observed. The.-faiures ma fested asa very small amount : ofiliage (.tylcajlyonthe orderof iseveral ;drops/minute "or less)4.from the threaded connection -interface between the flange and vent/drain valve seat..
The threaded connection interface in question is made up of three elements:
the threaded flange (thread type 1/4-18 ANPT), the threaded vent/drain valve seat (thread type 1/4-18 ANPT), and Loctite 571TM which is a commercially available product dedicated by RNII for use in this application as a thread sealant. In normal production, a bead of the sealant is applied to the valve seat threads, which is threaded into the flange Page 1 of 4 04/06/2007 FRI 11:24

When standard rework efforts were not effective in resolving this discrepancy, intensive evaluation and root cause analysis of the threaded connection interface and associated production processes was undertaken to identify and understand the. ~rot &aýtuse e.'df 'the-failures.
The results of this analysis and testing suggestd9-asuble tc hange dinthe Lo'tite'57,1 TM.formulation that, vwhile not directly representing -a noh-nconformsriace ':tO the manufacturei-?s publishted specifications, resuIlted in degraded -sealing capability in this threaded connection interface at pressures above 2000 psi (13.78 MPa).
The affected population was bounded by review of empirical manufacturing and transmitter audit test data, which showed that the last known Model 1152 transmitters to pass multiple hydrostatic pressure tests and high static pressure tests without any leakage were associated with a specific lot of Loctite 571TM that was in use until May 12, 2006. Therefore, we have identified the affected population as including all Model 1152 pressure transmitters whose flanges were assembled after this date using subsequent lots of thread sealant. While it is not expected that all Model 1152 pressure transmitter types and range codes would typically be exposed to working pressures greater than 2000 psi (13.78 MPa), all Model 1152 transmitter types (GP, AP, DP, HP) and all range codes (3,4,5,6,7,8,9,0) have been conservatively included in the affected population listed in the attached Appendix. Additionally, thread sealant from subsequent lots, shipped as spare parts kits, are also included in the Appendix (if shipped to your facility) since its sealing capability at this threaded connection interface can not be reasonably assured.
Internalk testing found :no;. leaks 'at test pressures at. or below 2000 psi (13.78 MPa).
Therefore, no leakage is expected from the threaded connection interface for Model 1152 pressure transmitters installed on applications with process pressures of 2000 (13.78 MPa) or less.
Since RNII is not aware of the actual application details or operational history of each Model 1152 transmitter shipped to your facility (process pressures, static pressures, field rework, etc.), for conservatism all Model 1152 pressure transmitters shipped to your facility in the time interval indicated in the first paragraph of this letter are included in the Appendix.

Froffi:EPM ROSEMOUNT NUCLEAR 952 949 5201 04/06//2007 09:26 4029 P.004/021 The table below indicates the maximum working pressure and hydrostatic test pressure specified for Model 1152 pressure transmitters by pressure measuring type and range code. Additionally, the attached Appendix indicating the potentially affected Mode) 1152 pressure transmitters shipped to your facility includes columns for each unit indicating whether the maximum working pressure and/or the hydrostatic test pressure exceeds 2000 psi (13.78 MPa) as we believe they present the greatest potential to exhibit leakage.
5.0 Th*-e>corrective,action -Which !,has been taken; the name of the individual or organization responsible for that action; and the length of time taken to complete that action:
(a)
An internal corrective action request was initiated.
RNII placed a hold on all Model 1152 transmitter shipments while root cause was under investigation.
(Complete: 3/11/2007)
(b)
RNII performed extensive analysis of multiple test samples and finished goods in an attempt to ascertain the root cause of the leakage and reasonably concluded the failures observed were due to the subtle changes in the Loctite 571 Tm thread sealant. As a result, RNII has very conservatively elected to discontinue providing the threaded vent/drain valve seat as an installed/assembled flange option. Additionally, RNII has discontinued its use of Loctite 571TM and will no longer offer it as a spare part. (Complete: 3/11/2007)
(c)
A welded flange vent/drain valve connection interface identical to that used on Model 1153 Series B and Model 1154 pressure transmitters will be the standard configuration going forward on Model 1152 pressure transmitters. The Model 1152 Qualification Report (Report 117415) was updated to Revision G to include ROSEMOUNT" Nuclear Page 3 of 4 04/06/2007 FRI 11:24

Frori:EPM ROSEMOUNT NUCLEAR 952 949 5201 04/06/2007 09:26 #029 P.005/021 justification for the configuration change.
Copies of the revised Model 1152 Qualification Report are available upon request. (Complete: 3/9/2007)
(d)
Per individual customer agreement via an Advance Deviation Request (ADR) or approval of Model 1152 Qualification Report 117415 Revision G, potentially affected transmitters not yet shipped were or are being reworked either by using a welded flange vent/drain valve connection (see (c) above), or by providing the threaded flange on the Model 1152 transmitter as before, but with the vent/drain valve supplied in the transmitter box un-installed. (Ongoing)
(e)
RNII will supply welded vent/drain valve flange at no charge to customers that request them for field rework. The flange part number for ordering is 01153-0175-0002 (per the applicable section of the Model 1152 Operating Manual, note that process o-rings will also require replacement in the course of field rework, and will also be supplied free of charge if requested). Alternatively, RNII will rework returned transmitters using the welded flange configuration at no charge.
See further guidance in section 6.0 below.
6.0 Any advice related to the potential failure of the Item:
The end user is advised to determine the impact of this potential non-conformance on its plant operations and safety and take action as deemed necessary. The vent/drain valve
,seat can be removed and re-installed with a plant approved sealant, a welded vent/drain valve flange(s) can be shipped to the customer for replacement in the field, or the transmitter can be returned to RNII for rework with a welded vent/drain valve flange. If it is determined that return of a pressure transmitter is required, RNII should be contacted to facilitate the return process.
