Dear Mr. Howard:

I i About 4:00 AM, Monday, January 14, 1974, during inspection of the metal clad keyed top reflector elements, we found that there were burrs on some of the drilled holes in the bottom distribution plate and machining chips _.

i in the plenum area between the graphite box portion and the lower distri-

[ bution plate of some of these elements in the warehouse. One of the chips y found was about 1" in diameter, large enough to plug a coolant passage.

_ Up to this time, 28 elements had been inspected, seven of which had been  %%g"  :

installed in the reactor. 'I . 2 .

' Our plans are to remov the seven elements f rom the reactor and re-inspect ^ $ ' y the 28 elements previously inspeceed.

[ Very truly yours4 /
