Dear Mr. Tinkler:
Enclosed are results of MARCH calculations performed for the Sequoyah plant. Table 1 is a description of the cases rua, and a summary or the containment pressures.
Please call me at (614) 424-7522, if you have questions on these results or the modeling assumptions.
Yours very truly, s
