The required testing has been delayed due to the extended shutdown at Palisades which was to be the imple-mentation site for the test (as discussed in the previously referenced submit-tals). Testing has been completed recently and evaluation of the data is in progress.

As discussed with Mr Walter Paulson of your staff on July 2h,1980, Consumers Power Company will submit responses to the open items of these generic issues by September 1, 1980.
