Assessment of the Structural Performance Capability as Potentially Affected by Settlement induced Cracking Gentlemen:
Attached is our recently completed engineering evoluotion of the structural performance copobility of the diesel generator building. This evoluotion was undertaken in accordance with the defined scope of the IDCVP os part ot.our l.

We are transmitting it to you because of its relevance to ongoing discussions concerning the potential effects of settlement induced cracking on the copobility of the DGB to meet intended performance requirements over its service life.
We have concluded that the existing cracks, generally being of small size, are not indicative of a condition that would compromise the capability of the DGB in meeting its intended performance requirements. Furthermore, it is judged that significant future cracking is unonticipated and the DGB is expected to remain serviceable without further remedial action at this point in time. We have I

Multiple Addressees reviewed Consumers Power Company's commitments to verify continued serviceability and have concluded that these are acceptable; however, we have offered certain recommendations for consideration that are intended to improve available information and reduce operational constraints.
Should you desire further articulatien of the bases for our conclusions, we would welcome the opportunity for discussion.
