3. DESCRIPTION OF PROBLEM OR FUNCTION

This modular package will calculate neutron flux in a geometry containing several void regions by using the removal diffusion method coupled with albedo-transport  equation.

4. METHOD OF SOLUTION:  Solution details are discussed in Ref.(1).
top ]
5. RESTRICTIONS ON THE COMPLEXITY OF THE PROBLEM

The principle restriction is the availability of adequate core storage. All large  modules are variably dimensioned which means that array sizes are set for the particular problem being run at execution.

6. TYPICAL RUNNING TIME

Running times for this system are a function  of several things:
(a) the number of removal neutron groups
(b) the number of diffusion neutron groups
(c) the number of spatial nodes in a calculation geometry
(d) the number of subdivisions at duct wall surfaces.

7. UNUSUAL FEATURES OF THE PROGRAM

For economical reasons, the program can be used more often for design purpose than discrete ordinates transport codes or Monte Carlo codes for in the early stade of practical reactor shielding design processes.

8. RELATED AND AUXILIARY PROGRAMS

TOKOSEN - plots contours of any activity such as flux or dose and            draws the input geometry model
GENSUIZU- provides one-dimensional plots of activities as selected            points from MADANNA.
