REACTIVITY CONTROL SYSTEMS ACTION: (Continued)
- c. With a maximum of one demand position indicator per bank inoperable, either:
- 1. . Verify that all rod position indicators for the affected bank are OPERABLE and that the most withdrawn rod and the least withdrawn rod of the bank are within a maximum of 16 steps of each other imediately after rod motion greater than 8 steps (greater than 16 steps if all rods in the group have been determined to be within 8 steps of the group demand indicator by voltage measurements within the previous 4 hours4.62963e-5 days <br />0.00111 hours <br />6.613757e-6 weeks <br />1.522e-6 months <br />) and at least once per 8 hours9.259259e-5 days <br />0.00222 hours <br />1.322751e-5 weeks <br />3.044e-6 months <br />, or 2..

- d. If the position of more than one rod cannot be detennined by either the direct reading of the rop position indicators or by reading primary detector voltage measurements, then Specification 3.0.3 is applicable.
SURVEILLANCE REQUIREMENTS 4.1. 3. 2 Each-rod position indicator channel shall be determined to be
. OPERABLE by verifying the demand position indication system and the rod position indicator channels agree within 16 steps at least once per 12 l hours (except during time intervals when the Rod Position Deviation Monitor is INCPERABLE or is in a continuous state of alarm), then compare the demand position indication system and the rod position indicator channels at approximately 4 hour4.62963e-5 days <br />0.00111 hours <br />6.613757e-6 weeks <br />1.522e-6 months <br /> intervals, as follows:
- a. If an individual rod position indicator analog channel does not settle to within + 16 steps within 1 hour1.157407e-5 days <br />2.777778e-4 hours <br />1.653439e-6 weeks <br />3.805e-7 months <br />, then declare that l channel INOPERABLE. ,
- b. For any INOPERABLE channel, no repairs or adjustments shall .
be permitted.without being followed immediately by a full range calibration.

- For Core PHYSICS TESTING in Mode 2, primary detector voltage' measurements may be used to detennine the-position of rods in shutdown banks A and B and control banks A and B for the purpose of satisfying Specification 3.1.3.2. During Mode 2 operations, _ rod position indicators for shutdcwn banks A and B and control banks A and B may deviate from the group demand indicators by greater than + 16 steps during reactor startup 'l and shutdown operations, while rods are being withdrawn or inserted.
If the rod position indicators for shutdown ~ banks A and B and control banks A and B deviate by greater than + 16 steps from the group demand l P. ~
indicator, rod withdrawal or insertion may continue until the desired group height is achieved.
