Attachment Item 1 Results of the "1,000-hour Test" after SPDS implementation for confirmatory review.

2 Documentation that the information displayed on Cooper SPDS is readily perceived and does not mislead the operator (s) (Man-In-The-Loop Testing) .

3 Validation test plans and results.

It should be noted that the 1,000-hour Test was performed with the IE multiplexers supplied by a temporary power configuration. The results of this test remain applicable, however; as the final power supply to the IE multiplexers (divisional IE power) equals or exceeds the reliability of the temporary configuration.

Additional items of information, not presently available, will be submitted to complete the staff's review. These items will be submitted as they become available which is expected before June 15,1986. A list of these items is as follows: 0 t\
