- request, and a computer code certification.

be modified to include a provision to ensure that actions be taken for implementation of the CE transmittal of the addressable constants, or (2) the acknowledgement of receipt be changed to an acknowledgement of implementation.

No g/A procedures have been changed to avoid an undetected CPC/CEAC software error, but the software design personnel have received additional training in the g/A procedure.
An exercise of the Phase II test was performed in the afternoon by running the test cases in the Single Channel Test Facility.
About 50 percent of the test cases for the Dynamic Software Verification Test and Live Input Single Parameter Test were run.
The results agreed completely with the results listed in CEN-219(V)-P, Revision 1, "CPC/CEAC System Phase II Software Verification Test Report".
