This modification to our previous requests is based on changes to the Code which have occurred since our original submittal and which are not consistent with the positions previously submitted. NNECO currently considers compliance with the Code in these areas to be appropriate based on our current Code applicability.

Code Case N-389-1 has been incorporated into Section XI in the 1988 Addenda which is approved for use in accordance with 10CFR50.55a and thus represents the basis to determine that the requirements in this Code Case provide an acceptable level of quality and safety.

There are no commitments made within this letter.
