Isotopic safeguards data bank (ISTLIB) and control program (MISTY). [MISTY]

As part of the U.S. program to provide technical assistance to the International Atomic Energy Agency (IAEA), the Pacific Northwest Laboratory (PNL) has developed a computer code and data bank to aid in the safeguards verification of spent fuel content at the head end of a reprocessing facility. A description and user instructions that uses isotopic safeguards techniques are presented for MISTY, a computer program for analyzing an isotopic data base (ISTLIB). The input, operating procedures, an… more

Application of artificial intelligence techniques to the acceleration of Monte Carlo transport calculations. [Application to MCN code]

The techniques of learning theory and pattern recognition are used to learn splitting surface locations for the Monte Carlo neutron transport code MCN. A study is performed to determine default values for several pattern recognition and learning parameters. The modified MCN code is used to reduce computer cost for several nontrivial example problems.
