The above cited examples demonstrate that it is the intent for the conversion to he improved technical specifications to remove detailed plant requirements en they can be adequately controlled in other regulatory controlled documents. It is PPL's position that because the conversion from SSES CTS o SSES ITS format is requiring a much more detailed table defining each offsite and onsite timer, the information is more appropriately controlled in Ihe SSES ITS Bases. This change can be made on a
,planl specific basis because iSSES is designed with lindividual load timers which I
have dillerent settings and Iunctions. Furthermore, because the information is being relocated to the SSES ITS Bases, the SSES ITS Bases Control program will ensure that any change to SSES ITS Bases willnot result in a change to the corresponding SSES ITS requirement to have these timers lunction and protect the associated AC Power Source.

The change as stated in the JFD PA, is being made to eliminate the need to "perform" the test during and following an equalizing charge because data taken during the perfonnance of the equalizing charge ould be acceptable but not representative. Because the battery is on an equalize charge, measuring the terminal voltage will provide no aninglul or trendable data. The SR requirements will be met during the equalizing charge therefore, compliance with the SR is not being aken exception tomnty the need to perform the test at the specified interval is being extended.

INSERT B3.~1 (NRC RAI 3.8.142):
A,2 Required Action A.2, which only applies if one 4.16 kV ESS bus cannot be powered from any offsite source, is intended to provide as'surance that an event with a coincident single failure of the associated DG does not result in a complete toss of safety function of critical systems. These features (e.g., system, subsystem, division, component, or device) are designed to be powered from redundant safety related 4.16 kV ESS buses.
Redundant required features failures consist of inoperable features associated with an emergency bus redundant to the emergency bus that has no offsite power. The Completion Time for Required Action A.2 is intended to allow time for the operator to evaluate and repair any discovered inoperabilities. This Completion Time also allows an exception to the normal "time zero" for beginning the allowed outage time "dock." In this Required Action the Completion Time only begins on discovery that both:
- a. A4.16 kV ESS bus has no offsite power supplying its loads; and
- b. A redundant required feature on another 4.16 kV ESS bus is inoperable.
If, at any time during the existence of this Condition (one offsite circuit inoperable) a required feature subsequently becomes inoperable, this Completion Time would begin to be tracked.
Discovering no offsite power to one 4.16 kV ESS bus of the onsite Class 1E Power Distribution System coincident with one or more inoperable required support or supported features, or both, that are associated with any other emergency bus that has offsite power, results in starting the Completion Times for the Required Action.
Twenty-four hours is acceptable because it minimizes risk while allowing time for restoration before the unit is subjected to transients associated with shutdown.
The remaining OPERABLE offsite circuits and DGs are adequate to supply electrical power to the onsite Class 1E Distribution System. Thus, on a component basis, single failure protection may have been lost for the required feature's function; however, function is not lost The 24 hour2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> Completion Time takes into account the component OPERABILITYof the redundant counterpart to the inoperable required feature.

low level alarms on DG day tanks are set slightly below this level and will provide adequate time for operators to investigate and correct or compensate for a diesel fuel oil transfer pump failure.
Additionally, calculations supporting 45 minutes of DG operation are based on fuel oil consumption calculations that are very conservative. Specifically. the DG post accident load for all DGs is assumed to be equal to the OG with the highest post accident load: OG fuel consumption rates're assumed to be equal to the highest consumption rate observed for any of the DGs: and, assumptions about fuel oil specific gravity included using the highest heat value fuel during observations of fuel consumption r ates (lowest fuel consumption) and lowest heat value fuel during accident conditions (highest consumption). Therefore. minimum day tank volumes based on 45 minutes of OG operation at the post accident load does not have a significant impact on safety.

SUSQUEHANNA UNIT 1 AND 2 23 Revision 0. 07/31/96
INSERT (NRC RAI 3.8.1-02):
L.17 SSES CTS 3.8.1.1 requires two physically independent circuits between the offsite transmission network and the onsite Class 1E distribution system. Although the SSES CTS does not define the specific lineup required for the offsite circuits, it is PP&L's current position that an offsite circuit is considered Operable when it can supply all four 4.16 kV ESS Buses. SSES ITS 3.8.1 also requires two qualified circuits between the offsite transmission network and the onsite Class 1E AC Electrical Power Distribution System, but in the SS rable source is only required to supply three of the .16 kV ESS buses needed to be powered or capable of being powered, provided that all 4.16 kV buses are supplied by acr Opereb!9 offsite circuit. This change is acceptable because it maintains the req irements of General Design Criteria (GDC) 17. GDC 17 specifies that "Each of o~c y<,'< ese circuits shall be designed to be available in sufficient time following a loss of all onsite alternating current power supplies and the other offsite electric power circuit, to assure that specified acceptable fuel design limits and design conditions of the reactor coolant pressure boundary are not exceeded. One of these circuits shalt be designed to be available within a few seconds following a loss-of-coolant accident to assure that core cooling, containment integrity, and other vital safety functions are maintained." As stated, the SSES ITS Bases definition of what constitutes an Operable Offsite circuit will allow two of the four required ESS Buses to only have a single Operable Offsite circuit. Reviewing the GDC 17 requirements, it can be shown that this configuration will meet those requirements. First, in the loss of power event where all onsite power sources were lost, and the other Offsite Source is tost, the three available 4.16 kV ESS Buses will remain powered. For a Loss of Power Event assuming no other single failures, the three available 4.16 kV ESS Buses'are sufficient to assure that specified acceptable fuel design limits and design conditions of the reactor coolant pressure boundary are not exceeded.
Finally, with the automatic transfer capability provided for the Offsite Sources (tested in SSES ITS SR 3.8.1.8), one Offsite Power Source will be available (within the time assumed in the Accident Analysis) to assure that core cooling, containment integrity, and other vital safety functions are maintained.
The change also inv Ives adding SSES ITS Required Action A.2 to ensure that with an Offsite Circuit i rable no redundant required feature is inoperable such that a total loss of functi nII uld occur. Furthermore, a note is added to SSES ITS Required Action dentifying that if one offsite circuit and one DG are inoperabi ~
and it results in a total loss of power to a 4.16 kY ESS Bus then Actions per LCO 3.8.7 shall be taken. These. changes are necessary to ensure that the proper actions are taken with the loss of AC Sources considering the allowance provided by the definition of Operability.
Based on the fact that the allowed conditions meet GDC 17 requirements and appropriate modifications have been made to the SSES CTS Actions to ensure appropriate actions are taken with the ioss of AC Sources, this less restrictive change will have no measurable effect on safety.

Note 2 modifies this Surveillance by stating that momentary transients because of changing bus loads do not invalidate this test. Similarly. momentary power factor transients do not invalidate the test.
Note 3 indicates that this Surveillance should be conducted on only one OG at a time in order to avoid common cause failures that might result from offsite circuit or grid perturbations.
Note 4 stipulates a prerequisite requi rement for performance of this SR. A successful DG start must precede this test to credit satisfactory performance.
Note 5 provides the allowance that OG E, when not aligned as substitute for DG A, B. C and 0 but being maintained Operable, may use the test facility to satisfy loading requirements in lieu of synchronization with an ESS bus.
Note 6 allows a single test (instead of two tests, one for each unit) to satisfy the requirements f'r both units. with the OG synchronized to the 4. 16 kV ESS bus of Unit 1 for cre eriodic test and synchronized to the 4. 16 kV ESS bus of e nit 2 during the next periodic test. This is acceptable because the purpose of the test is to demonstrate the ability of the OG to operate at its continuous rating (with the exception of'G E which is only required to be tested ~t the continuous rating of OGs A through 0) and this attribute is tested at the required Frequency. Each unit's circuit breakers and breaker control circuitry. which are only bei~
tested every second test (due to the staggering of the tests). historically have a very low failure rate.

This more restrictive change is acceptable because introduce any operation which is unanalyzed while requiring more it does not conservative test acceptance criteria than currently required.
Therefore. this change has no negative impact on safety.
SSES CTS SRs require the DGs to achieve and mafntain a frequency of 60 a 3 Hz (a 5C) during DG start and load testing. The equfvalent SSES ITS SRs require that the DGs achieve a frequency between 58.8 Hz and 61.2 Hz. These values are equal to + 2L of the 60 Hz nominal frequency and are derived from the recomendations found in Regulatory Guide 1.9. Rev 3. Section 1.4.
n conjunctio with the more restrictive minimum and maximum steady state requency, SSES ITS S that include a DG start time requirement re modffied to incl e clarificatio that only the minimum vo age and frequency r uirements (vo age ~ 3793 V and frequency 58.8) must be met thin the all starting time ut ',
that min and maximum volt e and frequen y limits must be achieve after steady state nditions are cached.

'dditionally. calculations supporting 45 minutes of OG operation are based on fuel oil consumption calculations that are very conservative. Specifically, the DG post accident load for all DGs is assumed to be equal to the OG with the highest post accident load: OG fuel consumption rates are assumed to be equal to the highest consumption rate observed for any of the OGs: and, assumptions about fuel oi 1 specific gravity included using the highest heat value fuel during observations of fuel consumption rates (lowest fuel consumption) and lowest heat value fuel during accident conditions (highest consumption).

This Surveillance provides assurance that the fuel oil transfer pump is OPERABLE. the fuel oil piping system is intact. the fuel delivery piping is not obstructed, and the controls and control systems for automatic fuel transfer systems are OPERABLE.
The Frequency for this SR is 31 days because the design of the fuel transfer system requires that the transfer pumps operate automatically in order to maintain an adequate volume of fuel oil in the day tanks.

This SR is modified by a Note. The reason for the Note is that, during operation with the reactor critical, performance of this SR could cause perturbations to the electrical distribution systems that could challenge continued steady state operation and, as a result, plant safety systems. This Surveillance tests the applicable logic associated with Unit 1. The comparable test specified in Unit 2 Technical Specifications tests the applicable logic associated with Unit 2. Consequently, a test must be performed within the specified Frequency for each unit. As the Surveillance represents separate tests, the Note specifying the restriction for not performing the test while the unit is in MODE 1 or 2 does not have applicability to Unit 2.

This Surveillance demonstrates that the DG automatically starts and achieves the required voltage and frequency within the specified time (10 seconds) from the design basis actuation signal (LOCA signal) and operates for a 5 minutes.
The 5 minute period provides sufficient time to demonstrate stability. SR 3.8.1.12.d and SR 3.8.1.12.e ensure that permanently connected loads and emergency loads are energized from the offsite electrical power system on a LKA signal without loss of offsite power.
The requirement to verify the connection and power supply of permanent and autoconnected loads is intended to satisfactorily show the relationship of these loads to the loading logic for loading onto offsite power. In certain circumstances. many of these loads cannot actually be connected or loaded without undue hardship or potential for undesired operation. For instance. ECCS injection valves are not desired to be stroked open, high pressure injection systems are not capable of being operated at full flow. or RHR systems performing a Cecay heat removal function are noh desired to be realigned to the ECCS mode of operation. In lieu of actual demonstration of the connection and loading of these loads, testing that adequately shows the capabi lity of the OG system to perforn these functions is acceptable.

REQUIREMENTS operations or at some other outage. with intervals between tests not to exceed 24 months.
This SR is modified by a Note which allows the performance of a modified performance discharge test in lieu of a service test once per 60 months.
The modified performance discharge test is a simulated duty cycle consisting of just two rates: the one minute rate published for the battery or the largest current load of the duty cycle. followed by the test rate employed for the performance test. both of which envelope the duty cycle of the service test. Since the ampere-hours removed by a rated one minute discharge represents a very small portion of the battery capacity, the test rate can be changed to that for the performance test without compromising the results of the performance discharge test. The battery terminal voltage for the modified performance discharge test should remain above the minimum battery terminal voltage specified in the battery service test for the duration of time equal to that of the service test.
A modified discharge test is a test of the battery capacity and its ability to provide a high rate. short duration load (usually the highest rate of the duty cycle). This will often confirm the battery's ability to meet the critical period of the load duty cycle, in addition to determining its percentage of rated capacity. Initial conditions for the modified performance discharge test should be identical to those specified for a service test.

The acceptance criteria for this Surveillance is consistent with IEEE-450 (Ref. 8) and IEEE-485 (Ref. 11). These references recomtend that the battery be replaced if its capacity is below BOZ of the manufacturer's rating. A capacity of 80Z shows that the battery rate of deterioration is increasing. even if there is ample capacity to meet the load requirements.
The Frequency for this test is normally 60 months. If the battery shows degradation. or life if the battery has reached 85Z of its expected service and capacity is < 100Z of the manufacturer's rating, the Surveillance Frequency is reduced to 12 months. However. if the battery shows no degradation life.
but has reached 85Z of its expected service the Surveillance Frequency is only reduced to 24 months for batteries that retain capacity m 100Z of the manufacturer's rating. Oegradation is indicated. according to IEEE-450 (Ref. 8). when the battery capacity drops by more than 10Z relative to its capacity on the previous performance test or when it is 10Z below the manufacturer's rating.

Starting transients that exceed the new and more restrictive maximum voltage and frequency limits will not be considered failure to meet acceptance criteria.

T HN A HAN - R TR T V M.1 (Unit 2 Only) SSES CTS 3.8.1.1 requires Ooerability of four diesel generators and the two offsite circuits that'upport the Unit's Class lE distribution system. SSES ITS 3.8.1 retains these requirements and. for Unit 2. adds a specific requirement for the OG(s) and qualified circuits needed to support the Unit 1 onsite Class 1E AC electrical power distribution subsystem(s) required b LCO 3.8.7, Oistribution Systems-Operating. This change is necessary because some equipment needed to meet Unit 2 accident analysis is powered from the Unit 1 AC Electrical Power System.
Currently, SSES CTS 3.8.3.1 for Unit 2 recognizes this requirement by requiring Operability of those Unit 1 busses that support equipment required in the Unit 2 accident analysis. However.
Unit 2 SSES CTS establishes requirements for the Unit 1 AC sources only to the extent that the definition of Operability requires the normal and emergency power sources of the Unit 1 equipment to be Operable. Therefore. for completeness. the Unit 1 AC sources required to support Unit 2 have been added to SSES ITS 3.8.1.
This is a more restrictive change because specifying an explicit allowed out of service time and Surveillance Requirements for the Unit 1 AC sources make this an additional restriction on, plant operations. SSES ITS SR 3.8.1.21 and a Note to the Surveillance requirements have been added to ensure that the Unit 1 AC sources are properly tested and that the appropriate SRs are applicable for each units AC sources. These requirements are not being added to the Unit 1 SSES ITS because there is no AC equipment required by the Unit 1 accident analysis that is power from the Unit 2 AC Sources. This more restrictive change is acceptable because it does not introduce any operation which is un analyzed awhile establishing more complete requirements for AC sources than currently required. merefore. this change has no negative impact on safety.
SSES CTS 4.8.1.1.2.d.12 requires verification that each diesel generator loading sequence timer shown in Table 4.8.1.1.2-2 is Operable with its setpoint within 10K of its design setpoint, except for the RHR pump timers. which may have a tolerance of
+ 20K. - 104. SSES ITS SR 3.8. 1. 18 expands this requirement to include verification of the load timers used to sequence ECCS loads when offsite power is available. The timers associated with offsite power serve the same purpose as the timers associated with the DG, i.e., prevent simultaneous equipment starting from SUSQUEHANNA UNIT 1 ANO 2 Revision 0, 07/31/96

SSES ITS LCO 3.8.1. Condition G. provides equivalent direction by ensuring that the more appropriate Actions in LCO 3.8.7 for loss of power to an ESS bus are entered when an inoperable DG and two inoperable offsite circuits result in loss of power to one 4.16 kV ESS bus.

Individual load timers are tested by each of the SRs that verify sequential loading of the DG or 4. 16 kV ESS bus and are calibrated as required by SR 3.8.1.18. The failure of an individual load timer would result in the associated OG or offsite sources being declared inoperable. as appropriate.

Although no power factor requirements are established by this SR, the OG is normally operated at a power factor between 0.8 lagging and 1.0. The 0.8 value is the design rating of the machine, while 1.0 is an operational limitation to ensure circulating currents are minimized.
The load band is provided to avoid routine overloading of the OG. Routine overloading may result in more frequent teardown inspections inbotanical accordance with vendor recomendations in order to maintain DG OPERABILITY.

This Surveillance provides assurance that the fuel oil transfer pump is OPERABLE. the fuel oil piping system is intact. the fuel delivery piping is not obstructed. and the controls and control systems for automatic fuel transfer, systems are OPERABLE.
The Frequency for this SR is 31 days because the design of the fuel transfer system requires that the transfer pumps operate automatically in order to maintain an adequate volume of fuel oil in the day tanks. This Frequency allows this aspect of DG Operability to be demonstrated during or following routine OG operation.

Transfer of each 4.16 kV ESS bus power supply from the normal offsite circuit to the alternate offsite circuit demonstrates the OPERABILITY of the alternate circuit distribution network to power the shutdown loads. The 24 month Frequency of the Surveillance is based on engineer ing judgment taking into consideration the plant conditions required to perform the Surveillance. and is intended to be consistent with expected fuel cycle lengths.
Operating experience has shown that these components usually pass the SR when performed on the 24 month Frequency.

P.14 The NUREG-1433. Revision 1, SR 3.8. 1. 18 was revised to reflect the SSES design which uses individual load timers versus a load sequencer as assumed in the NUREG. In conjunction with this change. the Bases for LCO 3.8.1 were modified to include a list of DG and offsite power load timers and their required tolerances.
SrL 5,5.i.tt wgq Additionally. a note was added that specifies that load timers o 4o associated with equipment that has automatic initiation capability c,ls~ disabled are not required to be Operable because if the load does

P.15 The NUREG-1433. Revision 1. SR 3.8.1.13.d and 3.8.1.13.e.
requirements for testing override features associated with high crankcase pressure and the start failure relay are deleted because SSES DGs do not have these features. This change has been made to ensure that Improved Technical Specifications account for the SSES design. Therefore, this change does not represent a significant or generic deviation from NUREG 1433.
P. 16 The NUREG-1433, Revision 1, SR 3.8.1.14. requirement that the DG full load endurance run be conducted operating at a specified power factor is deleted. This change is acceptable because SSES endurance runs are conducted at DG power levels significantly higher than peak post accident DG loads. Therefore. SR 3.8.1.14.
even if conducted at a unity power factor. is conducted at a kYA rating that exceeds the peak post accident kVA loading. This change has been made to ensure that Improved Technical Specifications account for the SSLS design which has DG ratings higher than the maximum post accident loads. Therefore. this change does not represent a significant or generic deviation 1433.

INSERT NRC RAI 3.8.1-42:
P.13 NUREG 1433 SRs 3.8.1.9 and 3.8.1.10 specify that test be performed at or below a specific power factor to ensure the DG is tested under load conditions, that are as close to design basis conditions as possible. The same SRs for SSES ITS, do not include the power factor testing restriction. This deviation from a NUREG 1433 requirement is necessary because calculations show that placing the limiting load on the DG at a design power factor may result in the generator output voltages exceeding the setting of the overvoltage relay. Furthermore, there is a concern that operation requiring adjustment and maintenance of a specific power factor with the DG in parallel with the offsite source may result in undesired interactions with the automatic tap changer for the SU Transformer. To avoid this condition it would require the tap changer to be turned off which would limit the capability of the offsite circuit. The change is acceptable because although a the full load rejection test at the limiting power factor provides the most limiting test for the DG excitation system, the combination of other surveillance tests including the full load rejection test without the added restriction of the limiting power factor, the LOCA/LOOP Test, and the 24 hour2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> run for the DG, including the 2 hour2.314815e-5 days <br />5.555556e-4 hours <br />3.306878e-6 weeks <br />7.61e-7 months <br /> run at the 2000 hour0.0231 days <br />0.556 hours <br />0.00331 weeks <br />7.61e-4 months <br /> rating of the DG provide a comprehensive and representative testing methodology which ensures the DG is capable of responding to a Design Basis Event.
The proposed alternative to the testing methodology established in NUREG 1433, is further supported based on the fact that power factor is not adjustable when the DG is operating in the emergency mode (isochronous). Finally, it is PPL's position that the specified surveillances would detect degradation of the generator or its excitation system through larger than normal voltage droPs, delayed voltage recovery or other operating voltage instabilities that would be observed during the performance of the surveillance.
Based on the above discussion, the NUREG 1433 Surveillance Requirements have been determined to be not necessary based on the SSES unique design conditions.

Note 2 provides an allowance that this SR does not have to be perfo with the normally aligned OG when the associated 4.16 kV ESS bus is tested using diesel generator E.

Specifically, when DG E is tested with a Unit 1 4.16 kV ESS bus, the attributes of the normally aligned OG, although not tested with the Unit 1 4.16 kV ESS bus, are tested with the Unit 2 4.16 kV ESS bus within the 24 month Frequency.

'Timers. Failure of a timer identified as an offsite power timer may result in both offsite sources being inoperable. Failure of any other timer may result fn the associated OG being inoperable.
INSERT: 8 3.8-30-03 This SR is modified by a Note that specifies that load timers associated with equipment that has automatic initiation capability disabled are not required to be Operable. This is acceptable because if the load does not start automatically, the adverse effects of an improper loading sequence are eliminated.

low level alarms on DG day tanks are set slightly below this level and will provide adequate time for operators to investigate and correct or compensate for a diesel fuel oil transfer pump failure.
Additionally. calculations supporting 45 minutes of OG operation are based on fuel oil consumption calculations that are very conservative. Specifically. the DG post accident load for all DGs fs assumed to be equal to the OG with the highest post accident load; DG fuel consumption rates are assumed to be equal to the highest consumption rate observed for any of the OGs: and.
assumptions about fuel oil specific gravity included using the highest heat value fuel during observations of fuel consumption rates (lowest fuel consumption) and lowest heat value fuel during accident conditions (highest consumption). Therefore, minimum day tank volumes based on 45 minutes of DG operation at the post accident load does not have a significant impact on safety.

In the event of a DBA coincident with a loss of offsite power, the OGs are required to supply the necessary power to ESF systems so that the fuel, RCS, and containment design limits are not exceeded.
This Surveillance demonstrates DG operation, as discussed in the Bases for SR 3.8.1.11, during a loss of offsite power actuation test signal in conjunction with an ECCS initiation signal. In lieu of actual demonstration of connection and loading of loads, testing that adequately shows the capability of the OG system to perform these functions is acceptable.
~
This testing may include any series of sequential, overlapping, or total steps so that the entire connection and loading sequence is verified.
The Frequency of months'akes into consideration plant conditions required to perform the Surveillance and is intended to be consistent with an expected fuel cycle length.
This SR is modified by two Notes. The reason for Note 1 is to inimize wear and tear on the DGs during testing. For the rpose of this testing, the 06s must be started from tandby conditions, that is, with the engine coolant and oil Qq,o (gL being continuously circulated and temperature maintained consistent with manufacturer recomnendations. e reas or oe a p orm>n e ur e> an e woul remov a re ui d of ice ertur the el ctriAl (continued)

Furthermore. NRC and PP8L resources associated with processing license amendments to these Administrative Control requirements will be reduced. This change is a less restrictive administrative change with no impact on safety.
Note that requirements for accelerated testing associated with some SRs are eliminated based on justifications provided in discussions of changes L.6 for ITS 3.8.1 and LE 2 for ITS 3.8.3 for the following tests: CTS 4.8.1.1.2.a.l. 4.8.1.1 2.a.2, and ~

~
scope of tests subjected to accelerated testing.
LA.2 SSES CTS 4.8.1.1.2.a.6 requires periodic verification that the diesel generators are aligned to provide standby power to the associated emergency busses. SSES ITS 3.8.1 does not provide a specific SR to perform this verification because this is an integral part of the Operability of the DGs as defined in the Bases for SSES ITS 3.8.1. Procedural controls on DG standby alignment and the definition of Operability in the Bases are sufficient to ensure the DG remains aligned to provide standby power. The Bases require change control in accordance with the SSES ITS 5.5.10, Bases Control Program. This approach provides an effective level of regulatory control and provides for a more appropriate change control process. The level of safety of facility operation is unaffected by the change because there isNRCno change in the requirement to have DGs Operable. Furthermore.

SSES CTS CclM&04 tcl\J) 3.8.3.2 for Unit 2 recognizes this requirement by requiring Operabi lity of those Unit 1 busses that support equipment required in the Unit 2 accident analysis. However. Unit 2 SSES CTS establishes requirements for the Unit 1 AC sources only to the extent that the definition of Operability requires the normal ard emergency power sources of the Unit 1 equipment to be Operable.
Therefore, for completeness'he Unit 1 AC sources required to Z+ c~~ support Unit 2 have been added to SSES ITS 3.8.2. This is a more su g>> p c ~ hL a.t. restrictive change because specifying explicit allowed out of c cid t<ea 4-

L.2 The Surveillance Frequencies for SSES CTS 4.8.1.1.2.a.2 and 4.8.1.1.3.a.2 (verifying level in the DG fuel oil storage tank) and 4.8.1.1.2.a (verifying air receiver pressure) are currently governed by SSES CTS Table 4.8.1.1.2-1; therefore, the test frequencies are subject to accelerated testing based on failure rate of DG start tests. SSES ITS SR 3.8.3. 1 and SR 3.8.3.4, respectively. separate the required frequency for these tests from accelerated testing based on DG start failures because DG start failures are not indicators of an inability to maintain level in the storage tank or maintain adequate air receiver pressure. If either of these parameters causes a DG start failure. the problem can be verified to be corrected without the need for more frequent testing. Therefore, accelerated testing following failure of these particular feature does not result in accumulating experience demonstrating DG starting reliability has improved.
This change has no impact on safety.
L.3 SSES CTS 3.8. l. l.b.2 requires that each Operable DG have a separate fuel oil storage tank containing a minimum of 47,570 gallons of fuel for each DG A. B, C and D and 60.480 gallons of fuel for DG E. These volumes were calculated to ensure sufficien:
fuel oil is available for each DG to operate for 7 days at the continuous rating. SSES ITS SR 3.8.3.1 requires that each Operable DG have a separate fuel oil storage tank containing a minimum of 44.900 gallons of fuel for each Operable DG with the same limit applicable to DG E. The values used in SSES ITS are calculated using the alternate method in Regulatory Guide 1. 137 and is designed to ensure a sufficient fuel oil is available for each DG to operate for 7 days at the maximum post accident load profile. This change is acceptable because use of the post accident load profile method for calculating minimum fuel oil nventory conforms to recommendations in RG 1.137. Specifically.

Section 9.5.4 (Ref. 1). The maximum load demand is calculated using the assumption that at least three OGs are available. This onsite fuel oil capacity is sufficient to operate the DGs for longer than the time to replenish the onsite supply from outside sources.
Fuel oil is transferred from storage tank to day tank by a transfer pump associated with each storage tank.
Independent pumps and piping preclude the failure of one 4~ ~4eg pump. or the rupture of any pipe. valve, or tank to result CLM ~a ~~ in the loss of more than one OG. All outside tanks, pumps.

p.pq NUREG 1433 SR 3.8.3.3 specifies the requirements for Diesel Fuel Oil sampling and analysis and specifically states that the fuel oil is sampled and analyzed "in accordance with" the applicablc standard. SSES ITS SR 3.8.3.3 specifies the required sample, but states that fuel oil is sampled and analyzed "following the guidelines of" the applicable standards..This change is necessary because thc NRC accepted Diesel Fuel Oil standards arc out of date with current laboratory requirements and require numerous exceptions which prevent thc verbatim compliance with the requirements. The following provides some examples of the exceptions necessary:
- 1) Tests are written for other types of fuel and applied to DFO which creates problems. An example of this is the particulate test standard which is written for Aviation Fuel. This test rcquircs a 10 liter sample to be filtered and then weighed.
Because of the difference iri fuel oils, the filter paper is clogged long before a 10 liter sample can be poured through. Therefore, a smaller quality of fuel oi! must be used. This represents a deviation.
- 2) Some standards reference use of specific equipment which is some times out dated or not the preferred equipmcnt. For example:
A. Mercury Thermometers are required for some standards. Mercury must be treated as a controlled substance at the power plant. Over the past several ars other measuring devises besides mercury thermometers are availabtc years
~
which provide. the required accuracy and do not represent a threat to personnel or thc power plant.
B. Solvents which are no longer allowed for industrial usc such as chromi; acid are specified by some standards.
Some standards require the usc of out dated testing equipment which hai been replaced with automated testing equipment which will provide morc accurate results. This leads:o less accurate analysis and more unneces>>ri costs to the utility requiring contracted testing laboratories to use labor intensive testing techniques.
- 3) Some stan S tandards are conflicting ~iih uher standards or instrument manufactur~:i, recommendations. For example:
A. Analysis s tandards specie the uw of certain groups of solvents for c eaning while standards for bottle preparation specifies other soliivcnls.
An exception is needed to bc i~ken for one of thc standards to resolve '..":
conflict.
B.
B Analysissis sstandards specity the um of acid for cleaning some instrumcmi lc thcc Instrument wh'le ils m mend usc of acids.
Manufacturer does not recommen Exceptions should be taken to preserve the warranty t on thee instrument.
in
Based on the above cited examples and the recognition that there are other exceptions that are required, PPL has determined that it is necessary to change the wording of the SSES lTS to identify that the guidelines of the specified standards are followed and not state that samples are taken and analyzed in accordance with the standards. The change to the NUREG 1433 wording is considered acceptable because the exceptions to the standards willbe stated in the Diesel Fuel Oil Testing Program and controlled under 10 CFR 50.59 hich epresents an equivalent level of regulatory control as the SSES ITS Bases without adding an unnecessary and potentially confusing level of detail to the SSES l S. T.
Therefore, based on plant specific concerns with the implementation of the requirements of the specified standards, the proposed change is needed for the plant specific implementation of NUREG 1433 at SSES.

Additionally. although fuel oil in the storage tank for the fifth diesel generator is not assumed to be available. the fifth storage tank is normally filled and transfer capability between this fuel oil storage tank and each of the other tanks is demonstrated to function very frequently. Finally. SSES is located in an industrial area that is easily accessible; therefore. additional diesel fuel will be readily obtained in less than 7 days following an accident. Therefore. this change has no impact on safety.

L.4 SSES CTS 4.8.1.1.2.a.7 and 4.8.1.1.3.a.7 require that diesel generator air start receivers to be greater than or equal to 240 psig when the associated DG is required to be Operable.
SSES ITS SR 3.8.3.3 maintains tlte same requirement but incorporates a Note for the SR which states that when the associated DG is running the SR does not have to be met.
This is necessary because during and after a DG start, before the standby air compressors can restore air pressure, the air receiver pressure will be reduced such that the SR is no longer met. During this period, even though the DG is running and the DG air starting system has performed its safety function, the DG is inoperable. The note provides an allowance for the DG to be considered Operable if the DG is running. This change is acceptable because once the DG is running the safety function of the DG air start system has been completed. Therefore, this less restrictive change will have no impact on safety.

This change is a less restrictive administrative change with no impact on the margin of safety.
LA.2 SSES CTS 4.8.2.1.f requires an annual performance discharge test of battery capacity for any battery that show signs of degradaticn or has reached 85% of the service life expected for the application. SSES CTS 4.8.2.1.f also defines when degradation is indicated. SSES ITS SR 3.8.4.8 requires an annual performance discharge test. but does not define "a degraded condition." This is acceptable because the specification of the condition when the battery has degraded does not impact the requirement to perform the performance test on an increased frequency. This definition can be adequately controlled in the SSES ITS Bases which requires change control in accordance with SSES ITS 5.5. 10. Bases Control Program. This approach provides an effective level of regulatory control and provides for a more appropriate change control process. The level of safety of facility operation is unaffected by the change because there is no change in the requirement to perform the performance discharge test. Furthermore. NRC and PP5L resources associated with processing license amendments to this design information will be reduced. This change is a less restrictive administrative change with no impact on safety.

In this event, a Frequency less restrictive than the 12 month Frequency is justified. The 24 month Frequency is consistent with the BWR STS. NUREG-1433. Revision 1. SSES CTS 4.8.2.1.f is required to be performed every 12 months when a battery shows degradation or has reached 85K of expected life with capacity <

The purpose of these tests is to ensure the availability of necessary power to ESF systems from Class 1E battery sources. Two division of batteries are required for the mitigation of an accident during conditions in the event of a loss of all offsite power and a worst case single failure. Extending the surveillance interval for these Surveillances is acceptable for the following reasons: the design, in conjunctions with Technical Specification requirements which limit the extent and durations of inoperable OC sources, provides substantial redundancy in OC sources; battery parameters such as float voltage (which verifies battery charger Operability). electro]yte level. and specific gravity are monitored during the dperating cycle to verify battery Operability and will provide prompt identification of any substantial battery degradation or failure: batteries are not discharged except for the performance of the operating cycle test demonstrations of Operability, so there is minimal risk related degradation: battery attributes subject to degradation due to aging such as terminal corrosion and cell deterioration are monitored during the operating cycle. Therefore, any substantial degradation of the will be evident prior to the scheduled performance of these tests.
Based on the above discussion, the impact. if any. from the surveillance test frequency increase on system availability will be small.
A review of the survei llance test history for each of these Surveillance requirements was performed to validate the above conclusion. This historical review of the surveillance test history demonstrates that there are no failures that would invalidate the conclusion that the impact of this change. if any.

A.2 SSES CTS 3.8.2.2 LCO, footnote" ', and Action c recognize the SSES design capability to align some, but not all, 125 VDC Unit 1 and common loads from either a Unit 1 or a corresponding Unit 2 source. However, Unit 1 SSES CTS 3.8.2.2, Action d, prevents a Unit 2 source from powering the Unit 1 and common loads for more than 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br /> after the Unit 1 source is restored to Operable status. This restriction ensures each unit's loads are fed from the corresponding unit's battery.
The FSAR analysis states that the batteries shall not be shared between the units (i.e., Unit 1 loads shall not be powered from the Unit 2 battery).
SSES ITS maintains the same requirements and allowances through different LCOs. First, Unit 1 SSES ITS LCOs only require Unit 1 sources to be Operable.
This is acceptable because, just as in the GTS, only Unit 1 sources are required for Unit 1 operation and any failure of a Unit 1 source will require appropriate Unit 1 Required Actions. For Unit 2, as required in SSES GTS, some Unit 1 sources and distribution systems are required therefore, they are specified in SSES Unit 2 ITS.
This ensures that all required loads for Unit 2 are powered from the appropriate source. To provide the same flexibilityprovided in the SSES ITS, Unit 2 SSES 1TS LCOs 3.8.4, 3.8.5, 3.8.7 and 3.8.8 provide Conditions and Required Actions which allow the transfer of Unit 1 and common loads to Unit 2 sources and distribution systems. Furthermore, SSES Unit 2 ITS SR 3.8.7.1 and SSES Unit 2 ITS SR 3.8.8.1 include verification that the Unit 1 and common loads are powered from a Unit 1 source. Based on the above discussions, the requirements in SSES CTS are consistent'with the SSES'ITS and therefore the changes are administrative witn no impact on safety.

- H T V SSES CTS Table 4.8.2.1-1 footnote (c) allowance to correct the Category 8 float voltage limit for temperature has been deleted in SSES ITS Table 3.8.6-1. The deletion is consistent with the recorrmrendations of IEEE-450. . The change reflects the current requirements for battery esting and therefore. this more restrictive change will have no n ative impact on safety.
i "~c, 8~~~/,
SSES CTS Table 4.8.2.1-1 footnote (1) and footnote (2) allow deviation from the Category A and 8 limits provided parameters are restored. SSES ITS Action A requires the restoration of battery limits and adds Required Action A.l for when a Category A or 8 limit is not met. This Required Action requires a check within 1 hour1.157407e-5 days <br />2.777778e-4 hours <br />1.653439e-6 weeks <br />3.805e-7 months <br /> that the pilot cell electrolyte level and float voltage are within the Category C limits (SSES CTS Table 4.8.2.1-1 Category 8 allowable values). This ensures that if the pilot cell is below Category C limits. the battery will be declared inoperable imediately. Therefore. this more restrictive change has no negative impact on safety.
H.3 SSES CTS 4.8.2.1.b.1. the quarterly verification of specific gravity and voltage against Category 8 limits. includes a requirement that battery must be demonstrated to meet Category 8 limits within 7 days of a significant battery discharge. SSES ITS SR 3.8.6.2 requires the same verification within 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> of a signtficant battery discharge. This change is needed because confirmation of battery Operability following a significant discharge must be made promptly and 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> allows sufficient time to plant for an unscheduled Surveillance'nd complete the performance of the surveillance of cell parameters without excessive haste. Since this confirmation of Operability is revised to make the determination sooner. the change has no negative impact on safety.
T H SSES CTS Table 4.8.2.1-1 footnote (b) requires the + 24 volt batteries and associated,chargers to be Operable. These batteries and chargers provide power to the intermediate range monitor (IRH) and the source range monitor (SRH) instrumentation. They are a support system for the IRH and SRH instrumentation. SSES ITS 3.3.1.2. require the Operability of the SRHs, and SSES ITS 3.3.1.1. requires the Operability of the IRHs. SSES ITS does not specifically require the Operability of the + 24 voltofbatteries and associated chargers. but the SSES ITS definition Operable-Operability requires that all normal or emergency electrical power is also capable of performirg ;t s related support function. The elimination of the specific requirements for the 24 volt subsystems is acceptable becar.se the requirement to maintain the Operability of the SRHs and I.Hs is maintained and the ensure. 24 volt battery requirements do not i-.act the requirement to the SUSQUEHANNA UNIT 1 AND 2 Revision 0. 07/31/96

SRHs and IRMs are Operable. This approach provides an effective level of regulatory control and provides for a more appropriate change control process. The level of safety of facility operation is unaffected by the change because there is no change in the requirement to maintain the SRHs and IRMs Operable. Furthermore.
NRC and PPKL resources associated with processing license amendments to these Administrative Control requirements will be reduced. This change is a less restrictive administrative change with no impact on the margin of safety.
SSES CTS 4.8.2.l.b.3 requires that the average electrolyte temperature of 10 or 20. as applicable, of connected cells be verified above 60 F. SSES ITS SR 3.8.6.3 require the electrolvte temperature be verified, but does not define the number of cells to be measured. SSES ITS 3.8.6.3 requires a "representative" cells be verified within the limit. This is acceptable because the requirement to verify the temperature is maintained in SSES "I"
ITS and the number of cells verified does not impact this
". Th defines the surveillance requirements for the battery testing. Therefore. the detail relating to the plant specific determination of "representative" is proposed to be relocated to the Bases. Therefore, this information can be adequately defined and controlled in SSES ITS Bases which require change control in accordance with SSES ITS 5.5.10, Bases Control Program. This approach provides an effective level of regulatory control and provides for a more appropriate change control process. The level of safety of facility operation is unaffected by the change because there is no change in the requirement to perform the SR. Furthermore. NRC and PAL resources associated with processing license amendments to these Administrative Control requirements will be reduced. This change is a less restrictive administrative change with no impact on the margin, of safety.
L.l SSES CTS 4.8.2.1.b.3 requires that once every 92 days and within 7 days after a battery discharge. the average electrolyte temperature is verified to be above 60 F. SSES .ITS SR 3.8.6.3 requires this same verification to be performed only once every 92 days. This is acceptable because a large discharge of the battery wi ll tend to heat the battery electrolyte not reduce the temperature. The requirement to Yeasure electrolyte temperature is not necessary. Therefore .nis less restrictive change will have no impact on safety.

This change has been made to ensure that Improved Technical Specifications account for the SSES design.
Therefore, this change does not represent a significant deviation from the intent of NUREG 1433.
NUREG-1433. Revision 1. LCO 3.8.6. Table 3.8.6-1, footnote (b).
requires that specific gravity measurements be corrected for level and temperature except when the battery is on float charge. SSES ITS LCO 3.8.6, Table 3.8.6-1. footnote (b). does not require level correction for soecific gravity regardless of the status of the float charge. This change is needed and acceptable based on the recomnendations of the battery manufacturer and is specifically permitted by IEEE-450 . 1995. Annex A.3. IEEE-450 . 1995 'nnex A.3. states that "if the electrolyte level is between the high ar d low level marks and the temperature corrected specific gravity of the electrolyte is within the manufacturer's specific gravity range, it is not necessary to correct the specific gravity of the battery for electrolyte level. This change has no impact on safety because. as determined by the manufacturer with the concurrence of IEEE 450. battery specific gravities that are not corrected for level provide an adequate indication of the state of the battery. This change has been made to ensure that c'harge Improved Technical Specifications account for the SSES design.
Therefore. this change does not represent a significant deviatior from the intent of NUREG 1433.

With one or more Unit 1 DC buses inoperable. the remaining OC electrical power distribution subsystems may be capable of supporting the minimum safety functions necessary to shut down the reactor and maintain it in a safe shutdown condition. assuming no single failure. The. overall reliability is reduced. however. because a single failur e in one of the remaining DC electrical power distribution subsystems could result in the minimum required ESF functions not being supported. Therefore. the required OC buses must be restored to OPERABLE status within 2 hours2.314815e-5 days <br />5.555556e-4 hours <br />3.306878e-6 weeks <br />7.61e-7 months <br /> by powering the bus from the associated batter or c r er.

Condition B represents one subsystemwit out adequate OC power. potentially with both the battery significantly degraded and the associated charger non-functioning. In this situation the plant is significantly more vulnerable to a loss of minimally required OC power. It is. therefore.
imperative that the operator's attention focus on stabilizing the plant. minimizing the potential for loss of power to the remaining divisions. and restoring power to ti e affected division.
This 2 hour2.314815e-5 days <br />5.555556e-4 hours <br />3.306878e-6 weeks <br />7.61e-7 months <br /> limit is more conservative than Completion Times allowed for the majority of components that would be without .

The second Completion Time for Required Action B.l establishes a limit on the maximum time allowed for any combination of required distribution subsystems to be inoperable during any single continuous occurrence of failing to meet hours the LCO. If Condition C is entered while.
for instance. an AC bus is inoperable and subsequently restored OPERABLE, the LCO may already have been not met for up to 8 hours9.259259e-5 days <br />0.00222 hours <br />1.322751e-5 weeks <br />3.044e-6 months <br />. This situation could lead to a total duration of 10 . since initial failure of the LCO. to restore the OC distribution system. At this time, an AC division could again become inoperable. and OC distribution could be restored OPERABLE. This could continue indefini ly.
C dition is modified by a Note that states that Condition is not pplicable to the DG E DC electrical power subsystem. Condition 0 or E is applicable to an inoperable OG E DC electrical power subsystem.
.This Completion Time allows for an exception to the normal "time zero" for beginning the allowed outage time "clock."
This allowance results in establishing the "time zero" at the time the LCO was initially not met, instead of at the time Condition C was entered. The 16 hour1.851852e-4 days <br />0.00444 hours <br />2.645503e-5 weeks <br />6.088e-6 months <br /> Completion Time is an acceptable limitation on this potential of failing to meet the LCO indefinitely.

This clariQcation is necessary because defaulting to LCO 3.0.3 (during irradiated fuel assembly movement in MODES 1, 2, or 3) would require the reactor to be shutdown, but would not require immediate suspension of movement of irradiated fuel assemblies when required components are inoperable. LCO 3.0.3 is only applicable in MODES 1, 2, or 3.
Therefore, once the unit has been placed in MODE 4 in accordance with LCO 3.0.3, LCO 3.03 is no longer applicable: The actions of the "shutdown" Electrical Power System Technical SpeciQcations, which require suspension of irradiated fuel movement, would then be applicable. However, the requirements of LCO 3.0.3 would allow up to 37 hours4.282407e-4 days <br />0.0103 hours <br />6.117725e-5 weeks <br />1.40785e-5 months <br /> to place the unit in MODE 4 (and, as a result, up to 37 hours4.282407e-4 days <br />0.0103 hours <br />6.117725e-5 weeks <br />1.40785e-5 months <br /> to suspend movement of irradiated fuel). Therefore, with the unit in this Condition, the Note (LCO 3.0.3 is not applicable) ensures that the actions for requiring immediate suspension of irradiated tuel movement are not postponed due to entry into LCO 3.0.3, and that the unit is immediately placed in a condition of minimum risk with respect to fuel handling in MODES 1,2, or 3.

The option to transfer required comnon loads to an OPERABLE Unit 2 electrical power subsystem ensures power will be restored to required loads. To ensure any loads Mich are not transferred to the Unit 2 power distribution subsystem are compensated for, Required Action A.3.2, requires the required features to be declared inoperable. Although the corresponding Unit 2 electrical power subsystem is evaluated for this condition, this violates a design coaeitment to maintain power separation between units. To minimize the time this condition exists, Required Action A.3.3 directs that power supply be restored to the corresponding Unit 1 electrical power subsystem, which restores power to the comaon loads, or requires that the Unit 1 and coaaen loads are declared inoperable. The Completion Time of 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br /> provides sufficient tiaa to restore power and acknowledges the fact that the condition, although not consistent with design requirements, maintains all required safety systems available.
