SPECIAL TEST EXCEPTIONS BASES 6

3/4.10.8 CONTROL ROD PROGRAM CONTROLS h

With the in plant demonstration of a fine motion control rod drive (FMCRD) installed at the peripheral location 02-43 during the second fuel cycle, position 02-43 will be bypassed in the Rod Sequence Control System (RSCS) and programmed out of the Rod Worth Minimizer-(RWM).

This will free the FMCR0 rod from the Banked Position Withdrawal Sequence (BPWS) and notch movement

' restrictions.

By requiring that thermal power be greater than 25% rated thermal power and a rod pattern be established (after the withdrawal / insert sequences of its Banked Position Withdrawal Sequence Group are complete) l before movement of control rod 02-43, one ensures that this rod will be moved j

only under conditions when the RSCS and RWM are not required to be operable.

After one cycle of demonstration with this control rod, position 02-43 will be returned to the RSCS and RWM in conjunction with the reinsta11ation of the original locking piston control rod.

3/4.10.9 SHUTDOWN MARGIN With the in plant demonstration of a fine motion control and rod drive installed at 02-43 during the second fuel cycle, the shutdown margin shall be i

. demonstrated-assuming this control rod is at the fully withdrawn position.

In 4

other words, during the second fuel cycle, the shutdown margin shall be equal to or greater than the values specified in Specification 3.1.1 with the most l

reactive control rod and the fine motion control rod fully withdrawn.

3/4.10.10 CONTROL R00 i

A fine motion control rod drive will be installed at LaSalle County Station Unit-2 during the second fuel cycle.

To minimize the safety impact, a peri-pheral location 02-43 is selected. 'Due to the temporary test nature of this control rod drive, safety evaluation has been performed to justify continued safe operation of the reactor assuming this control rod drive is inoperable.

i-However, this rod is not considered inoperable in the context of specifications

)

3.1.3.1 through 3.1.3.7 and any scram time will not be included in I,y, in specification 3/4.2.3. Thus during the second duel cycle operation the LCO and l-surveillance requirements applicable to regular control rods are exempted for i

this control rod.

After one cycle of demonstration, this control rod drive i

will be removed and the original locking piston control rod drive will be reinstalled at this location.
