21.21(d)(3)(i) DEFECTS AND NONCOMPLIANCE PART 21 - MODEL 1154HP TRANSMITTERS WITH INTEGRAL 1159 REMOTE DIAPHRAGM SEALS MAY EXHIBIT DEGRADED FUNCTIONAL RELIABILITY "Pursuant to 10 CFR Part 21, section 21.21(b), Rosemount Nuclear Instruments, Inc. (RNII) is writing to inform you that certain Model 1154HP transmitters with integral 1159 Remote Diaphragm Seals may exhibit degraded functional reliability.

"The standard maximum working pressure for Model 1154 transmitters with integral 1159 Remote Diaphragm Seals is 2000 psi.

"Per the unique requirements of Point Beach Nuclear Generating Station, Model 11 54HP5RAGN0080 pressure transmitters with integral 11 59A50AS0 111 Remote Diaphragm Seals were manufactured to operate at a non-standard maximum working pressure of 2750 psi.

"Once installed in the field, two transmitters exhibited unexpected drift in the output signal when operated at line pressures of approximately 2235 psi.

"To date there are no known additional reported functional reliability issues with other Model 11 5x Series transmitters with integral 1159 Remote Diaphragm Seals in a similar configuration.

"RNII 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 seven Model 1154HP transmitters with integral 1159 Remote Diaphragm Seals shipped to Point Beach Nuclear Generating Station since March 2013."

(RNII) is writing to inform you that certain Model 11 54HP transmitters with integral 1159 Remote Diaphragm Seals may exhibit degraded functional reliability.

• The standard maximum working pressure for Model 1154 transmitters with Integral 1159 Remote Diaphragm Seals is 2000 psi.

• Per the unique requirements of Point Beach Nuclear Generating Station, Model I I54HPSRAGN0080 pressure transmitters with integral 11 59A5ASO0111 Remote Diaphragm Seals were manufactured to operate at a non-standard maximum working pressure of 2750 psi.

Rosemount Nuclear Instruments, Inc.

8200 Market Boulevard Chanhassen, MN 55317 4.0 Nature of the failure and potential safety hazard:

Technical Overview:

Failure analysis efforts have demonstrated the output drift is due to a slow loss of fill fluid in one of the 1159 Remote Diaphragm Seal systems. The loss of fill fluid is due to a leak in the system, however failure analysis efforts to date have not determined the leak path.

Testing suggests the leak may be related to non-standard processing associated 1159 applications requiring maximum working pressures in excess of 2000 psi.

Potential Safety Hazard:

A leak in 1159 capillary fill fluid can cause the output to slowly drift over time. Excessive loss of fill fluid, over time, may result in a loss of transmitter functionality.

On April 4, 2014, RNI1 concluded that a substantial safety hazard may exist.

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:

Existing and new orders for Model 1I54HP transmitters with Integral 1159 Remote Diaphragm Seals with a maximum working pressure above 2000 psi will undergo extended production drift testing to verify performance prior to shipment.

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:

RNII recommends implementing appropriate drift monitoring of the seven affected Model 1154HP transmitters with integral 1159 Remote Diaphragm Seals.

RNII 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.
