. LIMITING CONDITIONS FOR OPERATION t
2.1 Thermal 2.1.1 Maximum AT Across Condenser 3
Objective To limit thermal stress to the aquatic ecosystem by limiting the 1
maximum AT across the condenser during operation.
4-i Specification:
a.
The maximum differential temperature across the condenser shall not exceed 15'F during normal operation with all four circulating l
water pumps in operation.
b.
If one or two circulating water pumps are out of service at any given time the maximum condenser AT shall not exceed 30*F; and Specification 2.1.2 of this Appendix shall be met.
Monitoring Requirement The temperature differential across the condenser shall be monitored every hour utilizing the computer output of the condenser inlet and y
outlet temperature measurements.
The range of these measurements shall be 0-150*F and their accuracy shall be 0.5%.
If the plant computer is inoperable and until the condenser outlet-temperature sensor is relocated in the discharge canal, the condenser AT shall be monitored at least once each shift when the plant y
,is operating at steady state power levels.
The condenser AT shall be i
measured within two (2) hours af ter a change in power level has been.
stabilized 'and at least once each shif t thereafter.
The condenser AT i
shall be determined using measurements at the condenser inlet and in the discharge canal.
Bases Maximum AT's of 15*F with 4 circulating water pumps operating
(%1700 cfs flow). and 30?F -with 2 circulating water pumps. operating will: insure that the limits of the applicable water quality criteria will not be exceeded. The difference in temperature readings of the RTD's at the inlet and outlet of the condensers provides the AT across J
)
the condensers.
Specification 2.1.1'.b allows maintenance to be performed on circulating
' water pumps when the Dardanelle Reservoir ambient temperature is such that Specification :2.1.2 will not be exceeded. Hydraulic model studies have shown that a 30*F AT at 850 cfs circulating waterflow will not result -in adverse' changes in the Dardanelle Reservoir isothenns when
~).
2-2 compared-to the isotherms resulting from a 15'F AT at 1700 cfs except on the surface of the discharge embayment.
2.1.2 Maximum Discharge Temperature Obiective L
To limit thermal stress to the aquatic ecosystem by limiting the plant's maximum discharge water temperature.
Specification The condenser discharge water temperature shall not exceed 105*F for more than two consecutive hours.
If the water temperature exceeds 105*F for two hours an investigation of the situation will be undertaken and corrective action shall be taken to main-l tain the discharge water temperature at 105*F or less. One such corrective action would be a reduction in the plant power level unless there is an emergency need for the lost power. This emergency need would exist when a reduction in power would mean cutting off firm customers.
If monitoring (see below) indicates that the temperature at the mouth of the discharge embayment is j$ 105'F, the plant load will not be reduced.
Monitoring Requirements p
Condenser discharge water temperature shall be monitored every hour
^
utilizing the average of the computer output of the condense: dis-charge RTD readings.
The RTD's have a 0-150*F range and an accuracy of i0.5%.
If the plant computer is inoperable and until the condenser outlet temperature sensor is relocated in the discharge canal, the
- condenser discharge temperature shall be measured at least once each 1
shift.
If the condenser inlet temperature exceeds 85'F with all four circulating water pumps running or 70*F with less than four circulating water pumps running, the condenser outlet temperature shall be monitored every two (2) hours.
If the condenser discharge water temperature exceeds 105*F, plant personnel will be dispatched to the mouth of the discharge embay-ment to monitor the exit temperature from the embayment.
Monitoring of the embayment will continue every two hours as long as the con-denser outlet temperature remains at 105*F.
Bases 4
\\
The 105'F maximum discharge water temperature limit is set to assure that the Dardanelle Reservoir temperature does not exceed t
