Inaccordance withthescheduleprescribed bytheNuclearRegulatory Commission (NRC)andtheFederalEmergency Management Agency(FEMA),the1995emergency exercisewillbeconducted asadayshiftexercise.

Exerciseeventswillbeginatapproximately 0800onMay9,1995initiating themobilization ofCookNuclearPlant,AmericanElectricPowerNuclearOrganization (AEPNO),andIndianaMichiganPowerCompany(I&M)personnel.

H.Controller ObserverGuidelines Controllers andObservers areutilizedinthisexercisetoprovideexerciseinformation totheparticipants andtoobserveplayersresponse.

Indoingso,theControllers andObservers shouldallowplayerstomake,andcorrect,theirownmistakes, whiletheController orObserveridentifies theitemstoimprovePlantemergency responsecapability.

-However,situations mayarisewherecompletefreedomofplayerresponseandsuccessoftheoverallexerciseareconflicting objectives.

Insuchcases,theController orObservermustensurepropercontinuity ofthescenario, whileidentifying problemareasinsufficient detailtoallowcorrections.

Generally, thefollowing rulesapplytocontroloftheexercise:

1.'Keepthereactionandemergency responsegoingaccording tothetimeelementestablished inthescenario.

2.Providecommandmessagestokeypersonnel asamechanism topreventdeviation fromthescenario.

3.Observeplayerprocedural discipline.
