Validation of EOPs/FRGs Procedures Using LOHS Scenario

Validation of EOPs (Emergency Operating Procedures) and FRGs (Function Restoration Guidelines) can be achieved either through plant full scope simulator or on desk top exercises. The exercise is conducted when for the given scenario not suitable. In verification cases predefined should evaluated possible branching foreseen. presented LOHS, with bleed feed procedure initiated. Best estimate light water reactor transient analysis code RELAP5/mod3.3 was used in calculation. Standardized detailed model used. Operator actions were modelled from beginning to its termination.
