Methods for review and evaluation of emergency-procedure guidelines. Volume II. Applications to Westinghouse plants. [PWR]

Technical Report ·
OSTI ID:6487568
Systematic methods for finalizing, reviewing, or developing improved emergency-procedure guidelines are applied to a Westinghouse PWR plant. The methods are based on the use of operator action event trees (OAETS) which document the key operator actions and plant symptoms associated with the various stages of risk-significant multiple-failure accident sequences. The application of the methodology utilizes OAETS developed for the Zion 1 PWR and the Westinghouse Owners Group's Emergency Response Guidelines. Since the details of the Westinghouse Function Restoration Guidelines (FRGs) were not yet complete, this examination did not take the form of an evaluation of the correctness or completeness of the final guidelines. Rather, the product of this examination was a delineation of the necessary characteristics which each FRG must possess when it is developed in complete detail.
