This approach to hazard analysis should be named Fail-For-Sure. Since France and other countries obtain much of their power from nuclear reactors, it is worthwhile to inquire what if anything they have done to eliminate Fail-For-Sure? And obviously, does the use of Ada help in eliminating Fail-For-Sure? Bob Leif Robert C. Leif, Ph.D. Email rleif@rleif.com
