Abstract

Somme elements of neutronics are presented in a simple and often intuitive way; the 'K infinite' and 'K effective' formulae are derived and discussed. The limiting solid angle method is explained and some simple formulae proposed for evaluating the interaction between 'fissile units'. The general principles used in studying the safety of nuclear installations using fissile matter are given. Practical rules, critical mass and critical geometry curves as well as all the numerical values required for normal criticality calculations are given for plutonium and uranium at various degrees of enrichment. This guide is not intended to produce experts in criticality and cannot replace the advice which can be given by specialists of a science which is still expanding rapidly. It should however simplify the task of these specialists by familiarising with these problems both the engineers and scientists in charge of the design of installations using fissile matter, and the persons in charge of their operation.

La 'methode de l'angle solide limite' est expliquee et des formules simples proposees pour evaluer l'interaction entre des 'unites fissiles'. Les principes generaux utilises dans les etudes de surete nucleaire d'installation, mettant en ceuvre des matieres fissiles, sont donnes. Des regles pratiques, des courbes de masse et geometrie critiques ainsi que toutes les valeurs numeriques necessaires aux calculs usuels de criticite sont fournies pour du plutonium et de l'uranium a divers enrichissements. Ce guide n'a pas la pretention de former des experts en criticite et ne doit pas dispenser de s'entourer de l'avis de specialistes dans une science encore en pleine evolution. II doit simplement faciliter la tache de ceux-ci, en familiarisant avec ces problemes les ingenieurs charges de la conception des installations traitant des matieres fissiles et les responsables charges de leur exploitation.
