3. NATURE OF PHYSICAL PROBLEM SOLVED

Determination of gas-cooled fast reactor core proportions required to satisfy specified design constraints and computation of resulting performance characteristics.

[ top ]

4. METHOD OF SOLUTION

Combination of heat transfer, flow and geometrical relationships with imposed design requirements and nuclear data supplied as input in the form of the necessary fuel volume fraction and fissile density.

[ top ]

5. RESTRICTIONS ON THE COMPLEXITY OF THE PROBLEM

The code is usable for any reactor system employing round rod fuel elements incorporating within themselves all fissile, fertile, and diluent material used in the core.

7. UNUSUAL FEATURES OF THE PROGRAM

The program allows use of an arbitrary degree of surface roughening over all, or a portion of the elements, and can design for optional distribution of such roughening.
