Subject:
Grand Gulf Nuclear Station Docket No. 50-416 License No. NPF-29 Confirmation of Completed Actions Requested by NRC Bulletin 90-01, Supplement 1
" Loss of Fill-Oil in Transmitter Manufactured by Rosemount GNRO-93/00162 Gentlemen:
By letter dated December 22, 1992, the NRC issued.
Supplement 1 to Bulletin (NRCB) 90-01 " Loss of. Fill-Oil in Transmitters Manufactured by Rosemount".
Supplement 1 to NRCB 90-01 was issued to evaluate licensees compliance with regulations requiring that Rosemount Model 1153 (Series B ar.0 D) and Model 1154 transmitters manufactured prior to July 11, 1989 achieve the desired degree of high functional reliability.
The specific safety concern is that a gradual loss of fill-oil from the transmitter's j
sealed sensing module has the potential to induce transmitter failure and remain undetected while the j
transmitter is in service, resulting in a common mode i
failure.
NRCB 90-01 Supplement i requested licensees to i
take certain actions to resolve this issue and provide j
written confirmation, notifying the staff when these actions were completed.
The GGNS response to NRCB 90-01 Supplement 1 was transmitted by letter dated March 5, 1993.
In this response, we committed to 1) tag non-installed suspect lot i
Rosemount transmitters (i.e.,
transmitters manufactured prior to July 11, 1989). to prevent inadvertent use in their current configuration, 2) to changt the monitoring frequency of transmitters that were projected to " mature" during 1993, and 3) to replace certain " suspect lot" A

" Confirmation of Completed Actions" NRCB Item 2 (c) :
When completed, provide the Staff a written statement confirming completion of Requested Actions Items 1 and 2 to NRCB 90-01 Supplement 1.
GGNS Response:
This transmittal satisfies the request to provide written confirmation upon completion of Items 1 and 2 from the Requested Actions of NRCB 90-01 Supplement 1.
A point by point comparison between a summarized extract from Requested Actions Items 1 and 2 of NRCB 90-01 Supplement 1 and the corresponding GGNS response is provided below.
We plan no further action regarding this issue.
Reauested Actions (Item 1)
Licensees are requested to_ review plant records and identify Rosemount Model 1153 Series B, Model 1153 Series D, and Model 1154 transmitters manufactured prior to July 11,-
1989, that are used or may be used in the future in either safety-related systems or systems installed in accordance with 10CFR50.62 (the ATWS rule), and perform the following requested actions:
Regpested Actions Item 1(a)
Expeditiously replace, or monitor for the
[
life of the transmitter on a monthly basis t
using an enhanced surveillance monitoring program, any transmitters that have a normal operating pressure greater than 1500 psi and that are installed in the reactor protection trip system, ESF actuation systems or ATWS systems...
GGNS Response to Itag,1(a) j GGNS has no transmitters installed that are enveloped by this criteria. As committed in our initial response to NRCB 90-01 Supplement 1,
non-installed Rosemount transmitters 1
manufactured prior to July 13, 1989 have b'een tagged to prevent inadvertent installation in their current configaration. Model 1154-transmitters manufactured by Rosemount are not used in any plant applications. This agIj_on has been comoleted.

Continued Replace, or monitor for the life of the transmitter on a. quarterly basis using an enhanced surveillance monitoring program, any transmitters that have a normal operating pressure greater than 1500. psi and that are used in safety-related applications but are not installed in reactor protection trip systems, ESF actuation systems or ATWS systems...
GGNS Response to Item 1(b)
GGNS.has no transmitters installed that are enveloped by this criteria. As committed in our initial response to NRCB.90-01 Supplernnt 1, non-installed Rosemount transmitters nanufactured prior to July 11, 1989 have been tagged to prevent. inadvertent installation in-their current configuration. Model 1154 transmitters manufactured by Rosemount are not used in any. plant applications. This action has been comnleted.
Requested Actions Item 1(c)
Replace or monitor on a monthly basis using an enhanced surveillance monitoring program, until the transmitter reaches the appropriate psi-month threshold criterion recommended by Rosemount, any transmitters that have a normal operating pressure greater than 500 psi and less than or equal to 1500 psi, that are installed in reactor protection trip systems, ESF actuation systems, or ATWS j
systems. On a case-by-case basis except for j
transmitters that initiate reactor protection i
or ATWS trips for high pressure or low water level, licensees may monitor using an
)
enhanced surveillance monitoring program at least once every refueling' cycle, but not.
exceeding 24' months, if sufficient justification is provided based upon transmitter performance in service and its specific safety function.

GGNS Response to Item 1(c)
In the GGNS response to NRCB 90-01 Supplement 3
1, we reported 10 installed transmitters as i
being enveloped by this criteria.
The 5 transmitters listed in Table 1 of our response were reported to have accumulated 53,450 psi-months against the Rosemount threshold criteria of 130,000 psi-months. As committed in our response, these transmitters have been replaced with transmitters manufactured after July.11, 1989. This astion has been comoleted.
The remaining 5 transmitters were are listed in Tables 2 and 3 of our~ response to Supplement 1 were projected to reach the appropriate psi-month criteria recommended by Rosemount during this year (1993). These transmitters were to remain in the' current 18 month enhanced-surveillance monitoring program until the appropriate psi-month threshold recommended by Rosemount was achieved or until replacement.
l The information reported for these transmitters in our response to NRCB 90-01 Supplement i reflected psi-month data accumulated as of January 1, 1993-(53,320 psi-months). These transmitters have since accumulated an additional 9.8 psi-months prior to plant shut down for the sixth refueling outage (i.e.,
9.4 months of operation
- 1040 psi). These transmitters i
have now accumulated approximately 63,120
)
psi-months, thereby exceeding the psi-month.
threshold of 60,000 psi-months established by Rosemount to warrant continued inclusion in
'i an enhanced surveillance monitoring program.
I As such, these transmitters have been removed from the enhanced surveillance monitoring program.
This action has been completed.

GGNS Resoonse to Item 1(dl As provided in Table 4 of our response to-NRCB 90-01 Supplement 1, GGNS has 4 transmitters that are enveloped by this criteria.
As recommended by the bulletin supplement, these transmitters were included in our enhanced surveillance monitoring program to be monitored on a 18 month frequency until the appropriate psi-month criteria recommended by Rosemount is achieved.
Requested Action 1(e) i At licensee discretion, exclude from the enhanced surveillance monitoring program any transmitters that have a normal operating pressure greater than 500 psi and less than or equal to 1500 psi that have reached the appropriate psi-month threshold recommended by Rosemount (60,000 psi-months or 130,000 psi-months depending on the range code of the transmitter)...

GGNS ResDonse to Item 1(f)
GGNS has 95 transmitters that are enveloped by this criteria. As permitted by NRCB 90-01 Supplement 1, these transmitters have been excluded from the enhanced surveillance monitoring program.
Requested Actions (Item 2)
Licensees are requested to evaluate the enhanced surveillance monitoring program to ensure that-the program provides measurement data with an~ accuracy range consistent with that needed for-comparison with manufacturers drift data criteria for determining degradation caused by a loss of fill-oil.
GGNS Response to Item 2 As stated in our initial response to NRCB 90-01 Supplement 1, the enhanced surveillance monitoring program has been evaluated for measurement data accuracy. The calibration data trending has sufficient.
accuracy to detect drift consistent with manufacturers criteria.
