SUBJECT: DRESDEN NUCLEAR PLANT, UNIT 3 - NOTIFICATION OF NRC

BASELINE INSPECTION AND REQUEST FOR INFORMATION;

INSPECTION REPORT 05000249/2016004

Dear Mr. Hanson:

On October 31, 2016, the U.S. Nuclear Regulatory Commission (NRC) will begin the Baseline

Inservice Inspection Procedure 71111.08. This onsite inspection is scheduled to be performed

October 31, 2016, through November 4, 2016.

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 onsite 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

onsite 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. DJ Walker, of your organization. If there are

any questions about this inspection or the material requested, please contact the lead inspector

Dr. Laura Smith at 630-829-9688, or via e-mail at Laura.Smith@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.

Public Document Room or from the Publicly Available Records (PARS) component of the NRC's

I. Information for the In-Office Preparation Week

The following information (electronic copy CD ROM if possible) is requested by

October 17, 2016, to facilitate the selection of specific items that will be reviewed during

the onsite inspection week. The inspector will select specific items from the information

requested below and request a list of additional documents needed onsite to your staff.

We request that the specific items selected from the lists be available and ready for

review on the first day of inspection. 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 (NDEs) planned for Class 1 and 2 Systems

and containment, performed as part of your American Society of Mechanical

Engineers (ASME) Code Inservice Inspection (ISI) Program (include edition

and addenda of Code committed to), and NDEs planned for other systems

performed as part of a Risk-Informed 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.

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 examination.

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. Copy of any Title 10 Code of Federal Regulations, Part 21 reports applicable to your

structures, systems, or components within the scope of Section XI of the ASME

Code that have been identified since the beginning of the last refueling outage.

II. Onsite Information to be Provided to the Inspector on the First Day of the

Inspection (e.g., Following the Entrance Meeting). Please Provide Hard Copies

(e.g., Paper Records) of the Following Documents.
