As requested, a copy is also being submit ted to the Regional Administrator.. U.S. NRC-Region' III. Fermi 2 has 130 Model 1153 and no Model 1154 Rosemount transmitters. l There are no Model 1153 Series D transmitters and 39 of these 130 Model 1153 transmitters are Series B transmitters manufactured before July 11, 1989. Only 9 of these 39 transmitters normally operate at 'I pressure greater than 500 psi and so are subject to the concern of this supplement. These 9 transmitters will be replaced by' the end of the fourth refueling outage currently scheduled to. begin in March 1994. The other 30 transmitters will remain in service due to their very Icw operating pressures (0-100 psi) and will be checked for-symptoms of oil loss during their surveillance activities. Detroit Edison's. detailed response to NRC items is provided in the Enclosure of this letter. { If you have any questions, please contact Mr. Girija S. Shukla at (313)586-4270.

== Description:== Differential Pressure Transmitter ll. COMPONENT FUNCTION The subject transmitter is used to monitor and alarm differential pressure between the reactor and the main steam piping, which is located between the outboard and third MSIVs. Its output is processed by Foxboro Spec 200 instruments located in the Relay Room Panel H11P9178. The Foxboro Spec 200 powers the transmitters and outputs discrete signals which are used for a permissives for the Main Steam Line Isolation Valve Leakage Control System (MSIVLCS). The MSIVLCS Division 2 uses air from the Division 2 Control Air System. The injection point for the Division 2 system is the main steam drain line upstream of the third MSIVs. The MSIVLCS is not intended to be used during any phase of plant operation other than following a'LOCA. Within 20 minutes after a confirmed LOCA, each Division is armed manually through key operated switches located in the main control room. System activation occurs after several interlocks have been met. Once allintertocks are satisfied, the associated MSIVLCS drain valve will automatically close and remain closed for the duration of the LOCA, Closure of the drain valve prevents venting of the control air and allows it to be directed to the volume between the i isolation valves. During LOCA conditions, after differential pressure has fallen to 5.5 psid, the air injection valve opens automatically. This valve provides air from the control air system to injection points on the main steam drain lines between the outboard and third MSIVs during a l OCA. This results in the pressurization of the piping volume bounded by the closed outboard and third MSIVs. Once this valve is open, it will remain open until differential pressure increases to 8 psid. At this point, the injection valve is closed and will remain closed until the differential i pressure drops again to 5.5 psid. The valve is then reopened and the cycle repeated. This cyclic process takes place throughout the duration of the LOCA accident mitigation period. In addition, the subject transmitter provides a low differential pressure alarm set at 2 psid to alert the plant operator of the possible failure of an outboard MSIV, third MSIV or Drain Valve to be in its fully closed position. If this condition persists for 5 minutes, the system is isolated (shut down). 111. NUREG 0588 SAFETY CATEGORY Differential pressure transmitter B21N487 is classified 2A in accordance ~ith NUREG 0588, Appendix E. It is exposed to the harsh environmental conditions during a LOCA and its operation is essential because it is used for proper MSIVLCS function during a LOCA. The MSIVLCS is not used during HELB conditions nor is this transmitter exposed to a harsh environment during a HELB. IV. COMPONENT OPERABILITY REQ)lDEMENTS The subject differential pressure transmitter must function during a LOCA to provide a permissive and interlock to actuate the MSIVLCS Division 2 injection valve. This valve must operate on and off during a LOCA to maintain a differential pressure between the outboard and the third MSIV and the reactor pressure vessel. This prevents contaminated steam leakage past - the outboard and the third MSIVs into the environment during a LOCA event. Therefore, the operability time requirement for the subject transmitter was determined to be 100 days. i Form NEP-OP1-01 Att 2 P1/1020392 DTC: TDEFA File: 1804 l l l

FAILURE EFFECTS DUE TO SENSOR OIL t.OSS Based on Rosemount's bulletins, the oilloss from the transmitter sensor does not happen catastrophically but happens over a period of time. The time frame for oil loss is proportional to the applied process pressure. When oil loss occurs, a fixnd and/or erroneous transmitter output will result. An enoneous output is an output which may start to track the input as it changes, but then becomes sluggish or offset. Primary Effects. Plant Loaic This transmitter is normally indicates zero, therefore, monthly channel checks cannot be performed. However, the potential for having an undetected oil loss in this transmitter is mitigated by the measures desciibed below. An oilloss could potentia!!y occur from either side of the transmitter. If the effect of advanced oil loss causes a premature achievement of the 5.5 psid setpoint, premature air injection would not occur because the system must be armed manually and the Reactor and Main Steam Line i pressure interiocks must be satisfied. If an oilloss causes a premature achievement of the 2 psid setpoint, the system will provide an alarm and eventually isolate the system. If this occurs, there is a redundant division which will pressureize the inboard MSIVs thus allowing the system to perform its function. If the effect of advanced oilloss causes a stuDgish or no achievement of setpoint, there is a redundant division which will pressurize the inboard MSIVs thus allowing the system to perform its function. Secondary Effects An oilloss failure would have no effect on any other equipment. The Foxboro Spec 200 instruments are designed to operate within the resultant transmitter output range which would occur after a loss of fill oil. VI. INTERIM COMPENSATING MEASURES r This transmitter normally indicates zero. Therefore, reviews for oil loss can only be performed while performing calibrations. Maintenance personnel have been trained to look for symptoms of l l oilloss (sluggish response and offset) while performing calibrations. No symptoms of oilloss have yet been indicated. j Vll. CHANGEOUT This transmitter is scheduled for replacement with a post July 11,1989 manufactured transmitter via WR 000Z923082 no later than the end of RF04. Vll. Summary ' ) Actions have been taken to assure the design function of this transmitter is maintained. This transmitter will reach the 60,000 psi-month maturity by the next refuel outage. Experience has shown that the longer a transmitter is in service without showing symptoms of oil loss, the likelihood of an oilloss failure lessens. Therefore, an oilloss failure of this transmitteris unlikely. if a failure should occur, the function of the system, due to redundancy, will not be lost. l MSIVLCS does not affect any other safety equipment or their functions. i Form NEP-OP1-01 Att 2 P1/1020392 DTC: TDEFA File: 1804

Plant Locic This transmitter is normally saturated off scale high, therefore, monthly channel checks cannot be performed. However, the potential for having an undetected oil loss in this transmitter is mitigated by the measures described below. In this application, an oil loss condition would eventually result in a slow response to an increasing pressure while maintaining a normal response for a decreasing pressure. This condition would have no negative effects on system operation because the setpoint is on decreasing pressure. If the oilloss was severe enough to cause an offset, which would result in an indicated Reactor pressure lower than actual, one of the interlocks in one Division would be prematurely satisfied.

== Description:== Pressure Transmitters 11. COMPONENT FUNCTION These devices monitor HPCI steam supply line pressure. Their output is processed by trip unhs located on the fourth floor of the Auxiliary Building. These trip un!!s power the transmitter and output discrete trip signals on low steam pressure which are utilized to initiate HPCI trip / auto-isolation. Start-up and operation of the HPCI system following a LOCA or HELB is automatica!!y initiated upon detection of either low water level in the reactor vessel or high drywell pressure. These transmitters have no function during normal plant operation. When the HPCI turbine is in operation, the reactor is the source of driving steam. As the reactor pressure decreases, so does the steam pressure at the turbine. When the steam supply pressure decreases to 100 psi, a HPCI trip / auto-isolation signal trips the HPCI turbine and causes closure of several steam line and containment isolation valves to isolate the HPCI turbine. Once activated, the auto-isulation signals are scaled in preventing restart of the HPCI system until the failure condition is corrected and the auto-isolation logic circuits are manually reset. A HPCI trip / auto-isolation alarm is also initiated in the control room. Ill. NUREG-0588 SAFETY CATEGORY The subject transmitters are classified 2A in accordance with NUREG-0588, Appendix E. They are exposed to the harsh environmental conditions of Zones 11 and 12 during a LOCA or a HPCI, RCIC or RWCU HELB. They are essential because they provide permissives for operating HPCI (Emergency Core Cooling) following a LOCA or HELB (except HPCI HELB). They alsc provide a signal for HPCI isolation after HPCI operation is finished. IV. COMPONENT OPERABILITY REQUIREMENTS The HPCI system is required for a maximum of one (1) hour after an accident. The pressure transmitters shall be operable for one (1) hour after a LOCA or HELB as they are required to be operable during the (1) hour post accident period as a permissive to HPCI to keep the HPCI System functional. V. FAILURE EFFECTS DUE TO SENSOR Olt LOSS Based on Rosemount's Bu!!ctins, the oil loss from the transmitter sensor does not happen catastrophically but happens over a period of time. The time frame for oilloss is proportional to the applied process pressure. When oil loss occurs, a fixed and/or erroneous transmitter output. will result. An erroneous output is an output which may start to track the input as it changes, but then becomes sluggish or offset. 1 Form NEP-OP1-01 Att 2 P1/1020392 DTC: TDEFA File: 1804 l

kttacilmentto EFA No. 93-007 NRC-93-0037 R:v 0 Pcg2 3 of 3 EFA CONTINUATION SHEET Primary Effects. Plant Loaic This transmitter is normally saturated off scale high, therefore, monthly channel checks cannot be performed. However, the potential for having an undetected oil loss in this transmitter is mitigated by the measures described be!ow. In this application, an oil loss condition would eventually result in a slow response to an increasing pressure while maintaining a normal response for a decreasing pressure. This condition would have no negative effects on system operation. If the oil loss was severe enough to cause an offset, which would result in an indicated steam supply line pressure lower than actual, a premature trip / auto-isolation of the HPCI system would occur. The Automatic Depressurization System (ADS) is the ECCS opposite division backup to HPCI. If the HPCI system should malfunction, the ADS has the ability to rapidly reduce the pressure in the reactor vessel to a point where the Core Spray system or the Low Pressure injection system can provide the coolant to the reactor. Secondary Effects An oil loss failure would have no effect on any other equipment. The trip units are designed to operate within the resultant transmitter output range which would occur after a loss of fill oil. VI. INTERIM COMPENSATING MEASURES These transmitters are normally saturated off scale high. Therefore, reviews for oilloss can only be performed while performing calibrations. Maintenance personnel have been trained to look for symptoms of oilloss (sluggish response and offset) while performing calibrations and no symptoms of oilloss have yet been indicated. In addition, the calibration data for these transmitters have been trended according to Rosemount Technical Bulletin No. 4. There is no drift indicative of oil loss on any of these transmitters. Vll. Chanoeout These transmitters are scheduled for replacement with a post July 11,1989 manufactured transmitter via WR #000Z920380 and WR #000Z920381 no later than the end of RF04. Vill. Summary Actions have been taken to assure the design function of these transmitters is maintained. In addition, these transmitters will reach the 60,000 psi-month maturity by the next refuel outage. Experience has shown that the lonDer a transmitter is in service without showing symptoms of oil loss, the likelihood of an oil loss failure lessens. Therefore, an oilloss failure of these transmitters is unlikely. If an oilloss failure should occur, the HPCI system would auto-isolate prematurely, but other ECCS systems would still be available for core cooling.
