ATTACHMENT 1 Response to Request for Additional Information

===Background===
Paragraph 50.36(c)(3) of Title 10 of the Code of Federal Regulations (10 CFR) requires that TSs include surveillance requirements (SRs), which are requirements relating to test, calibration, or inspection to assure that the necessary quality of systems and components is maintained, that facility operation will be within safety limits, and that the limiting conditions for operation (LCOs) will be met.
The LCO and associated SRs for alternating-current (AC) electrical power sources that are applicable when a unit is in modes 1, 2, and 3 are specified in TS 3.8.1, "AC Sources -
Operating." The LCOs and associated SRs for AC electrical power sources and electrical distributions systems that are applicable when a unit is in modes 4 and 5 or during movement of recently irradiated fuel assemblies in the secondary containment are specified in TS 3.8.2, "AC Sources - Shutdown," and TS 3.8.8, "Distribution Systems - Shutdown," respectively.
Request Additional Information {RAI) 1 {Dresden)
Section 8.3.1.5.2 , "System Arrangement," of the Dresden Updated Final Safety Analysis Report (UFSAR) states, in part, that diesel generator (DG) 2 provides power to the Division II emergency core cooling system (ECCS) equipment for Unit 2, and DG 3 provides power to Division II ECCS equipment for Unit 3. DG 2/3 provides power to the Division I ECCS equipment for either Unit 2 or Unit 3.
Dresden LCO 3.8.1.d requires that the following AC electrical power source be operable when the unit is operating : "The opposite unit's DG capable of supporting the equipment required to be OPERABLE by LCO 3.6.4.3, LCO 3.7.4 (Unit 3 only), and LCO 3.7.5 (Unit 3 only)." SR 3.8.1.21 is applicable to the opposite unit's AC electrical power sources and it specifies, in part, the SRs necessary to meet LCO 3.8.1.d.
Dresden LCO 3.8.2.b requires that the following AC electrical power source be operable when the unit is shutdown: "One diesel generator (DG) capable of supplying one division of the onsite Class 1E AC electrical power distribution subsystem(s) required by LCO 3.8.8." When a unit is shutdown, Dresden LCO 3.8.8 requires: "The necessary portions of the AC , DC [direct current],
and the opposite unit's Division 2 electrical power distribution subsystems shall be OPERABLE to support equipment required to be OPERABLE." Dresden SR 3.8.2.1 specifies the SRs in TS 3.8.1 that are necessary to meet LCO 3.8.2.
The licensee proposed to revise Dresden SR 3.8.2.1 as shown in the table below. The proposed changes would make several SRs for AC sources required by TS 3.8.2 no longer applicable . The licensee also proposed to revise TS 3.3.8.1, "Loss of Power (LOP)
Instrumentation," such that LCO 3.3.8.1 would no longer be applicable "[w]hen the associated diesel generator is requ ired to be OPERABLE by LCO 3.8.2, 'AC Sources Shutdown."' The LAR states that these changes are based on TSTF-582 and TSTF-583-T. However, these travelers and the NRC safety evaluation for TSTF-582 do not address shared AC sources at multi-unit sites. In addition , the LAR does not address the shared AC sources at Dresden . The LAR also proposes, without justification, to delete SRs currently required by SR 3.8.2.1 (e.g.,
Dresden SR 3.8.1. 7) which are not included in the TSTF-582 or TSTF-583-T changes . The proposed changes would also make SR 3.8.2.1 inconsistent with SR 3.8.1.21 .

ATTACHMENT 1 Response to Request for Additional Information Response to RAI 1 (Dresden):
Part A Dresden Surveillance Requirement (SR) 3.8.2.1 lists the subset of SRs from Technical Specification (TS) 3.8.1, "AC Sources - Operating," that are required to be met for alternating current (AC) electrical power sources that are required to be operable by limiting condition for operation (LCO) 3.8.2, "AC Sources - Shutdown." LCO 3.8.2 is applicable to a unit that is in modes 4 or 5, or during movement of recently irradiated fuel assemblies in the secondary containment. LCO 3.8.2 requires one offsite circuit between the offsite transmission network and the onsite Class 1E AC electrical power distribution subsystem(s) required by LCO 3.8.8, "Distribution Systems - Shutdown," and one diesel generator (DG) capable of supplying one division of the onsite Class 1E AC electrical power distribution subsystem(s) required by LCO 3.8.8.
According to LCO 3.0.9 and SR 3.0.5, LCOs and SRs, respectively, are applied individually to each unit at a dual-unit site, such that the operating mode of one unit does not affect the application of the TS to the opposite unit. Therefore, the TS 3.8.1 SRs that are currently required to be met by SR 3.8.2.1 when a unit is in the mode of applicability of SR 3.8.2 are independent of the opposite unit's mode. The applicability of these SRs under the current Dresden SR 3.8.2.1 wording (prior to adoption of TSTF-582) is summarized in Table 1A-1 .

          **For Unit 3, the required DG will be either the Unit 3 DG or the Unit 2/3 (shared) DG.
LCOs 3.6.4 .3, 3.7.4, and 3.7.5 are not applicable to a unit that is in mode 4 or 5 unless recently irradiated fuel is being moved in the shared secondary containment. These LCO's, when applicable, require equipment to be operable that is powered by both the same unit and the opposite unit's AC distribution subsystem(s). For equipment powered by the same unit (e.g., for Unit 2, 2/38 Standby Gas Treatment (SBGT), Control Room Emergency Ventilation (CREV),
and Control Room Emergency Ventilation Air Conditioning (CREV-AC)), the AC Sources required by LCO 3.8.2 support the associated equipment, with applicable SRs specified in the table above. For equipment powered by the opposite unit (e.g., for Unit 2, 2/3A SBGT), the required opposite unit distribution subsystems are required to be operable by LCO 3.8.8; however, no corresponding opposite unit requirement exists under LCO 3.8.2 for AC Sources.
This is supported by the current bases of LCO 3.8.2 state that:
         "In general, when the unit is shutdown the Technical Specification requirements ensure that the unit has the capability to mitigate the consequences of postulated accidents. However, assuming a single failure and concurrent loss of all offsite or loss of all onsite power is not required. The rationale for this is based on the fact that many Design Basis Accidents (DBAs) that are analyzed in modes 1, 2, and 3 have no specific analyses in modes 4 and 5. Worst case bounding events are deemed not credible in modes 4 and 5 because the energy contained within the reactor pressure boundary, reactor coolant temperature and pressure, and corresponding stresses result in the probabilities of occurrences significantly reduced or eliminated, and minimal consequences. These deviations from OBA analysis assumptions and design requirements during shutdown conditions are allowed by the LCO for required systems."
Therefore, under current Dresden's TS the applicable SR's of LCO 3.8.1 that are specified to be met under SR 3.8.2 .1 for the AC sources required to be operable by LCO 3.8.2 are those listed in the table above, even if movement of recently irradiated fuel in secondary containment is causing the shutdown unit to be in the mode of applicability of LCOs 3.6.4.3, 3.7.4, and 3.7.5. Adequate power to support the operability of required opposite unit equipment is assured by LCO 3.8.8.
For any operating unit, even if the opposite unit is shutdown , all SR's of LCO 3.8.1 apply to the AC sources required to be operable, which will include one qualified circuit between the offsite transmission network and the opposite unit's onsite Class 1E AC Electrical Power Distribution System and the opposite unit DG capable of supporting LCOs 3.6.4.3, 3.7.4, and 3.7.5.
Page4

ATTACHMENT 1 Response to Request for Additional Information Part B Since no changes have been proposed for SR 3.8.1.21, any opposite unit AC sources required by a unit operating in mode 1, 2, or 3 will continue to be subject to the existing set of SRs to establish operability. For multi-unit sites with shared AC distribution systems and sources, the same AC Source (e.g., a unit or shared DG) may be required for each Unit by different LCOs (e.g., LCO 3.8.1 or LCO 3.8.2); however, the basis for the equipment being required to be operable is different for an operating unit versus a shutdown unit. Since the operating unit must still have the capability to mitigate the effects of Design Basis Accidents (OBA) analyzed for operating conditions (e.g., OBA Loss of Coolant Accident), all of the requirements associated with DG automatic start in response to Emergency Core Cooling Systems (ECCS) or Loss of Offsite Power (LOOP) signals, time to achieve rated voltage and frequency, and load sequencing continue to be required. Thus, no changes to SR 3.8.1.21 are appropriate or proposed.
As described in the Safety Evaluation for TSTF-582 (Reference 1) and supported by the Loss of Power (LOP) Variation model Safety Evaluation (Reference 2), the DGs supporting a shutdown unit (operating in mode 4, 5, or during movement of recently irradiated fuel in secondary containment) may be manually started and loaded in response to a Reactor Pressure Vessel (RPV) draining event. Furthermore, the essential consideration for the events assessed in Reference 1, namely that the Fuel Handling Accident (FHA) does not assume a LOOP and that the minimum Drain Time permitted for any duration by LCO 3.5.2 is 1 hour, are consistent with the Dresden licensing basis. The ability of each required DG to support the required loads via manual start and loading continues to be demonstrated by the SRs that are retained under the proposed revision to SR 3.8.2.1. Additionally, for the FHA, no credit in the analysis is taken for the operation of SBGT, GREV, or GREV-AC (Reference 3). Equipment required by LCOs 3.6.4.3, 3.7.4, and 3.7.5 will continue to be supported by operable distribution subsystems specified by LCO 3.8.8. The Dresden licensing basis does not include any additional events requiring automatic start of DGs for a shutdown unit that have not already been considered in the safety evaluation for TSTF-582 (i.e. , Fuel Handling Accident, draining event in mode 4 or 5).
The proposed LAR does not affect which AC sources will be required via LCO 3.8.2 to support the distribution systems required operable via LCO 3.8.8, but only revises the applicable SRs that are required to consider a DG operable for LCO 3.8.2 (though additional SRs may apply to the same DG and its associated start logic if required by an operating unit via SR 3.8.1.21 ).
Based on the above considerations, justification for deletion of each proposed SR of LCO 3.8.1 from the list of SRs required by the DG(s) required to be operable by LCO 3.8 .2 is provided :
SR 3.8.1 .8 This surveillance verifies the DG ability to achieve required voltage and frequency within 13 seconds. The 13 second timeframe is not required to support manual start of the DG in response to the postulated events in mode 4 or 5, and the ability of the DG to be manually started and loaded continues to be demonstrated by SR 3.8.1.2. If an operating unit requires the same DG to be operable, this surveillance will continue to be applicable for the operating unit via SR 3.8.1.21 . This SR is equivalent to SR 3.8.1.7 from NUREG-1433 Revision 4, with the exception that the Dresden SR includes a note allowing the performance of this test for the common DG to satisfy this SR for both Units. This SR is assessed for deletion from the NUREG-1433 Standard Technical Specification (STS) SR 3.8.2.1 in Reference 2.
Page 5

ATTACHMENT 1 Response to Request for Additional Information SR 3.8.1 .12 This surveillance verifies, in part, the automatic start and loading of a DG on a LOOP signal. As previously discussed, response to the postulated events in mode 4 and 5 does not require automatic start and loading of a DG. If an operating unit requires the same DG to be operable, this surveillance will continue to be applicable for the operating unit via SR 3.8.1.21 . This SR is equivalent to SR 3.8.1 .11 from NUREG-1433 Revision 4, with the exception that Dresden does not include the verification of auto-connected loads through a load sequencer (since the Dresden design does not have this feature). This SR is approved for deletion from the NUREG-1433 STS SR 3.8.2.1 in Reference 1.
SR 3.8.1 .14 This surveillance verifies that the required DG's noncritical automatic trips are bypassed on an actual or simulated loss of voltage signal on the emergency bus concurrent with an actual or simulated ECCS initiation signal. Since the requirement for operable ECCS initiation signals is proposed for removal from LCO 3.3.5.2, removal of this surveillance from the list of those surveillances required for a DG supporting LCO 3.8.2 establishes consistency. Consistent with the assessment provided in Section 3.6 of Reference 1, LCO 3.8.2 and LCO 3.5.2 will, upon an actual LOOP, continue to require the restoration of an RPV injection source capable of operating without offsite power within a timeframe adequate for responding to a vessel draining event. If an operating unit requires the same DG to be operable, this surveillance will continue to be applicable for the operating unit via SR 3.8.1.21. This SR is equivalent to SR 3.8.1.13 from NUREG-1433 Revision 4. This SR is approved for deletion from the NUREG-1433 STS SR 3.8.2.1 in Reference 1.
SR 3.8.1 .16 This surveillance demonstrates that the DG can restart from a hot condition, such as subsequent to shutdown from normal surveillances, and achieve the required voltage and frequency within 13 seconds. The 13 second timeframe is not required to support manual start of the DG in response to the postulated events in mode 4 or 5, and the ability of the DG to be manually started and loaded continues to be demonstrated by SR 3.8.1.2 . If an operating unit requires the same DG to be operable, this surveillance will continue to be applicable for the operating unit via SR 3.8.1 .21. This SR is equivalent to SR 3.8.1 .15 from NUREG-1433 Revision 4, with the exception that the Dresden SR includes a note allowing the performance of this test for the common DG to satisfy this SR for both Units. This SR is assessed for deletion from the NUREG-1433 STS SR 3.8.2 .1 in Reference 2.
SR 3.8.1.18 This surveillance verifies the interval between each sequenced load block is ~90% of the design interval for each load sequence time delay relay. This logic is associated with automatic start and loading of an EOG in response to an ECCS initiation signal concurrent with a LOOP. Since the requirement for operable ECCS initiation signals is proposed for removal from LCO 3.3.5.2, removal of this surveillance from the list of those surveillances required a DG supporting LCO 3.8.2 establishes consistency. Manual loading of the DG will continue to be able to be performed by licensed operators in response to the postulated events in mode 4 and 5 or during Page 6

ATTACHMENT 1 Response to Request for Additional Information movement of recently irradiated fuel in secondary containment. This SR is equivalent to SR 3.8.1 .18 from NUREG-1433 Revision 4. This SR is assessed for deletion from the NUREG-1433 STS SR 3.8.2.1 in Reference 2.
SR 3.8.1 .7 SR 3.8.1 .7 was inadvertently removed from the list of SRs required to be performed under SR 3.8.2.1 even though it is required as shown in Table 1A-1. Attachment 2 provides the corrected markup of SR 3.8.2.1. Attachment 2 will replace in its entirety Attachment 2.2 of the original submittal. However, the only change to the markup is the correction to SR 3.8.2.1 on Page 3.8.2-3.
Part C As discussed in the responses to Parts A and B, no changes are required for SR 3.8.1.21, as this SR continues to specify the appropriate criteria for operability of an opposite unit AC source that is required by a unit operating in modes 1, 2, or 3.
Part D As described in Part B, the DGs supporting a shutdown unit (operating in mode 4, 5, or during movement of recently irradiated fuel in secondary containment) may be manually started and loaded in response to a Reactor Pressure Vessel (RPV) draining event.
TSTF-582 did not include all the TS changes needed to reflect that TS 3.8.2 does not require automatic start and loading of a DG within 13 seconds on an ECCS initiation signal or LOOP signal. TSTF-583-T addressed these additional changes, which included the revision of the Applicability of LCO 3.3.8.1 to remove the currently specified condition "When the associated diesel generator as required to be OPERABLE by LCO 3.8.2 , 'AC Sources - Shutdown ."'
TS 3.3.8.1, "Loss of Power (LOP) Instrumentation," is currently applicable in modes 1, 2, and 3, and when the associated DG is required to be operable by TS 3.8.2. Implementation of TSTF-582 revises TS 3.8.2 to no longer require automatic start and loading of a DG on a LOOP signal. Consequently, the instrumentation that generates the LOOP signal should not be required to be operable when the DG is required to be operable by TS 3.8.2. As a result, the deletion of the condition related to TS 3.8.2 in the applicability of LCO 3.3.8.1 is appropriate.

Section 8.3.1.1.2, "Unit Class 1E A-C Power System ," of the LaSalle UFSAR states, in part, that the main components of the unit Class 1E AC power system for Unit 1 (or Unit 2) are three DGs, one of which is common to Unit 1 and Unit 2.
LaSalle LCO 3.8.1 .c requires that the following AC electrical power source be operable when the unit is operating : "The opposite unit's Division 2 DG capable of supporting the associated equ ipment requi red to be OPERABLE by LCO 3.6.4.3, 'Standby Gas Treatment (SGT) System ,'
LCO 3.7.4 , 'Control Room Area Filtration (CRAF) System,' and LCO 3.7.5, 'Control Room Area Ventilation Air Conditioning (AC) System."' SR 3.8.1 .21 is applicable to the opposite unit's AC electrical power sources and it specifies, in part, the SRs necessary to meet LCO 3.8.1 .c.
LaSalle LCO 3.8.2 requ ires , in part, that the following AC electrical power sources be operable when the unit is shutdown:
: b. One diesel generator (DG) capable of supplying one division of the Division 1 or 2 onsite Class 1E AC electrical power distribution subsystem(s) required by LCO 3.8.8;
: d. One qualified circuit, which may be the same circuit in LCO 3.8.2.a. between the offsite transmission network and the opposite unit Division 2 onsite Class 1E AC electrical power distribution subsystem , or the opposite unit DG capable of supplying the opposite unit Division 2 onsite Class 1E AC electrical power distribution subsystem , when the opposite unit Division 2 onsite Class 1E AC electrical power distribution subsystem is requ ired by LCO 3.8.8.
When a unit is shutdown , LaSalle LCO 3.8.8 requires: "The necessary portions of the Division 1, Division 2, and Division 3 AC and DC, and the opposite unit Division 2 AC and DC electrical power distribution subsystems shall be OPERABLE to support equ ipment required to be OPERABLE." LaSalle SR 3.8.2 .1 specifies the SRs in TS 3.8.1 that are necessary to meet LCO 3.8 .2.
The licensee proposed to revise LaSalle SR 3.8.2 .1 as shown in the table below. The proposed changes would make several SRs for AC sources required by TS 3.8.2 no longer applicable.
The licensee also proposed to revise LaSalle TS 3.3.8.1, "Loss of Power (LOP)
Instrumentation," such that LCO 3.3.8.1 would no longer be applicable "[w]hen the associated diesel generator (DG) is required to be OPERABLE by LCO 3.8.2, 'AC Sources Shutdown. "'
The LAR states that these changes are based on TSTF-582 and TSTF-583-T. However, these travelers and the NRC safety evaluation for TSTF-582 do not address shared AC sources at multi-unit sites. In addition , the LAR does not address the shared AC sources at LaSalle. The LAR also proposes, without justification , to delete SRs currently required by SR 3.8.2.1 (e.g. ,
LaSalle SR 3.8.1 .21) which are not included in the TSTF-582 or TSTF-583-T changes. The proposed changes would also make SR 3.8.2.1 inconsistent with SR 3.8.1.21 .

PART A:
LaSalle SR 3.8.2.1 lists the subset of SRs from TS 3.8.1, "AC Sources - Operating," that are required to be met for alternating current (AC) electrical power sources that are required to be operable by LCO 3.8.2, "AC Source - Shutdown." LCO 3.8.2 is applicable to a unit that is in modes 4 or 5, or during movement of irradiated fuel assemblies in the secondary containment.
LCO 3.8.2 requires one offsite circuit between the offsite transmission network and the onsite Class 1E AC electrical power distribution subsystem(s) required by LCO 3.8.8, "Distribution Systems - Shutdown," and one diesel generator (DG) capable of supplying one division of the onsite Class 1E AC electrical power distribution subsystem(s) required by LCO 3.8.8 and LCO 3.8 .2.d.
According to LCO 3.0.9 and SR 3.0.5, LCOs and SRs, respectively, are applied individually to each unit at a dual-unit site, the operating mode of one unit does not affect the application of the TS to the opposite unit. Therefore, the TS 3.8.1 SRs that are required to be met by SR 3.8.2.1 when a unit is in the mode of applicability of SR 3.8.2 are independent of the opposite unit's mode. The applicability of these SRs under the current LaSalle SR 3.8.2 .1 wording (prior to adoption of TSTF-582) is summarized in Table 2A-1.

These LCO's, when applicable, require equipment to be operable that is powered by both the same unit and the opposite unit's Division 2 AC distribution subsystem(s). For equipment powered by the same unit (e.g. , for Unit 1, Unit 1 Standby Gas Treatment (SBGT), A Control Room Area Filtration (GRAF) System, and A Control Room Area Ventilation Air Conditioning (AC) System), the AC Sources required by LCO 3.8.2 support the associated equipment, with applicable SRs specified in the table above. For equipment powered by the opposite unit (e.g., for Unit 1, Unit 2 SBGT, B Control Room Area Filtration (CRAF) System, and B Control Room Area Ventilation Air Conditioning (AC) System), the required opposite unit distribution subsystems are required to be operable by LCO 3.8.8; however, no corresponding opposite unit requirement exists under LCO 3.8.2 for AC Sources. This is supported by the current bases of LCO 3.8.2 state that:
         "In general, when the unit is shutdown the Technical Specification requirements ensure that the unit has the capability to mitigate the consequences of postulated accidents.
However, assuming a single failure and concurrent loss of all offsite or loss of all onsite power is not required . The rationale for this is based on the fact that many Design Basis Accidents (DBAs) that are analyzed in modes 1, 2, and 3 have no specific analyses in modes 4 and 5. Worst case bounding events are deemed not credible in modes 4 and 5 because the energy contained within the reactor pressure boundary, reactor coolant temperature and pressure, and corresponding stresses result in the probabilities of occurrences significantly reduced or eliminated, and minimal consequences. These deviations from OBA analysis assumptions and design requirements during shutdown conditions are allowed by the LCO for required systems."
Therefore, under current LaSalle TS the applicable SR's of LCO 3.8.1 that are specified to be met under SR 3.8.2.1 for the AC sources required to be operable by LCO 3.8.2 are those listed in the table above, even if movement of irradiated fuel in secondary containment or during core alterations are causing the shutdown unit to be in the mode of applicability of LCOs 3.6.4 .3, 3.7.4, and 3.7.5. Adequate power to support the operability of required opposite unit equipment is assured by LCO 3.8.8.
For any operating unit, even if the opposite unit is shutdown , all SR's of LCO 3.8.1 apply to the AC sources required to be operable, which will include two qualified circu its between the offsite transmission network and onsite Class 1E AC Electrical Power Distribution System, three DGs (Division 1, 2 &3), and the opposite unit's onsite Class 1E AC Electrical Power Distribution System and the opposite unit DG capable of supporting LCOs 3.6.4.3, 3.7.4, and 3.7.5.

ATTACHMENT 1 Response to Request for Additional Information PART B:
Since no changes have been proposed for SR 3.8.1.21, any opposite unit AC sources required by a unit operating in mode 1, 2, or 3 will continue to be subject to the existing set of SRs to establish operability. For multi-unit sites with shared AC distribution systems and sources, the same AC Source (e.g. , a unit or shared DG) may be required for each Unit by different LCOs (e.g. , LCO 3.8.1 or LCO 3.8.2); however, the basis for the equipment being required to be operable is different for an operating unit versus a shutdown unit. Since the operating unit must still have the capability to mitigate the effects of Design Basis Accidents (OBA) analyzed for operating conditions (e.g. OBA Loss of Coolant Accident), all of the requirements associated with DG automatic start in response to ECCS or LOOP signals, time to achieve rated voltage and frequency, and load sequencing continue to be required. Thus, no changes to SR 3.8.1.21 are appropriate or proposed.
As described in the Safety Evaluation for TSTF-582 (Reference 1) and supported by the LOP Variation model Safety Evaluation (Reference 2), the DGs supporting a shutdown unit (operating in mode 4, 5, or during movement of irradiated fuel in secondary containment) may be manually started and loaded in response to a Reactor Pressure Vessel (RPV) draining event.
Furthermore, the essential consideration for the events assessed in Reference 1, namely that the FHA does not assume a LOOP and that the minimum Drain Time permitted for any duration by LCO 3.5.2 is 1 hour, are consistent with the LaSalle licensing basis. The ability of each required DG to support the required loads via manual start and loading continues to be demonstrated by the SRs that are retained under the proposed revision to SR 3.8.2.1.
Additionally, the FHA analysis does not assume a Loss of Off-Site Power as an initial condition.
Equipment required by LCOs 3.6.4.3, 3.7.4, and 3.7.5 will continue to be supported by operable distribution subsystems specified by LCO 3.8.8. The LaSalle licensing basis does not include any additional events requiring automatic start of DGs for a shutdown unit that have not already been considered in the safety evaluation for TSTF-582 (i.e., Fuel Handling Accident, draining event in mode 4 or 5). The proposed LAR does not affect which AC sources will be required via LCO 3.8.2 to support the distribution systems required operable via LCO 3.8.8, but only revises the applicable SRs that are required to consider a DG operable for LCO 3.8.2 (though additional SRs may apply to the same DG and its associated start logic if required by an operating unit via SR 3.8.1 .21 ).
Based on the above considerations, justification for deletion of each proposed SR of LCO 3.8.1 from the list of SRs required by the DG(s) required to be operable by LCO 3.8.2 is provided:
SR 3.8.1.7 This SR requires that the DG starts from standby conditions and achieves required voltage and frequency within 13 seconds. The 13 second start requirement supports the assumptions in the design basis Loss of Coolant Accident (LOCA) analysis.
LCO 3.5.2 This LCO does not assume that the onsite electrical power source will start automatically on an ECCS or loss of power signal. Therefore, the 13 second start requirement per SR 3.8.1. 7 is not applicable.
Page 12

ATTACHMENT 1 Response to Request for Additional Information LCO 3.6.4.3, LCO 3.7.4, and LCO 3.7.5 These LCOs are only required in modes 1, 2, 3, during movement of irradiated fuel assemblies in the secondary containment and during core alterations. TS 3.8.2 does not apply in modes 1, 2 or 3. The FHA analysis does not assume a Loss of Off-Site Power as an initial condition.
LCO 3.8.8 The distribution systems required to be operable per LCO 3.8.8 are not changed by the proposed LAR. The proposed changes only revise the applicable SRs that are required to consider a DG operable per LCO 3.8.2 SR 3.8.1 .11 This SR demonstrates the as designed operation of the standby power sources during loss of the offsite source. This test verifies all actions encountered from the loss of offsite power, including shedding of the nonessential loads (Divisions 1 and 2 only) and energization of the emergency buses and respective loads from the DG. It further demonstrates the capability of the DG to automatically achieve the required voltage and frequency within the specified time .
The DG auto-start and energization of permanently connected loads time of 13 seconds is derived from requirements of the accident analysis for responding to a design basis large break LOCA.
LCO 3.5.2 This LCO does not assume that the onsite electrical power source will start automatically on an ECCS or loss of power signal. Therefore, the automatic Loss of Power diesel start per SR 3.8.1.11 is not applicable.
LCO 3.6.4 .3, LCO 3.7.4, and LCO 3.7.5 These LCOs are only required in modes 1, 2, 3, during movement of irradiated fuel assemblies in the secondary containment, and during core alterations. TS 3.8.2 does not apply in modes 1, 2 or 3. The FHA analysis does not assume a Loss of Off-Site Power as an initial condition.
LCO 3.8.8 The distribution systems required to be operable per LCO 3.8.8 are not changed by the proposed LAR. The proposed changes only revise the applicable SRs that are required to consider a DG operable per LCO 3.8.2 SR 3.8.1.12 This SR demonstrates that the DG automatically starts and achieves the required voltage and frequency within the specified time (13 seconds) from the design basis actuation signal (LOCA signal).
Page 13

ATTACHMENT 1 Response to Request for Additional Information LCO 3.5.2 This LCO does not assume that the onsite electrical power source will start automatically on an ECCS or loss of power signal. Therefore, the automatic LOCA Signal diesel start per SR 3.8.1 .12 is not applicable.
LCO 3.6.4 .3, LCO 3.7.4 , and LCO 3.7.5 These LCOs are only required in modes 1, 2, 3, during movement of irradiated fuel assemblies in the secondary containment, and during core alterations. TS 3.8.2 does not apply in modes 1, 2 or 3. The FHA analysis does not assume a Loss of Off-Site Power as an initial condition.
LCO 3.8.8 The distribution systems required to be operable per LCO 3.8.8 are not changed by the proposed LAR. The proposed changes only revise the applicable SRs that are required to consider a DG operable per LCO 3.8.2 SR 3.8.1 .13 This SR demonstrates that DG non-critical protective functions (e.g., high jacket water temperature) are bypassed on a loss of voltage signal concurrent with an ECCS initiation test signal and critical protective functions (engine overspeed and generator differential current) trip the DG to avert substantial damage to the DG unit. The non-critical trips are bypassed during DBAs and provide an alarm on an abnormal engine condition . This alarm provides the operator with sufficient time to react appropriately. The DG availability to mitigate the OBA is more critical than protecting the engine against minor problems that are not immediately detrimental to emergency operation of the DG.
LCO 3.5.2 This LCO does not assume that the onsite electrical power source will start automatically on a loss of voltage signal concurrent with an ECCS initiation signal. Therefore, SR 3.8.1.13 is not applicable.
LCO 3.6.4 .3, LCO 3.7.4, and LCO 3.7.5 These LCOs are only required in modes 1, 2, 3, during movement of irradiated fuel assemblies in the secondary containment, and during core alterations. TS 3.8.2 does not apply in modes 1, 2 or 3. The FHA analysis does not assume a Loss of Off-Site Power as an initial condition.
LCO 3.8.8 The distribution systems required to be operable per LCO 3.8.8 are not changed by the proposed LAR. The proposed changes only revise the applicable SRs that are required to consider a DG operable per LCO 3.8.2 Page 14

ATTACHMENT 1 Response to Request for Additional Information SR 3.8.1.15 This SR demonstrates that the DG can restart from a hot condition , such as subsequent to shutdown from normal surveillances, and achieve the required voltage and frequency within 13 seconds. The 13 second time is derived from the requirements of the accident analysis for responding to a design basis large break LOCA.
LCO 3.5.2 This LCO does not assume that the onsite electrical power source will start or restart following a shutdown within 13 seconds. Therefore, the diesel restart demonstration per SR 3.8.1.15 is not applicable.
LCO 3.6.4 .3, LCO 3.7.4 , and LCO 3.7.5 These LCOs are only required in modes 1, 2, 3, during movement of irradiated fuel assemblies in the secondary containment, and during core alterations. TS 3.8.2 does not apply in modes 1,2 or 3. The FHA analysis does not assume a Loss of Off-Site Power as an initial condition .
LCO 3.8.8 The distribution systems required to be operable per LCO 3.8.8 are not changed by the proposed LAR. The proposed changes only revise the applicable SRs that are required to consider a DG operable per LCO 3.8.2 SR 3.8.1.18 This SR verifies the interval between each sequenced load block is ~90% of the design interval for each load sequence time delay relay. This logic is associated with automatic start and loading of an EOG in response to an ECCS initiation signal concurrent with a LOOP. Since the requirement for operable ECCS initiation signals is proposed for removal from LCO 3.3.5.2, removal of this surveillance from the list of those surveillances required a DG supporting LCO 3.8.2 establishes consistency.
LCO 3.5.2 This LCO does not assume that the onsite electrical power source will start automatically on a loss of power signal concurrent with an ECCS initiation signal. Therefore , demonstrating the interval for each load sequence time delay relay per SR 3.8.1.18 is not applicable.
LCO 3.6.4.3, LCO 3.7.4 , and LCO 3.7.5 These LCOs are only required in modes 1, 2, 3, during movement of irradiated fuel assemblies in the secondary containment, and during core alterations. TS 3.8.2 does not apply in modes 1, 2 or 3. The FHA analysis does not assume a Loss of Off-Site Power as an initial condition.

SR 3.8.1 .19 This Surveillance demonstrates the DG operation during a loss of offsite power actuation test signal in conjunction with an ECCS initiation signal.
LCO 3.5.2 This LCO does not assume that the onsite electrical power source will start automatically on a loss of voltage signal concurrent with an ECCS initiation signal. Therefore, SR 3.8.1.19 is not applicable.
LCO 3.6.4.3, LCO 3.7.4, and LCO 3.7.5 These LCOs are only required in modes 1, 2, 3, during movement of irradiated fuel assemblies in the secondary containment, and during core alterations. TS 3.8.2 does not apply in modes 1, 2 or 3. The FHA analysis does not assume a Loss of Off-Site Power as an initial condition.

The proposed changes only revise the applicable SRs that are required to consider a DG operable per LCO 3.8.2 Part C As discussed in the responses to items A and B, no changes are required for SR 3.8.1.21, as this SR continues to specify the appropriate criteria for operability of an opposite unit AC Source that is required by a Unit operating in modes 1, 2, or 3.
Part D TSTF-582, "RPV WIC Enhancements," states that LCO 3.5.2, "RPV WIC," does not assume that the onsite electrical power source will start automatically on an ECCS or loss of power signal. Additionally, the FHA analysis does not assume a Loss of Off-Site Power as an initial condition. In an oversight in TSTF-582, not all TS 3.8.1 SRs listed in SR 3.8.2.1 that test automatic start and loading of a diesel generator on an ECCS or loss of offsite power signal were excluded , and the Applicability of TS 3.3.8.1 was not revised to reflect that the LOP instrumentation should not be required to be operable when the associated EOG is not required to automatically start in response to a LOOP.

ATTACHMENT 1 Response to Request for Additional Information RAI 3 (Quad Cities)
Section 8.3.1.6, "Standby Emergency Diesel Generator System, " of the Quad Cities UFSAR states, in part, that the DG system provides emergency source of AC power in the event all normal offsite power becomes unavailable. The system consists of three DGs: 1, 2, and 1/2 (shared DG).
Quad Cities LCO 3.8.1.d requires that the following AC electrical power source be operable when the unit is operating: "The opposite unit's DG capable of supporting the equipment required to be OPERABLE by LCO 3.6.4.3 , LCO 3.7.4 (Unit 2 only) , and LCO 3.7.5 (Unit 2 only)." SR 3.8.1.21 is applicable to the opposite unit's AC electrical power sources and it specifies, in part, the SRs necessary to meet LCO 3.8.1.d.
Quad Cities LCO 3.8.2.b requires that the following AC electrical power source be operable when the unit is shutdown: "One diesel generator (DG) capable of supplying one division of the onsite Class 1E AC electrical power distribution subsystem(s) required by LCO 3.8.8." When a unit is shutdown , Quad Cities LCO 3.8.8 requires: "T he necessary portions of the AC , DC, and the opposite unit's electrical power distribution subsystems shall be OPERABLE to support equipment required to be OPERABLE." Quad Cities SR 3.8.2.1 specifies the SRs in TS 3.8.1 that are necessary to meet LCO 3.8.2.
The licensee proposed to revise Quad Cities SR 3.8.2 .1 as shown in the table below. The proposed changes would make several SRs for AC sources required by TS 3.8.2 no longer applicable . The licensee also proposed to revise Quad Cities TS 3.3.8.1, "Loss of Power (LOP)
Instrumentation," such that LCO 3.3.8.1 would no longer be applicable "[w]hen the associated diesel generator is required to be OPERABLE by LCO 3.8.2, 'AC Sources Shutdown .'" The LAR states that these changes are based on TSTF-582 and TSTF-583-T. However, these travelers and the NRC safety evaluation for TSTF-582 do not address shared AC sources at multi-unit sites. In addition , the LAR does not address the shared AC sources at Quad Cities.
The LAR also proposes , without justification , to delete SRs currently required by SR 3.8.2 .1 (e.g ., Quad Cities SR 3.8.1.7) which are not included in the TSTF-582 or TSTF-583-T changes .
The proposed changes would also make SR 3.8.2.1 inconsistent with SR 3.8.1 .21.

Page 17

ATTACHMENT 1 Response to Request for Additional Information A. For SR 3.8.2.1, identify the currently applicable SRs of TS 3.8.1 that are necessary to meet LCO 3.6.4.3, LCO 3.7.4, LCO 3.7.5, and LCO 3.8.8.

B. For each SR of TS 3.8.1 that would no longer be applicable to TS 3.8.2 under the proposed amendment, explain why the SR is not needed to support the opposite unit or to meet the requirements of LCO 3.8.2. The response should address the requirements in LCO 3.6.4.3, LCO 3.7.4, LCO 3.7.5, and LCO 3.8.8. The response should also identify and address any differences between the events considered in the NRC staffs safety evaluation for TSTF-582 and the Quad Cities design and licensing basis.
C. Identify the changes to SR 3.8.1.21 that are needed to make it consistent with the proposed SR 3.8.2.1. Provide justification to support these changes.
D. In conjunction with the information requested under A, B, and C above, justify the deletion of the following wording from the Applicability of LCO 3.3.8.1: "When the associated diesel generator is required to be OPERABLE by LCO 3.8.2, 'AC Sources Shutdown."'

ATTACHMENT 1 Response to Request for Additional Information Response to RAI 3 (Quad Cities):
Part A Quad Cities Surveillance Requirement (SR) 3.8.2.1 lists the subset of SRs from Technical Specification (TS) 3.8.1, "AC Source - Operating," that are required to be met for alternating current (AC) electrical power sources that are required to be operable by LCO 3.8.2, "AC Sources - Shutdown." LCO 3.8.2 is applicable to a unit that is in modes 4 or 5, or during movement of recently irradiated fuel assemblies in the secondary containment. LCO 3.8.2 requires one offsite circuit between the offsite transmission network and the onsite Class 1E AC electrical power distribution subsystem(s) required by LCO 3.8.8, "Distribution Systems -
Shutdown," and one diesel generator (DG) capable of supplying one division of the onsite Class 1E AC electrical power distribution subsystem(s) required by LCO 3.8.8.
According to LCO 3.0.9 and SR 3.0.5, LCOs and SRs, respectively, are applied individually to each unit at a dual-unit site, such that the operating mode of one unit does not affect the application of the TS to the opposite unit. Therefore, the TS 3.8.1 SRs that are currently required to be met by SR 3.8.2.1 when a unit is in the mode of applicability of SR 3.8.2 are independent of the opposite unit's mode. The applicability of these SRs under the current Quad Cities SR 3.8.2.1 wording (prior to adoption of TSTF-582) is summarized in Table 3A-1.

      *For Unit One, the required DG will be either the Unit 1 DG or the Unit 1/2 (shared) DG.
    **For Unit Two, the required DG will be either the Unit 2 DG or the Unit 1/2 (shared) DG.
LCOs 3.6.4.3, 3.7.4, and 3.7.5 are not applicable to a unit that is in mode 4 or 5 unless recently irradiated fuel is being moved in the shared secondary containment. These LCO's, when applicable, require equipment to be operable that is powered by both the same unit and the opposite unit's AC distribution subsystem(s). For equipment powered by the same unit (e.g., for Unit 1, 1/2B Standby Gas Treatment (SBGT), Control Room Emergency Ventilation (CREV),
and Control Room Emergency Ventilation Air Conditioning (CREV-AC)), the AC Sources required by LCO 3.8.2 support the associated equipment, with applicable SRs specified in the table above. For equipment powered by the opposite unit (e.g ., for Unit 1, 1/2A SBGT), the required opposite unit distribution subsystems are required to be operable by LCO 3.8.8; however, no corresponding opposite unit requirement exists under LCO 3.8.2 for AC Sources.
This is supported by the current bases of LCO 3.8.2 state that:
         "In general, when the unit is shutdown the Technical Specification requirements ensure that the unit has the capability to mitigate the consequences of postulated accidents. However, assuming a single failure and concurrent loss of all offsite or loss of all onsite power is not required. The rationale for this is based on the fact that many Design Basis Accidents (DBAs) that are analyzed in modes 1, 2, and 3 have no specific analyses in modes 4 and 5. Worst case bounding events are deemed not credible in modes 4 and 5 because the energy contained within the reactor pressure boundary, reactor coolant temperature and pressure, and corresponding stresses result in the probabilities of occurrences significantly reduced or eliminated, and minimal consequences . These deviations from OBA analysis assumptions and design requirements during shutdown conditions are allowed by the LCO for required systems."
Therefore, under current Quad Cities TS the applicable SR's of LCO 3.8.1 that are specified to be met under SR 3.8.2 .1 for the AC sources required to be operable by LCO 3.8.2 are those listed in the table above, even if movement of recently irradiated fuel in secondary containment is causing the shutdown unit to be in the mode of applicability of LCOs 3.6.4.3, 3.7.4, and 3.7.5. Adequate power to support the operability of required opposite unit equipment is assured by LCO 3.8.8.
For any operating unit, even if the opposite unit is shutdown, all SR's of LCO 3.8.1 apply to the AC sources required to be operable, which will include one qualified circuit between the offsite transmission network and the opposite unit's onsite Class 1E AC Electrical Power Distribution System and the opposite unit DG capable of supporting LCOs 3.6.4 .3, 3.7.4, and 3.7.5.
Page 20

ATTACHMENT 1 Response to Request for Additional Information Part B Since no changes have been proposed for SR 3.8.1.21, any opposite unit AC sources required by a unit operating in mode 1, 2, or 3 will continue to be subject to the existing set of SRs to establish operability. For multi-unit sites with shared AC distribution systems and sources, the same AC Source (e.g. , a unit or shared DG) may be required for each Unit by different LCOs (e.g. , LCO 3.8.1 or LCO 3.8.2); however, the basis for the equipment being required to be operable is different for an operating unit versus a shutdown unit. Since the operating unit must still have the capability to mitigate the effects of Design Basis Accidents (OBA) analyzed for operating conditions (e.g. OBA Loss of Coolant Accident), all of the requirements associated with DG automatic start in response to ECCS or LOOP signals, time to achieve rated voltage and frequency, and load sequencing continue to be required. Thus, no changes to SR 3.8.1 .21 are appropriate or proposed .
As described in the Safety Evaluation for TSTF-582 (Reference 1) and supported by the LOP Variation model Safety Evaluation (Reference 2), the DGs supporting a shutdown unit (operating in mode 4, 5, or during movement of recently irradiated fuel in secondary containment) may be manually started and loaded in response to a Reactor Pressure Vessel (RPV) draining event. Furthermore, the essential consideration for the events assessed in Reference 1, namely that the FHA does not assume a LOOP and that the minimum Drain Time permitted for any duration by LCO 3.5.2 is 1 hour, are consistent with the Quad Cities licensing basis. The ability of each required DG to support the required loads via manual start and loading continues to be demonstrated by the SRs that are retained under the proposed revision to SR 3.8.2.1. Additionally, for the Fuel Handling Accident, no credit in the analysis is taken for the operation of SBGT, GREV, or GREV-AC (Reference 4 ). Equipment required by LCOs 3.6.4.3, 3.7.4, and 3.7.5 will continue to be supported by operable distribution subsystems specified by LCO 3.8.8. The Quad Cities licensing basis does not include any additional events requiring automatic start of DGs for a shutdown unit that have not already been considered in the safety evaluation for TSTF-582 (i.e. , Fuel Handling Accident, draining event in mode 4 or 5).
The proposed LAR does not affect which AC sources will be required via LCO 3.8.2 to support the distribution systems required operable via LCO 3.8.8, but only revises the applicable SRs that are required to consider a DG operable for LCO 3.8.2 (though additional SRs may apply to the same DG and its associated start logic if required by an operating unit via SR 3.8.1.21 ).
Based on the above considerations, justification for deletion of each proposed SR of LCO 3.8.1 from the list of SRs required by the DG(s) required to be operable by LCO 3.8.2 is provided:
SR 3.8.1.8 This surveillance verifies the DG ability to achieve required voltage and frequency within 13 seconds. The 13 second timeframe is not required to support manual start of the DG in response to the postulated events in mode 4 or 5, and the ability of the DG to be manually started and loaded continues to be demonstrated by SR 3.8.1.2. If an operating unit requires the same DG to be operable, this surveillance will continue to be applicable for the operating unit via SR 3.8.1.21 . This SR is equivalent to SR 3.8.1.7 from NUREG-1433 Revision 4, with the exception that the Quad Cities SR includes a note allowing the performance of this test for the common DG to satisfy this SR for both Units. This SR is assessed for deletion from the NUREG-1433 STS SR 3.8.2.1 in Reference 2.
SR 3.8.1 .12 Page 21

ATTACHMENT 1 Response to Request for Additional Information This surveillance verifies, in part, the automatic start and loading of a DG on a LOOP signal. As previously discussed, response to the postulated events in mode 4 and 5 does not require automatic start and loading of a DG. If an operating unit requires the same DG to be operable, this surveillance will continue to be applicable for the operating unit via SR 3.8.1.21 . This SR is equivalent to SR 3.8.1 .11 from NUREG-1433 Revision 4, with the exception that Quad Cities does not include the verification of auto-connected loads through a load sequencer (as the Quad Cities design does not have this feature). This SR is approved for deletion from the NUREG-1433 STS SR 3.8.2.1 in Reference 1.
SR 3.8.1 .14 This surveillance verifies that the required DG's noncritical automatic trips are bypassed on an actual or simulated loss of voltage signal on the emergency bus concurrent with an actual or simulated ECCS initiation signal. Since the requirement for operable ECCS initiation signals is proposed for removal from LCO 3.3.5.2, removal of this surveillance from the list of those surveillances required for a DG supporting LCO 3.8.2 establishes consistency. Consistent with the assessment provided in Section 3.6 of Reference 1, LCO 3.8.2 and LCO 3.5.2 will, upon an actual LOOP, continue to require the restoration of an RPV injection source capable of operating without offsite power within a timeframe adequate for responding to a vessel draining event. If an operating unit requires the same DG to be operable, this surveillance will continue to be applicable for the operating unit via SR 3.8.1.21. This SR is equivalent to SR 3.8.1.13 from NUREG-1433 Revision 4. This SR is approved for deletion from the NUREG-1433 STS SR 3.8.2.1 in Reference 1.
SR 3.8.1.16 This surveillance demonstrates that the DG can restart from a hot condition, such as subsequent to shutdown from normal surveillances, and achieve the required voltage and frequency within 13 seconds. The 13 second timeframe is not required to support manual start of the DG in response to the postulated events in mode 4 or 5, and the ability of the DG to be manually started and loaded continues to be demonstrated by SR 3.8.1.2 . If an operating unit requires the same DG to be operable, this surveillance will continue to be applicable for the operating unit via SR 3.8.1 .21. This SR is equivalent to SR 3.8.1 .15 from NUREG-1433 Revision 4, with the exception that the Quad Cities SR includes a note allowing the performance of this test for the common DG to satisfy this SR for both Units. This SR is assessed for deletion from the NUREG-1433 STS SR 3.8.2.1 in Reference 2.
SR 3.8.1 .18 This surveillance verifies the interval between each sequenced load block is <::90% of the design interval for each load sequence time delay relay. This logic is associated with automatic start and loading of an EOG in response to an ECCS initiation signal concurrent with a LOOP. Since the requirement for operable ECCS initiation signals is proposed for removal from LCO 3.3.5.2, removal of this surveillance from the list of those surveillances required a DG supporting LCO 3.8.2 establishes consistency. Manual loading of the DG will continue to be able to be performed by licensed operators in response to the postulated events in mode 4 and 5 or during movement of recently irradiated fuel in secondary containment. This SR is equivalent to SR 3.8.1 .18 from NUREG-1433 Revision 4. This SR is assessed for deletion from the Page 22

ATTACHMENT 1 Response to Request for Additional Information NUREG-1433 STS SR 3.8.2.1 in Reference 2.
SR 3.8.1 .7 This SR was inadvertently removed from the list of SRs required to be performed under SR 3.8.2.1 and will be retained . Attachment 4 provides the corrected markup of SR 3.8.2.1. will replace in its entirety Attachment 2.4 of the original submittal. However, the only change to the markup is the correction to SR 3.8.2.1 on Page 3.8.2-5.
Part C As discussed in the responses to Parts A and B, no changes are required for SR 3.8.1.21, as this SR continues to specify the appropriate criteria for operability of an opposite unit AC Source that is required by a unit operating in modes 1, 2, or 3.
Part D As described in Part B, the DGs supporting a shutdown unit (operating in mode 4, 5, or during movement of recently irradiated fuel in secondary containment) may be manually started and loaded in response to a Reactor Pressure Vessel (RPV) draining event.
TSTF-582 did not include all the TS changes needed to reflect that TS 3.8.2 does not require automatic start and loading of a DG within 13 seconds on an ECCS initiation signal or LOOP signal. TSTF-583-T addressed these additional changes, which included the revision of the Applicability of LCO 3.3.8.1 to remove the currently specified condition "When the associated diesel generator as required to be OPERABLE by LCO 3.8.2, 'AC Sources - Shutdown."'
TS 3.3.8.1, "Loss of Power (LOP) Instrumentation," is currently applicable in modes 1, 2, and 3, and when the associated DG is required to be operable by TS 3.8.2. Implementation of TSTF-582 revises TS 3.8.2 to no longer require automatic start and loading of a DG on a LOOP signal. Consequently, the instrumentation that generates the LOOP signal should not be required to be operable when the DG is required to be operable by TS 3.8.2. As a result, the deletion of the condition related to TS 3.8.2 in the applicability of LCO 3.3.8.1 is appropriate .

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

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.
