Nuetronentransportberechnungen mit der Monte Carlo Methode - Möglichkeiten und Probleme

A general survey was given about the problems and growing possibilities of the Monte-Carlo method applied to particle transport.
In particular the following items were considered:

• the mathematical foundations of Monte Carlo methods
• analog games
• nonanalog games and the possibility to obtain zero variance
• equation for the variance in the analog and nonanalog case, meaning of impor tance function
• danger of miscalculation connected with nonanalog games
• "Weight Window Method" and analytical investigations to improve this method
• alternative methods to decrease the statistical errors
• possibilities to calculate optimum weights
