Dear Dr. Murley:

Commonwealth Edison previously proposed the design and installation schedule l

for the ATWS Mitigation System (AMS) for the Braidwood Station in reference (a). The initial dest n and subsequent design changes were submitted in references (b), (c), (d), (e), (f), (g) and 1) based on NRC requests for information and teleconferences.

As previously discussed in reference (h), this modification was tied to the normally scheduled refueling outages for each unit. This modification has been cc oleted for Braidwood Units 1 and 2.

Please direct any further questions regarding these matters to this office.

Very truly yours, h1 k b O-Allen R. Checca Nuclear Licensing Administratur l
