Also, the Definitions in TS 1.1 are revised to include modifications and newly defined terms; the Limiting Conditions for Operation and associated Surveillance Requirements in TS 3.1 and 3.2 are revised; and editorial changes are made to TS 5.2 and 5.4. In the direct final rule, NRC stated that if no significant adverse comments were received, the direct final rule would become final on October 4, 2010. The NRC did not receive any comments on the direct final rule. Therefore, this rule will become effective as scheduled.Start Signature
