1.0 DESCRIPTION
Exelon Generation Company, LLC (EGC), requests adoption of Technical Specifications Task Force Traveler 582 (TSTF-582), Revision 0, "Reactor Pressure Vessel Water Inventory Control (RPV WIC) Enhancements," which is an approved change to the Improved Standard Technical Specifications (ISTS), into Clinton Power Station, Unit 1, Dresden Nuclear Power Station, Units 2 and 3, LaSalle County Station, Units 1 and 2, and Quad Cities Nuclear Power Station , Units 1 and 2, Technical Specifications (TS). The Technical Specifications (TS) related to RPV WIC are revised to incorporate operating experience and to correct errors and omissions in TSTF-542, Revision 2, "Reactor Pressure Vessel Water Inventory Control." The proposed changes also include the variation described in TSTF-583 and discussed in Reference 3.
2.0 ASSESSMENT 2.1 Applicability of Safety Evaluation EGC has reviewed the safety evaluation for TSTF-582 provided to the Technical Specifications Task Force in a letter dated August 13, 2020 (Reference 2). This review included a review of the NRC evaluation, as well as the information provided in TSTF-582 (Reference 1). As described below, EGC has concluded that the justifications presented in TSTF-582 and the safety evaluation prepared by the NRG are applicable to Clinton Power Station , Unit 1, Dresden Nuclear Power Station, Units 2 and 3, LaSalle County Station, Units 1 and 2, and Quad Cities Nuclear Power Station, Units 1 and 2, and justify this amendment for the incorporation of the changes to these plants TS.
EGC verified that the required ECCS injection/spray subsystem can be aligned and the pump started using relatively simple evolutions involving the manipulation of a small number of components. These actions can be performed in a short time (less than the minimum Drain Time of 1 hour1.157407e-5 days <br />2.777778e-4 hours <br />1.653439e-6 weeks <br />3.805e-7 months <br />) from the control room following plant procedures.
2.2 Variations 2.2.1 Proposed TS Changes to Adopt TSTF-583-T, "TSTF-582 Diesel Generator Variation" TSTF-582, "RPV WIC Enhancements," states:
The ECCS injection/spray subsystem required to be operable by LCO 3.5.2 must be capable of being manually started as defense-in-depth against an unexpected draining event. The changes in TSTF-542 did not assume automatic actuation of the ECCS subsystem . TS 3.5.2, Required Action D.1 requires an additional method of water injection and that the required ECCS injection/spray subsystem or additional method of water injection shall be capable of operating without offsite electrical power. However, LCO 3.5.2 does not assume that the onsite electrical power source will start automatically on an ECCS or loss of power signal.
Page 1
ATTACHMENT 1 Description and Assessment LCO 3.8.2, "AC Sources - Shutdown ," requires one offsite circuit and one diesel generator to be operable in Modes 4 and 5. SR 3.8 .2.1 lists the TS 3.8.1, "AC Sources -
Operating," SRs that are applicable in Modes 4 and 5. In an oversight in TSTF-542 , the TS 3.8 .1 SRs that test automatic start and loading of a diesel generator on an ECCS or loss of offsite power signal were not excluded from SR 3.8.2 .1.
TSTF-582 revises Technical Specification (TS) 3.8.2, "AC Sources - Shutdown," Surveillance Requirement (SR) 3.8.2 .1, to exclude SRs that verify the ability of the diesel generators to automatically start and load on an ECCS initiation signal or loss of offsite power signal.
The NRC Safety Evaluation for TSTF-582 (ADAMS Accession No. ML20223AOOO, dated, August 13, 2020), Section 3.6, "Alternating Current Sources - Shutdown, STS 3.8.2," states:
STS 3.5.2, "Reactor Pressure Vessel Water Inventory Control (RPV WIC)," does not require automatic ECCS initiation to mitigate a draining event in Modes 4 and 5, and the ECCS initiation signal related to the automatic ECCS initiation is removed from the STS .
Because the automatic ECCS initiation and related ECCS initial signal in Modes 4 and 5 are eliminated , the automatic start of the DG on an ECCS initiation signal is not required in Modes 4 and 5 . ... [T]he NRC staff finds that STS 3.5.2 provides enough time from the onset of the [loss of offsite power] LOOP event for the operator to manually start the DG required to supply power to the water injection equipment to mitigate the draining event in Modes 4 and 5. In addition, STS 3.5.2 does not require the automatic initiation of the ECCS injection/spray subsystem or the additional method of water injection . Therefore, since STS 3.5.2 allows enough time to manually start the DG and the equipment for water injection, the NRC staff finds that the automatic start and loading of the DG are not necessary on a LOOP signal or LOOP concurrent with an ECCS initiation signal to mitigate a draining event in Modes 4 and 5.
Furthermore, the NRC staff notes that other events postulated in Modes 4 and 5 (e.g. ,
FHA, waste gas tank rupture) and during movement of [recently] irradiated fuel assemblies in the [primary and secondary containment] do not assume a LOOP event or an automatic ECCS initiation .
TSTF-582 did not include all of the TS changes needed to reflect that TS 3.8.2 should not require automatic start and loading of a diesel generator within 12 to 13 seconds (12 seconds for Clinton, and 13 seconds for Dresden, LaSalle, and Quad Cities) on an ECCS initiation signal or a loss of offsite power signal.
- TS 3.3.8.1 , "Loss of Power (LOP) Instrumentation," is applicable in Modes 1, 2, and 3, and when the associated diesel generator is required to be operable by TS 3.8.2. TSTF-582 revised TS 3.8.2 to no longer require automatic start and loading of a diesel generator on a loss of offsite power signal. Consequently, the LOP instrumentation that generates the loss of offsite power signal should not be required to be operable when the diesel generator is required to be operable by TS 3.8.2. The Applicability of LCO 3.3.8.1 is revised to not include the specified condition "When the associated diesel generator is required to be OPERABLE by LCO 3.8.2 , 'AC Sources - Shutdown'."

ATTACHMENT 1 Description and Assessment
- TS SR 3.8.1.7 and SR 3.8 .1.15 (for Clinton and LaSalle), and SR 3.8.1.8 and SR 3.8.1 .16 (for Dresden and Quad Cities), require that the DG starts from standby or hot conditions, respectively, and achieve required voltage and frequency within 12 to 13 seconds (12 seconds for Clinton , and 13 seconds for Dresden, LaSalle, and Quad Cities). The 12 to 13 second start requirement supports the assumptions in the design basis LOCA analysis.
This capability is not required during a manual diesel generator start to respond to a draining event, which has a minimum Drain Time of one hour. Therefore, SR 3.8.1.7 and SR 3.8.1 .15 (for Clinton and LaSalle), and SR 3.8.1.8 and SR 3.8.1.16 (for Dresden and Quad Cities), are added to the list of TS 3.8.1 SRs that are not applicable under SR 3.8.2.1.
These SRs are not included under SR 3.8.2.1.
- Clinton, Dresden, and Quad Cities TS SR 3.8.1.18 state "Verify interval between each sequenced load block is ~ 90% of the design interval for each load sequence time delay relay." TSTF-582 retained SR 3.8.1.18 as a test that must be met but not performed . The relay logic schemes that perform a function equivalent to a load sequencer are only used for the automatic start and loading of the diesel generator and are not used during a manual diesel generator start. Therefore, SR 3.8.1.18 is added to the list of TS 3.8.1 SRs that are not applicable under SR 3.8.2.1. This SR is not included under SR 3.8.2.1
- LaSalle TS SR 3.8 .1 .18 state "Verify interval between each sequenced load block, for Division 1 and 2 DGs only, is ~ 90% of the design interval for each load sequence time delay relay." TSTF-582 retained SR 3.8.1.18 as a test that must be met but not performed . The relay logic schemes that perform a function equivalent to a load sequencer are only used for the automatic start and loading of the diesel generator and are not used during a manual diesel generator start. Therefore, SR 3.8.1.18 is added to the list of TS 3.8.1 SRs that are not applicable under SR 3.8.2.1 . This SR is not included under SR 3.8 .2.1 The TS 3.8.2 LCO Bases were not updated by TSTF-542 or TSTF-582 to reflect that automatic start and loading of a diesel generator is not required. The LCO 3.8.2 and SR 3.8.2.1 Bases are revised to reflect the TS requirements .
This variation provides consistency within the TS after incorporating the TSTF-582 changes to SR 3.8.2 .1.
As an editorial improvement, SR 3.8.2.1 is revised to list the TS 3.8.1 SRs that are applicable instead of listing the TS 3.8 .1 SRs that are not applicable. The SR 3.8.2.1 Bases are not affected and explain why the omitted TS 3.8.1 SRs are not applicable to TS 3.8.2.

ATTACHMENT 1 Description and Assessment 2.2.2 Editorial Variations The Clinton, Dresden, LaSalle, and Quad Cities TS utilize different numbering and titles than the Standard Technical Specifications on which TSTF-582 and TSTF-583-T were based . Table 1 describes the differences between the plant-specific TS numbering and titles and the TSTF-582 and TSTF-583T numbering and titles. These differences are administrative and do not affect the applicability of TSTF-582 to these plant's TS.

EGC is proposing to delete TS 3.3 .6.1 Required Actions M.3.1, M.3.2, M.3.3, and M.3.4 . These are not included in TSTF-582. With the TSTF-582 deletion of TS 3.3.6.1 M.2 for Clinton (J.2 in TSTF-582), TS 3.3.6. 1 Required Actions M.3.1, M.3.2, M.3.3, and M.3.4 are no longer applicable. These Clinton specific actions are no longer applicable after adoption of TSTF-542 (Reference 5, 6, and 7). Required Actions M.3.1, M.3.2, M.3.3, and M.3.4 should be deleted with the deletion of TS 3.3.6.1 M.2. This plant specific variation does not impact the applicability of TSTF-582 to the Clinton TS.

3.0 REGULATORY ANALYSIS
3.1 No Significant Hazards Consideration Determination Analysis Exelon Generation Company, LLC (EGC), requests adoption of TSTF 582 , "Reactor Pressure Vessel Water Inventory Control (RPV WIC) Enhancements." The Technical Specifications (TS) related to RPV WIC are revised to incorporate operating experience and to correct errors and omissions that were incorporated into the plant TS when adopting TSTF-542 , Revision 2, "Reactor Pressure Vessel Water Inventory Control." TSTF-582 includes the following changes to the TS:
- 1. The Drain Time definition is revised to move the examples of common mode failure mechanisms to the Bases and seismic events are no longer considered a common mode failure mechanism .
- 2. The Drain Time definition exception from considering the Drain Time for penetration flow paths isolated with manual or automatic valves that are "locked, sealed, or otherwise secured" is revised to apply the exception for manual or automatic valves that are "closed and administratively controlled."
- 3. The TS are revised to permit placing an inoperable isolation channel in trip as an alternative to declaring the associated penetration flow path incapable of automatic isolation .
- 4. A Surveillance Requirement (SR) that requires operating the required Emergency Core Cooling System (ECCS) injection/spray subsystem for at least 10 minutes through the recirculation line , is modified to permit crediting normal operation of the system to satisfy the SR and to permit operation through the test return line.
- 5. Dresden, Unit 2 and 3 share secondary containment structures between units. LaSalle, Unit 1 and 2 share secondary containment structures between units. Quad Cities, Unit 1 and 2 share secondary containment structures between units. The TS Actions are revised to recognize that an operable secondary containment and operable secondary containment isolation valves satisfy the Required Actions.
- 6. The Clinton, Dresden, LaSalle , and Quad Cities designs contain additional isolation instrumentation functions based on low RPV water level that could be credited when calculating Drain Time. Those functions are added to the required functions in TS 3.3.5 .2.
- 7. TS 3.8.2, "AC Sources - Shutdown ," SR 3.8 .2.1, is revised to not require SRs that test the ability of the automatic diesel generator to start in Modes 4 and 5. Automatic ECCS Page 6
ATTACHMENT 1 Description and Assessment initiation in Modes 4 and 5 was eliminated in TSTF-542. This was an oversight in TSTF-542.
- 8. TS 3.3 .6.1, "Primary Containment Isolation Instrumentation," Required Action J.2 (J .2 for LaSalle and M.2 for Clinton) is deleted . This action is no longer applicable after adoption of TSTF-542. This was an accidental omission in TSTF-542. This change is made for clarity and has no effect on the application of the TS .
- 9. The Applicability of TS 3.6.1.3, "Primary Containment Isolation Valves (PCIVs)," is revised to delete the phrase, "When associated instrumentation is required to be OPERABLE per LCO 3.3.6.1, 'Primary Containment Isolation Instrumentation'." This makes TS 3.6.1.3 only applicable Modes 1, 2, and 3. Following adoption of TSTF-542, no functions in LCO 3.3.6 .1 are applicable outside of Modes 1, 2, or 3. The Actions and SRs are revised to reflect this change. These changes are made for clarity and have no effect on the application of the TS.
- 10. The TS are revised to use wording and to define acronyms in a manner consistent with the remainder of the TS. These changes are made for consistency and have no effect on the application of the TS.
EGC has evaluated whether or not a significant hazards consideration is involved with the proposed amendment(s) by focusing on the three standards set forth in 10 CFR 50.92, "Issuance of amendment," as discussed below:
- 1. Does the proposed change involve a significant increase in the probability or consequences of an accident previously evaluated?
Response: No The proposed change incorporates operating experience and corrects errors and omissions that were incorporated into the plant TS when adopting TSTF-542, Revision 2, "Reactor Pressure Vessel Water Inventory Control." Draining of RPV water inventory in Mode 4 (i.e., cold shutdown) and Mode 5 (i.e., refueling) is not an accident previously evaluated and , therefore , revising the existing TS controls to prevent or mitigate such an event has no effect on any accident previously evaluated. RPV water inventory control in Mode 4 or Mode 5 is not an initiator of any accident previously evaluated. The existing and revised TS controls are not mitigating actions assumed in any accident previously evaluated .
Therefore, the proposed change does not involve a significant increase in the probability or consequences of an accident previously evaluated .
Page 7
ATTACHMENT 1 Description and Assessment
- 2. Does the proposed change create the possibility of a new or different kind of accident from any previously evaluated?
Response: No The proposed change incorporates operating experience and corrects errors and omissions that were incorporated into the plant TS when adopting TSTF-542, Revision 2, "Reactor Pressure Vessel Water Inventory Control." The event of concern under the current requirements and the proposed change is an unexpected draining event. The TS have contained requirements related to an unexpected draining event during shutdown for over 40 years and this event does not appear as an analyzed event in the Updated Final Safety Analysis Report (UFSAR) for any plant or in the NRC's Standard Review Plan (NUREG- 0800). Therefore, an unexpected draining event is not a new or different kind of accident not considered in the design and licensing bases that would have been considered a design basis accident in the UFSAR had it been previously identified.
None of the equipment affected by the proposed change has a design function described in the UFSAR to mitigate an unexpected draining event in Modes 4 or 5, although the equipment may be used for that purpose. Therefore, the proposed amendment will not change the design function of the affected equipment. The proposed change will affect the operation of certain equipment, such as the manual initiation function and related instrumentation to permit initiation of the required ECCS injection/spray subsystem, and the control of valves credited for preventing a draining event. However, these changes provide adequate protection to prevent or mitigate an unexpected draining event and do not create the possibility of a new or different kind of accident due to credible new failure mechanisms, malfunctions, or accident initiators not considered in the design and licensing bases.
Therefore, the proposed change does not create the possibility of a new or different kind of accident from any previously evaluated.
- 3. Does the proposed change involve a significant reduction in a margin of safety?
Response: No The proposed change incorporates operating experience and corrects errors and omissions that were incorporated into the plant TS when adopting TSTF-542, Revision 2, "Reactor Pressure Vessel Water Inventory Control." The safety basis for the RPV WIC requirements is to protect Safety Limit 2.1.1.3. The proposed change does not affect any specific values that define a safety margin as established in the licensing basis. The proposed change does not affect a design basis or safety limit, or any controlling value for a parameter established in the UFSAR or the license.
Therefore, the proposed change does not involve a significant reduction in a margin of safety.
Page 8
ATTACHMENT 1 Description and Assessment Based on the above, EGC concludes that the proposed change presents no significant hazards consideration under the standards set forth in 10 CFR 50 .92(c), and , accordingly, a finding of "no significant hazards consideration" is justified.
3.2 Conclusions In conclusion , based on the considerations discussed above , (1) there is reasonable assurance that the health and safety of the public will not be endangered by operation in the proposed manner, (2) such activities will be conducted in compliance with the Commission's regulations, and (3) the issuance of the amendment will not be inimical to the common defense and security or to the health and safety of the public.
4.0 ENVIRONMENTAL CONSIDERATION
The proposed change would change a requirement with respect to installation or use of a facility component located within the restricted area, as defined in 10 CFR 20, or would change an inspection or surveillance requirement. However, the proposed change does not involve (i) a significant hazards consideration, (ii) a significant change in the types or significant increase in the amounts of any effluents that may be released offsite, or (iii) a significant increase in individual or cumulative occupational radiation exposure. Accordingly, the proposed change meets the eligibility criterion for categorical exclusion set forth in 10 CFR 51.22(c)(9).
Therefore, pursuant to 10 CFR 51.22(b), no environmental impact statement or environmental assessment need be prepared in connection with the proposed change.

CORE OPERATING LIMITS The COLR is the unit specific document that REPORT (COLR) provides cycle specific parameter limits for the current reload cycle . These cycle specific limits shall be determined for each re l oad cycle in accordance with Specification 5 . 6 . 5 . Plant operation within these limits is addressed in individual Specifications .
DOSE EQUIVALENT I - 131 DOSE EQUIVALENT I - 131 shall be that concentration of I - 131 (microcuries/gram) that alone would produce the same inhalation CEDE dose as the quantity and isotopic mixture of I - 131 , I - 132 ,
I - 133 , I - 134 , and I - 135 actually present . The inhalation CE DE dose conversion factors used for this calculation shall be those listed in Table 2.1 of Federal Guidance Report 11 , " Limiting Values of Radionuclide Intake and Air Concentration and Dose Conversion Factors for Inhalation , Submersion , and Ingestion ," ORNL ,
1989.
DRAIN TIME The DRAIN TIME is the time it would take for the water inventory in and above the Reactor Pressure Vessel (RPV) to drain to the top of the active fuel (TAF) seated in the RPV assuming :
- a. The water inventory above the TAF is divided by the limiting drain rate;
- b. The limiting drain rate is the larger of the drain rate through a single penetration flow path with the highest flow rate , or the sum of the drain rates through multiple penetration flow paths susceptible to a common mode failure (e g I 8ei8mic e u ent , .l.B-8-& M normal po 1er , Bingle R-Yma-n error ) , for all 1

DRAIN TIME The DRAIN TIME is the time it would take for the water inventory in and above the Reactor Pressure Vessel (RPV) to drain to the top of the active fuel (TAF) seated in the RPV assuming:
- a. The water inventory above the TAF is divided by the l imiting drain rate;
- b. The lim i ting drain rate is the larger of the drain rate through a single penetration flow path with the highest flow rate, or the sum of the dra i n rates through multiple penetration flow paths susceptible to a common mode failu re (e . g ., seismic event , loss of normal
~0 .1er , single ~u1man error) , for all 1
penet rat ion flow paths below the TAF except:
- 1. Penetration flow paths connected to an closed and administratively intact closed system, or isolated by manual or automatic valves that are controlled l ocked , sea l ed , or 0H1ernise seCblred in the closed position, blank flanges, or other devices that prevent flow of reactor coolant through the penetration flow paths;
- 2. Penetration flow paths capable of being isolated by valves that will close automatically without offsite power prior to the RPV water level being equal to the TAF when actuated by RPV water level isolation instrumentation; or (continued)

DRAIN TIME The DRAIN TIME is the time it would take for the water inventory in and above the Reactor Pressure Vessel (RPV) to drain to the top of the active fuel (TAF) seated in the RPV assuming:
- a. The water inventory above the TAF is divided by the limiting drain rate;
- b. The limiting drain rate i s the larger of the drain rate through a s ingle penetration flow path with the highest flow rate, or the sum of the drain rates through multiple penetration flow paths susceptible to a common mode failure (e . g ., seismic eveRt ,
l oss of Rormeil poi,ier , siRgle hblmeiR error) ,
for all penetration flow paths below the TAF except:
- 1. Penetration flow paths connected to an intact closed system, or i so lated by closed and administratively controlled manual or automat ic va l ves that are l ockeEi , seei l eEi , or otheni'i se secblreEi in the closed position, blank flanges, or other devices that prevent flow of reactor coolant through the penetration flow paths;
- 2. Penetration flow paths capab le of being isolated by valves that wi ll close automatically with out offsite power prior to the RPV water le vel being equal to the TAF when actuated by RPV water le ve l isolation instrumentation; or
- 3. Penetration flow paths with is olation devices that can be closed prior to the RPV water level being equal to the TAF by a dedicated operator trained in the task, who is in continuous commun ication with the control room, i s stat ioned at the controls, and is capable of closing the penetration flow path i solat ion device without offsite power.

RPV Water Inventory Control Instrumentation B 3.3.5.2 B 3.3 INSTRUMENTATION B 3.3 . 5 . 2 Reactor Pressure Vessel (RPV) Water Inventory Control Instrumentation BASES BACKGROUND The RPV contains penetrations below the top of the active fuel (TAF) that have the potential to drain the reactor coolant inventory to below the TAF. If the water level should drop below the TAF , the ability to remove decay heat is reduced , which could lead to elevated cladding temperatures and clad perforation . Safety Limit 2 . 1 . l . 3 requires the RPV water level to be above the top of t he active irradiated fuel at all times to prevent such elevated cladding temperatures .
Technical Specifications are required by 10 CFR 50 . 36 to include limiting safety system settings (LSSS) for variables that have significant safety functions . LSSS are defined by the regulation as " Where a LSSS is specified for a variable on which a safety limit has been placed , the setting must be chosen so that automatic protective actions will correct the abnormal situation before a Safety Limit (SL) is exceeded ."
The Analytical Limit is the limit of the process variab l e at which a safety action is initiated to ensure that a SL is not exceeded. Any automatic protection action that occurs on reaching the Analytical Limit therefore ensures that the SL is not exceeded . However , in practice , the actual settings for automatic protection channels must be chosen to be more conservative than the Analytical Limit to account for instrument loop uncertainties related to the set t ing at which the automatic protective action would actually occur.
The actual settings for the automatic isolation channels are the same as those established for the same functions in MODES 1 , 2 , and 3 in +/-rG.Q. ;;J ;;J 5 1 , " I!:merr;;rerH:;y GG..re. C.:wliHr;;T
£ystem (I!:CC£ ) I HstnameHtatiGH 1 " G-.:i:: LCO 3 . 3 . 6 .1, " Primary Containment Isolation instrumentation. "
With the unit in MODE 4 or 5 , RPV water inventory control is not required to mitigate any events or accidents evaluated in the safety analyses . RPV water inventory control is required in MODES 4 and 5 to protect Safety Limit 2 . 1 . 1 . 3 and the fuel cladding barrier to prevent the release of radioactive material should a draining event occur. Under the definition of DRAIN TIME , some penetration flow paths may be excluded from the DRAIN TIME calculation if they will be isolated by valves that will close automatically without offsite power prior to the RPV water level being equal to the TAF when actuated by RPV water level isolation instrumentation .

APPLICAB LE With the unit in MODE 4 or 5 , RPV water inventory co n trol is SAFETY not required to mitigate any events or accidents evaluated ANALYSES , LCO , in the safety analyses . RPV water invento r y con t rol is and APPLICAB I LI TY required in MO DE S 4 and 5 to protect Safe t y Limit 2 . 1 . l . 3 and the fuel c l adding barr i er to prevent t he release of radioactive material shou l d a draining event occur .
A double - e n ded gui l lotine break of the Reactor Coolant considered System (RCS ) is not in MODES 4 and 5 due t o the r n reduced RCS pressure , reduced p ipin stresses , and ducti l e considered piping systems . I nstead , an event is poe:tt1lat e 9 i n which a siHgle operator ~ G--T- initiating event a l lows draining of the RPV water inventory through a sing l e penetration flow path with the highest f l ow rate , or the s u m of the drain rates through mu l tiple penetration f l ow paths suscep t ible to a common mode fa i lure (e g , seismic e " eHt , +/-G-&& G..t: Horma l pm er , siHgle R-Yrn error ) . It is assumed , based on 1
engineering judgment , that while in MODES 4 and 5 , one ECCS injection/spray subsystem can b e manua l ly init i ated to maintain adequate reactor vessel water l evel .
As discuss e d in Re f e rences 1 , 2 , 3 , 4 , and 5 , ope rating experience has shown RPV water inventory to be significant to public health and safety . Therefore , RPV Water Inventory Control satisfies Criterion 4 of 10 CFR 50 . 36 (c ) (2 ) (ii ) .
Permissive and interlock setpoints are genera l l y considered as nominal values without regard to measurement accuracy .
The specific App l icable Safety Ana l yses , LCO , and Applicability discussions are listed below on a Function by Function basis .

SR 3.3.5.2.l Performance of the CHANNEL CHECK ensures that a gross failure of instrumentation has not occurred . A CHANNEL CHECK is normally a comparison of the parameter indicated on one channel to a similar parameter on other channels . It is based on the assumption that instrument channels monitoring the same parameter should read approximately the same value .
Signifi c ant deviations between the instrument channels could be an indication of excessive instrument drift in one of the channels or something even more serious . A CHANNEL CHECK guarantees that undetected outright channel failure is limited; thus , it is key to verifying the instrumentation continues to operate properly between each CHANNEL FUNCTIONAL TEST .
Agreement criteria are determined by the plant staff , based on a combination of the channel instrument uncertain t ies ,
including indication and readability . If a channel is outside the criteria , it may be an indication that the instrument has drifted outside its limit .
The Surveillance Frequency is controlled under the Surveillance Frequency Control Program.
The CHANNEL CHECK supplements less formal , but more frequent , checks of channels during normal operational use of the displays associated with the channels required by the LCO .

If the channel is not restored to OPERABLE status or placed in trip , or any Required Action of Condition I or J is not met and the associated Completion Time has expired , the plant must be placed in a MODE or other specified condition in which the LCO does not apply . This is done by placing the p l ant in at l east MODE 3 within 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br /> and in MODE 4 within 36 hours4.166667e-4 days <br />0.01 hours <br />5.952381e-5 weeks <br />1.3698e-5 months <br /> . The allowed Completion Times are reasonable , based on operating experience , to reach t he required plant conditions from full power conditions in an order l y manner and without challenging plant systems .
L . 1 and L . 2 If the channel is not restored to OPERABLE status wi t hin the allowed Completion Time , the associated SLC subsystem(s) is declared inoperable or the RWCU System is isolated . Since this Function is required to ensure that t he SLC System performs its intended function , sufficient remedial measures are provided by declaring the associated SLC subsystem inoperable or isolating the RWCU System .
The Completion Time of 1 hour1.157407e-5 days <br />2.777778e-4 hours <br />1.653439e-6 weeks <br />3.805e-7 months <br /> is acceptable because it minimizes risk while allowing sufficient time for personnel to isolate the RWCU System . RWCU isolation is achieved by closing 1G33F001 or 1G33F004 , which are the containment isolation valves associated with this isolation function .

If the channel is not restored to OPERABLE status or placed in trip within the allowed Completion Time , the associated penetration flow path should be isolated (i . e ., closing either 1El2 - F008 or 1El2 - F009) . However , if the shutdown cooling function is needed to provide core cooling , these Required Actions allow the penetration flow path to remain uniso l ated provided action is immediately initiated t o restore the channel to OPERABLE status G-F w firo u ide ffie.a+l ~ Gontrol G-f. flOtential radioaGti u e releases . ~

SYS TEM B 3.5.2 RPV Water I nventory Control BASES BACKGROUND The RPV co n tains penetrations be l ow t h e top o f the active fuel (TAF ) t h at have the potential to drain the reac t or coo l an t inventory to be l ow the TAF . If the water leve l should drop be l ow the TAF , the ability to remove decay heat is reduced , wh ich could lead to elevated cladding temperatures and c l ad perforation . Safety Limit 2 . 1 . l . 3 requires the RPV water l evel to be above the top of t he active irradiated f u el at all times to prevent such eleva t ed cladding temperatures .
APPLICAB LE With t h e unit in MODE 4 or 5 , RPV water inventory contro l is SAFETY ANALYS ES not required to mitigate any events or accidents eva l uated in the safety analyses . RPV water inventory control is required in MO DE S 4 and 5 to protect Safety Limit 2 . 1 . 1 . 3 and the fuel c l adding barrier to prevent the re l ease of radioactive material to the environment should an unexpected draining event occur .
!considered ID gg n b l e ended qui:l,lotine break of the Reactor Coolant System (RCS ) is no~ p98ttt l atgg in MODES 4 and 5 due t o the reduced RCS pressure , reduced piping stresses , and ducti l e

Instead , an event is considered in which an event that creates singlg gpgratgr m G-r- in i tiating event a l lows draining of the RPV water inventory through a sing l e penetration flow a drain path through path with the highest f l ow rate , or the sum of the drain multiple vessel rates throu h mu l ti le enetration f l ow a h suscep t ible to penetrations located a common mode fa i lure ( ~ sgismi8 g u gnt , loss of normal power , single human error ) . It is assumed , based on below top of active engin ring judgment , that while in MO DES 4 and 5 , o n e l ow fuel , such as pr e ssu e ECCS injection/spray subsyst e m can maintain adequa e reactor vessel water level .
or As discussed in References 1 , 2 , 3 , 4, and 5 , operating experience has shown RPV water inventory to be significant to public h ealth and safety . Therefore , RPV Water Inventory Control satisfies Criterion 4 of 10 CFR 50 . 36 ( c ) (2 ) (ii ).
LCO The RPV water l eve l mu st be controlled in MODES 4 and 5 to ensure that if an unexpected draining event should occur ,
the reactor coolant water level rema i ns above the top of t he active irradiated f u el as required by Safety Limit 2 . 1 . 1 . 3 .
The Limiting Condition for Operation (LCO ) requires t he DRAIN TIME of RPV water inventory to the TAF to be ~ 36 hours4.166667e-4 days <br />0.01 hours <br />5.952381e-5 weeks <br />1.3698e-5 months <br />.

Management o f gas voids is from the control room. important to ECCS injection/spray subsystem OPERABI LITY .
The LCO is modif i ed by a Note t h at al l ows a LPCI subsystem to be inoperab l e during a l ignment and operation for decay heat removal with reactor steam dome pressure less than t h e residual heat removal cut - i n permissive pressure. Th is is necessary since the RHR system is requ ired to operate in the shutdown coo l ing mode to remove decay heat and sensible hea t from the reactor , and manual realignment from the shutdown coo li ng mode to t h e LPC I mode cou l d r esu l t i n p ump cavitation and voiding in the suction piping , resulting in the potentia l to damage the RHR system , inc l uding wa t er hammer . One LPC I s u bsystem is a l lowed to be considered inoperable for this tempora r y p eriod , because in s h u t down cooling mode it i s fu l fil l i ng a decay heat remova l capaci t y f u nction . At these low pressures and decay h eat levels , a reduced comp l e ment of ECCS s u bsystems should provide the required core cooling , thereb y a l low i ng operation of RHR shutdown coo l ing when necessary . Becau se of the restrictions on DRAIN TI ME , sufficient time wil l be available fo l low i ng an unexpected dra i ning even t to manua l ly align and operate t h e re q uired LPCI subsystem to mai n tain RPV wa t er inventory prior t o the RPV water l eve l reach ing the TAF .

For a Control Rod RPV penetration flow path with the Control Rod Drive Mechanism removed and not replaced with a blan k flange , the realistic cross - sectional area is based on the control rod blade seated in the control rod guide tube. If the control rod blade will be raised from the penetration to adjust or verify seating of the blade , the exposed cross -

ITY I t is acceptab l e for divis i ons to be cross t i ed during shutdown conditions , permitting a s i ng l e offsite power circuit to supply all required AC e l ectrica l power distribution subsystems . No fast transfer capabi l ity is required for o ff site circuits to be considered OPERABLE for this LCO .
As described in Applicable Safety Analyses , in the event of an accident during shutdown , the TS are designed to maintain the p l ant in a condition s u ch that, e¥ef+ :w-i-t-A, ~ siAgle faili;ire , the p l ant will not be in immediate difficulty .
APPLICABILITY The AC sources required to be OPERABLE in MODES 4 and 5 and during movement of irradiated fuel assemblies i n the primary or secondary containment provide assurance that :
- a. Systems that provide core cooling are ava i lable ;
- b. Systems needed to mitigate a fuel handling accident are availab l e ;

SURVEILLANCE SR 3.8.2.1 REQUIREMENTS SR 3 . 8 . 2 . 1 requires the SRs from LCO 3 . 8 . 1 that are necessary for ensuring the OPERABILITY of the AC sources in SR 3.8 .1.7, SR o t her tha ~MODES 1 , 2 , and 3 . SR 3 . 8.1 . 8 is not requ ired to 3.8.1.11, SR 3.8.1.12, be met sin e only one offsite circuit is required to be SR 3.8.1.13, SR OPERABLE . In MODES 4 and 5 ECCS injection/spray subsystems 3.8 .1.15, SR 3.8 .1.18, are manually controlled in accordance with LCO 3 . 5 . 2 ,
" Reactor Pressure Vesse l (RPV) Water I nventory Contro l." No and SR 3.8.1 .19 are ECCS initiation signals are credited for initiation of these not required to be met subsystems . Adequate time is availab l e to manually start because DG start and and load DGs from the Main Contro l Room in support of RPV load within a specified inventory contro l, if required . Therefore , SR 3 . 8 . 1 . 12 and SR 3 . 8 . 1 . 19 , which verify the DG ' s capability to start time and response on automatically on actual or simulated ECCS init i ation an offsite power or signa l s , are not required to be met i n MODES 4 and 5 .
ECCS initiation signal SR 3 . 8 . 1 . 17 is not required to be met because the required is not required. OPERABLE DG (s ) is not required to undergo periods of being synchronized to the offsite circuit . SR 3 . 8 . 1.20 is excepted because starting i ndependence is not required with the DG ( s ) that is not required to be OPERABLE . Refer to the corresponding Bases for LCO 3 . 8 . 1 for a discussion of each lwhich precludes <;: P' This SR is modified by a Note~~ ~ reasgn

paral l eled with the offsite power network or otherwise rendered inoperable during the performance of SRs , and preclude de - energizing a required 4 .1 6 kV ESF bus or disconnecting a requ ired offsite circuit during performance of SRs . With l imited AC sources available , a single event could compromise both the required circuit and the DG . It is the intent that these SRs must sti l l be capable of being met , but actua l performance is not required for any DG or offsite circuit .
