EXCHANGER RESIN.
SAEEIX SIDblElLABLE SULFATES MAY PROMOTE INTERGRANNULAR ATTACK OF INCONEL AT HOT CONDITIONS AND MAY AGGRAVATE FERROUS METAL CORROSION.
DlSEDSSIDS o CALVERT CLIFFS UNIT 1 EXPERIENCED SULFATE CONCENTRATION FLUCTUATIONS UP TO 18G6 PPE WHILE SHUTDOWN FROM MARCH 2 TO MARCH 29, 1989.
o EPRI GUIDELINES SUGGEST CONCENTRATE 0tl 0F.LESS THAN 100 PPB.
c ON MARCH 29, 1989, CALVERT CLIFFS UNIT I INITIATED SHUTDOWN FROM 60% POWER SHORTLY AFTER STARTINC UP, DUE TO INCREASING SULFATE CONCENTRATION.
o LICENSEE HAS CLEA!!ED PRIMARY BY RECIRCULATING REACTOR COOL THROUGH TWO 10N EXCHANGERS.
o ON APRIL 4, 1989, SULFATE CONCENTRATION WAS DOWN TO 39 PPB.

LENERIC ISSUE f ELET 2] - ROSEMOUNT TRANSMITTERS EBDELEB MALFUNCTION OF ROSEMOUNT MODEL 1153 AND 1154 PRESSURE AND DIFFERENTIAL PRESSURE TRANSMITTERS.
i LADEL LOSS OF SILICONE OlL FROM THE TRANSMITTER'S SENSING CELL.
SAFETY SIGNIFICANCE lhAblLITY OF PRESSURE AND DIFFERENTIAL PRESSURE TRANSMITTERS TO PRGVIDE PROPER SIGNALS TO SAFETY-RELATED SYSTEMS SUCH AS REACTOR PROTECT!0N SYSTEM.
DISLUSSJ0E o MILLSTONE UNIT 3 EXPERIENCED FIVE FAILURES OF ROSEMOUNT MODEL 1153 DIFFERENTIAL PRESSURE TRANSMITTERS IN 1986 AND 1987, o ROSEMOUNT INITIALLY INDICATED THAT FAILURES WERE RANDOM.
c IN 1988, MILLSTONE SUBMITTED 10 CFR PART 21 NOTIFICATION INDICATING THAT CAUSE WAS LOSS OF OlL IN THE SENSOR MODULE OF TRANSMITTERS.
o IN FEERUARY 1989, RCSEMOUNT INFORMED THEIR CUSTOMERS OF PCTENTIAL FAILURES OF MODEL 1153 AND 1154 TRANSMITTERS.
o FAILURE MODE IDENTIFIED AS LOSS OF SILICONE OIL FROM i
TRANSMITTER SENSING MODULE POSSIBLY DUE TO POOR BONDING OF SEALS AROUND Dil CHAMBERS. !
c LOSS OF 0IL RESULTS IN REDUCED PERFORMANCE OF TRANSMITTER:
- CRIFT IN EITHER DIRECTION OF ABOUT 1/4% OR MORE PER MONTH, i
- LACK OF RESPONSE OVER TRANSMITTER'S FULL RANGE,
- INCREASE IN TIME RESPONSE, CONTACT: J. CUILLEN SIGEVENT: NO
