STEAM DRYER STRESS REPORT ADDENDUM (TAC NOS.
- MC3812, MC3743, AND MC3744)
By letters dated June 28, 2004 (ADAMS Accession No. ML041840109) and June 25, 2004 (ML041840301),
TVA submitted applications to the NRC for EPU of BFN Unit 1 and BFN Units 2 and 3, respectively.
In support of the applications for EPU, TVA is providing certain engineering reports to demonstrate that the structural integrity of the BFN steam dryers will not be challenged under EPU conditions.
These reports include steam dryer benchmarking, scale model testing, and stress analysis reports for the BFN steam dryers under EPU operating conditions.
By letters dated March 9, 2006 (ML060720303),
April 13, 2006 (ML061070627),
and May 5, 2006 (ML061300436),
TVA provided the GE scale model steam dryer benchmarking report, the BFN scale model test report, the CDI load definition benchmarking report, and the BFN steam dryer (unmodified) stress report, respectively.
This letter transmits an addendum to the BFN steam dryer stress analysis report, representing planned steam dryer modifications.
The stress analysis results for the modified
U.S. Nuclear Regulatory Commission Page 2 June 23, 2006 steam dryer at EPU conditions demonstrate that the BFN steam dryer stresses are generally below the endurance level screening criteria.
However, when conservative stress amplification factors are applied to address local stress intensification, a few dryer components are predicted to exceed design limits.
This is a consequence of the conservative elements in the program used to develop the load definition.
Due to the results of the stress analysis, and to verify steam dryer performance at EPU conditions, TVA is developing a Steam Dryer Monitoring Plan (modeled after the Steam Dryer Monitoring Plan of another BWR having recently achieved EPU) that will include limit curves to ensure that adequate structural margins are maintained during EPU power ascension.
TVA expects to provide the steam dryer limit curves to the NRC by July 21, 2006. is the addendum to the BFN steam dryer stress analysis report, entitled "Addendum to Browns Ferry Nuclear Units 1, 2, and 3 Steam Dryer Stress, Dynamic, and Fatigue Analyses for EPU Conditions," prepared by General Electric.
This report provides a summary structural analysis of the modified steam dryer at EPU conditions.
Please note that the stress analysis report version in contains information that the General Electric Company (GE) considers to be proprietary in nature and subsequently, pursuant to 10 CFR 9.17(a) (4),
2.390(a) (4) and 2.390(d) (1),
requests that such information be withheld from public disclosure. contains the redacted version of the report, with the GE proprietary material removed, which is suitable for public disclosure. contains an affidavit from GE supporting this request.
There are no new commitments contained in this letter.
If you have any questions regarding this letter, please contact me at (256)729-2636.
I declare under penalty of perjury that the foregoing is true and correct.
Executed on this 2 3rd day of June, 2006.
