Experiments prior to construction of the Rapsodie reactor (1962); Experiences preliminaires a la construction de la pile rapsodie (1962)

Abstract

Before proceeding to the construction of the various reactor components described in the paper 'Fast Breeder Reactor Rapsodie', many experimental studies of a hydraulic, thermal and mechanical character have been carried out, or are under consideration, to test the validity of the principles adopted in the Preliminary Project. This paper deals with the most important of these: 1. Studies of coolant circuit components: sodium pumps (mechanical or electromagnetic), Na-NaK and NaK ir heat exchangers, measuring instruments (flow rates, temperatures), sodium purification circuits, etc. 2. Studies in cooling of fuel and fertile assemblies: a) study of the sodium cooling carried out by means of hydraulic mockups (scale of 1: 1 or over) reproducing the flow of the coolant fluid in the piping, upstream from and inside the fuel and fertile elements. b) study of the cooling by gas and by immersion in lead, employed during handling and storage operations. 3. Studies of special reactor devices: fusible rotating linkage, parts of the control rod mechanisms. 4. Study of the reactor block and coolant circuits as a whole. This study is to begin at the end of the year. The mock-up, now nearing completion, reproduces on a scale of 1: 1 the installation  More>>

This study is to begin at the end of the year. The mock-up, now nearing completion, reproduces on a scale of 1: 1 the installation provided in the Preliminary Project and includes: the reactor block, to which is connected a high flow ate sodium circuit, permitting of long-term tests and thermal shocks, and also, a control rod testing circuit; complete installation of the 1 MW and 10 MW coolant circuits, the performances of which it will be possible to check under various operational conditions. 5. A safety study carried out on a 3: 10 scale mock p comprising the whole of the reactor block and shielding, with the object of limiting the effects of any accidental liberation of energy of an explosive character. (authors) [French] Avant d'entreprendre la realisation des divers elements du reacteur decrit dans le rapport 'Reacteur rapide surregenerateur RAPSODIE', maintes etudes experimentales, d'ordre hydraulique, thermique et mecanique ont ete faites ou sont envisagees pour verifier la validite des principes adoptes dans l'avant rojet. Ce memoire traite des plus importants: 1. Etudes d'elements de circuits de refroidissement: pompes a sodium (mecaniques ou electromagnetiques), eohangeurs Na-Nak et Nak-air, appareils de mesures (debits, temperatures), circuits de purification du sodium, etc. 2. Etudes de refroidissement des assemblages combustibles et fertiles; a) etude du refroidissement par le sodium, menee a l'aide de maquettes hydrauliques (echelle 1 ou superieure a 1), reproduisant l'ecoulement du fluide de refroidissement dans les tuyauteries, a l'amont des elements combustibles et fertiles et a l'interieur de ceux i; b) etude du refroidissement par gaz et par immersion dans le plomb, utilise pendant les operations de la manutention et de stockage. 3. Etudes de dispositifs speciaux du reacteur: joint tournant liquefiable, parties de mecanismes des barres de controle. 4. Etude du bloc pile et des circuits de refroidissement dans leur ensemble. Cette etude doit commencer a la fin de cette annee. Les installations, en cours d'achevement, reproduisent, a l'echelle 1, celles prevues dans le projet et comportent: le bloc pile auquel est associe un circuit de sodium a grand debit permettant les essais de duree et la realisation de chocs thermiques et, en annexe, un circuit d'essai de barres de controle; l'installation complete des circuits de refroidissement de 1 MW et de 10 MW dont les performances, dans les differents cas de fonctionnement, pourront etre verifiees. 5. Etude de securite effectuee sur une maquette a 1 echelle 3/10 de l'ensemble du bloc pile et de ses protections, dont l'objet est la limitation des consequences d'une hypothetique liberation d'energie accidentelle, d'allure explosive.
