Connecticut 06095 POWER H SYSTEMS Docket No.: STN 50-470F February 28, 1983 LD 018 Mr. Darrell G. Eisenhut, Director Division of Licensing U.S. Nuclear Regulatory Commission Washington, D.C. 20555

Subject:

CESSAR-F Load Limiter Tests

Reference:

Letter LD-81-097, A. E. Scherer to J. R. Miller, dated December 12, 1981

Dear Mr. Eisenhut:

Combustion Engineering (C-E) has committed to provide results of testing on load limiting devices in the reactor vessel lower key horizontal supports.

This commitment was transmitted via the Reference as part of Amendment 6 to CESSAR-F. Specifically, Section 3.9.1.4.1 states that the " specification for the procurement of these load limiting devices includes a requirement for a test to demonstrate conformance to the required characteristics ... test results will be provided to the Nuclear Regulatory Commission ...".

The required characteristics for the load limiters are currently specified in CESSAR-F based on generic normal, upset, and safe shutdown earthquake loadings. In actuality, the load limiters are now being tested under plant specific normal, upset and safe shutdown earthquake loadings. Therefore, conformance will be demonstrated for the plant specific loadings at the Palo Verde Nuclear Generating Station site and test results will be transmitted to Arizona Public Service (APS) for submittal on their docket. C-E will provide the information to APS in the second quarter of 1983, which is compatible with their projected licensing schedule.

Reference to the generic test results will be removed from CESSAR-F in the next amendment. If you have any questions on this change, please feel free to contact me or Mr. G.A. Davis of my staff at (203) 688-1911, extension 2803.

Very truly yours, COMBUSTION ENGINEERING, INC.
