a DISTRIBUTION Docket File-Docket No. 50-341 PD31 Plant Memo MVirgilio NOTE T0: Walt Rogers, Sr. Resident Inspector JStefano Fermi-2 Plant Site RIngram MCaruso FROM:

John J. Stefano, Project Manager PD III-1, DRSP, NRR

SUBJECT:

TIA REQUEST RE:

FERMI-2 CONTROL CENTER MAXIMUM ALLOWABLE UNFILTERED INLEAKAGE ACCEPTANCE CRITERIA (AITS NO. F03015185)

In response to your query of December 9,1987, I can find no evidence in file that NRR responded to the subject TIA, transmitted by J. A. Hind memo to H. L. Thompson dated March 14, 1985.

I have however, obtained a memo from D. R. Muller to T. M. Novak dated April 10, 1985, copy enclosed, which addresses the TIA.

The enclosed memo has no specific conclusion and I am not certain if it in fact is responsive to the TIA.

Should we need to pursue further, I would suggest a supplemental TIA be transmitted by Region III accordingly.
