SAFETY LIMITS AND LIMITING SAFETY SYSTFM SETTINGS 2.2 LIMITING SAFETY SYSTEM SETTINGS REACTOR TRIP SYSTEM INSTRUMENTATION SETPOINTS 2.2.1 The Reactor Trip System Instrumentation and Interlock Setpoints shall be set consistent with the Trip Setpoint values shown in Table 2.2-1.

APPLICABILITY: As shown for each channel in Table 3.3-1.

ACTION:

a. With a Reactor Trip System Instrumentation or Interlock Setpoint less conservative than the value shown in the Trip Setpoint column but more conservative than the value shown in the Allowable Value column of Table 2.2-1, adjust the Setpoint consistent with the Trip Setpoint value,
b. With the Reactor Trip System Instrumentation or Interlock Setpoint less conservative than the v&lue shown in the Allowable Value column of Table 2.2-1, either:
1. Adjust the Setpoint consistent with the Trip Setpoint value of Table 2.2-1 and determine within 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br /> that Equation 2.2-1 was satisfied for the affected channel, or
2. Declare the channel inoperable and apply the applicable ACTION statement requirement of Specification 3.3.1 until the channel is restored to OPERABLE status with its Setpoint adjusted consistent with the Trip Setpoint value.

Equation 2.2-1 Z + R + 51 TA Where:

Z = Tne value from Column Z of Table 2.2-1 for the affected channel, R = The "as measured" value (in percent span) of rack error for the affected channel, S = Either the "as measured" value (in percent span) of the sensor error, or the value from Column 5 (Sentor Error) of Table 2.2-1 for the affected channel, and TA = The value from Column TA (Total Allowance) of Table 2.2-1 for the affected channel.

$URVEILLANCE REQUIREMENTS 4.4.1.4.1.1 The secondary side water level of at least two steam generators when required shall be determined to be within limits at least once per 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br />.

4.4.1.4.1.2 At least one RHR loop shall be determined to be in operation and circulating reactor coolant at least once per 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br />.

  • The RHR pump may be deenergized for up to I hour provided: (1) no operations are permitted that would cause dilution of the Reactor Coolant Systee boron concentratien and (2) core outlet temperature is maintained at least 10*F below saturation temperature.
    • 0ne RHR loop may be inoperable for up to 2 hours2.314815e-5 days <br />5.555556e-4 hours <br />3.306878e-6 weeks <br />7.61e-7 months <br /> for surveillance testing provided the other RHR loop is OPERABLE and in operation.
      • A reactor coolant pump shall not be started unless the secondary water temperature of each ste'an generator is less than 50*F above each of the Reactor Coolant System cold leg temperatures.

APPLICABILITY: MODE $ 1, 2, 3, and 4.

ACTION: l i

With the structural integrity of the containment vessel not conforcing to the  ;

above requirements, restore the structural integrity to within the limits prior to increasing the Reactor Coolant System temperature above 200'F.

SURVE!LLANCE REQUIREMENTS 4.6.1.6 The structural integrity of the containment vessel shall be determined I during the shutdown for each Type A containment leakage rate test (reference ,

Specification 4.6.1.2) by a visual inspection of the exposed accessible interior and exterior surfaces of the vessel. This inspection shall be performed prior totheTypeAcontainmentleakageratetesttoverifynoapparentchangesin ,

appearance of the surfaces or other abnormal degradation. Any abnorma degrada-tion of the containment vessel detected during the above required inspections shall be reported to the Commission in a $pecial Report pursuant to $pecift- f cation 6.8.2 within 15 days. ,
