification test data 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 hours. | |||

* For range codes 4-8. if oreisure at the 4mA point (appolied to either the hibh or low side of the transmitter) Is greater than 50% -of the upper range limit, the accuracy sieclficatLon is +/- 2% of upper range limit 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 16, 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. | |||

Pursuant to 10 CFR Part 21, section 21,21(b), Rosemount Nuclear Instruments, Inc. (RNII) is writing to inform you that certain Model 1154 Series H pressure transmitters may not perform within the published steam pressure/temperature accuracy specification.

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 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.
Currently, the Model 1154 Series H steam pressure/temperature specification establishes 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 />.

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 16, 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.
6.0 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.
(a) 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&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:
