EOI the keyword used to terminate input.<br />

If the spray model is selected as the ESF in an engineered system, certain combinations <strong>of</strong><br />

components must be specified. One combination consists <strong>of</strong> SOURCE and SPRAY, with<br />

OVERFLOW optional. The other combination consists <strong>of</strong> TANK, PUMP, HEX, and SPRAY, with<br />

OVERFLOW optional. An example <strong>of</strong> the input <strong>for</strong> the latter combination is given below.<br />

14.3.3.5 Heat Excharw er. Five liquid-liquid heat exchanger options are available. The keyword<br />

SHELL invokes the appropriate heat transfer correlations <strong>for</strong> a shell and tube, single-pass heat<br />

exchanger. CROSS denotes a cross-flow heat exchanger; COUNTER, a counterflow type;<br />

PAIU4LLEL, a parallel flow type; and USER, a user-specified constant temperature drop across the<br />

hot leg. The heat exchanger component is used only with the spray ESF.<br />
