APPLICABILITY In H00E 5, a )rompt reactivity excursion could cause fuel l

! damage and su) sequent release of radioactive material to the

. environment The refueling equipment interlocks protect against prompt reactivity excursions during MODE 5. The interlocks are only required to be OPERABLE during in-vessel fuel movement with refueling equipment associated with the interlocks.

In H00ES 1, 2, 3, and 4. the reactor pressure vessel head is installed..and no fuel loading activities are possible. -

' Therefore, the refueling equipment interlocks are not required to be OPERABLE in these MODES.

ACTIONS A. ( A .2. 1, wJL h. z 2- str+

With one or more of the required refuelin ipment interlocks ino)erable, the unit must be p ,1 in a condition in w11ch the LCO does not apply. 4-vessel fuel movement with the affected refueling equi it must be imediately suspended. This action ensures that operations 1

j SURVEILLANCE SR 3.9.1.1 REQUIREMENTS Performance of a CHANNEL FUNCTIONAL TEST demonstrates each required refueling equipment interlock will function properly when a simulated or actual signal indicative of a recuired condition is injected into the logic. The CHANNEL FUhCTIONAL TEST may!be performed by any series of sequential, overlal) ping, or total channel steps so that the entire channel is tested. >

The 7 day Frequency is based on engineering judgment and is considered adequate in view of other indications of refueling equipment interlocks and their associated input.

• - Attachment 4 PY-CEl/NRR-2418L l Page 2 of 2 Insert A to Paae B 3.9-3 or the Surveillances are not needed. This can be performed by ensuring fuel assemblies are not moved in the reactor vessel or by ensuring that the control rods are inserted and cannot be withdrawn.

Therefore, Required Action A.1 requires that insert B to Pane B 3.9-3 Altematively, Required Actions A.2.1 and A.2.2 require that a control rod withdrawal block be inserted and that all required controls rods are subsequently verified to be fully inseded. Required Action A.2.1 ensures that no control rods {

can be withdrawn. This action ensures'that control rods cannot be inappropriately withdrawn because an electrical or hydraulic block to control rod withdrawalis in place. Required Action A.2.2 is performed after placing the rod withdrawal block in effect, and provides atverification that all rods in core cells containing one or more fuel assemblies are fully inserted. The requirement that control rods need only be inserted in core cells containing one or more fuel assemblies is to allow control rods to be withdrawn in accordance with LCO - 3.10.6 while complying with these LCO 3.9.1 Required Actions. This verification that all required control rods are fully inserted is in addition to the periodic verifications required by SR 3.9.3.1 and SR 3.10.6.2. Like Required Action A.1, Required Actions A.2.1 and A.2.2 ensure that unacceptable operations are blocked (e.g., loading fuel into a cell with the control rod withdrawn),
