SUBJECT:

DRESDEN NUCLEAR PLANT, UNIT 2 - NOTIFICATION OF NRC INSPECTION AND REQUEST FOR INFORMATION - BASELINE INSPECTION Dear Mr. Hanson

On November 2, 201 5 , the U.S. Nuclear Regulatory Commission (NRC) will begin the baseline Inservice Inspection Procedure 71111.08. This on-site inspection is scheduled to be performed November 2

- 6, 2015. Experience has shown that this inspection is resource intensive both for the NRC inspector and your staff. In order to minimize the impact to your on

-site resources, and to ensure a productive inspection for both sides, we have enclosed a request for documents needed for this inspection. These documents have been divided into two groups.

The first group identifies information necessary to ensure that the inspector is adequately prepared. The second group identifies the information the inspector will need upon arrival at the site. It is important that all of these documents are up

-to-date, and complete, in order to minimize the number of additional documents requested during the preparation and/or the on-site portions of the inspection.

We have discussed the schedule for inspection activities with your staff and understand that our regulatory contact for this inspection will be Mr.

D. Walker, of your organization. If there are any questions about this inspection or the material requested, please contact the lead inspector Mr. T. Bilik at 630

-829-9744, or via e

-mail at Tom.Bilik@nrc.gov

. This letter does not contain new or amended information collection requirements subject to the Paperwork Reduction Act of 1995 (44 U.S.C. 3501 et seq.). Existing information collection requirements were approved by the Office of Management and Budget, Control Number 3150-0011. The NRC may not conduct or sponsor, and a person is not required to respond to, a request for information or an information collection requirement unless the requesting document displays a currently valid Office of Management and Budget Control Number.

In accordance with Title 10 of the Code of Federal Regulations (10 CFR) 2.390 , "Public Inspections, Exemptions, Requests for Withholding,"

of the NRC's "Rules of Practice," a copy of this letter, its enclosure, and your response (if any) will be available electronically for public inspection in the NRC

's Public Document Room or from the Publicly Available Records (PARS) component of the NRC's Agencywide Document s Access and Management System (ADAMS).

If you have any questions regarding this information, please call the inspector as soon as possible.

1. For the upcoming outage, a detailed schedule and description of:

a. Non-Destructive Examinations (NDE s) planned for Class 1 and 2 Systems and containment, performed as part of your American Society of Mechanical Engineers (ASME) Code Inservice Inspection (IS I) Program (include edition and addenda of Code committed to), and NDE examinations planned for other systems performed as part of a Risk

-Informed (RI)

-ISI Program, or other augmented inspection programs commitments

, as part of an industry initiative. For each weld examination, include the weld identification number, description of weld (component name), category, class, type of exam and procedure number, and date of examination; and

b. Welding on Code Class 1, 2, or 3 components.

2. A copy of the NDE procedures and welding procedures used to perform the activities identified in A.1 (including NDE calibration and flaw characterization/

sizing procedures and Welding Procedure Qualification Records). For ultrasonic examination procedures qualified in accordance with Appendix VIII, of Section XI , of the ASME Code, provide documentation supporting the procedure qualification (e.g., the Electric Power Research Institute performance demonstration qualification summary sheets).

3. A copy of ASME Section XI, Code Relief Requests applicable to the examinations identified in A

.1.A copy of the 10

-year ISI Program showing those required exams scheduled to be performed this outage, and those which have been completed.

2 4. A list identifying NDE reports (ultrasonic, radiography, magnetic particle, or dye penetrant), which have identified relevant indications on Code Class 1 and 2 Systems since the beginning of the last refueling outage.

5. List with short description of the welds in Code Class 1 and 2 Systems, which have been fabricated due to component repair/replacement activities since the beginning of the last refueling outage and identify the system, weld number, and reference applicable documentation (e.g., NIS

-2 forms with definitions of system and component acronyms).

6. If reactor vessel weld examinations required by the ASME Code are scheduled to occur during the inspection period, provide a detailed description of the welds to be examined, and the extent of the planned examinatio

n. 7. List with description of ISI

-related issues such as piping degradation or damage (e.g., cracks, wall thinning, wear, microbiologically induced corrosion) or errors identified in piping examinations that have been entered into your corrective action system since the beginning of the last refueling outage. Also, include a list of corrective action records associated with foreign material introduced/identified in the reactor vessel or reactor coolant system since the beginning of the last refueling outage. 8.
