Terry Herrmann SIA REQUESTS FOR ADDITIONAL INFORMATION VERMONT YANKEE NUCLEAR POWER STATION LICENSE RENEWAL APPLICATION DECEMBER 18, 2007 The U.S. Nuclear Regulatory Commission (NRC or the staff) and representatives of Entergy Nuclear Operations, Inc. held a telephone conference call on December 18, 2007, to discuss and clarify the following request for additional information (RAI) concerning the Vermont Yankee Nuclear Power Station (VYNPS) license renewal application.
RAI 4.3.3-2 Your response to audit question # 387 in your November 14, 2007, letter states that "In most cases the maximum component stress difference with time matched the maximum stress intensity calculated by ANSYS. This shows that shearing stresses are negligible for the thermal transient at that location and the maximum component stress difference is the maximum stress intensity."
Please identify the exceptions where maximum component stress difference with time did not match the maximum stress intensity calculated by ANSYS. In addition, please justify the exceptions, based on quantitative evaluations, that the shearing stresses are negligible and the maximum component stress difference is the maximum stress intensity for the branch nozzle blend radius (nozzle corner) locations with geometrical discontinuities for the applicable thermal transients. Your response should cover the shearing stress differences at the 0-180 degree axis and the 90-270 degree axis to the pipe run axis.
Discussion: The response to RAI 4.3.3-2, submitted by VY on December 11, 2007, was reviewed by several staff and discussed during the conference call. The staff indicated that the response did not adequately demonstrate that the shearing stresses are negligible and that the response also raised uncertainty of the validity of the methodology used to calculate stresses.
The NRC and Entergy staffs discussed alternative approaches for addressing environmentally assisted fatigue (EAF) for all NUREG/CR-6260 nozzle locations at VY and the use of the industry accepted computer code ANSYS.
Entergy indicated that some terminology misunderstanding may exist between the two sides.
Entergy requested a face-to-face meeting to ensure the understanding pertaining to this highly technical issue was properly and effectively communicated.
