RE: ISSUES Related to Waterford 3 LAR, TAC No. ME6049 Importance: High

Kaly, AADB staff would like to review the 10 CFR 50.59 evaluation that the licensee conducted that supports the indicated change to Waterfords current AOR for an postulated FHA. The reason for our request is because AADB cannot conduct a confirmatory analysis based on the currently docketed information available. Whereas if the AST was still the current AOR, I could have simply compared the licensees proposed changes against the docketed values provided in their AST amendment. However, being that their current AOR is no longer the AST analyses, but is now based on the AOR resulting from their change supported by their indicated 10 CFR 50.59 evaluation, I dont actually have any reference values to compare the proposed change against.

Therefore, I cant make a reasonable assurance finding on this LAR without reviewing the 10 CFR 50.59 evaluation to verify what the reference values for the current FHA AOR actually are.

Please let me know if you have any questions, comments, and/or concerns.

I have already forgiven you for your transgressions against me.

RE: ISSUES Related to Waterford 3 LAR, TAC No. ME6049 Kaly The differences between the Analysis of Record (AOR) and the original Alternate Source Term (AST) Safety Evaluation Report (SER) approved on 3/29/05 is since that time we have identified issues with the calculation, entered those into our corrective action program, and addressed them under the 10CFR50.59 process.

The criterion to evaluate whether NRC approval is required in the 10CFR50.59 process would be:

10CFR50.59(c)(2)(iii) Result in more than a minimal increase in the consequences of an accident previously evaluated in the final safety analysis report (as updated).

Since the difference between the AST SER and the AOR is a reduction (not an increase), it passes 10CFR50.59 criterion and does not require NRC approval.

Our submittal W3F1-2010-0009 identified the increase fuel failure does exceed the 10% criteria. Our submittal W3F1-2010-0009 Attachment 1 page 3 does ask for NRC approval of that change.

Billy, Can you have your engineers provide an answer?

Subject:

ISSUES Related to Waterford 3 LAR, TAC No. ME6049 Importance: High Kaly are you currently available for a discussion about this LAR. I have a general clarification question that I may have to ask the licensee if you are not able to answer it for me. Please consider the following:

In evaluating the licensees updated postulated FHA radiological dose consequences results, AADB staff used the following table as a comparison:

The concern that AADB will need for either you or the licensee to clarify is why is the ere an apparent difference between the doc cketed and/or submitted EAB, LPZ, and CR dose e values for the, 1) Baseline analysis of record (AAOR) as submitted in the LAR; 2) AST dose valu ues as document in Waterfords issued AST T amendment; and 3) Dose values as docketed in n the Waterford FSAR.

Can you or the licensee please explain the reason for the differences?

Baseline AOR (0.105 rem TEDE) and AST (0.10 Specifically, the CR values for the B 09 rem TEDE) exhibit more than a 10% diffference between the two values. Was there anotther license amendment that was approved betw ween when the AST amendment was issued until now that can document the change in values?  ?

I think that both of these above state ed questions can be resolve with a simple telecon nference with the licensee, but we can send a formal RAI if desired. Thanks.

Subject:

Waterford 3 LAR, TAC No. ME6049 Hi, This is regarding the Waterford 3 License Amendment Request to Revise the Technical Specifications Based Upon Revised Fuel Handling Accident (TAC No. ME6049) submitted by application dated April 13, 2011.

In order to meet the 1-year metrics, DORL staff needs all the SEs by March 20, 2012. I notice from the WPC records that the primary reviewers are: Shih-Liang Wu (SNPB),

Ogbonna Hopkins (SBPB), Janaki Raval (SCVB), Kent Wood (SRXB/SFT), and LaRay J. Benton (AADB). I presume that the review is on schedule and the SEs will be sent by 3/20/12.

The WPC records also indicated that that EICB (Subinoy Mazumdar), EEEB (Swagata Som), and ESTB (Ravinder Grover) will be concurring in the Amendment Package and, therefore, I do not expect any input from these 3 Branches. I will forward the Package, once put together, for parallel concurrence.

Thanks.
