RAIs 3.1.1-60-1, 3.1.1-60-2, and RAI 4.3.3-2 dated January 5, 2011, and follow-up RAI 3.1.1-60-01/02 dated March 30, 2011.
In response to RAI 3.1.1-60-2, by letter dated February 3, 2011, on page 9 of 92, the applicant stated, The flux thimble tube no longer provides a function of pressure boundary hence, it has no license renewal function, and it will be removed from scope.
In response to follow-up RAI 3.1.1-60-01/02, by letter dated April 22, 2011, on page 6 of 43, the applicant stated, When the incore detector assembly is inserted, the thimble housing tube (outer tube) provides the RCS pressure boundary to keep the incore detector assembly internal volume dry. The letter further stated that, The thimble calibration tube (inner tube), although considered a RCS pressure boundary, is not in contact with reactor coolant.
Following the August 3rd, 2001 teleconference discussion on the above topic, the staff still seeks clarification as to where exactly the applicant is taking credit for the RCS pressure boundary for the incore detector assemblies in the applicants LRA and how it is dispositioned under 10 CFR 54.
