APPLICABillTY:

As shown in Table 3.3-3.

ACTION:

With an ESFAS Instrumentation or Interlock Trip Setpoint less conserva-a.

tive than the value shown in the Trip Setpoint column but more conser-vative than the value shown in the Allowable Value column of Table 3.3-4. adjust the Setpoint. consistent with the Trip-Setpoint value.

b.

With an ESFAS Instrumentation or Interlock Trip Setpoint less conser-vative than the value shown in the Allowable Values column of Table 3.3-4, either:

1.

Mjust the Setpoint consistent with the Trip Setpoint value of j

restored to OPERABLE status with its Setpoint adjusted consistent 1

(

with the Trip Setpoint value.

Where:

2

= The value from Column 2 of Table 3.3-4 for the af fected 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 (Sensor Error) of i

Table 3.3-4 for the affected channel, and 1

TA = The value from Column TA (Total Allowance) of Table 3.3-4 for the affected channel, 1

I the ACTION shown in Table 3.3-3.

SURVEILLANCE RE0UIREMENTS 4.3.2.1 Each ESFAS instrumentation channel and interlock and the automatic actuation logic and relays shall be demonstrated OPERABLE by the performance of the ESFAS Instrumentation Surveillance Requirements specified in Table 4.3-2.

4.3.2.2 The ENGINEERED SAFETY FEATURES RESPONSE TIME of eacn ESFAS function snall be demonstrated to be within the limit at least once per 18 months.

Each

(

test shall include at least one train such that both trains are tested at least once per 36 months and on2 channel per function such that all channels are tested at least once per N times 18 months where N is the total number of redundant channels in a specific ESFAS function as shown in the " Total No. of Channels" Column of Table 3.3-3.
