This letter modifies the l; wording of the requested change to Limiting Condition for Operation 3.3.2 l ACTION b.-

The wording of the ACTION b proposed in Reference 1 is justified by the analysis of References 1, 2, 3, and 4. However, subsequent discussions with the NRC revealed that raview and approval of the change would be expedited by modifying the proposed wording to correspond with the example ACTION requirement provided in Reference 2.
