ASSEMBLAGE CONTROLE [3 records]

Record 1 2010-12-09

English

Subject field(s)
  • Nuclear Fission Reactors
CONT

Shutdown system for a nuclear reactor … Seven fuel and control assemblies are also employed in the reactor core. Assemblies are substantially similar to fuel rods, but for the addition of a cadmium rod jacketed in corrosion-resistant metal, which addition serves as a control rod. The control rod of each assembly is located within [the] thimble and essentially replaces the assembly of fuel rods. Six of the seven fuel and control assemblies are located around the three concentric circles of [the] reactor core and serve as safety rods.

Assemblages de contrôle. Le réglage et l’arrêt du réacteur sont assurés par la manœuvre d’éléments absorbants; ces éléments sont constitués par des grappes d’aiguilles en carbure de bore enrichi, gainées d’acier austénitique, se déplaçant dans un tube analogue aux tubes hexagonaux des assemblages combustibles et permettant leur refroidissement par le sodium.

CONT

Seam Testing Methods... There are number of procedures available which have applicability on different geomembranes ... the ultrasonic impedance plane method works on the principle of acoustic impedance. A continuous wave of 160 to 185 kHz is sent through the seamed liner and a characteristic dot pattern is displayed on a CRT screen. Calibration of the dot pattern is required to signify a good seam; otherwise, it is not. The method has potential for all types of geomembranes but still needs additional development work.
