o 3.1.3.2 The shutdown and control rod position indication system shall be OPERALLE as follows:

Group Demand CounterII), 1 per group Individual analog rod position instrument channel, 1 per rod + 12 steps (l) accuracy (3) l Automatic Rod Position Deviation Monitor (2), setpoints g 12 steps, or, setpoint verification by recording analog / digital rod position at least once per 4 hours4.62963e-5 days <br />0.00111 hours <br />6.613757e-6 weeks <br />1.522e-6 months <br />.

The provisions of Specification 3.0.4 are not applicable to this monitor (3).

(1)

During the first hour following rod motion, the group demand counter is the primary indicator of precise rod position infor-mation, with the analog channels displaying general rod movement information.

For power levels below 50%, a 1-hour thermal soak time is allowed before the analog chann'els are required to.per-form within the specified accuracy.

(2)

For power levels below 50% a one hour thermal soak time is 3

allowed.

Therefore, if a Rod Position Deviation Monitor alarm clears itself within this hour, the alarm is considered invalid.

l (3)

The reporting requirements of Specification 6.9.1.9 are not i

applicable for the group demand counters, analog RPI or Rod Deviation Monitor providing that no actual rod misalignment existed due to the malfunction.

These malfunctions shall be reported in the monthly operating report.
