APPLICABILITY:
As shown in Table 3.3.3-1.
ACTION:
a.
With an ECCS actuation instrumentation cnannel trip setpoint less i
conservative than the value shown in the Allowable Values column of Table 3.3.3-2, declare the channel inoperable until the channel is restored to OPERABLE status with its trip setpoint adjusted consistent with the Trip Setpoint-value.
b.
With one or more ECCS actuation instrumentation channels inoperable, take the ACTION required by Table 3.3.3-1.
c.
With either ADS trip system "A" or "B" inoperable, restore the inoperable trip system to OPERABLE status:
I 1.
Within 7 days, provided that the HPCS and RCIC systems are OPERABLE, or 2.
Within 72 hou'rs, provided either the HPCS or the RCIC system is inoperable.
Otherwise, be in at least HOT SHUTDOWN within the next 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br /> and reduce reactor steam dome pressure to less than or equal to 100 psig within the following 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br />.

By verifying that each of the required RHR pumps develops a flow of at least 5050 gpm on recirculation flow through the RHR heat 4
exchangers to the suppression pool when tested pursuant to Specifi-cation 4.0.5.
- Whenever both RHR loops are inoperable, if unable to attain COLD SHUTOOWN as required by this ACTION, maintain reactor coolant temperature as low as practical by use of alternate heat removal methods.
