APPLICABILITY Operation in MODE 5 is controlled by existing LCOs. The exceptions from other LCO requirements (e.g., the ACTIONS of LC0 3.9.3, LC0 3.9.4 or LCO 3.9.5) allowed by this Special Operations LC0 are appropriately controlled by requiring all fuel to be removed from cells whose " full in" indicators are

! allowed to be bypassed.

! restore operation consistent with the normal requirements for refueling (i.e., all control rods inserted in core cells containing one or more fuel assemblies) or with the exceptions granted by this Special Operations LCO.

2 INSERT B 3.10-27A i SR 3.10.6.3 and SR 3.10.6.4 SR 3.10.6.3 and SR 3.10.6.4 provide alternate methods of meeting the requirements of LCO 3.10.6.c when loading fuel assemblies (loading includes incore fuel shuffle since the j fuel assembly beira moved must be loaded 'eto the new position). Each of these  :

surveillances are to ensure the periodic verification of the administrative controls  !

established by this Special Operations LCO to preclude the possibility of an inadvertent criticality.

SR 3.10.6.3 requires the compliance to an approved spiral reload sequence whenever  ;

control rod (s) are withdrawn or removed in accordance with this LCO and the possibility '

exists that fuel assemblies could be loaded in to a core cell with withdrawn or removed )

control rod (s). SR 3.10.6.3 requires that when loading fuel into the core with multiple control rods withdrawn, special spiral reload sequences are used to ensure that reactivity additions are minimized. - Spiral reloading encompasses reloading a cell (four fusl beations immediately adjacent to a control rod) on the edge of a continuous' fueled region (the cell can be loaded in any sequence). This SR in not required to be met when SR 3.10.6.4 is satisfied for LCO 3.10.6.c.2 requirements.

SR 3.10.6.4 provides an alternate method to assure that an unacceptable reactivity addition does not occur during fuel loading when control rod (s) are withdrawn or removed in accordance with this LCO. As a backup to refueling procedures this surveillance verifies the LCO 3.10.6.c.2 requirement that a positive means of assuring fuel assemblies cannot be loaded into a core cell with a withdrawn or removed control rod is in effect. The positive means entails a physical barrier such that even if refueling procedures were violated and an attempt was made to load a fuel assembly into a core cell with a withdrawn or removed control rod the action would be prevented. This requirement provides sufficient additional restrictions considering the plant condition because with no fuel assemblies in the core cell, the associated control rod has no reactivity control function and any fuel loading error other than loading the fuel assembly into a core cell with a withdrawn or removed control rod is bounded by the analyzed fuel assembly mispositioning events. This SR is not required to be met when SR 3.10.6.3 is satisfied for LCO 3.10.6.c.1 requirements.

Tne 24 hour2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> Frequency of these surveillance is acceptable, given the administrative controls on fuel assembly and control rod removal, and takes into account other indications of control rod status available in the control room.
