Dear Mr. Seyfrit:
f / /5 p Ig '.
River Bend Station-Unit 1 & 2 Refer To:
RIV Docket Nos. 50-458/I&E Bulletin 80-16 50-459/I&E Bulletin 80-16 I
This letter is an update of Gulf States Utilities Company's (GSU) recent activities concerning I&E Bulletin 80-16., " Potential Misapplication of Rosecoent, Inc. Models 1151 and 1152 Pressure 1
Transmitters With Either "A" or "D" Output Codes".
Previous letters sent to your office addressing Bulletin 80-16 are summarized l
below. A status report is provided on actions being perfotmed and corrective measures to be taken, if necessary, on the subject pres-ure transmitters.
On September 5, 1980, CSU reported that our Architect Engineer (Stone & Webster) did not employ any Rosemount Model 1151 or 1152 pressure transmitters with "A" or "D" output codes for use in safety 7
telated applications.
In a. letter dated December 2, 1980, CSU identified several questionable instruments compiled by our Nuclear
-Steam Supply System vendor (General Electric-GE). Since our sub-mittal, the following instruments have been removed from the list:
A B
Et2-N052 E31-N083 E21-N051 E31-N084 E22-N056 E31-N085 1,.

Uy,
.Mr. Karl V. Seyfrit October 2, 1981 The instruments in Column A were rcrioved from the list because GE determined that tho "C" output codes would not be exposed to low
-temperatures or reverse flow conditions which would cause ambiguous signals. Column B instruments are used on systems applying negative leaaage control.
River Bend Station (RBS) design uses a positive leakage control system.
Our June 19,1%1, letter described actions to review and
^
correct questionable pressure transmitters once the transmitters have.trrived-at the RBS site.
GSU snticipaten that the last instrument will arrive at RBS in the fourth quarter of 1982. At that time, GE will perform corrective j
actions as necessary.
A final response will be submitted including a description of all corrective actions as a result of our evaluation by March 1, 1983.,
hpproximately 1,000 manh'ur's have been expended to date address-o ing IfE 'Balletin 80-16.
