VERMONT YANKEE NUCLEAR POWER STATION DOCKET NO. 50-271
On January 4, 20051, the NRC provided to VY a Draft Request for Additional Information regarding Technical Specification Proposed Change No. 268. The Following provides the response to request for additional information.
Question 1:
The licensee's discussion of the Inservice Inspection (ISI) Program on page 5 of Attachment I of the application indicates that, based on the 1998 Edition of ASME Section XI through the 2000 Addenda, VYNPS performs Category E-A examinations (General Visual Examinations) in accordance with Table IWE-2500-1. These general visual examinations cover the interior and exterior pressure retaining boundary (Item E1.10), accessible surface areas (Item El 1), and moisture barriers (Item El.30). Provide a detailed description of the acceptance criteria used for visual examination of containment surfaces and how these general visual examinations are performed.
Response to Question 1:
The visual examinations of the interior and external containment surfaces utilize an Entergy Nuclear Northeast common standard, ENN-EP-S-001 "IWE General Visual Containment Inspection." In general, the standard contains criteria derived from various ASTM documents for determining the condition of coated and uncoated surfaces (e.g., extent of corrosion, blistering, flaking, cracking, etc.). For a detailed description of the acceptance criteria used for these visual exams, please reference ENN-EP-S-001 "IWE General Visual Containment Inspection," provided as Attachment 2 to this letter. In addition, for details regarding the inspection schedule of the containment structure, please reference Table I from PP 7024 "Containment Inservice Inspection Program (IWE)" which is being provided as Attachment 3 to this letter.
Question 2:
For the examination of penetration seals and gaskets, and examination and testing of bolted connections associated with the primary containment pressure boundary (Examination Categories E-D and E-G), relief for the requirements of the Code had been requested by some nuclear plant licensees. As an alternative, these licensees proposed to examine the containment components during the leak-rate testing of the primary containment. Since the application states that there are no Relief Requests in effect for the containment ISI program, the staff requests the licensee to provide a detailed description of how the above items are examined, including the schedule for examinations.
Response to Question 2:
The Code of Record does not contain Categories E-D or E-G. However, containment bolted connections, Table IWE-2500-1, Category E-A, Item El.11, are examined in accordance with the requirements of I OCFR50.55a(b)(2)(ix)(H):
"Containment bolted connections that are disassembled* during the scheduled performance of the examinations in Item EL.I 1 of Table IWE-2500-1 must be examined using the VT-3 examination method. Flaws or degradation identified during the performance of a VT-3 examination must be examined in accordance with the VT-I examination method. The criteria in the material specification or IWB-3517.1 must be Reference Memorandum from D. Roberts (USNRC) to R. Ennis (USNRC), NVY 05-46, "Vermont Yankee Nuclear Power Station - Draft Request for Additional Information (TAC No. MC4662)," dated March 28, 2005.
BVY 0540, Attachment 1,Page I of 2
used to evaluate containment bolting flaws or degradation. As an alternative to performing VT-3 examinations of containment bolted connections that are disassembled during the scheduled performance of Item El.11, VT-3 examinations of containment bolted connections may be conducted whenever containment bolted connections are disassembled for any reason."
The enclosed Table 1 of PP 7024 contains the scheduled VT-3 examinations of bolting (Attachment 3).
Question 3:
NRC Information Notice 92-20, "Inadequate Local Leak Rate Testing," was issued to alert licensees of problems with local leak rate testing of two-ply stainless steel bellows used on piping penetrations at some plants. Specifically, local leak rate testing could not be relied upon to accurately measure the leakage rate that would occur under accident conditions since, during testing, the two plies in the bellows were in contact with each other, restricting the flow of the test medium to the crack locations.
Any two-ply bellows of similar construction may be susceptible to this problem. Please discuss the applicability of this issue to VYNPS, and if applicable, provide information regarding inspection and testing of the bellows, and how such behavior has been factored into the risk assessment submitted in support of this license amendment request.
Response to Question 3:
Vermont Yankee expansion bellows are a single ply design. The conditions identified in IN 92-20 are not applicable to Vermont Yankee due to our configuration. As such, the Type B tests are capable of detecting through wall defects. The bellows are tested in accordance with the VY Primary Containment Leakage Rate Testing Program implementing Option B of IOCFR50 Appendix J at a frequency of 10 years on a staggered basis. It is noted that even though Vermont Yankee's configuration is of a different design, the potential for undetected through wall defects was factored into the risk assessment.

Non-integral attachments include such items as insulation supports, nameplates, locating and lifting lugs, lighting supports, shear plates or rings, retainer rings, and walkway supports.
3.21 Pitting - Localized corrosion that generally produces sharply defined open or closed cavities in a metal surface.
3.22 Relevant Condition - A condition observed during a visual examination that requires supplemental examination, corrective measure, and correction by repair/replacement, or analytical evaluation.
3.23 Responsible Individual - Individual responsible for Implementation of the containment IWE inspection program as described in the program plan, references 2.14, 2.15,2.21, 2.22, and 2.23.
3.24 Rusting - The presence of oxidation In the form of iron oxide on steel.
3.25 Structural Integrity - The ability of a structure of component to withstand prescribed design loads.
3.26 Undercutting (coating) - Appears as a raised coated rust bloom. Undercutting is actually rust forming under the coating and acting as a wedge to push the coating off the metal surface. The undercutting may crack the coating surface.
3.27 Wear - A gradual removal of a substance caused by friction. In paint or coating the wear may appear as a different color or thickness. In base metal the wear areas may appear brighter in appearance or as a low area.
