Dear Mr. Schwencer:

In order to support obtaining an operating license for Susquehanna SES Unit 2, attached is revised Section 7.1 of the Susquehanna SES FSAR. The revisions to this section are as follows:

New Section 7.1.2.6.9 has been added to provide a reference to the sections of the FSAR where compliance to Regulatory Guide 1.45 can be found.

7.1.2.6.9 These sections have been renumbered due to the insertion of through new Section 7.1.2.6.9.

7.1.2.6.20 7.1.2.6.21 This section has been added to provide a reference to our position on Regulatory Guide 1.97.

These revisions will be incorporated in the next amendment to the FSAR.

Very truly yours N. W. Curtis Vice President-Engineering t'onstruction-Nuclear Attachment cc: R. L. Perch NRC 8309200087 830916 PDR ADOCK 05000388

7.1.2.6.10 Conformance to Regulatory Guide 1.47 $ 5/73) a) NSSS The system of bypass indication is designed to satisfy the requirement of IEEE 279-1971 paragraph 4.13 and Regulatory Guide 1.47 and is discussed for each safety-related system under Sections 7.2, 7.3, 7.4, and 7.6. The design of the bypass indication system allows testing during normal operation and is used to supplement administrative procedures by providing indications of safety systems status.

The bypass indication system is designed and installed in a manner which precludes the possibility of adverse affects on the plant safety system. The bypass indication system is electrically isola+ed from the protection circuits such that the fa'lu"e or bypass of a protect've function is not a 'credible consequence of failures in the bypass indication system and the bypass indication system cannot reduce the independence be+ ween redundant safety systems.

b) Non-NSSS Refer to individual systems in Section 7.3 and discussion in Section 7.5

Equipment and components used for most acciden+. moni+orinq are described in the applicable FSA  ? sections.

7=1 ..2=7 Technical Design Bases The technical design bases for PPS are in Subsection 7. 2. 1, for enqineered safety featu"es in Subsection 7.3.1, for sys.ems required for safe shutdown in Subsection 7.4.1, and for other

~ys ems required fo" safety in Subsection 7.6.1.

7. 1. 2. 8 Sa fete System Settings The safety system setpoints are listed in the'echnical Soecifications. The settinqs are determined based on opera+'ng experience and conservative analyses. The settings are high enough to preclude inadvertant initiation of the safety action, but low enouqh to assure +hat siqnificant ma'rqin is maintained between the actual settinq and the limiting safety system
