ENCLOSURE I. Bulletin 90-01 requests that power reactor licensees provide/implement the following actions within 120 days of receipt:

A. CONFIRM THAT THE FOLLOWING ACTIONS HAVE BEEN COMPLETED:

1. Identify Model 1153 Series B, 1153 Series D, and Model 1154 pressure or differential pressure transmitters, excluding Model 1153 Series B, 1153 Series D, and Model 1154 transmitters manufactured by Rosemount subsequent to July 11, 1989, that are currently utilized in either safety-related systems* or systems installed in accordance with 10CFR50.62 (the ATWS rule).

RESPONSE

All Rosemount Model 1153 Series B, D and Model 1154 pressure or differential pressure transmitters installed at, Salem and Hope Creek Generating Stations have been identified and documented in a computerized database maintained at each station. There are 266 of these transmitters in service at Hope Creek, 117 at Salem Unit 1, and 120 at Salem Unit 2.

2. Determine whether any transmitters identified in Item 1 are from the manufacturing lots that have been identified by Rosemount as having a high failure fraction due to loss of fill-oil. Addressees are requested not to utilize transmitters from these suspect lots in the reactor protection or engineered safety features actuation systems; therefore, addressees are requested to develop and implement a program to replace, at the earliest appropriate opportunity, transmitters from these suspect lots in use in the reactor protection or engineered safety features actuation systems.

RESPONSE

Prior to the issuance of Bulletin 90-01 there were 63 transmitters installed at Hope Creek, 2 at Salem Unit 2 and none at Salem Unit 1 from the manufacturing lots identified by Rosemount as having a high failure rate due to loss of fill-oil.

One of the Salem 2 transmitters was replaced as scheduled in May 1990. Three of the Hope Creek transmitters were replaced in March 1990 to initiate the replacement program. One other transmitter at Hope Creek was later identified as showing unacceptable symptoms of oil loss and replaced. There remain 59 transmitters from the suspect lots at Hope Creek and one at Salem 2.

NLR-N90149

The breakdown of these transmitters is as follows:

Hope Creek Transmitters in control circuits for RPS, ESF, or ATWS systems:

28 units in "Pressurized Service" - (transmitters which are normally or intermittently operated above atmospheric pressure) 14 units in "Atmospheric Pressure Service" - (transmitters which are operated at or below atmospheric pressure except for a possibility of a brief exposure to 60 psi during a Design Basis Accident)

Transmitters associated with Reactor Protection, ESF or ATWS systems but with indication or alarm only functions:

9 units in "Pressurized Service" J.units in "Atmospheric Pressure Service" Five (5) transmitters are not associated with Reactor Protection, ESF, or ATWS systems A replacement program has been initiated at Hope Creek to replace all 37 transmitters associated with the Reactor, ESF, or ATWS systems in "pressurized service," including those with alarm or indication only function. This replacement program will be completed by the end of the third refueling outage which is scheduled to begin in January of 1991.

There are no plans to replace the 17 units in "Atmospheric Pressure.Service." The manufacturer's investigation of this issue has determined that these units are at no significant risk of suffering from loss of fill-oil. The performance of these units in the enhanced surveillance program has been* exemplary.

The five units not associated with RPS, ESF or ATWS will be monitored through the enhanced surveillance program and scheduled for replacement if inoperability occurs. One of these has been identified as exhibiting symptoms of potential oil loss (Attachment 1) and has been scheduled for replacement during the January 1991 refueling outage.

Salem 2 Transmitter associated with ESF system but with indication or alarm only function

• 1 unit in "Pressurized Service" NLR-N90149

The single transmitter installed at Salem unit 2 has an indication only function. It is currently scheduled for replacement by October 1991.

3. Review plant records (for example, the three most recent calibration records) associated.with the transmitters identified in Item 1 above to determine whether any of these transmitters may have already exhibited symptoms indicative of loss of fill-oil. Appropriate operability acceptance criteria should be developed and applied to transmitters identified as having exhibited symptoms indicative of loss of fill-oil from this plant record review. Transmitters identified as having exhibited symptoms indicative of loss of fill-oil that do not conform to the operability acceptance criteria should be addressed in accordance with

• the applicable technical specification. Transmitters identified as having exhibited symptoms indicative of loss of fill-oil that do not conform to the operability acceptance criteria and are not addressed in the technical specifications should be replaced at the earliest appropriate opportunity. *

RESPONSE

A review of plant records is being conducted to determine whether any of the installed transmitters have exhibited symptoms of oil loss. The result of this review are documented in Engineering Evaluation A-O-VAR-CEE-0296, Rev. 1. All suspect lot transmitter reviews have been completed and of all transmitters identified in_

Item 1, 90% are complete for Hope Creek; 92% are complete for Salem 1 and 89% are complete for Salem 2. The remaining units' reviews will be completed by August 31, 1990. Appropriate operability criteria has been developed and utilized.

Transmitters required to be operable and subsequently declared inoperable will be addressed in accordance with the applicable technical specification action statement. Inoperable non-technical specification transmitters will be addressed by updating the basis for continued operation, if appropriate, and scheduled for replacement.

4. Develop and implement an enhanced surveillance program to monitor transmitters in Item 1 for symptoms of loss of fill-oil. This enhanced surveillance program should consider the following or equally effective actions:

a. Ensuring appropriate licensee personnel are aware of the symptoms that a transmitter, both during operation and during calibration activities, may exhibit if i t is experiencing of loss of fill-oil and the need for prompt identification of transmitters that may exhibit these symptoms; NLR-N90149

b. Enhanced- transmi~ter monitoring to identify sustained transmitter drift;

c. Review of transmitter performance following planned_or unplanned plant transients or tests to identify sluggish transmitter response; -

d. Enhanced awareness of sluggish transmitter response to either increasing or decreasing test pressures during calibration activities;

e. Development and implementation of a program to detect changes in process noise; and

f. Development and application to transmitters identified as having exhibited symptoms indicative of loss of fill-oil of an appropriate operability acceptance criteria. Transmitters identified as having exhibited symptoms indicative of loss of fill-oil that do not conform to the operability acceptance criteria should be addressed in accordance with the applicabie '

technical specification. Transmitters identified as having exhibited symptoms indicative of loss of.

fill-oil that do not conform to the operability acceptance criteria and are not addressed in the technical specifications should be replaced at the earliest appropriate opportunity.

RESPONSE

The enhanced surveillance program at Salem and Hope Creek for Rosemount model 1153 and 1154 transmitters consists of the following:

Drift Analysis - Transmitter drift will continue to be trended in the same manner as.performed for Engineering Evaluation A-O-VAR-CEE-0296, Rev. 1. Station procedures are presently being revised t~ ensure the flow of data to the program coordinator.

Sluggish Response Monitoring - All calibration procedures are being revised to include directions to check for sluggish response during normal calibrations. In addition, transmitters which are identified as potential oil leakers -

may be subjected to a full upper range limit calibration to confirm oil loss.

Process Noise Analysis - A program to record and analyze transmitter response to process noise was developed and -

implemented at Hope Creek as a result of the February 1989 10CFR Part 21 notification issued by Rosemount. This program covers transmitters in processes which provide sufficient noise to generate adequate data and which have not been in service a sufficient time to verify their fully reliable operation. The program is run quarterly as an NLR-N90149

independent monitor of transmitter degradation. It also can be used as a verification method for transmitters which show signs of oil loss by the drift analysis method. A similar program is being initiated at Salem Generating Station. The program will continue for as long as it is judged to be of benefit. *

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 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 engineering safety features actuation systems can be replaced. In addition, while performing the actions requested above, addressees may identify transmitters exhibiting symptoms indicative of loss of fill-oil that do not conform to the established operability acceptance criteria and are not addressed in the technical specifications. As these transmitters are identified, this basis 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 replaced. When developing and updating this basis for continued plant operation, addressees may wish to consider transmitter diversity and redundancy, diverse trip functions (a separate trip function that may also provide a corresponding trip signal), special system and/or component tests, or (if necessary) immediate replacement of certain suspect transmitters.

RESPONSE

The basis for continued operation (JCO) has been completed and documented in Engineering Evaluation (A-O-VAR-CEE-0296, Rev. 1.

This JCO will be updated/revised to include new.transmitter information as necessary.

B. Identify the indicated manufacturer; the model number; the system the transmitter was utilized in; the approximate amount of time at pressure; the corrective actions taken; and the disposition (e.g., returned to vendor for analysis) of Rosemount Model 1153 Series B, Model 1153 Series D, and Model 1154 transmitters that are believed to have exhibited symptoms indicative of loss of fill-oil or have been confirmed to have experienced a loss of fill-oil. This should include Model 1153 Series B, Model 1153 Series D and Model 1154 transmitters manufactured after July 11, 1989.

NLR-N90149

RESPONSE

The list of transmitters at Salem and Hope Creek which have exhibited symptoms of oil loss is included as Attachment _1 ..

c. Identify the system in which the Model 1153 Series B, 1153 Series D, and Model 1154 transmitters from the manufacturing lots that have been identified by Rosemount as having a high failure fraction due to loss of fill-oil are utilized and provide a schedule for replacement of these transmitters which are in use in the reactor protection Qr engineered safety features actuation systems.

RESPONSE

The list of transmitters installed at Hoi:;>e Creek. from the *

• manufacturing *.lots identified by Rosemount. as having high failure rates is included as Attachment 2. Suspect lot trans~itters in

."pressurized service" are scheduled for replacement during the next refueling outages - scheduled to begin in January 1991.

"Atmospheric pressure service" transmitters will continue to be monitored through the enhanced surveillance program, there are no plans to replace these 17 units. The manufacturer's investigation of this issue has determined that these units are at no significant risk of suffering loss of fill-oil. These units do not exhibit any symptoms of pending failure.

Salem Unit 2 has one transmitter from the identified lot, 2PT-919. It monitors safety injection discharge pressure but has no control or trip function. It will be replaced prior to the end of the Fall 1991 refueling outage.

II. Model 1153 Series B, Model 1153 Series D and Model 1154 transmitters that, subsequent to providing the response required by Item 1 above, exhibit symptoms of loss of fill-oil or are confirmed to have experienced a loss of fill-oil should be reviewed for reportability under existing NRC regulations. If determined not to be reportable, addressees are requested to document and maintain, in accordance with existing plant procedures, information

. consistent with that requested in Item I B) above for each transmitter identified.

RESPONSE

Rosemount transmitters that exhibit symptoms of loss of fill-oil or are confirmed to have experienced a loss of fill-oil will continue to be reviewed for reportability. PSE&G intends to maintain the existing data bases for Rosemount transmitters at Artificfal Island.
