May 23, 1984 Docket Nos. 50-259/260/296 Mr. Hugh G. Parris Manager of Power Tennessee Valley Authority 500A Chestnut Street, Tower II Chattanooga, Tennessee 37401
Dear Mr. Parris:
SUBJECT:
TVA RETRAN REPORT Re:
Browns Ferry Nuclear Plant, Units 1, 2 and 3
Our letter of April 7, 1983 advised you that your report, "BWR Transient Analysis Model Utilizing the RETRAN Program,"
TYA TR 81-01, was acceptable for referencing by TVA in licensing actions with regard to the analysis of limiting pressurization transients in reload evaluations for TVA BWR plants.
In our letter, we placed two conditions on our acceptance, one of which related to use of approved methods to generate values of gap conductance.
To remove this condition, you submitted by letter dated November 21, 1983 a report, "Validation of COMETHE III-J for Gap Conductance Calculations."
We have completed our review of the above report and other related materials submitted by the Tennessee Valley Authority regarding the use of the fuel performance code COMETHE III-J in the analysis of BWR transients.
As discussed in the enclosed evaluation, we have concluded that you have demonstrated an acceptable method of providing initial fuel conditions to the previously-reviewed transient analysis
- model, RETRAN.
Our approval is limited to the analysis of non-LOCA transients as described in TVA TR 81-01 and performed by the Tennessee Valley Authority.
The condition in our letter of April 7, 1983 regarding gap conductance calculations is hereby removed.
At the time of our review of your transient analysis model, the generic review of the basic RETRAN computer codes, upon which your TVA-RETRAN was
- based, had not been completed.
- Hence, we had included a second condition in our letter of April 7, 1983 to advise you that unexpected developments in our generic review could affect the approval granted in our letter of April 7, 1983 on the manner in which the RETRAN results are applied.
.We have now completed our generic review of the RETRAN code.
The possible restriction on your use of the RETRAN computer codes is hereby removed.
Thus TVA TR 81-01 is approved without conditions for referencing by TVA in core reload analyses performed by TVA for BWR facilities operated by TVA.
