ATTACHMENT FLOR1DA POWER AND LIGHT TURKEY POINT UNITS 3 AND 4 NRC BULLETIN 90-01 LOSS OF FILL-OZL IN TRANSMITTERS MANUFACTURED BY ROSEMOUNT Florida. Power and Light provides the following information relative to Turkey Point Units 3 and 4 in response to NRC Bulletin 90-01:

Re ortin Re irement 1.a Provide, within 120 days after receipt of this bulletin, a response that:

a) Confirms that Items 1,2,3,4, and 5 of Requested Actions for Operating Reactors have been completed.

FPL Res onse:

Florida Power and Light confirms that the following actions have been completed:

All Rosemount transmitters models 1153 Series B, and 1153 Series D manufactured prior to July 11, 1989 currently used in either safety-related systems or systems installed in accordance with 10CFR50.62 have been identified. There are no model 1154 .

transmitters installed at Turkey Point Units 3.

and 4. No transmitters were identified as being manufactured by Rosemount but supplied by a different vendor.

~

2 Ten transmitters from manufacturing lots failure fraction due to loss of fill-oilhigh having a have been identified. Six of these ten transmitters are used in the reactor protection or engineered safety features actuation systems. Replacement of the transmitter or its sensor cell for each of the ten transmitters identified will be completed by the end of the dual unit outage currently scheduled to start on November 15, 1990.

3 ~ Plant transmitter calibration records have been reviewed. There are no transmitters which have exhibited symptoms of loss of oil that are currently installed in safety-fill-related systems or systems installed in accordance with 10CFR50.62.

4 ~ An enhanced surveillance program is in place for all Rosemount Model 1153 Series B, and 1153 Series D transmitters currently used in either safety-related systems or systems installed in accordance with 10CFR50.62 manufactured prior to July ll, 1989.

FPL Res onse:

Table 2 of this Attachment provides the requested information.

Re ortin Re irement 2

2. 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-oilshould 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

1) above for each transmitter identified.

FPL Res onse:

Transmitters which exhibit symptoms of loss of fill-oil or are confirmed to have experienced a loss of fill-oil will be reviewed for reportability under existing NRC regulations. If determined not to be reportable, information such as the model number; the system the transmitter was utilized in; the approximate amount of time at pressure; the corrective actions taken; and the disposition of the transmitter will be documented and maintained.
