<p>A technique for reducing the shadow corrosion effect in zirconium-based alloys (12) caused by beta -particles emitted by adjacent components (14) containing one or more elements that emit beta -particles flux when activated by neutron capture. The technique entails providing a coating capable of absorbing beta -particles, so as to mitigate the adverse effect of beta -particle bombardment of a zirconium-based alloy. Preferred coating materials include beryllia, beryllium, tin, zinc, chromium, and cadmium. The coatings can be applied to various nuclear reactor structural alloys, such as stainless steel and nickel, platinum, copper, hafnium, and yttrium-based alloys containing 0.2 weight percent manganese or more. <IMAGE></p> |
