- 3. INDEPENDENT TECHNICAL REVIEW A. THE STANDARD WAS DEVELOPED UTILIZING TVA AND STONE & WEBSTER ENGINEERING CORPORATION EXPERTISE.
B. THE METHODOLOGY HAS BEEN REVIEWED AGAINST, AND FOUND TO BE IN ACCORDANCE WITH, THE STANDARDS ~0F SARGENT & LUNDY AND GILBERT COMMONWEALTH.
C. THE STANDARD WAS REVIEWED AND FOUND ACCEPTABLE BY BECHTEL AS PART OF THE EMPLOYEE CONCERNS PROGRAM.
- 4. IMPLEMENTATION OF THE REVISED STANDARD A. THE SELECTION OF POWER CABLE SIZES UTILIZING DS-E12.6.3 IS REVIEWED FOR ALL NUCLEAR PROJECTS BY THE TVA ELECTRICAL ENGINEERING BRANCH PERSONNEL WHO DEVELOPED THE STANDARD. THIS WILL CONTINUE UNTIL A HIGH LEVEL OF CONFIDENCE IS ACHIEVED IN THE PROJECT PERSONNEL.
