3. NATURE OF PHYSICAL PROBLEM SOLVED

For calculation of thermal and hydraulic transients in an open channel core associated with a loss of coolant flow accident, the programme is a modified version of the WAPD programme CAT.

[ top ]

4. METHOD OF SOLUTION: Equal pressure drop over the core at any height.

[ top ]

5. RESTRICTIONS ON THE COMPLEXITY OF THE PROBLEM

The core is assumed to be divided into two regions, the first represents 'average channels' the second represents a small number of 'hot channels'.

6. TYPICAL RUNNING TIME

Computing time about 1 minute, most time is used for the printout.
