20555 Subj: Request for Amendment to Certificate of Compliance 9044.
Dear Mr. MacDonald:
On March 12, 1979, we notified you of the non-conformance of our Model B3-1 shipping casks which were itsed for routine waste shipments under Certificate of Compliance 6058.
We immediately pursed interim alternatives to permit operation.of our facility to continue during the long term resolution of the B3-1 matter.
Our first alternative has not succeeded.
We are hereby pur-suring a second alternative, that being to amend the license of a similar cask to meet our needs.
Because of the hardship already created, the time already lost, and the potential impact on the world supply of nuclear medical products should our facility not be able to continue operating, we seek your assistance in expeditiously processing our request.
The Model GE-1600 cask licensed under Certificate of Compliance 9044 is constructed in a manner very similar to the B3-1.
The GE-1600 is licensed for larger quantities of special nuclear material and greater decay heat load.
However, each licensed form for the contents is in some way incompatible with the form in which we have packaged wastes for shipment in B3-1 casks.
We therefore request that the GE-1600 license be amend in the following manner to allow shipments of the contents currently licensed for the B3-1 cask:

'i' USNRC, Div. of Fuel Cycle & Materials Safety March 22, 1979 1.
Add a new section 5. (b) (1) (v) to Certificate of Compliance 9044 which reads as follows:
" (v) Byproduct material and uranium enriched in the U-235 isotope as solids, non-powder, and dry, which will not decompose at temperatures up to 5000F and packaged within DOT Specification 17H steel drums or equivalent.
The thermal decay shall not exceed 400 watts.
The U-2Ja ner package shall not exceed 350 grams.
The H/X shall not exceed 500."
2.
Replace Section 5. (c) (i) of Certificate of Ccmpliance 9044 with the following words:
" Contents 5. (b) (1) (i)
- 5. (b) (1) (ii), 5. (b) (1) (iii), or
- 5. (b) (1) (v) :
two (2) ; or" Because of the physical similiarities between the two casks, we find the approved contents of the B3-1 cask to be an equally acceptable form for the contents of the GE-1600 cask.
Further-more, the GE-1600 cask is already licensed for an equivalent content under Section 5. (b) (1) (i) of Certificate 9044.
Since our wastes are already packaged in the form normally accepted for the B3-1, they can not be repackaged in the form specified for the GE-1600.
The wastes we propose to ship are solidified in a metal con-tainment.
A Specification 17H steel drum is modified by weld-ing brackets to the inner walls to support two bolts which protrude through to cover.
All contents placed in the drum are dry; however, as a precaution a moisture absorbent material is placed in the drum to contain any dampness or condensation that could arise.
The form of the radioactive contents is as follows:
1.
Uranium target material with mixed fission products. -
This material is originally in solution. Af ter the fission gas is removed, the solution is placed in a capped metal container and solidified with concrete.
Criticality is not possible because the quantity of U-235 is limited to 350 grams.

g-USNRC, Div. of Fuel Cycle & Materials Safety March 22, 1979 l
2.
Irradiated materials
- All target materials are packaged in solid form.
They are generally mqtal tubes ap-proximately 13" long.
3.
Contaminated solids
- Also added to the drum are contaminated tools and equipment used in hot cell operations, bottles, syringes, and miscellaneous solid items.
After the drum has been filled with these materials, the drum is topped off with concrete and the gasketed cover is bolted on.
The steel drum and concrete seal forms a containment for the contents.
Since the radioactive contents are dry and in a solid, non-powder form a leak test would not be meaningful.
Pursuant to 10 CFR 170.31.11 we are attaching a check in the amount of $150.00 for the amendment fee.
Also, pursuant to 10 CFR 71.12 (b) (1) (iii), we request that Union Carbide Corporation, Tuxedo, New York (license numbers R-81 and SNM-639) be registered as a user of Package Identifi-cation Number USA /9044/B ( ) F which is licensed under NRC Certificate of Compliance Number 9044.
We appreciate your attention in expediting this matter.
If we can be of help, please call at (914) 351-2131 extension 345.
