Dear Mr. MacDonald:
In resoonse to the request in your letter dated February 29, 1980, the following information is provided:
On April 23, 1980, Ouality Assurance inspected the Model 6400, "Supertiger" shipping packaoe identified as L-1, NUMEC property tag No. 202310, for conformance with Protective Packaging, Inc. Drawinas No. 32106-1, Sheet 1, Revision F, and 32106, Sheet 2.
Only those dimensions and characteristics which could be evaluated without dismantling the container were inspected.
In addition, the container was examined to determine the extent of any damage or deterioration of the package and the presence of holes or cracks in the inner liner.
The attached inspection report lists the characteristics inspected, the drawing specification and the observed measurement. The measurements found to be outside the drawing tolerances are indicated.
A visual examination of the nackage revealed no cracks or holes in the inner liner of the package.
However, several conditions were observed which require repair before the container is again used for nuclear material shipments.
(1) The inner surface of the cap (outer door) will be scraped, new sealant applied and repainted.
(2) The gasket on the inner surface of the cap will be replaced.
(3) The gasket on the inner surface of the closure plate (inner door) will be reglued in several places.
(4) The inner door gasket nating surface of the container will be scraped and repainted and the wood surface adjacent to the mating surface will be resealed and painted.
