The reactor Melusine - radiation measurements carried out at the start of operation and during the first ascents to power; Pile Melusine - mesures de rayonnement effectuees au demarrage et pendant les premieres montees en puissance

Abstract

This report gives the results of radiation measurements carried out on the first C.E.A. swimming-pool pile, Melusine. The purpose of these measurements, which were carried out during the starting-up period and the first ascents to 1 MW power, is to check the radiation intensity levels near the pile and from this to verify the safety calculation methods used. In addition certain special measurements, such as those performed in and above the water of the swimming-pool, in the channels and outside them etc..., should make it possible eventually to define the conditions under which the pile may be used for special jobs with less protection. In the first part of the report are given the results of radiation measurements carried out during runs at low power plateaux not exceeding 500 W: in particular measurements at variable water levels in the water of the swimming-pool and on the axis of the open channels. The results given in the second part deal with radiation measurements performed in various parts of the premises, studies on the activation of the plugs in the experimental channels and of the materials in the forward compartment, and also of the radioactivity of the swimming-pool water and the air  More>>

(author) [French] Le present rapport a pour but de donner les resultats des mesures de rayonnement effectuees aupres de la premiere pile piscine du C.E.A.: la pile Melusine. Le but de ces mesures, effectuees pendant la periode de demarrage et les premieres montees a la puissance de 1 MW, est de controler les niveaux d'intensite de rayonnement aupres de la pile et par la de juger des methodes de calculs de protection utilisees. D'autre part, certaines mesures plus particulieres, telles que celles effectuees dans l'eau et au-dessus de l'eau de la piscine, dans les canaux et a l'exterieur de ceux-ci, etc..., doivent permettre de definir ulterieurement les conditions d'utilisation de la pile pour des fonctionnements particuliers avec des protections amoindries. Dans la premiere partie de ce rapport, sont presentes les resultats des mesures de rayonnements effectuees pendant des fonctionnements en palier des puissances faibles ne depassant pas 500 W; en particulier, mesures a niveaux d'eau variables dans l'eau de la piscine et dans l'axe des canaux ouverts. Dans la seconde partie, sont presentes les resultats concernant les mesures des rayonnements effectuees dans les differents locaux, l'etude de l'activation des bouchons des canaux experimentaux, des materiaux se trouvant dans le compartiment avant ainsi que l'etude de la radioactivite de l'eau de la piscine et de l'air de refroidissement des canaux.
