Mr.-Charles MacDonald, Chief Transportation Branch i
Division of Safeguards and Transportation NMSS US Nuclear Regulatory Agency Washington, DC 20555
Dear Mr. MacDonald:
We request an amendment to USNRC Certificate of Compliance i.
Number 6717 issued for the Model 6717 Type B(U) package.
I:
We: request that the gross weight of the package be increased L
to 100 pounds.
This will allow us to ship several heavier source changers that would presently exceed the certificate limit of 75 pounds.
l In support lof this request we have performed the 30 foot free-fall test'(71.73-(c)(1)), the puncture; test (71.71 (c)(9)) and the compression test (71.73(c)(2)) on a 6717 l
barrel weighing 100 pounds.
Test reports are enclosed, l.
showing'the satisfactory completion'of these tests on the heavier 6717 barrel.
The increased weight will not adversely affect the ability of the package to meet any of the other normal conditions of transport or. hypothetical accident conditions of transport.
The 6717 barrel has already proven to meet all the requirements of a Type B(U) package based on the. initial l
submission by Gamma Industries dated June 1975.
I have enclosed an application fee of $150.00 to cover the cost of this amendment.
Please contact me if you require l
any additional information.

Compression Test of 6717 Barrel
' A1 compression test _was performed on 13 October 1989 on a:
Model'6717Lbarrel-to demonstrate that it would successfully
. pass the compression-requirements of 10CFR71.
' A load of 500-lbs was uniformly distributed on the horizontal 2y projected area of the 6717 barrel.
This was f

Model 6717 puncture Test-x
- On 29 September.1989, a' prototype Model 6717 package with a gross weight of 100:1bs'was subjected to a puncture test in accordance with'
- the requirements of 10 CFR 71.73(c) (2) and IAEA Safety Series No. 6, paragraph 719(b).
This test.was performed at. Valley Tree Service, Groveland, MA.
IImmediately following the free drop test, the prototype Model"6717 p2ckage'was dropped'from a height'of one meter onto a: target.
The
.tcrget-consisted of a right circular cylindrical steel ~ billet 152mm (6; inches)-in diameter;and 203mm (8 inches) high mounted onto the target.used in the. free drop tests.
During.the drop ~, the package. impacted the target squarely on the top of the' barrel; There was no observable additional deformation as a rssultfof this drop..
y
'Ac a result of this test, there was no impairment of any design or Eccfety features.of the package.
There was no structural damage'to the locking. assembly orfpackage closure.
There was no release of the pnckage: contents.
- A shielding. efficiency test performed subsequent to completion of the Model 6717 test program demonstrated that these puncture tests did.not r: duce the shielding efficiency of the package.

Model 6717 Free Drop Test
+
nd;On 29 September-1989, a prototype Model 6717 package with a gross _
^ weight of 100-lbs was subjected to a free drop test in accordance with tha requirements of 100 CFR 71.73(c)-(1) and IAEA Safety Series No. 6,
~
p2ragraph 719(a).
This test was performed at Valley Tree Service, Croveland', MA.
\\
.Tha Model 6717 package was dropped from a height of 9.1 meters (30
-fcat) onto a' target. -The target consisted of a concrete cube, each
' cide measuringLl.2m (48. inches) upon_which had been wet floated a ottel' plate:0.9m (36 inches) wide, 0.9m (36-inches) long and 25mm (one inch)1 thick. 'This target conforms to the guidance for an essentially unyielding surface as prescribed in paragraph 7.01 of IAEA Safety Saries No. 37.
,During the drip, the package impacted the target on the top of the
, barrel.- The barrel <was deformed approximately 3 inches..
The top of h
thF barrel: remained. secure with the clamp ring attached.
L A3-a result of thisstest, there was no impairment of any design or esfety features of the package.- There wasEno structural damage to the locking assembly or package closure.
There was no release of the packagelcontents.
A chielding efficiency test performed subsequent tot he completion of etha Mode 116717 test program demonstrated that the-free drop tests did not reduce'the shielding efficiency of the package.
