: 3. This affidavit is prepared for use in the above-captioned proceeding.
: 4. My testimony at Tr. 2777, 2779, 2785 and 2789 contains an error which I wish to correct.
: 5.      In response to a series of questions by Judge Linenberger I incorrectly characterized a nuclear explosion as requiring a sufficient rate of energy deposition to result in the generation of a shock wave .                      Although it was not my intent, I may have left the impression that this was an important damage mechanism in an LMFBR energetic CDA.
: 6. While shock wave propagation may (or may not) be an important determinant in the energetics of a CDA (i.e., in whether a large energetic vapor explosion could ever occur) [see generally Alan E. Walter and Albert B. Reynolds, Fast Breeder Reactors, Pergamon Press, 1981, pp. 654-660] shock wave production is not required for an explosion to occur.
: 7. Furthermore, in a CDA, or nuclear explosion in an LMFBR, the expansion of a high temperature pressure bubble of reaction products, or vaporized material (e.g. fuel) is                      thought to be the predominant damage mode (rather than shock wave propagation) for the slower time-scale pressure buildup of an LMFBR excursion as i        compared to a chemical high-explosive detonation.                      [ Walter and Reynolds, og. cit., p. 664.]
