-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.

1.2.2.7AssessDiscrepancies

-Assessment isdiscussed inSection5.0ofthisplan.Ingeneral,theprocess'is similartothatdiscussed inNUREG-0801 (draft,published inOctober,1981),andisasfollows:2.3.4,5..Assessextentofdeviation fromNUREG-0700 guidelines Estimateincreaseinhumanerrorforthediscrepancy Determine ifdiscrepant component(s) performsafetyfunctions Determine iferrorsinusingdiscrepant component(s) couldleadtoviohtionoftechspecsorleadtounsafeoperation Assignment ofcategoryandpriority, basedontheabove.1.2.3Phase3-Enhancement andDesignSolutions Thelogicpathtobeemployedinidentifying andselecting enhancements anddesignsolutions isbasedonNUREG-0700, Exhibit4-2,asshowninPigure2.1.Analysisofcorrection byenhancement 2.Analysisofcorrection bydesignalternatives 3.Assessextentofcorrection.
