REQUEST FOR ADDITIONAL INFORMATION REGARDING ONE-TIME EXTENSION OF CONTAINMENT INTEGRATED LEAK RATE TEST FREQUENCY, INDIAN POINT NUCLEAR GENERATING UNIT NO. 2 (TAC NO. MB2414)
Dear Mr. Kansler:
In a letter dated November 30, 2001, Entergy Nuclear Operations, Inc. (ENO) submitted its response to a request for additional information (RAI) from the U.S. Nuclear Regulatory Commission (NRC) dated October 4, 2001. The October 4 RAI was related to a proposed amendment dated July 13, 2001, to the Technical Specifications for Indian Point Nuclear Generating Unit No. 2 to allow a one-time extension of the frequency for performing the containment integrated leakage rate test.
The NRC staff reviewed information provided in the November 30 RAI response. On January 29, 2002, the staff held a telephone conference call with representatives of your staff to inform them of several other areas of concern with the information supporting the request.
During the conference call, the NRC staff stated that it would provide ENO with the enclosed.
The ENO staff indicated that a response would be provided within 30 days.
If you should have any questions, please do not hesitate to call me.
Sincerely,
/RA/

Enclosure REQUEST FOR ADDITIONAL INFORMATION REGARDING ONE-TIME EXTENSION OF CONTAINMENT INTEGRATED LEAK RATE TEST FREQUENCY INDIAN POINT NUCLEAR GENERATING UNIT NO. 2 (IP2)
In a letter dated July 13, 2001, Entergy Nuclear Operations, Inc. (the licensee) requested changes to the IP2 Technical Specifications (TSs) to allow a one-time extension of the frequency for performing the containment integrated leakage rate test (CILRT). In a letter dated October 4, 2001, the NRC staff requested the licensee to provide additional information to support the change. On November 30, 2001, the licensee submitted its response to the request for additional information (RAI). Based on the information in the November 30 response, the NRC staff requires additional information as stated in the questions as follows:
- 1.
On the basis of its review of the July 13 application and November 30 RAI response, the NRC staff noted that the IP2 containment has a number of areas of spalled and cracked concrete, corrosion of exposed reinforcing bars and cadweld splices, and liner corrosion. The licensee stated that corrective actions for most of these degradations was not needed based on its engineering analysis.
The NRC staff notes that unobserved degradation can exist on the embedded (uninspectable) side of the steel liner of concrete containments. These degradations can only be found during visual examinations (VT-1 or VT-3) if the degradation is throughwall or by ultrasonic examination of the liner. With the areas of degradations observed at IP2 and the possibility of degradation in uninspectable areas of the containment liner, provide the basis for not performing an ILRT before August 2002 to ensure the leak tightness of the "as is" containment.
- 2.
The possibility of corrosion degradations in uninspectable areas of the liner or penetrations can potentially increase the area of liner leakage under a design-basis accident pressure or under one of the severe accident scenarios. This could give rise to leak rates in excess of 35La, (i.e., threshold limit for Class 3b accident; see Attachment 3 to July 13 application). For a dry pressurized-water reactor containment such as the IP2 containment, NUREG-1493, Performance-Based Containment Leak-Test Program, dated September 1995, estimates an approximate leak area of 6.5 square inches for a leak rate of 100% of containment air weight (1000La). Recognizing the potential for degradation in uninspectable areas at IP2, discuss how the potential leakage is factored into the assumptions for the fragility curves that affect the Class 7 sequences related to risk assessments for the requested period of the CILRT extension.
