List one part of the SUBSAFE Engineering Philosophy.

Avoid committing to untried systems and concepts

• Ensure adequate redundancy in design so plant can accommodate equipment and system failures that will inevitably occur

• Require suppliers to conduct extensive life testing of critical system components

• Test new reactor designs by use of a land-based prototype of same design

• Extensive analysis, full scale mock ups, rigorous testing

• Concentrate on designing, building and operating the plant to prevent accidents, not just coping with accidents

400

This disaster was caused by the energy company not planning enough fail-safes in the design. This led to a failure caused by natural disasters.
