DESCRIPT!ON OF PROCESS FOR DEVEL W 4NG EMERGENCY OPERATION INFOR'MTION AND CONTROLS FOR GIAPTER 18 APPENDIX 18F.

• e, a +

. An analysis of operator control and informadon needs is performed based upon the ABWR EPGs as given in Appendix lBA and based upon the results of analysis of important operator actions in the PRA. "The analysis results is documented in Appendia 18F in the form of tables. A table is used for each EPG step or PRA-important opera action as described below:
