Neutron transport studies in a water medium and in a cylindrical air duct in a water medium were performed. The calculations were carried out with neutron transport codes ANISN and PALLAS-SP for one dimensional spherical geometry, and also with PALLAS-CY program for two dimensional geommetry. The experiments were performed in a water shield of a pool type reactor JBR-4. Measurements were made by activation method. The calculated results were converted to the reaction rates to compare with the experimental results of absolute values. The agreement between the calculation and experiment appears to be fair. On etudie, ici, le transport des neutrons dans l'eau et le conduit cylindrique qui se trouve dans l'eau. On a calcule par ANISN et PALLAS-SP (une dimension) et PALLAS-CY (deux dimensions). Les experimentations ont eu lieu dans l'eau de protection du reacteur piscine JRR-4. On a mesure le flux scalaire par la methode d'activation. On est arrive aux valeurs absolues de la vitesse de reaction par le calcul, et elles se sont comparees avec les valeurs absolues de la vitesse de reaction par les experimentations. L'accord du calcul avec les experimentation etait assez bon.
