3. DESCRIPTION OF PROGRAM OR FUNCTION - The ChainFinder program looks for nuclide transmutation chains possible under neutron irradiation (a search for pure decay chains is available). The ways for transmutations include radioactive decay, neutron capture, fast neutron induced threshold reactions, neutron induced nuclear fission. During the chain search decay 'subbranchings' are considered also (the 'subbranching', for example: at Zr-95 beta- decay the daughter nuclide Nb-95 is formed in both the ground and metastable states).

4. METHODS - Algorithms of path finding.

The program allows user to search for transmutations of a given start nuclide state to produce the finish one. One has to input the start and finish chain states in the form like 'H-1', 'U-235g', 'U-235m', 'Hf-17m1', 'Hf-177m2' and then press 'Find' button.

5. RESTRICTIONS ON THE COMPLEXITY OF THE PROBLEM -

6. TYPICAL RUNNING TIME - The program is interactive.

7. UNUSUAL FEATURES - When neutron induced fission is to be taken into account, and the time limit for the search is small (it depends upon the PC speed) some obvious chains may be missed.

8. RELATED OR AUXILIARY PROGRAMS - NKE (IAEA1384) and CHAINSOLVER (IAEA1404).
