Crud and Galvanic Corrosion:

A main potential problem is crud. Crud could cause an increase within background radiation levels.  While two dissimilar metals are within close vicinity, the opportunity for ion transfer is high.  An output is a perfect environment for galvanic corrosion.  As of the numerous categories of materials used in nuclear facilities then galvanic corrosion is a main concern.

  STATE the two conditions which could cause galvanic corrosion.

  EXPLAIN the mechanism for galvanic corrosion.

  IDENTIFY the two locations that are susceptible to galvanic corrosion.
