a.

In OPERATIONAL CONDITION 2* with one of the above required source _

range monitor channels:inoptrable, restore at least 3 source range-monitor channels to OPERABLE status within 4 hours4.62963e-5 days <br />0.00111 hours <br />6.613757e-6 weeks <br />1.522e-6 months <br /> or 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 />, b.

In OPERATIONAL CONDITION 3 or 4 with one or more of-the above required

' source range monitor channels _ inoperable, verify all insertable con-trol rods to be fully inserted in the core and lock the' reactor mode switen in the Shutdown position within one hour.

I INSTRUMENTATION TRAVERSING IN-CORE PROBE SYSTEM-LIMITING CONDITION FOR OPERATION 3.3.7.7 e traversing in-core probe system'shall be OPERABLE with either:

a.

<ive movable. detectors, drives and readout equipment to map the core, and indexing equipment to allow all five detectors to be calibrated in a common location.-

OR b.

. ith one or more TIP measurement locations inoperable, data may be~-

W replaced by data obtained from-that location's-symmetric counterpart i

if the substitute TIP data was"obtained from an'0PERABLE measurement -

location; provided the reactor core is-operating in a type A control rod pattern and the total core TIP uncertainty for the present cycle ~

3 has been determined.to be less than 8.7 percent (standard deviation).

Symmetric counterpart data may be substituted for a maximum of-ten; TIP measurement locations.

i i

APPL ICABILITY: When the traversing in-core probe is used for:

a.*

Recalibration of the LPRM detectors, and b.*

Monitoring the APLHGR, LHGR, or MCPR.

l ACTION:

l With the traversing ~ 1n-core probe system inoperable 'do= not' use the system for the above applicable monitoring or. calibration functions. -The provisions'of-L Specification 3.0.3 are not applicable.
