ENCLOSURE 2 ADDITIONAL INFORMATION DATED AUGUST 14, 2008 INDIAN POINT NUCLEAR GENERATING UNIT NOS. 2 AND 3 LICENSE RENEWAL APPLICATION OPERATING EXPERIENCE August 27, 2008 The U.S. Nuclear Regulatory Commission (NRC or the staff) and representatives of Entergy Nuclear Operations, Inc. (Entergy or the applicant) held a telephone conference call on August 27, 2008, to obtain clarification of the following additional information submitted by the applicant by letter dated August 14, 2008 concerning the Indian Point Nuclear Generating Unit Nos. 2 and 3 (IP2 and IP3) license renewal application.
Audit Question 27 Response The staff asked the applicant to describe the containment liner insulation and to clarify why the liner behind the insulation is being treated as inaccessible. The staff asked the applicant whether the insulation panels are sealed. The applicant stated that the insulation is encapsulated in a stainless steel jacket and contains a layer of asbestos. The staff asked if the insulation could be removed. The applicant stated that removal of the insulation is an asbestos abatement issue. The applicant stated that, in order to prevent moisture intrusion, the insulation jacket panels are sealed at the joints, at the top where it interfaces with un-insulated liner, and at the bottom where it interfaces with the concrete floor slab. Approximately 20-percent of the liner is insulated. Hence, the liner behind the insulation is treated as inaccessible.
Audit Question 358 Response The staff did not require any clarification on this response.
Audit Question 359 Response The staff asked the applicant to describe where the reactor refueling cavity leakage was occurring and what type of coatings were in place in the refueling cavity. The applicant stated that the leakage occurs only during refueling and is occurring from the degraded stainless steel liner, and that it is not occurring in the area of the seals. The applicant indicated that the observed leakage is 5 to 10 gallons per minute. With regard to the coating, the applicant stated that the welds are coated with ceramalloy which is proving to be too rigid. The ceramalloy is being replaced with insta-coat, but the replacement is happening piecemeal. The insta-coat has slowed the leakage. The applicant stated that it is in the process of developing an action plan which will be tracked in the corrective action program but is subject to change. The applicant agreed to provide a summary of the planned corrective actions after the plan has been finalized and approved.
Audit Question 360 Response The staff asked if a visual inspection had been performed of the IP2 spent fuel pool and refuel cavity and if so, how extensive it was. The applicant stated that the accessible 40-percent of the IP2 spent fuel pool liner above the fuel racks and 100-percent of the IP2 spent fuel transfer canal liner has been visually inspected. The staff asked the applicant to provide a brief history of the IP2 spent fuel pool leak. In the early 1990s during a rerack, damage occurred causing a pinhole leak. The liner was subsequently repaired. During excavation to install a crane, dampness in the vicinity of a hairline crack in the concrete was observed. The applicant stated that the source of the dampness was thought to be residual water from the pinhole leak that came out during the excavation. The applicant installed vacuum boxes at the location of the hairline crack. Since the installation of the boxes, the applicant stated that it had not observed any leakage. The applicant asserted that there was no known leakage for the IP2 spent fuel pool at this time. The staff asked about the structural integrity of the concrete of the spent fuel pool. The applicant stated that it would look at the original design calculations to see how much margin exists and provide a summary of the findings. Also, the applicant stated that bore samples had been taken from the area of the previous crack, and it would provide the documents that contained the information on the bore samples.
Audit Question 361 Response The staff asked the applicant where the subject spalling on the containment had occurred. The applicant clarified that the spalling locations occurred on the vertical wall of the containment structure and not on the dome as suggested in the condition reports that the staff had previously reviewed during the audit. The applicant indicated that the spalling occurred on both IP2 and IP3 containments. The staff asked the applicant to provide clarification of the reason for the spalling. The applicant stated that the spalling was occurring in locations where there was insufficient concrete coverage over the cadweld sleeves and also in locations where anchors for scaffolding had been placed during construction. In these locations, cosmetic repairs were performed after the scaffolding was removed. The staff asked the applicant about the worst case margins in the concrete and rebar at the degraded areas, and for photographs and locations/dimensions of the spalls on both containments. The applicant stated that it would provide this information.
