y Steam Genitator Water Level,
The; Steam W erator Water Level Lew-Low trip protects the reactor from ioss of heat sitik in the events of'a sustained steam /feedwater flow mismatch resulting fr3m loss of normal feedwatav.
The specified Setpoint provides alloontes fos s' tarting delays of.the Auxiliary Feedwater System.
Steam /Feedwater Flow Misdatchland Low Steam Benerator Water Level TN Steam /F9edwate'r flow Nsmatch in coincidence with a Steam Generator Low War.er Leve %tnip is not used in the trnnsient and accident analyses but is included in Tame 2.2'1 to e'nsure the functional capability of the specified trip settings and therebysenbance, the'oYerall reliability of the Reactor Trip System.
This trip is redandant to'the Steam Generator Water Level Low-Low trip.
The Steam /Foc& ater-Flow Mismatch portion of this trip is activated when s
the steam flow-egceeds th'e 14edwater flow by greater than or equal to 1.45 x 10 6
'bs/hr for Un.i M and 1.49 ( 106 lbs/hr for Unit 2.
The Steam Generator Low Water level portion of the if fp' ig activated when the water level drops below 15%, as indicated by tue narrow ra.3ge instrument..These trip values include l
sufficient allowance in excess of normal operating' values to preclude spurious trips but will initiate a Reactor trip before the steam generators are dry.
Therefort(the required capacity and starting time requirements of the auxiliary feedwater pumps are reduced and the:Resulting thermal transient on the Reactor Coolant System and steam generators 9 minicized.
Undervoltage and Underfrequency - Reactor Coolant Pump Busses s
Tht'UnderWitage _and Underfrequency Reactor Coolant Pump Bus trips provide core proEe'ctior,",against DNB as a result of complete loss of forced coolant flow.
The specified'0etpoints assure a Reactor trip signal is generated before the Low Flow Trip Setpofnt is reached.
Time delays are incorporated in the Under-l frequendy and (Mdervoltage trips to prevent s prious Reactor trips from momen-l tary e10ctrical poder transients.
For undervoltage., the delay is set so that the time required for a' signal ?,o reach the Reactor trip breakers following the not exceed 0.h[ seconds. simultaneous t ip 16 two or mor6'reaEtor coolant pump bus circ For underfrequency, the delay is set so that the; time reqtired for a signal to reach the Reactor trip breakers after the Underfrequen-cy Trip Setpoint in reached shall not exceed 0.3 seconds.
On decreasing power, the Undervoltage dd Unddfrsquency Reactor Coolant Pump Bus trips are automa-tically blocked by 'P-7 (a power level of approximately 10% of RATED THERMAL POWER with a turbine impulse chamber pressure at approximately 10% of full power equivalents and on it. creasing power, reinstated automatically by P-7.
