Theproposedamendment isalineitemimprovement basedontherecommendations ofgenericletter(GL)90-02supplement 1,"Alternative Requirements forFuelAssemblies intheDesignFeaturesSectionofTechnical Specifications."

Theproposedchangeswillpermitremovalofsuspected defective fuelrods,allowingforfuturereductions inoccupational radiation

exposure, andplantradiological releases.

ATTACHMENT 1TOAEP:NRC:1124B Page1I.DESCRIPTION OFCHANGESWeareproposing tomodifytechnical specification (T/S)5.3.1(DesignFeatures-FuelAssemblies) toallowforfuelreconstitution.

Themodifiedstatement permits"limitedsubstitutions ofzirconium alloyorstainless steelfillerrods,inaccordance withNRC-approved applications offuelrodconfigurations."

II.JUSTIFICATION FORCHANGESTheproposedT/Samendment isalineitemimprovement basedontheguidanceofgenericletter(GL)90-02supplement 1,"Alternative Requirements forFuelAssemblies intheDesignFeaturesSectionofTechnical Specifications."

ThepresentT/Srequirement forfuelassemblies specifies thequantityoffuelassemblies andthenumberoffuelrodsperassembly.

Flexibility todeviatefromthenumberoffuelrodsperassemblyisdesirable topermitremovaloffuelrodsthatarefoundto'beleakingoraredetermined tobeprobablesourcesoffutureleakage,sothatreuseofthemajorityoftheaffectedfuelassemblyispermitted withminimalimpactoncoredesign.forthesubsequent fuelcycle.Thisimprovement mayprovidereductions infutureoccupational radiation exposureandplantradiological releases.

Theproposedchangetoallowreconstitution isconsistent withtherecommendation ofGL90-02supplement 1.Substitution islimitedtozirconium alloyorstainless steelfillerrods(i.e.,noopenwaterchannelsarepermitted).

Also,substitution mustbeinaccordance with"NRC-approved applications offuelrodconfigurations."

Genericletter90-02supplement 1states:"Thestaffconsiders anNRC-approved methodology tobeanymethodology thattheNRCstaffhasexplicitly approvedinawrittensafetyevaluation oraplant-specifictechnical basis.ThatNRC-approvedmethodology mustbeusedonlyforthepurposeandthescopeofapplication specified intherevieweddocumentasapprovedormodifiedintheNRCapprovaldocumentation."
