3. DESCRIPTION OF PROGRAM OR FUNCTION

KINIK is an inverse kinetic code that solves the inverse form of the point kinetic equations using the Runge-Kutta method. An optimization procedure is involved  to control the time step and to reduce the running time. Up to 24 delayed neutron groups of different types (in case of heavy water as moderator or beryllium as reflector) are considered. KINIK is commonly applied to determine reactivity worths and to calibrate absorber rods. Following a rod drop, neutron flux or power is recorded as a function of time and used as input.

4. METHOD OF SOLUTION

The inverse point kinetc equations are numerically solved for each time step using the Runge-Kutta method.  The input data resulting from measurements are first approximated by polynomials of maximum degree 10 using a least-squares approach.

8. RELATED AND AUXILIARY PROGRAMS

KINIK is a one of several small computer codes developed for the research reactors F, FRJ-2, AVR (in Juelich, F.R. of Germany), and DR-2 (in Riso, Denmark) within the framework of the IAEA Contract No. 3634/FG. The other codes are  CREMAT (zero-dimensional burnup); BURNY (position weighting burnup); and CURIAX (post-irradiation data for discharged fuel elements).
