Refueling Equipment Interlocks B 3.9.1 BASES (continued) l APPLICABILITY In MODE 5. a prompt reactivity excursion could cause fuel damage and subsequent 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 MODES 1. 2, 3. and 4. the reactor pressure vessel head is on, and no fuel loading activities are possible. Therefore, the refueling interlocks are not required to be OPERABLE in these MODES.

i l

l ACTIONS A.1. A.2.1. and A.2.2 With one or more of the required refueling equipment interlocks inoperable, the unit must be placed in a condition in which the LC0 does not apply or the Surveillances are not needed. This can i

be performed by ensuring fuel assemblies are not moved in the reactor vessel or by ensuring that the control rods are inserted and can not be withdrawn.

Therefore. Required Action A.1 requires that in-vessel fuel movement with the affected refueling equipment must be immediately suspended. This action ensures that operations are not performed with equipment that would potentially not be blocked from unacceptable operations (e.g., loading fuel into a cell with a control rod withdrawn). Suspension of in-vnsel fuel movement shall not preclude completion of movement of a component to a safe position.

Alternatively. Required Actions A.2.1 and A.2.2 require that a control rod withdrawal block be inserted and that all control rods subsequently verified to be fully inserted. Required Action A.2.1 ensures that no control rods can be withdrawn. This action ensures that control rods cannot be inappropriately withdrawn because an electrical or hydraulic block to control rod withdrawal is in place. Required Action A.2.2 is performed after placing the rod withdrawal block in effect and provides a verification that all rods in core cells containing one or more fuel assemblies are fully inserted. The allowance to not verify that control rods associated with defueled cells are inserted is

B 3.9.1 BASES ACTIONS to allow control rods to be withdrawn in accordance with (continued)

LCO 3.10.6 while complying with these actions. This verification that all required control rods are fully inserted is in addition to the periodic verifications required ty SR 3.9.3.1 and SR 3.10.5.2.

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.)

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 required condition is injected into the logic. The CHANNEL FUNCTIONAL TEST may be performed by any series of sequential, overlapping, 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 interlocks and their associated input status that are available
