3.1 PRIMARY COOLANT SYSTEM Applicability Applies to the operable status of the primary coolant system.

Objective To specify certain conditions of the primary coolant system which must be met to assure safe reactor operation.

Specifications 3.1.1 Operable Components TSPR8902

a.

At least one primary coolant pump or one shutdown cooling pump with a flow rate greater than or equal to 2810 gpm shall be in operation whenever a change is being made in the boron concentration of the primary coolant and the plant is operating in cold shutdown or above, except during an emergency loss of coolant flow situation. Under these circumstances, the boron concentration may be increased with no primary coolant pumps or shutdown cooling pumps running.

b.

Four primary coolant pumps shall be in operation whenever the reactor is operated above hot shutdown, with the following exception:

Before removing a pump from service, thermal power shall be reduced as specified in Table 2.l.1 and appropriate corrective action implemented.

With one pump ant of service, return the pump to service within 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br /> (return to four-pump operation) or-be in hot shutdown (or below.). with. the reactor td pped (from the C-06 panel, opening the 42-01 and 42-02 circuit breakers) within the next 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br />.

Start-up (above hot shutdown) with less than four pumps is no.t permitted and power operation with less than three pumps is not_permitted.

c.

• The measured four primarl coolant pumps operating reactor vessel flow shall be 140.7 x 10 lb/hr or greater, when corrected to 532° F.

d.

Both steam generators shall be capable of performing their heat transfer function whenever the average temperature of the primary coolant is above 300°F.

(4)

(5)

Primary coolant cold leg temperature is > 430°F.

PCS cold leg temperature is ~ 430°F and S/G secondary temperature is less than PCS cold leg temperature.

Shutdown cooling is isolated from the PCS AND PCS cold leg temperature is > 2I0°F and S/G secondary temperature is less than I00°F hi~her than PCS temperature.

Shutdown cooling is isolated from the PCS AND PCS cold leg temperature is ~ I70°F and

~ 2I0°F AND S/G secondary temperature is less than 20°F higher than PCS cold leg temperature.

Shutdown cooling is isolated from the PCS AND PCS cold leg temperature is ~ I20°F and < I70°F AND S/G secondary temperature is less than I00°F higher than PCS cold leg temperature.

i. The PCS shall not be heated or maintained above 300°F unless a minimum of 375 kW of pressurizer heater capacity is available from both buses ID and IE.

Should heater capacity from either bus ID and IE fall below 375 Kw, either restore the inoperable heaters to provide at least 375 Kw of heater capacity from both buses ID and IE within 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br /> or be in hot shutdown within the next I2 hours.

Basis When primary co;olant boron concentration is being changed, the process must be uniform throughout the primary coolant system volume to prevent stratification of primary coolant at lower boron concentration which could resul~ in a reactivity insertinn.

Sufficient mixing of the primary coolant is assured if one shutdown cooling or one primary coolant pump is in operation.<

1> The shutdown cooling pump will circulate the primary syste.m volume in less than 60 minutes when operated at rated capacity.

By imposing a minimum shutdown cooling pump flow rate of 28IO gpm, sufficient time is provided for the operator to terminate the boron dilution under asymmetric flow conditions.<

5> The pressurizer volume is relatively inactive, therefore will tend to have a boron concentration higher than rest of the primary cool ant system during a dilution operation.

Administrative procedures will provide for use of pressurizer sprays to maintain a nominal spread between the boron concentration in the pressurizer and the primary system during the addition of boron. <

.3. l.'9 TSPR8902 PRIMARY CO~ SYSTEM CPCS) (Continued)

SHUTDOWN COOLING (Continued)

BASIS A shutdown cooling train may vary in actual component configuration, method of operation and control, but it shall always accomplish the objective of transferring decay heat from the reactor to Lake Michigan as the ultimate heat sink.

As a minimum, a shutdown cooling train requires: a shutdown cooling pump, one component cooling water pump, one service water pump, and appropri~te piping, valves and controls for the equipment to perform its function.

All of this equipment must also have adequate electrical power to be operable.

"Loops filled" means the Primary Coolant System (PCS) loops are intact, not blocked by dams and totally filled with coolant. This permits partial draining of the PCS provided air has not entered the PCS loops.

The loops are considered "not filled" after the PCS has been drained so air has entered the loo~s and air sweeps have not been completed

• to remove the air. Once the PCS loops have been drained to any extent (install, steam generator nozzle dams for example) there could be sufficient air trapped in the upper portion of the steam generator u-tubes, even after the PCS water level is raised, to prevent natural circulation in the PCS.

For this reason, the steam generators cannot be considered operable when the PCS loops.are not completely filled

.with coolant and the air sweeps completed.

With the PCS temperature >200°F and ~300°F a single primary coolant loop or shutdown cooling train provides sufficient heat removal capability for removing decay heat. Natural circulation is adequate for core heat removal, however it may not provide adequate mixing of the PCS coolant during PCS boron concentration changes. Therefore, forced circulation is required during these operating conditions,

~xcept durtng intefvals when the required loops or trains can be intentionally re~dered inop~rable provided additiohal constraints are followed.

Single fatlur~ considerations require a second loop or train (either PCS or shutdown cooling) be operable.* Operation of the shutdown cooling trains is limited to when the PCS temperature is

~300°F because 300°F is the maximum temperature used in the stress analysis of the shutdown cooling system piping.

When the PCS temperature <200°F and the loops filled, a single primary coolant loop or shutdown cooling train provides sufficient heat removal capability for removing decay heat.

The steam generators remove heat by bulk heating of the secondary side water rather that treating steam.

Natural circulation is adequate as a ba~kup means for core heat removal, however it may not provide adequate mixing of *the* *pcs cool ant dliri ng* PCS boron concentration changes.

In addition, it is difficult to maintain PCS temperature

<200°F, if the only method of core heat removal is natural circulation. Therefore, forced circulation is required during these operating conditions, except during intervals when the required loops or trains can be intentionally secured provided additional constraints are followed.

Single failure considerations require a 3-25g Amendment No.

PRIMARY COO. SYSTEM (PCS) (Continued)

SHUTDOWN COOLING (Continued)

BASIS (Continued) second loop, train, or the secondary side water level of both steam generators be above the actual minus 84 percent level.

Minus 84 percent is located 197.9 inches below the centerline of the main feedwater ring. A steam generator secondary water level of at least minus 84 percent covers at least one-third of the effective steam generator heat transfer area and is sufficient to support natural circulation in the PCS 0

• 2>.

With the PCS temperature ~200°F and the loops not filled, a sin~le shutdown cooling train provides sufficient heat removal capability for removin~ decay heat.

To provide adequate mixing of the PCS coolant during PCS boron concentration changes, forced circulation is required duririg this operating condition except during intervals when the required trains can be intentionally rendered inoperable provided additional constraints are followed.

Single failure considerations, and the unavailability of the steam generators as a heat removing component, require that a second shutdown cooling train be operable.

All forced circulation may be isolated provided actions are taken to prevent dilution of the PCS and avoid situations that could produce steam in the reactor vessel.

When the PCS temperature is >200°F and

<300°F, maintaining ~10°F subcooling ensures the availability of single phase natural circulation.

When the PCS temperature is

~200°F, not exceeding 200°F ensures the availability of a single phase natural circulation.

-A redundant train of SOC may be intentionally rendered inoperable for testin~ or maintenance for any time interval provided the other SOC train is in operation.

The two shutdown cooling trains are not totally independent since they share common suction and discharge piping.

No time limit is specified because the time interval that is needed for each required evolution could vary.

This method of oper9ting equipment is consistent with the intent of Generic Letter 88-17, Loss of Decay Heat Removal.

It i~ recommended that equipment be maintained and tested as appropriate to create an acceptable level of confidence that the systems will be able to perform their decay heat removal function.

Therefore, appropriate testin~ or maintenance is considered prudent and justified, without any specific time limit related to equipment that may be inoperable to permit such evolutions.

In all cases, the intent is to take reasonable actions to minimize the use of exception No. 1 of specification 3.1.9.c. If it is required to use exception No. 1 of specification 3.1.9.c, SOC will not be rendered inoperable in situations where PCS temperature is close to 200°F or the PCS heatup rate would result in the PCS temperature exceeding 200°F in a relatively short period of time.

SHUTDOWN COOLING ELECTRICAL REQUIREMENTS (Continued)

The operability of the minimum specified power sources and associated distribution systems during shutdown and refueling ensures that:

1.

The plant can be maintained in the shutdown or refueling operation condition for extended time periods~ and

2.

Sufficient control capability is available for maintaining the plant status.

When a single train of shutdown cooling must be operable to meet the minimum equipment operability requirements to remove decay heat, the train must still function following the loss of one electric supply (offsite power or diesel generator).

When two trains of shutdown cooling must be operable to meet the minimum equipment operability requirements to remove decay heat, the loss of any single pump or the loss of one electrical supply (offsite power or diesel generator) must still leave a shutdown cooling train operable.

The action statements will minimize the occurrence of postulated events, however, they should not preclude the orderly completion of an activity, such as fuel movement or crane operation, in order to get into a safe_ and conservative position.

. 3. 1 PRIMARY COOLA~'STEM App 1 i cabil ity Applies to the operable status of the primary coolant system.

Obiective To specify certain conditions of the primary coolant system which must be met to assure safe reactor operation.

Specifications 3.1.1 Operable Components

a.

At least one primary coolant pump or one shutdown cooling pump with a flow rate greater than or equal to 2810 gpm shall be in operation whenever a change is being made in the boron concentration of the primary coolant and the plant is operating in cold shutdown or above, except during an emergency loss of coolant flow situation. Under these circumstances, the boron concentration may be increased with no primary coolant pumps or shutdown cooling pumps running.

b.

Four primary coolant pumps shall be in operation whenever the reactor is operated above hot shutdown, with the following exception:

Before removing a pump from service, thermal power shall be reduced as specified in Table 2.3.1 and appropriate corrective action implemented.

With one pump ont of service, return the pump to service within 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br /> (return to four-pump operation}

c.

The measured four primarl coolant pumps operating reactor vessel

.flow shall be 140.7 x 10 lb/hr or greater, when corrected to

~

h.

Forced circulation (starting the first primary coolant pump) shall not be initiated unless one of the following conditions is met:

(1)

Primary coolant cold leg temperature is > 430°F.

(2}

PCS cold leg temperature is :ii 430°F and S/G secondary temperature is less than PCS cold leg temperature.

(3)

Shutdown cooling is isolated from the PCS AND PCS cold leg temperature is > 210°F AND S/G secondary temperture is less than 100°F higher than PCS temperature.

(4)

Shutdown cooling is isolated from the PCS AND PCS cold leg temperature is ~ 170°F and ~ 210°f AND S/G secondary temperature is less than 20°F higher than PCS cold leg temperature.

(5)

Shutdown cooling is isolated from the PCS AND PCS cold leg temperature is ~ 120°F and < 170°F AND S/G secondary temperature is less than 100°F higher than PCS cold leg temperature.

JOO

i. The PCS shall not be heated or maintained above ~F unless a

/

minimum of 375 kW of pressurizer heater capacity is available from both buses lD and. lE.

Should heater capacity from either bus lD and lE fall below 375 kW, either restore the inoperable heaters to provide at least 375 kW of heater capacity from both buses lD and lE within 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br /> or be in hot shutdown within the next 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br />.

Basis When primary coolant boron concentration.is being changed, the process must be uniform throughout the primary coolant system volume to prevent stratification of.primary coolant at lower boron concentration which could result in a reactivity insertion.

Sufficient mixing of the primary coolant is assured if one shutdown cooling or one primary coolant pump is in operation. (l)

Th~

shutdown cooling pump will circulate the primary system volume in less than 60 minutes when operated at rated capacity.

By imposing a minimum shutdown coolinR pump flow rate of 2810 gpm, sufficient t.ime is provided for the operatofsfo terminate the boron dilution.under asymmetric flow conditions.

. The pressurizer volume is relatively inactive-, therefore vill tend. to have a boron concentration higher than r**t of the primary coolant system during a dilution operation.

A4wfnf8trative procedures will provide for use of pressurizer sprays to maintain a nominal spread between the boron concentration in (2) tb* pr**aurizer and the primary system during the addition of boron.

Natural circulation is adequate as a backup means for core heat removal, however it may not provide adequate mixing of the PCS coolant during PCS boron concentration changes.

In additon, it is difficult to maintain PCS temperature <200°F, if the only method of core heat. removal is natural circulation.

SHUTDOWN COOLING (Continued)

3. l. 9 BASIS (Continued)

With the PCS temperature S200°F and the loops not filled, a single shutdown cooling train provides sufficient heat removal capability for removing decay heat.

To provide adequate mixing of the PCS coolant during PCS boron concentration changes, forced circulation is required during this operating condition except during intervals when the required trains can be intentionally rendered inoperable provided additional constraints are followed.

Single failure considerations, and the unavailability of the steam generators as a heat removing component, require that a second shutdown cooling train be operable.

. 300 All forced circulation may be isolated provided actions are t~o prevent dilution of the PCS and avoid situations that could produc~;;; *in the reactor vessel.

When the PCS temperature is >200°1 and <lii0 l, maintaining

~10°F subcooling ensures the availability of single phase natural circulation *. When the PCS temperature is S200°l, not exceeding 200°1 ensures the availability of a single phase natural circulation.

A redundant train of SDC may be intentionally rendered inoperable for testing or maintenance for any time interval provided the other SDC train is in operation.

No time limit is specified because the time interval that is needed fo each required evolution could vary.

This method of

~,

operating equipmen is consistent with the intent of Generic Letter 88-17, Loss of Decay Heat emoval. It is recommended that equipment be maintained and tested as appro riate to create an acceptable level of confidence that the systems will be ble to perform their decay heat removal function.

The ref ore, appropriat testing or maintenance is c.onsidered prudent and.

justified, without an specific time limit related to equipment that may be inoperable to permi such evolutions.

In all cases, the intent is to take reasonable actf ns to minimize the use of exception No. 1 of specification 3.1.9.c. If it is required, to use exception No. 1 of specification 3.1.9.c, SC will not be rendered inoperable in situations where PCS temperature is lose to i00°l or the PCS heatup rate would

\\

result in the PCS tempera re exceeding 200°1 in a relatively short period of time.
