O Department of Energy Washington, D.C. 20545 Docket No. 50-537 HQ:S:83:247 APR 2 71983 Dr. J. Nelson Grace, Director CRBR Program Office Office of Nuclear Reactor Regulation U.S. Nuclear Regulatory Commission Washington, D.C.

Dear Dr. Grace:
PRIMARY HEAT TRANSPORT SYSTEM (PHTS) BRANCH LINE' EVALUATION
Reference:
Letter, J. Ebersole to N. Palladino, "ACRS Report on the Clinch River Breeder Reactor Plant," dated April 19, 1983 During the April 14, 1983, Advisory Committee on Reactor Safeguards (ACRS) meeting on the Clinch River Breeder Reactor Plant, members raised questions about the adequacy and significance of small PHTS branch lines. Although several questions were answered during the meeting, the referenced letter suggested that the branch lines be evaluated further.
We have undertaken evaluations in response to the ACRS suggestion. The ability of branch lines to withstand seismic events greater than the safe shutdown earthquake and the consequences of branch line failure are being evaluated. We will forward the results of our evaluations to you on or before May 17, 1983.
If there are any questions regarding this matter, please contact Mr. D. Florek (FTS626-6188) or Mr. A. Meller (FTS 626-6355) of the Project Office Oak Ridge staff.
l Sincerely, John R. Longenecker Acting Director, Office of Breeder Demonstration Projects Office of Nuclear Energy 7
