Letter dated May 12, 1994, from W. D. Reckley, NRC, to N. S. Carns, WCNOC

Subject:

Docket No. 50-482: Reactor Vessel Structural Integrity Gentlemen:

This letter submits corrected tables of pressurized thermal shock (PTS) and upper-shelf energy (USE) information as requested by the Reference. The Reference transmitted tables that contained PTS and USE information for Wolf Creek Generating Station and requested that an accuracy review be performed on the information contained in the tables. This information was based on data that was taken from Wolf Creek Nuclear Operating Corporation's response to Generic Letter 92-01, ' Revision 1,

• Reactor Vessel Structural Integrity," and previously docketed information. Portions of this information were originally telecopied to Mr. W. D. Reckley on June 10, 1994, with subsequent changes made based on input from Westinghouse. Please review the attached corrected tables and update your database accordingly.

If you have any questions concerning this matter, please contact me at (316) 364-8831, extension 4000, or Mr. Richard D. Flannigan at extension 4500.

Verf truly yours,
