20555 Gentlemen:
Joseph M. Farley Nuclear Plant - Units 1 and 2 NRC Bulletin No. 88-11 Pressuriur Surae line Thermal Stratification By letters dated January 31, 1991, Alabama Power Company submitted the results of the stress and fatigue analysis required by the subject bulletin for both units and a justification for continued operation (JCO) for Unit 2.
Nuclear Regulatory Commission (NRC) letter dated August 21, 1991, acknowledged receipt of our response and indicated that both units had satisfied the requirements of Bulletin 88-11.
This response also indicated that the JC0 submitted for Unit 2 is acceptable until such time as the leak-before-break (LBB) analysis review is completed by the NRC.
This implies that the JC0 acceptance is linked to the review of the LBB analysis. Alabama Power Company wishes to clarify that the JC0 on Unit 2 is not dependent on the approval of the LBB analysis.
As stated in the JC0 and restated in the NRC letter, a procedural change has been implemented to limit the system delta T to less than 3100F which will maintain the pipe stresses within the code allowable.
This conclusion is not based upon the LBB analysis.
Although it is Alabama Power Company's intent to remove the pipe whip restraints whenever the LBB analysis is approved, the JC0 would remain valid without the removal of the whip restraints.
The NRC letter requested that Alabama Power Company inform the NRC when all modifications to Unit 2 have been accomplished.
Notification will be made when Alabama Power Company has completed the modifications to the restraints.
The design is currently developed to the point that NRC approval is needed on the LBB analysis prior to proceeding.
If there are any questions, please advise.
Respectfully submitted, h
w sJ.
