Dear Dr. Thadani:

]: Enclosed is the October monthly report for the activities sponsored by your Branch. Also included are the computerized budget sununaries and the fee I

recovery cost status for each program requiring it. I would suggest that you

, and your staff review the reports to determine whether there are any dis-crepancies. If there are, please notify the principal investigator.

. }. Note that the funds allocated for FIN A-3740 are nearly spent and that l/ the NRC program office was informed of this November 14, 1983 as required by q revised Manual Chapter 1102, dated September 24, 1982. Please send the

.] balance of expected funds so that the level of effort may continue without 3 interruption.

l The funds received for FINS A-3313, A-3725 and A-3728, as shown on the

.-]

financial status pages, do not reflect the additional $10,000, $400,000 and

$120,000 received in November for these programs, respectively.

i We hope this meets with your approval. If there are any questions re-garding format, distribution, or budget reporting, please contact Mr.

A. J. Weiss, Administrative Technical Assistant, FTS 666-4473.
