Each year following submittal of alicense renewal application (LRA) and at least 3 months before scheduled completion ofthe NRC review, 10 CFR 54.21(b) requires an amendment to the renewal application tobe submitted identifying any change to the current licensing basis (CLB) of the facilitythat materially affects the contents of the license renewal application, including the FinalSafety Analysis Report (FSAR) supplement.The Attachment provides a summary of the CLB changes that materially affect the LRA.Enclosure A provides Amendment No. 30 (Annual Update) to the DBNPS LRA as requiredby 10 CFR 54.21(b). Enclosure B provides new and revised LRA boundary drawings.There are no regulatory commitments contained in this letter.

L-12-262Current Licensing Basis (CLB) Changes that Materially Affect theDavis-Besse Nuclear Power Station, Unit No. 1 (Davis-Besse),License Renewal Application (LRA),Page 1 of 1A review of Davis-Besse CLB document changes since submittal of the 2011License Renewal Application Annual Update provided by FENOC letter datedSeptember 30, 2011 (ML1 1276A078), identified two design changes that materiallyaffect the contents of the Davis-Besse License Renewal Application, as follows:1 .The Chemical Addition System was modified in March of 2012 to install a zincinjection skid. The components of the zinc injection skid satisfy the scoping criteriaof 10 CFR 54.4(a)(2), and are highlighted on new license renewal boundarydrawing LR-M045, Sheet 1. The aging management review results for the zincinjection skid are included in LRA Table 3.3.2-5, "Aging Management ReviewResults -Chemical Addition System."LRA Section 2.3.3.5, "Chemical Addition System," Table 2.3.3-5, "ChemicalAddition System Components Subject to Aging Management Review," Section3.3.2.1.5, "Chemical Addition System," and Table 3.3.2-5, "Aging ManagementReview Results -Chemical Addition System," are revised to account for theaddition of the zinc injection skid. New license renewal boundary drawingLR-M045, Sheet 1 is added to depict the evaluation boundary of the zinc injectionskid. Plant modifications associated with the addition of the zinc injection skid alsoresulted in changes to license renewal boundary drawings LR-MO10D Sheet 1,LR-M031A, LR-M037D and LR-M045.2. An articulating boom crane, known as the Containment Auxiliary Crane, wasinstalled as permanent plant equipment during the Cycle 17 refueling outage thatended on June 13, 2012. This crane is capable of handling heavy loads, andtherefore is subject to the requirements set forth in NUREG-0612, "Control ofLifting and Handling of Heavy Loads." The license renewal "Cranes and HoistsInspection Program" is credited with managing the aging effects applicable to thecrane structural components.LRA Sections A. 1.10 and B.2.10, both titled "Cranes and Hoists InspectionProgram," and Section A. 1.44, "References," are revised to include reference toAmerican National Standards Institute (ANSI) B30.22, "Articulating Boom Cranes."See Enclosure A to this letter for the revision to the Davis-Besse LRA.See Enclosure B to this letter for the new and revised LRA Boundary Drawings.

Additionally, a new license renewalboundary drawing number is added to the list of "License Renewal Drawings,"and the bulleted item under the 3rd paragraph of "Components Subject to AMR,"is revised. LRA Section 2.3.3.5 is revised to read as follows:2nd Paragraph revision:The Chemical Addition System provides a boric acid solution to the Boric AcidAddition System, and provides lithium hydroxide, hydrazine, ammonia, and otherchemical amines to control pH and oxygen in the plant systems fed by theReactor Coolant Chemical Addition System and Steam Generator Wet LayupChemical Addition System. In addition, the Chemical Addition System injects zincacetate into the RCS to reduce the radiation source term and for mitigation ofprimary water stress corrosion cracking (PWSCC) of Alloy 600 components.New 5th Paragraph:Zinc acetate is mixed into the Zinc Iniection Mix Tank (DB-T99) with a mixer.Demineralized water is supplied from the Demineralized Water System. Thesolution is transferred from the Zinc Injection Mix Tank by one of two ZincInjection Pumps (DB-P295-1 and DB-P295-2) that are capable of independentoperation. The Chemical Addition System injects zinc acetate into the RCS toreduce the radiation source term and for mitigation of primary water stresscorrosion crackina (PWSCC) of Alloy 600 components
