DOCKET NOS. 50-445 AND 50 146 FSAR AMENDMENT 87 DESCRIPTION Gentlemen:

Amendment 87 to the CPSES FSAR was transmitted to you under a separate cover letter TXX-92568, dated December 18, 1992. The attachment to this letter provides line-by-line descriptions of the changes in Amendment 87. FSAR pages which do not have technical changes but are included in the amendment (because they are the opposite side of the sheet from a page that was changed, because the change shifted the existing material to another page or because only editorial changes were made on these pages) are not discussed in the attachment.

As has been the TU Electric practice in past FSAR amendments, all changes described in the attachment have been evaluated for relative significance (i.e., the group number 1, 2, 3 or 4 following each change justification as discussed in TV Electric letter TXX-88467 dated June 1, 1988). In addition, all changes applicable to CPSES Unit 1 have been reviewed under the TU Electric 10CFR50.59 process and were found not to include any "unreviewed safety questions."

Amendment 87 includes the following change'. which were previously transmitted to the NRC as advance FSAR submittals or which have resulted from NRC Requests forAdditionalInformaten(RAI):
