- Section 2.1 Transients Analyzed
- Section 2.P Analysis Approach and Documentation Section 2.1 Transient Results Section 2. ! ATKS Perfonrance Indices .
- Section 2.6 Comparison of Predicted Plant Behavior with ATWS Ferfont.ance Indices, and
- Sectio 3B, Functional Requirements; Items B.1 (Function) B.2 (Inp n), b.8 (Startup Byp:ss), B.9 (Trip Setpcint).
The enclosed safety evaluation indicates that the generic functional requirements contained in the sections listed above are acceptable. Licensees referencing these requirenents will, bewever, be required to justify the selection of DSS input from several alternatives contained in the generic requirements This review was performed by W.
