3.2/4.2-31

QUAD CITIES UNITS 1 & 2 DPR-29 & DPR-30 3.2 LIMITING CONDITIONS FOR OPERATION BASES In addition to reactor protection instrumentation which initiates a reactor scram, protective instrumentation has been provided which initiates action to mitigate the consequences of accidants which are beyond the operator's ability to control, or terminace, operator errors before they result in serious consequences. This set of specifications provides the LIMITING CONDITIONS FOR OPERATION for the - primary system isolation function, initiation of the emergency core cooling system, control rod block and standby gas treatment systems.

The-objectives of the specifications are (1) to assure the effectiveness of the protective instrumentation when required by preservint its cEpability to tolerate a single failure of any component of such systems even during periode when portions of such systems are out-of-service for maintenance and (2) to prescribe the trip settings required to assure adequate performance. When necessary, one CHANNEL may be made inoperable for brief intervals to conduct required CHANNEL FUNCTIONAL TESTS and CHANNEL CALIBRATIONS. Some of the settings on the instrumentation that initiate or control coro and containment cooling have tolerances explicitly stated where the high and low values are both critical and may have a substantial effect on safety. It should be noted that the setpoints of other instrumentation, where only the high or low end of the setting has a direct bearing on safety, are chosen at a level away from the normal operating range to prevent inadvartent actuation of the safety system involved and exposure to abnormal situations.

Isolation valves are installed in those lines that panetrate tha primary containment and must be isolated during ss-of-coorant accident so-that the radiation dose livis> . t c- not-exceeded during an accident condition. Actuat eo et 1.hese valves is initiated by the protective instrumen.

  • uon which serves the condition for which isolation is requned (this instrumentation is shown in Table 3.2-1). Such instrumentation must be available for the Applicable OPERATIONAL MODES shown in Table 3.2-1. The objective is to isolate the primary containment so that the guidelines of 10 CFR 100 are not exceeded during an accident.
  • The instrumentation which initiates prir.ary system isolation is connected in a dual bus arrangement. Thus the discussion provided in the bases for Specification 3.1 is applicable here.

The reactor :ow lc. vel instrumentation is set to trip at greater than 8 inches on the level instrument (top of active B 3.2/4.2-1

QUAD CITIES UNITS 1 & 2 DPR-29 & DPR-30 fuel is defined to be 360 inches above vessel zero) and after allowing for the full power pressure drop across the steam dryer the low-level trip is at 504 inches above vessel zero, or 144 inches above the top of active fuel. Retrofit 8x8 fuel has an active fuel length 1.24 inches longer than earlier fuel designs. However, present trip setpoints were used in the LOCA analyses (Lons-of-coolant accident analysis for Dresden Units 2 & 3 and Quad Cities Unita 1 & 2, NEDO-24146A, April, 1979). This trip initiates closure of Group 2 and 3 primary containment isolation valves but does not trip the recirculation pumps (reference SAR Section 7.7.2) . For a trip setting of 504 inches above vessel zero and a 60-second valve closure time, the valves will be closed before perforation of the cladding occurs even for the maximum break. The setting is therefore adequate.

The reactor low-low level instrumentation is set to trip when reactor water level is greater than or equal to 444 inches abovc vescal zero (with top of active fuel defined as 360 inches above vessel zero, -59 inches is 84 inches above the top of active fuel). This trip initiates closure of Group 1 primary containment isolation valves (reference SAR Section 7.7.2.2) and also activates the ECC subsystems, starts the emergency diesel generator, and trips the recirculation pumps.

This trip setting level was chosen to be Icw enough to prevent spurious operation but high enough to initiate ECCS operation nd primary system isolation so that no molting of the fuel

-cladding will occur and so that post accident cooling can be accomplished and the guidelines of 10 CFR 100 will not be exceeded. For the complete circumferential break of a 28-inch recirculation line and with the trip setting given above, ECCS initiation and primary isolation are initiated in time to meet the above criteria. The instrumentation also covers the full spectrum of breaks and meets the above criteria.

The drywell high pressure instrumentation is a backup to the water level instrumentation and, in addition to initiating ECCS, it causes isolation of Group 2 isolation valves. For the breaks discussed above, this instrumentation will initiate ECCS operation at about the same time as the low-low water level instrumentation; thus the results given above are applicable here also. Group 2 isolution valves include the drywell vent, purge and sump isolation valves. Drywell high pressure activates only these valves because drywell high pressure could occur as the result of non safety-related causes such as not purging the drywell air during start up.

Total system isolation is not desirable for these conditions, and only the Group 2 valves are required to close. The low-low water level instrumentation initiates protection for the B 3.2/4.2-2

QUAD CITIES UNITS 1 & 2 DPR-29 & DPR-30 full spectrum of loss-of-coolant accidents and causes a trip of Group 1 primary system isolation valves.

High radiation in the drywell indicates an abnormal situation due to a line break or other abnormal occurrence. To preclude release of potentially highly contaminated material from the drywall, this high radiation isolation automatically closes the Group 2 isolation valves.

Venturi tubes are provided in the main steam lines as a means of measuring steam flow and also limiting the loss of mass inventory from the vessel during a steam line b i :k accident.

In addition to monitoring steam flow, instrumentation is provided which causes a trip of Group 1 isolation valves. The primary function of the instrumentation is to detect a break in the main steam line, thus only Group 1 valves are closed.

For the worst-case accident, main steam line break outside the drywell, this trip setting of 140% of rated steam flow, in conjunction with the flow limiters and main steam line valve closure, limits the mass inventory loss such that fuel is not uncovered, fuel temperatures remain less than 15 0 0*F, and release of radioactivity to the environs is well below 10 CFR 100 guidelines (reference SAR Sections 14.2.3.9 and 14.2.3.10).

Temperature-monitoring instrumentation is provided in the main steam line tunnel to detect leaks in this area. Trips are provided on this instrumentation and when exceeded cause closure of Group 1 isolation valves. Its setting of 200'F is low enough to detect leaks in the order of 5 to 10 gpm; thus it is capable of covering the entire spectrum of breaks. For large breaks, it is a backup to high-steam flow instrumentation discussed above, and for small breaks with the resulting small release of radioactivity, provides isolation bafore the guidelines of 10 CFR 100 are exceeded.

High radiation monitors in the main steam line tunnel have been provided to detect gross fuel failure. This instrumentation causes closure of Group 1 valves, the only valves required to close for this accident. With the established setting of 15 times normal background (without hydrogen addition) and main steam line isolation valve closure, fissi7n product release is limited co that 10 CFR 100 caidelines are not exceeded for this accident (reference SAR Section 14.2.1.7).

Pressure instrumentation is provided which trips when main l steam line pressure drops below 825 psig. A trip of this instrumentation results in closure of Group 1 isolation B 3.2/4.2-3 1

i QUAD CITIES UNITS 1 & 2 DPR-29 & DPR-30 valves. In the REFUEL and STARTUP/ HOT STANDBY OPERATIONAL MODES this trip function is bypassed. This function is provided primarily to provide protection against a pressure regulator malfunction which would cause the control and/or bypass valves to opon. With the trip set at 825 poig, inventory loss is limited so that fuel is not uncovered and peak cladding temperatures are much less than 1500*F; thus, there are no fission products available for release other than those in the reactor water (reference SAR Section 11.2.3).

The RCIC and the HPCI high flow and temperature instrumentation are provided to detect a break in their respective piping. Tripping of this instrumentation results in actuation of the RCIC or of HPCI isolation valves. Tripping logic for this function is the same as that for the main steam line isolation valves, thus all sensors are required to be operable or in a tripped condition to meet single-failure criteria. The trip settings of 170'F and 300% of design flow and valve closure time are such that core uncovery is prevented and fission product release is within limits.

The instrumentation which initiates ECCS action is arranged in a one-out af-two taken twice logic circuit. The single-failure critoria are met by virtue of the fact that redundant core cooling functions are provided, e.g., sprays and automatic blowdown and high pressure coolant injection.

The specification requires that with the number of OPERABLE CHANNELS less than required by the minimum OPERABLE CHANNELS per TRIP SYSTEM requirement, either the CHANNEL (s) is placed in the trip condition or the associated system which it activates is declared inoperable and the ACTION statements of  ;

Specification 3.5 govern. This specification preserves the ef fectiveness of the system with respect to the single-f ailure criteria even during periods when maintenance or testing is being performed.

The control rod block functions are provided to prevent excessive control rod withdrawal so that MCPR does not go below the MCPR fuel cladding integrity SAFETY LIMIT. The trip logic for this function is one-out-of-n; e.g. , any trip on one of the six APRMs, eight IRMs, four SRMs will result in a rod block. The minimum instrument channel requirements assure sufficient instrumentation to assure that the single-failure criteria are met. The minimum instrument channel requirements for the RBM may be reduced by one for a short period of time to allow for maintenance, testing, or calibration. This time period is only 3% of the operating time in a month and does not significantly increase the risk of failing to prevent an inadvertent control rod withdrawal.

B 3.2/4.2-4 I

QUAD CITIES UNITS 1 & 2 DPR-29 & DPR-30 The APRM rod block function is flow-biased and prevents a significant reduction in MCPR, especially during operation at reducod flow. The APRM provides gross core protection, i.e.,

limits the gross withdrawal of control rods in the normal withdrawal sequence.

In the REFUEL and STARTUP/ HOT STANDBY OPERATIONAL MODES, the APRM rod block function is set at 12% of rated power. This control rod block provides the same type of protection in the REFUEL and STARTUP/ HOT STANDBY OPERATIONAL MODES as the APRM flow-biased rod block does in the RUN OPERATIONAL MODE, i.e.,

prevents control rod withdrawal before a scram is reached.

The RBM rod block function provides local protection of the core, i.e., the prevention of TRANSITION BOILING in a local region of the core for a single rod withdrawal error from a LIMITING CONTROL ROD PATTERN. The trip point is flow-biased.

The worst-case single control rod withdrawal error is analyzed for each reload -to assure that, with the specific trip settings, rod withdrawal is blocked before the MCPR reaches the fuel cladding integrity SAFETY LIMIT.

Below 30% power, the worst-case withdrawal of a single control rod without rod block action will not violate the fuel cladding integrity SAFETY LIMIT. Thus - the RBM rod block function is not required below this power level. If a peripheral control rod is selected, the neutron leakage is sufficiently high such that withdrawal of this rod will not violate the fuel cladding integrity SAFETY LIMIT. Thus, the RBM function is not required for withdrawal of peripheral control rods.

The=IRM rod block function provides local as well as gross core protection. The scaling arrangement.is such that the trip setting is less than a factor of 10 above the indicated level. Analysis of the worst-case accident results in rod l

block action before MCPR approaches the MCPR fuel cladding integrity SAFETY LIMIT.

For effective emergency core cooling during small pipe breaks,  ;

the HPCI system must function since reactor pressure does not decrease rapidly enough to allow either core spray or LPCI to operate in time. The automatic pressure relief function is provided.as a backup to the HPCI, in the event the HPCI does l not operate. The arrangement of the tripping contacts is such  ;

as to provide this function when necessary and minimize spurious operation. The trip settings given in the specification are adequate to assure the above criteria are met (reference SAR Section 6.2.6.3). The specification preserves the-effectiveness of the system during periods of maintenance, testing or calibration and also minimizes the risk of inadvertent operation, i.e., only one instrument channel out-of-service.

' Two radiation monitors are provided on the refueling floor which initiate isolation of the reactor building and operation of the standby gas treatment systems. The trip logic is one-out-of-two. Trip settings of less than or equal to 100 Mr/hr for the_ monitors on the refueling -floor are based upon initiating normal ventilation isolation and standby gas 1 treatment system operation so that none of the activity released during the refueling accident leaves the reactor building.via the normal ventilation stack but that all the ,

activity is processed by the standby gas treatment system. l The instrumentation which is provided to monitor the post accident condition' is listed jn Table 3.2-4. The

-instrumentation listed and the LIMITING CONDITIONS FOR OPERATION-on these systems ensure adequate monitoring of the

. containment following a loss-of-coolant accident. Information from this instrumentation will. provide the operator with a detailed knowledge of the conditions resulting from the accident;-based on this information, the operator can make logical decisions regarding post accident recovery.

Allowable outage-times are based on the fact that several diverse instruments are available for guiding the operator shoulG an accident occur, and on the low probability of an instrument being.out-of-service and an accident occurring.

The normal supply of air for the control room ventilation system trains "A" and "B" is outside the service building. In the event of an accident, this source of air may be required B 3.2/4.2-6

l QUAD CITIES UNITS 1 & 2 DPft-29 & DPR-30 to be isolated to prevent high doses of radiation in the control room. Rather than provide this isolation function on a radiation monitor installed in the intake air duct, signals which indicate an accident, i.e., drywell hioh pressure, low water level, main steam line high flow; drywell high radiation, high radiation at the refueling floor monitors, or high radiation in the reactor building ventilation duct, will cause isolation of the intake air to the control room. The above trip signals result in immediate isolation of the control room ventilation system and thus minimize any radiation dose. Manual isolation capability is also provided.

Isolation from high toxic chemical concentration has been added as a result of the " Control Room Habitability Study" submitted to the NRC in December 1981 in response to NUREG-0737 Item III D.3.4. As explained in Section 3 of this study, ammonia, chlorine, and sulphur dioxide detection capability has been provided. The setpointo chosen for the control room ventilation isolation are based on early detectiog in the outside air supply at the odor threshold, so that the toxic chemical will not achieve toxicity limit concentrations in the Control Room.

The instrumentation that monitors the release of gases from the main condenser offgas system, provides reasonable assurance that the effluents to unrestricted areas will not exceed the guidelines of 10 CFR Part 20. The alarm setpoints for the instruments are provided to ensure that the alarms will occur prior to exceeding the limits of 10 CFR 20.

4.2 SURVEILLANCE REQUIREMENTS BASES Surveillance requirements for the instrumentation in Technical Specification Section 3.2/4.2 are selected in order to demonstrate proper function and operability. The surveillance intervals can be determined by different means, such as, 1) operating experience, 2) good engineering judgement, 3) reliability analyses, or 4) other analyses that are found acceptable to the NRC.

Reactor water level instruments 1(2)-263-73A & B, HPCI high steam flow instruments 1(2)-2352 & 1(2)-2353, and HPCI steam line low pressure instruments 1(2)-2389A-D have been modified to be analog trip systems. The analog trip system consists of an analog sensor (transmitter) and a master / slave trip unit setup which ultimately drives a trip relay. The frequency of calibration and functional testing for instrument loops of the analog trip system has been established in Licensing Topical Reoort NEDO- 21617-A (December 1978) . With the one-out-of-two taken twice logic, NEDO-21617-A states that each trip unit be B 3.2/4.2-7 I

l QUAD CITIES UNITS 1 & 2 DPR-29 & DPR-30 subjected to a calibration / functional test frequency of one month. This monthly calibration / functional test f requency has been extended to quarterly by the analyses contained in NEDC-31677P for trip units in analog trip systems. An adequate calibration / surveillance test interval for the transmitter is once per operating cycle.

The adiation monitors in the ventilation duct and on the re;% ling floor which initiate reactor building ventilation system isolation, control room ventilation system isolation, and standby gas treatment operation are arranged in two one-out-of-two logic systems. The bases given above for the rod blocks apply here also and were used to arrive at the functional testing frequency.

Based on experience at Dresden Unit 1 with instruments of similar design, a testing interval of once overy 3 months has been found to be adequate.

The automatic pressure relief instrumentation can be considered to be a one-out-of-two logic system, and the discussion above applies to it also.

The instrumentation which is required for the post accident condition will be tested and calibrated at regularly scheduled intervals. The basis for the calibration and terting of this instrumentation is the same as was discussed alove for the reactor protection system and the emergency core cooling systems.

itiation of the emergency core cooling system, control rod block and standby gas treatment systems. The objectives of the specifications are (1) to assure the effectiveness of the protective instrumentation when required by preserving its capability to tolerate a single failure of any component of such systems even during periods when portions of such systems are outMD service for maintenance and (2) to prescribe the tri settings required to assure adequate performance.

It should be noted that the setpoints of other instrumentation, where only the high or low end of the setting has a direct bearing on safety, are chosen at a level away from the normal operating range to prevent inadvertent actuation of the safety system involved and exposure to abnormal situations.

Isolation valves are installed in those lines that penetrate the primary containment and must be isolated during a loss-of coolant accident so that the radiation dose limits are not exceeded during an accident condition.

Isolation from high toxic chemical concentration has been added as a result of the " Control Room Habitability _5tudy" submitted to the NRC in December 1981 in response to NUREG-0737 Item III D.3.4. As explained in Section 3 of this study, ammonia, chlorine, and sulphur dioxide detection f capability has been provided. The setpoints chosen for the control room ventilation isolation are based on early detection in the outside air supply at the odor threshold, so that the toxic chemical will not achieve toxicity limit concentrations in the Control Room.

-DPR-29 4.2 SURVEILLANCE REQUIREMENTS BASES T e instrumentation listed in Table 4.2-1 will be functionally tested anf ca ibrated at regularly scheduled intervals. Although this instrument 4 tion is et generally considered to be as important to plant safety as the/

reac r protection system, the same design reliability goal of 0.99 9 is genera ly applied for all applications of one-out-of-two taken twi logic.

Therefe e, on-off sensors are tested once every 3 months and bist le trips associat with analog sensors and amplifiers are tested once eek.

Those instr ents which, when tripped, result in a rod block ave their contacts arr ged in a one-out-of-n logic, and all are capa e of being bypassed. For such a tripping arrangement with bypass ca 111ty provided, there is an opt um test interval that should be maintai d in order to maximize the rel bility of a given channel (Reference . This takes account of the fac that testing degrades reliability The optimum interval between test is app ximately given by:

i= -r where:

1= the optimum interval bet en tests, t= thetimethetripcontactsaedigabledfromperformingtheirfunction while the test is in progress 96d r= the expected failure rate of h relays.

To test the trip relays requir that t channel be bypassed, the test made, and the system returned o its ini al state. It is assumed this task requires an estimated 30 mi tes to comple e in a thorough and workmanlike manner and that the relays /iave a failure r te of 10 8 failures per hour.

Using this data and the aFove operation, the ptimum test interval is:

i = 42(0.M =1x1 .iours 10 8

= s 40 days For addition margin a test interval of once per month 11 be used initially.

The sens/s and electronic apparatus have not been included re, as these are ana)og devices with readouts in the control room, and the ensors and elect nic apparatus can be checked by comparison with other li ins uments. The checks which are made on a daily basis are ade ate to as re operability of the sensors and electronic apparatus, and t test ipf.erval given above provides for optimum testing of the relay circ ts.

3.2/4.2-12 Amendment No. 114

QUAD-CITIES OPR-29 e above calculated test interval optimizes each individual channel, c sidering it to be independent of all others. As an example, assume that the e are two channels with an individual technician assigned to each, ach tech dcian tests his channel at the optimum frequency, but the two techna ians are not allowed to communicate so that one can advise th other that hi channel is under test. Under these conditions, it is pos ble for both cha els to be under test simultaneously. Now assume that t technician are required to communicate and that two channels at never tested a t same time.

Forbidding sim taneous testing improves the availability of the smtem over that which woul be achieved by testing each channel indep dently. These one-out-of-n trip ystems wili be tested one at a time in order to take advantage of this herent improvement in availability.

Optimizing each chann independently may not truly timize the system considering the overal rules of system operation, powever, true system optimization is a comple problem. The optimums te broad, not sharp, and optimizing the individual hannels is generally equate for the system.

The formula given above mini zes the unavail ility of a single channel which must be bypassed during esting. The inimization of_the unavailability is illustrated b curve 1 Figure 4.2-1, which assumes that a channel has a failure rate of 1 x 10 hour and 0.5 hour5.787037e-5 days <br />0.00139 hours <br />8.267196e-6 weeks <br />1.9025e-6 months <br /> is required to 3 test it. The unavailability is a int at a test interval i, of 3.6 x 10 hours1.157407e-4 days <br />0.00278 hours <br />1.653439e-5 weeks <br />3.805e-6 months <br />.

If two similar channels are used i a e-out-of-two configuration, the test interval for minimum availability hang as a function of the rules for testing. The simplest case is test ea h one independent of the other.

In this case, there is assumed o be a fin} e probability that both may be bypassed at one time. This c se is shown b curve 2. Note that the unavailability is lower, as xpected for a re ndant system, and the minimum occurs at the same test i erval. Thus, if th two channels are tested independently, the equat n above yields the tes interval for minimum unavailability.

A more usual case is hat the testing is not done in ependently. I" both

! channels are bypas d and tested at the same time, th result is shown in l- curve 3. Note th the minimun. occurs at about 40,000 ours, much longer than for Cases and 2. Also, the minimum is not nearly s low as Case 2, l which indicate that this method of testing does not take ull advantage of the-redundan channel, Bypassing both chanrels for simulta eous testing should be a oided.

l

-The most ikely case would be to stipulatt that one channel be passed, tested and restored, and then immediately following the second annel be bypas ed, tested, and restored. This is shown by curve 4. Note t at there is t true minimum. The curve does have a definite knee, and very little l

l re uction in system unavailability is achieved by testing at a short ihterval than computed by the equation for a single channel.

SIGNIFICANT HAZARDS CONSIDERATIONS AND ENVIRONMENTAL ASSESSMENT EVALUATION PROPOSED TS 3.2/4.2

' PROTECTIVE INSTRUMENTATION"

I EYALUATION. FOR BIGNIFICANT MA2 APD1_99FJilDIEATIDE Proposed Specification 3.2/4.2 Protective Instrumentation The proposed changes provided in this amendmunt requent are made in order to provide a more user friendly document, incorporate desired technical improvements, and to incorporate some improvements from later operating BWRs. These changes have been reviewed by Commonwealth Edison and we believe that they do not present a Significant llazards consideration. The basis for our determination is documented as follows:

BASIS FOR NO SIGNIFICANT ltAZARDS CONSIDERATION Commonwealth Edison has evaluated this proposed amendment and determined that it involves no significant hazards consideration. In accordance with the criteria of 10 CFR 50.92(c) a proposed amendment to an operating licensu involves no significant hazards consideration if operation of the facility, in accordance with the proposed amendment, would not:

1) Involve a significant increase in the probability or consequences of an accident previous' avaluated, because:
a. The proposed changes to Specifications 3.2.A/4.2.A through 3.2.H/4.2.H are made to provide the user with a format that will allow quicker access to needed information and to provide concise LCO, Applicability, Action and Surveillance requirenants. The bland of requirements from the present Quad Cities Technical Specifications and later operating BWRs utilizes proven material and testing techniques.

The proposed changes to Table 3.2-1 include the addition of RCIC Steam Supply Line Low Pressure and HPCI Steam Supply Line Low Pressure isolation functions setpoints that have been a part of the original design basis for the system; however omitted from the Technical Specifications. The proposed setpoints have been evaluated to ensure that isolation will not occur prior to a decreasing reactor pressure assumed in the accident analysis of 150 psig. The remaining changes to Tables 3.2-1 through 3.2-6, and 4.2-1 through 4.2-4 do not alter any established setpoints cr reduce the minimum operable channels por trip system requirements.

Since the proposed changes are applicable for the Quad cities plant and have been utilized on other operating plants, they do not involve a significant increase in the probability or consequences of an accident previously evaluated.

l

' d

_m. ___ _ _ _ _ _ . _ _ _ - _ _ _ _ _

b. The drywell high radiation isolation was added to the plant by design change in order to comply with the requirements of NUREG 0737 recommendations. The inclusion of the_ operability requirements in the technical specifications helps to ensure operability of the drywell high radiation isolation function when required to initiate a Group 2 valve isolation. Since this instrumentation was installed in accordance with design toquirements and has been operating in the plant for several years, the inclusion of operability Tequirements in the technical specifications cannot involve a significant increase in the probability or consequences of an accident previously evaluated. The requirements chosen to help ensure operability are similar to existing technical specification requirements for other similar instruments or for the same radiation sensors that perform a dual role in containment isolation and post accident monitoring.
c. The proposed changes to incorporate the Surveillance Testing Intervals and Allowed out of Service Intervals in Topical Reports HEDC-33677P, NEDC-30936P-A, and NEDC-30851P Supplement 1 do not degrade the reliability of the Isolation, ECCS or Control Rod Block systems, as demonstrated in the Topical Reports and corresponding plant specific analyses. Implementation of the extended surveillance intervals for Channel Functional and Channel Calibration Tests will not be made without factoring in appropriate drift information into the setpoint calculations. The proposed changes to the Channel check frequency increases present testing requirements. Since the changes do not degrade the reliability of the affected systems over present conditions, there is no significant increase in the probability or consequences of an accident previously evaluated.

I

d. 1ue NRC issued Generic Letter 89/01 on January 31, 389, in order to allow the technical specification provisions for the Radiological Effluent Technical Specifications (RETS) to be relocated to the Administrative Controls section of the technical specjfications (programmatic requirements) and to the ODCM or PCP (procedural details). New programmatic controls for radioactive effluents and radiological l environmental monitoring are relocated to Section 6.0 l of the technical specifications to conform to the l

regulatory requirements of 10 CFR 20.106, 40 CFR Part i 190, 10 CFR 50.36a, and Appendix I to 10 CFR Part 50.

l Tho proposed changes to Section 3.2/4.2 of the Quad

Cities technical specifications relocates the l

provisions of present Tables 3.2-5, 3.2-6. 4.2-3, and l

4.2-4 and the provisions of Specifications 3.2.G/4.2.G l and 3.2.H/4.2.H to the ODCM. The present requirements

q for the SJAE are retained in the technical -

specifications in accordance with GL 89-01 guidelines.

The relocation of the present technical specification requirements is not intended to reduce the level of radiological effluent control. The proposed chango will allow programmatic controls to remain in the (

technical specifications with procedural details controlled by the controls for changos to the ODCH.

Since the proposed changos to implement CL 89/01 provisions moet NRC requirements and retain adequate programmatic controls for RETS in the technical --

specifications, the proposed change does involve a r significant increase in the probability or consequences (

of an accident previously evaluated.

i 2) Create the possibility of a now or difforont kind of accident from any previously evaluated because

a. The changes to Specifications 3.2.A/4.2.A through 3.2.H/4.2.H blend STS requirements with existing Quad Cities requirements to provide a user friendly format and presentation of requirements. The changes proposed to the Tables follow later operating BWR guidelines that are presently being utilized at those plants and have been evaluated and found acceptable for use at Quad Cities. Thorofore, the changos do not create the possibility of a now or different kind of accident from any previously evaluated.

The proposed changes to Tables 3.2-1 through 3.2-6 and 4.2-1 through 4.2-4 implement STS and later operating BWR plant Table arrangements, Notes and Actions. These _

changes are in use at plants with systems similar to those at Quad Cities. The proposed changes do not reduce the number of channels presently required to be operable and maintain operability of systems when required to perform their design function.

b. The drywell high radiation isolation function provides a closure signal to only the Gr,oup 2 isolation valves.

The addition of the operability requirements for this isolation function to the technical specifications does not affect any other accidents or transients other than primary containment isolation which is analyzed.

Therefore, the proposed changes to the technical specifications does not create the possibility of a now or different kind of accident from any previously evaluated,

c. The proposed changes to incorporate the Surveillance Testing Intervals and Allowed Out of Service Times in the Topical Reports discussed above, do not create the possibility of a new or different kind of accident from any previously evaluated because Isolation System,

_ . . . . . - - - . - - - - . - - - - - - - - - - - - - - - - - - - - - " - - - - ' ' ' ^ ' ' ~ ^ ' ^ ' ^ ^ ^ ^ ^ ^ ~ ~ ^ ^ ^ ^ ~

ECCS, and Control Rod Block System function and reliability is not degraded by these changes. No new modes of plant operation are involved. The implementation of STS and later operating plant Channel Calibration Test Frequenciew will only be made to the extent that the instrumentation drift characteristics allow the interval extensions. The change to STS shiftly 2hannel Checks will increase the frequency of l present testing requirements. I

d. The proposed changes to the Technical Specifications resulting from the implementation of Generic Letter 89/01 follow NRC guidelines for relocating RL'TS l procedural requirements to the ODCM and programmatic  !

requirements to Section 6.0 of the technical specifications. Since the present level of radiological effluent monitoring is maintained by the proposed change, the proposed change does not cruate

.e possibility of a new or different kind of accident from any previously evaluated.

3) Involve a significant reduction in the margin of safety because:
a. The changes to Specifications 3.2.A/4.2.A through 3.2.H/4.2.H implement an STS type of format while retaining the present two column layout. This two column layout has been in use at Quad Cities since initial licensing and is preferred by the majority of the technical specification users at the plant. The proposed LCO, Applicability, Actions, and Surveillance Requirements are modeled after STS requirements which have been evaluated and found to be acceptable for use at Quad Cities.

The current setpoints for the low steam pressure isolation functions of HPCI and RCIC are 90 psig and 50 psig respectively. The proposed setpoints of 100 for HPCI and 60 for RCIC are consistent with current methodologies for setpoint determinations and ensure that the systems will remain operable as assumed in the accident analysis and isolate when no longer required.

The remaining changes to the Tables in Section 3.2/4.2 follow proven STS guidelines or provisions that have been implemented at other operating BWR plants. These changes have been evaluated for use at Tuad Cities with a determination that implementation at the plant will not involve a significant reduction in the margin of safety,

b. The proposed change to add the drywell high radiation icolation function to the technical specifications completcs the listing for the Primary Containment Group 2 isolation signals. The additions to the technical

_ ._. m _ . _

specifications of this signal and the inclusion of the Reactor Building Ventilation Exhaust Duct Radiation ,

Monitor in Table 4.7-1 will help to ensure operability '

of tLese isolation functions when required and thus cannot involve a significant reduction la the margin of safety.

c. The proposed changes based on the three General Electric Topical Reports decreases testing for the affected instruments in the Isolation, ECCS, and control Rod Block Systems. Allowed out of service times are increased for the affected systems as a result of the Topical Reports analyses. However, the requested changes do not degrade the reliability of the affected systems and thus the margin of safety is preserved. The results of the topical reports have been.found acceptable for plant use by NRC SERs with the stipulation that setpoint drift over the increased testing interval be conridered it setpoint calculations. Quad cit os vill consider the additional drift in the setpoint calculations before implementing ~

, the exter.ded surveillance testing Intervals and while the extended intervals are in use for both the Channel Functional and Channel Calibration tests. The changes proposed to the Channel Check frequencies will increase '

present testing requirements. Therefore, the changes do not involve a significant reduction in the margin of ,

safety.

d. The proposed implementation of the guidelines of Generic Letter 89/01 retains required RETS programmatic controls in Section 6.0 of the technical specifications and specific procedural controls in the ODCM. As such, the present margins of safety are preserved and the changes do not involve a significant reduction in the margin of safety.

LNVIRONMENTAL; ASSESSMENT EVALUATION PROPOSED SPECIFICATION SBCTION 3.2/4.2 PROTECTIVE INSTRUMENTATION Commonwealth Edison has evaluated the proposed amendment in accordance with the requirements of 10 CFR 51.21 and has de+ 3rmined that the aRendacat meets the requirements for categorical exclusion as specified by 10 CFR Ul.22 (c) (9) .

Commonwealth Edison has detarmined that the amendment involves no significant hazards consideration, there is no significant change in the types or significant increase in the amounts of any effluent that may be released offsite, and there is no significant increase in individual or cumulative occupational radiation exposure.

The proposed amendment does not modify the existing facility and does not involve any new operation of the plant. As such, the proposed amendment does not involve any change in the type or significant increases in effluents, or increase individual or cumulative accupational radiation exposure. The proposed amendment co Section 3.2/3.2, " Protective Instrumentation",

contains administrative changes such as including appropriate applicability statements within the specifications to define the applicability during operating modo and the required actions to be implemented in the event tnat specification cannot be net. The information is consistent with the Standard Technical Specifications or later operating plants. In aidition, some existing requirements have been updated and new .equirements added to reflect the Standard Technical Specifications er later operating plant requirements.

SUMMARY

QUAD CITIES TECHNICAL SPECIFICATION UPGRADE PROGRAM The Quad Cities Technical Specification Upgrade Program was conceptualized in response to lessons learned from the Dresden Diagnostic Evaluation Team inspection and the frequent need for Technical Specification interpretations. A comparison of the existing Quad Cities Technical Specification and, Standard Technical Specifications and later operating plants' Technical Specification provisions was conducted to identify potential improvements in clarifying requirements and to identify requirements which are no longer consistent with current industry practicos. The comparison review identified approximately one-hundred and fifty suggested improvements. The Technical Specification Upgrade Program was not intended to be a complete adoption of the Standard Technical specifications. Overall, the

' Quad Cities custom Technical specifications provide for a safe operation of the plant and, therefore, only an upgrade was deemed appropriate.

The comparison study revealed a mix of recommended upgrades which included the relaxation of certain existing Technical Specification requirements, the addition of surveillances, the removal-of allowances which would no longer be allowed under new plant licensing, and better definition of appropriate action requirements in the event a Limiting Condition for Operation cannot-be met. The Technical Specification Upgrade Program also implements NRC recommended line item improvements to the Technical Specifications which were issued under Generic 7,etters.

In response to-an NRC recommendation, the Unit 1 and Unit 2 Technical Specifications are combined into one document. To accomplish the combination of the Units' Technical Specifications, a comparison of the Unit 1 and 2 Technical Specifications was performed to identify any technical differences. The technical differences are identified in the proposed amendment package for each section.

The Technical Specification Upgrade Program was identified as a Station top priority during the development of Quad Cities Station's Performance Enhancement Program (PEP). The Technical Specification Upgrade Program's goal is to provide a better tool to Station personnel to implement their responsibilities and to ensure Quad Cities Station is operated in accordance with current industry practices. The upgraded specifications provide for more safe and reliable operation of the plant. The program improves the operator's ability to use the Technical Specifications by more clearly defining Limiting Conditions for operations and required actions. The most significant improvement to the specifications is the addition of equipment operability requirements during shutdown conditions.

DESCRIPTION OF CHANGES Proposed TS 3.9/4.9

' AUXILIARY ELECTRICAL SYSTEMS'

1 DESCRIPTION OF PROPOSED AMENDMENT REQUEET Proposed Specification 3.9/4.9 Auxiliary Electrical Systems The changes proposed in this amendment request are made to 1) improve the understanding and usability of the present technical specifications, 2) incorporate technical improvements, and 3) include some provisions from later operating BWR plants.

An item by item description of the proposed changes requested is provided below. The Summary of Changes section can be referred to in order to reference back to a given change and its affected page.

GENERIC CHANGES Item 1 The present Quad Cities technical specifications contain Applicability and Objective statements at the beginning of most sections. These statements are generic in nature and do not provide any useful information to the user of the technical specifications. The proposed change will delete the Objective statement and provide Applicability statements within each specification similar to the STS. The proposed Applicability statement to be included in each specification will include the Reactor Modes or other conditions for which the LCO must be satisfied.

Item 2 The changes proposed in this item will provide an STS type of format while retaining the present two column layout. The present format does not provide a separation of LCO, Applicability, and Action requirements that are easily understood and identified.

The two column layout has been utilized at Quad Cities since initial licensing of the plant and is preferred by the plant over the single column STS layout.

SPECIFIC CHANGES Item 1 The proposed changes described in Item 1 involve the rewrite of present Specification 3.9.A/4.9.A, Normal and Emergency A-C Auxiliary Power, into two Specifications; 3.9.A/4.9.A, A.C.

Sources - Operating, and 3.9.E/4.9.E, Onsite Power Distribution Systems - Operating using an STS format. The proposed LCO for Specification 3.9.A is taken from present provisions in Specifications 3.9.A and 3.9.D. Proposed LCO 3.9.A requires two I

offsite lines, associated transformers and buses to be operable along with the Unit and Unit 1/2 diesel generators with a minimum of 10,000 gallons of diesel fuel on site. The present Applicability for the Normal and Emergency A-C Auxiliary Power sources is before making the reactor critical which corresponds to Operational Modes 1 and 2. In order to address the Hot Shutdown condition (or Operational Mode 3) concerns for required operable A.C. Sources, Operational Mode 3 is added to proposed Specification 3.9 A in accordance with STS guidelines. Present Specification 3.9.E.2 provisions, that allow 1-1/2 hours for diesel generator maintenance without declaring the diesel inoperable, are added to the proposed Applicability for 3.9.A.

Proposed Action 3.9.A.1 is based on present provisions in 3.9.C.1 and addresses the condition where one of the required offsite lines is inoperable. Proposed Action 3.9.A.2 is based on present provisions in 3.9.C.2 and addresses the condition where both of the required offsite lines are inoperable. Since present Specifications 3.9.C.1 and 3.9.C.: do not contain specific reactor shutdown time frames if the remedial steps are not met, STS reactor shutdown time frames of 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br /> to Hot Shutdown and another 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> to Cold shutdown are added. Proposed Action 3.9.A.3 is based on present provisions in 3.9.E.1 and part of 4.9.E.1 to address the condition where either the Unit or Unit 1/2 diesel generator is inoperable. The part added from present 4.9.E.1 requires demonstration of operability of the remaining operable diesel generator, immediately and daily thereafter.

Present reactor shutdown provisions to initiate an orderly shutdown and to be in the cold condition within 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> is replaced with the STS provisions to be in at least Hot Shutdown within 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br /> and in Cold Shutdown within the next 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br />.

The STS reactor shutdown time frames are being used throughout the revised Quad Cities Technical Specifications. Present Specifications do not address the condition where both the Unit and Unit 1/2 diesel generators are inoperable. Proposed Action 3.9.A.4 is added from the STS to address the condition where both diesel generators are inoperable and requires verification of operability of both of the required offsite lines and restoration of one diesel generator within 2 hours2.314815e-5 days <br />5.555556e-4 hours <br />3.306878e-6 weeks <br />7.61e-7 months <br /> or the reactor is required to be shutdown. Both inoperable diesel generator - are required to be restored to operable within 7 days from initic loss or the reactor is required to be shutdown. Seven days is used as the allowed out of service period in proposed action 3.9.A.4 instead of tne STS guideline of 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br /> since present specifications use the 7 day allowance for one diesel generator being inoperable.

Proposed Surveillance Requirements for A.C. Sources - Operating are taken from present provisions. Proposed SR 4.9.A.1 for offsite power lines is taken from present SRs 4.9.A.2 and 4.9.A.3.

Proposed SR 4.9.A.2 for the emergency diesel generators is developed from present SRs 4.9.A.1 and 4.9.D and incorporates the STS, minimum 60 minute, under load, test duration for the monthly emergency diesel generator runs. Proposed SR 4.9.A.3 for the refueling outage interval testing of the emergency diesel I

i 4

generators is taken present SR 4.9.E.2.

Present Specifications 3.9.A.4.a and 3.9.A.4.b are used in the development of proposed Specification 3.9.E/4.9.E, Onsite Power Distribution Systems - Operating. The LCO scope of this specification is defined by present provisions for A.C. power distribution, as 4150-volt buses 13-1 and 14-1 for Unit 1, and 23-1 and 24-1 for Unit 2; and, 480-volt buses 18 and 19 for Unit 1, and 28 and 29 for Unit 2. Present technical specifications do not address D.C power distribution systems. In accordance with STS l guidelines, D.C. 125-volt buses and 250-volt motor control centers '

are added. These include Unit 1, Division 1, 125-volt Turbine Building Buses 1A, 1A1, lA2 and Reactor Building Distribution j Panel 1. For Unit 2, Division 2, 125-volt Turbine Building Reserve Buses 1B, 1B1, 1B2 and Turbine Building Main Bus 2A are i included. Motor Control Centers for 250-volt D.C. that are required operable include Reactor Building MCCs 1A and 1B for Unit 1; and either Turbine Building MCC 1 for Unit 1 or Turbine Building 250-volt MCC 2 for Unit 2. The energization of the specified D.C. distribution systems provides necessary power to systems that are r~equired operable in Operational Modes 1,'2, and

3. Proposed Applicability of Operational Modes 1, 2, and 3 implements present intent of 3.9.A such that buses are energized before making the reactor critical, and STS guidelines. Proposed Actions for the Onsite Power Distribution Systems -Operating are added from STS guidelines since no present provisions exist. The proposed action allows 8 hours9.259259e-5 days <br />0.00222 hours <br />1.322751e-5 weeks <br />3.044e-6 months <br /> to re-energize a required A.C.

distribution system or initiate shutdown of the reactor. With one of the required D.C. distribution systems inoperable, 2 hours2.314815e-5 days <br />5.555556e-4 hours <br />3.306878e-6 weeks <br />7.61e-7 months <br /> is allowed to re-energize the system or a reactor shutdown is required. Present SR 4.9.A.4 requires a daily check of the Unit engineered safety features _4160-volt and 480-volt buses. This present SR is replaced with the STS SR which is a seven day test for verification of energization of the required buses by checking for correct breaker alignment and proper voltage. The STS seven day test frequency in conjunction with the added STS Action provisions help to provide assurance of required onsite power distribution system operability.

Present specifications do not contain provisions for Onsite Power Distribution Systems while the plant is shutdown or while conducting handling of irradiated fuel in the secondary containment. Proposed Specification 3.9.F/4.9.F addresses these conditions and ados requirements based on STS guidelines.

Proposed LCO 3.9.F includes requirements for one A.C. and one D.C.

distribution system to be operable during Applicability of Operational Modes 4, 5 and when handling irradiated fuel in the secondary containment. Proposed Action 3.9.F.1 specifies that with less than the required systems energized, Core Alterations are suspended and handling of irradiated fuel in the secondary containment and operations with a potential for draining the reactor vessel are stopped. Proposed Action 3.9.F.2 implements STS guidelines by providing an exception to the reactor shutdown provisions of proposed Specification 3.0.C. This proposed

exception applies only to the condition of moving irradiated fuel in the secondary containment when all fuel has been removed from the reactor vessel and the plant is not considered to be in any Operational Mode. Proposed Surveillance Requirement 4.9.F repeats the test requirements in 4.9.E for Onsite Power Distribution Systems - Operating.

Item 2 This item describes the rewrite of present Specification 3.9.B/4.9.B, Station Batteries, into proposed Specification 3.9.C/4.9.C, Station Batteries - Operating. Proposed LCO 3.9.C is based on present provisions and requires operability of the Unit 24/48-volt batteries, the two station 125-volt batteries, the two station 250-volt batteries, and one battery charger for each required battery. The proposed Applicability of Operatjonal Modes 1, 2, and 3-implements present intent of before the reactor can be made critical and STS guidelines which also includes conditions where the reactor is in the Hot Shutdown Operational Mode.

Proposed Action 3.9.C.1 is based on present provisions in 3.9.C.3 and requires that with one of the two 125/250-volt battery systems inoperable, three days is allowed for restoration and then the reactor is required to be shutdown. Proposed Action 3.9.C.2 is based on STS guidelines to address the condition where battery systems are inoperable other than those hddressed in proposed Action 3.9.C.1. Proposed Action 3.9.C.2 allows 2 hours2.314815e-5 days <br />5.555556e-4 hours <br />3.306878e-6 weeks <br />7.61e-7 months <br /> to restore the inoparable systems and then the reactor is required to be shutdown..

Proposed SR 4.9.C.1 is taken from STS guidelines and replaces present daily status checks in 4.9.C with weekly checks by verifying breaker alignment and voltage. Weekly verification of system str,tus is adequate since breaker alignment should not change and major voltage changes will be noticed by routine operator rounds and chccks if they occur within the 7 day test period.- Proposed SRs 4.9.C.2 and 4.9.C.3 are taken from present provisions in SRs 4.9.B.1 and 4.9.B.2. Proposed SR 4.9.C.4, modified to reflect STS guidelines by requiring performance of battery service tests at refueling outage intervals, implements the intent of present SR 4.9.B.3 which prescribes performance of rated load discharge to:sts. Present Quad Cities Technical Specifications do not contain surveillance requirements for battery chargers. Therefore, new SR 4.9.C.5, based on STS guidelines, is proposed in order to ensure adequate charger performance during the operating cycle. Also, new SRs 4.9.C.6 and 4.9.C.7, associated with battery performance discharge tests, incorporate STS provisions and are intended to determine overal'1 batterv legradation due to age and usage.

Present Quad Cities Technical Specifications do not contain provisions for Station Batteries during shutdown and when handling irrhdiated fuel in the secondary containment. Proposed Specification 3.9.D/4.9.D is proposed from STS guidelines in order to add necessary requirements for these conditions. Proposed LCO 3.9.D requires operability of the Unit 24/48-volt batteries, one station 125-volt battery, and one battery charger for each required battery. The proposed LCO provides the minimum level of Station Battery operability during the proposed Applicability of Operational Modes 4, 5 and when handling irradiated fuel in the secondary containment. Proposed Action 3.9.D.1 requires that with less than the required D.C. electrical power sources operable, Core Alterations be suspended and handling of irradiated fuel in the secondary containment and operations with a potential for draining the reactor vessel be stopped. Similar to proposed Specification 3.9.F, Onsite Power Distribution Systems - Shutdown, proposed Action 3.9.D.2 is added to provide a necessary exception to the reactor shutdown provisions of proposed Specification 3.0.C. This exception will only apply when handling irradiated fuel in the secondary containment when all fuel is removed from the reactor and the plant is not is any Operational Mode.

Proposed SR 4.9.D references SR 4.9.C, Station Batteries -

Operating, for required testing.

Item 3 Item 3 describes the inclusion of present provisions in Specification 3.9.C/4.9.C, Electric Power Availability, into cther specifications proposed for Section 3.9/4.9. The Summary of Changes provides the list of present provisions and their new locations.

Item 4 Item 4 describes the inclusion of present provisions of Specification 3.9.D/4.9.D, Diesel Fuel, into other proposed Specifications in Section 3.9/4.9. The Summary of Changes lists the proposed relocation of requirements.

Item 5 Item 5 describes the inclusion of present provisions of Specification 3.9.E/4.9.E, Diesel-Generator Operability, into other proposed Specifications in Section 3.9/4.9. The Summary of Changer lists the proposed relocation of requirements. Part of present SR 4.9.E.1 is deleted which contains Action provisions with one diesel generator inoperable such that all low-pressure core cooling systems and all loops of the containment cooling modes of the RHR system associated with the operable diesel generator shall be demonstrated to be operable immediately and daily thereafter. Proposed Action 3.9.A.3 includes a provision to require operability of the ECC systems associated with the operable diesel generator but does not contain the present provision in SR 4,9.E.1 to demonstrate such operability. As described in proposed changes to Section 3.5/4.5, verification of operability of systems is an adequate determination of operability without having to actually operate the affected systems. Also, present SR 4.9.E.1 requires the operable diesel generator to be

demonstrated operable immediately and daily thereafter and this part is included in proposed Action 3.9.A.3.

Present Specification 3.9.E.3 addresses diesel generator requirements in Operational Modes 4 and 5. Proposed Specification 3.9 B/4.9.B, A.C. Sources - Shutdown, addresses the present provisions in 3.9.E.3 and adds STS guidelines. In addition to the present requirement of one operable diesel generator, proposed LCO 3.9.B also includes the STS provision for operability of one offsite power line including associated switchgear and transformers, capabic of carrying power to the Unit. Present Applicability in 3.9.E.3 is in the Cold Shutdown or Refueling mode, whenever any work is being done which has the potential for draining the vessel, secondary containment is required, or a core or containment cooling system is required. Proposed Applicability is Operational Modes 4, 5, and when handling irradiated fuel in the secondary containment. The proposed Applicability includes the conditions of the present Applicability since the specification is applicable during all operations in Operational Modes 4 or 5. Proposed Action 3.9 B is added from STS guidelines since no present provisions exist. The proposed Action requires that with less than the required A.C. electrical power sources operable, core alterations and handling of irradiated fuel in the secondary containment are suspended, operations with a potential to drain the reactor vessel and crane operations over the spent fuel storage pool whoo fuel assemblies are stored therein are stopped. In addition, the proposed Action requires that when in Operational Mode 5 with the water level in the spent fuel storage pool less than 33 feet, corrective action is required immediately to restore the required power sources to operable status as soon as practical. Proposed SR 4.9.B references the SRs in 4.9.A as required testing for the operable A.C. Sources.

Item 6 Present Specification 3.9.F/4.9.F, Reactor Protection Bus Power Monitoring System, is rewritten as proposed Specification 3.9.G/4.9.G. Proposed LCO 3.9.G is taken from present provisions that require two RPS electric power monitoring channels fer each inservice RPS MG set or alternate power source. Present Applicability of all Operational Modes except Shutdown is replaced with the STS provision of at all times. The proposed change to the Applicability ensures that at all times when an RPS MG set or alternate power source is in operation, that proper controls over frequency and voltage are maintained. Present Action provisions are retained.

Present SR 4.9.F.1.a requires a functional test of the RPS Bus power monitoring system instrumentation at least once per 6 months. This present SR is proposed to be changed to allow performance of the test in Cold Shutdown in order to avoid the potential of tripping an RPS MG set at power and the potential for inadvertent reactor scrams. This testing method has been implemented at some later operating BWRs with RPS systems similar

to Quad cities and has been demonstrated to provide adequate assurance of system operability. The remaining SRs for proposed 4.9.G implement present provisions in 4.9.F.

Item 7 The proposed changes to the Bases for Specification 3.9/4.9 are limited to those necessary to implement the proposed changes discussed in Items 1 through 6 above.

QUAD CITIES UNITS 1 & 2 DPR-29 & DPR-30 3.9 LIMITING CONDITIONS roR OPERATION BASES A. The general objective of this specification is to assure an adequate sourco of electrical power to operato the t.oxiliarios during plant operation, to -

operato facilitics to cool and lubricate the plant during shutdown, and to oporato the engineered safety features following an accident. There are two sourcos of electrical energy available, i.e.,

the 345-kV transmission system and the diesel generators.

The ACTION requirements specified for the levels of degradation of the power sources provido restriction upon continued facility operation commensurate with the lovel of degradation. ACTION statements have been included in the specificaticn to cover all situations where either ono AC sourco or a combination of two AC uources are inoperable.

ACTION statement 4 is intended to be followed to completion once entered and should not be exited until both AC sources are restored. The OPERABILITY of the power sources is consistent with the initial condition assumptions of the accident analyses and is based on maintaining at least one train of the onsite A.C. and D.C. power sources and associated distribution systems OPERABLE during accident condit # "ns coincident with an assumed loss of offsi ) wor and single failure of one of the two onsito C. sources.

Auxiliary power for the Unit is supplied from two sources, either the Unit auxiliary transformer or the Unit reserve auxiliary transformer. Both of these transformers are sited to carry 100% of the auxiliary load. If the reserve auxiliary transformer is lost, the unit can continue to run for 7 days, since the Unit auxiliary transformer is available and both diesel generators are operational. A 7-day period is provided if one source of of fsite power is lost. This period is based on having two diesels operable which are adequate to handle an accident assuming a single failure. In addition, auxiliary power from the other unit can be obtained through the 4160-volt bus tie. If both offsite lines are lost, power is reduced to 40% of rated so that the turbine bypass system could accept the steam flow without reactor trip, should the generator be separated from the B 3.9/4.9-1

QUAD CITIES UNITS 1 & 2 DPR-29 & DPR-30 system or a turbino trip occur. In this condition, the turbino-generator is capable of supplying house load and ECCS loud if necessary through the unit auxiliary transformer. If the unit were shutdown on loss of both lines, fewer sources of power would be available than for sustained operation at 40% power.

Attention will to given to restoring normal offsito power to minimize the length of time operation is allowed in a condition where both sources are unavailable.

In the normal mode of operation, the 345-kV system is OPERABLE and two diesel generators are OPERABLE.

One diesel generator may be allowed out of service for a short period of timo to conduct proventativo --

maintenanco provided that power is available from the 345-kV system through a 4160-volt bus tio to supply the emergency buses, and the alternato diesel generator is proven OPERABLE. Offsite power is quito reliable, and in thu last 25 years there has been only one instance in which all offsite power was lost at a Commonwealth Edison Generating Station. When the unit or shared dicsol generator is made or found inoperabib for reasons other than preventative maintenance, the remaining diesel generator and its associated low-pressure core cooling and containment cooling systems, which provide sufficient engineered safety features coulpment to cover all breaks are required to be OPERABLE.

The diesel fuel supply of 10,000 gallons will supply each diesel generator with a minimum of 2 days of full load operation or about 4 days at 1/2 load.

i Additional diesel fuel can be obtained and delivered to the site within an 8-hour period; thus a 2-day supply provides for adequate margin.

B. lho OPERABILITY of the minimum specified A.C. power sources during shutdown, refueling, and when handling irradiated fuel in the secondary containment, ensures that the facility can be maintained in these conditions for extended time periods and that sufficient instrumentation and control capability is available for monitoring and maintaining the unit status.

The electrical power required provides for the maximum availability of power, i.e., one activo offsite source and one backup source of offsito power and the maximum numbers of onsito sources.

D. Tho OPERABILITY of the minimum specified D.C. power sources, during OPERATIONAL MODES 4, 5 and when handling irradiated fuol in the secondary containment, ensures that the facility can be maintained in those conditions for extended timo periods and sufficient instrumentation and control capability is available for monitoring and maintaining the unit status. Requiring OPERABILITY of the minimum specified D.C. power sources when handling irradiated fuel in the secondary containment helps to ensure thet systems nooded to mitigate a fuel handling accident are available. ,

Testing is conducted up to equilibrium operating conditions to demonstrato proper operation at tnese conditions. Tho dicsol will be manually started, synchronized to the bus, and load picked up. The diosol shall bo loaded to at least half load to prevent fouling of the engine.

It is expected that the diesel generator will be run for 1 to 2 hours2.314815e-5 days <br />5.555556e-4 hours <br />3.306878e-6 weeks <br />7.61e-7 months <br />. Diesel onerator experience at other commonwealth Edison generating stations indicates that the testing frequency is adequato and providos a high reliability of operation should the system be required. In addition, during the test, the generator is synchronized to the offsite power sources and thus not completely indopondent of this source. To maintain the maximum amount of independone:e, a 30-day testing interval is also desirable.

Each dioscl generator. has two air compressors and four air tanks. Two air tanks are piped together to form an air receiver. Each air compressor supplies an air receiver. This arrangement provides redundancy in starting capability. It is expected that the air compressors will run only infrequently.

During the monthly check of the diesel, the receivers will be drawn down below the point at which the compressor automatically starts to check operation and the ability of the compressors to rocharge the receivers. Pressure indicators are provided on each of the receivers.

Following the monthly test of the diesels, the fuel oil. day tank will be approximately half full based -

on the 2-hour test at full load and 205 gph at full load. At the end of the monthly load test of the diesel generators,-the fuel oil transfer pumps will be operated to refill the day tank and to check the operation of these pumps from the emergency source.

The test of the emergency diesel generator during the refueling outage will be more comprehensivo in that it will functionally test the system, i.e., it will check diesel starting, closure of diesel breaker, and sequencing of loads on the diesel. The B 3.9/4.9-5

QUAD CITIES UNITS 1 & 2 DPR-29 & DPR-30 diesel will be started by simulation of a loss-of-coolant accident. In addition, an undervoltage condition will be impos6d to simulate a loss of offsite power. The only load on the diesel is that due to friction and Windage and a small amount of bypass flow on each pump.

Periodic tests between refueling outages verify the ability of the diesel to run at full load and the core and containment cooling pumps to deliver full flow. Periodic testing of the various components plus a functional test at the refueling interval are sufficient to maintain adequate reliability.

The diesel fuel oil quality must be checked to

-ensure proper operation of the diesel generators.

Water content should be minimized, because water in the fuel would contribute to excessive corrosion of the system, causing decreased rollability. The growth of micro-organisms results in slime formations, which are one of the chief causes of jellying in hydrocarbon fuels. Minimizing such climes is also essential to assuring high reliability, c&D Although station batteries will deteriorate with time, utility experience indicates there is almost no possibility of precipitous failure. The type of surveillance described in this specification is that -

which has been demonetrated -over the years to provide an indication of a cell becoming irregular or unserviceable long before it becomes a failure.

A. The general objective of this specification is to assure an adequate source of electrical power to operate the auxiliaries during plant operation, to operate facilities to cool and lubricate the plant during  !

The electrical power required provides for the maximum availability of power, i.e. , one active of fsite source and one backup source of of f site power and the maximum numbers of-onsite sources.

C. ~k'u'xiliary power for the Unit is supplied f rom two sources, either the  ;

Unit auxiliary transformer or the Unit reserve auxiliary transformer.

Both of these transformers are sized to carry 100% of the auxiliary-load. If the reserve auxiliary transfouer is lost, the unit can continue to run for 7 days, since the Unit auxiliary transformer is-available and both diesel generators are operational. A 7 day period

  • is provided if one source of offsite power is-lost. This period is based on having two diesels operable which are adequate to handle an accident assuming a single failure. -In addition, auxiliary power f rom

-the.other unit can be obtained through the 4160-volt bus tie. If both of fsite lines are lost, power is reduced to 40% of rated so that the turbine bypass syste'n could accept the steam flow without reactor trirg should the generator be separated from the system or a turbine trip  ;

RVALUATION FOR SIGNIFICANT HAZARDS CONSIDERATION Proposed Specification 3.9/4.9 Auxiliary Electrical Systems The proposed changes provided in this amendment request are made in order to provide a more user friendly document, incorporate desired technical improvements, and to incorporate some improvements from later operating BWRs. These changes ave been reviewed by Commonwealth Edison and we believe that the do not present a Significant Hazard. Consideration. The basis for our determination is documented as follows:

BASIS FOR NO SIGNIFICANT HAZARDS CONSIDERATION Common salth Edison has evaluated this proposed amendment and determined that it involves no significant hazards consideration.

In accordance with the criteria of 10 CFR 50.92(c) a proposed amendment to an operating license involves no significant hazards consideration if operation of the facility, in accordance with the proposed amendment, would not:

1) . Involve a significant increase in the probability or consequences of an accident previously evaluated, because:
a. The Generic Changes to the technical specificntions involve administrative changes to format and azzangement of the material. As such, these changes cannot involve a significant increase in the probability or consequences of an accident previously evaluated.
b. The proposed changes to the present Normal and Emergency A-C Auxiliary Power-specifications include the separation into two specificatio:.s, ; C. Sources -

Operating and Onsite Power Distributjsn Systems -

Operating. Tha proposed changes involve the incorporation of present provisions ir.co a new format and the integration of S"S guidelines where no present requirements exist or improvements need to be made.

Proposed A.C. Sources - Operating 5pecifications use present provisions for LCO requirements. The proposed LCO requires operability of two independent offsite 345-kV lines with transmission ca= ability to the Unit and operability of both the Unit and Unit 1/2 diesel generators. Present intent is for Applicability in Operational Modes 1 and 2, which is retained, and expanded to include Operational Mode 3 in accordance with STS guidelines. Proposed Actions based on present provisions include those for one or both of the required offsite lines inoperable and those for one diesel generator inoperable. Added from STS guidelines is an

r- 1 i

Action for both diesel generators inoperable. STS reactor shutdown time frames of 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br /> to Hot Shutdown and another 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> to Cold Shutdown are used in the proposed Actions. These proposed reactor shutdown time frames are being implemented throughout the Quad Cities Technical Specifications and have been proven in use at operating BWRs with systems similar to those at Quad Cities. Since present Actions for one or both offsite lines being inoperable do not contain reactor shutdown time frames, reliance on the general provisions of present 3.0.A would result in the same shutdown time frame requirements as proposed from the STS. Proposed Action for one diesel generator inoperable does not contain the present provision to demonstrate the operability of the ECC systems on the remaining operable diesel generator. Verification of operability of the ECC systems is retained and is adequate to assure ECC systems are available without actually running the systems. This change in testing requirements follows similar changes proposed for tne ECC Systems in Section 3.5/4.5 and the Standby Gas Treatment System in Section 3.7/4.7. Proposed SRs for A.C. Sources - Operating implement present provisions. Therefore, the proposed changes do not involve a significant increase in the probability or consequences of an accident previously evaluated.

Proposed Specifications for Onsite power Distribution Systems - Operating are based on present provisions and STS guidelines. Present provisions requiring operability of Unit engineered safety features 4160-volt and 480-volt buses are used in the proposed LCO. Added to the present provisions are requirements, based on STS guidelines, for operability of D.C. distribution systems. The proposed Applicability is operational Modes 1, 2, and 3.which includes present intent and adds operational Mode 3 by STS guidelines. Since no remedial Actions exist in the present specifications, STS guidelines are used which allow 8 hours9.259259e-5 days <br />0.00222 hours <br />1.322751e-5 weeks <br />3.044e-6 months <br /> to-re-energize the inoperable A.C. system and 2 hours2.314815e-5 days <br />5.555556e-4 hours <br />3.306878e-6 weeks <br />7.61e-7 months <br /> to re-energize the inoperable D.C. system or the reactor is required to be shutdown. -Present Surveillance Requirements involve a daily check of Unit engineered safety features buses.

The present SR is replaced with STS guidelines for a weekly test for verification of the energization of required buses by checking for correct breaker alignment and proper voltage. The proposad changes maintain necessary operability of the required electrical buses and implement STS guidelines where none presently exist or where improvements in present requirements can be realized. Since the present level of Unit engineered safety features buses is maintained by the proposed changes, the changes do not involve a significant increase in the probability or conaequences of an

e accident previously evaluated.

The addition of Specification 3.9.F/4.9.F, Onsite Power Distribution Systems - Shutdown, represents new

~}

requirements that are not presently in the technical specitications. Proposed Specification 3.9.F/4.9.F is based on STS guidelines and requires operability of necessary A.C. and D.C. power distribution systems while in Operational Mode s 4, 5 and when handling irradiated fuel in the secondary containment. Proposed Actions require suspension of Core Alterations, handling of irradiated fuel in the secondary containment, and operations with a potential for draining the reactor vessel when required A.C. or D.C systems are not energized. The proposed exception to the provisions of specification 3.0.C only applies to the handling of irradiated fuel in the secondary containment when all the fuel has been removed from the reactor thereby resulting in the plant not being in any Operational Mode. Proposed Surveillance requirements repeat those for Onsite Power Dfstribution Systems - Operating. The proposed addition of Specification 3.9.F/4.9.F represents rerarictions that are not prese;.tly in the technical specifications and helps to orovide assurance of the availability of necessary onsite power distribution systems when requir:pd. Therefore, the proposed addition of these specifications cannot involve a significant increase in the probability or consequences nf an accident previously evaluated.

c. Proposed Changes to A.C. Sources - Shutdown Specifications Present provisions for A.C. Sources while the plant is in Operational Modes 4 or 5 are not complete and need STS provisions to be added. The STS provisions added include requiring, in addition to the present provision of one diesel generator, an offsite power line to be operable while the plant is in Operational Modes 4, 5, and when irradiated fuel is being handled in the secondary containment. STS actions are needed since there are no present remedial Action statements. The added Action provisions will ensure that without the required A.C. Sources, core alterations, handling of irradiated fuel in the secondary containment, operations with a potential for draiaing the reactor vessel, and crans operations over the spent fuel storage pool when fuel assemblies are stored therein, are suspended. The proposed Actions also require restoration of the inoperable A.C. Sources as soon as practical when in Operatienal Mode 5 and the spent fuel storage pool water level is less than 33 feet. The Surveillance Requirements for A.C. Sources - Shutdown are the same as for A.C. Sources - Operating. The proposed changes

retain the intent of the present provisions and add restrictions on operations that are not currently in the Specifications. Therefore, the proposed changes do not involve a significant increase in the probability or consequences of an accident previously evaluated,

d. Proposed Changes to the Station Batteries Specifications Present LCO provisions are maintained for proposed Station Batteries - Operating Specification, 3.9.C/4.9.C, and require operability of the Unit 24/48-volt batteries, two station 125-volt batteries, two station 250-volt batteries, and one battery charger for each required battery. Present Applicability of l battery operability before the reactor can be made i critical, is retained and expanded to include )

Operational Modes 1, 2, and 3. Present Actions for the l 125/250-volt batteries are retained and STS guidelines are used to add an Action provision to address the inoperability of the other battery systems. STS reactor shutdown time frames of 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br /> to Hot Shutdown and another 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> to Cold Shutdown are added to the Actions in order to implement consistent, proven shutdown provisions throughout the Quad Cit ies Technical Specifications. STS surveillance requirements are added  !

to replace present daily checks of availability of electric power in SR 4.9.C with weekly verifications of breaker alignment and voltage. New battery charger surveillance requirements, based on STS guidelines, are proposed in order to ensurc adequate charger performance during the operating cycle. Also, new surveillance requirements incorporating STS provisions and associated with battery performance discharge tests, are intended to determine overall battery degradation due to age and usage. The proposed changes enhance present provisions-and help to ensure operability of the Station Batteries when they are required to be operable. Therefore, the proposed changes do not involve a significant increase in the probability or consequences of an accident previously evaluated.

The proposed addition of Specification 3.9.D/4.9.D, Station Batteries - Shutdown, represents requirements that do not presently exist in Quad Cities Technical Specifications. These new provisions are based on STS guidelines and require operability of minimum D.C electrical power sources in Operational Modes 4, 5 and when handling irradiated fuel in the secondary containment. Proposed Actions require suspension of Core Alterations, handling of irradiated fuel in the secondary containment and operations with a potential for draining the reactor vessel, when less than the required D.C. systems are operable. Also added is an e:meption to the provisions of Specification 3.0.C.

This exception will apply only to handling of irradinted fuel in the secondary containment during the condition where all fuel is removed from the reactor vessel and

'-] the reactor is in no Operational Mode. Propored Surveillance Requirements for 4.9.D reference the SRs for 4.9.C, Station Batteries - Operating. The proposed addition of Specification 3.9.D/4.9.D adds restrictions not presently in the Quad Cities Technical Specifications and helps to ensure operability of necessary D.C. power sources in the shutdown condition.

Therefore, the proposed changes do not involve a significant increase in the probability or consequences of an accident previously evaluated.

e. Proposed Changes to tae Reactor Protection Bus Power Monitoring System Specifications Present provisions for RPS Bus Power Monitoring are improved with STS and later operating plants' requirements. The present LCO requirements are retained and require two instrumentation channels for each inservice RPS MG set or inservice alternate power source. The present Applicability of except when the reactor is in the Shutdown Mode is changed to "At all times." The proposed change in the Applicability requires proper controls to be maintained over frequency and voltage any time a RPS MG set or alternate power source is in operation. Present Action and Surveillance Requirements are retained except for channel functional testing pr0 Visions. Present SRs require a channel functional test at least once per six months.

Performance of this channel functional test when the reactor is operating increases the potential for inadvertent reactor trips. Some later operating BWR plants have modified this testing provisicn to allow the '

channel functional test to be performed each time the reactor is in Cold Shutdown for a period of more than 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br />, unless the test has been performed in the last six months. Quad cities has evaluated this proposed change to the channel functional testing frequency and found it to be accentable for use based on system design similarities with later operating plants and demonstration by use at the later operating plants that necessary system operability is maintained. Present setpoints and LCOs are maintained by the proposed changes. The changes add more restrictive Applicability requirements and modify SR requirements to help avoid inadvertent reactor trips while maintaining necessary system operability. Therefore, the proposed changes do not involve a 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 because:
a. Since the Generic Changes proposed to the technical specifications are administrative in nature, they cannot create the possibility of a new or different kind of accident from any previously evaluated,
b. The proposed changes for Quad Cities Technical Specification Section 3.9/4.9 are based on present.

provisions and STS guidelines or later operating BWR plants' changes which have received NRC approval. These proposed changes have been reviewed-for acceptability at

-the_ Quad cities Nuclear Station considering similarity of system or component design versus the STS or later operating BWRs. No new modes of operation are introduced-by the proposed changes, considering the acceptable Operational Modes in present specifications, the STS, or later operating BWRs. The proposed changes do not modify _ existing setpoints or design-ansumptions for system or component operation. Surveill ance requirements are changed to-reflect-improvements in technique,_ frequency of performance or operating experience at later plants. Proposed changes to Action statements in many places add requirements that are not in the present technical specifications or adopt requirements that have been used successfully at other operating BWRs with designs similar to Quad Cities. The

-proposed changes either maintain at-least the present.

level-of operability.or adopt relaxations to present requirements.which still-provide a proven. acceptable level of_ operability. Therefore, the proposed changes do not create the possibility of a new or different kind of accident.from any previously evaluated.

3) Involve a significant reduction in-th margin of safety

, because:

a. Due to the administrative nature of the Generic Changes, they do not-involve a significant reduction in the margin of safety,
b. The proposed changes to Technical-Specification Section 3.9/4.9 implement present requirements, the intent of present requirements, or provisions that have been found

~

acceptable for use on other operating BWRs with system

-designs similar to that at Quad' Cities. The proposed changes are intended to improve readability, usability,

-and the understanding of: technical specification requirements while maintaining acceptable levels'of safe operation. The proposed' changes-have been evaluated and found to be acceptable for use at Quad Cities based on system design, safety analysis requirements and operational performance. Since the proposed changes are

' based on NRC accepted provisions at other operating plants that are applicable at Quad cities and maintain necessary levele of system, component or parameter operability, the proposed changes do not involve a significant reduction in the margin of safety.

ENVIBONMENTAL ASSESSMENT EVALUATION PROPOSED SPECIFICATION SECTION 3.9/4.9 AUXILIARY ELECTRICAL SYSTEMS Commonwealth Edison has evaluated the proposed amendment in accordance with the requirements of 10 CFR 51.21 and has determined that the amendment meets the requirements for categorical exclusion as specified by 10 CFR 51.22 (c) (9) .

Commonwealth Edison has determined that the amendment involves no significant hazards consideration, there is no significant change in the types or significant increase in the amounts of any effluent that may be released offsite, and there is no significant increase in individual or cumulative occupational radiation exposure.

The proposed amendment does not modify the existing facility and does not involve any new operation of the plant. As such, the proposed amendment does not involve any change in the type or significant increases in effluents, or increase individual or cumulative occupational radiation exposure. The preposed amendment to Section 3.9/4.9, " Auxiliary Electrical Systems",

contains administrative changes such as including appropriate applicability statements within the specifications to define the applicability during operating mode and the required actions to be implemented in the event that specification cannot be met. The information is consistent with the Standard Technical Specifications or later operating plants. In addition, some existing requirements have been updated and new requirements added to reflect the Standard Technical Specifications or later operating plant requirements.
