December 2,1980 Docket Nos. 50-259 50-260 and 50-296 Mr. Hugh G. Parris Manager of Power Tennessee Va'iley Authority 500A Chestnut Street, Tower II Chattanooga, Tennessee 37401
Dear Mr. Parris:
Reference is made to your letter of April 15, 1980 regarding the capability of the Tennessee Valley Authority (TVA) simulator to provide engineering predictions to postulated accidents and plant transients. We have reevaluated our research program, particularly with respect to the data and other input being requested from organizations such as TVA, in view of the many other demands we have placed on you and other applicants / licensees as a result of TMI-2 Lessons Learned, Bulletins and Orders, etc.
The purpose of this letter is to solicit your cooperation and assistance in comparing RETRAN results with simulator results for loss of feedwater and loss of load transients in a BWR such as Browns Ferry.
Specifically, we would greatly appreciate the following:
1.
A Browns Ferry input deck for the RETRAN Safety Code.
2.
Scheduling, in the near future, time on the Browns Ferry simulator to ran the loss of feedwater and loss of load transients.
If one of the LOCA accidents (small break, large break or steam line break) could also be run on the simulator, this would also be a pprecia ted. Before making any simulator runs, we would suggest that we meet with your staff in Chattanooga to review the machines and to establish initial and boundary condition settings for the runs.
We would appreciate your consideration in this matter.
Sincerely, po to, hief Operating Reactors Branch #2 Division of Licensing cc:
