SUBJECT:

INDIAN POINT NUCLEAR GENERATING UNIT NO. 3 - REQUEST FOR ADDITIONAL INFORMATION REGARDING AMENDMENT APPLICATION FOR ALTERNATE SOURCE TERM (TAC NO. MC3351)

Dear Mr. Kansler:

On June 2, 2004, Entergy Nuclear Operations, Inc. (Entergy) submitted an application for a proposed amendment to the Technical Specifications (TSs) for Indian Point Nuclear Generating Unit No. 3 to fully adopt the alternate source term (AST) methodology for design-basis accident dose consequence evaluations in accordance with 10 CFR 50.67. Specifically, the amendment would revise the TS definition regarding dose equivalent iodine and TS Section 5.5.10, Ventilation Filter Testing Program. The AST methodology for the fuel-handling accident was previously approved in Amendment No. 215, dated March 17, 2003.

The Nuclear Regulatory Commission staff is reviewing the information provided in the June 2 application and has determined that additional information is needed to complete its review.

The specific questions regarding containment sump pH and iodine removal coefficients are found in the enclosed request for additional information (RAI). The staff will provide possible questions regarding other areas of its review in a separate letter. During a telephone call on September 21, 2004, the Entergy staff indicated that a response to the RAI would be provided within 45 days.

Please contact me at (301) 415-1457 if you have any questions on this issue.

Sincerely,

/RA/

Enclosure REQUEST FOR ADDITIONAL INFORMATION REGARDING FULL-SCOPE ADOPTION OF ALTERNATE SOURCE TERM ENTERGY NUCLEAR OPERATIONS, INC.

INDIAN POINT NUCLEAR GENERATING UNIT NO. 3 DOCKET NO. 50-286 In a letter dated June 2, 2004 (ADAMS Accession No. ML041600619), Entergy Nuclear Operations (Entergy or the licensee) submitted an application for a proposed amendment to the Technical Specifications (TSs) for Indian Point Nuclear Generating Unit No. 3 to fully adopt the alternate source term (AST) methodology for design-basis accident dose consequence evaluations in accordance with 10 CFR 50.67. The Nuclear Regulatory Commission (NRC) staff has the following questions regarding the information provided:

1.

In order to complete its evaluation, the staff needs to review the general assumptions and calculations used by the licensee to prove that the containment sump pH will be maintained above seven throughout the duration of the accident.

Describe the procedure utilized for calculating the pH of the containment sump water during the 30-day period after a loss-of-coolant accident. If the calculations were performed manually, describe the methodology and provide sample calculations. If a computer code was used, provide the input to the code and the results calculated by it.

2.

NUREG-0800, Standard Review Plan Section 6.5.2, Containment Spray as a Fission Product Cleanup System, states that the coefficient representing the removal of elemental iodine by wall deposition is calculated and is used as input in a computer model used for dose calculations.

Provide the value calculated for the removal coefficient of elemental iodine by wall deposition. If this value was not needed in the calculations, provide the technical basis for not using it.

3.

NUREG-0800 states that the maximum decontamination factor (DF) is 200 for elemental iodine. If the DF results in a number less than 200, then it is expected that this new number will be used in the calculations as it is more conservative. In the Containment Spray Iodine Removal Model section of the IP3 Updated Final Safety Analysis Report (UFSAR), the licensee calculated the DF to be approximately 160. This number is reduced to 100 to account for the instantaneous plateout and this was the number used in your UFSAR analysis. On page 9 of the June 2 submittal, the licensee stated that it used 200 as the value for the DF.

Clarify the apparent discrepancy between the information in the June 2 submittal and the UFSAR. Discuss whether another DF was calculated for the AST amendment and provide its value.
