-Thisevaluation taskinvolvestwo.subtasks: | |||
verification ofinstrument/control availability, andverification ofHumanEngineering suitability. | |||
Thefirst,verification ofavailability, isconducted usingthetaskanalysisandControlRoominventory. | |||
Ingeneral,tasksassociated withControlRoom'unctions areexaminedintermsofappropriate instrumentation intheControlRoom(ie.,taskequipment demandsvs.actualequipment presenceintheControlRoom).Oncethis.isaccomplished, estimates ofthefrequency-of-use forallinstrumentation aregenerated | |||

Also,tasksequences requiredinselectedeventsequences areestimated astofrequency ofoccurrence in'theeventsequences. | |||
Comparing bothfrequency andrequirements datatotheinventory, identification ismadeof:1)therabsence(intheControlRoom)oftaskrequiredinformation orcontrol,2)theestimated frequency with,whichtheinformation orcontrolisrequired, and3)theconditions (events,procedures, etc.)underwhichtheinformation orcontrolisrequired. | |||
Basedontheabove,HEDsareidentified anddocumented. | |||

1.2.2.2AssembleControlRoomDocumentation
-Inthistask,aControlRoomdatabaseisestablished tosupportthesubsequent evaluation.

ThelibraryandphotoMocumentation arecentrally locatedtosupportthe,effort.Inadditiontothelibraryandphotographic documentations, aControlRoominventory ofcomponents isdeveloped, identifying foreachcomponent, itslocation, systemrelationships, functions, andcharacteristics.

-Thisevaluation taskinvolvestwo.subtasks:
verification ofinstrument/control availability, andverification ofHumanEngineering suitability.
Thefirst,verification ofavailability, isconducted usingthetaskanalysisandControlRoominventory.
Ingeneral,tasksassociated withControlRoom'unctions areexaminedintermsofappropriate instrumentation intheControlRoom(ie.,taskequipment demandsvs.actualequipment presenceintheControlRoom).Oncethis.isaccomplished, estimates ofthefrequency-of-use forallinstrumentation aregenerated
.for:oStartupoShutdownoChangeofreactorpower.Estimations ofnon~rocedurally boundoperations (e.g.,boration, etc.)aregenerated viaoperatorinterviews.
Also,tasksequences requiredinselectedeventsequences areestimated astofrequency ofoccurrence in'theeventsequences.
Comparing bothfrequency andrequirements datatotheinventory, identification ismadeof:1)therabsence(intheControlRoom)oftaskrequiredinformation orcontrol,2)theestimated frequency with,whichtheinformation orcontrolisrequired, and3)theconditions (events,procedures, etc.)underwhichtheinformation orcontrolisrequired.
Basedontheabove,HEDsareidentified anddocumented.
Thesecondsubtask,verification ofsuitability, involvesusingspatial-operational sequencediagrams, trafficpatterndiagrams, identified functional groups,andchecklists toevaluatehumanengineering suitability intermsofsequenceofcomponent use,control/display proximity,etc.
TheNUREGW?00 guidelines serveasthesourcedocumentforevaluation criteria.
1.2.2.6ValidateControlRoomFunctions
-Thisinvolvesanalysisofworkloadanddistribution ofworkloadforoperators forspecifictaskandeventsequences, andoverallControlRoomtraffic.Themeansoftheanalysisare:1)tasktimelines, 2)trafficanalysis, and3)walk-andtalk-through simulation oftasksequences.
Checklists willbeusedtoaidinthevalidation ofControlRoomfunctions.
