Dear Mr. Denton:

In the Matter of the

Docket Nos. 50-259 Tennessee Valley Authority

)

50-260 i

50-296 I

As committed in my letter to you dated' July 15, 1982, enclosed is revision 2 to the integrated schedule for the Browns Ferry Nuclear Plant. Also provided is a description of changes since the July 15 submittal and reasons for the changes.

We believe that the integrated schedule process has been and will continue to-be beneficial in enabling TVA to implement NRC-required modifications.. Any 5

additional modifications which are required during the timeframe encompassed by the enclosed schedule will have to be factored into the overall schedule i

and may require new deferment requests.

Revision 3 will be provided to you j

by July 15, 1983 Very truly yours, TENNESSEE VALLEY AUTHORITY i

Listed below is a summary of the changes made to the Browns Ferry integrated schedule since the July 15, 1982 submittal and the

[

reasons for the changes.

MODIFICATION REASON FOR CHANGE Feedwater Nozzle Cracking The test has been completed, (NUREG-0619) schedule pending results of the fracture mechanics analysis from i

NUTECH, Inc. Analysis delayed because of delays in information exchanges between TVA and NUTECH.

II.F.1.1 Noble Gas Change in scope of modification II.F.1.2 Iodine requires unit outage to complete.

III.A.1.2 Emergency Support Schedule pending requirements of SECY-82-111B.

IEB 79-02 and 79-14 Addition,al inspections required as stated in L. M. Mills' letter to J. P. O'Reilly dated October 7, 1982.

T Instrument and Control Bus Moved to earlier outages to support i

Problems and Reactor other NRC-required modifications.

Protection Systems MSIV Material not available to modify valve stems as NRC was informed during the TVA/NRC meeting on.

December 15, 1982.

i Install Refrigeration System Outage for unit 1 completion moved to Containment Monitoring later because material not Panels available and design incomplete.

Evaluate and Inspect Vent and New Item.
