ATTN: Mr. A. J. Nardi y*e P. O. Box 355 w
Pittsburgh, PA 15230 Gentlemen:
Pursuant to 10 CFR Part 71, you are authorized to deliver to a carrier for transport waste which has been packaged in accordance with statements and representations made in your letters dated November 20 and December 15, 1980 and Janaury 12 and 20, and April 10, 1981 subject to the conditions stated below:

Model No.: 6400 2.
Package Identification No.: USA /6400/L( )F 3.
Drawings: Packaging is constructed in accordance with Protective Packaging, Inc., Drawing Nos.: 32106-1, Sheet 1, Rev. F; and 32106, Sheet 2; and either (1) Westinghouse Electric Corporation Drawing No. 2020D08, Sheet 1 and 2, Rev. 0; or (2) Babcock and Wilcox Company Drawing No. ll-D-2130, Rev.

Contents:
[
a.
Large decontaminated equipment waste of such size as not to fit into a 55 gallon drum (with legs or other readily removable appendages resoved). Not to exceed 5 grams plutonium within the package.
Equipment waste surfaces must be decontaminated to a smearable level 2
of no more than 150,000 dps/100 cm prior to fixation or until successive decontamination cleaning operations do not reduce the sn.earable contamination levels by more than ten percent. After fixation, equipment waste surfaces must have a smearable level of 2
contamination of no greater than 10,000 dpe/100 cm. Outer surfaces aust have a smearable level of contamination of no greater than 20 dpm/100 cm.
Prior to fixing of contamination, large equipment 2
waste must be inspected to insure that:
(a) all sharp or protruding objects have been removed or blunted, and (b) pipe caps, gasketed blind flanges, covers, etc., have been installed wherever possible.
Following such inspection, the inner surfaces must be fixed with
" strip" or " clear" coating.
The inner surface (s) may alternatively be fixed with a polurethane foam.

The large equipment waste must be enclcsed in a tight fitting box constructed of 1-inch thick plywood. The space between the equipment and the box must be filled with foam and between equipment (1/2" minimum foaa thickness).
b.
Decontaminated hard waste items, such as equipment, metal cans, tools, etc., shall be double bagged within 12-mil thick PVC, with each bag heat sealed. The total fissile quantity of all the sealed packages in one container must not exceed 200 grams.
Hard waste surfaces must be decontaminated to a smearable leni of 2
no more than 150,000 dpe/100 cm prior to fixation or until successive decontamination cleaning operations do not reduce the seearable contasination levels by more than 10 percent. After fixation, hard waste surfaces must have a smearable level of contamination of no 2
greater than 10.000 dpa/100 an.
Prior to fixing of contamination, hard waste must be inspected to insure that sharp or prctruding objects have been removed or blunted. Following such inspection, the outer surfaces must be fixed with " strip" or " clear" coating.
Hard waste items such as furnate shells, suffles, or other items with large cavities not accessible for decontamination must be foaming within the cavities. Surfaces that are not easily accessible, e.g., interiors of small diameter tubing and piping which were in contact with process operations, must be swabbed or immersed in cleaning solution to insure removal of residual material. Open ends of the tubing and piping aust be sealed using mechanical fittings.
i Two drums containing hard waste items designated as Westinghouse I.D. No. ARD-80-014 and ARD-80-016 which were packaged before March 23, 1981, may be packaged in the following manner:
Wiping and brushing of the comonents had been completed to remove all residual contamination.
The components were individually double bagged within 12-mil thick PVC bagging material. Each bag was heat sealed and assayed.
The items were foamed rigidly in place within a DOT Specification 17H 55 gallon steel drum, equipped with a standard drum closure, such that a minimum annular thickness of 2 l
inches was maintained between the waste packages and inner drum l
wall. A minimum thickness of 3 inches of foam (foamed in place) was maintained between the bottom of the drum and the lowernost waste package, and between the lid of the drum and the uppermost waste package. The foam has a nominal density of 0.029 g/cc.
The assay values for these drums are as follows:
ARD-80-014 = 45 grams ARD-80-016 = 53 grams l
Sealed packages of hard waste must be enclosed in a tight-fitting, 1-inch thick plywood box constructed in accordance with Westinghouse Electric Corporation's Drawing No. 1620E43, Sheets 1, 2, 3, and 4, l
Rev. 3; or a tight-fitting 3/16" thick corrugated steel box constructed in accordance with Rockwell Hanford Operations' Drawing No. H-2-91888,

The space between the packages and the box must be f'lled with foam to a minimum thickness of 1 inch.
Void spaces bei. ween the sealed packages must be filled with foam (1/2" minimum fcan thickness).
c.
Glove box absolute filters with sealed inlet and outlet areas must be double bagged within 12-mil thick PVC, with each bag heat sealed and packaged within DOT 5pecification 17H or 17C steel drums (maximus size of 55 gallons).
Each drum must be lined with a sealed plastic liner and equipped with a standard drum c hsure.
