. 2.0 LIMITING CONDITIONS FOR OPERATION 2.14 Engineered Safety Features System Initiation Instrumentation Settings Applicability Applies to the engineered safety features system initiation instrumentation settings.
Objective To provide for automatic initiation of the engineered safety features in the event that principal process variable limits are exceeded.
Specifications The engineered safety features system initiation instrumentation setting limits shall be as stated in Table 2-1.
Basis (1) High Containment Pressure The basis for the 5 psig set point for the high pressure signal is to establish a setting which would be exceeded quickly in the event of a DBA, cover a spectrum of break sizes, and yet be far enough above normal operation maximum internal pressure to prevent spurious initiation.
High containment pressure initiates the steam generator isolation signal which will close the main steam isolation and bypass v&lves and the main feedwater isolation and bypass valves.
(2) Pressurizer Low Pressure The pressurizer low pressure safety injection signal is a diverse signal to the high containment pressure safety injection signal.
The 1600 psia setting includes an uncertgipty of + 22 psia and is the setting used in the safety analysis.t li (3) Containment High Radiation (Air Monitoring)
The containment air monitoring system comprises a moving paper filter particle monitor (channel RM-050) and a sample chamber gas monitor (channel RM-051) installed in a comon housing.(2)
Optionally, the sampling point for channels RM-050 and RM-051 can be switched from the containment to the ventilation discharge duct.
The ventilation discharge monitoring system consists of a moving l paper filter particle monitor (RM-061) and a sample chamber gas '
monitor (RM-062) installed in a comon housing. An iodine monitor for I-131 (RM-060) also monitors these releases.

(3) ContainmentHighRadiation(AirMonitoring) (Continued)
The setpoints for the isolation function will be calculated in accordance with the ODCM.
Each channel is supplied from a separate instrument A.C. bus <
and each auxiliary relay requires power to operate. On failure of a single A.C. supply, the A and B matrices will assume a one-out-of-two logic.
(4) Low Steam Generator Pressure A signal is provided upon sensing a low pressure in a steam generator to close the main steam isolation valves in order to minimize the temperature reduction in the reactor coolant system with resultant loss of water level and possible addition ,
of reactivity. The setting of 500 psia includes a +22 psi i
uncertainty and was the setting used in the safety analysis.(3)
Closure of the MSIVs (and the bypass valves, along with main feedwater isolation and bypass valves) is accomplished by the steam generator isolation signal which is alggicalycombleation of low steam generator pressure or high containment pressure.
As part of the AFW actuation logic, a separate signal is provided to terminate flow to a steam generator upon sensing a low pressure in that steam generator if the other steam generatcr pressure is greater than the pressure setting. This is done to minimize the temperature reduction in the reactor coolant system in the event of a main steamline break. The setting of 466.7 psia includes a +31.7 psi uncertainty; therefore, a setting of 435 psia was used in the safety analysis.
(5) SIRW Tank Low Level Level switches are provided on the SIRW tank to actuate the valves in the safety injection pump suction lines in such a manner so as to switch the water supply from the SIRW tank to the containment sump for a recirculation mode of operation after a period of approximately 24 minutes following a safety injection signal. The switchover point of 16 inches above tank bottom is set to prevent the pumps from running dry during the 10 seconds required to stroke the valves and to hold in reserve approximately 28,000 The FSAR lossgallons of ataccident of coolant least 1800 ppm (4) analysis borated water.

(6) Low Steam Generator Water Level As part of the AFW actuation logic, a signal is provided to initiate AFW flow to one or two steam generators upon sensing a low water level in the steam generator (s) if the absolute steam generator pressure criteria are satisfied. This function ensures adequate steam generator water level is maintained in the event of a failure to deliver main feedwater to either steam generator. The setting of 28.2% of wide range tap span includes a +13.2% uncertainty; therefore, a setting of 15% of wide range tap span was used in the safety analysis.
(7) High Steam Generator Delta Pressure As part of the AFW logic, a high steam generator differential pressure signal is generated to provide AFW to the higher pressure steam generator with a concurrent low level signal if both steam generator pressures are less than 466.7 psia.
If the differential pressure between steam generators is less than the setting, neither steam generator is supplied with AFW in the presence of a low level signal. The setting of 119.7 psid includes a -15.3 psi uncertainty; therefore, a setting of ,
135 psid was used in the AFW safety analysis.
