The JFD for deletion of this iSTS LCO states, in part, the following:"The bracketed items specified in ISTS LCO 3.8.1.c and ISTS 3.8.1 ACTION F have been deleted since the Kewaunee design does not include automatic load sequencers." The iSTS "REVIEWER'S NOTE" for this LCO (3.8.1.c) states the following:"This Condition may be deleted if the unit design is such th at any sequencer failure mode will only affect the ability of the associated DG to power its respective safety loads following a loss of offsite power i ndependent of, or coincident with, a Design Basis Event." Elsewhere in the document, including ISTS SR 3.8.1.11 (ITS SR 3.8.1.12), ISTS SR 3.8.1.19 (ITS SR 3.8.1.16) and the proposed ITS Bases, the phrase "automatic load sequencers" have been revised to reflect the KPS use of "time delay relays."

1 ACTION F provides the actions if one of the two sequencers is inoperable, and allows 12 hours1.388889e-4 days 0.00333 hours 1.984127e-5 weeks 4.566e-6 months to restore the sequencer to OPERABLE st atus. This 12 hour1.388889e-4 days 0.00333 hours 1.984127e-5 weeks 4.566e-6 months Completion Time is the same as the time allowed for one offsite circuit and one DG inoperable concurrently as shown in IS TS ACTION D (Page 25). As stated in the Reviewer's Note, the Conditi on may be deleted if the load sequencer only affects the DG, i.e., it does not affect the offsite circuit. Furthermore, the ISTS Bases for ACTION F (Page 54) states that the sequencer is an essential support system to both the DG and offsite circuit, and that it affects every major ESF System in the Division.

The KPS design does not include load sequencers of this design. Each major ESF component has individual time delay relays that operate individual components, not all ESF components.

Thus, if a single time delay relay fails, only the individual component and the DG could be affected. The ITS Bases describes this in the Background section, first paragraph (Page 44). The ITS Bases states that when the DG is tied to the ESF bus, loads are then sequentially connected to its respective ESF bus by individual time delay relays.

Thus, as l ong as enough air is in each required air start receiver bank to start the DG one time, the pressure is acceptable. KPS has maintained th is requirement in the ITS. The SR 3.8.3.4 pressure ensures that the DG can be started at least one time." The KPS USAR states, in part, that the primary or reserve air storage tanks have sufficient storage to crank the DG for twenty seconds. Additionally, the start cycle described in th e KPS USAR states that the DG may continue to crank for up to 15 seconds prior to a start failure fault lockout. The proposed KPS ITS 3.8.3 deletes ISTS Co ndition 3.8.3.E (m inimum air start receiver pressure) and proposes a ne w Condition 3.8.3.E without a minimum air start receiver bank pressure. Bases on the above, explain why the minimum value (> 200 psig) for air start recei ver bank pressure is not a required condition for TS 3.8.3.

Each train of the D/G Startup Air System consists of one air compressor, a primary bank consisting of two air receivers, an d a reserve bank consisting of two air receivers. The primary and re serve bank inlet piping is separated by two inlet check valves, one for each bank. Th e primary and reserve bank outl et piping is separated by one discharge check valve for the primary bank and one closed manual discharge valve for the reserve bank. Also, each primary and reserve bank has a normally closed, manual cross-connect valve. The cross-connect valves provide the ability to cross-connect the primary and reserve banks of an air system train. The cross-connect valves also provide the ability to cross-connect the bank(s) of one air system train to the bank(s) of the other air system train.

Normal alignment has the primary bank s upplying the startup ai r to its associated D/G with the reserve bank isolated for supplying startup air to the D/G. However, the reserve bank air pressure is maintained by the air compre ssor through the inlet check valve. Cross-connect valves for the primary and reserve banks are closed.

When cross-connecting the OPERABLE D/G Startup Air System with the INOPERABLE D/G Startup Air System, the reserve bank on the OPERABLE ai r system would be aligned to the INOPERABLE air system.

The OPERABLE air system's primary bank inlet check valve, pr imary bank closed manual cross-connect valve, and reserve bank closed manual outlet valve maintain train independence from the INOPERABLE air system during the time the OPERABLE air system reserve bank cro ss-connect valve is open. Al so, the dedicated operator provides control for maintaining the air pressure in the re serve bank of the OPERABLE air system.

p h p?re q uestT ype=areaItemPrint&itemId=2771 DISCUSSION OF CHANGES ITS 3.8.3, DIESEL FUEL OIL, LUBE OIL AND STARTING AIR change is designated as less restrictive since less stringent Required Actions are being applied in the ITS than were applied in the CTS.

L02 (Category 7 - Relaxation of Surveillance Frequency)

CTS Table TS 4.1-3 Equipment Test 9 requires the diesel fuel oil inventory to be verified within limits weekly (every 7 days). ITS SR 3.8.3.1 requires the verification to be performed every 31 days. This changes the CTS by extending the Surveillance interval from 7 days to 31 days.

The purpose of the Surveillance is to verify that there is sufficient diesel fuel oil to operate the associated DG for 7 days. The change is acceptable since the DG is normally only required to be run every 31 days. Therefore, the 31 day check of the diesel fuel oil level is sufficient. Furthermore, a low level alarm is provided and the operators would be aware of any large use of diesel fuel oil during this period. This change is designated as less restrictive because a Surveillance will be performed less frequently under the ITS than under the CTS.

L03 (Category 4 - Relaxation of Required Action) CTS 3.7.a.7 requires the DGs to be OPERABLE. However, no explicit requirements are specified in the CTS for the DG Starting Air Systems. Thus, if a DG Starting Air System is inoperable, the associated DG would be inoperable and the associated actions of CTS 3.7.b would be taken. ITS LCO 3.8.3, in part, requires the Starting Air System for each DG to be OPERABLE. This is discussed in DOC A05. ITS 3.8.3 ACTION E provides the actions when a DG air compressor is inoperable and ITS 3.8.3 ACTION F provides the actions if the requirements of ACTION E are not met or if the required air receiver bank for one or more DGs is not within limits. This changes the CTS by adding specific actions for when a DG Starting Air System is inoperable.

The purpose of the air receiver bank pressure requirement is to ensure adequate starting air is available for OPERABILITY of the DGs. For KPS, the DGs are also dependent upon air for operation of the DG room ventilation system. This dependency for operation requires a sufficient volume of air at a pressure greater than 13 psig for operation. Under normal operations, the emergency powered air compressors maintain the air receiver banks, from which the operating air is also provided, pressurized (220-240 psig).

The Kewaunee design consists of two primary air receiver banks normally aligned (one for each DG) and two reserv e air receiver banks normally isolated (one for each DG). Each air receiver bank includes two air receivers. The KPS design allows the primary air receiver bank and its associated reserve air receiver bank to be in service simultaneously. In the event of an air compressor failure or required maintenance on the air compressor, both air receiver banks (primary and reserve) can be placed in service and the opposite DGs air compressor is available to recharge the air receiver banks to the normal band (i.e., a cross-tie between the DG Starting Air Systems is provided).

KPS has performed an analysis for an operating condition where a start demand for a DG occurs with both the primary and reserve air receiver banks in service and at a pressure of 197 psig (which accounts for 200 psig low pressure alarm and instrument tolerances), and analyzes for or includes assumptions for:

Kewaunee Power Station Page 6 of 7 DISCUSSION OF CHANGES ITS 3.8.3, DIESEL FUEL OIL, LUBE OIL AND STARTING AIR Kewaunee Power Station Page 7 of 7 The mass of air consumed by a six second start (i.e., worse case start and meet accident response time), from a reduced air receiver banks pressure of 197 psig. The assumed 197 psig pressure accounts for a low air receiver bank pressure alarm at 200 psig, and accounts for instrument tolerances.

The mass of air consumed during ventilation damper operations.

The mass of air consumed in the tubing which supports the ventilation damper operations.

Leakage within the Starting Air System while in the alignment described above (primary and reserve air receiver banks in service).

With these conservative assumptions, the analysis demonstrates that the combined capacity of the primary and reserve air receiver banks supply greater than 48 hours5.555556e-4 days 0.0133 hours 7.936508e-5 weeks 1.8264e-5 months of operating air for the associated DG. While the capability exists to cross-tie the air receiver banks of one DG to the other, this is not assumed in the analysis.

The proposed ITS 3.8.3 ACTION E will ensure the two primary assumptions of the analysis are met. When one air compressor is inoperable, ITS 3.8.3 Required Action E.1 requires the two air receiver banks (primary and reserve) to be aligned to the associated DG (i.e., both placed in service) within 1 hour1.157407e-5 days 2.777778e-4 hours 1.653439e-6 weeks 3.805e-7 months . ITS 3.8.3 Required Action E.2 will require the pressure in the in-service air receiver banks to be

> 200 psig. Also, the Note to the Required Action will allow the other DG's Starting Air System to be intermittently cross-tied to the inoperable DG's Starting Air System to maintain this pressure. If these two requirements are met, ITS 3.8.3 Required Action E.3 will allow 48 hours5.555556e-4 days 0.0133 hours 7.936508e-5 weeks 1.8264e-5 months to restore the inoperable air compressor to OPERABLE status. During this 48 hour5.555556e-4 days 0.0133 hours 7.936508e-5 weeks 1.8264e-5 months period, ITS 3.8.3 Required Actions E.1 and E.2 are required to be met. If either one of these Required Actions (Required Action E.1 or E.2) are not met, then ITS 3.8.3 ACTION F will require the associated DG to be immediately declared inoperable.

This ensures that, at all times during the 48 hour5.555556e-4 days 0.0133 hours 7.936508e-5 weeks 1.8264e-5 months restoration time, the DG has sufficient air in the air receiver banks to start and operate for 48 hours5.555556e-4 days 0.0133 hours 7.936508e-5 weeks 1.8264e-5 months . In addition, if the other DGs air compressor becomes inoperable during this time, ITS 3.8.3 ACTION F would require both DGs to be immediately declared inoperable. Thus, the proposed ACTIONS E and F only allow one air compressor to be inoperable at a time.

Periodic testing is also conducted to ensure the leakage of the system assumed in the analysis continues to be valid. The ITS also includes routine testing of the air compressors and the required air receiver banks, as discussed in DOC M03.

These changes are designated as less restrictive because a new allowance is included in the Technical Specifications to allow one DG's Starting Air System air compressor to be inoperable for up to 48 hours5.555556e-4 days 0.0133 hours 7.936508e-5 weeks 1.8264e-5 months prior to declaring the associated DG inoperable.

However, as long as both air receiver banks (primary and reserve) for the associated DG are in service and the air pressure in the two air receiver banks is > 200 psig, there is adequate capacity for at least one start and the DG can be operated for at least 48 hours5.555556e-4 days 0.0133 hours 7.936508e-5 weeks 1.8264e-5 months after the start. Therefore, the DG can be considered OPERABLE. These compensatory actions (Required Actions E.1 and E.2) must be met within 1 hour1.157407e-5 days 2.777778e-4 hours 1.653439e-6 weeks 3.805e-7 months . Provided the compensatory measures are met, a period of 48 hours5.555556e-4 days 0.0133 hours 7.936508e-5 weeks 1.8264e-5 months is allowed to restore the air compressor to OPERABLE status. If at any time during the 48 hours5.555556e-4 days 0.0133 hours 7.936508e-5 weeks 1.8264e-5 months Required Action E.1 or E.2 is not met, ACTION F must be entered. The 48 hours5.555556e-4 days 0.0133 hours 7.936508e-5 weeks 1.8264e-5 months is acceptable based on an analysis that shows that with both air receiver banks in service and at a pressure of 200 psig, sufficient air remains to start the DG and operate it for at least 48 hours5.555556e-4 days 0.0133 hours 7.936508e-5 weeks 1.8264e-5 months . In addition, the capability exists to cross

-tie the other DG's Starting Air System and recharge the inoperable air compressor

's associated air receiver banks. Furthermore, the probability of an event requiring operation of the DGs during this period is low.

Required Action E.2 is modified by a Note that allows the cross

-tie between the DG Starting Air Systems to be intermittently opened under administrative control to achieve and maintain the inoperable Starting Air System air receiver banks within the pressure limit of the Required Action. These administrative controls consist of stationing a dedicated operator at the DG Starting Air System cross

-connect valve for the OPERABLE DG, who is in continuous communication with the control room. In this way, the OPERABLE Starting Air System can be isolated from the inoperable Starting Air System if a need for isolation is indicated. Furthermore, for the OPERABLE DG, only the cross-connect valve for the isolated air receiver bank should be opened. The time the cross-connect valves are opened should be minimized.

This changes the CTS by removing a potential conflict between two CTS statements.

This change is acceptable because the potential conflict within the CTS would be resolved by applying the requirements of CTS 4.0.a. CTS 4.0.a requires

surveillance requirements to be met duri ng the operational MODES specified in the LCO. The diesel fuel oil system is a support system for each DG. The CTS and ITS maintain this relationship between the DGs and the diesel fuel oil system without any changes in the technical requirements. This change is designated as administrative because it does not result in a technical change to the CTS.

A05 CTS 3.7.a.7 requires the DGs to be OPERABLE. However, no specific requirements are specified in the CTS for the DG Starting Air Systems. ITS LCO 3.8.3, in part, requires the Starting Air System for each DG to be OPERABLE. The Applicability for this requirement is when the associated DG is required to be

OPERABLE. This changes the CTS by explicitly stating that the Starting Air System for each DG is required to be OPERABLE.

The purpose of the Starting Air System is to support OPERABILITY of the associated DG. The air receiver banks are required to be within the pressure limit to provide the necessary starting air to crank the DG when required. The air compressors are required to ensure air is available in the air receiver banks to operate certain ventilation dampers in the DG rooms. These ventilation dampers ensure the DG room air temperature is maintained such that the DG can perform its required function during the accident. Currently, the CTS definition of

OPERABLE, as it is applied to the DGs, requires the air receiver bank pressure to be within limit and the air compressor to be capable of automatically recharging the associated air receiver bank. Therefore, the addition of this specific LCO statement is acceptable and is designated as administrative since it does not result in a technical change to the CTS. The specific Surveillance Requirements and ACTIONS to take when the Starting Air System is inoperable is discussed in DOCs M03 and L03.

MORE RESTRICTIVE CHANGES

M01 CTS 3.7.a requires the diesel generators (specified in CTS 3.7.a.7), and hence, the combined underground storage tank and corresponding day tanks level to be within the limits and be tested in accordance with Table TS 4.1-3 Equipment Test 9 when the reactor is critical. ITS LCO 3.8.3 requires the stored diesel fuel oil to

be within limits "when associated DG is required to be OPERABLE." ITS 3.8.1 requires both DGs to be OPERABLE in MODES 1, 2, 3, and 4 and ITS 3.8.2

requires one of the DGs to be OPERABLE in MODES 5 and 6 and during movement of irradiated fuel assemblies. This changes the CTS by adding requirements specifying the stored diesel fuel oil limit to be met for both DGs in MODES 3 and 4 and in MODE 2 when the reactor is not critical and for one DG in MODES 5 and 6 and during movement of irradiated fuel assemblies.

The purpose of CTS 3.7.a, in part, is to ensure the DGs are OPERABLE to mitigate the consequences of a transient or design basis accident. In ITS, the DGs are required to be OPERABLE in MODES 1, 2, 3, and 4 when an accident A ttachment 1, Volume 13, Rev. 0, Page 108 of 289 A ttachment 1, Volume 13, Rev. 0, Page 108 of 289 Enclosure (1 of 4), Q&A to Attachment 1, Volume 13 (Section 3.8) Page 24 of 41 Enclosure (1 of 4), Q&A to Attachment 1, Volume 13 (Section 3.8) Page 24 of 41 A ND Header fix is to all DOC Pages DISCUSSION OF CHANGES ITS 3.8.3, DIESEL FUEL OIL, LUBE OIL AND STARTING AIR within limits. This restoration may involve feed and bleed procedures, filtering, or combinations of these procedures. Even if a DG start and load was required during this time interval and the stored fuel oil properties were outside limits, there is a high likelihood that the DG would still be capable of performing its intended function.

The purpose of the lube oil inventory requirement in ITS LCO 3.8.3 and SR 3.8.3.2 is to ensure a 7 day lube oil inventory for each DG is maintained. The proposed ITwill ensure the 7 day inventory requirement is met, based upon vendor recommendations. In addition, ITS 3.8.3 ACTION B will allow the 7 day limit to not be met for each DG for up to 48 hours5.555556e-4 days 0.0133 hours 7.936508e-5 weeks 1.8264e-5 months provided sufficient lube oil inventory is available for 6 days. If the lube oil inventory is not restored within 48 hours5.555556e-4 days 0.0133 hours 7.936508e-5 weeks 1.8264e-5 months , or if the 6 day limit is not met, then the associated DG is required to be declared inoperable immediately. Furthermore, as stated in the ITS 3.8.3 ACTIONS Note, ITS 3.8.3 ACTION B is allowed to be separately entered for each DG. Therefore, this change is acceptable.

These changes are designated as more restrictive because explicit requirements are included in the Technical Specifications for stored diesel fuel oil total particulates, new diesel fuel oil properties and lube oil inventory limits.

M03 The CTS does not provide any specific testing requirements to check the DG air receiver banks or to verify proper operation of the DG starting air compressors. ITS SR 3.8.3.4 and SR 3.8.3.5 require these verifications every 31 days. The CTS also does not provide any specific testing requirements to check for or remove accumulated water from the fuel oil storage tanks. ITS SR 3.8.3.6 requires this verification every 92 days. This changes the CTS by requiring new Surveillance Requirements to ensure the Starting Air System is OPERABLE and to check for and remove accumulated water from the fuel oil storage tanks.

The purpose of ITS SR 3.8.3.4 and SR 3.8.3.5 is to ensure the Starting Air

System for each DG is Operable. SR 3.8.3.4 ensures adequate air pressure in

the required air start receiver bank to start the DG one time. SR 3.8.3.5 ensures each DG air compressor can operate automatically to recharge the required air start receiver bank. This change is acceptable because the SRs provide

additional assurance that the Starting Air System for each DG can perform its

required function The purpose of ITS SR 3.8.3.6 is to ensure that an environment conducive to microbiological fouling does not exist. This change is acceptable because it provides additional assurance that accumulated water is removed on a regular

basis to ensure an environment conducive to microbiological fouling does not exist in the fuel oil storage tanks.

These changes are designated as more restrictive because explicit Surveillance Requirements have been added to the CTS.

LESS RESTRICTIVE CHANGES

L01 (Category 4 - Relaxation of Required Action)

CTS 3.7.a.7 does not provide explicit compensatory actions if the volume of fuel oil in a storage tank and corresponding day tanks is less than the specified limit. Thus, if the minimum required volume is not met, the associated DG must be declared inoperable and CTS 3.7.b.7 must be entered. ITS 3.8.3 ACTION A allows the unit to not declare the associated DG inoperable as long as the usable volume of stored fuel oil is greater than a six day limit (i.e., > 27,961 gallons). In this situation, ITS 3.8.3 Required Action A.1 allows 48 hours5.555556e-4 days 0.0133 hours 7.936508e-5 weeks 1.8264e-5 months to restore the fuel oil volume to within limits. As stated in the ACTIONS Note, a separate entry into this new ACTION is allowed for each DG. If this Required Action and associated Completion Time are not met or if the fuel oil storage tank usable volume is < 27,961 gallons, the associated DG must be declared inoperable immediately (ITS 3.8.3 ACTION F).

This changes the CTS by allowing the DGs to not be declared inoperable with the fuel oil storage tank and corresponding day tanks volume not within the specified Surveillance limit as long as the associated DG has enough fuel oil for 6 days of operation at rated load.

The purpose of ITS 3.8.3 ACTION A is to allow time to restore the stored diesel fuel oil volume to within the specified limit for a given DG. This change is acceptable because the Required Actions are used to establish remedial measures that must be taken in response to a degraded condition in order to

minimize risk associated with continued operation while providing time to restore inventory. The Required Actions are consistent with safe operation under the specified Condition, considering the OPERABLE status of the redundant systems or features. This includes the capacity and capability of remaining systems or features, reasonable time for repairs or replacement, and the low probability of a DBA occurring during the repair period. The addition of ITS 3.8.3 ACTION A will allow each DG to not be declared inoperable with the associated stored diesel fuel oil volume not within the specified Surveillance limit as long as the DG has enough fuel oil for 6 days of operation at rated load. In this Condition, the 7 day fuel oil supply for the DG is not available. However, the Condition is restricted to fuel oil volume reductions that maintain at least a 6 day supply. These

circumstances may be caused by events such as full load operation required after an inadvertent start while at minimum required fuel oil level, or feed and bleed operations, which may be necessary due to increasing particulate levels or any number of other oil quality degradations. This restriction allows sufficient time for obtaining the requisite replacement volume and performing the analyses required prior to addition of fuel oil to the tank. A period of 48 hours5.555556e-4 days 0.0133 hours 7.936508e-5 weeks 1.8264e-5 months is considered sufficient to complete restoration of the required volume prior to

declaring the associated DG inoperable. This period is acceptable based on the remaining capacity (> 6 days), the fact that procedures will be initiated to obtain replenishment, and the low probability of an event during this brief period. This Kewaunee Power Station Page 5 of 7 A ttachment 1, Volume 13, Rev. 0, Page 111 of 289 A ttachment 1, Volume 13, Rev. 0, Page 111 of 289 Enclosure (1 of 4), Q&A to Attachment 1, Volume 13 (Section 3.8) Page 26 of 41 Enclosure (1 of 4), Q&A to Attachment 1, Volume 13 (Section 3.8) Page 26 of 41 E

DISCUSSION OF CHANGES ITS 3.8.3, DIESEL FUEL OIL, LUBE OIL AND STARTING AIR change is designated as less restrictive since less stringent Required Actions are being applied in the ITS than were applied in the CTS.

L02 (Category 7 - Relaxation of Surveillance Frequency)

CTS Table TS 4.1-3 Equipment Test 9 requires the diesel fuel oil inventory to be verified within limits weekly (every 7 days). ITS SR 3.8.3.1 requires the verification to be performed every 31 days. This changes the CTS by extending the Surveillance interval from 7 days to 31 days.

The purpose of the Surveillance is to verify that there is sufficient diesel fuel oil to operate the associated DG for 7 days. The change is acceptable since the DG is normally only required to be run every 31 days. Therefore, the 31 day check of the diesel fuel oil level is sufficient. Furthermore, a low level alarm is provided and the operators would be aware of any large use of diesel fuel oil during this

period. This change is designated as less restrictive because a Surveillance will

be performed less frequently under the ITS than under the CTS.

L03 (Category 4 - Relaxation of Required Action) CTS 3.7.a.7 requires the DGs to be OPERABLE. However, no explicit requirements are specified in the CTS for

the DG Starting Air Systems. Thus, if a DG Starting Air System is inoperable, the associated DG would be inoperable and the associated actions of CTS 3.7.b

would be taken. ITS LCO 3.8.3, in part, requires the Starting Air System for each DG to be OPERABLE. This is discussed in DOC A05. ITS 3.8.3 ACTION E provides the actions when a DG air compressor is inoperable and ITS 3.8.3 ACTION F provides the actions if the requirements of ACTION E are not met or if

the required air receiver bank for one or more DGs is not within limits. This changes the CTS by adding specific actions for when a DG Starting Air System is inoperable.

The purpose of the air receiver bank pressure requirement is to ensure adequate starting air is available for OPERABILITY of the DGs. For KPS, the DGs are also dependent upon air for operation of the DG room ventilation system. This dependency for operation requires a sufficient volume of air at a pressure greater than 13 psig for operation. Under normal operations, the emergency powered air compressors maintain the air receiver banks, from which the operating air is also provided, pressurized (220-240 psig).

The Kewaunee design consists of two primary air receiver banks normally aligned (one for each DG) and two reserve air receiver banks normally isolated (one for each DG). Each air receiver bank includes two air receivers. The KPS design allows the primary air receiver bank and its associated reserve air

receiver bank to be in service simultaneously. In the event of an air compressor failure or required maintenance on the air compressor, both air receiver banks (primary and reserve) can be placed in service and the opposite DGs air compressor is available to recharge the air receiver banks to the normal band (i.e., a cross-tie between the DG Starting Air Systems is provided).

KPS has performed an analysis for an operating condition where a start demand for a DG occurs with both the primary and reserve air receiver banks in service and at a pressure of 197 psig (which accounts for 200 psig low pressure alarm and instrument tolerances), and analyzes for or includes assumptions for: Kewaunee Power Station Page 6 of 7 A ttachment 1, Volume 13, Rev. 0, Page 112 of 289 A ttachment 1, Volume 13, Rev. 0, Page 112 of 289 Enclosure (1 of 4), Q&A to Attachment 1, Volume 13 (Section 3.8) Page 27 of 41 Enclosure (1 of 4), Q&A to Attachment 1, Volume 13 (Section 3.8) Page 27 of 41 DISCUSSION OF CHANGES ITS 3.8.3, DIESEL FUEL OIL, LUBE OIL AND STARTING AIR Kewaunee Power Station Page 7 of 7 The mass of air consumed by a six second start (i.e., worse case start and meet accident response time), from a reduced air receiver banks pressure of 197 psig. The assumed 197 psig pressure accounts for a low air receiver bank pressure alarm at 200 psig, and accounts for instrument tolerances.

The mass of air consumed during ventilation damper operations.

The mass of air consumed in the tubing which supports the ventilation damper operations.

Leakage within the Starting Air System while in the alignment described above (primary and reserve air receiver banks in service).

With these conservative assumptions, the analysis demonstrates that the combined capacity of the primary and reserve air receiver banks supply greater than 48 hours5.555556e-4 days 0.0133 hours 7.936508e-5 weeks 1.8264e-5 months of operating air for the associated DG. While the capability exists to cross-tie the air receiver banks of one DG to the other, this is not assumed in the analysis.

The proposed ITS 3.8.3 ACTION E will ensure the two primary assumptions of the analysis are met. When one air compressor is inoperable, ITS 3.8.3 Required Action E.1 requires the two air receiver banks (primary and reserve) to be aligned to the associated DG (i.e., both placed in service) within 1 hour1.157407e-5 days 2.777778e-4 hours 1.653439e-6 weeks 3.805e-7 months . ITS 3.8.3 Required Action E.2 will require the pressure in the in-service air receiver banks to be > 200 psig. Also, the Note to the Required Action will allow the other DG's Starting Air System to be intermittently cross-tied to the inoperable DG's Starting Air System to maintain this pressure. If these two requirements are met, ITS 3.8.3 Required Action E.3 will allow 48 hours5.555556e-4 days 0.0133 hours 7.936508e-5 weeks 1.8264e-5 months to restore the inoperable air compressor to OPERABLE status. During this 48 hour5.555556e-4 days 0.0133 hours 7.936508e-5 weeks 1.8264e-5 months period, ITS 3.8.3 Required Actions E.1 and E.2 are required to be met. If either one of these Required Actions (Required Action E.1 or E.2) are not met, then ITS 3.8.3 ACTION F will require the associated DG to be immediately declared inoperable.

This ensures that, at all times during the 48 hour5.555556e-4 days 0.0133 hours 7.936508e-5 weeks 1.8264e-5 months restoration time, the DG has sufficient air in the air receiver banks to start and operate for 48 hours5.555556e-4 days 0.0133 hours 7.936508e-5 weeks 1.8264e-5 months . In addition, if the other DGs air compressor becomes inoperable during this time, ITS 3.8.3 ACTION F would require both DGs to be immediately declared inoperable. Thus, the proposed ACTIONS E and F only allow one air compressor to be inoperable at a time.

Periodic testing is also conducted to ensure the leakage of the system assumed in the analysis continues to be valid. The ITS also includes routine testing of the air compressors and the required air receiver banks, as discussed in DOC M03.

These changes are designated as less restrictive because a new allowance is included in the Technical Specifications to allow one DG's Starting Air System air compressor to be inoperable for up to 48 hours5.555556e-4 days 0.0133 hours 7.936508e-5 weeks 1.8264e-5 months prior to declaring the associated DG inoperable.

4. ISTS SR 3.8.3.5 requires a check for and removal of accumulated water from each fuel oil storage tank every 31 days, and the 31 day Frequency is bracketed.

This check would normally be performed when the fuel oil storage tank particulate check required by ISTS 5.5.13.c is performed. As described in the JFDs for ITS Section 5.5, this 31 day particulate check has been changed to 92 days in the KPS ITS (ITS 5.5.11.c). Furthermore, Regulatory Guide 1.137 states that a quarterly Frequency is acceptable if the ground water table is below the bottom of the tank. The bottoms of the KPS fuel oil storage tanks are above the

ground water level. Therefore, the 31 day water check requir ed by ISTS SR 3.8.3.5 has also been extended to 92 days.

5. ISTS 3.8.3 includes requirements for the starting air subsystem for each DG. In the ISTS, the starting air subsystem only includes the air receiver pressure. The required pressure in ISTS SR 3.8.3.4 is the design pressure (nominally the 5 start pressure), not the pressure needed for one start. The ISTS 3.8.3 ACTION E includes an allowance for a 48 hour5.555556e-4 days 0.0133 hours 7.936508e-5 weeks 1.8264e-5 months restoration time when the design pressure limit is not met, provided the one start pressure is met. This is explained in the ISTS Bases.

The KPS CTS does not include any requirements for the Starting Air Systems. Thus, as long as enough air is in each required air start receiver bank to start the DG one time, the pressure is acceptable. KPS has maintained this requirement in the ITS. The SR 3.8.3.4 pressure ensures that the DG can be started at least one time. If this limit is not met, then the DG will be immediately declared inoperable as required by ITS 3.8.3 ACTION E (See the third Condition of ITS 3.8.3 ACTION F). Therefore, ISTS 3.8.3 ACTION E is not necessary for the KPS ITS and has not been included. In addition, for KPS, the DGs are also dependent upon air for operation of the ventil ation system. The air compressors are required to ensure air is available in the air receiver banks to operate certain ventilation dampers in the DG rooms. Thus, the LCO statement has been

modified to reflect that the Starting Air Sy stem for each DG (which includes the air receiver bank pressure and the air compressor) must be OPERABLE. Furthermore, ITS 3.8.3 ACTION E has been added to provide actions for when one DG's air compressor is inoperable. The discussion and justification for this

new ACTION is provided in Discussion of Change L03. Lastly, a new

Surveillance has been added (ITS SR 3.8.3.5) to periodically verify the air compressors automatically operate to recharge the associated required air receiver bank. This is discussed and justified in Discussion of Change M03.

B 3.8.3 Diesel Fuel Oil, Lube Oil, and Starting Air

BASES BACKGROUND Each diesel generator (DG) is provided with a storage tank having a fuel oil capacity sufficient to operate that diesel for a period of 7 days while the DG is supplying maximum post loss of coolant accident load demand discussed in the FSAR, Section [9.5.4.2] (Ref. 1). The maximum load demand is calculated using the assu mption that a minimum of any two DGs is available. This onsite fuel oil capacity is sufficient to operate the DGs for longer than the time to repleni sh the onsite supply from outside sources. Fuel oil is transferred from storage tank to day tank by either of two

transfer pumps associated with each storage tank. Redundancy of pumps and piping precludes the failure of one pump, or the rupture of any pipe, valve or tank to result in the loss of more than one DG. All outside

tanks, pumps, and piping are located underground.

For proper operation of the standby DGs, it is necessary to ensure the proper quality of the fuel oil. Regulatory Guide 1.137 (Ref. 2) addresses the recommended fuel oil practices as supplemented by ANSI N195 (Ref. 3). The fuel oil properties governed by these SRs are the water and sediment content, the kinematic viscosity, specific gravity (or API gravity), and impurity level.

The DG lubrication system is design ed to provide sufficient lubrication to permit proper operation of its associated DG under all loading conditions. The system is required to circulate the lube oil to the diesel engine working surfaces and to remove excess heat generated by friction during operation. Each engine oil sump contains an inventory capable of supporting a minimum of [7] days of operation. [The onsite storage in addition to the engine oil sump is suff icient to ensure 7 days of continuous operation.] This supply is sufficient to allow the operator to replenish lube oil from outside sources.

Each DG has an air start system with adequate capacity for five successive start attempts on the DG without recharging the air start

receiver(s).

rated load as U 8.2.3.2 1 2 s a 1 1 2 Each DG has a Starting Air System that includes primary and reserve air receiver banks and an air compressor. Each primary and reserve air receiver bank has the capacity to start the DG and provide air to operate the DG room ventilation dampers. Normally, the primary air receiver bank is in service and the reserve air receiver bank is isolated. The air compressor operates to automatically maintain air receiver bank pressure above the limit. The air compressors ensure that sufficient pressure is maintained in the air receiver banks to operate the DGs.

APPLICABLE The initial conditions of Design Basis Accident (DBA) and transient SAFETY analyses in the FSAR, Chapter [6] (Ref. 4), and in the FSAR, ANALYSES Chapter [15] (Ref. 5), assume Engineered Safety Feature (ESF) systems are OPERABLE. The DGs are designed to provide sufficient capacity, capability, redundancy, and reliability to ensure the availability of

necessary power to ESF systems so that fuel, Reactor Coolant System and containment design limits are not exceeded. These limits are

discussed in more detail in the Bases for Section 3.2, Power Distribution Limits; Section 3.4, Reactor Coolant System (RCS); and Section 3.6, Containment Systems.

Since diesel fuel oil, lube oil, and the air start subsystem support the operation of the standby AC power sources, they satisfy Criterion 3 of 10 CFR 50.36(c)(2)(ii).

LCO Stored diesel fuel oil is required to have sufficient supply for 7 days of full load operation. It is also required to meet specific standards for quality.

Additionally, sufficient lubricating oil supply must be available to ensure the capability to operate at full load for 7 days. This requirement, in conjunction with an ability to obtain replacement supplies within 7 days, supports the availability of DGs required to shut down the reactor and to maintain it in a safe condition for an anticipated operational occurrence (AOO) or a postulated DBA with loss of offsite power. DG day tank fuel requirements, as well as transfer capability from the storage tank to the day tank, are addressed in LCO 3.8.1, "AC Sources - Operating," and LCO 3.8.2, "AC Sources - Shutdown." The starting air system is required to have a minimum capacity for five successive DG start attempts without recharging the air start receivers.

APPLICABILITY The AC sources (LCO 3.8.1 and LCO 3.8.2) are required to ensure the availability of the required power to shut down the reactor and maintain it in a safe shutdown condition after an AOO or a postulated DBA. Since stored diesel fuel oil, lube oil, and the starting air subsystem support LCO 3.8.1 and LCO 3.8.2, stored diesel fuel oil, lube oil, and starting air are required to be within limits when the associated DG is required to be OPERABLE.

ACTIONS The ACTIONS Table is modifi ed by a Note indicating that separate Condition entry is allowed for each DG. This is acceptable, since the Required Actions for each Condition provide appropriate compensatory actions for each inoperable DG subsystem. Complying with the Required 1 U 14 4 2 ing Air 3 rated for each DG each DG at rated s s 1 1 1 1 4 The Starting Air System for each DG is required to have a capacity to start and operate the DG. Thus, the air compressor is required to be OPERABLE, as well as one of the two air receiver banks is required to be OPERABLE and within the pressure limit.

ACTIONS (continued)

contaminated sampling equipment, and errors in laboratory analysis can produce failures that do not follow a trend. Since the presence of particulates does not mean failure of the fuel oil to burn properly in the

diesel engine, and particulate concentration is unlikely to change significantly between Surveillance Frequency intervals, and proper engine performance has been recently demonstrated (within 31 days), it is prudent to allow a brief period prior to declaring the associated DG inoperable. The 7 day Completion Time allows for further evaluation, resampling and re-analysis of the DG fuel oil.

D.1 With the new fuel oil properties defined in the Bases for SR 3.8.3.4 not

within the required limits, a period of 30 days is allowed for restoring the stored fuel oil properties. This period provides sufficient time to test the stored fuel oil to determine that the new fuel oil, when mixed with previously stored fuel oil, remains acceptable, or to restore the stored fuel oil properties. This restoration may involve feed and bleed procedures, filtering, or combinations of these procedures. Even if a DG start and load was required during this time interval and the fuel oil properties were outside limits, there is a high likelihood that the DG would still be capable of performing its intended function.

E.1 With starting air receiver pressure < [225] psig, sufficient capacity for five successive DG start attempts does not exist. However, as long as the receiver pressure is > [125] psig, there is adequate capacity for at least one start attempt, and the DG can be considered OPERABLE while the air receiver pressure is restored to the required limit. A period of 48 hours5.555556e-4 days 0.0133 hours 7.936508e-5 weeks 1.8264e-5 months is considered sufficient to complete restoration to the required pressure prior to declaring the DG inoperable. This period is acceptable based on the remaining air start capacity, the fact that most DG starts are accomplished on the first attempt, and the low probability of an event

during this brief period.

However, as long as both air receiver banks (primary and reserve) for the associated DG are in service and the air pressure in the two air receiver banks is > 200 psig, there is adequate capacity for at least one start and the DG can be operated for at least 48 hours5.555556e-4 days 0.0133 hours 7.936508e-5 weeks 1.8264e-5 months after the start. Therefore, the DG can be considered OPERABLE. These compensatory actions (Required Actions E.1 and E.2) must be met within 1 hour1.157407e-5 days 2.777778e-4 hours 1.653439e-6 weeks 3.805e-7 months . Provided the compensatory measures are met, a period of 48 hours5.555556e-4 days 0.0133 hours 7.936508e-5 weeks 1.8264e-5 months is allowed to restore the air compressor to OPERABLE status. If at any time during the 48 hours5.555556e-4 days 0.0133 hours 7.936508e-5 weeks 1.8264e-5 months Required Action E.1 or E.2 is not met, ACTION F must be entered. The 48 hours5.555556e-4 days 0.0133 hours 7.936508e-5 weeks 1.8264e-5 months is acceptable based on an analysis that shows that with both air receiver banks in service and at a pressure of 200 psig, sufficient air remains to start the DG and operate it for at least 48 hours5.555556e-4 days 0.0133 hours 7.936508e-5 weeks 1.8264e-5 months . In addition, the capability exists to cros s-tie the other DG's Starting Air System and recharge the inoperabl e air compressor's associated air receiver banks. Furthermore, the probability of an event requiring operation of the DGs during this period is low.

Required Action E.2 is modified by a N ote that allows the cross-tie between the DG Starting Air Systems to be intermittently opened under administrative control to achieve and maintain the inoperable Starting Air System air receiver banks within the pressure limit of the Required Action. These administrative controls consist of stationing a dedicated operator at the DG Starting Air System cross-connect valve for the OPERABLE DG, who is in continuous communic ation with the control room. In this way, the OPERABLE Starting Air System can be isolated from the inoperable Starting Air System if a need for isolati on is indicated. Furthermor e, for the OPERABLE DG, only the cross-connect valve for the isolated air receiver bank should be opened. The time the cross-connect valves are opened should be minimized.

F.1 With a Required Action and associated Completion Time not met, or one or more DG's fuel oil, lube oil, or starting air subsystem not within limits for reasons other than addressed by Conditions A through D, the associated DG may be incapable of performing its intended function and must be immediately declared inoperable. one or more DGs with required air receiver bank pressure not within limits, or both DGs with Starting Air System inoperable due to an inoperable air compressor either or 4 SURVEILLANCE SR 3.8.3.1 REQUIREMENTS This SR provides verification that there is an adequate inventory of fuel oil in the storage tanks to support each DG's operation for 7 days at full load. The 7 day period is sufficient time to place the unit in a safe shutdown condition and to bring in replenishment fuel from an offsite location.

4 1 associated and corresponding day tanks (combined) The 31 day Frequency is adequate to ensure that a sufficient supply of fuel oil is available, since low level alarms are provided and unit operators would be aware of any large uses of fuel oil during this period.

SR 3.8.3.2 This Surveillance ensures that sufficient lube oil inventory is available to support at least 7 days of full load operation for each DG. The [500] gal requirement is based on the DG manufacturer consumption values for the run time of the DG. Implicit in this SR is the requirement to verify the capability to transfer the lube oil from its storage location to the DG, when the DG lube oil sump does not hold adequate inventory for 7 days of full load operation without the level reaching the manufacturer recommended minimum level.

504 2 A 31 day Frequency is adequate to ensure that a sufficient lube oil supply

is onsite, since DG starts and run time are closely monitored by the unit staff.

SR 3.8.3.3

The tests listed below are a means of determining whether new fuel oil is of the appropriate grade and has not been contaminated with substances that would have an immediate, detrimental impact on diesel engine combustion. If results from these tests are within acceptable limits, the fuel oil may be added to the storage tanks without concern for A ttachment 1, Volume 13, Rev. 0, Page 125 of 289 A ttachment 1, Volume 13, Rev. 0, Page 125 of 289 Enclosure (1 of 4), Q&A to Attachment 1, Volume 13 (Section 3.8) Page 37 of 41 Enclosure (1 of 4), Q&A to Attachment 1, Volume 13 (Section 3.8) Page 37 of 41 E 4 Diesel Fuel Oil, Lube Oil, and Starting Air B 3.8.3 WOG STS B 3.8.3-7 Rev. 3.0, 03/31/04 BASES

SURVEILLANCE REQUIREMENTS (continued)

Particulate concentrations should be determined in accordance with ASTM D5452-[ ] (Ref. 6). This method involves a gravimetric determination of total particulate concentration in the fuel oil and has a

limit of 10 mg/l. It is acceptable to obtain a field sample for subsequent laboratory testing in lieu of field testing. [For those designs in which the total stored fuel oil volume is contained in two or more interconnected tanks, each tank must be considered and tested separately.]

The Frequency of this test takes into consideration fuel oil degradation trends that indicate that particulate concentration is unlikely to change

significantly between Frequency intervals.

SR 3.8.3.4

This Surveillance ensures that, without the aid of the refill compressor, sufficient air start capacity for each DG is available. The system design requirements provide for a minimu m of [five] engine start cycles without recharging. [A start cycle is defined by the DG vendor, but usually is measured in terms of time (seconds of cranking) or engine cranking

speed.] The pressure specified in this SR is intended to reflect the lowest value at which the [five] starts can be accomplished.

The 31 day Frequency takes into account the capacity, capability, redundancy, and diversity of the AC sources and other indications available in the control room, incl uding alarms, to alert the operator to below normal air start pressure.

SR 3.8.3.5

Microbiological fouling is a major cause of fuel oil degradation. There are numerous bacteria that can grow in fuel oil and cause fouling, but all must have a water environment in order to survive. Removal of water from the fuel storage tanks once every [31] days eliminates the necessary

environment for bacterial survival. This is the most effective means of controlling microbiological fouling. In addition, it eliminates the potential for water entrainment in the fuel oil during DG operation. Water may 1 2 6217-98 fuel oil storage 20 seconds of starting air from each of the two air receiver banks (primary and reserve) air one 4 1 4 5 92 bound , only the pressure to start the DG one time is required to meet the OPERABILITY requirements (since the accident analysis assumes the DG starts on the first attempt) While the 6 SR 3.8.3.5 This Surveillance ensures that the air compressor operates automatically to recharge the required air receiver bank. This is required to support continuous operation of the associated DG. This Surveillance provides assurance that the air compressor is OPERABLE, the piping to the air receiver banks is intact, the air delivery piping is not obstructed, and the controls and control systems for automatic air compressor operation are OPERABLE.

The Frequency of this SR is 31 days, since the air compressor will normally operate during or following DG testing to recharge the air receiver banks.
