SUBJECT:

' Application For Authorization to Convert the HEU to LEU Fuel at the Manhattan College Zero Power Reactor. (Our letter of May 8, .1989)

Dear Mr. Miller:

In our submittal of May 8,1989 we included the ANL Report " Analysis for Conversion of the:

Manhattan College Zero Power Reactor from HEU to LEU Fuel". Ylcase replace the summary table (page ii) with the enclosed corrected page.

In addition, we are enclosing 2 sdditional copics of our Safety Analysis Report in which

~

corrections have been made in the order of presentation of pages 18 and 20, and Revision 5 of the Technical Specifications (Attachment II) is correctly oriented.

Sincerely.
