Although, claddingtubeswerepart oftheoriginalNRC approved cask configurationintheold8-120B secondarylids(usedbefore August 31,2013),theywere inadvertentlyomittedinthenew secondarylidsdesignenteredinto service in September,2013.Duetothis condition, EnergySolutions suspendedtheuse ofthe8-120B casks with subject secondarylids.Further, EnergySolutions, on September16,2015, submittedaCoC amendment requesttoNRC requesting authorized usage of the subject secondary lids.EnergySolutionswillretrofitall 120B secondarylidswiththetubedesignatthe earliest opportunity.

We expectthattheNRCwillgrantanewCoC (Rev.22)shortlyandtheuse of the affected 8-120B caskswithsubject secondarylidswillresume.Allour8-120Buserswillbe providedwitha separate notificationandanupdated 8-120Bcaskbookwhichwi IIclarifythestatus of the affectedCoCthatthe120Bcaskscan operate under.Pleasesee EnergySolutions' attached report containing the informationrequiredby10CFR71.95.Inthereport, EnergySolutions describesthecause of the occurrenceandprovides information that supportsthatthere isnosafety significance associatedwiththis condition.

The purpose of the secondarylidtestporttubeistoisolatethe pre-shipment test volume from the interspace betweenthetwo31/4" thick platesthatmakeupthe secondarylid.The isolation ofthetest volume providedbythetube assuresthatthetest volumedoesnotexceedthelimitonwhichtheholdtimeforthe pre-shipmentleakratetestisbased.

However,ifthefreevolumeinthe interspace between the plates is negligible,thentheisolationfunction ofthetubeisnot necessary.Thetubewasshownasadesignfeatureinthe8-120BSAR drawings referenced by Revision 17 oftheCoC,and previous revisions,butthetubewasnot creditedwithanysafetyfunctionintheSAR.Thetubewas inadvertently omittedwhenthelidswere redesigned for operational enhancementsinCoC Revision19.The omission was identified by EnergySolutions' correctiveactionsystemwhilethe subjectlidswerestillinfabrication.A correctiveactionwas assigned to measure the as-built test volumes,whichincludedthevoid space betweenthethick platessincetherewerenotubesinstalled.Thetest volumes werefoundto exceedthevolumebasisfor pre-shipmentleakratetestholdtime calculatedintheSAR.Thetubeswere thereforeinstalled,andthelidswere placed on QA-hold using EnergySolutions' noncompliance procedure becausetheydidnotmeetthelid configuration authorizedbytheCoCin effectatthattime(Le.,CoC,Rev.20).

EnergySolutions subsequentlymadea determinationthatprior NRC authorizationwasnot required (becausethetubeshadbeenpart of the previous NRC-approved 8-120B caskdesignandwere inadvertently omittedfromthenew secondary lid design), clearedthehold,andreleasedthelidsforuse.Thetubeswere restoredtotheSAR drawingsaspart of a broader license amendment request submittedinMay2014,butthe request was withdrawn for unrelatedreasons.Anewlicense amendment request submittedtotheNRCon 9/16/2015 reintroducesthetubestothe secondaryliddesign.
