Please provide the type of cable insulation for the cable failures included in your response to GL 2007-01. Waterford 3 prepared its response using the Nuclear Energy Institute (NEI) guidance, providedin an industry letter dated March 16, 2007, "Guidance for Response to GL 2007-01."  The NRC provided additional guidance on how licensees should determine which cable failures are within the scope of GL 2007-01 in the NRC letter dated April 13, 2007, from Michael J.
