Program-name         Package-ID  Status
DYNAMF               NEA-0090/01 Tested

Machines used:
Package-ID     Orig.Computer                       Test Computer
NEA-0090/01    CDC 3600                            CDC 3600

3. NATURE OF PHYSICAL PROBLEM SOLVED - The reactor dynamics equation with respect to time.


4. METHOD OF SOLUTION - Integral method from Schmid (Geneva Conference 1958).


5. RESTRICTIONS ON THE COMPLEXITY OF THE PROBLEM - Number of delayed neutron-groups smaller than 30. Number of exponential-functions in the reactivity feedback function less than or equal to 30.
Number of exponential function in the special reactivity function less than or equal to 30. Number of time steps less than or equal to 2000.


6. TYPICAL RUNNING TIME - About 110 ms for each time step.


7. UNUSUAL FEATURES OF THE PROGRAM - The problem of an ideal reactivity jump can be computed very rapidly. The uranium and the moderator temperature can be computed.
The CDC-version of this programme gives a graph of the power, the internal and the special reactivity.
