The predefine concrete compositions do not include any steel rebar. Because rebar can be on the<br />

order <strong>of</strong> 20% <strong>of</strong> the concrete mass in reactor cavities, a provision is included <strong>for</strong> the user to specify<br />

a rebar mass fraction in the concrete. This is done by means <strong>of</strong> the REBAR keyword in the<br />

CORCON input. Note that input was previously provided in the VANESA block <strong>for</strong> specifying the<br />

rebar fraction used by the VANESA model. This input is now obsolete and will be ignored; the<br />

VANESA model will now always use the CORCON value. Rebar is by default assumed to be pure<br />

iron (material FE); however, the user can override this assumption and specify other metals <strong>for</strong> the<br />
