SUBJECT:

Davis-Besse Nuclear Power Station, Unit No. 1 Docket No. 50-346, License Number NPF-3 License Renewal Application Amendment No. 30 -Annual Update (TAC No. ME4640)By letter dated August 27, 2010 (Agencywide Documents Access and Management System (ADAMS) Accession No. ML102450565), FirstEnergy Nuclear Operating Company (FENOC) submitted an application pursuant to Title 10 of the Code of Federal Regulations, Part 54 for renewal of Operating License NPF-3 for the Davis-Besse Nuclear Power Station, Unit No. 1 (Davis-Besse).

Each year following submittal of a license renewal application (LRA) and at least 3 months before scheduled completion of the NRC review, 10 CFR 54.21(b) requires an amendment to the renewal application to be submitted identifying any change to the current licensing basis (CLB) of the facility that materially affects the contents of the license renewal application, including the Final Safety 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 required by 10 CFR 54.21(b).

Enclosure B provides new and revised LRA boundary drawings.There are no regulatory commitments contained in this letter. If there are any questions or if additional information is required, please contact Mr. Clifford I. Custer, Fleet License Renewal Project Manager, at 724-682-7139.

I declare under penalty of perjury that the foregoing is true and correct. Executed on August __, 2012.Sincerely, Barry S. Allený' / ()5 K19 X F--F-Davis-Besse Nuclear Power Station, Unit No. 1 L-12-262 Page 2

The components of the zinc injection skid satisfy the scoping criteria of 10 CFR 54.4(a)(2), and are highlighted on new license renewal boundary drawing LR-M045, Sheet 1. The aging management review results for the zinc injection skid are included in LRA Table 3.3.2-5, "Aging Management Review Results -Chemical Addition System." LRA Section 2.3.3.5, "Chemical Addition System," Table 2.3.3-5, "Chemical Addition System Components Subject to Aging Management Review," Section 3.3.2.1.5, "Chemical Addition System," and Table 3.3.2-5, "Aging Management Review Results -Chemical Addition System," are revised to account for the addition of the zinc injection skid. New license renewal boundary drawing LR-M045, Sheet 1 is added to depict the evaluation boundary of the zinc injection skid. Plant modifications associated with the addition of the zinc injection skid also resulted 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, was installed as permanent plant equipment during the Cycle 17 refueling outage that ended on June 13, 2012. This crane is capable of handling heavy loads, and therefore is subject to the requirements set forth in NUREG-0612, "Control of Lifting and Handling of Heavy Loads." The license renewal "Cranes and Hoists Inspection Program" is credited with managing the aging effects applicable to the crane structural components.

LRA Sections A. 1.10 and B.2.10, both titled "Cranes and Hoists Inspection Program," and Section A. 1.44, "References," are revised to include reference to American 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.

Letter L-1 2-262 Amendment No. 30 (Annual Update) to the Davis-Besse License Renewal Application Page 1 of 10 License Renewal Application Sections Affected Section 2.3.3.5 Table 2.3.3-5 Section 3.3.2.1.5 Table 3.3.2-5 Section A. 1.10 Section A. 1.44 Section B.2.10 The Enclosure identifies the change to the License Renewal Application (LRA) by Affected LRA Section, LRA Page No., and Affected Paragraph and Sentence.

The count for the affected paragraph, sentence, bullet, etc. starts at the beginning of the affected Section or at the top of the affected page, as appropriate.

Below each section the reason for the change is identified, and the sentence affected is printed in italics with deleted text fined-e and added text underlined.

Enclosure A L-12-262 Page 2 of 10 Affected LRA Section LRA Page No. Affected Paragraph and Sentence 2.3.3.5 Pages 2.3-62 Description, 2 nd paragraph and new and 2.3-63 5 th paragraph; License Renewal Drawings, new drawing; and, Components Subject to AMR, 3 rd paragraph, bulleted item Based on the installation of the new Zinc Injection System, the 2 nd paragraph is revised and a new 5 th paragraph is added to the "Description" of LRA Section 2.3.3.5, "Chemical Addition System." Additionally, a new license renewal boundary drawing number is added to the list of "License Renewal Drawings," and the bulleted item under the 3 rd paragraph of "Components Subject to AMR," is revised. LRA Section 2.3.3.5 is revised to read as follows: 2 nd Paragraph revision: The Chemical Addition System provides a boric acid solution to the Boric Acid Addition System, and provides lithium hydroxide, hydrazine, ammonia, and other chemical amines to control pH and oxygen in the plant systems fed by the Reactor Coolant Chemical Addition System and Steam Generator Wet Layup Chemical Addition System. In addition, the Chemical Addition System injects zinc acetate into the RCS to reduce the radiation source term and for mitigation of primary water stress corrosion cracking (PWSCC) of Alloy 600 components.

New 5 th 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. The solution is transferred from the Zinc Injection Mix Tank by one of two Zinc Injection Pumps (DB-P295-1 and DB-P295-2) that are capable of independent operation.

The Chemical Addition System injects zinc acetate into the RCS to reduce the radiation source term and for mitigation of primary water stress corrosion crackina (PWSCC) of Alloy 600 components Enclosure A L-12-262 Page 3 of 10 License Renewal Drawings The following license renewal drawings depict the evaluation boundaries for the system components within the scope of license renewal: LR-M035, LR-M037D, LR-M039A, LR-M039B, LR-M045, LR-M045 Sheet I Components Subject to AMR In addition to those components specifically excluded in 10 CFR 54.21(a)(1)(i), such as instruments, the following components are within the scope of license renewal but are not subject to AMR: The internals (screens) for the lithium hydroxide mix tank discharge strainer (DB-S334), the and-hydrazine pump suction strainer (DB-S335).

the zinc iniection pumps suction strainer (DB-S463) and the zinc injection pumps discharge strainer (DB-S464) are not subject to AMR because these strainers are in scope only for potential leakage and spray considerations in accordance with 10 CFR 54.4(a) (2), and serve only a structural integrity function.
