Model No.: 6400 2. Package Identification No.: USA /6400/B( )F 3. Drawing: Packaging is constructed in accordance with Babcock and Wilcox Company Drawing No. 11-D-2130, Rev. O. 4. Contents: a. Large decontaminated equipment waste of such size as not to fit into a 55-gallon drum (with legs or other ra?.dily removable appendages removed). Not to exceed 200 grams plutonium within the package. Equipmentwastesurfacesmustbedecontaginatedtoasmearable level of no more than 150,000 dpm/100 cm prior to fixation or until successive decontamination cleaning operations do not reduce the smearable contamination levels by more than ten percent. After fixation, equipment waste surfaces must have a smearagle level of contamination of no greater than 10,000 dpm/100 cm. Outer surfaces must have a smeargble level of contamination of no greater than 20 dpm/100 cm. Prior to fixing of contamination, large equipment waste must be inspected to insure that: (a) all sharp or protruding objects have been removed, blunted or i protected with packaging me.terial, and (b) pipe caps, gasketed blind flanges, covers, etc., have been installed 81062307# C_

The inner surface (s) may alterr.atively be fixed with a po1urethane foam. The large equipment waste must be enclosed in a tight-is fitting 3/16" thick corrugated _ steel box constructed in accordance with Rockwell Hanford Operations' Drawing. No. H-2-91888, Sheet 1, Rev. O. The' space between the equipment and the box must be filled with foam (l" minimum foam thickness) and between equipment (1/2" minimum foam thickness). LAlternatively, gloveboxes decontaminated and fixed as described above may be broken down as follows: Glovebox windows are removed and separately packaged in 12-mil thick PVC bags and sealed. The inner bag is tape sealed and the outer bag is heat sealed. Glovebox panels are cut to dimensions to fit inside the 3/16" thick corrugated steel burial crates constructed in accordance with Rockwell Hanford Operations' Drawing No. H-2-91888,-Sheet 1, Rev. O. All sharp or protruding objects 4.re removed, blunted, or protected with packaging material. The glovebox panels are bundled such that internal box surfaces are facing inward. Cut glovebox panels from not more than one glovebox are banded with metal strap banding such that two metal strap bands in each dire: tion are placed around the length and width of the glovebox sections. THe glovebox window and cut panel packages are enclosed and foamed in place within the steel burial crate. Blocking or dunnage is placed within the steel crate to ensure a one inch foam barrier on the sides and bottom of the 3/16" thick steel burial crate. Likewise, dunnage is provided between the banded glovebox sections to maintain a.1/2" thick foam barrit: between banded packages. l l b. Decontaminated hard waste items, such as equipment, metal cans, toois, etc., shall be ' double bagged within 12-mil thick pVC, wit.. 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 level of no more than 150,000 dpm/100 cm2 prior to fixation or until l success'..e decontamination cleaning operations do not reduce the i -,4 .--.n- .a,

After fixation,t hard waste surfaces' must have c smearable level of contamination of no greater than 10,000 dpm/100 cm2. Prior to fixing of contamination, hard waste must be insoected to insure that sharp or protruding objects have been removed, blunted,.or protected with-packaging material.. Following such inspection, the outer surfact! must be fixed with " strip" or '" clear" coating. - Hard waste items 'such as furnace shells, muffles, 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 must be sealed using mechanical fittings. Sealed packages of hard waste must be enclosed in a tight-fitting 3/16" thick corrugated steel box constructed in accordance with Rockwell Hanford Operations' Drawing 'No. H-2-91888. Sheet 1, Rev. O. The space between the packages and the-box must be filled with foam to a minimum thickness of 1 inch. Void spaces between the sealed packages must be filled with foam (1/2" minimum foam thickness). c. HEPA filters with sealed inlet and outlet areas must be double bagged within 12-mil thick PVC, with each ba-heat sealed and packaged within DOT Specification 17H or 17C steel drums (maximumsize'of55 gallons). Each drum must be lined with a sealed plastic liner and equipped with a standard drum closure. Each drum must not eseed a fissile quantity of 60 grams. Sealed drums must be enclosed in a tight-fitting 3/16" thick corrugated steel box constructed in accordance with Rockwell Hanford Operations' Drawing No. H-2-91888, Sheet 1, Rev. O. The space between the drums and the box must be filled with foam to a ~ minimum thickness of 1 inch. Void spaces between drums must be filled with foam (1/2" minimum foam thickness). d. Soft waste items, such as sheeting, gloves, paper, prefilter media, polyethylene bottles, shoe covers, etc., must be double bagged in 12 mil thick PVC, with each bag heat sealed (bag size must not exceed 22" x 16" x 10") and packaged within D0T Specification 17H or 17C steel drums (maximum size of 55 gallons).
