RPS Instrumentation 3.3.1 Table 3.3.1-2 (page 1 of 1)

Thermal Margin/Low Pressure Trip Function Allowable Value The Allowable Value for the Thermal Margin/Low Pressure Trip, Pt. p, is the higher of two values, Pmrn and Pvar, both In psia:

Pmin = 1750 Pvar =.2012(QA)(QRj) + 17.0(Tin) - 9559 I

Where:

QA = - 0.720(ASI) + 1.028; QA = - 0.333(ASI) + 1.067; QA = + 0.375(ASI) + 0.925; ASI = Measured ASI ASI = 0.0 QR1 = 0.412(Q) + 0.588; QRj = Q; when - 0.628 *ASI < - 0.100 when - 0.100 *ASI < + 0.200 when + 0.200

• ASI * + 0.565 when Q 2 0.0625 when Q < 0.0625 when Q s 1.0 when Q > 1.0 Q = THERMAL POWER/RATED THERMAL POWER Tin = Maximum primary coolant Inlet temperature, in 'F ASI, Tin, and Q are the existing values as measured by the associated instrument channel.
