On peut signaler la détection, en juillet 1979 lors des essais physiques à puissance nulle de la tranche de Bugey 5, d'une anomalie particulière survenue sur les crayons de poisons consommables réalisés en Pyrex (verre silico-boraté). Ces crayons étaient fabriqués en deux parties; celles-ci s'étaient séparées lors du transport, laissant apparaître un vide qui avait provoqué un pic de flux au milieu du cœur.  1, record 1, French, - crayon%20de%20poison%20consommable

The crystallographic textures of zirconium alloy tubing used as cladding in nuclear reactor fuel are commonly characterized by the quantitative texture numbers F(Källström) and f_{lower case r}(Kearns) which are derived from the direct and inverse pole figures. The texture numbers of zircaloy 2 and 4 tubes have been correlated experimentally with the value of the contractile strain ratio R which is a measure of the plastic anisotropy of the tube.  1, record 9, English, - contractile%20strain%20ratio

Matériaux de gainage des réacteurs à eau. [...] Comme les contraintes principales en service dans une gaine sont, majoritairement, circonférentielles, on en déduit que le mode de fabrication doit éviter une texture trop tangentielle pour que les hydrures ne réduisent pas considérablement la ductilité des tubes. C'est pourquoi des critères sur l'orientation des hydrures, la texture et le coefficient d'anisotropie mécanique en traction, plus communément connu sous le nom de CSR (contractile strain ratio) ont été instaurés.  1, record 9, French, - coefficient%20d%27anisotropie%20m%C3%A9canique%20en%20traction
