Dear Sir or Madam:

This letter provides an update to a Nuclear Regulatory Commission (NRC) request for additional information transmitted by Reference 1. In that letter, the NRC requested that Indiana Michigan Power Company (I&M) provide additional information as to why a referenced reactor vessel head drop analysis should not be included in the CNP Updated Final Safety Analysis Report (UFSAR).

I&M responded to the NRC request by Reference 2.

I&M has completed formal, plant-specific, reactor vessel head drop analyses for CNP Units 1 and 2 and updated the UFSAR accordingly. Additionally, I&M is participating in the industry initiative on heavy load lifts to ensure that heavy load lifts continue to be conducted safely, and that the CNP licensing bases accurately reflect plant practices. I&M intends to implement applicable recommendations made by the indutstry task force on heavy loads as they become available.

This letter contains no new or revised regulatory commitments. Should you have any questions, please contact Ms. Susan D. Simpson, Regulatory Affairs Manager, at (269) 466-2428.
