SUBJECT:
EDWIN I. HATCH NUCLEAR PLANT UNIT 2 - NOTIFICATION OF INSPECTION AND REQUEST FOR INFORMATION
Dear Mr. Vineyard:
From February 13 - 17, 2017, the U.S. Nuclear Regulatory Commission (NRC) will perform the baseline in-service inspection (ISI) at the Edwin I. Hatch Nuclear Plant, Unit 2, in accordance with NRC inspection procedure (IP) 71111.08, Inservice Inspection Activities. Experience has shown that this inspection is resource-intensive for both the NRC inspectors and your staff. In order to minimize the impact to your onsite resources and to ensure a productive inspection, we have enclosed a request for information. Section A of the Enclosure identifies information to be provided prior to the inspection, to ensure adequate sample selection and preparation. Section B of the Enclosure identifies additional information the inspectors will need upon arrival at the site, to complete the review of inspection samples. The inspection staff will appreciate if all the documents requested 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 this inspection activity with your staff, and understand that our regulatory contact for this inspection will be Jimmy Collins of your organization. Our inspection dates are subject to change based on your updated schedule of outage activities. If there are any questions about this inspection or the material requested, please contact the inspector, Robert Carrion at 404-997-4522, or robert.carrion@nrc.gov.
In accordance with Title 10 of the Code of Federal Regulations 2.390, Public inspections, exemptions, requests for withholding, of the NRC's "Rules of Practice," a copy of this letter, and its Enclosure, will be available electronically for public inspection in the NRC Public Document Room, or from the Publicly Available Records (PARS) component of NRCs Agencywide
D. Vineyard 2 Documents Access and Management System (ADAMS); accessible from the NRC Web site at http://www.nrc.gov/reading-rm/adams.html (the Public Electronic Reading Room).

A.1 Non-destructive Examination and Welding Activities
- a. A detailed schedule (including preliminary dates) of nondestructive examinations (NDEs) planned for the structures, systems, and components (SSCs) listed below as part of the Inservice Inspection (ISI) Program required by the American Society of Mechanical Engineers (ASME) Boiler and Pressure Vessel Code (BPVC),Section XI, as incorporated by reference in 10 CFR 50.55a, and other augmented ISI activities:
- ASME Class 1, 2, and 3 components and supports (including Risk-Informed ISI Program)
2
- ASME Class MC supports
- Reactor coolant system components as part of the Electric Power Research Institute (EPRI) Boiling Water Reactors Vessel and Internals Project (BWRVIP)
- other components to be inspected through NDE in accordance with industry initiatives or requirements (e.g., Flow Accelerated Corrosion Program)
- b. A detailed schedule (including preliminary dates) of welding activities to be completed on ASME Code Class 1, 2, or 3 components, and supports during the upcoming refueling outage.
- c. A list of NDE reports (ultrasonic, radiographic, magnetic particle, and liquid penetrant) addressing surface or volumetric indications that were analytically evaluated, and accepted for continued service in ASME Code Class 1, 2, and 3 components, since the beginning of the last refueling outage. This should also include any evaluations for continuous service performed as a result of Section XI pressure tests conducted during startup from the last refueling outage.
- d. A list of the welds in ASME Code Class 1, 2, and 3 systems that have been fabricated due to component repair/replacement activities since the beginning of the last refueling outage. Please include a brief description of the welds such as system, material, pipe size, weld number, and NDEs performed. In addition, please indicate which of those welds are risk-significant.
- e. If NDE of pressure retaining welds in the reactor vessel shell required by the ASME BPVC,Section XI, Subsection IWB (also known as 10-year Reactor Vessel ISI) are scheduled to occur during the upcoming outage, provide a detailed description of the welds to be examined, and the extent of the planned examination. Please include reference numbers for applicable procedures that will be used to conduct these examinations.
- f. A copy of ASME BPVC,Section XI Relief Requests and associated NRC Safety Evaluation Reports applicable to the NDEs scheduled for the upcoming refueling outage.
