a. Preserve the integrity of the fuel cladding.

b. Preserve the integrity of the reactor coolant system.

c. Minimize the energy which must be absorbed following a loss-of-coolant accident, and

d. Prevent inadvertent criticality.

This specification provides the limiting conditions for operation necessary to preserve the ability of the system to perform its intended function even during periods when instrument channels may be out of service because of main-tenance. When necessary, one channel may be made inoperable for brief intervals to conduct required surveillance.

The reactor protection system is made up of two independent trip systems.

There are usually four channels to monitor each parameter with two channels in

!( cach trip system. The outputs of the channels in a trip system are combined i in a logic so that either channel will trip that trip system. The tripping of i both trip systems will produce a reactor scram. The system meets the intent , ,,,

i of IEEE-279 for nuclear power plant protection systems. (thy baserfor tWtFp{ns settings of the RPS are discussed in the bases for Specification 2.2.1.

l The measurement of response tinc at the specified frequencies provides assurance that the protective functions associated with each channel are com-l pleted within the time limit assumed in the safety analyses. No credit was $;; g taken for those channels with response times indicated as not applicable. Mg Response time may be demonstrated by any series of sequential, overlapping Q ,

i or total channel test measurement, provided such tests demonstrate the total channel response time as defined. Sensor response time verification may be demonstrated by either (1) inplace, onsite or offsite test measurements, or l (2) utilizing replacement sensors with certified response times.

3 i Except for the MSIVs, the safety analysis does not address individual sensor response times or the response times of the logic systems to which the sensors are connected. For 0.C. operated valves, a 3 second delay is assumed before the valve starts to move. For A.C. operated valves, it is assumed that i the A.C. power supply is lost and is restored by startup of the emergency diesel generators. In this event, a time of 13 seconds is assumed before the i valve starts to move. In addition to the pipe break, the failure of the D.C.

operated valve is assumed; thus the signal delay (sensor response) is concurrent

with the 13-second diesel startup. The safety analysis considers an allowable

{. inventory loss in each case which in turn detemines the valve speed in conjunc-tion with the 13-second delay. It follows that checking the valve speeds and the 13-second time for emergency power establishment will establish the response time for the isolation functions.

The physical phenomenon involved is that the void reactivity feedback due to a pressurization transient can add positive reactivity to the reactor system at a faster rate than the control rods add negative scram reactivity. Each EOC-RPT system trips both recirculation pumps, reducing coolant flow in order to reduce the void collapse in the core during two of the most limiting pressurization events. The two ev'ents for which the EOC-RPT protective feature will function are closure of the turbine stop valves and fast closure of the turbine control valves.

A fast closure sensor from each of two turbine control valves provides input to the EOC-RPT system; a fast closure sensor from each of the other two turbine control valves provides input to the second EOC-RPT system. Similarly, a position switch for each of two turbine stop valves provides input to one E0C-RPT system; a position switch from each or the other two stop valves provides input to the other E0C-RPT system. For each EOC-RPT system, the sensor relay contacts are erranged to form a 2-out-of-2 logic for the fast closure of turbine control valves and a 2-out-of-2 logic for the turbine stop valves. The operation of either logic will actuate the EOC-RPT system and trip both recirculation pumps.

6 sert 10 Each EOC-RPT system may be manually bypassed by use of a keyswitch which l 1s administratively controlled. The manual bypasses and the automatic Operating i Bypass at less than 40% of RATED THERMAL POWER are annunciated in the control room.

The EOC-RPT system response time is the time assumed in the analysis between initiation of valve motion and complete suppression of the electric arc, i.e., 140 ms. Included in this time are: the time from initial valve movement to reaching the trip setpoint, the response time of the sensor, th response time of the system logic, and the time allotted for breaker arc suppression.

SAFETY / RELIEF VALVES (Continued)

Demonstration of the safety-relief valve lif t settings will occur only during shutdown and will be performed in accordance with the provisions of Specification 4.0.5.

The low-low set system ensures that safety / relief valve discharges are t

minimized for a second opening of these valves, following any overpressure tran-sient. This is achieved by automatically lowering the closing setpoint of 6 valves and lowering the opening setpoint of 2 valves following the initial opening. In this way, the frequency and magnitude of the containment blowdown duty cycle is substantially reduced. Sufficient redundancy is provided for the low-low set system such that failure of any one valve to open or close at its reduced setpoint does not violate the design basis.

3/4.4.3 REACTOR COOLANT SYSTEM LEAKAGE 3/4.4.3.1 LEAKAGE DETECTION SYSTEMS The RCS leakage detection systems required by this specification are provided to monitor and detect leakage from the reactor coolant pressure boundary. These detection systems are consistent with the recommendations of Regulatory Guide 1.45, " Reactor Coolant Pressure Boundary Leakage Detection

Systems", May 1973.

3/4.4.3.2 OPERATIONAL LEAKAGE ,

The allowable leakage rates from the reactor coolant system have been based on the predicted and experimentally observed behavior of cracks in pipes. The normally expected background leakage due to equipment design and the detection capability of the instrumentation for determining system leakage was also con-sidered. The evidence obtained from experiments suggests that for leakage ;

somewhat greater than that specified for UNIDENTIFIED LEAKAGE the probability l is small that the imperfection or crack associated with such leakage would grow '

rapidly. However, in all cases, if the leakage rates exceed the values specified or the leakage is located and known to be PRESSURE BOUNDARY LEAKAGE, the reactor '

will be shutdown to allow further investigation and corrective action.

The Surveillance Requirements for RCS pressure isolation valves provide added assurance of valve integrity thereby reducing the probability of gross valve failure and consequent intersystem LOCA. Leakage from the RCS pressure isolation valves is IDENTIFIED LEAKAGE and will be considered as a portion of the allowed limit.

d PY-CEI/NRR-1694 L Attachm2nt 3 Page 1 of 2 SIGNIFICANT HAZARDS CONSIDERATION The standards used to arrive at a determination that a request for amendment involves no significant hazards considerations are included in the Commission's Regulations, 10CFR50.92, which state that the operation of the facility in accordance with the proposed amendment would not (1) involve a 4

significant increase in the probability or consequences of an accident previously evaluated, (2) create the possibility of a new or different kind of accident from any previously evaluated, or (3) involve a significant reduction in a margin of safety.

The determination of no significant hazards submitted with the original request for amendment dated June 24, 1992 remains complete and accurate for that submittal. The following is a description of the determination made for the changes proposed in this letter.

The proposed amendment has been reviewed with respect to these three factors and it has been determined that the proposed changes do not involve a significant hazard because:

1. This proposed change does not involve a significant increase in the probability or consequences of an accident previously evaluated.

The probability of occurrence of a previously evaluated accident is not increased because the instrumentation does not affect the initiation of any accident. The proposed changes do not alter the plant design or methods of operation. The revised wording vill increase the assurance, for the vast majority of instruments and logics, that automatic initiation of the logic will be maintained while instrument surveillance testing or repair is performed.

The consequences of all previously evaluated accidents remains unchanged by this proposed revision. The revised wording assures that the automatic functions remain viable during surveillance testing or repairs, or requires that appropriate compensatory actions be taken. Since the present specifications do not require this check of the logic,'the proposed revision actually has a beneficial result in the consequences of accidents, since the proposed change vill assure automatic instrumentation actuation even while one instrument is being surveilled or repaired.

2. This proposed change does not create the possibility of a new or different kind of accident from any previously evaluated.

The instrumentation involved are those instruments which sense plant problems and/or accidents, and then initiate systems or alarms to respond to the plant problem / accident. The proposed change does not modify any )

of the instruments, or the initiation logic formed by the instruments. I Therefore, no new or different type of an accident has been created. I l

PY-CEI/NRR-1694 L Attachm2nt 3 Page 2 of 2 1

3. This proposed change does not involve a significant reduction in the ,

margin of safety.

As stated above, this proposed change does not result in any plant modification nor change to plant operations. The proposed change vill benefit the availability of the automatic initiation features of the instruments involved during surveillance testing or repairs, by now requiring that a check be made for the vast majority of the instruments to assure that making them inoperable for surveillance testing or repair does not result in a loss of function. This added check assures that a loss of function has not occurred, or if it has, that the Technical Specification ACTION statements be entered promptly. Thus, the margin of safety during surveillance tests and instrument repairs is either increased or is maintained consistent with the June 29, 1992 submittal; and the June 29, 1992 submittal previously justified that there is not a significant reduction in the margin of safety, based on the BVROG analysis results presented in the various Topical teports on Surveillance Interval and Allovable Outage Time Extensions.
