(

BASES APPLICABLE The RCS pressure SL has been selected such that it is at a SAFETY ANALYSES pressure below which it can be shown that the integrity of (continued) the system is not endangered. The reactor pressure vessel is designed to ASME, Boiler and Pressure Vessel Code,Section III, 1971 Edition, including Addenda through the winter of 1972 (Ref. 5), which permits a maximum pressure transient of 1107,, 1375 psig, of design pressure 1250 psig.

The SL of 1325 psig, as measured in the reactor steam dome, is equivalent to 1375 psig at the lowest elevation of the RCS. The RCS is designed to ASME Code,Section III, 1974 Edition (Ref. 6), for the reactor recirculation piping, which permits a maximum pressure transient of 1107,of design pressures of 1250 psig for suction piping,1650 psig for discharge piping between the pump and the discharge valve, and 1550 psig beyond the discharge valve. The RCS pressure SL is selected to be the lowest transient overpressure allowed by the applicable codes.

SAFETY LIMITS The maximum transient pressure allowable in the RCS pressure vessel under the ASME Code,Section III, is 1107,of design pressure. The maximum transient pressure allowable in the

(

RCS piping, valves, and fittings is 1107, of design pressures of 1250 psig for suction piping,1650 psig for discharge piping between the pump and the discharge valve, and 1550 psig beyond the discharge valve. The most limiting of these allowances is the 1107, of the suction piping design pressure; therefore, the SL on maximum allowable RCS pressure is established at 1325 psig as measured at the reactor steam dome.

Exceptions to LCO 3.0.4 are stated in the individual i

F Knecifications.4 Exceptions may apply to all the ACTIONS or L g 9 (,.A \\

to a specific Required Action of a Specification.

LC0 3.0.4 is only applicable when entering MODE 3 from MODE 4, MODE 2 from MODE 3 or 4, or MODE 1 from MODE 2.

Furthermore, LCO 3.0.4 is applicable when entering any other specified condition in the Applicability only while operating in MODE 1, 2, or 3.

The requirements of LCO 3.0.4 do not apply in MODES 4 and 5, or other specified conditions of the Applicability (unless in MODE 1, 2, or 3) because the ACTIONS of individual Specifications sufficiently define'the remedial measure to be taken.

The ACTIONS for an inoperable required battery charger in LCO 3.8.4, "DC Sources - Operating," and LCO 3.8.5, "0C Sources - Shutdown," include a Note explicitly precluding I.

entry into specific MODES or other specified conditions of the Applicability while relying on the ACTIONS. With an inoperable required battery charger this Note in LCO 3.8.4 prohibits entry in MODE 1, 2, or 3, except during power decrease and in LCO 3.8.5 prohibits starting movement of irradiated fuel, entering MODE 4 from MODE 5, or loading fuel into the vessel if the vessel is defueled.

Surveillances do not have to be performed on the associated inoperable equipment (or on variables outside the specified limits), as permitted by SR 3.0.1.

Therefore, changing MODES or other specified conditions whila in an ACTIONS Condition, either in compliance with LCO 3.0.4, or where an exception to LCO 3.0.4 is stated, is not a violation of SR 3.0.1 or SR 3.0.4 for those Surveillances that do not have to be performed due to the associated inoperable equipment. However, SRs must be met to ensure OPERABILITY prior to declaring the associated equipment OPERABLE (or variable within limits) and restoring compliance with the affected LCO.

-(

BASES LCO satisfy the intended reactivity control requirements, strict (continued) control over the number and distribution of inoperable control rods is required to satisfy the assumptions of the DBA and transient analyses.

APPLICABILITY In MODES I and 2, the control rods are assumed to function during a DBA or transient and are therefore required to be i

OPERABLE in these MODES.

In MODES 3 and 4, control rods are not able to be withdrawn since the reactor mode switch is in Shutdown and a control rod block is applied. This provides adequate requirements for control rod OPERABILITY during these conditions. Control rod requirements in MODE 5 are i

located in LCO 3.9.5, " Control Rod OPERABILITY-Refueling."

ACTIONS The ACTIONS table is modified by a Note indicating that a separate Condition entry is allowed for each control rod.

'~

This is acceptable, since the Required Actions for-each Condition provide appropriate compensatory actions for each inoperable control rod. Complying with the Required Actions may allow for continued operation, and subsequent inoperable control rods are governed by subsequent Condition entry and i

application of associated Required Actions.

h.l.A.2 A.

A control rod is considered stuck if it will not insert by either CRD drive water or scram pressure. With a fully inserted control rod stuck, no actions are required as long as the control rod remains fully inserted. The Required Actions are modified by a Note that allows a stuck control rod to be bypassed in the Rod Action Control System (RACS) to allow continued operation. SR 3.3.2.1.9 provides additional requirements when control rods are bypassed in i

be* l RACS to ensure compliance with the CRDA analysis. With one i'

withdrawn control rod stuck the control rod must be 4

• w. withdrawn dua centr:1 red.

Table 3.1.4-1 is modified by two No'tes, which state control rods with scram times not within the limits of the Table are considered " slow" and that control rods with scram times

> 7 seconds are considered inoperable as required by SR 3.1.3.4.

This LCO applies only to OPERABLE control rods since inoperable control rods will be inserted and disarmed (LC03.1.3). Slow scramming control rods may be conservatively declared inoperable and not accounted for as

" slow" control rods.

APPLICABILITY In MODES I and 2, a scram is assumed to function' d'uring transients and accidents analyzed for these plant conditions. These events are assumed to occur during startup and power operation; therefore, the scram function

(

of the control rods is required during these MODES.

In MODES 3 and 4, the control rods are not able to be withdrawn since the reactor mode switch is in shutdown and a control I

rod block is applied. This provides adequate requirements for control rod scram capability during these conditions.

Scram requirements in MODE S are contained in LC0 3.9.5,

" Control Rod OPERABILITY-Refueling."

ACTIONS A.1 When the requirements of this LCO are not met, the rate of negative reactivity insertion during a scram may not be within the assumptions of the safety analyses.

Therefore, the plant must be brought to a MODE in which the LCO does not apply. To achieve this status, the plant must be brought to MODE 3 within 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br />.

To minimize the wear on moving parts that do not get lubricated when the engine is not running, this SR is modified by a Note to indicate that all DG starts for this Surveillance may be preceded by an engine prelube period and followed by a warmup period prior to loading.

For the purposes of this testing, the DGs are started from standby conditions. Standby conditions for a DG mean that the diesel engine coolant and oil are being continuously circulated and temperature is being maintained consistent with manufacturer recommendations for DG 11 and DG 12.

For DG 13, standby conditions mean that the lube oil is heated by the jacket water and continuously circulated.throu.gh a portion of the system as recommended by the vendor.

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 storage tanks once every 92 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 come from any of several sources, including condensation, ground water, rain water, contaminated fuel oil, and from breakdown of the fuel oil by bacteria.

Frequent checking for and removal of accumulated water minimizes fouling and provides data regarding the watertight integrity of the fuel oil system. The Surveillance Frequencies are established by Regulatory Guide 1.137 (Ref. 2).

BASES APPLICABLE Although the RHR System does not meet a specific criterion SAFETY ANALYSES of the NRC Policy Statement, it was identified in the NRC (continued)

Policy Statement as an important contributor to risk reduction.

Therefore, the RHR System is retained as a Specification. The ADHRS is included in the Specification to provide requirements for decay heat removal capability during an outage while the RHR System is out of service.

LCO Only one RHR shutdowr, cooling subsystem is required to be OPERABLE in MODE 5 with irradiated fuel in the RPV and the water level 2. 22 ft 8 inches above the RPV flange. Only one subsystem l's required because the volume of water above the RPV flange provides backup decay heat removal capability.

An OPERABLE RHR shutdown cooling subsystem consists of an RHR pump, two heat exchangers, valves, piping, instruments, and controls to ensure an OPERABLE flow path. The required RHR shutdown cooling subsystem must have a OPERABLE diesel generatoi capable of supplying electrical power.

Additionally, each RHR shutdown cooling subsystem is considered OPERABLE if it can be manually aligned (remote or local) in the shutdown cooling mode' for removal of decay heat. Operation (either continuous or intermittent) of one decay heat removal subsystem (either'RHR or ADHRS) can maintain and reduce the reactor coolant temperature as required.

i APPLICABLE Specification.

The ADHRS is included in the Specification SAFETY ANALYSES to provide requirements for decay heat removal capability (continued) during an outage while the RHR System is out of service.

LCO In MODE 5 with irradiated fuel in the reactor pressure vessel (RPV) and the water level < 22 ft 8 inches above the RPV flange both RHR shutdown cooling subsystems must be OPERABLE, or the ADHRS may be substituted for one of the RHR subsystems.

An OPERABLE RHR shutdown cooling subsystem consists of an RHR pump, two heat exchangers, valves, piping, instruments, and controls to ensure an OPERABLE flow path. An OPERABLE ADHRS consists of two pumps, two heat exchangers, valves, piping, instruments and controls to ensure an OPERABLE flow path.

At least one of the reqaired RHR shutdown cooling subsystems must have a OPERABLE diesel generator capable of i

supplying electrical power.

Additionally, each RHR shutdown cooling subsystem is considered OPERABLE if it can be manually aligned (remote or local) in the shutdown cooling mode for removal of decay heat.

Operation (either continuous ~or intermittent) of one decay heat removal subsystem (either RHR or ADHRS) can i

maintain and reduce the reactor coolant temperature as required. However, to ensure adequate core flow to allow 4*

k for accurate average reactor coolant temperature monitoring, nearly continuous operation is re uired. A Note is provided BPM "O to allow a 2 hour2.314815e-5 days <br />5.555556e-4 hours <br />3.306878e-6 weeks <br />7.61e-7 months <br /> exceptio

APPLICABILITf Two decay heat removal subsystems are required to be OPERABLE in MODE 5, with irradiated' fuel in the RPV and the water level < 22 ft 8 inches above the top of the RPV flange, to provide decay heat removal.

RHR System requirements in other MODES are covered by LCOs in i

Section 3.4, Reactor Coolant System (RCS); Section 3.5, Emergency Core Cooling Systems (ECCS) and Reactor Core Isolation Cooling (RCIC) System; and Section 3.6, Containment Systems.

B 2.1.2 l

BASES APPLICABLE The RCS pressure SL has been selected such that it is at a SAFETY ANALYSES pressure below which it can be shown that the integrity of (continued) the system is not endangered. The reactor pressure vessel is designed to ASME, Boiler and Pressure Vessel Code,Section III, 1971 Edition, including Addenda through the winter of 1972 (Ref. 5), which permits a maximum pressure transient of 110%, 1375 psig, of design pressure 1250 psig.

The.SL of 1325 psig, as measured in the reactor steam dome, is equivalent to 1375 psig at the lowest elevation of the RCS. The RCS is designed to ASME Code,Section III, 1974 Edition (Ref. 6), for the reactor recirculation piping, which permits a maximum pressure transient of 110% of design pressures of 1250 psig for suction piping,1650 psig for discharge piping between t'ie pump and the discharge valve, and 1550 psig beyond the discharge valve. The RCS pressure SL is selected to be the lowest transient overpressure allowed by the applicable codes.

SAFETY LIMITS The maximum transient pressure allowable in the RCS pressure vessel under the ASME Code,Section III, is 110% of design pressure. The maximum transient pressure allowable in the RCS piping, valves, and fittings is 110% of design pressures of 1250 psig for suction piping,1650 psig for discharge piping between the pump and the discharge valve, and 1550 psig beyond the discharge valve. The most limiting of these allowances is the 110% of the suction piping design pressure; therefore, the SL on maximum allowable RCS pressure is established at 1325 psig as measured at the reactor steam dome.

APPLICABILITY SL 2.1.2 applies in all MODES.

Furthermore, LCO 3.0.4 is applicable when entering any other specified condition in the Applicability only while operating in MODE 1, 2, or 3.

The requirements of LCO 3.0.4 do not apply in MODES 4 and 5, or other specified conditions of the Applicability (unless in MODE 1, 2, or 3) because the ACTIONS of individual Specifications sufficiently define'the remedial measure to be taken.

The ACTIONS for an inoperable required battery charger in LCO 3.8.4, "DC Sources - Operating," and LCO 3.8.5, "DC Sources - Shutdown," include a Note explicitly precluding entry into specific M00Es or other specified conditions of the Applicability while relying on the ACTIONS. With an inoperable required battery charger this Note in LCO 3.8.4 prohibits entry in MODE 1, 2, or 3, except during power decrease and in LC0 3.8.5 prohibits starting movement of irradiated fuel, entering MODE 4 from MODE 5, or loading fuel into the vessel if the vessel is defueled.

Surveillances do not have to be performed on the associated inoperable equipment (or or variables outside the specified limits), as permitted by SR 3.0.1.

Therefore, changing MODES or other ;pecified conditions while in an ACTIONS Condition, either in compliance with LCO 3.0.4, or where an exception to LCO 3.0.4 is stated, is not a violation of SR 3.0.1 or SR 3.0.4 for those Surveillances that do not have to be performed due to the associated inoperable equipment. However, SRs must be met to ensure OPERABILITY prior to declaring the associated equipment OPEPABLE (or variable within limits) and restoring compliance with the i

In MODES 3 and 4, control rods are not able to be withdrawn since the reactor mode switch is in Shutdown and a control rod block is applied. This provides adequate requirements for control rod OPERABILITY during i

these conditions. Control rod requirements in MODE 5 are located in LCO 3.9.5, " Control Rod OPERABILITY-Refueling."

ACTIONS The ACTIONS table is modified by a Note indicating that-a separate Condition entry is allowed for each control rod.

This is acceptable, since the Required Actions for each Condition provide appropriate compensatory actions for each inoperable control rod. Complying with the Required Actions may allow for continued operation, and subsequent inoperable control rods are governed by subsequent Condition entry and application of associated Required Actions.

This LCO applies only to OPERABLE control rods since inoperable control rods will be inserted and disarmed (LC03.1.3). Slow scramming control rods may be conservatively declared inoperable and not accounted for as

" slow" control rods.

APPLICABILITY In MODES I and 2, a scram is assumed to function du' ring

' of the control rods is required during these MODES.

In MODES 3 and 4, the control rods are not able to be withdrawn since the reactor mode switch is in shutdown and a control I

rod block is applied. This provides adequate requirements for control rod scram capability during these conditions.

LC0 The drywell floor drain sump monitoring system is required to quantify the unidentified LEAKAGE from the RCS. Thus, for the system to be considered OPERABLE, the sump level monitoring portion of the system must be OPERABLE. The other monitoring systems provide qualitative indication to the operators so closer examination of other detection systems will be made to determine the extent of any corrective action that may be required. With the leakage detection systems inoperable, monitoring for LEAKAGE in the RCPB is degraded.

Movement of irradiated fuel assemblies in the primary or secondary containment, CORE ALTERATIONS, and OPDRVs can be postulated to cause fission product release to the secondary containment.

In such cases, the secondary containment is the only barrier to release of fission products to the environment. CORE ALTERATIONS and movement of irradiated fuel assemblies must be immediately suspended if the i

secondary containment is inoperable.

Suspension of these activities shall not preclude completing an action that involves moving a component to a safe position. Also, action must be immediately initiated to suspend OPDRVs to minimize the probability of a vessel draindown and subsequent potential for fission product release.. Actions must continue until OPDRVs are suspended.

Req'uired Action C.1 has been modified by a Note stat.ing that LCO 3.0.3 is not. applicable.

If moving irradiated fuel assemblies while in MODE 4 or 5, LCO 3.0.3 would not specify any action.

If moving irradiated fuel assemblies while in MODE 1, 2, or 3, the fuel movement is independent of reactor operations. Therefore, in either case, inability to suspend movement of irradiated fuel assemblies would not be a sufficient reason to require a reactor shutdown.

This SR helps to ensure the availability of the standby electrical power supply to mitigate DBAs and transients and maintain the unit in a safe shutdown condition.

To minimize the wear on moving parts that do not get lubricated when the engine is not running, this SR is modified by a Note to indicate that all DG starts for this Surveillance may be preceded by an engine prelube period and followed~by a warmup period prior to loading.

For the purposes of this testing, the DGs are started from standby conditions.

Standby conditions for a DG mean that the diesel engine coolant and oil are being continuously circulated and temperature is being maintained consistent with manufacturer recommendations for DG 11 and DG 12.

For DG 13, standby conditions mean that the lube oil is heated by the jacket water and continuously circulated through a portion of the system as recommended by the vendor.

Engine jacket water is heated by an immersion heater and circulates

'through the system by natural circulation.

^

SR 3.8.1.2 requires that the DG starts from standby conditions and achieves required voltage and frequency within 10 seconds. The DG's ability to maintain the required voltage and frequency is tested by those SRs which require DG loading. The 10 second start requirement 2* \\

supports the assumptions in the design basis LOCA analysis r

u83,1-MA (Ref. 5)S The DGs are started for this test by using one of the following signals: manual, simulated loss of offsite power by itself, simulated loss of offsite power in conjunction TI

signal by itself.

The 31 day Frequency for SR 3.8.1.2 is consistent with the industry guidelines for assessment of diesel generator performance (Ref. 14). This Frequency provides adequate assurance of DG OPERABILITY, while minimizing degradation resulting from testing.

SURVEILLANCE SR 3.8.3.5 REQUIREMENTS 1

(continued)

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 storage tanks once every 92 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 come from any of several sources, including condensation, ground water, rain water, contaminated fuel oil, and from breakdown of the fuel oil by bacteria.

Frequent checking for and removal of accumulated water minimizes fouling and provides data regarding the watertight integrity of the fuel oil system, The Surveillance Frequencies are established by RegulatoryGuide1.137(Ref.2). This SR is for preventive maintenance.

REQUIREMENTS i

Verifying battery terminal voltage while on float charge I

helps to ensure the effectiveness of the charging system and the ability of the batteries to perform their intended I

function. Float charge is the condition in which the L

charger is supplying the continuous charge required to overcome the internal losses of a battery (or battery cell) and maintain the battery (or battery cell) in a fully charged state. The voltage requirements are based on the nominal design voltage of the battery and are censistent with the initial voltages assumed in the battery sizing calculations. The 7 day Frequency is consistent with manufacturer's recommendations and IEEE-450 (Ref. 8).

SR 3.8.4.2 Visual inspection to detect corrosion of the battery cells and connections, or measurement of the resistance of each inter-cell, inter-rack, inter-tier, and terminal connection, provides an indication of physical damage or abnormal deterioration that could potentially degrade battery I-performance.

The Surveillance Frequency for these inspections, which can detect conditions that can cause' power losses due to resistance heating, is 92 days. This Frequency is considered acceptable based on operating experience related to detecting corrosion trends.

SR 3.8.4.3 Visual inspection of the battery cells, cell plates, and

{6 35-5G A g,-&

battery racks provides an indication of physical damage or abnormal deterioration that could potentially degrade q battery performance. 3 The 18 month Frequency of the Surveillance is based on engineering judgement, taking into consideration the desired unit conditions to perform the Surveillance. Operating experience has shown that these components usually pass the SR when performed at the 18 month Frequency. Therefore, the Frequency was concluded to be acceptable from a reliability standpoint.
