(DENC) submitted a letter requesting approval inalternative requests RR-04-27 for IR-3-38 for Millstone Power Station Unit 2 (MPS2) andMillstone Power Station Unit 3 (MPS3), respectively, to use encoded phased arrayultrasonic examination techniques as an alternative to radiographic examination. The purpose of this e-mail is to provide the results of the Nuclear Regulatory Commission(NRC) staff's acceptance review of this licensing request. The acceptance review wasperformed to determine if there is sufficient technical information in scope and depth toallow the NRC staff to complete its detailed technical review. The acceptance review isalso intended to identify whether the application has any readily apparent informationinsufficiencies in its characterization of the regulatory requirements or the licensing basis ofthe plant. The NRC staff has reviewed DENC's application and concludes that it does providetechnical information in sufficient detail to enable the NRC staff to complete its detailedtechnical review and make an independent assessment regarding the acceptability of theproposed amendment in terms of regulatory requirements and the protection of publichealth and safety and the environment. Given the lesser scope and depth of theacceptance review as compared to the detailed technical review, there may be instances inwhich issues that impact the NRC staff's ability to complete the detailed technical revieware identified despite completion of an adequate acceptance review. You will be advised ofany further information needed to support the NRC staff's detailed technical review byseparate correspondence. Based on the information provided in your submittal, the NRC staff has estimated that thereview of the relief requests will take approximately 110 hours0.00127 days <br />0.0306 hours <br />1.818783e-4 weeks <br />4.1855e-5 months <br /> to complete. The NRC staffexpects to complete this review by September 2018 (i.e., approximately 7 months). If thereare emergent complexities or challenges in our review that would cause changes to theinitial forecasted completion date (greater than a month) or significant changes in theforecasted hours (greater than 25%), the reasons for the changes, along with the newestimates, will be communicated during the routine interactions with the assigned projectmanager. These estimates are based on the NRC staff's initial review of the applicationand they could change, due to several factors including requests for additional information,and unanticipated addition of scope to the review. Additional delay may occur if thesubmittal is provided to the NRC in advance or in parallel with industry program initiativesor pilot applications. Please contact me if you have any questions. A copy of this email will be made publiclyavailable in ADAMS. Thanks,
