APPENDIX B-SAMPLE INPUT AND OUTPUT
The following pages discuss DELSOL sample problems which illustrate many
of the features of the code and provide example input formats for the most com-
mon types of problems. The related output listings, as generated on a CRAY
computer, are attached in microfiche version in the back of this manual.
Sample Problem la - Optimization of an External Receiver Design
Problem Statement
The optimum external molten salt receiver design at power levels of 75 to 150
MWe with no storage is desired. An incident flux level of 0.85 MW/m2 is not
to be exceeded anywhere on the receiver. The initial performance data should
be saved for subsequent calculations, and the optimized field layouts should be
printed. The optimized design and field layout for a power level of 125 MWe
should be saved for a separate performance rerun.

Analvsis of Input
For any initial performance calculation in a design/optimization run
IPROB=4 must be specified. The results of this initial performance run are saved
on a file on Unit 10 by setting ITAPE=l. It is assumed that the solar subsystems
are the same technology as specified by the default values in the code, and so no
changes are necessary for the remaining performance input. Flux calculations and
automatic aiming should not be done for an initial performance calculation.
