    Have X-rays been taken of the metal components to confirm that 
metallurical structures are sound?

    X-raying metals is a standard procedure in quality control.

    When I worked for Hamilton Standard, Division of United Aircraft (now 
United Technologies),
    One shipment of propellors was pulled back because they had been shipped 
without the X-ray check.

    Neutron bombardment and high temperature degrades the strength of all 
materials.

    This is basic.

    And,  not only will heat and radioactivity degrade strength but 
repetitious cycles of stress, causes
    fatigue.  All materials have a limited fatigue life.

    An independent metalurgist should  evaluate integrity  of the metals 
involved.

    When a structure is designed, a safety factor must be incorporated 
according to the structural code.
    The safety factor is necessary  to cover unforseen circumstances, and 
the fact that theoretical
    calculations do not anticipate everything.

    When the strength of materials in a structure is weakened, it reduces or 
eliminates the safety factor.
    Licensed Professional Engineers are not allowed to approve a design 
unless it has the required safety factor.

    Without it, the structure is not legal. A Professional Engineer can lose 
his/her license or be sued  if a structure
    was approved without this precaution.

    How did the people at AmerGen expect that epoxy paint can arrest liner 
rust?  Epoxy, or any
    coating, can only function if it is applied to absolutely clean rust 
free metal.  UNLESS A RUST FREE
    UNDERBASE EXISTS, NO COATING WILL ARREST RUST.   Elementary!
