SUMMARY
OF PROPOSED CHANGES in accordance with 10 CFR 50.90 Comed is proposing a change to the Technical Specifications (TS) of Facility License Nos. DPR-29 and DPR-30 for the Quad Cities Nuclear Power Station, Units 1 and 2 respectively. The proposed change is to TS Sections 2.2, " Limiting Safety System Settings," and 3/4.1.A, " Reactor Protection System."
The proposed change removes the turbine electro-hydraulic control (EHC) low oil pressure trip from the reactor protection system (RPS) trip function requirements. The Turbine EHC Control Oil Pressure - Low trip function is not required due to the existing Turbine Control Valve Fast Closure trip function, which provides adequate protection during a postulated loss of EHC control oil event. Furthermore, the trip function is not credited in any design basis event described tr. the Updated Final Safety Analysis Repori (UFSAR). This proposed change has been reviewed and endorsed by our nuclear steem supply system (NSSS) supplier, General Eiectric Company.
The proposed changes are described in detailin Section E of this Attachment. The marked up TS pages are shown in Attachment B.
B. DESCRIPTION OF THE CURRENT REQUIREMENTS TS Section 2.2, " Limiting Safety System Settings," establishes the operational settings for protective instrumentation. TS Table 2.2.A-1, Functional Unit 10, provides the following RPS Instrumentation Setraint:
Turbine EHC Control Oil Pressure-Low > 900 psig TS Section 3/4.1.A, " Reactor Protection System," provides the requirements for RPS instrumentation opvability. TS Table 3.1.A-1, Functional Unit 10, establishes the requirements for the Turbine EHC Control Oil Pressure-Low trip function, including applicable OPERATING MODE (s), Minimum OPERABLE CHANNEL (s) per TRIP SYSTEM, and the ACTION (s) necessary if the Limiting Conditions for Operation are not satisfied. TS Table 4.1.A-1 provides the surveillance requiiements for Functional Unit 10.
C. BASES FOR THE CURRENT REQUIREMENT The EHC control system operates using high-pressure oil to provide both control and trip ,
functions for the main turbine. There are several points in this oil system where a loss of 1 oil pressure could result in a rapid operation (i.e. fast closure) of the turbine control valves.
During operating conditions, a fast closure of the turbine control valves causes a reactor ]
pressure transient, which can cause reactor power (i.e. neutron flux) to increase rapidly.

, , (Page 2 of 5)
The loss of EHCTontrol oil event was not originally protected by the turbine control valw fast closure scram function. The control valve fast closure scram function was initially designed as a direct reactor trip on actuation of the fast acting solenoid valves (via a limit switch that sensed actuation). However, loss of the EHC control oil system pressure did not result in actuation of the fast acting solenoid valves. In response to this design concern, Quad Cities Nuclear Power Station added the subject EHC low control oil pressure reactor scram (i.e. Turbine EHC Control Oil Pressure-Low) to ensure safety margins consistant with other pressurization events such as the main generator load reject event. (This modification was installed in the early 1970's.) These RPS switches sense loss of EHC control oil pressure and provide an anticipatory reactor scram signal when EHC fluid pressure is below 900 psig. This trip function anticipates the pressure transient, that would be caused by imminent control valve closure, and results in a reactor shutdown before any significant increase in neutron flux occurs. Note tnat this scram function is bypassed when thermal power is less than 45% of rated thermal output.
D. NEED FOR REVISION OF THE REQUIREMENT in the early 1990s, Comed implemented a design change that replaced the turbine control valve direct scram on fast acting solenoid actuation with a pressure switch, on each control valve, that provides a scram function on low EHC fluid pressure, specifically low l
Fluid Actuator Supply Trip Control (FASTC) pressure at the turbine control valves. This change was accepted by the NRC in Sefety Evaluations dated February 21,1991, and July 23,1991, for Unit 1 and Unit 2, respectively. This modified scram function (i.e.
Turbine Control Valve Fast Closure) is functionally equivalent to the Turbine EHC Control Oil Pressure-Low scram function during a postulated loss of EHC control oil event.
The current TS requirements place an undue burden upon plant operations (i.e., the l testing and maintenance associated with the instrumentation) without a corresponding increase in reactor safety. Removal of this redundant trip function enhances operational safety because the potential for inadvertent p! ant scrams is reduced, the number of test
, cycles on equipment is minimized and the use of plant personnel can be better optimized.

F. SAFETY ANALYSIS OF THE PROPOSED CHANGES The purpose of the EHC system is to provide cooled, filtered, high pressure fluid for the L control of th . turbine valves. The EHC system supplies high-pressure oil to three primary headers:
Fluid Actuator Supply (FAS) Head 3r l
l- Fluid Actuator Supply Trip Control (FASTC), and i l Emergency Trip Supply (ETS)
The FAS header supplies the high pressure oil for positioning selected main turbine steam valves and also provides the oil to the FASTC and ETS headers. The FASTC header is
. used for the control and trip functions of certain turbine steam valves including the turbine control valves. The FASTC fluid enters the control valve positioning unit and is directed to 2 the servo-valve and the fast acting solenoid valve. The FASTC fluid is transmitted l
through the fast acting solenoid valve to the disk dun'p valve. The purpose of the disk dump valve is to seal the end of the hydraulic positioning cylinder so that the servo-valve l
- can direct FASTC fluid into the single acting actuator cylinder of the turbine control valve.
The turbine control valve uses the FASTC pressure to open against a closing spring and steam pressure. The disk dump valve, which normally remains closed by the FASTC pressure, will open to release actuator positioning cylinder pressure, in the event the fast acting solenoid valves are energized.
When the load control unit of the EHC logic system senses a turbine / generator load mismatch, the logic system sends a signal to the fast acting solenoid valve to reposition.
l When the fast acting solenoids reposition, the FASTC fluid begins to drain as a result of l
the repositioned fast acting solenoid valve. The FASTC pressure, which holds the disk dump valve seated, begins to decrease. As a result of the decreasing FASTC pressure, the disk dump valve is forced away from its seat and the FASTC fluid in the hydraulic cylinder is rapidly drained causing the control valve to close rapidly.
In the 1970's, Quad Cities Nuclear Power Station, Units 1 and 2, installed a low EHC fluid actuator (FAS) supply oil pressure reactor scram to anticipate turbine control valve fast :
, closure on a loss of EHC control oil pressure. This trip generates a reactor scram on !
decreasing FAS oil pressure at a setpoint greater than or equal to 900 psig. This modification was installed as recommended by our turbina supplier, General Electric.

! . , (Page 4 of 5)
The original turbine control valve fast closure sensor was designed as a direct trip on actuation of the fast acting solenoid via a limit switch that detected solenoid actuation. In
, response to poor equipment performance, Quad Cities Nuclear Power Station upgraded l l the fast acting solenoid valves in the early 1990s. Based on a recommendation from 1 General Electric, the new design was more reliable and was equipped with a pressuia port for a separate pressure switch. This pressure switch senses decreasing EHC fluid I
(i.e. FASTC) pressure and initiates a scram signal at 2 460 psig (TS Table 2.2.A-1, 4 Functional Unit 11). This scram is anticipatory in nature in that decreasing FASTC I pressure causes the turbine control valves to close in a rapid manner. The low FASTC oil pressure sensor is functionally the same configuration currently installed in most of the General Electric operating BWRs. In addition, most operating BWR plants with EHC control oil systems have only the FASTC oil pressure scram and do not have a low FAS oil pressure scram.
There are no UFSAR design basis events that take credit for the low FAS oil pressure scram. Tile scram resulting from low FASTC oil pressure mitigates all events involving Turbine Control Valve fast closure, including the load rejection with bypass failure event.
The loss of EHC control oil pressure event was also reviewed to determine the consequences of such an event on fuel thermal limits in the absence of the low FAS oil pressure scram. This review determined that the FASTC sensor will initiate a scram in response to a loss of control oil event coincident witn Turbine Control Valve closure. In this respect the low FAS oil pressure scram is a redundant scram since the FASTC scram is capable of the same level of protection. The FASTC scram will provide equivalent protection to fuel thermal limits. This scram configuration with the existing turbine control valve fast closure FASTC oil pressure sensor is functionally the same as the configuration on all BWR 4 inrough BWR 6 designs.
Based on this review, it has been determined that the existing turbine control valve fast closure scram on low FASTC oil pressure provides adequate protection for reactor pressure vessel ASME code compliance with respect to pressure, for an Anticipated Operational Occurrence and for Design Basis Accident criteria. For these reasons, the proposed change which removes the low FAS oil pressure scram is acceptable and does ;
not involve a reduction in plant safety.
Futhermore, the EHC system provides additional protection against a postulated loss of EHC fluid pressure through an independent control hydraulic fluid pressure trip function that initiates a turbine trip when hydraulic fluid pressure decreases to 1100 psig. Above
~ 45% thermal power, a turbine trip results in an anticipatory reactor scram on turbine stop l valve closure.
