The safety concerns associated with the failures of Rosemount transmitters were identified in NRC Information Notice (IN) 89-42 and four Rosemount Technical Bulletins. As an action item of our Operating Experience Review Program, we identified all Rosemount transmitters, Models 1153 Series B, Series D, and Model 1154, with a manufacturing date prior to July 11, 1989, that were installed in safety-related and ATHS systems at Pilgrim Nuclear Power Station.

In addition, we participated in the BHR Owners Group activities to further investigate failure mechanisms and to develop generic resolutions. He also implemented corrective actions based upon the recommendations included in IN

'89-42, Rosemount Technical Bulletins and BHROG generic resolutions. Upon  ;

receipt of the NRC Bulletin, we reviewed, revised, and completed the previously implemented actions for compliance with the Bulletin requirements.

A list of the Rosemount transmitters described above that are utilized at Pilgrim Nuclear Power Station and details of corrective actions taken to complete Bulletin action items 1, 2, 3, 4 and 5 are provided as an enclosure to this letter. The enclosed list includes transmitters manufactured after July 11, 1989. The corrective actions include replacement of transmitters identified in the suspect lots, development of a basis for continued operation, and implementation of an enhanced surveillance program.

ENCLOSURE 1

BOSTON EDISON COMPANY RESPONSE TO NRC BULLETIN 90-01: I LOSS OF FILL-0!L IN TRANSMITTERS MANUFACTURED BY ROSEMOUNT i Bulletin 90-01 requested Licensees to promptly identify and take appropriate corrective actions for Models 1153 Series B, Series D, and Model 1154 Rosemount i transmitters that may be leaking fill-oil. The Bulletin required specific actions to be completed within 120 days of receipt. He received the Bulletin  ?

on March 19, 1990 and a response under the provision of 10CFR50.54(f) is due by '

July 16, 1990. The Bulletin action items, which are paraphrased, and BECo corrective actions are described below. '

flylletin Action #1 [

Licensees must identify by location all Model 1153 Series B, Series D and Model 1154 Rosemount transmitters that are manufactured before July 11, 1989. This t list must include all safety related applications and ATHS systems.

Resoonse i Boston Edison has compiled the attached "Rosemount Transmitter Performance ,

Tracking List" of Model 1153, Series B transmitters susceptible to the fill-oil leakage problem that are in service at Pilgrim Station in safety-related i applications. There are no Model 1153, Series D or Model 1154 Rosemount transmitters in service at Pilgrim Station. Pilgrim Station's ATHS system currently uses Model 1151 transmitters. Since these transmitters are not susceptible to the fill-oil leakage problem they are not included in this list. l The list has been alphabetically sorted by instrument tag number. Each ,

instrument tag number is accompanied by the service description, model number, serial number, date in service, and relevant information.

This list includes " time at pressure" data (psi-month status) and operability acceptance criteria. The acceptance criteria is viewed as a " flag" for further i assessment of transmitter performance (see response to Bulletin Action #3).

Bulletin Action #2 ,

Licensees are requested to identify all applications where high failure fraction (suspect lot) transmitters are utilized. Recommendations are given to  ;

avoid utilizing these high failure fraction transmitters in the Reactor Protection or Engineered Safety Features Actuation Systems. Licensees are requested to develop and implement a program to replace transmitters installed in these applications at the earliest appropriate opportunity.

Response

The suspect list provided by Rosemount Inc. on December 22, 1989 was used to identify safety cpplications that currently use high failure fraction transmitters. From the suspect list, only 3 transmitters presently remain in service at Pilgrim Station. All other transmitters from suspect lots have been

l .

removed and repaired or will be returned to Rosemount Inc. for repair and upgrading i The 3 transmitters (PT-503A, B and D) monitor main condenser vacuum. These transmitters have been in service for approximately one year and show no signs of the fill-oil leakage problem. Documentation has been developed supporting continued plant operation with these transmitters in service as requested by NRC Bulletin 90-01. He do not plan to replace these transmitters unless perforirance degrades.

Bulletin Action #3 A review of plant records for each transmitter susceptible to the oil leakage ,

issue is requested. This review is intended to identify any of those i transmitters which may._have aircady exhibited symptoms-indicative of' fill-oil i fluid loss. Licensees'are also requested to develop appropriate operability j.

acceptance criteria and initiate corrective actions for each application where  :

transmitters operating performance does not conform to the operability  !

acceptance criteria.

Resoonse 1

{

He have. reviewed plant records for Rosemount transmitters at Pilgrim Station that are susceptible to the fill-oil leakage problem This review identified several_ transmitters-in var,ious stages of oil leakage (as seen by operating trends and the. amount of instrument calibration shift). Each of the transmitters-that exhibited symptoms of oil leakage has since been replaced.

Operability acceptance criteria for each transmitter application has been established utilizing data from Rosemount Technical Bulletin #4 and BHROG guidance. Each transmitter is presently operating within the acceptance criteria and applicable technical specifications. -The operability acceptance i criteria is shown in the attached "Rosemount Transmitter Performance Tracking" i list as' lower and upper drif t limits (expressed in Engineering units). . This 1.ict also provides a historical database fr each transmitter installed for a  !

- specific application. A brief reason for : 9;.' ament is provided.

Bulletin Action #4 Licensees are-requested to implement an enhanced surveillance program for monitoring the operational performance of each transmitter susceptible to the fill-011' leakage problem. This monitoring program should consider the

-following actions or equally effective actions, q

(A) Ensure appropriate personnel are aware-of th6 symptoms that a' transmitter may exhibit during operation or-during calibration if it is ey.periencing a. loss of fill-oil. Personnel must also be encouraged to support the need for early identification and prompt action for any transmitters exhibiting symptoms.

(B) Enhanced transmitter monitoring to identify sustained transmitter s calibration drift.

(C) . Review of transmitter performance following planned or unplanned plant transients to identify sluggish transmitter responses.

-,+

(D)&(E) Develop and' implement a program which monitors process noise to detect possible changes in the operational performance of each applicable transmitter.

(F) Develop appropriate operability acceptance criteria for each transmitter susceptible to the fill-oil leakage issue. Transmitters identified as giving exhibited symptoms indicative of fill-oil loss that=do not conform to the operability acceptance criteria and are not in the technical specifications should be replaced.

Resoonse Pilgrim Station implemented a preliminary enhanced monitoring program upon receipt of Rosemount Technical Builetins and in response to BHROG generic resolutions. The primary intention of this program was to identify symptoms related to the fill-oil leakage problem. Routine monitoring of susceptible transmitters in high pressure applications (i.e. 1250 psi) has occurred under the direction of Pilgrim Station Instruction, SI-SG.1020, " Systems. Engineering Division Trending Guidelines". The monitoring program was revised in accordance with NRC Bulletin 90-01 requirements by adding transmitters in Icw-pressure ~ applications.

There are a total of 73 Model 1153 transmitters in the currently implemented monitoring program. The monitoring program consists of operational data trendings, calibration data trendings, and process noise analysis including sluggish transmitter responses. Also, operability acceptance criteria for each transmitter application has been established (see Response to Bulletin Action

1. 3).

Pilgrim Station has also included in the operations and maintenance training programs, details regarding fill-oil leakage failures and symptoms. Licensed operators.and instrument control technicians have been trained.

The-present' enhanced monitoring program used at Pilgrim Station has been effective in identifying cases of transmitter fill-oil: leakage. A total of 5 transmitters have been identified as showing symptoms using these methods of-monitoring- These 5 transmitters have since been replaced without any new

. observed cases. Each of the 5 defective transmitters will be returned-to Rosemount Inc. for evaluation and repair. This program will continue until resolution is achieved.

Bulletin Ar< tion #5 Document and maintain in accordance with existing plant procedures a basis'for continued plant operation covering the time period from the present until such time that the Model 1153 Series B,1153 Series D, and Model 1154 transmitters a from the manufacturing lots that have been identified by Rosemount as having a high failure fraction due to loss of fill-oil in use in the reactor protection or engineered safety features actuation systems can be replaced. In addition, if. transmitters exhibiting symptoms indicating loss of fill-oil are identified, the. bases for continued plant operation should be updated to address these transmitters covering the time period from the time these transmitters are identified until such time that these transmitters can be replated.

from the suspect list currently. remain in service. He have implemented a basis for continued plant operation covering these. transmitters. Additionally, these-transmitters are being monitored as explained in response to Bulletin Action #4 .

and'to date have not shown symptoms indicative of loss of fill-oil. As'a- '

result ~of our enhanced surveillance program, if additional transmitters.with .

symptoms indicative of loss of fill-oil are identified, appropriate corrective'  !

actions will be implemented. Also, transmitter failures will be reviewed for i reportabil.ity.
