Expansion thennal

Figure 8.58 shows the effect of carbon black on thermal expansion coefficient of rubber." Increasing rubber content contributes to a decrease of thennal expansion.

The linear dimensional change on aging is between nil and 0.2%. The thennal expansion coefficient is similar to other titanium alloys. 

Figures D-2 and D-3. Furthermore, the relative temperature expansions have another interesting effect. Assuming the fuel has an average expansion coefficient of aluminum (2o x 10 K ), while aluminum, stainless steel, or a molybdenum alloy cladding has average thennal expansion coefficients of 26 x, 6 x, and 5 X 10 K respectively, then as the temperature rises, the axial linear fuel density varies differently inside each of the three cladding materials. Correspondingly, the axial linear moderator density also varies in each of the three clad materials. Both of these linear density changes affect the moderator-to-fuel ratio and, hence, the degree of reactivity control that can be obtained from the moderator temperature coefficient.

The volume elements placed at each lattice site in the face centered cubic model were assumed to be bound to each other by van der Waals forces alone. We realize that this is not an accurate representation for polymer chains and should result in theoretical estimates for thennal expansion coefficients and compressibilities...
