CESSAR Amendment 9, Appendix 5A

Dear Mr. Thompson:

Reference (A) provided revisions to CESSAR Appendix 5A to reflect the results of Pressurizer Safety Valve (PSV) testing performed for Combustion Engineering (C-E) plants. Reference (B) incorporated those changes into CESSAR by means of Amendment 9.

During recent discussions with the NRC Staff, it became apparent that a data transposition error occurred in the generation of this change concerning the nozzle elevation of the PSV. CESSAR Appendix 5A Section 2.2.3.2 (page SA-4) incorrectly indicates the nozzle to be at the 107% level. The correct elevation is 100% level. This change will be reflected in a future amendment to CESSAR.

If you have any questions or comments concerning this information, please feel free to call me or Mr. T. J. Collier of my staff at (203) 285-5215.

Very truly yours, COMBUSTION ENGINEERING, INC.
